Residents and the government of Babakan Village have had difficulty managing their waste since the closure of the Babakan landfill several years ago. This study aims to formulate the concept of waste management in the Babakan Village, Bandung Regency, considering the waste generation and the characteristics of the residents. Data on the waste generation was obtained by sampling in several houses, while data on the characteristics of citizens was collected by distributing questionnaires. Based on the data gathered, it was found that the average waste generation per person per day in the Babakan Village was 0.134 kg with the composition of organic waste dominating up to 70.5%, while inorganic as much as 29.5%. The dominant types of waste in inorganic waste groups are plastic. In general, respondents have a good level of knowledge about waste. The enthusiasm of the community is high in participating to manage the waste with the 3R programs, such as recycling and operation of waste banks. With these data, the planning of handling of organic waste is done by a simple composter and biopori cylindrical water absorption hole, while handling inorganic waste can be done by operating a waste bank system.
Kegiatan yang melibatkan sanitasi di pondok pesantren merupakan hal yang harus diperhatikan agar kualitas kesehatan dan lingkungan tersebut tetap terjaga dengan baik. Salah satu pondok pesantren yang memiliki santri relatif banyak di Bandung adalah Tahfidz Qur’an Madrasah Tsanawihyah (MTS) Assalam. Pemeliharaan kesehatan dan lingkungan di MTS Assalam harus disertai dengan perencanaan dengan fasilitas kesehatan yang baik. Kajian ini dilakukan untuk merencanakan fasilitas sanitasi berdasarkan persepsi santri di Pondok Pesantren Tahfidz Qur’an MTS Assalam, Kota Bandung. Metode yang digunakan adalah menyebarkan kuisioner terhadap responden, yaitu santri, berjumlah 72 orang. Hasil survey ini memperlihatkan bahwa dominasi persepsi santri (71%) terhadap fasilitas penanganan air limbah tergolong resiko sedang, terhadap drainase paling dominan (50%) tergolong resiko rendah, terhadap pengelolaan sampah dominan (55%) tergolong resiko sedang. Secara keseluruhan, dominasi persepsi santri sebanyak 71% menggolongkan fasilitas sanitasi pada resiko sedang. Dari persepsi tersebut, maka dapat disimpulkan bahwa perlu ditingkatkan kondisi sanitasi di Pondok Pesantren Tahfidz Qur’an MTS Assalam dengan merencanakan fasilitasnya dengan baik secara kuantitas dan kualitas.
This study was conducted to see the effect of size and freshness variations of organic waste on BSF growth. The research was conducted on laboratory-scale research at campus of Pasundan University and field-scale research on Pojok Kang Pisman at Bandung City-hall. In laboratory-scale research, the organic waste used is artificial organic waste whose composition is close to organic waste from market. Meanwhile in field-scale research, the organic waste used is from market organic waste. Variations in pretreatment were carried out by varying the organic waste size and freshness in laboratory-scale research and comparison in order of chopping and fermentation of organic waste in various cocopeat thickness in field-scale research. Maggot/BSF growth analysis was carried out by calculating the waste reduction index, Efficiency of Conversion Digested Feed, survival rate, and maggot protein tests. The results of the laboratory study showed that the smaller the size of the waste influenced increasing the WRI, SR and ECD values but had little effect on the protein content of the larvae. The protein content of larvae is suitable for chicken feed (19-21%). However, when the waste was fermented, there was a significant increase in WRI and SR, and the protein content of the larvae increased (32-34%), suitable for tilapia and catfish feed. Field research results with higher larval density in fermented waste resulted in higher WRI and ECD values compared to laboratory results with lower larval density. In addition, the treatment of chop-fermentation and fermentation-chopped sequences gave different water content values which affected the WRI and ECD values. The higher the water content, the lower the WRI and ECD values. The protein content of larvae in the field study was almost the same as in the laboratory study, ranging from (31-34%).
The natural composting process takes a long time because it goes through four phases of temperature levels. One of them is the thermophilic phase, where the largest rate of organic degradation occurs. The purpose of this study is to accelerate the composting process through temperature control. It was carried out using the Continuous Thermophilic Composting (CTC) method. The heating system was designed to provide the thermophilic temperature in the range of 50 - 65 °C. Arduino microcontroller was used to control the process temperature in real time. Several experiments were carried out to obtain the best design. In the first experiment, acrylic was used as the heating system wall with a 100 W incandescent lamp and a fan. The highest composting temperature produced was 38 °C on the 7th day. In the second experiment, two 100 W incandescent lamps were used to increase heat generation, and the highest composting process temperature was 41 °C. In the third experiment, 0.2 mm steel wall was used with two 100 W incandescent lamps and two fans, and the temperature of the composting process reached the thermophilic phase, namely 61°C on the 8th day.
Sampah merupakan sisa kegiatan manusia dan/atau proses alam yang berbentuk padat. Berdasarkan hasil pengamatan, diketahui bahwa di ketiga daerah rencana (Kabupaten Bogor, Kota Bogor, dan Kota Depok) sudah tidak memiliki TPA yang layak. Oleh karena itu pihak provinsi menyediakan TPA terpadu yang dapat melayani ketiga daerah tersebut. maka diperlukannya perencanaan jalur operasional menuju TPA terpadu tersebut. Perencanaan jalur dibuat menuju Stasiun Pengumpul Antara (SPA) terlebih dahulu sebelum menuju TPA. Perencanaan ini dilakukan dengan cara menghitung terlebih dahulu jumlah timbulan sampah sampai akhir tahun perencanaan kemudian menganalisa jalur existing yang ada dan membuat jalur yang baru. Dari hasil penelitian didapat timbulan sampah yang terlayani sampai akhir tahun perencanaan yaitu Kabupaten Bogor mencapai 12.845,30 m3/hari dengan persentase pelayanan 58 % untuk daerah domestik. Sedangkan timbulan sampah non domestik akan mencapai 3.537,51 m3/hari dengan persen pelayanan 100 %. Kota Bogor mencapai 6.824,86 m3/hari dengan persentase pelayanan 100 % untuk daerah domestik. Sedangkan timbulan sampah non domestik akan mencapai 219,47 m3/hari dengan persen pelayanan 100 %. Dan Kota Depok mencapai 11.179,43 m3/hari dengan persentase pelayanan 87 % untuk daerah domestik. Sedangkan timbulan sampah non domestik akan mencapai 395,32 m3/hari dengan persen pelayanan 100 %. Dari hasil pengamatan di lapangan, maka dibuat jalur terbaik menurut waktu dan jarak tempuh pengumpulan dan pengangkutan. Dalam perencanaan ini dilakukan juga analisa terhadap data dan perhitungan yang mengacu pada literatur dan dengan rumus-rumus yang ada dapat pula dihitung proyeksi kebutuhan armada sampai akhir tahun perencanaan.
