Abstract

Telah dilaksanakan kegiatan kepada masyarakat berupa pengembangan alat cetak briket di desa Jatireo kecamatan Gunungpati kodia Semarang. Latar belakang kegiatan ini adalah untuk mengatasi proses pembuatan briket pada saat dicetak, dimana hasil yang diperoleh belum padat sehingga lama nyala api belum sesuai yang diharapkan. Untuk mengatasi masalah tersebut telah dibuat alat pres yang digunakan untuk memberi beban briket sebelum dikeluarkan dari alat cetak. Hasil yang diperoleh menunjukkan adanya perbedaan ketebalan briket yang tidak dipres dengan yang dipres. Ketebalan briket tanpa menggunakan pres adalah 1 cm dan yang menggunakan alat pres 0,5 cm. Selain itu hasil uji pembakaran diperoleh laju pembakaran briket dari kulit kolang-kaling pada rentang 0.03-0.04 g/s. Hasil ini bersesuaian dengan briket dari jenis biomassa jenis lainnya seperti kayu, daun lain-lain dengan laju pembakarannya 0.03 g/s. Warna nyala api yang ditunjukkan ketika uji coba laboratorium adalah kuning kemerahan dan asapnya tidak menimbulkan gatal jika mengenai kulit.Kata kunci : briket, alat cetak, alat pres

Abstract

The increase of energy needs coupled with the decline in fossil fuel production, requires other sources of energy to meet those needs. One of the solution is using renewable energy. Bioethanol is one of the alternatives to the fossil fuel. This study was aimed at determining the exact mass of mango seeds in producing high grade bioethanol. Bioethanol was produced by fermentation of arum manis mango fruit seed using baker's yeast, Sacczharomyces cerevisiae.  The arum manis mango seeds were known to contain carbohydrate contents of 19.53%. The study was conducted by using different mass of mango seeds 25, 35 and 45 g resectively. The study showed that the samples of 25, 35 and 45 g produce ethanol with concentration of 4.78, 6.64 and 1.48%. These results indicated that the mass of 35 g mango seeds produced highest ethanol content.

Abstract

Development research has been carried out to measure high-level thinking skills of junior high school students, through the development of HOTS questions of Physics in Middle School. This is based on the lack of students' skills in answering questions that require analysis, evaluation, and creativity, so that in learning activities they cannot answer questions that require high-level thinking skills. Sampling was done randomly and obtained three classes, namely class VIII D, E, F. Then the data was collected using HOTS questions that have been tested by experts. The analysis used in this study was to test the material validity by experts, the validity of the items, the distinguishing power, the level of difficulty, the reliability of the test, and the t-test. The results of this study are a set of instruments about the HOTS Physics Middle School subject matter on objects that can be used to measure students' high-level thinking abilities.

Abstract

Bioethanol is an alternative energy of environmentally friendly as a substitute for petroleum. Sucrose, starch, and fibrous cellulose (lignocellulose) are the main ingredients for bioethanol production. The material is very easy and abundant to get from the waste of agricultural crops. One of these agricultural wastes in Indonesia that have not been used optimally is durian seeds. Durian seeds only become waste and are not commercially useful, even though they contain high carbohydrates, which is possible as a potential new source for bioethanol production. In this work, an experimental study was conducted on bioethanol synthesis from durian seeds through fermentation by Saccharomyces cerevisiae yeast in aerobic fermenter. The process for the production of starch-based bioethanol includes milling, hydrolysis, detoxification, fermentation, and distillation. At the stage of fermentation, variations in the duration of fermentation were applied for 1-11 days. Carbohydrates contained in durian seed flour are 11.541%, which is the largest content. The highest result of ethanol content is 14.72 % (v/v) in 9 day fermentation periods by using Saccharomyces cerevisiae in aerobic conditions. Distillation to enrich bioethanol was carried out by batch vacuum distillation at 68°C for ± 180 minutes and produced bioethanol with a purity of 95%.
