Abstract

Scads fish (Decapterus spp.) is a fish that is widely consumed by the community so that consumer demand in the market is high for Scads Fish. Based on the Statistics book from the KKP, the catch of Scadsfish has decreased in catches from 2014 to 2016, this is due to continuous catching. The purpose of this study was to estimate the sustainable potential and to determine the level of utilization of Scads Fish in Belawan Ocean Fishing Port, North Sumatra. The research data was obtained from the Belawan Ocean Fishery Port in February 2021. The method used in this study is a survey method, using an equation model, namely Schaefer. The data analysis is a simple linear regression analysis using SPSS version 20. The sustainable potential of Scads Fish (Decapterus spp.) in the last 5 years is 16,526 tons/year with a utilization rate of 67.98% which is included in the catch density category and the number of fish catches allowed is 13,221 tons/year.

Abstract

ABSTRACT. Sugar liquid can be used as supplementary feed for honeybees (Apis mellifera) because it may influence population development, egg production, and larvae, thereby enhancing colony productivity. This study aimed to determine the effect of adding sugar liquid on the development of Apis mellifera populations in standard hives. The research utilized 12 standard hives of Apis mellifera, each containing seven frames, with sugar liquid applied in four different treatments and three replicates. The treatments involved sugar liquid at a ratio of 3:1 (3 parts sugar and 1 part water), with levels of P0 = 0 kg, P1 = 0.33 kg/week, P2 = 0.66 kg/week, and P3 = 1 kg/week. The study employed a randomized block design (RBD), and data were analyzed using variance (ANOVA). Significant differences between treatments were further tested using Duncan's test. The results indicated that the addition of sugar liquid as supplementary feed did not significantly affect (P>0.05) the population, egg number, or larvae count of Apis mellifera. The study concludes that adding up to 1 kg of sugar liquid per week meets the basic nutritional needs of Apis mellifera but is not sufficiently effective in significantly increasing population, egg, or larval numbers.

Abstract

Penelitian ini bertujuan untuk mengetahui Maximum Sustainable Yield (MSY) terhadap hasil tangkapan udang Mantis (Harpiosquilla raphidea) di Perairan Pantai Timur Jambi, dilaksanakan pada bulan Mei 2023. Penelitian ini merupakan penelitian kuantitatif, menggunakan data sekunder yang diperoleh dari kantor Dinas Perikanan Tanjung Jabung Timur dan Tanjung Jabung Barat dari tahun 2017 sampai tahun 2022. Data yang diperoleh meliputi data hasil tangkapan udang Mantis dan upaya penangkapan (trip). Data yang diperoleh kemudian dianalisis menggunakan Microsoft Excel. Hasil penelitian ini menunjukkan hasil tangkapan dan upaya penangkapan yang dilakukan mengalami fluktuasi setiap tahunnya. Nilai hasil tangkapan per satuan upaya penangkapan (CPUE) yang diperoleh mengalami penurunan yang artinya apabila dibiarkan akan mengalami overfishing. Hasil CMSY dan EMSY sebesar 3.577,6315 ton/tahun dan 485.322,4971 trip/tahun. Jumlah tangkapan yang diperbolehkan (JTB) dari penelitian ini yaitu sebesar 2.862,1052 ton/tahun. Rata-rata tingkat pemanfaatan sumberdaya udang Mantis ini sebesar 96% dengan tingkat pengupayaan sebesar 94%. Berdasarkan hasil perhitungan tersebut disimpulkan bahwa potensi lestari udang Mantis di Perairan Pantai Timur Jambi ini belum mengalami overfishing. Namun, apabila terjadi penambahan upaya penangkapan (trip) maka potensi lestari udang Mantis tersebut dapat mengalami overfishing.

Abstract

This study aims to compare several extraction methods to obtain the active component of the qualitative Curcum rhizome. The data obtained were analyzed using descriptive analysis. Curcuma rhizome used comes from 4 types of plants Curcuma xanthorriza (temulawak), Curcuma domestica (turmeric), Curcuma mango (temu mangga) and Curcuma zedoaria (temu putih). The extraction method used consisted of maseration, reflux and soxhlet method. From the research result it was found that all three extraction methods can be used (maceration, soxhletasi and reflux) to extract the curcuma rhizomes. The result of phytochemical test of metabolite secondary detectable and very strong both of atsiri and non-essential oil group is using reflux method then new method of soxhletasi and then maceration method.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang mempengaruhi produksi dan biaya produksi, serta mengukur tingkat efisiensi teknis, alokatif, dan ekonomi pada usaha peternakan sapi di Kecamatan Renah Pemenang, Kabupaten Merangin. Selain itu penelitian juga menganalisis penyebab inefisiensi teknis dan ekonomi. Penelitian ini bersifat deskriptif dengan metode survei dan objeknya adalah usaha penggemukan sapi rakyat di wilayah tersebut. Data yang digunakan terdiri dari data primer dan sekunder. Hasil penelitian menunjukkan bahwa jumlah pakan hijauan, vitamin, obat-obatan, serta jenis ternak yang dipelihara berpengaruh positif dan signifikan terhadap produksi. Sementara itu harga bibit, pakan tambahan, dan obat-obatan berpengaruh signifikan terhadap biaya produksi. Rata-rata efisiensi teknis sebesar 0,90, efisiensi alokatif 0,88, dan efisiensi ekonomi 0,80. Hal ini menunjukkan bahwa usaha penggemukan sapi di wilayah penelitian telah efisien dalam ketiga aspek tersebut. Faktor yang menurunkan inefisiensi teknis adalah usia peternak dan intensitas penyuluhan, sedangkan inefisiensi ekonomi dipengaruhi oleh pengalaman beternak dan kepemilikan ternak. Temuan ini dapat menjadi acuan dalam meningkatkan kinerja usaha penggemukan sapi di daerah tersebut.

Abstract

The The waters of Carocok Tarusan Beach in Pesisir Selatan Regency have strong fisheries potential, with many coastal residents working as fishermen. This study aimed to inventory catches from seine net fishing gear and was conducted from July 20 to August 20, 2023, using a survey method with one 5 GT vessel and 10 landings. Data were collected through field observations and interviews. The results showed three species were caught, with tuna (Euthynnus affinis) as the main catch totaling 10,510 fish (1,251 kg; 77%), while anchovies (Stolephorus spp.) (128,100 fish; 173 kg; 11%) and peperek (Leiognathidae) (100,600 fish; 204 kg; 13%) were bycatch. The most frequent tuna sizes ranged from 282–305 mm and 338 359 mm, indicating tuna as the dominant catch in these waters.
