Abstract

Kimpul (Xanthosoma sagittifolium) memiliki kandungan pati alami yang tinggi sehingga berpotensi sebagai bahan baku pembuatan pati modifikasi. Pati alami memiliki banyak kelemahan sehingga perlu dilakukan proses modifikasi untuk mengatasi kekurangan dan meningkatkan fungsionalnya. Pada penelitian ini dilakukan modifikasi pati kimpul dengan metode hidrolisis enzimatis menggunakan kecambah kacang hijau sebagai sumber enzim α-amilase. Tujuan penelitian adalah menentukan kondisi terbaik konsentrasi kecambah kacang hijau dan waktu inkubasi berdasarkan analisis parameter uji meliputi yield, daya serap air, dan daya kembang pati kimpul termodifikasi. Proses modifikasi enzimatik dilakukan dengan menginkubasi pati kimpul yang dicampur dengan kecambah kacang hijau pada berbagai konsentrasi (20, 25, 30, dan 35% dari pati yang akan dimodifikasi) pada suhu 30°C selama 1, 2, dan 3 hari. Hasil penelitian menunjukkan bahwa kondisi terbaik diperoleh pada konsentrasi kecambah 35% dan lama inkubasi 2 hari dengan yield 99,2006%, daya serap air 3,58 g/g, dan daya kembang 35,14%.

Abstract

Canna starch has the potential to be a raw material for biodegradable plastic because it has a total starch content of 93.30%, amylose content of 42.40% and amylopectin 50.90%. The research aims to study the effect of the ratio of canna starch and casein rejected milk with sorbitol modification on the characteristics of biodegradable plastic. The variables of this research were the ratio of canna starch and casein from rejected milk (4:0; 3:1; 2:2) and stirring for 30 minutes at 75°C and the addition of sorbitol (2%, 3%, 4% , 5%). The process of making biodegradable plastic is carried out by pouring a biodegradable plastic solution according to variables into a mold, then drying it using an oven at 70°C for 6 hours and the mold is taken out to dry at room temperature for 24 hours. The plastic formed is tested for tensile strength, elongation, biodegradation, morphology. The results of this research show that the higher the canna starch added and the lower the casein added, the more water resistance, tensile strength, elongation increases, and biodegradation increases. The smaller the ratio of canna starch and milk casein (the greater the amount of milk casein), the higher the water resistance, tensile strength, elongation and biodegradability of the resulting bioplastic. The best combination ratio of starch and casein was obtained at a ratio of 4:0 which provided the highest water resistance of 81.82%, the highest tensile strength of 5.48 MPa, the highest elongation of 26.67, and the highest biodegradation of 0.08. The higher the amount of sorbitol added increases the value of elongation, biodegradation. The best addition of sorbitol was obtained at a concentration of 5% which provided the highest elongation of 8.57, biodegradation of 0.11, while the best tensile strength was obtained at a concentration of 1% of 3.40 MPa.

Abstract

The increase in population and household consumption can lead to an increase in the volume of household waste. The increase in the volume of household waste will become a serious problem if no processing efforts are made. If household-scale waste processing is not carried out, it can result in the accumulation of the volume of organic waste in the Integrated Waste Management Site (TPST). One of the efforts that can be made to process waste at the household scale is by decomposing it using BSF larvae (maggot). Household waste generally consists of vegetable scraps and fruit peels. Vegetable and fruit waste is classified as organic waste which contains many nutrients that are utilized by BSF larvae as a food source in their breeding. The ability of BSF larvae to eat organic waste makes them widely used as one of the biodecomposter agents. This study aims to determine the effect of waste type and variation in the number of maggot on feed conversion efficiency, waste reduction index and characteristics of maggot produced. This study was conducted with a complete randomized design method with two independent variables and two repetitions. The physical characteristics of maggot which include, digested feed conversion efficiency (ECD), waste reduction index (WRI), and protein content in dried maggot. The type of garbage has no significant effect on the value of feed conversion efficiency (ECD), has a significant effect on the value of the waste reduction index (WRI) and has a very significant effect on protein content. The variation in the number of maggot has a very significant effect on the value of feed conversion efficiency (ECD) and waste reduction index (WRI) and has a significant effect on protein content.

Abstract

SMA Negeri 1 Limbangan Kendal terletak di Jalan Limbangan No 1, Krajan, Kecamatan Limbangan Kabupaten Kendal Jawa Tengah memiliki visi mewujudkan manusia yang berkarakter, berilmu, terampil, berdaya saing global, dan berwawasan lingkungan hidup. Salah satu sarana untuk mewujudkan sifat dan sikap kreatif para siswa SMA Negeri 1 Limbangan Kendal adalah dengan mengadakan pelatihan pembuatan produk-produk kimia terapan. Kehadiran tim pengabdian masyarakat Prodi D3 Teknik Kimia Polteka Mangunwijaya bertujuan untuk membuka wawasan para siswa tentang jenis, prinsip, dan cara pembuatan produk kimia terapan. Salah satu produk kimia terapan yang mudah dibuat adalah sampo rambut. Metode yang dilakukan dalam kegiatan pelatihan ini dibagi menjadi 3 sesi utama, antara lain: penjelasan klasikal, praktik pembuatan produk, dan sesi tanya jawab. Hasil dari kegiatan ini adalah produk sampo dan antusiasme para siswa SMA Negeri 1 Limbangan Kendal dalam memahami dan mempraktikkan proses pembuatan sampo rambut. Pengetahuan mengenai alat dan bahan, prinsip, dan cara pembuatan sampo rambut diharapkan dapat meningkatkan kreativitas para siswa dalam mengembangkan produk-produk kimia terapan lainnya.

Abstract

Desa Mluro Kecamatan Boja Kabupaten Kendal, Provinsi Jawa Tengah merupakan sentra industri pati aren, terdapat 27 pengrajin pati aren dengan kebutuhan bahan baku batang aren untuk produksi  mencapai  150 ton per hari. Limbah ampas pati aren yang dihasilkan dari proses produksi tepung aren mencapai 100 ton/ hari. Hasil tinjauan lapangan dan pembicaraan dengan dua kelompok pengrajin ditemukan permasalahan yang sedang dihadapi yaitu masalah limbah ampas aren yang belum dimanfaatkan, sehingga perlu diajarkan teknologi pembuatan briket ampas aren. Pelaksanaan program Iptek bagi Masyarakat (IbM) di Kabupaten Kendal telah dapat di selesaikan dengan baik. Hasil pelaksanaan program tampak adanya perubahan pada kelompok masyarakat sebagai berikut : terserapnya teknologi pembuatan briket oleh pengajin pati aren, kemauan untuk membuat briket sebagai sumber penghasilan, memberi tambahan lapangan kerja bagi warga sekitar, menjalin kerjasama dengan pengusaha yang bersedia membeli produk briket, mengatasi pencemaran sungai. Dari hasil penelitian menunjukkan bahwa briket biomassa berkarbonasi dari limbah ampas pati aren, mampu menghasilkan nilai kalor sebesar  5234,5 kkal/kg (lebih tinggi dari SNI nilai kalor briket biomassa: 5000 kkal/kg ).Kata kunci : briket, karbonisasi, limbah ampas aren. Abstract. Kendal Regency, Central Java Province is the center of the palm starch industry, there are 27 palm starch craftsmen with the raw material needs of palm stems for production reaching 150 tons per day. The waste of palm starch dregs produced from the production process of palm flour reaches 100 tons/day. From the results of field reviews and discussions with the two groups of craftsmen, it was found that the problem that is being faced by the palm starch craftsman groups is the problem of palm pulp waste that has not been utilized, so it is necessary to teach the technology of making palm dregs briquettes. The implementation of the IbM program in Kendal Regency has been completed. From the results of the program implementation, it appears that there are changes as follows: the absorption of technology for making briquettes by palm starch craftsmen, the willingness to make briquettes as a source of income, providing employment for local residents, establishing cooperation with entrepreneurs who are willing to buy briquette products, overcoming river pollution. Carbonated biomass briquettes from palm starch waste are able to produce a calorific value of 5234.5 kcal/kg (higher than the SNI calorific value of biomass briquettes: 5000 kcal/kg).Keywords: briquettes, carbonization, palm pulp waste.
