Tofu pulp is a by-product of tofu processing which still contains high enough protein because in the process of knowing not all proteins can be extracted. The focus of the problem on the local community starts from observations in the field where some people have a home industry that knows its pulp not yet maximally utilized only limited to animal feed additives. Based on this problem it is necessary to empower rural communities, especially household mother by providing counseling and traini ng on the use of vilages such as tofu industry waste to be processed into useful products with high economic value.Tofu dregs become crackers and abon in addition to nutritious family food (food diversification) as well as additional household income.

The research on the utilization of waste cabbage (Brassica oleracea) as a preservative tilapia (Oreochromis sp) with RAL factorial method with 2 replications.The first factor is the concentration of NaCl with a password (N) which consists of 4 levels, namely: N1 = 1%, N2 = 2%, N3 = 3% , N4 = 4%. Factor II is a password storage time (P) which consists of 4 levels, namely: P1 = 1 days, P2 =3 days, P3 = 5 days, P4 = 7 days.The parameters observed from the data analysis showed that NaCl concentration and storage time significantly affected the protein content, moisture content, organoleptic aroma, texture organoleptic tests,and organoleptic color not significant.

Polikarbonat merupakan bahan sintesis hasil reaksi antara bisphenol-A (BPA) dengan phosgene (carbonyl dichloride/ COCl2). Bisphenol-A merupakan zat berbahaya yang dapat bermigrasi dari polikarbonat ke air. Penelitian ini bertujuan untuk mengambil sikap preventif atau pencegahan yaitu dengan menganalisis kadar bisphenol-A (BPA), yang dapat bermigrasi dari kemasan jenis polikarbonat ke dalam air, dengan menggunakan metode analisis spektrofotometri ultraviolet (UV). Berdasarkan penelitian yang telah dilakukan, pada sampel botol polikarbonat yang disimpan pada suhu ruangan 23oC tidak mengandung bisphenol-A. Sedangkan pada sampel yang disimpan pada suhu paparan sinar matahari berkisar 30oC mengandung bisphenol-A BPC 2 A, BPC 2 B, dan BPC 2 C masing-masing 0,0257 ppm, 0,0211 ppm, dan 0,0234 ppm. Sampel yang ditambahkan air panas pada suhu 100oC mengandung bisphenol-A BPC 3 A, BPC 3 B, BPC 3 C, masing-masing 0,0468 ppm, 0,0495 ppm, dan 0,0445 ppm. Dapat disimpulkan bahwa suhu memberikan pengaruh terhadap migrasi bisphenol-A pada kemasan botol polikarbonat ke air di dalamnya. Hasil kadar bisphenol-A pada sampel botol polikarbonat masih memenuhi syarat batas maksimal 0,6 ppm menurut Peraturan Kepala Badan POM. No HK.03.1.23.07.11.6664. Kata kunci: bisphenol-A, polikarbonat, spektrofotometri UV. Polycarbonate is a synthetic material resulting from a reaction between bisphenol-A (BPA) and phosgene (carbonyl dichloride/ COCl2). Bisphenol-A is a dangerous substance that can migrate from the polycarbonate into water. This study aimed to take a preventive action by analyzing the content of bisphenol-A (BPA), which could migrate from the polycarbonate packaging into the water, using ultraviolet (UV) spectrophotometry. Based on the research conducted, for the sample of polycarbonate bottle stored at room temperature of 23?C, no bisphenol-A contained in the water. Meanwhile, for the samples stored under the sun exposure at temperature of about 30?C, the water contained bisphenol-A BPC 2 A, BPC 2 B, BPC 2 C of 0.0257 ppm, 0.0211 ppm and 0.0234 ppm respectively. Furthermore, for the samples added with hot water at a temperature of 100?C, the water consisted of bisphenol-A BPC 3 A, BPC 3 B, BPC 3 C of 0.0468 ppm, 0.0495 ppm, and 0.0445 ppm respectively. It could be concluded that the temperature influenced the migration of bisphenol-A from the polycarbonate bottles into the water stored in the bottles. The bisphenol-A levels in the sample of polycarbonate bottles still met the maximum limit of 0.6 ppm according to the Regulation Head of POM. No HK.03.1.23.07.11.6664. Key words: bisphenol-A, polycarbonate, UV spectrophotometry.

Pengolahan pangan semakin berkembang seiring dengan perkembangan pengetahuan dan perkembangan teknologi. Berbagai inovasi dilakukan oleh beberapa industri pengolahan makanan dalam menciptakan produk makanan baru yang dapat diterima masyarakat. Seiring dengan beragamnya jenis makanan olahan dari buah pisang, maka meningkat pula jumlah limbah yang dihasilkan dari para pengusaha olahan pisang tersebut. Tujuan dari kegiatan ini adalah memberikan pengetahuan dan pemahaman kepada mitra dalam pengolahan limbah kulit pisang menjadi selai kulit pisang. Sasaran program pengabdian ini adalah Aisyiah Ranting Gedung Johor Kecamatan Medan Johor yang berjumlah 10 orang. Mitra yang ikut berpartisipasi adalah anggota Aisyiah yang tergolong dalam usia produktif dan berprofesi sebagai ibu rumah tangga. Metode dalam kegiatan pengabdian ini adalah: (1) sosialisasi atau penyuluhan, yaitu memberikan pemahaman kepada mitra sasaran akan kesadaran kelestarian lingkungan, (2) pelatihan, yaitu memberikan pengetahuan kepada mitra sasaran bagaimana mengolah limbah kulit pisang menjadi selai kulit pisang. Hasil yang diperoleh dari kegiatan pengabdian ini adalah antusias mitra sasaran dalam setiap proses, umpan balik dari mitra sasaran yang dinilai positif dan memberikan manfaat kepada mitra sasaran baik dalam bidang sosial yaitu memberikan rasa percaya mitra untuk berwirausaha maupun bidang ekonomi yaitu sebagai penambah penghasilan keluarga.

Palm briquette briquette production as one of the fuel substitutes that began to thin and as a source of renewable alternative energy is done with the addition of cassava starch. This research used Factorial Randomized Complete Design (RAL) with two replications. Factor I is the addition of cassava husk starch with a password (P) consisting of 4 levels, namely: P1 = 5%, P2 = 10%, P3 = 15%, P4 = 20%. Factor II is the drying temperature with the code (S) consisting of 4 levels, namely: S1 = 100 0 C, S2 = 110 0 C, S3 = 120 0 C, S4 = 130 0 C. Parameters observed included heating value, moisture content, ash content. Statistical analysis result on each parameter show: The addition of Cassava Starch has a very significant different effect (P <0.01) on the calorific value. The addition of Cassava Starch gave a very significant different effect (P <0.01) on Briket Water Content. The addition of Cassava Starch gave a very significant different effect (P <0.01) on Ash Content in Briquette.
