Based on the results of observations of organic waste in the village of Jogotirto Berbah, Sleman, it is known that the amount of household organic waste and cow dung from 2015 to 2020 continues to increase by ± 12% per year. In Jogotirto, the average person produces 0.36 kg of organic waste per day and 15 kg of dry cow dung per day. In 2020 the amount of household organic waste is 8,477 kg per day, while for cow dung is 16,787.75 kg per day. Analysis of the study of the establishment of the organic fertilizer industry is carried out by processing household organic waste and solid cow dung by fermentation. This fermentation process is carried out anaerobically for 21 days. The organic fertilizer processing process is carried out by mixing cow dung and household waste with varying ratios. From the results of research on making organic fertilizer, it is known that a mixture of cow dung and household waste with a mixture ratio of 2: 1 contains nitrogen compounds as much as 1.04%, organic C 17.6%, phosphorus 1.7% and potassium as much as 7.02%. Based on the analysis of investment feasibility using the Net Present Value method, the fertilizer industry can generate a profit of 200.18% for 5 years. Analysts using the ROR method can provide a profit of 31.7% per year and the analysis using the pay back method is known that the period of capital will return after 3.85 years. Based on the sensitivity test of the fertilizer industry, it is still said to be safe for changes in influencing parameters, namely the sensitivity rate of 20%. This study of the establishment of the organic fertilizer industry aims to provide advice to the government in the context of improving the community's economy.

Waste has become a problem that is really worrying everywhere. If you pay close attention, there are indeed a number of factors that cause waste problems to become serious. First, population growth. Second, more and more instant food with plastic packaging. Third, the habit of littering, the habit of consuming instant food in packaging, to the habit of throwing garbage without sorting between organic and non-organic waste will damage the ecosystem. The same problem is also experienced by Berbek Village in Sidoarjo Regency, the problem of waste and flooding that is always faced by the city cannot only be the responsibility of the government, but the community as one of the producers of household waste should always help reduce the amount of waste. Thisneeds to provide an understanding to the community of environmental concerns, especially regarding household waste management and water conservation for the future based on water conservation. The results achieved from this activity are that the village community is aware of and understands the importance of a clean environment, there is no garbage scattered, puddles or floods can be reduced, and are able to practice independent waste management methods.

ABSTRAKSalah satu dampak dari proses pembangunan adalah pencemaran dan kerusakan lingkungan. Pertumbuhan penduduk yang pesat terutama di daerah perkotaan dengan perilaku membuang sampah yang tidak baik menyebabkan berbagai limbah yang harus diserap oleh lingkungan, terutama limbah domestik atau limbah rumah tangga. Komposisi sampah organik menempati persentase tertinggi hingga 57% di Kota Bandung, dimana limbah sisa makanan yang menempati urutan teratas yaitu sebesar 40%. Masyarakat dan pemerintah saja tidak cukup untuk mengatasi persoalan pengelolaan sampah. Keterlibatan dan partisipasi aktif perusahaan sebagai pihak swasta melalui kegiatan tanggung jawab sosial perusahaan dapat dilakukan melalui program-program yang mendukung pengolahan limbah organik berkelanjutan. Pengembangan program CSR yang baik pada suatu perusahaan sebaiknya dikaitakn dengan kebutuhan dan persoalan yang dihadapi masyarakat sekitar. Model Social Responsible Business Practice, merupakan salah satu jenis program yang bertujuan untuk mensejahterakan masyarakat, tapi juga memiliki korelasi positif dalam peningkatan produktivitas perusahaan secara operasional. Model praktik ini, memungkinkan aktivitas perusahaan yang salah satunya mencakup penyediaan fasilitas yang memenuhi tingkat keamanan dan keselamatan lingkungan dan dapat memelihara aktivitas pembangunan berkelanjutan. PT. Pertamina TBBM Bandung Group merupakan salah satu BUMN yang peduli dengan inovasi penanganan masalah sampah di Kota Bandung, melalui program BU MANIK (Budidaya Maggot dan Pupuk Organik), sejalan dengan program KANG PISMAN (Kurangi, Pisahkan, Manfaatkan) milik pemerintah Kota Bandung, yang bertujuan untuk membudidayakan maggot sebagai media utama pengurai limbah organik serta pakan ternak alami. Efektifitas program ini bergantung pada CSR PT. Pertamina TBBM Bandung Group sebagai lembaga yang memfasilitasi pelaksanaan program dan kelompok bank sampah sebagai komunitas yang diberdayakan, serta keterlibatan masyarakat dan dukungan pemerintah.Kata kunci: CSR, pengelolaan sampah, sumber daya berkelanjutan, pemberdayaan ABSTRACTOne of the impacts of the development process is environmental pollution and damage. Rapid population growth, especially in urban areas with bad waste disposal behavior, causes a variety of waste that must be absorbed by the environment, especially domestic waste or household waste. The composition of organic waste occupies the highest percentage up to 57% in the city of Bandung, where food waste that occupies the top rank is 40%. The community and the government alone are not enough to overcome the problem of waste management. The involvement and active participation of companies as private parties through corporate social responsibility activities can be done through programs that support sustainable organic waste treatment. The development of a good CSR program in a company should be related to the needs and problems faced by the surrounding community. Social Responsible Business Practice Model, is one type of program that aims to prosper the community, but also has a positive correlation in increasing company operational productivity. This practice model allows company activities, one of which includes the provision of facilities that meet the level of environmental security and safety and can maintain sustainable development activities.

     Insects have a vital role in solid waste composting process. Insects are detritus feeders that enhance changing the physical and chemical properties of decomposed materials during composting processes. This behavior makes insects excellent organisms in recycling of organic matter. The present study assesses the success of insects’ population in relation with the degradation of solid waste.  The study was carried out in the glass house facility of the College of Science, Salahaddin University in Erbil City, Kurdistan region of Iraq, using household organic waste. During composting process, three stages of lifecycle of insects were observed and recorded. The total number of insects reached to 1268 individuals, belonging to the orders Coleoptera and Diptera, class Insects. Diptera individuals were the most abundant insects with 95.4% of the total belonged to four families (Muscidae, Calliphoridae, Ulidiidae and Milichiidae). Coleoptera individuals represented 4.6% of the total number, belonging to three families (Promecheilidae, Staphylinidae and Salpingidae). The measured physicochemical characteristics of the compost included: pH, EC, moisture, total organic carbon, total nitrogen, total phosphorous and organic matter. The pH value of the composts ranged from 7.79 to 7.97. Organic carbon content and organic matter content ranged from 20.16 to 26.99 % and 34.67 to 46.23 %, respectively. It can concluded that household waste compost is not just a waste but has the potential to be transformed into a good quality organic fertilizer through composting. Composting can convert solid organic waste into a valuable added material.

In general, coastal areas have the physical and chemical properties of lessfertile land with an extreme dry climate, so that only a few plants that can live,including Jatropha curcas L. To enhance fertility and improve soil physicalproperties, need the addition of organic fertilizer. Source of compost canbe derived from a variety of wastes, including household waste and landfill.Quality compost landfill taken from Piyungan, Yogyakarta, has a high content of organic C, pH neutral, low N concentration, with the ratio C/N is very high. But compost landfill has an obstacle in the form of heavy metal containing high Cu and Pb. To prevent accumulation heavy metals into plant tissue or clean up heavy metals from the soil it was attempted by phytoremediation using jatropha plantation and bio-fertilizer that contains bacteria Azotobacter sp and Pseudomonas sp.From the research results can be informed that: (1) The city compost and biological fertilizers, can increase soil fertility with increasing nutrient content in soil. (2) Biofertilizers could inhibit the accumulation of copper (Cu) and lead (Pb) into Jatropha curcas L., (3)Jatropha plant can be classified as phytoremediation plants, because it can absorption heavy metals into leaf tissue.Key words: landfill compost , bio fertilizer, jatropha plants, heavy metals

Vermicomposting is an ecofriendly technology to convert organic waste into organic fertilizer. An epigenic species Eisenia fetida was used for the biotransformation of the banana pseudostem scutchers and cow dung into the vermicompost. Three different combinations of the banana pseudostem scutcher and cow dung were evaluated in the vermicomposting process. The change in the physicochemical parameters were examined by the standard method at the end of the vermicomposting. The results showed that earthworms increased the EC and NPK content while total carbon, pH and C:N ratio was reduced significantly in vermicompost of banana pseudostem scutchers. The maximum significant change in NPK content and reduction of total carbon and C:N ratio was found in the mixture of (75% banana pseudostem scutcher + 25% cow dung). The highest growth and reproduction rate was also present in the T2 treatment. The seed germination test was performed to evaluate the maturity of the vermicompost. The prepared vermicompost shows the significant effect on the growth of the Vigna radiata. The germination of the Vigna radiata is comparatively higher in vermicompost of the T2 treatment. It is evident from the results that the banana pseudostem scutcher and cow dung are good substrates for the vermicomposting and Eisenia fetida able to convert this organic waste into the stable nutrient rich product. This nutrient rich vermicompost has no phytotoxicity and the ratio of carbon/nitrogen below 15 which indicates the acceptable maturity and it can be utilize as organic fertilizer.

Abstrak-Pemanfaatan  sampah organik rumah tangga tiap tahun meningkat karena berbagai permasalahan yang akan timbul seperti polusi udara, dapat menimbulkan dampak penyakit dan bahaya banjir. Sampah yang dapat dimanfaatkan adalah sampah organik berupa sisa sayuran, sisa buah-buahan, sisa daun kering, dan ranting pohon. Sampah organik rumah tangga ini  paling banyak digunakan dalam kehidupan sehari-hari karena kebutuhan akan makanan sehingga kuantitasnya semakin banyak dihasilkan  dan akan menumpuk karena tanah tidak mampu mendegradasi dalam jumLah yang banyak, sehingga dapat merusak lingkungan berupa polusi udara (bau) dan serta dapat menyebabkan dampak penyakit. Seiring dengan dampak yang ditimbulkan maka sampah organik harus diolah dalam lingkungan rumah tangga terlebih dahulu dengan mengubahnya dalam bentuk yang lebih bermanfaat seperti pupuk cair organik. Pupuk cair lebih mudah diserap oleh tumbuhan dan dalam bentuk konsetrat sehingga lebih ekonomis karena dapat diencerkan. Penelitian ini bertujuan memanfaatkan sampah organik rumah tangga  menjadi  pupuk cair dan melihat pengaruh dari bioaktivator EM4 dan Promi terhadap pembuatan pupuk cair dari  kandungan C organik. Metode penelitian yang digunakan berupa bahan baku sampah sayuran berupa kangkung, sawi, bayam dan wortel serta daun kering sebanyak 300 g dibersihkan dan dipotong kecil-kecil kemudian dimasukkan di dalam komposter sebelum di fermentasi di basahkan atau dilembabkan dengan bioaktivator terlebih dahulu kemudian difermentasi selama 7 hari. Proses fermentasi dilakukan dengan variasi bioaktivator 2,5 mL, 5 mL, 7,5 mL, 10mL, dan 12,5 mL. Pupuk cair organik yang dihasilkan dengan menggunakan EM4 dan Promi dapat digunakan sebagai bioaktivator dalam penggunaan pupuk akan tetapi bioaktivator EM4 memberikan kerja yang lebih efektif dalam mengdegradasi sampah organik sehingga menghasilkan kadar C organik sekitar 23% dibanding  bioaktivator Promi sekitar 18% dan begitu juga kandungan senyawa  lain untuk EM4 seperti kadar nitrogen 3,8%, kadar P2O5 3,0% kadar K2O 4,2% sedangkan Promi kadar Nitrogen 3,2%, kadar P2O5 2,5% dan K2O 3,0%. Dari hasil analisa terlihat bahwa bioaktivator EM 4 menghasilkan pupuk cair  dengan C organik yang tinggi di bandingkan dengan Promi. Standar pupuk cair disesuaikan dengan Permentan No 11/2011, tetapi kedua bioaktivator ini bisa digunakan untuk pembuatan pupuk cair organik. Kata Kunci : sampah organik, EM4, promi, fermentasi Abstract- Utilization of household organic waste each year is increasing due to various problems will arise such as air pollution, can have an impact of the disease and the danger of flooding. Waste that can be used are organic waste such as leftover vegetables, fruits, leftover dried leaves and twigs. Household organic waste is the most widely used in daily life because of the need for food so that the quantity is more and more produced and will accumulate because the ground is not capable of degrading in significant amounts, so as to damage the environment in the form of air pollution (odor) and can cause impact disease.Along with the impact of the organic waste to be treated in a household environment prior to turning it into more useful forms such as liquid organic fertilizer. Liquid fertilizers are more easily absorbed by plants and in the form konsetrat so it is more economical because it can be diluted. This research aims to use household organic waste into liquid fertilizer and see the impact of bio-activator EM4 and Promi to manufacture liquid fertilizer from organic C content. The method used in the form of waste materials vegetables such as kale, mustard greens, spinach and carrots as well as dried leaves 300 g cleaned and cut into small pieces and then put in the composter before fermentation in lightly mist or moistened with a bio-activator before hand and then fermented for 7 days , The fermentation process is done with a variety of bio-activator 2.5 mL, 5 mL, 7.5 mL, 10 mL, and 12.5 mL. Organic liquid fertilizer produced by using EM4 and Promi can be used as a bio-activator in fertilizer use but bio-activator EM4 provide more effective work in mengdegradasi organic waste to produce high levels of organic C approximately 23% compared to bio-activator Compromise approximately 18% and so is the content of other compounds EM4 such as nitrogen for 3.8%, 3.0% P2O5 content of K2O content of 4.2% and 3.2% Compromise Nitrogen levels, levels of 2.5% P2O5 and 3.0% K2O. From the analysis shows that the bio-activator EM 4 produces organic liquid fertilizer with a high C in comparison with the Compromise. Standard liquid fertilizer tailored to Permentan No.11/2011, but both bio-activator can be used to manufacture organic liquid fertilizer. Keywords: Organic Waste ,, EM4, Compromise, Fermentation
