Abstract

Food waste can be meat, fish, cooked food scraps, moldy bread, bone scraps, cakes, expired foods, dairy products, fruits and vegetables. Food waste which is put into the trash will decay and produce a foul odor which in turn will invite flies and cause potentially diseases. Most of the food waste that is processed using the composting process needs to spend a relatively long time, which is about 1-3 months or even 6-12 months. This study aims to accelerate composting time through the addition of additive microorganisms in various quantities. Four aerobic composter reactors were utilized in this study. Variations of additive microorganisms added to the research object were 0 in reactor (control), 8 g in B2 reactor, 16 g in B3 reactor, and 32 g in B4 reactor. All reactors were added with dolomite lime. During the composting process temperature, pH, water content and macroelement were tested. The results showed that the mature and stable compost was reached on the seventh day and produced from B2 reactor. In That reactor treated food waste and additive microorganisms with a ratio of 7:3, and 1 g dolomite lime. The level of C/N ratio produced from B2 reactor was 16.71. The value of C/N ratio was better than B3 reactor which produced C/N of 18.37. The control reactor produced a C/N ratio of 21.84 and mature and stable compost was reached on the 14th day. All in all, this study was regarded to be successful in accelerating the degradation of food waste into mature and stable compost in just seven days.

Abstract

Kegiatan pengelolaan sampah dapat melepaskan gas rumah kaca (GRK) ke atmosfer dan mengintensifkan iklim global. Pengomposan adalah proses komponen aerobik karbon degradable organik dalam limbah diubah menjadi karbon dioksida. Menggabungkan prakompos dan vermicomposting berpotensi menimbulkan emisi amonia dan gas rumah kaca. Desain percobaan dilakukan dengan memberikan fermentasi kotoran kambing dalam vermicomposting sampah organik dengan jumlah yang berbeda untuk mengetahui pengaruh fermentasi kotoran kambing terhadap emisi gas CO2, CH4, N2O saat kematangan kompos. Desain penelitian ini menggunakan 4 kombinasi yaitu kombinasi pertama 80% sampah organik, 20% kotoran kambing; kombinasi kedua yaitu 80% sampah organik, 20% kotoran kambing, 100 mL Aspergilus niger; kombinasi ketiga yaitu 60% sampah organik, 40% kotoran kambing; dan kombinasi keempat yaitu 60% sampah organik, 40% kotoran kambing, 100 mL Aspergilus niger. Kriteria pengujian yang digunakan adalah pengujian emisi gas CO2, CH4, N2O di akhir kematangan kompos. Dengan adanya penambahan kotoran kambing, semakin banyak kotoran kambing ditambahkan emisi gas CO2, CH4dan NO semakin banyak. Sedangkan dengan ditambahkan Aspergillus niger, proses fermentasi semakin cepat dalam menghasilkan emisi gas CO2, CH4 dan N2O.

Abstract

Every industry has a potential to pruduce waste from its production processes. Waste defined as  unused material  coming  from  the  production  activity.  Type  of  industrial  waste  may  vary depend on production activity, such as raw material, type  of processes, including type of raw material used, machinary, which will influence the characteristic of waste itself. Pharmaceutical industry, within their production activity will produce waste which may be potential for harming the environment. The waste may in form of toxic or non toxic chemical substances in both solid or liquid waste. Most of the waste characterize as hazardous waste and need further treatment due to avoid environmental hazard. Hazardous waste from pharmaceutical industry are in form of sludge from waste water treatment plant (WWTP), rejected material and also used container.

Abstract

Solid waste management on Nusa Penida Island is one of the problems in tourism in Bali Province. To deal with this issue, the government has implemented various policies, where the policy that becomes an essential issue is the processing of energy waste. To support this, it is necessary to study the potential of waste characteristics on the island of Nusa Penida. This study aims to analyse the characteristics of waste on the island of Nusa Penida as an energy source based on the generation and composition of waste. Solid waste generation and composition were measured based on land and marine debris data. The total waste generation on land and marine debris can reach 6364.4 kg/day and 762.8 kg/day, respectively. The waste composition materials consist of masks, plastics, metals, and biodegradable organics with a value of 4.12%, 32.77%, 19.54%, and 43.57%, respectively. Therefore, the potential use of organic biodegradable as solid fuel can reach 51,933.8 MJ/day or 14,426 kWh/day. However, in the thermogravimetric analysis (TGA) test, the residue was 18.6%.

Abstract

GI dan EC digunakan untuk menyatakan toksisitas suatu zat. Sedangkan DOM digunakan untuk menyatakan biodegradabilitas suatu zat. Pada penelitian ini, GI, EC, dan DOM digunakan secara bersamaan untuk menentukan kompos matang dan stabil. Kompos matang adalah kompos yang telah hilang senyawa fitotoksinnya selama proses pengomposan. Kompos stabil adalah kompos yang tidak lagi menunjukan aktivitas mikroorganisme. Kompos yang diperkaya nilai N dengan penambahan pupuk anorganik seperti urea dan ZA, dapat berubah toksisitas dan biodegradabilitasnya. Nilai EC didapatkan dari pengujian toksisitas akut dan nilai GI dihasilkan dari uji indeks perkecambahan. Tujuan dari penelitian ini adalah untuk menentukan kompos matang dan stabil diperkaya berdasarkan nilai EC GI dan DOM kompos. Uji toksisitas akut dan uji indeks perkecambahan dilakukan dengan cara mengamati pertumbuhan benih kacang hijau selama 72 jam dengan variasi konsentrasi penambahan pupuk anorganik pada kompos. Sedangkan, DOM dinyatakan dalam rasio BOD5/COD. Selanjutnya hasil nilai EC, GI, dan rasio BOD5/COD dapat digunakan untuk menentukan kompos matang dan stabil diperkaya. Berdasarkan hasil penelitian, didapatkan bahwa kompos merek A telah matang dan stabil pada konsentrasi penambahan ZA sebesar 1,65% dan 0,41% penambahan urea , sedangkan kompos B telah matang dan stabil pada konsentrasi penambahan ZA sebesar 0,732% dan 0,2% penambahan urea.

Abstract

Jumlah penduduk yang meningkat juga meningkatkan jumlah kebutuhan energi. Namun, sumber daya yang tersedia juga semakin berkurang. Sehingga perlu digantikan dengan energi yang baru. Sampah yang meningkat dan pengolahan yang sangat sedikit dapat dijadikan sumber energi yang baru bagi masyarakat dengan konsep waste to energy (WTE). Salah satunya yaitu dengan mengubah sampah menjadi bahan baku RDF (refuse-derived fuel). RDF merupakan salah satu teknik penanganan sampah dengan mengubah sampah menjadi sesuatu yang bermanfaat yaitu bahan bakar. Sampah sangat berpotensi menjadi bahan baku RDF terutama organik dan plastik sebagai sampah yang mudah terbakar (combustible). Sampah tersebut dapat dimanfaatkan menjadi bahan baku RDF dengan cara menganalisis nilai kalor yang dihasilkan. Untuk menganalisis nilai kalor pada sampah combustible zona aktif II TPA Jatibarang dapat dilakukan dengan cara pengujian sampel sebanyak 100 gram dengan alat bom kalorimeter. Sampel tersebut diambil pada kedalaman 0-3 m dengan metode random sampling. Kemudian akan didapat nilai kalor tinggi yang dihasilkan sampel tersebut. Nilai Kalor Tinggi yang dihasilkan sampel tersebut sebesar 5,69 kkal/ton pada kedalaman 0-1 m, 6,07 kkal/ton pada kedalaman 1-2 m dan 5,94 kkal/ton pada kedalaman 2-3 m. Nilai kalor tinggi yang dihasilkan sampah combustible tersebut menunjukkan bahwa semakin rendah kedalaman sampah maka akan semakin tinggi nilai kalor yang dihasilkan dan sampah tersebut berpotensi sebagai bahan baku RDF.
