Abstrak: TPA Cipayung has been operated since 1992, at Cipayung, Pancoran Mas, Kota Depok. To face the problem around TPA Cipayung, it is important to development management some analysis. The research purpose of this research were: 1) to explain environmental quality, social, economic and health condition around Cipayung garbage’s TPA area at Depok city. 2) to analyse policy strategy that related to effort of managemant of Cipayung garbage’s TPA at Depok city. 3) to design alternative policy of management of Cipayung garebage’s TPA at Depok city. The research methods used descriptive analysis to analyze the quality of up down wells, BAP, lindi water, and microbiology. Then, the results were compared with Permenkes RI No. 416/MenKes//Per/IX/1990, Kriteria Mutu Air PPRI No.28/2001. Gol. III, Baku Mutu: SK Gubernur Jawa Barat No. 6/1999. Sampel water analysis was conducted in laboratory of PT. Mutu Agung Lestari. The condition of social economy and health in location around of TPA Cipayung were analyzed by descriptive analyzed. Data of interview result with profesional about policy of management TPA Cipayung was analyzed with AHP method, using expert choice 2000 program. Analysis of garbage management model in TPA Cipayung using Microsoft Office Excel and Stimulation model analysis of dinamic system using Stella software vertion 8.0. The result of this analysis show the physical variabel of water quality in three location still under NAB that were permitted. Except the temperatur variabel have rather high than NAB. The result of many chemical variabel in three location sampel have high then NAB that permitted, such as Fe, Mn, NO2 -N, BOD5, COD, DO, Zn, and Fenol. The result of social economy aspect are there is some problems around TPA Cipayung and the benefiit of economy that TPA Cipayung’s society can get. Health of society in location around TPA Cipayung in general, suffering diare, fever, skin infection and ispa.The result of Analysis Hierarchy Process (AHP) showed that (1) alternative of policy is the optimalization of garbage management, (2) the optimalization of cleaning service, (3) third priority is the increase of stakeholder’s participation. (4) law enforcement. The result of garbage management strategy analisys in TPA Cipayung recomendation program 3R+1P, start from the garbage source, until the garbage that throw in to TPA getting low and can minimalize the garbage transportation cost to TPA.

Judul: SUSTAINABLE WASTE MANAGEMENT (Case Study: TPA Cipayung, Depok)
Abstrak: Kota Depok merupakan salah satu kota di Provinsi Jawa Barat dengan kepadatan penduduk yang tinggi. Tingkat konsumsi masyarakat perkotaan yang tinggi mengakibatkan volume sampah semakin meningkat, sehingga perlu strategi pengelolaan yang berkelanjutan agar TPA Cipayung dapat mengelola dan mengurangi volume sampah yang ada. Penelitian ini bertujuan untuk menganalisis persepsi masyarakat terhadap pengelolaan sampah di TPA Cipayung menggunakan metode analisis deskriptif dan skala Likert, menghitung estimasi kerugian ekonomi dengan menggunakan replacement cost dan cost of illness, dan menganalisis strategi pengelolaan yang berkelanjutan di TPA Cipayung menggunakan analisis SWOT. Hasil penelitian menunjukkan persepsi masyarakat terhadap pengelolaan sampah di TPA Cipayung dalam aspek ekonomi, sosial, dan lingkungan dinilai positif. Estimasi kerugian dengan rata-rata biaya mengganti air bersih yang dikeluarkan responden mencapai Rp.1.351.273,-/tahun sementara untuk biaya berobat sebesar Rp.60.416,-/tahun. Strategi yang dapat dilakukan oleh TPA Cipayung adalah mengembangkan program tentang pengelolaan sampah yang dilakukan secara berkala., Depok city is one of the most densely populated cities in West Java Province. The high level of consumption of urban residents results in increasing waste volumes. Therefore, a sustainable waste management strategy is needed for the Cipayung Landfill to manage and reduce the existing waste volume. This study aims to analyze public perception of waste management at the Cipayung Landfill using descriptive analysis and Likert scale methods, calculate economic loss estimates using replacement cost and cost of illness, and analyze sustainable waste management strategies at the Cipayung Landfill using SWOT analysis. The results show that public perception of waste management at the Cipayung Landfill in the economic, social, and environmental aspects is assessed positively. The estimated loss with an average cost of replacing clean water spent by respondents reached Rp.1,351,273.-/year while for medical costs it was Rp.60,416.-/year. Strategies that can be taken by the Cipayung Landfill are to develop programs on waste management that are carried out regularly.

Judul: Sintesis Nanorod Seng Oksida (ZnO) dengan Metode Sonokimia
Abstrak: Gelombang ultrasonik telah digunakan untuk membantu sintesis ZnO. ZnO terbentuk dari campuran ZnAc dan NaOH. ZnO disintesis dengan variasi konsentrasi ZnAc 0.5 M ( ZnO 1:1 ) dan 1.5 M ( ZnO 3:1 ) yang dicampurkan dengan NaOH konsentrasi 0.5 M. Sampel yang diporoleh dikarakterisasi dengan XRD dan SEM. Karakterisasi difraksi sinar-X menunjukkan bahwa struktur kristal ZnO yang dihasilkan merupakan heksagonal dengan pertumbuhan yang dominan pada orientasi bidang nonpolar a dengan indeks hkl 101. Kristalinitas dan kemurnian kristal ZnO 1:1 lebih baik dibandingkan ZnO 3:1 ditunjukan dengan intensitas puncak difraksi sinar-X yang lebih tinggi, sempit dan tajam. Untuk ukuran kristalit ZnO 1:1 mempunyai rata-rata ukuran kristalit 30.57 ± 4.31 nm sedangkan ZnO 3:1 mempunyai ukuran rata-rata 20.25 ± 7.12 nm. Dari ukuran kristal yang terbentuk partikel ZnO termasuk nanokristal. ZnO 1:1 terbentuk batang-batang nano (nanorods) sedangkan pada ZnO 3:1 tidak terbentuk batang-batang nano (nanorods). Untuk ukuran morfologi, ZnO 1:1 mempunyai rata-rata ukuran butiran kristal 230 nm dan lebih besar dibandingkan ukuran ZnO 3:1 yang mempunyai rata-rata ukuran butiran kristal 50 nm.
