Penelitian dilakukan untuk mengetahui keragaman jenis mamalia di areal bernilai konservasi tinggi (NKT) di perkebunan sawit Sumatra.  Penelitian juga dilakukan untuk mengetahui menajemen areal NKT dalam menunjang keberadaan mamalia di dalamnya.  Penelitian variasi mamalia di area NKT dilakukan melalui analisis data sekunder dari hasil pemasangan kamera perangkap yang telah dipasang selama kurun waktu 2016-2018.  Hasil yang diperoleh selanjutnya dianalisis untuk mengetahui nilai keragaman dan kerapatannya.  Sementara itu, penelitian manajemen areal NKT dilakukan dengan metode wawancara.  Data yang diperoleh selanjutnya dijabarkan secara deskriptif.  Diketahui, manajemen areal NKT meliputi proses perencanaan, pengorganisasian, pengkoordinasian, dan pengontrolan sumber daya.  Berdasarkan hasil penelitian, terdapat 26 spesies mamalia dari 6 ordo yaitu Artiodactyla (6 spesies), Carnivora (11 spesies), Perissodactyla (1 spesies), Primata (5 spesies), Rodentia (7 spesies), dan Scandentia (1 spesies).  Secara umum, tingkat keanekaragaman jenis mamalia di kawasan konservasi tersebut berada dalam kategori sedang.  Terdapat beberapa mamalia yang mendominasi antara lain Macaca nemestrina, Sus scrofa, Sus barbatus, dan Muntiacus muntjak

ABSTRACT
The aim of this study is to know the diversity of mammals in the area of High Conservation Value (HCV) and to know the manajement of HCV area in oil palm of Sumatra.  The study of variety of mammalian species carried out through the analysis of secondary data from the results of the installation of camera traps that has a fitted over a period of 2016-2018. Of the results obtained next analyzed in order to its diversity and density.  Meanwhile, the study of HCV area management carried out through the interview. The data obtained next elaborated to a sort of descriptive set. It is known that the HCV management covering the planning, organizing, coordinating, and controlling process. Based on this study results, there are 26 species of mammals of the order of Artiodactyla (6), Carnivora (11), Perissodactyl (1), Primate (5), Rodentia (7), and Scandentia (1). The level of species diversity in HCV area is in medium category.  Based on index value evenness, there are several dominated mammalian species such as Macaca nemestrina, Sus scrofa, Sus barbatus, and Muntiacus muntjak.

Pengelolaan ekosistem lamun yang tepat perlu dilakukan untuk mencapai keberlanjutan. Pendekatan yang dapat digunakan yaitu jasa ekosistem. Tujuan riset ini adalah menganalisis struktur komunitas lamun, nilai ekonomi ekosistem lamun, serta persepsi pemangku kepentingan, penduduk, dan wisatawan. Penelitian dilakukan di pulau pemukiman di Kepulauan Seribu. Analisis yang digunakan yaitu analisis struktur komunitas lamun, analisis total nilai jasa ekosistem lamun, serta analisis deskriptif untuk menjelaskan persepsi masyarakat. Hasil riset menunjukkan bahwa ada enam jenis lamun yang ditemukan yaitu Syringodium isoetifolium, Halophila ovalis, Halodule uninervis, Cymodocea rotundata, Thalassia hemprichii, dan Enhalus acoroides. Tutupan lamun berkisar antara 13,16 – 58,87%. Densitas lamun 57,00-246,86 ind/m². Indeks diversitas 0,796-1,326, dan indeks dominansi 0,576-1,04. Status lamun di Kepulauan Seribu secara umum tergolong miskin. Total nilai ekonomi lamun di Kepulauan Seribu yaitu Rp21.501.460.102.547/tahun. Nilai ekonomi ekosistem lamun dipengaruhi oleh kondisi padang lamun. Ada perbedaan persepsi tentang ekosistem lamun antara pemangku kepentingan, penduduk, dan wisatawan. Perbedaan dipengaruhi oleh pengetahuan dan pengalaman yang dimiliki. ......The proper management of seagrass ecosystems needs to be done to achieve sustainability. The approach that can be used is ecosystem services. The purpose of this research is to analyze the structure of seagrass communities, the monetary value of seagrass ecosystems, as well as perceptions of stakeholders, residents and tourists. The research was conducted on residential islands in Kepulauan Seribu, Jakarta. The method used is analysis of seagrass community structure, analysis of the total value of seagrass ecosystem services, and comparing people's perceptions. Research shows that there are six types of seagrass found, namely Syringodium isoetifolium, Halophila ovalis, Halodule uninervis, Cymodocea rotundata, Thalassia hemprichii, and Enhalus acoroides. Seagrass cover ranges from 13.16 - 58.87%. Seagrass density 57.00-246.86 ind/m². Diversity index 0.796-1326, and dominance index 0.576-1.04. The status of seagrass in the Kepulauan Seribu is classified as poor. The total economic value of seagrass in the Kepulauan Seribu is IDR 21,501,460,102,547/year. The economic value of seagrass ecosystems is affected by seagrass conditions. There are differences in perceptions of seagrass ecosystems between stakeholders, residents, and tourists. Differences are affected by the knowledge and experience.

Fish fauna survey biodiversity was conducted in Ujung Kulon National Park, Pandeglang-West Java, to reveal fish diversity in mangrove ecosystem. Samples were caught using electrofish (12 V 10A), gill net (mesh sized 1-1.5 cm) and fishing tackle. Result showed that there were 58 fish species belongs to 34 families and 43 genera gobiidae was a dominant famili with 3 species. Cigenter river has highest diversity with H = 2.74, E=0.930, d = 5.346. Serinding fish (Ambassis dussumieri) was the highest abundance compared to others.

Penelitian ini menguji hubungan antara pertumbuhan ekonomi (PDRB per kapita) dan biodiversity loss di Indonesia. Hipotesis Kurva Kuznets Biodiversitas diinvestigasi dan diuji dengan data tahunan indeks kekayaan spesies dan PDRB per kapita dari tahun 2005 sampai dengan 2012 untuk 33 provinsi di Indonesia. Penelitian ini menghasilkan bahwa hubungan antara biodiversity loss dan pendapatan mengikuti kurva Kuznets atau membentuk kurva U terbalik. Hal ini berarti bahwa seiring dengan peningkatan pendapatan, biodiversity loss akan mengalami tren pennurunan dan kemudian meningkat kembali. Atau dengan kata lain, kekayaan spesies meningkat pertama, mencapai titik belok, dan kemudia menurun. Titik belok untuk penelitian ini berada pada tingkat Rp9,747,369.00 dari PDRB per kapita. ...... This research examines the relationship between economic growth (GRDP per capita) and biodiversity loss in Indonesia. The Biodiversity Kuznets Curve hypothesis is investigated and tested with the annual data of species richness index and GRDP per capita from 2005 - 2012 for 33 provinces in Indonesia. The research reveals that the relationship between biodiversity loss and income follows Kuznets curve or inverted U-shaped. It means that with increase in income, biodiversity loss first experiences a declining trend and then starts rising again. Or in other words, the species richness increases first, reaches a turning point, and then starts declining. A turning point for this research is at level Rp9,747,369.00 of GRDP per capita.
