Abstract

Tumbuhan survival merupakan jenis tumbuhan liar yang dapat dikonsumsi atau dijadikan bahan makanan dan berkhasiat sebagai obat. Tumbuhan ini dapat dikonsumsi dalam keadaan darurat saat mendaki atau mejelajah didalam hutan sebagai pertolongan pertama. Penelitian ini bertujuan untuk mengetahui tingkat keanekaragaman tumbuhan survival dan jenis tumbuhan yang paling dominan di Taman Nasional Gunung Leuser Kecamatan Bahorok Kabupaten Langkat. metode pengambilan sampel yang digunakan yaitu metode belt transek (trasek sabuk) dan teknik purposive sampling dengan menjelajah sepanjang jalur pendakian. Penelitian ini dilakukan pada 2 lokasi dengan berbeda ketinggian: lokasi penelitian pertama 500 mdpl dan lokasi penelitian kedua 500-700 mdpl. Analisis data menggunakan indeks keanekaragaman Shannon-Wiener. Hasil penelitian yang didapatkan bahwa keanekaragaman jenis tumbuhan survival di Taman Nasional Gunung Leuser tergolong sedang melimpah dengan jumlah indeks keanekaragaman Shannon-Wiener H’= 1,1413. Jenis-jenis tumbuhan survival yang didapatkan terdiri dari 5 divisi, 7 kelas, 22 ordo, 22 famili, dan 27 spesies.

Abstract

The role of biotechnology is very rapid and broad in the aspect of fulfilling human needs, one of which is in the food industry. Biotechnology processes, both conventional and modern, cannot be separated from the role of microorganisms. Certain microorganisms are used in traditional food preparation through fermentation such as in the manufacture of yogurt, tape, cheese, soy sauce, yeast. Foods resulting from biotechnology that take advantage of the role of microorganisms and must pay attention to the critical point of halal. This needs to be considered so that each production process can be ensured to avoid contamination of non-halal materials. This product will later be used for Ms. PKK Bina Mufakat both for her own use and also as an entrepreneurial opportunity for the home industry. The problem of community service activities is that there is no group development in making biotechnology products, and there is no entrepreneurship development for PKK Bina Mufakat Gampong Bayeun. The method in service activities is a type of training method. The results of community service are the creation of a product that is useful and can be used as a home industry business opportunity.

Abstract

This study aimed to analyze the effect of the frequency of commercial feeding on the survival and growth of Asang fish larvae. This research was conducted from August to October 2021 at the Integrated Laboratory of the Faculty of Fisheries and Marine Sciences, Bung Hatta University, Padang, West Sumatra. This study used an experimental method with 3 treatments and 4 replications. The treatments in this study were Treatment A = Feed frequency 2 times a day; Treatment B = Feed frequency 3 times a day; and Treatment C = Feed frequency 4 times a day. Parameters observed in this study were survival of fish larvae (%), specific growth rate (%/day), absolute weight growth (mg), absolute length growth (mm), feed utilization efficiency and water quality. The data obtained from the research results were analyzed by one way ANOVA using SPSS 26.0 software. The results showed that the frequency of commercial feeding had a significant effect on the survival and absolute length growth of Asang fish larvae (P<0.05) and had no significant effect on the absolute weight growth of Asang fish larvae (P>0.05). Treatment C was the best frequency which resulted in the highest absolute survival (35.78±2.00), growth in absolute weight of ang fish larvae (15.03±1.64 mg) and length (5.03±0.16 mm). feeding according to gastric emptying of Asang fish larvae.
