Persoalaan sampah rumah tangga, khususnya jenis sampah organic, masih menjadi issue yang mengemuka yang membutuhkan penyelesaian. Kebanyakan masyarakat masih menerapkan pola pengelolaan sampah konvensional yaitu menimbun sampah organic di suatu tempat/lokasi. Timbulan sampah ini berpotensi memunculkan masalah baru, seperti terjadi emisi gas metana (CH4), timbulnya bau yang tidak sedap, air lindi sampah berpotensi mencemari lingkungan. Karena itu kepada masyarakat perlu diberikan pembelajaran mengenai cara penanganan sampah organic untuk mengurangi jumlah sampah organic yang ditimbun di tempat pembuangan sampah. Salah satu caranya yaitu dengan memanfaatkan limbah organik segar, limbah buah dan/atau sayur, menjadi produk Eko-Ensim. Filtrat dari Eko-Ensim digunakan sebagai pupuk organic cair dan/atau pestisida nabati, sedangkan padatannya digunakan sebagai pupuk organic padat. Kegiatan ini dilaksanakan bermitra dengan Kelompok Pemanfaat Sampah “PaManSam” yang berlokasi di Desa Narmada Kecamatan Narmada Kabupaten Lombok Barat- NTB. Sebagai sasaran pembelajaran adalah petani milinial dan mahasiswa PKL di kelompok PaManSam. Kegiatan ini diawali dengan sosialisasi mengenai UU RI no 18 tahun 2008 dan Peraturan Daerah Provinsi Nusa Tenggara Barat Nomor 5 Tahun 2019 tentang Pengelolaan Sampah. Kegiatan kedua adalah Bimtek Pembuatan Eko-Ensim, diawali dengan persiapan bahan, pelaksanaan fermentasi Eko-Ensim, analisis karakteristik filtrat Eko-Ensim. Hasil kegiatan sebagai berikut, peserta kegiatan 1) memiliki pengetahuan tentang pengelolaan sampah menurut UU dan Peraturan Daerah yang berlaku; 2) menguasai teknik pembuatan Eko-Ensim; 3) Eko-Ensim yang dihasilkan ber-pH netral. Teknik pembuatan Eko- Ensim ini dapat diaplikasikan untuk membuatan produk lain dengan berbahan baku bahan organic segar

Every dry season the agricultural land in the Binong Region experiences drought so they have to collect water using a water pump that is driven by a diesel engine that is fueled by bio-solar. At this time the use of bio-diesel is limited so farmers often find it difficult to get it. The purpose of this research is to analyze PLTS as an alternative to bio-diesel fuel and to calculate the economic feasibility of PLTS. The method used is by conducting interviews and observing directly at the location and calculating using pre-existing equations. From this analysis, it can be concluded that this project is not investment-worthy. The results obtained from this research are that with a water pump power requirement of 2,400 watts, we need 10 pcs of 530wp monocrystalline solar panels, 4 pcs of 48v 100A lifepo4 batteries, SCC or MPPT with a capacity of 100A, inverter with a capacity of 5kw with a total initial investment of Rp. 121,088,187 and a total of Rp. 400,186,820 with a Cost of Energy of IDR 1,477.12/kWh and an NPV of IDR. 150,220,935.72 and net cash flow or DPP occurs in the 4th year.
