Kegiatan IBM ini bertujuan mengatasi permasalahan masyarakat, dimana selama ini masyarakat desa rambungan I dan II yang selama ini kegiatannya kebanyakan bekerja sebagai buruh bangunan untuk menghidupi keluarganya, sehigga jika pekerjaan tidak ada maka mereka akan sangat kesulitan menghidupi keluaraganya, sehingga timbul ide untuk meningkatkan pendapata masayrakat melalui kegiatan budidaya belut dengan memadapatkan sampah organic untuk media hidup makanan tambahan agar belut dapat tumbuh dan berkembang dengan baik dan panen dengan hasil yang memuaskan. Untuk itu dibuat serangkaian kegiatan untuk meningkatkan pendapatan masyarakat melalui kegiatan pengabdian Iptek Bagi Masyarakat, hasil kegiatan ini adalah masyarakat memelihara belut dan cacing yang berguna untuk makanan belut dan umpan memancing. Namun secara keseluruhan kegiatan ini harus dilanjutkan lagi untuk mencapai tujuan awalnya. Kata kunci : Belut Organik, Masyarakat miskin.

Pada penelitian ini dilaporkan perubahan suhu transisi gelas produk pencangkokan anhidrida maleat pada karet alam siklis. Pencangkokan anhidrida maleat pada karet alam siklis dilakukan dalam fase leleh dengan penambahan komonomer divinil benzen di dalam pencampur internal suhu 185oC dan kecepatan rotor 85 rpm. Konsentrasi anhidrida maleat yang digunakan dalam proses pencangkokan adalah 16 phr, tanpa penambahan dan dengan penambahan komonomer divinil benzen dengan variasi: 0,5, 1 dan 2 mol rasio. Produk pencangkokan dikarakterisasi dengan Differential Scanning Calorimetry untuk mempelajari perubahan suhu transisi gelasnya. Berdasarkan analisis dan pengolahan data menggunakan software thermal analysis diperoleh bahwa semakin banyak penambahan komonomer divinil benzene maka suhu transisi gelasnya semakin tinggi, yaitu: 69,46oC, 69,51oC, 70,08oC dan 70,56oC.

Asam lemak sawit distilat (ALSD) merupakan hasil samping dari pabrik minyak goreng kelapa sawit dan mengandung squalen sekitar 1%. Squalen dapat digunakan sebagai bahan dasar dalam industri kosmetika dan obat-obatan. Pada penelitian ini squalen diperoleh dari saponifikasi ALSD yang dilanjutkan dengan ekstraksi dan pencucian sehingga diperoleh cairan berwarna kuning yang kemudian dianalisis menggunakan gas chromatography (GC) dan Fourier Transform Infra Red (FTIR). Pemurnian cairan ini menggunakan kromatografi kolom dengan fase gerak heksan dan fase diam silika gel tipe 60. Hasil penelitian menunjukkan bahwa karakteristik ALSD adalah kadar air 0,30 %, asam lemak bebas (ALB) 90,56 %, bahan tak tersabunkan 9,03 %, bilangan penyabunan 223,23 mg KOH/g, bilangan peroksida 25,86 mek/Kg. Sementara komposisi asam lemak di dalam ALSD adalah asam laurat (C:12) 0,19 %, asam miristat (C:14) 1,03 %, asam palmitat (C:16) 48,59%, asam stearat (C:18) 3,71 %, asam oleat (C:18:1) 37,74%, asam linoleat (C:18:2) 7,97 %, dan asam linolenat (C:18:3) 0,21 %. Sementara itu kandungan squalen di dalam bahan tak tersabunkan adalah 139.000 ppm. Squalen yang diperoleh masih tidak murni terbukti dengan hasil analisis FTIR munculnya puncak pada bilangan gelombang 1700 cm-1 yang menunjukkan gugus C=O karbonil. Pemurnian dengan kromatografi kolom dapat memurnikan squalen hingga konsentrasi 239.000 ppm.

The development of biodiesel which is currently increasing has helped increase glycerol as a by-product. The glycerol can be obtained from a transesterification reaction in either vegetable or animal oils or fats and even used cooking oil. Glycerol buildup without further processing can reduce the selling price of glycerol. One solution to overcome this is to convert it to surfactants such as glycerol esters which are widely used in various industries such as chemistry, food, cosmetics, medicine and textiles. This study aims to utilize used cooking oil as a source of glycerol used in the synthesis of glycerol ester surfactants, as well as to compare the quality of glycerol ester surfactants produced by the use of commercial glycerol. The process begins by isolating glycerol from used cooking oil and then purifying it to improve its quality. Then glycerol ester was synthesized by using stearic acid, palmitic acid and oleic acid at reaction times of 120, 150 and 180 minutes. The highest yield of ester glycerol produced was at the reaction time of 180 minutes for each use of fatty acids. The test results showed that the glycerol ester produced was able to reduce the surface tension of the water. The value of hydrophylic-lipophylic balance (HLB) is not much different in the range of 5, and the use of various fatty acids and different sources of glycerol results in % of the stability of different emulsions.
