Abstract

This study aims to determine the optimum conditions of coconut milk to produce Virgin Coconut Oil (VCO) through combination of fermentation and enzymatic techniques. Technique is performed using a combination of the addition of yeast with a fixed concentration of 0.5 gram and pineapple extract (crude bromelain enzyme) with various concentration of 6 mL; 8 mL; 10 mL; 12 mL in 100 mL coconut cream, variations of pH 3 ; 4 ; 5 and the time of incubation for 24 hours at room temperature. Further analysis includes testing the quality of water content, free fatty acid content and iodine value obtained in the VCO. Results showed the treatment at pH 4; the addition of 0.5 grams of tempeh and 10 mL of pineapple extract produce optimum yield of 30.45 mL VCO. The test results of water content, free fatty acids and iodine value in a row is 0.27%; 0.144 mg KOH / g of oil; 7,12 mg iodine / 100 g oil. Virgin Coconut Oil (VCO) obtained good quality in accordance with SNI.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh salinitas terhadap daya tetas artemia dekapsulasi. Rancangan penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. Perlakuan A artemia dekapsulasi dengan salinitas 20 ppt Perlakuan B artemia dekapsulasi dengan salinitas 25 ppt, perlakuan C artemia dekapsulasi salinitas 30 ppt dan kontrol penetasan artemia non dekapsulasi salinitas 30 ppt. Hasil penelitian menunjukan bahwa terdapat perbedaan antar perlakuan. Daya tetas tertinggi terdapat pada perlakuan C yaitu Artemia dekapsulasi dengan salinitas 30 ppt sebesar 88,55%, daya tetas perlakuan B sebesar 68,51%, daya tetas perlakuan A sebesar 54,98%, dan kontrol menunjukkan daya tetas paling rendah yaitu sebesar 51,51%. Proses dekapsulasi dengan kadar Salinitas berbeda dalam proses penetasan siste artemia mempengaruhi daya tetas artemia. Artemia dekapsulasi dengan media penetasan bersalinitas 30 ppt mampu meningkatkan daya tetas sebesar 37,04% dari perlakuan kontrol.   This study aims to determine the effect of salinity on the hatching rate of decapsulated Artemia. The research design used a Completely Randomized Design (CRD) with 4 treatments and 3 replications. Treatment A of decapsulated artemia with a salinity of 20 ppt. Treatment B of decapsulated artemia with a salinity of 25 ppt, treatment C of decapsulated artemia with a salinity of 30 ppt and kontrol non-decapsulated artemia hatching with a salinity of 30 ppt. The research results showed that there were differences between treatments. The highest hatching rate was in treatment C, namely decapsulated Artemia with a salinity of 30 ppt of 88.55%, the hatching rate of treatment B was 68.51%, the hatching rate of treatment A was 54.98%, and the kontrol showed the lowest hatching rate of 51 .51%. The decapsulation process with different levels of salinity in the hatching process of the artemia system affects the hatching rate of artemia. Artemia decapsulation with hatching media with a salinity of 30 ppt was able to increase hatching rate by 37.04% from the kontrol treatment.

Abstract

This study aimed to determine the quantitative measurements of alcohol concentration, caffeine content, total dissolved solids, and total acid. This study used an experimental design with a non-factorial, Completely Randomized Design (CRD) that included three treatment levels, each replicated three times. The study consists of the following treatment levels: H5 represents the fermentation of cherry Arabica coffee for five days, H10 for ten days, and H15 for 15 days. The collected data underwent analysis of variance (ANOVA) using SPSS version 22. The Duncan's New Multiple Range Test (DNMRT) was used at a 5% significance level to determine the differences in the effects of each therapy. The study showed that the length of anaerobic fermentation of Arabica coffee cherries significantly affected the concentrations of alcohol, caffeine, total dissolved solids, and total acid (p<0.05). With longer fermentation, alcohol concentration, caffeine content, and total acid levels increase while the total dissolved solids content decreases. The most effective treatment in this study was noted on the 5th day of fermentation, showing an average alcohol content of 11.93%, caffeine content of 3.36%, total dissolved solids of 4.83oBrix, and total acid of 1.62%.

Abstract

ABSTRAK Jeruk Keprok Gayo (Citrus reticulata), komoditi pertanian ini pernah menjuarai kontes buah nasional pada tahun 1992 yang lalu. Tapi setelah itu, komoditi unggulan ini nyaris terlupakan, padahal jeruk keprok gayo masih tetap ada sampai sekarang. Melihat permasalahan di atas, identifikasi perlu dilakukan untuk mendapatkan informasi terhadap penyebaran sentra produksi jeruk keprok, karakteristik jeruk keprok, dan keanekaragaman sifat tanaman jeruk keprok lokal Aceh. Tujuan umum dalam penelitian ini adalah untuk mendapatkan daerah sebaran, karakter morfologi, dan kualitas buah jeruk keprok lokal Aceh. Metode pelaksanaan penelitian dilakukan dalam tiga tahap. Tahap pertama adalah eksplorasi tanaman, tahap kedua yaitu karakterisasi morfologi jeruk keprok lokal Aceh, dan tahap ketiga adalah analisis kemiripan tanaman jeruk keprok lokal Aceh berdasarkan karakter morfologi baik vegetatif maupun generatif. Hasil penelitian ditemukan penyebaran tanaman jeruk keprok di Kabupaten Bener Meriah yang paling banyak terdapat di Kecamatan Bandar tepat nya di desa Tanjung Pura. Penyebaran tanaman jeruk keprok di Kabupaten Aceh Tengah yang paling banyak terdapat di Kecamatan Kebanyakan tepat nya di desa Paya Tumpi yang menjadi salah satu sentral produksi jeruk keprok di Aceh. Tanaman jeruk keprok di Kabupaten Bener Meriah khususnya di Kecamatan Bukit dan Kecamatan Bandar mempunyai tinggi tanaman antara 10 sampai dengan 12  meter dengan tinggi rata-rata tanaman 10,7 m. Bentuk tajuk tanaman jeruk keprok di Provinsi Aceh di dua Kabupaten Bener Meriah dan Kabupaten Aceh Tengah  adalah elliptisoid . Helai daunya menunjukkan tidak adanya  variasi antara keseluruhan tanaman sample.  Panjang helaian daun berkisar antara 8,1 sampai 10,5 cm dengan lebar antara 3,1 sampai 4,2 cm. Kata kunci: Eksporasi, identifikasi, jeruk, keprok, aceh

Abstract

Bener Meriah Regency is one of the central coffee production areas in Aceh Province, especially in Taman Firdaus Village. Coffee bean processing generates waste in the form of coffee husks, which account for approximately 50-60% of the harvest. Therefore, there is a need for innovation to process coffee husks into a delicious coffee husk tea product with high economic value. Consequently, socialization and training activities are required to process coffee husks for target partners who are direct farmers. It is expected that these activities will: 1) increase the income of the community, especially partner groups, 2) become an alternative for partner groups to utilize coffee husks as a product with high economic value, and 3) cultivate an entrepreneurial spirit among partner groups for products produced through the utilization of Arabica coffee husks.

Abstract

The business world is an activity that includes the economy, including production, distribution, and other activities that aim to meet human needs and desires. Welding workshop services are one of the business sectors that continue to grow along with the increasing demand for security and aesthetics in buildings. The canopy functions as a protector from the heat of the sun and rain of a building. Therefore, it is important for welding workshop workers to have reliable skills and knowledge in making canopies. Community service activities aim to provide training and assistance on basic welding techniques on canopies that are useful for improving student competence. The method of activity carried out is a training technique with an allocation of theoretical and practical materials related to the basics of SMAW welding and welding on canopies which are attended by students of the Welding Engineering and Metal Fabrication Department, SMK Negeri 1 Bener Meriah. The results of the activity are as follows: can provide skills for vocational school students to enter the world of work related to the competence of operating SMAW welding machines correctly and can also connect plates on canopy construction using SMAW welding. The results of the material absorption of the student post-test showed a competence of 82%, this shows that students have gained welding skills on canopies and they hope that next year there will be a follow-up program.
