“…When the water content ratio to biodegradable organic matter is too high, the heat generated from the biodegradation process is insufficient to evaporate the water. On the other hand, the waste degradation process (high water content) will produce more leachate and decrease caloric value [23][24][25].…”

Sampah sayuran merupakan jenis sampah organik biodegradable yang dapat ditemukan di setiap lokasi di Indonesia. Selain itu, timbunan sampah sayuran juga mendominasi sampah makanan. Pemanfaatan lebih lanjut sampah sayuran salah satunya dapat menggunakan pemulihan energi. Pemulihan energi sampah sayuran dapat dilakukan dengan biodrying yang tergantung dengan waktu dan bioaktivator. Tujuan dari studi ini adalah untuk mengetahui pengaruh waktu dan pemberian aktivator pada proses biodrying sampah sayuran. Penelitian ini menggunakan sampah seberat 0,5 kg dengan pemberian laju alir udara 15 liter/menit, suhu pada proses berada pada rentang 28,4-34,1°C. Biodaktivator yang digunakan dalam penelitian ini adalah ragi roti, tempe, dan tape. Penurunan massa maksimum terjadi pada proses biodrying dengan penambahan bioaktivator. Hasil uji pengaruh pada multivariate menunjukkan adanya pengaruh waktu dan bioaktivator pada perubahan nilai kadar air dan nilai kalor. Akan tetapi, interaksi antara waktu dan bioaktivator hanya berpengaruh pada kadar air. Hal ini karena proses degradasi terjadi memanfaatkan mikroorganisma yang tersimpan di dalam cairan bioaktivator dan air dalam sampah sayuran. Penelitian lebih lanjut diperlukan untuk mengetaui lebih jelas pengaruh variabel lain dalam proses biodrying terutama pada waktu detensi yang tepat dan bioaktivator yang mempercepat laju degradasi.Vegetable waste is a type of biodegradable organic waste found in every location in Indonesia. In addition, vegetable waste also dominates food waste. One of the ways to use vegetable waste is to use energy recovery. Energy recovery of vegetable waste can be done by time-dependent biodrying and bioactivator. This study aimed to determine the effect of time and activator application on the vegetable waste biodrying process. In this study, 0.5 kg of waste is used with an airflow rate of 15 liters/minute, the temperature in the process is in the range of 28.4-34.1°C. The bioactivators used in this study were baker's yeast, tempeh, and tape. The maximum decrease in mass occurs in the biodrying process with the addition of a bioactivator. The multivariate effect test results showed an effect of time and bioactivator on changes in water content and caloric value. However, the interaction between time and bioactivator only affects the water content. This is because the degradation process occurs utilizing microorganisms stored in the bioactivator liquid and water in vegetable waste. Further research is needed to know the effect of other variables in the biodrying process, especially the right detention time and bioactivators that accelerate the rate of degradation.

“…Angka ini mewakili hanya sekitar 0,22% dari total sampah yang dihasilkan di Kabupaten Buleleng pada Tabel 1, yang mungkin tampak kecil. Penting untuk diperhatikan bahwa ini merupakan usaha yang dilakukan pada skala rumah tangga, yang secara alami memiliki kapasitas yang lebih terbatas dibandingkan dengan fasilitas pengelolaan sampah skala lebih besar [21]. Ketika fokus khusus pada sampah sisa makanan, yang totalnya mencapai 5.731,35 ton setiap tahun, kontribusi dari fasilitas komposting menjadi lebih signifikan, dengan mengurangi sebanyak 5,41% dari total sampah sisa makanan.…”

This study focuses on the analysis of domestic waste management in Buleleng Regency based on data from the National Waste Management Information System (SIPSN) managed by the Ministry of Environment and Forestry. The background of this study is grounded on the necessity to comprehend the basic characteristics of waste in Buleleng and its challenges and solutions. Employing descriptive analysis and literature study methods, this research successfully maps the composition, quantity, and waste management methods in the regency. Results indicate that the composition of domestic waste is dominated by specific types and, compared to other urban areas in Indonesia, there are distinct characteristics in waste management in Buleleng. A brief conclusion from this study emphasizes the need for a more integrated and sustainable waste management strategy in Buleleng Regency.

“…Proximate analysis of solid fuels is used to determine the characteristics and quality concerning the use of the coal, namely to determine the relative amount of moisture content, volatile matter (VM), ash, and tethered carbon (FC) contained [18][19][20]. This proximate analysis is the most basic test in determining the quality of solid fuels [20][21][22]. Based on the data in Table 2, the moisture content is 28.32%; this the amount of water content contained in the sludge oil waste.…”

With the ever-increasing need for waste management solutions, PT. X Plaju is one of the entities that contribute to B3 waste production, a waste type characterized by its explosive, flammable, reactive, corrosive, and toxic properties. This research centers on the evaluation and management of B3 waste sludge, particularly at PT. X Plaju. The institution implements two licensed B3 waste control programs: the Sludge Oil Recovery (SOR) and used lubricant utilization programs. The SOR program, which focuses on recovering components from oil deposits or sludge, operates under the recovery principle. This study showcases the importance of the oil component in the oil sludge, emphasizing that it must constitute more than 20% of the total volume to be deemed suitable for refinery production. Our findings highlighted a water content of 28.32% within the waste oil sludge. Additionally, the ultimate analysis showcased carbon, hydrogen, and nitrogen compositions of 85.99%, 13.42%, and 0.21%, respectively, while the density was measured at 0.85 gr/cc. This research offers insights into the waste management practices of PT. X Plaju, emphasizing the potential of the SOR program in managing B3 waste effectively.
