"Hutan mangrove merupalan ekosistem hutan yang khas terutama karena posisinya sebagai peralihan antara ekosistem darat dan ekosistem taut. Kondisi lingkungan fisiknya yang sangat khusus menyebabkan ekosistem mangrove memiliki keanekaragaman hayati yang terbatas dan ekosistem ini sangat rentan terhadap adanya pengaruh luar terutama karena species biota pada hutan mangrove memiliki toleransi yang sempit terhadap adanya perubahan dari luar.Hutan mangrove di Indonesia saat ini tinggal 3,24 juta hektar (Yayasan Mangrove, 1993). Sulawesi Tengah salah satu propinsi yang memiliki luas hutan mangrove hanya 28.000 ha, namun ancaman untuk eksploitasi menjadi tambak dan kegiatan Iainnya cukup tinggi.Hutan mangrove di Banawa Selatan yang luasnya 1167 hektar pada tahun 1973 dan pada tahun 1998 tersisa 167 hektar. Penurunan jumlah tersebut disebabkan beberapa faktor yakni :

1. Konversi hutan mangrove
   Kawasan pesisir Banawa Selatan yang ditumbuhi oleh hutan mangrove telah di dikonversi menjadi tambak udang dan ikan bandeng.
2. Areal Permukiman
   Bertambahnya jumlah penduduk baik karena pertumbuhan alamiah maupun karena migrasi telah mendorong meningkatnya permintaan akan areal permukiman.
3. Sistem Pertanian
   Sistem pertanian yang dikembangkan di Banawa Selatan sangat variatif mulai dari perladangan berpindah, pertanian menetap, maupun pertanian tambak telah mendorong meningkatnya tekanan terhadap hutan mangrove.
4. Pengelolaan tataguna lahan
   Pengelolaan tataguna lahan yang tidak memperhitungkan daya dukung dan kesesuaiannya, telah menyebabkan zona lindung pun telah berubah fungsi menjadi areal permukiman dan pertanian.
5. Perubahan struktur mata pencaharian
   Perubahan struktur mata pencaharian dialami oleh etnik Kaili Da'a dan Kaili Unde sebagai peladang dan nelayan tradisional menjadi petani tambak, menyebabkan degradasi hutan mangrove terus meningkat.

Kelima faktor tersebut menjadi dasar pertimbangan penulis melakukan penelitian dengan judul Perubahan Pofa Adaptasi Etnik Kaili Dalam Pengelolaan Mangrove, Studi kasus etnik Kalil Data dan Kaili Unde di Banawa Selatan, Kabupaten Donggala, Propinsi Sulawesi Tengah.Maksud dilaksanakannya penelitian ini untuk menyusun tesis sebagai salah satu syarat mendapatkan gelar Magister Sain (M.Si) Ilmu Lingkungan pada Program Pascasarjana Universitas Indonesia. Tujuan utama yang hendak dicapai dalam penelitian ini adalah urrtuk memperoleh gambaran kaitan antara perubahan pola adaptasi dan degradasi hutan mangrove, serta menghasilkan suatu konsep pengelolaan hutan mangrove yang berkelanjutan di Banawa Selalan.Gambaran hubungan perubahan pola adaptasi etnik Kaili dalam pengelolaan hutan mangrove di Banawa Selatan dan pola pengelolaan hutan mangrove yang berkelanjutan sebagai berikut :

1. Hubungan perubahan pola adaptasi dengan eksploitasi hutan mangrove. Eksploitasi hutan mangrove terjadi pada akhir tahun 1970-an dan mencapai puncaknya pada awal 1990-an, ini terjadi karena masuknya kaum migran Bugis, Toraja dan Mandar yang mulai memanfaatkan hutan mangrove sebagai kawasan pemukiman dan areal tambak. Sementara bagi etnik Kaili hutan mangrove adalah kawasan yang terlarang untuk kegiatan pertanian dan permukiman, sebab ada nilai magis yang dikandungnya. Namun akibat proses interaksi dengan kaum migrant, lambat laun etnik Kaili mulai terlibat memanfaatkan hutan mangrove untuk pemukiman dan kegiatan pertanian tambak.
2. Penabahan pola adaptasi terhadap perubahan fungsi hutan menjadi lahan permukiman.
   Konsepsi etnik Kaili Da'a dan Kaili Uncle yang memagiskan kawasan hutan mangrove untuk kegiatan permukiman berubah, bersamaan dengan masuknya kaum migran Bugis, Toraja dan Mandar yang telah memanfaatkan hutan mangrove untuk perrnukiman tetapi tidak mengalami gangguan apa pun seperti wabah penyakit.
3. Perubahan pola adaptasi terhadap sistem pertanian. Erik Kaili Da'a dan Kaili Linde adalah peladang dan nelayan tradisional yang cenderung menjauhi hutan mangrove sebagai csmber mata pencaharian.
   Perubahan terjadi saat ini peladang menjadi petani tambak, maka yang terjadi adalah sistem perladangan tebang-bakar ditransformasikan dalam kegiatan pertanian tambak.
4. Perubahan pola adaptasi dengan pendapatan dan kesejahteraan.
   Berubahnya mata pencaharian dari peladang dan nelayan tradisional menyebabkan meningkatnya pendapatan dan kesejahteraan etnik Kalil Da'a dan Kaili Uncle pada sisi yang lain menjadi faktor penekan yang potensial terhadap eksploitasi hutan mangrove karena meningkatnya pendapatan akan meningkat pula akses modal terhadap hutan mangrove.
5. Sistem Empang Parit sebagai bentuk pengelolaan hutan mangrove yang berkelanjutan.
   Berangkat dari empat fenomena yang tergambar di atas, maka penerapan sistem empang parit, yakni suatu model empang/tambak yang tetap mempertahankan ekosistem mangrove antara 30 -- 70 % peneliti yakin dapat mempertahankan ekosistem mangrove yang ada, serta dapat mempertahankan fungsi daya dukung dari hutan mangrove baik dari sudut fisik ekologis maupun dari fungsi sosial ekonominya.

Berdasarkan temuan tersebut maka dapat disimpulkan hal-hal sebagai berikut :

1. Ekosistem hutan mangrove yang ada di lokasi penelitian telah mengalami penurunan luasan dari 1167 hektar pada tahun 1973, tersisa 167 hektar pada tahun 1998.
2. Perubahan lingkungan hutan mangrove menjadi areal budidaya tambak udang dan bandeng oleh para migran merupakan salah satu faktor perubahan pola adaptasi etnik Kaili Da'a dan Kaili Unde. Perubahan pola adaptasi tersebut dalam hal memanfaatkan hutan tidak hanya sebagai sumber bahan ramuan rumah tinggal, namun diolah menjadi areal tambak.
3. Cara pandang dan persepsi tentang kawasan hutan mangrove yang tidak lagi magis, salah satu faktor perubahan pola adaptasi etnik Kaili Da'a dan Kaili Unde dari menjauhi kawasan hutan mangrove menjadi memanfaatkan kawasan hutan mangrove untuk pemukiman.
4. Perubahan pola adaptasi etnik Kaili Da'a dan Kalil Unde juga terjadi pada sistem budidaya perladangan yang berpindah-pindah menjadi petani menetap baik pada sistem budidaya teresterial maupun pada sistem budidaya aquatik.
5. Peningkatan pendapatan dan kesejahteraan menjadi faktor daya tarik bagi etnik lokal untuk memanfaatkan hutan mangrove yang berasal dari pembagian hak ulayat seluas 2 (dua) hektar, sebagai sumber pendapatan dan ekonomi keluarga.
6. Untuk mencegah berlanjutnya konversi hutan mangrove menjadi areal pertambakan yang tidak ramah lingkungan, maka penerapan sistem pengelolaan tambak yang ramah Iingkungan mendesak untuk dilaksanakan.

Berdasarkan kesimpulan tersebut disarankan untuk :

1. Pemerintah Daerah Kabupaten Donggala perlu segera mendata kembali luas kawasan yang tersisa, selanjutnya mengeluarkan peraturan daerah tentang penetapan kawasan lindung pada kawasan yang tersisa tersebut.
2. Segera menerapkan sistern budidaya empang parit (silvofishery) pada kawasan yang telah berubah menjadi areal tambak.
3. Meningkatkan peran lembaga adat bagi masyarakat lokal setempat.
4. Perlu dilakukan suatu studi antropologis yang Iebih komprehensif, terutama menyangkut nilai dan tradisi masyarakat setempat.

Change in Adaptation Patterns in Mangrove Management.Mangrove forest is a special forest ecosystem due to, mainly, its position as a transition zone between terresterial ecosystem and a marine ecosystem. Its special physical environmental conditions have caused the mangrove ecosystem to possess limited biodiversity. This ecosystem is very susceptible to the presence of external influences, especially since the biota species in the mangrove forest have limited tolerant changes from outside.

Mangrove forests in Indonesia currently cover 3,24 million hectares (Yayasan Mangove, 1993). Central Sulawesi is one of the provinces that has mangrove forests, about 28.000 hectares, but exploitation by conversion to fishponds and other activities is quite high.

South Banawa had 1167 hectares of mangrove, but when this research was conducted only 167 hectares remained. This decrease is due to some factors as follows :

1. Conversion.
   The coastal area of South Banawa planted to mangrove forest has been changed into areas of milk fish and shrimp ponds.
2. Settlement Area.
   Increasing population both naturally and by migration has led to an expansion of settlement area.
3. Agriculture System.
   The agriculture system in South Banawa including shifting cultivation, permanent cultivation and fish pond culture, has led to increased pressure on the mangrove forest.
4. Land Use Management.
   Land use management without concern for its carrying capacity has caused the alteration of protected areas into settlement and agriculture areas.
5. The alteration of livelihood source structure.
   The conversion of the Kaili Da'a and Kalil Unde peoples from field farmer and traditional fishers to fish pond farmers has degraded the mangrove forest significantly.

This research was aimed at descriptively obtaining the relationship between change of adaptation patterns and mangrove forest degradation and to produce a concept of sustainable mangrove forest management for South Banawa. Changes in the adaptation patterns of the Kaili people in mangrove management can be described as follows :

1. The relationship between changes of adaptation pattern with mangrove forest exploitation :
   The exploitation of mangrove forests has occurred since the end of the 1970's and reached its peak in the early of 1990's. This Is caused by the coming of Bug is, Toraja and Mandar people to South Banawa where they converted mangrove Forest into settlements and fish pond. For the Kalil people the mangrove forest was considered forbidden for any activity including agriculture and settlement However, through the interaction process between them and the newcomer groups they slowly have become involved in converting mangrove forests into settlement and fishpond areas.
2. Change of adaptation pattern in the change of forest function into settlement area :
   The concept of Kalil Da'a and Kalil Untie people, who originally considered the mangrove forest as a forbidden zone, has changed simultaneously with the coming of Bugis, Toraja and Mandar ethnic groups to South Banawa. These newcomer groups have converted mangrove forests into settlement areas without ever experiencing any problems such as disease epidemics.
3. Change of adaptation pattern in agriculture systems :
   Kaili Da'a and Kalil Untie people were farmers and traditional fishermen who tended to avoid the mangrove forests as their livelihood source but since they have been influenced by other ethnic groups, from they have converted cut-andbum farming to fishpond culture.
4. Change of adaptation patterns with income and prosperity.
   Change of livelihood source from farming and traditional fishing has increased their income and prosperity but on the other hand this is a potential pressure factor on the existing mangrove forest.
5. The application of the ditch-embankment (sllvofishery) system as one type of sustainable mangrove forest management.
   The application of the ditch-embankment system (a model of embankment that maintains 30-70 % of the original mangrove ecosystem) can preserve the existing mangrove ecosystem and its carrying capacity both ecologically or economically.

Based on the research result, it can be concluded that :

1. Mangrove forest in the research field has decreased its width from 1167 hectares in 1973 into 167 hectares in 1998.
2. Change of physic environment has caused Kalil Da'a and Kaili Untie people after their adaptation pattern from exploiting mangrove forest as housing materials to becoming fish farmers that converting mangrove forest into open fishpond areas.
3. The new perspective and perception of Kaili Da'a and Kaili Untie people about the mangrove forest zone, i.e. that the mangrove forest has no magic value, again hs pushed them to convert mangrove forest to settlement areas.
4. Their relationship with Bugis, Toraja, Mandar and Javanese people since 20 years ago has stimulated the conversions of their cultivation system into fish pond farming in the mangrove forest.
5. The increase of income and prosperity of Kaili Da'a and Kaili Untie people has raised pressure to exploit the existing natural resource including mangrove forests.
6. To prevent the exploitation of mangrove forest continuously both by migrants and by local peoples, sustainable mangrove forest management with a ditch-embankment should be applied.

Therefore some suggestions are :

1. The local government (Donggala Regency) must resurvey existing areas of mangrove forest and then make a regional regulation about protecting this area.
2. The ditch-embankment system should be applied immediately within fish pond areas.
3. Increase the role of custom any institutions in the area.
4. Conduct a comprehensive anthropology study, focused on the culture system, a specially on local environmental knowledge and practices.

"Senyawa lipid tak tersabunkan (non-saponifiable lipid/NSL) dari daun dan akar dua spesies mangrove sekresi, yaitu Aegiceras corniculatum (L.) Blanco dan Avicennia alba Bl, dua spesies mangrove non-sekresi, yaitu Acrostichum aureum L. dan Excoecaria agallocha L dianalisis dengan penekanan khusus pada triterpenoid dan fitosterol. Identifikasi triterpenoid dan fitosterol dikonfirmasi dengan perbandingan waktu retensi pada kolom GC dengan standar otentik dan interpretasi spectrum GC-MS. Triterpenoid dan fitosterol merupakan proporsi utama NSL. Triterpenoid dan fitosterol masing-masing terdiri dari 7 dan 4 senyawa. Triterpenoid merupakan konstituen terbesar dari spesies Ac. aureum dan Ae. corniculatum di jaringan daun dan akar, dan di akar spesies E. agallocha. Berbeda dengan spesies tersebut yang kaya kandungan triterpenoid, senyawa fitosterol relatif dominan dalam akar Av. alba. Spesies Av. alba dan E. agallocha di daun dibedakan dari spesies yang lain bahwa kedua spesies tersebut mengandung jumlah yang lebih besar dari senyawa fitol. Spesies Ae. corniculatum mengandung sejumlah besar konten betulin dan α-amyrin di akar, serta lupeol di akar spesies Av. alba. Keragaman dalam komposisi NSL tercatat dengan jenis mangrove untuk kedua jaringan daun dan akar, studi ini menyarankan bahwa komposisi NSL pada daun dan akar tumbuhan mangrove dapat digunakan sebagai karakter kemotaksonomi untuk membedakan spesies.

Non-saponifiable lipid (NSL) of the fresh leaves and roots from two salt-secretor mangrove species, namely Aegiceras corniculatum (L.) Blanco and Avicennia alba Bl. and two non-secretor mangroves, i.e. Acrostichum aureum L. and Excoecaria agallocha L. was analyzed with special emphasize to triterpenoids and phytosterols. Identification of the triterpenoids and phytosterols was confirmed by comparison of their retention time on the GC column with those of authentic standards and on the interpretation of GC-MS spectra. Triterpenoids and phytosterols comprised the major proportion of NSL. The triterpenoids and phytosterols mainly consisted of 7 and 4 compounds. Triterpenoids were the largest constituent of Ac. aureum and Ae. corniculatum leaves and roots, and E. agallocha roots. In contrast to these triterpenoids-rich species, phytosterols were relatively dominant in the roots of Av. alba. The species of Av. alba and E.agallocha in the leaves were distinguished from the others in that both species contained a larger quantity of phytol. Ae. corniculatum contained a large amount of betulin and α-amyrin in the roots, as well as lupeol in the roots of Av. alba. The diversity in the NSL composition noted with mangrove species in both the leaves and roots suggested that NSL of mangrove leaves and roots can be used as chemot axonomical character to differentiate species.

"Litter production is one of the major nutrient enrichments in a mangrove forest. Investigation on nutrient components in litter will lead to evaluation of nutrient accumulation. Therefore, this research aimed to 1) evaluate litter production in tropical mangrove forest at Klong Khone, Samut Songkhram province, Thailand; 2) investigate carbon, nitrogen and phosphorus contents in litter; and, 3) observe sediment quality and existing mangrove condition in the study area. Litter and sediment were collected at Klong Khone, Samut Songkhram province in September-October 2015. Litter samples were analyzed for biomass production, and composition of carbon, nitrogen and phosphorus. Sediment samples were analyzed for pH, salinity, water content, grain size composition, organic carbon, total nitrogen and total phosphorus. Results showed that leaf, branch, and fruit litter production were 65.02, 47.94 and 19.03 g DW/m2/month, respectively. Carbon, nitrogen, and phosphorus content in the litter were 20.36, 0.37 and 4.47 mg/g DW leaf litter, respectively. The value of pH, salinity and water content of sediment ranged from 6.66-7.50, 3.30-9.28 ppt and 52.24-69.65%, respectively. Sediment was composed of fine sand (0.125-1 mm) 7.68%, silt (0.06-0.125 mm) 6.13%, and clay (smaller than 0.06 mm) 86.19%. By using statistical analysis (t-test), results showed no difference of all parameters between months. However, during the research, it was found that organic carbon decreased 2.37 mg C/g DW sediment; meanwhile nitrogen and phosphorus increased 0.44 mg N and 0.12 mg P /g DW sediment, respectively. Finally, carbon, nitrogen and phosphorus accumulation by litterfall were found to be 1877, 34 and 734 mg/m2/month, respectively. These results will help in clarifying nutrient dynamic pathway by mangrove trees which play an important role in coastal and estuarine ecosystem restoration."

"Marine microalgae are among the flora that inhibits the mangrove area. They play an important role as the primary source of organic carbon in marine food web. However, very limited study on the mangrove-isolated microalgae, especially on the fatty acids. The objective of the current study was to determine the fatty acid composition in mangrove-isolated Chlorella strains. Seven mangrove-isolated Chlorella strains were cultured in F and F/2 media. Their growth and fatty acid composition were measured after the stationary growth phase. Results showed the growth varied among the strains. the cell density, cell biomass and fatty acid composition were influenced by the medium-strength. polyunsaturated fatty acids (PUFAs) were detected in only four strains, the KS-MA1, KS- MA2, KS-MB2 and SE-MB1. the highest amount of PUFAs was obtained in the KS-MA2 (40.9 ± 0.8 % dry wt. in the F/2 medium and 35.4 ± 6.7 % dry wt. in the F medium) and in the KS-MB2 (37.6 ± 3.4 % dry wt. in the F/2 medium and 34.4 ± 4.8 % dry wt. in the F medium). the growth and productivity of Chlorella species were strains-dependent and regulated by the medium strength. thus, the production of fatty acids of interest from Chlorella might be manipulated by optimizing the culture conditions."

"Hutan Angke Kapuk merupakan kawasan hutan mangrove yang berlokasi di DKI Jakarta. Seiring dengan tingkat pertumbuhan penduduk, perkembangan industri yang semakin cepat menimbulkan dampak negatif pada Hutan Angke Kapuk yang merupakan kawasan hijau bagi kehidupan penduduk DKI Jakarta. Melihat kondisi tersebut maka penelitian ini menitikberatkan pada aspek sosial ekonomi masyarakat yang secara tidak langsung akan berpengaruh pada kondisi Hutan Angke Kapuk yang saat ini cukup memprihatinkan keberadaannya.Penelitian ini bertujuan untuk mengetahui peranserta masyarakat sekitar hutan mangrove dalam menunjang keberadaan kawasan Hutan Angke Kapuk. Selanjutnya hasil penelitian ini dapat digunakan sebagai masukan bagi penentu kebijakan dalam pengambilan keputusan untuk penkembangan pembangunan yang berwawasan lingkungan Selain itu juga dtharapkan dapat meningkatkan nilai tambah baik bagi Hutan Angke Kapuk itu sendiri maupun masyarakat sekitar.Berdasarkan permasalahan diatas, dapat disusun hipotesis sebagai berikutHo : Tinggi rendahnya tingkat pendidikan dan pendapatan masyarakat tidak mempengaruhi tingkat peranserta masyarakat terhadap Hutan Angke KapukHa,: Tinggi atau rendahnya tingkat pendidikan dan pendapatan masyarakat mempengaruhi tingkat peranserta masyarakat terhadap Hutan Angke KapukPenelitian ini menggunakan metode deskriptif dengan jenis penelitian studi kasus. Untuk menguji hipotesis digunakan tes signifikansi Uji Kai Kuadrat dan Analisis Regresi dengan program Statistical Product and Service Solutions (SPSS) versi 10.00. Data dikumpulkan melalui studi literatur, observasi, dan wawancara dengan berpedoman pada kuesioner dengan masyarakat sekitar kawasan Hutan Angke Kapuk.Hasil dari penelitian ini adalah:Pendidikan dan pendapatan ternyata tidak mempengaruhi tingkat peranserta dari masyarakat sekitar Hutan Angke Kapuk, jadi Ho tidak ditolak.

Angke Kapuk Forest is a mangrove forest area which is located in Province of DKI Jakarta. The growth Ievel of population and industry which happen faster nowadays have caused negative impacts to Angke Kapuk Forest which is a green zone for people's live at DKI Jakarta. Because of this forest plays an important role for DKI Jakarta development then there is special emphasis in implementation of policy and regulation/laws between central and local government especially for regional development which balances between local mangrove forest conservation and coastal area developing activity.Based on the statement above, this research is focus on the aspect of social economy from the society surronding Angke Kapuk Forest which influences indirectly to the condition of Angke Kapuk Forest where for nowadays its existence has really been not good.This purpose of this research is to know people participation surrounding Angke Kapuk Forest in order to support the existence of area management of Angke Kapuk Forest. Also, this research can be used as an input for decision makers in deciding to expand sustainable development which has environment perception. Beside that, it is hoped that it can increase added value for this forest itself and people surrounding it.This hypotheses of this research are stated below:Ho : low or high education level and people income will not influence people participation level to Angke Kapuk ForestHa: low or high education level and people income will influence people participation level to Angke Kapuk ForestMethod of this research is descriptive with type of this research is case study. To test the hypotheses above, it is used chi quadrate test signification by using statistical product and service solutions (SPSS) version 10.00. Data are collected from literature study, observation, and deep interview with use questionnaires to people surrounding Angke Kapuk Forest.The results and conclusion of this research are education and income level actullay are not influencing people participation level at surrounding Angke Kapuk Forest, so Ho is accepted. People at surrounding Angke Kapuk Forest both low and high education and income level is not influencing them to participate in Angke Kapuk Forest management.The suggestions of this research are:It is better to do an intensive guidance which involves people at surrounding forest, such as Karang Tanzna so people has responsible feel for environmental preservation and then people desires to participate. But this whole things need government and non-government organization role to support people at surrounding Angke Kapuk Forest to be participated.Number References : 31 (1978-2001"

"ABSTRAK Ekosistem perairan dan daratan di sepanjang jalur pantai utara Pulau Jawa membentuk ekosistem mangrove menjadi ekosistem yang kaya akan keanekaragaman hayati yang saling berinteraksi, salah satunya di Desa Pantai Bahagia yang berada di Kecamatan Muara Gembong Kabupaten Bekasi, Jawa Barat. Pada kenyataannya, dari tahun 1999 hingga 2014, hutan mangrove di desa ini terus mengalami degradasi karena faktor antropogenik, yakni konversi lahan mangrove menjadi tambak oleh masyarakat pesisir yang menyebabkan penggerusan pantai terus terjadi di kawasan ini, karena tidak adanya penghalang ombak, sehingga intrusi air laut menjadi tinggi dan terjadi banjir rob yang menyebabkan kerugian besar bagi warga yang sebagian besar memiliki mata pencarian sebagai petani tambak. Hasil penelitian ini menunjukkan bahwa kondisi mangrove di Desa Pantai Bahagia dikategorikan rusak parah dan kondisi biodiversitas yang rendah, sehingga urgensi untuk melakukan rehabilitasi tergolong tinggi. Hingga tahun 2018 sudah mulai muncul partisipasi masyarakat dalam merehabilitasi hutan mangrove, namun masih tergolong rendah dan belum dapat menandingi laju kerusakannya. Karenanya, dilakukan studi pada 30 masyarakat Desa Pantai Bahagia yang memiliki kepedulian dan tingkat partisipasi mengelola mangrove yang tinggi untuk menganalisis faktor-faktor yang dapat meningkatkan partisipasi masyarakat secara keseluruhan, serta menyusun strategi peningkatan partisipasi masyarakat dalam merehabilitasi mangrove Desa Pantai Bahagia.

ABSTRACT Aquatic and terrestrial ecosystems along the northern coastline of Java Island form a mangrove ecosystem into an ecosystem rich in interacting biodiversity, one of which is in Pantai Bahagia Village in Muara Gembong District, Bekasi Regency, West Java. In fact, from 1999 to 2014, mangrove forests in this village continued to experience degradation due to anthropogenic factors, namely the conversion of mangrove land into ponds by coastal communities which caused coastal erosion to continue to occur in this region, due to the absence of wave barriers, so that seawater intrusion became high and there was a tidal flood which caused huge losses for residents who mostly had livelihoods as pond farmers. The results of this study indicate that the mangrove conditions in Pantai Bahagia Village are categorized as severely damaged and have low biodiversity conditions, so the urgency to carry out rehabilitation is classified as high. Until 2018 community participation has begun to emerge in rehabilitating mangrove forests, but is still relatively low and has not been able to match the rate of damage. Therefore, a study was conducted on 30 Pantai Bahagia villagers who have a high level of care and participation in managing mangroves to analyze factors that can increase overall community participation, and develop strategies to increase community participation in rehabilitating mangrove Pantai Bahagia Village.

Research on the structure of macrozoobenthos communities in mangrove ecosystems has been conducted in Cilamaya Wetan, Karawang, West Java in May 2019. This study aims to determine the structure of macrozoobenthos community such as composition, density, diversity, flatness, flatness, dominance, and frequency of attendance. . Another goal is to determine the relationship between mangrove density and the density and diversity of macrozoobenthos in the area. Sampling was carried out by purposive sampling and using the quadratic transect method at three stations, namely Muara Baru Village, West Tangkolak Village, and East Tangkolak Village. This study found 16 types of macrozoobenthos and 7 types of mangrove with very dense density (0.23-0.32 ind / m2). The highest density of macrozoobenthos is in West Tangkolak Village (8 ind / m2) and the lowest in Muara Baru Village (2 ind / m2). The diversity of macrozoobenthos is relatively high in the village of West Tangkolak with an index of 1.58 and the village of East Tangkolak with an index of 2.05, while the diversity is relatively low in the village of Muara Baru with an index of 0.28. The distribution of macrozoobenthos is classified almost evenly in the Village of West Tangkolak and the Village of East Tangkolak with a trade index of 0.88 and 0.85 respectively, while it is distributed equally in the Muara Baru Village with a pride index of 0.59. Data shows that there are no species that dominate in the villages of West Tangkolak and East Tangkolak, except in Muara Baru Village. Palawanense Episesarma is macrozoobenthos which has the highest attendance frequency in Muara Baru Village with a frequency of 27.7%. Environmental parameters including temperature, pH, and salinity are considered normal categories for macrozoobenthos and mangrove life. The results showed that mangrove density was related to macrozoobenthos density and diversity."
