Thevia Nur Afriani Sutiana Putri — 2026-07-29

The complex nutritional content of goat milk is classified as a food product that is susceptible to spoilage. This is due to the growth of microorganisms, particularly pathogenic bacteria. Therefore, processing fresh milk into powdered milk is one way to preserve the nutrients in milk. The addition of ingredients such as maltodextrin is necessary to serve as a carrier agent in the drying process. The objective of this study is to determine the effect of maltodextrin addition on the physical and chemical characteristics of goat milk powder using a drum dryer method. In this study, a Randomized Block Design (RBD) was used with four different treatments based on variations in maltodextrin concentration, namely 5%, 10%, 15%, and 20%, each repeated twice to ensure the validity of the results. The data obtained were analyzed to assess the effect of the treatments on various quality parameters, such as moisture content, ash content, protein content, carbohydrate content, solubility, yield, fat content, and hygroscopic properties. The results of the analysis of goat milk powder with maltodextrin addition using the drum dryer method in treatment P4 were moisture content (2.40%), ash content (3.41%), protein (10.16), fat (29.51%), carbohydrate (56.92), hygroscopicity (30.31%), solubility (90.02), and yield (98.93). The addition of maltodextrin to the physical and chemical characteristics of goat milk powder did not significantly affect the hygroscopicity but significantly affected the moisture content, ash content, protein, fat, carbohydrates, solubility, and yield.

Kinerja usaha Kuritos berbasis balanced scorecard di Kabupaten Kaur Provinsi Bengkulu

Salsa Bila — 2026-07-29

Kaur Regency has significant potential for octopus resources, with production reaching 276,031 kg per year, encouraging the development of processing-based enterprises, including IKM Putra Daerah, which produces octopus crackers under the brand “Kuritos.” However, high availability of raw materials does not necessarily translate into optimal business performance. Theoretically, the Balanced Scorecard emphasizes that business performance should be achieved by balancing financial and non-financial aspects. In reality, the Kuritos business demonstrates relatively good financial performance but still faces limitations in production capacity and employee productivity, resulting in suboptimal overall performance. This gap between the ideal condition and the actual situation forms the basis of this study. This research aims to analyze Kuritos' business performance across financial and non-financial dimensions using the Balanced Scorecard approach. The study employs a case study design with a qualitative descriptive approach supported by quantitative data. The results indicate that financial performance is considered good, with an R/C ratio of 1.20 and a break-even point already achieved; however, business profits remain relatively low relative to the regional minimum wage. In terms of non-financial aspects, customer and employee satisfaction are relatively high, but production volume and employee productivity have not yet reached the expected targets. Overall, business performance is categorized as moderate, with a score of 0.6, indicating a need to strengthen production capacity and marketing strategies to sustainably improve performance.

Studi komparatif media penyimpanan silo tong dan silo plastik terhadap kualitas organoleptik dan palatabilitas silase

Sari Suryanah — 2026-07-29

This study aimed to evaluate and compare the effects of drum silo and plastic silo storage media on the organoleptic quality and palatability of silage. The method used was an experiment with two treatments and six replications, namely silage stored in drum silos (P1) and silage stored in plastic silos (P2). The organoleptic parameters observed included aroma, taste, color, and texture, while the palatability parameters included feeding duration and silage intake. Data were analyzed using the Shapiro-Wilk test for normality, followed by the Mann-Whitney test because the data were not normally distributed. The results showed that there were no significant differences (p>0.05) between treatments P1 and P2 for all organoleptic and palatability parameters. The average scores for aroma, taste, color, and texture indicated that both treatments produced high-quality silage that was well-accepted by both panelists and livestock. This indicates that both types of storage containers, drum silos and plastic silos, were able to maintain optimal fermentation conditions during ensiling without reducing the organoleptic quality and palatability of silage.

Pengujian racun perut ekstrak aseton tanaman putri malu (Mimosa pudica L.) untuk mengendalikan hama Spodoptera frugiperda

Dewi Wulan Sari — 2026-07-29

Maize (Zea mays L.) is one of the major agricultural commodities that contributes significantly to national food security and economic development. However, maize production is constrained by infestations of the fall armyworm (Spodoptera frugiperda), a destructive pest capable of causing substantial yield losses. Botanical pesticides have emerged as an environmentally friendly alternative for managing this pest. This study aimed to evaluate the ingestion toxicity of acetone extract of Mimosa pudica L. against S. frugiperda. The experiment was conducted at the Plant Pest and Disease Laboratory, Faculty of Agriculture, Universitas Islam Sumatera Utara, from April 24 to October 15, 2022. A completely randomized design (CRD) with a single factor was applied, consisting of five treatments: control, 0.125%, 0.25%, 0.375%, and 0.5% acetone extract of M. pudica, each with five replications. Fresh M. pudica plants were extracted using acetone solvent, and the resulting extract was applied as an ingestion treatment to S. frugiperda larvae. The observed parameters included larval mortality, median lethal time (LT??), and median lethal concentration (LC??). The highest extract concentration (0.5%) resulted in 90% larval mortality, indicating a concentration-dependent increase in insecticidal activity. Lower concentrations produced reduced mortality rates, demonstrating that the efficacy of the extract increased with concentration. These findings indicate that acetone extract of M. pudica has considerable potential as a botanical insecticide for the sustainable management of S. frugiperda

Adopsi climate smart agriculture dalam mendukung peningkatan produktivitas kentang: kasus program ICARE di Kabupaten Garut

Rigan Diaz Algifari — 2026-07-29

Climate change has become one of the major challenges in potato farming development. One of the adaptation strategies promoted by the Indonesian government is the implementation of Climate Smart Agriculture (CSA). This study aimed to analyze the level of CSA and examine its implementation in supporting the improvement of potato farming productivity in Garut Regency, Indonesia. The study employed a mixed-methods approach using a concurrent embedded case study design. The respondents consisted of five farmers participating in the ICARE Program, selected through a census technique. Quantitative data were collected through field observations, questionnaires, and actual productivity data before and after CSA implementation, and were analyzed descriptively. Qualitative data were obtained through semi-structured interviews and analyzed using thematic analysis. The results showed that the cumulative adoption level of CSA innovation components was classified as high, with a score of 495 (94.29%). The average potato productivity increased from 14.6 tons/ha to 34.0 tons/ha following CSA implementation. The main factors supporting successful adoption included extension assistance, access to information, the observable benefits of innovation, and farmers' expectations of increased farm profitability. Meanwhile, the main constraints to CSA implementation included limited financial resources, restricted access to certified seeds, and the need to adapt the technology to local agroecosystem conditions. These findings indicate that the successful implementation of CSA is determined not only by technology adoption but also by effective extension services, farmer learning processes, and institutional strengthening, all of which contribute to the sustainable improvement of potato farming productivity.
