Efek pemberian pakan berlebih berupa limbah sayuran pakcoy terhadap daya cerna, tingkat penurunan limbah, dan kandungan protein pada lalat tentara hitam (Hermetia illucens (Linnaeus))

One of the recent organic waste management programs actively developed is organic waste bioconversion by using larvae of black soldier fly (Hermetia illucens (Linnaeus)). However, one major challenge in organic waste management in Indonesia is the limited space to manage the wastes at waste collection centers. This condition increases the number of wastes to be converted (consumed) by larvae of soldier fly. In this study, the condition was imitated in the laboratory where larvae were individually fed with a large number of wastes. Larvae were divided into 4 groups and were fed with 200, 300, 400, and 500 mg/larva/day of rotten vegetable waste (Pakcoy) and were replicated 3 times. Variables observed during the study were the growth rate, consumption capability, level of waste reduction (waste reduction index, WRI), consumption efficiency (efficiency of conversion of digested-feed, ECD), the weight of harvested biomass, and protein content of larvae, pupae, and adults. The results showed that there was no significant correlation between the weight of harvested biomass and the amount of substrate provided to larvae (one-way ANOVA, P > 0.05). The increasing amount of substrate reduced the efficiency of waste reduction and consumption (one-way ANOVA, P < 0.05). This study also showed that the possible upper limit of consumption capability of larvae was 400 mg/larva/day. On the other hand, the increasing amount of substrate increased the protein content of biomass of each developmental stage.

Peningkatan Pengetahuan Masyarakat Kotagede dalam Pengelolaan Sampah Organik

Sampah merupakan permasalahan klasik yang belum terpecahkan dengan baik. Kesadaran masyarakat terhadap pengelolaan sampah masih rendah, termasuk dalam pengelolaan sampah organik. Daerah perkotaan, umumnya menjadi penyumbang sampah terbesar. Studi ini dilakukan untuk mengetahui tingkat pengetahuan masyarakat Kotagede terhadap pengelolaan sampah organik. Sasaran studi adalah anggota Muhammadiyah di lingkup PCM Kotagede. Metode studi yang digunakan adalah metode survei. Pelaksanaan survei dilakukan sebelum dan setelah dilaksanakan penyuluhan tentang peningkatan nilai ekonomi sampah organik. Survei dilakukan terhadap 55 orang peserta penyuluhan Upaya Peningkatan Nilai Ekonomi Sampah Organik. Hasil survei sebelum dilaksanakannya penyuluhan, 100% peserta mengetahui bahwa sampah organik dapat diolah kembali. Dari proses pengolahan sampah tersebut terdapat 23 orang (42%) responden paham tentang pengolahan sampah. Setelah penyuluhan dilaksanakan, sebanyak 84% paham tentang proses pengolahan sampah, sedangkan 16% belum memahami. Dari hasil tersebut, semua peserta menghendaki dilakukannya pengelolaan sampah organik yaitu dengan praktek pembuatan pupuk organik.Increasing Knowledge of the Kotagede CommunityIn Organic Waste ManagementABSTRACTGarbage is a classic problem that has not been resolved properly. Public awareness of waste management is still low, including in organic waste management. Urban areas are generally the largest contributor to waste. This study was conducted to determine the level of knowledge of the Kotagede community on organic waste management. The target of the study is Muhammadiyah members within the PCM Kotagede. The study method used was a survey method. The survey was carried out before and after counseling on the increase in the economic value of organic waste. The survey was conducted on 55 participants of counseling on Efforts to Increase the Economic Value of Organic Waste. From the survey results before the implementation of counseling, 100% of the participants knew that organic waste could be recycled. From the waste processing process, 23 people (42%) of respondents understand about waste processing. After counseling was carried out, as many as 84% understood about the waste processing process, while 16% did not understand. From these results, all participants wanted organic waste management to be carried out by practicing organic fertilizer production. Keywords: Economic; compost; MPM Kotagede; Garbage

Campaign video for utilizing black soldier fly as organic decomposer in organic waste management

Waste management in Boyolali Regency, Central Java, is still experiencing problems. Around 71% of the total 167 tons of daily waste has not been managed properly, and 51.88% of which is organic waste. Since early 2020, Black Soldier Fly start-up has started organic waste management, sold larvae products, and conducted training and consultation on organic waste in various regions. However, due to the current Covid-19 pandemic, its product marketing has not been optimal. For this reason, a profile video was designed as a medium of campaign for environmental issues to make people aware of waste management, especially organic waste. The campaign video was developed using five stages of ADDIE research and development model. The produced video is expected to be a campaign medium for better environmental management.
