"ABSTRAK
Masyarakat seharusnya menjadi pihak utama dalam mengelola sumber daya alam karena peransertanya akan mempengaruhi kelangsungan sumber daya tersebut, balk secara Iangsung maupun tidak Iangsung. Sayangnya, banyak Peranserta yang tidak sejalan untuk mendukung kelestarian lingkungan dan cenderung mengarah kepada kerusakan ekosistem dan pencemaran lingkungan. Dalam penelitian ini, pengaruh Peranserta masyarakat yang tinggal di sempadan sungai Enim dan kondisi penanganan Iimbah terhadap pengelolaan kualitas sumber secara khusus dipertanyakan. Oleh karena itu, penelitian ini dilakukan untuk mengkaji seberapa besar pengaruh Peranserta masyarakat dan kondisi penanganan Iimbah terhadap pengelolaan sumber daya air.
Tujuan penelitian ini adalah untuk mengidentifikasi dan menganalisa (1) Peranserta masyarakat dan kondisi penanganan Iimbah yang dihasilkan dari kegiatan sehari-hari, (2) pengaruh Peranserta masyarakat terhadap pengelolaan kualitas air, (3) hubungan antara kondisi penanganan Iimbah dan kualitas air; (4) pengaruh Peranserta masyarakat dan kondisi penanganan Iimbah terhadap pengelolaan kualitas air, secara bersamaan (simultan). Penelitian deskriptif analitis yang menggunakan metode survey ini dilakukan di daerah sepanjang Sungai Enim, Kabupaten Muara Enim, Provinsi Sumatra Selatan. Ada 132 responden yang tinggal di pinggir sungai, diambil sebagai sampel yang kemudian dianalisa dengan menggunakan analisa korelasi dan regresi.
Hasil pemrosesan data statistik menunjukkan bahwa besamya pengaruh simultan Peranserta masyarakat (X1) dan kondisi penanganan limbah (X2) terhadap pengelolaan kualitas sumber daya air (Y) adalah 0,733 yang berarti cukup kuat. Sedangkan kontribusi simultan variabel X1 dan X2 terhadap Y is 73,3% or (Y)= R2 x 100% = 73.3% dan sisanya ditentukan oleh variabel lain. Lebih jauh lagi, naikturunnya pengelolaan kualitas sumber daya air dapat diprediksi atau dihitung melaiui persamaan regresi Y = 18.665 + 0.227 Xi + 0.459X2. Besarnya pengaruh variabel X1 terhadap Y adalah 0,685 atau 68,5%; kemudian, sisanya ditentukan oleh variabel lain. Besarnya koefisien pengaruh kondisi penanganan limbah terhadap pengelolaan sumber daya air adalah 0,566 atau kontribusi sebesar 56,6%.
Angka-angka di atas menunjukkan adanya korelasi yang besar antara (1) Peranserta masyarakat (X1) dan pengelolaan kualitas air (Y), (2) kondisi penanganan Iimbah (X2) dan pengelolaan kualitas air (Y), (3) Peranserta masyarakat (X1) bersamaan dengan kondisi penanganan limbah (X2) terhadap pengelolaan kualitas sumber daya air (Y). Dengan kata lain, masing-masing variabel (XI dan X2) saling mempengaruhi terhadap pengelolaan kualitas air baik secara individu maupun bersamaan.
Dari hal tersebut, penelitian ini menunjukkan bahwa Peranserta masyarakat dan kondisi penanganan limbah harus diperhatikan untuk meningkatkan pengelolaan sumber daya air. Hal tersebut dapat dilakukan dengan cara mendorong Peranserta masyarakat untuk ramah lingkungan dan menciptakan kondisi yang lebih balk dalam penanganan limbah. Ini memerlukan usaha-usaha strategis dan terpadu untuk menciptakan kondisi yang mendukung masyarakat memiliki Peranserta yang diinginkan dan ramah pada lingkungan. Berdasarkan kesimpulan di atas, penelitian ini merekomendasikan pemerintah daerah untuk berupaya mengubah Peranserta masyarakat dengan meningkatkan pengetahuan dan kesadaran akan pentingnya menjaga keberlangsungan lingkungan. Hal ini tentunya akan menghasilkan keuntungan yang akan meningkatkan kualitas hidup masyarakat pada umumnya dan generasi mendatang dalam jangka panjang. Dalam prakteknya, masyarakat harus diberikan pelatihan khusus dan penyuluhan mengenai cara penangangan limbah yang lebih baik. Terakhir, penyediaan prasarana yang relevan dan insentif yang nyata juga panting diberikan.

ABSTRACT
Society should be the main agent in managing natural resources, as their participation will influence the natural resources' sustainability, directly or indirectly. Unfortunately, many of the participations are not in line to support the environment preservation so that their daily activities often produce pollutions. The same thing happens to Enim River. In this research, the influence of participation of the society living on the riverside of Enim and the waste processing condition to water resource management in specific is questioned. Therefore, this research is to study how much the effect of society's participation and waste-processing condition to the quality of water resource management is.
The purposes of the research are to identify and analyze (1) the society's participation and the condition of waste processing resulted from daily activities; (2) the influence of society's participation on water quality management; (3) the relations between waste processing condition and water quality; (4) the influence of society's participation and waste processing condition on water quality management, simultaneously. This analytical descriptive research, which uses survey method, was conducted in the riverside of Enim Lematang River, District of Muara Enim, Province of South Sumatra. There are 132 respondents living on the riverbanks taken as samples, which later analyzed by using correlation coefficient and regression.
The statistical data processing result shows that the coefficient of simultaneous effect of the society's participation (X1) and the condition of waste processing (X2) to the management of water resource quality (Y) is 0.733, which means relatively strong. While the simultaneous contribution of variable XI and X2to (Y) = R2 x 100% = 73.3% and the rest is decided by other variables_ Furthermore, the fluctuation of the management of water resource quality can be estimated through the regression equivalence of Y = 18.665 + 0.227 XI + 0.459X2. The effect coefficient of variable Xl to Y is 0.685 or 68.5% in percentage; later, the rest is determined by other variables. The effect coefficient of waste processing condition to water resource management is 0.566 or contribution as of 56.6% in percentage. Those figures can be interpreted that there are considerable correlations between (1) the society's participation (XI) and water resource management (Y); (2) waste processing condition (X2) and water resource management (Y); (3) the society's participation (X1) together with waste processing condition (X2) and the water resource management (Y). In other words, those variables (Xiand X2) influence the water resource management, either solely or simultaneously.
The research shows that the society's participation and waste processing condition should be paid attention to promote the water resource management. It can be done by encouraging the people's participation to be friendly-environment and creating the better condition of waste processing. The findings of the research support the conclusion that the better transformation of society's participation promotes the success and effectiveness of the water resource management. It needs strategic and comprehensive efforts to create conditions, which favor the society to have desirable and friendly-environmental participations.
Based on the above conclusion, this research recommends the local government to attempt to transform the people's participation to increase their knowledge and awareness of the importance of keeping the environmental sustainability. It surely leads to the benefits, which will promote the life quality of the society in general, and the next generation for the long term. To put it into practice, the local government should give special training and counseling to the society on how to process waste better. The measures are expected to change the people's participation to treat the environment better. In addition, the government should also provide the relevant facilities or infrastructures and real incentives to the society."

"[ABSTRAK
Perkembangan ekonomi dan pertumbuhan penduduk suatu kota, menyebabkan permintaan akan pelayanan prasarana perkotaan meningkat pula, seperti pembangunan jalan raya, penyediaan kawasan permukiman dan pusat-pusat pelayanan umum, seperti tempat-tempat perdagangan, perkantoran, rumah sakit, sekolah dan lain-lain.
Hal ini akan mengubah sifat permukaan tanah yang sebelumnya dapat meresapkan air, menjadi sukar/tidak dapat meresapkan air, sehigga volume limpasan hujan akan bertambah besar. Karena sistem drainase kota yang kurang baik serta badan air penerima, seperti sungai dan waduk sudah terlewati daya tampungnya, maka limpasan hujan tadi menjadi penyebab terjadinya banjir di kawasan tersebut.
Secara konvensional konsep pengelolaan limpasan hujan pada suatu kawasan perkotaan berdasarkan pada gagasan bagaimana mengalirkan limpasan hujan secepat mungkin keluar dari kawasan tersebut langsung ke badan air penerima. Untuk mengatasi masalah limpasan hujan, dapat diterapkan konsep pengembangan lahan berwawasan lingkungan melalui pendekatan inovatif berbasis ekosistem yang dikenal sebagai konsep “Low Impact Development (LID)” yaitu pengembangan suatu sistem pengelolaan yang memperkecil laju dan volume limpasan hujan untuk menahan dan memperlambat aliran limpasan hujan masuk kebadan air, sekaligus memberi kesempatan air meresap kedalam tanah sebagai salah satu cara untuk pengisian kembali air tanah, tanpa menyebabkan timbulnya genangan/banjir pada kawasan tersebut
Dalam rangka pengelolaan limpasan hujan dan pelestarian sumberdaya air, Pemerintah Propinsi DKI Jakarta telah menerbitkan Keputusan Gubernur Kepala Daerah Khusus Ibukota Jakarta, Nomor 115 Tahun 2001, Tentang Pembuatan Sumur Resapan di Propinsi Daerah Khusus Ibukota Jakarta. Namun sejak Perda tersebut diundangkan, pelaksanaan peraturan belum berjalan dengan baik.
Untuk menanggapi masalah ini, dilakukan penelitian dengan tujuan: (a)
untuk mengetahui tingkat peranserta masyarakat dan pihak-pihak yang terkait lainnya (stakeholders) dalam kegiatan pengelolaan limpasan hujan, (b) memberikan masukan kepada Pemeritah/Pemerintah Daerah dalam pengambilan keputusan tentang pengelolaan limpasan hujan yang ideal dengan pendekatan yang berbasis peran serta masyarakat
Penelitian dilakukan dengan pendekatan metode “Stakeholders Analysis” (World Bank 1998), untuk mengetahui partisipasi ideal stakeholder dalam kegiatan pembuatan sumur resapan tersebut, sehingga akan diperoleh pemetaan strategi partisipasi dari setiap kelompok stakeholder. Hasil pemetaan ini akan dibandingkan dengan pelaksanaan aktual di lapangan, dengan studi kasus di kelurahan Duren Sawit dan Pondok Kopi, kecamatan Duren Sawit, Kotamadya Jakarta Timur.
Metode penelitian yang digunakan adalah metode survei, dengan sifat penelitian deskriptif analitik. Pengambilan data dilakukan melalui kuesioner dan wawancara, observasi dan studi literatur. Analisis data dilakukan secara kuantitatif dan kualitatif untuk kelompok-kelompok stakeholder.
Dari perbandingan tingkat partisipasi ideal dan partisipasi aktual (hasil penelitian) dari setiap kelompok stakehoder, dapat diambil kesimpulan bahwa:
1. Usaha-usaha Pemerintah Propinsi DKI Jakarta dalam mensosialisasikan Keputusan Gubernur DKI Jakarta, Nomor 115, Tahun 2001 belum maksimal, sehingga sebagian besar masyarakat tidak mengetahui tentang adanya Perda tersebut.
2. Tingkat kesadaran dan peranserta/partisipasi masyarakat sangat kurang dalam mewujudkan usaha-usaha Pemerintah DKI Jakarta dalam pengelolaan limpasan hujan dalam rangka penanggulangan banjir dan pelestarian sumberdaya air, karena Pemerintah (DKI Jakarta) tidak optimal menjelaskan maksud dan tujuan PLH kepada masyarakat, dan tidak optimal pula dalam pengawasan terhadap pelaksanaan pembuatan sumur resapan, sehingga terjadi ketidak patuhan masyarakat terhadap peraturan tersebut, walaupun mereka sebagian besar dari golongan menengah keatas, berpendidikan cukup tinggi, dan dengan status tempat tinggal milik sendiri.
Kesimpulan diatas memperlihatkan bahwa implementasi dari Keputusan Gubernur Kepala Daerah Khusus Ibukota Jakarta, Nomor 115 Tahun 2001, Tentang Pembuatan Sumur Resapan di Propinsi Daerah Khusus Ibukota Jakarta, sampai saat ini belum berjalan dengan baik.

ABSTRACT
The economic development and the population growth of a city lead to the increasing demand for public services such as new roads, settlement areas, trade centers, office buildings, hospitals and schools. However, this, in the long run will affect the ground surface condition and change from pervious to impervious surface, the condition which will cause increasing volume of surface run-off and higher flood potential. The condition of over capacity of the rivers and reservoirs and poor drainage system of the city contributes to flood occurrence.
The concept of conventional stormwater management is based on the idea of draining the water from the affected area in the quickest manner to the recipient water body.
To overcome the run-off problem, an innovative, sustainable ecosystem- based approach for land development and run-off management, known as “Low Impact Development (LID)” concept is to be adopted. The basic idea of the concept is to detain and slow down the flow of run-off entering the water body, giving time for the water to infiltrate into the ground and recharge the ground water without flooding the area.
Within the framework of run-off management and water resources reservation, the Provincial Government of DKI Jakarta has issued the Decree of Governor of DKI Jakarta, Number 115 Year 2001, on the Making of Infiltration-Well in the Province of DKI Jakarta. This, however, has not been successfully implemented.
The purpose of the present research is therefore (a) to know the level of participation of stakeholders in run-off management activity, (b) to advise the government on the ideal community-based participation run-off management.
The present research is carried out by applying the “Stakeholders Analysis” (World Bank, 1998) approach to obtain the stakeholders level of participation and the strategic mapping of participation in the making of infiltration-well. Analysis is made by making comparison between the mapping and the actual activity in case study areas in Kelurahan Duren Sawit and Pondok Kopi, Kecamatan Duren Sawit, East Jakarta.
A field survey is conducted and a further descriptive analysis is utilized. Data collection is carried out through interviews and questionnaires, observations and literature studies. Data is then analysed quantitatively and qualitatively for individual groups of stakeholders.
Based on the comparisons made between the ideal level of participation and the actual participation of each stakeholder group, conclusions can be drawn
as follow:
1 The Provincial Government of DKI Jakarta has not made maximum efforts in promoting the Decision of the Governor of DKI Jakarta
Number 115 Year 2001 which has resulted in the limited number of community members who recognize the regulations.
2. The community level of awareness and participation in the implementation of the DKI Jakarta Provincial Government efforts in the run-off management and water resources reservations is low. This is due to the failure of the government to inform the community the purposes and aims of the PLH, as well as the inadequate and weak monitoring of the making of infiltration wells by the community members. The above conclusions indicate that the Decision of The Local Government of DKI Jakarta Number 115 Year 2001 on The making of Infiltration Well in the province of Jakarta has not been well implemented and executed.

"Laju pertumbuhan penduduk yang tinggi menyebabkan tutupan lahan pada suatu daerah akan semakin besar. Pada tahun 2017, presentase lahan yang sudah terbangun di DTA UI pada bagian luar kamus UI Depok mencapai 95 dan pada bagian dalam kampus UI mencapai 20 yang selalu bertambah setiap tahunnya. Hal ini menyebabkan terjadinya peningkatan volume limpasan permukaan. LID adalah salah satu metode untuk mengelola limpasan hujan untuk kawasan skala mikro. Bangunan LID dirancang untuk mengelola hujan dengan spektrum ringan sampai sedang. Salah satu alat yang dapat mensimulasikan peletakan bangunan LID adalah BMP Siting tool. Penelitian terdahulu sudah menghasilkan suatu usulan terapan berbagai bangunan LID-BMP di DTA UI Depok dengan menggunakan bantuan BMP Siting Tools.
Pada penelitian ini bertujuan untuk membandingkan volume limpasan permukaan tanpa dan dengan adanya bangunan LID pada DTA UI Depok serta menghitung efektifitas bangunan LID untuk berbagai spektrum hujan. Dengan menghitung nilai CN yang terjadi akibat adanya perubahan tata guna lahan setelah penerapan bangunan berkonsep LID di DTA Kampus UI Depok maka akan mempengaruhi besar volume limpasan di DTA tersebut.
Bangunan berkonsep LID yang digunakan adalah bioretention, porous pavement, infiltration trench, infiltration basin, vegetated filterstrip, sand filter nonsurface, sand filter surface, rain barrel dan grassed swales. Sand filter merupakan bangunan termudah dan terbanyak yang dapat dibangun di DTA UI menurut BMP Siting Tools. Efektifitas penurunan volume limpasan setelah peletakkan bangunan LID-BMP terhadap kondisi eksisting bervariasi dari 3-30 dengan efektifitas terbesar menggunakan teknologi sand filter surface/nonsurface.

High population growth rate will increased the impervious land cover in a certain area will be greater. In 2016, the percentage of impervious area in DTA UI Depok has reached 95 on the outside Campus UI and on the inside reaches 20 which is always increasing every year. This condition causes the surface runoff volume will increase. LID is a new paradigm for stormwater management in micro scale areas. LID infrastructure is designed to manage stormwater for light to moderate rainfall spectrum. Previous research has produced an applied proposal of various LID BMP infrastructure in UI catchment area, Depok, by using BMP Siting Tools.
This study aims to compare the volume of surface runoff without and with the LID infrastructures on UI catchment area, Depok, and to calculate the effectiveness of LID infrastructure for various spectrum of rainfall. By calculating the CN value that occurs due to the change of land use after the implementation of LID concept building in DTA UI Depok Campus it will affect the volume of runoff at the DTA.
The LID infrastructures used are bioretention, porous pavement, infiltration trench, infiltration basin, vegetated filterstrip, nonsurface sand filter, sand filter surface, rain barrel, green roof and grassed swales. By applying said infrastructures, the reduction of peak flow on various rain spectrums various from 3 30 with the greatest effectiveness using sand filter surface nonsurface technology.

"Skripsi ini membahas tentang perkiraan perubahan parameter hidrologis (nilai CN dan Tc) di Kampus Universitas Indonesia Depok akibat adanya rencana pengembangan lingkungan kampus yang mengubah beberapa area hijau pada tahun 2010 menjadi kawasan terbangun pada tahun 2025. Untuk studi ini, daerah tangkapan air Kampus UI Depok dibagi menjadi 12 sub-area dimana 5 di antaranya ditentukan sebagai sub-area prioritas karena rasio perubahan tata guna lahannya yang relatif tinggi. Masing-masing karakteristik tata guna lahan setiap sub-area dimodelkan bentuk hidrograf limpasan dan parameter hidrologisnya (debit puncak, volume limpasan, dan tinggi limpasan) menggunakan metode SCS TR-20 dengan kurva massa hujan FDOT 4-hour dan hidrograf satuan Standar SCS dibantu aplikasi HydroCAD v8.50.
Pendekatan low-impact development (LID) adalah untuk meniru kondisi hidrologis pascapembangunan seperti kondisi prapembangunan. Penelitian ini mengasumsikan bahwa kondisi pascapembangunan adalah saat terbangunnya Kampus UI sesuai Rencana Induk tahun 2025, sementara kondisi eksisting pada tahun 2010 sebagai kondisi prapembangunan. Selisih volume dari kedua kondisi tersebut dapat dijadikan dasar perancangan teknik pengendalian limpasan berbasis LID seperti bioretensi, buffer/filter strip, saluran berumput, tong hujan, dan tangki hujan. Praktik LID yang biasa disebut sebagai best management practices (BMPs) ini direncanakan akan dipasang pada sub-area prioritas tersebut pada kondisi tahun 2025; dan kondisi ini selanjutnya dimodelkan kembali untuk diketahui kondisi hidrologisnya. Perubahan yang terjadi diperbandingkan dan dianalisis dan dapat digunakan sebagai dasar menentukan rekomendasi bersamaan dengan implementasi rencana induk tersebut.
Akibat perubahan nilai CN dan Tc, bentuk hidrograf akan berubah. Pada area terbangun, peningkatan CN dan pemendekan Tc menghasilkan debit puncak yang lebih tinggi dan volume limpasan yang lebih besar. Hasil penelitian ini menunjukkan bahwa BMP yang terpasang pada sub-area ternyata mampu menurunkan debit puncak maupun volume limpasan. Bentuk hidrograf limpasan pada kondisi tahun 2025 dengan penerapan BMP relatif mendekati bentuk hidrograf untuk kondisi prapembangunan pada tahun 2010.

This undergraduate thesis estimated the changes of hydrological parameters (CN and Tc) at the Universitas Indonesia Campus at Depok as a result of the campus development plan that would alter some of the green areas in 2010 to developed areas in 2025. The catchment of campus area is divided into 12-subcatchments where there are chosen 5 priority subcatchments based on the highest development areas. Characteristic of each land-use subcatchment is modeled by HydroCAD v8.50 using SCS TR-20 method with FDOT 4-hour rainfall mass curve and standard SCS-UH for routing the flood hydrographs which describe the peak discharge, volume, and the depth of runoff on subcatchments.
The low-impact development (LID) approach is to mimic the hydrological conditions of post-development into pre-development. This study set the post-development condition based on the UI?s 2025 Master Plan whereas the pre-development established as the existing year of 2010. The difference of the runoff volume can be used as a basis for designing runoff control techniques based on LID such bioretention, buffer/filter strips, grassed swale, rain barrel, and cistern. The application of LID techniques as commonly referred to best management practices (BMPs) are planned to be installed in the priority subcatchments. Thus, on these priority subcatchments are modeled using the installed BMPs design for year of 2025 condition. The changes are compared and then analyzed for yielding recommendations for the implementation of the Master Plan.
Due to the change of CN values and Tc, the hydrograph shapes transformed. In the developed areas, increasing of CN and shortening of Tc resulted in higher runoff peak discharge and bigger runoff volume. The installed BMP promotes to lower peak discharge and lesser volume as shown by this study. The results are showed by the hydrographs of the 2025 with installed BMPs which is attempting to the 2010.
