Modayag District, as the largest coffee-producing area and the largest land area in East Bolaang Mongondow Regency, has many obstacles to contribute to the achievement of coffee production. This research aims to discover the obstacles and strategies that can be done to develop coffee farming in Modayag District, East Bolaang Mongondow Regency. The analysis in this study is a qualitative descriptive analysis to determine the obstacles to the development of coffee farming and Process Hierarchy Analysis (AHP), which is used to determine strategies for developing coffee farming. The informants from this study were 12 key persons who were determined purposively to consist of related agencies, traders, and coffee farmers in the District of Modayag. The results showed that the obstacles in the development of coffee farming were the need for more information on cultivation techniques, the unavailability of post-harvest equipment, and the weak price protection and coffee quality assurance. With the AHP method, the results show that the policy aspect is the top priority, then the cultivation aspect, followed by the marketing aspect, the institutional aspect, and finally, the post-harvest processing aspect.</em></p> Dio Reski Saputro Ria Indriani Yuliana Bakari Copyright (c) 2023 JURNAL GALUNG TROPIKA http://creativecommons.org/licenses/by-sa/4.0 2023-08-12 2023-08-12 12 2 138 147 10.31850/jgt.v12i2.1077 Pertumbuhan Ikan Patin Siam (Pangasius hypophthalmus) Dipelihara dalam Sistem Bioflok dengan Frekuensi Pemberian Molase yang Berbeda http://jurnalpertanianumpar.com/index.php/jgt/article/view/1065 <p><em>Biofloc technology requires an additional carbon source (molasses) to balance the C/N ratio to support the bacteria's performance. The application of molasses should be done with sufficient time and concentration to guarantee the excellent condition of the floc. This study aims to determine the appropriate frequency of molasses application for the growth of siamese catfish (P. hypophthalmus) using Biofloc System Technology. The study used a completely randomized design of flour treatments and five replications. The frequency of molasses application was aimed to find the optimum results of applying it once a day (A), every two days (B), every three days (C), and every four days (D), each in the corresponding experimental units. The experiment was carried out in 35 days. The feed given was 5% of body weight, with a feeding frequency of twice daily. The results showed no difference in growth (weight) and feed efficiency for all treatments. However, it was found that the amount and nutrient content of the formed floc were more stable when molasses was given at a frequency every two days (treatment B) until the sixth week compared to other treatments. In conclusion, the frequency of giving molasses for flock growth twice a day can be applied for siamese catfish using the Biofloc system.</em></p> Muhammad Safir Ni Made Widyawati Achmad Rizal Novalina Serdiati Copyright (c) 2023 JURNAL GALUNG TROPIKA http://creativecommons.org/licenses/by-sa/4.0 2023-08-20 2023-08-20 12 2 148 158 10.31850/jgt.v12i2.1065 Analisis Pendapatan Usaha Pengolahan Ikan Asin pada Usaha Rumah Tangga di Bontang Kuala, Kalimantan Timur http://jurnalpertanianumpar.com/index.php/jgt/article/view/1107 <p><em>Indonesia is an archipelagic nation known as a maritime area with natural riches in fisheries, such as marine biota and marine tourism. Since 1952, the progress of Bontang Kuala City has been supported by various industrial centers that utilize fishery products. This study aims to study financial aspects, including income, expenses, efficiency, and profits in the salted fish processing business managed by residents who live around the coastal area of Bontang City. The instruments applied to analyze data are analysis of business efficiency, costs, revenues, and profits. The objectivity of the study relies on the method of direct interviews with informants. The study results show that the average fixed and variable monthly costs, average revenue, and average monthly profit are "very efficient." Even though the RCR in the salted fish processing business in Bontang Kuala is classified as "efficient", obstacles still lead to entrepreneurs' prosperity and the allocation of supporting equipment. The implications of the findings are discussed and explored in subsequent publications. The study's results also inspire and dedicate significant contributions to the direction of more adaptive stakeholder regulations in the future.</em></p> Erwin Kurniawan A.

This research was conducted in Mataran Village, Anggeraja District, Enrekang Regency, to analyze productivity risk management (ex-ante, post-Covid-19 shallot farming). The method in this research was quantitative descriptive with a sample size of 36 shallot farmers. The sampling technique used a simple random method (random sampling). The research results show that the respondent farmers' ex-ante risk management strategy is to carry out a planting pattern, namely shallots-shallots-shallots, with a monoculture system. The seeds used are sourced from other parties; generally, only one type of seed is planted for different lands. For interactive strategies used by respondent farmers, they are planting shallots at the end of the dry season before the rainy season, using organic and inorganic fertilizers, replanting if a plant dies, mixing pesticides to save costs and eradicate more pests and diseases. </em><em>Meanwhile, ex-post risk management means that if the shallot farming business fails, the action taken by the farmer is to look for additional work but continue to plant shallots in an area adjusted to the available capital. If there is a lack of capital, the respondent farmers borrow from fellow farmers or families, and some borrow from farmer kiosks or banks. Therefore, it is hoped that the role of agricultural extension workers will be more optimal in helping shallot farmers manage productivity risks and access capital.</em></p> N Nurhapsa S Suherman Copyright (c) 2023 JURNAL GALUNG TROPIKA http://creativecommons.org/licenses/by-sa/4.0 2023-08-22 2023-08-22 12 2 169 181 10.31850/jgt.v12i2.1089 Efektifitas Herba Ciplukan (Physalis angulata L.)

The materials used were 96 DOC with an average weight of 35-40 g, ciplukan herb from Luhak Nan Duo, the velogenic strain of Newcastle disease virus from Bvet Lampung, and the commercial vaccine ND Lasota. The study used a completely randomized design (CRD) with 8 treatments and 3 replications. The ciplukan herb was given for 3 days with concentrations: K(-) (without vaccine without ciplukan), K+ (vaccine only), E3 (ciplukan extract 0.35mg/10ml/head + vaccine), E2 (ciplukan extract 0.25mg/head 10ml/head + vaccine), E1 (0.15mg/10ml/head ciplukan extract + vaccine), S3 (17.5mg ciplukan powder/head + vaccine), S2 (12.5mg ciplukan powder/head + vaccine) and S1 (ciplukan powder 7.5mg/head + vaccine). The parameters observed in this study were antibody titer, morbidity, and mortality. The study showed that the administration of ciplukan herb positively affected low antibody titers through the efficiency of cellular defense mechanisms. This herb can also reduce chicken mortality and morbidity after challenge tests against the Newcastle disease virus.</em></p> N Nurhasanah Yulia Yellita S Sabrina A Ananda Copyright (c) 2023 JURNAL GALUNG TROPIKA http://creativecommons.org/licenses/by-sa/4.0 2023-09-20 2023-09-20 12 2 182 190 10.31850/jgt.v12i2.1074 Model Agroforestry yang Diterapkan Kelompok Tani Hutan (KTH) Berbasis Agribisnis di Desa Ulusaddang Kabupaten Pinrang http://jurnalpertanianumpar.com/index.php/jgt/article/view/1091 <p><em>This study aimed to identify the Agroforestry model applied by the Agribusiness-based KTH in Ulusaddang Village, Pinrang District, South Sulawesi.

The treatments in this research were cocoa beans from Soppeng Regency (South Sulawesi) and Polman Regency (West Sulawesi) with differences in fermentation time, namely 5 days and 7 days. The research results show that the raw material for cocoa beans used in making processed chocolate bars is influenced by the origin of the beans and the fermentation treatment. Visual test results showed that there was no difference in results for seeds from Soppeng and Polman. The processed product is brown in color and has a distinctive aroma because it comes from fermented cocoa beans. Testing for water content and fat content is greatly influenced by the fermentation process where a good stirring process during the fermentation process can increase the fat content and reduce the water content. Test results for metal contamination: Lead &lt;0.0134, Cadmium &lt;0.0013, Tin &lt;0.0776, Mercury and Arsenic &lt;0.0002.
