Abstract

This study aimed to analyze the marketing efficiency of buffalo livestock in the cultural context of Kodi, Kodi Bangedo District, Southwest Sumba Regency. The research used a mixed-methods approach (quantitative and qualitative) through surveys of 30 farmers, in-depth interviews with traditional leaders and stakeholders, and field observations. The results show that the total marketing value from producers was IDR 1,521,000,000 (98 heads), and the end consumers' purchase value was IDR 1,661,000,000, resulting in a marketing margin of IDR 140,000,000. The average marketing efficiency rate was 27.99%, indicating the marketing system is not yet optimal. Kodi culture plays a significant role in determining distribution patterns and price mechanisms, where transactions are still dominated by social relationships and local networks. This study recommends developing shorter marketing channels and integrating cultural values into marketing strategies to improve farmers' economic efficiency.

Abstract

The development of the agro-industry in Batu City has spurred the growth of Micro, Small, and Medium Enterprises (MSMEs), including those involved in tempeh processing. However, many MSMEs have not conducted comprehensive financial feasibility assessments to ensure business sustainability. This study aimed to analyze the financial feasibility of the tempeh processing business at UMKM Rizky Jaya and test its resilience to cost fluctuations through sensitivity analysis. Data were collected through in-depth interviews, field observations, and document studies. A Feasibility analysis utilized indicators such as Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP), Break-Even Point (BEP), and Revenue Cost Ratio (R/C). The business generates an annual net profit of IDR 262,645,791 with an NPV of IDR 607,995,760 (at a 10% discount rate), IRR of 90%, PP of 389 days, BEP of 10,395 units, and R/C Ratio of 1.35. The tempeh processing business at UMKM Rizky Jaya is financially viable and shows strong resilience to market fluctuation risks. This study recommends the need for product diversification and technology utilization to enhance long-term competitiveness.

Abstract

This study aimed to examine the influence of financial literacy on the resilience of food-sector MSMEs (Micro, Small, and Medium Enterprises), with fintech adoption as a supporting variable, to address the research gap concerning the interaction between financial competence and technology adoption in the context of economic digitalization. A quantitative survey of 50 food-sector MSME actors in Blitar City who have used fintech services was analyzed using multiple linear regression. The results indicate that financial literacy has a significant and strong influence on business resilience (? = 0.47; p 0.01), while fintech adoption has a positive but more moderate effect (? = 0.22; p 0.05). The model explains 45% of the variance in MSME resilience. These findings reinforce the resource-based view theory by affirming that internal capability (financial literacy) is a key resource that is enhanced by technology (fintech) to build resilience. The implication is that MSME empowerment programs should integrate financial training with guided adoption of digital technology in a comprehensive manner

Abstract

This study profiles the phenotypic characteristics and production performance of Peranakan Ongole (PO) bulls in Bojonegoro Regency, an officially designated PO cattle breed-source site, and evaluates their capacity to support sustainable community-based breeding. A descriptive-quantitative survey was conducted over two months in three subdistricts (Tambakrejo, Sekar, and Kedungadem), selecting 180 purposively sampled bulls aged ≤50 months. Primary data comprised qualitative (coat color, horn shape, ear hair pigmentation, and other SNI–specified traits) and quantitative (heart girth, body length, height at rump) phenotypic measurements; secondary data on birth, weaning, and one-year body weights were obtained via farmer questionnaires, key-informant interviews, and official records. Descriptive statistics revealed that all sampled bulls met SNI qualitative standards, with the sole exception of progressive ear-hair graying in mature animals. Quantitative traits consistently exceeded Class I SNI minimum (such as mean chest girth 163–191 cm; body length 130–158 cm; withers height 130–141 cm). Mean production weights were 20.0 ± 3.3 kg at birth, 116.5 ± 9.0 kg at weaning, and 138.3 ± 13.6 kg at one year, surpassing or matching earlier reports. Observed genotype, environment synergy, driven by abundant local forage and traditional management, underscores the bulls’ preserved genetic merit and breeding potential. These findings furnish a strategic basis for selective male choice and policy interventions to enhance PO genetic improvement and breeder livelihoods in Bojonegoro.

Abstract

Goat and sheep farming in Tulungagung Regency plays a crucial role in rural livelihoods, yet it still faces economic vulnerability, institutional limitations, and environmental pressures. Furthermore, studies on sustainability, which link livelihood assets to business performance at the local level, are still limited. This study aims to assess the level of livelihood and business sustainability among farmers and identify key livelihood assets that influence business resilience. Data were collected from 73 farmers through structured questionnaires and analysed using an ordinal scoring method (1–3) for 14 indicators grouped into five livelihood assets and three dimensions of sustainability (economic, social, and environmental). The results show that 49.32% of farmers have achieved the sustainable livelihood category, while 54.79% of businesses remain in the moderately sustainable category. The environmental dimension shows the best performance, and the economic dimension is the weakest, due to low income, limited access to capital, and price fluctuations. The main obstacles faced include livestock diseases, limited feed, and lack of institutional support. It can therefore be concluded that the sustainability of goat and sheep farming businesses in Tulungagung is still relatively fragile and requires strengthening in economic and institutional aspects, particularly through increased access to capital, feed provision, and strengthening of marketing institutions.

Abstract

Red sorghum (Sorghum bicolor L.) is a promising local food resource in Indonesia, but its utilization is hindered by its inherent bitterness, primarily caused by tannins. This study aimed to reduce bitterness and improve functional properties through fermentation using Lactobacillus plantarum. A Randomized Block Design with two factors—inoculum concentration (3 levels) and fermentation time (3 levels)—was applied, resulting in nine treatments. The tannin content, protein digestibility, solubility, swelling power, and water absorption capacity were analyzed. Fermentation significantly reduced tannin content by up to 60% (p 0.005) and increased protein digestibility from 45% to 70%. Simultaneously, solubility, swelling power, and water absorption capacity improved from 33.45% to 55.87%, 7.28 g/g to 9.05 g/g, and 11.92% to 13.68%, respectively. Optimal results were obtained after 48 hours of fermentation. These findings demonstrate that L. plantarum fermentation effectively mitigates bitterness while enhancing nutritional and functional qualities, offering a viable processing method to promote red sorghum as a functional food ingredient and support food diversification strategies in Indonesia. Further research should focus on sensory evaluation and application in food product development.

Abstract

Polyploidy induction is a plant breeding strategy to improve agronomic traits. This study aimed to examine the effect of colchicine concentration and immersion duration on the morphological, phenological, and production characteristics of cayenne pepper (Capsicum frutescens L.). The experiment used a Factorial Randomized Block Design with two factors: colchicine concentration (0, 10, 20, 30 ppm) and immersion duration (12, 24 hours), replicated four times. Data were analyzed using two-way ANOVA and the least Significant Difference (LSD) test at ?=5%. The results showed a significant interaction between both factors on plant height, leaf area, flowering time, fruit length, and flesh thickness. The 30 ppm colchicine with 24-hour immersion (K3W2) produced the widest leaves (7.98 cm) but delayed flowering initiation to 80 days after planting (DAP). The highest yield (7.2 tons/ha) was achieved at K3W2, showing a 92% increase compared to the control. Indicated polyploidy resulted in shorter fruits (4.32 cm) but with larger diameter (1.35 cm), thicker flesh (0.044 cm), and fewer seeds (53.75 seeds/fruit). It is concluded that 30 ppm colchicine effectively induces polyploid phenotypic changes in cayenne pepper, increasing yield but reducing generative fertility.

Abstract

Cilok is a traditional snack food made from tapioca flour with limited nutritional value. Diversification with chicken meat and sweet potato flour has the potential to enhance the nutritional and functional value of the product, particularly as a source of natural antioxidants. This study aimed to analyze the effect of variety (yellow, purple, and white) and concentration (10% and 20%) of sweet potato flour on the antioxidant activity and sensory characteristics (color, aroma, taste, and texture) of chicken cilok, and to determine the optimal formulation. The experimental design used a Randomized Block Design (RBD) with 7 treatments and 3 replications. Antioxidant activity was analyzed using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method, while sensory evaluation was conducted using a hedonic scaling method (scale 1–7) involving 20 semi-trained panelists. Data were analyzed by ANOVA and further tested with LSD at ?=0.05, while sensory data were analyzed using the Friedman test. The result showed that concentration and variety of sweet potato flour had a significant effect (p0.05) on antioxidant activity and a highly significant effect (p0.01) on all sensory attributes. The highest antioxidant activity was obtained in treatment P5 (80% chicken meat + 20% purple sweet potato flour) at 7.040 ± 0.30% (DPPH radical scavenging activity). The same treatment also received the highest overall sensory scores (color: 6.53; aroma: 5.57; taste: 5.82; texture: 5.40) and was selected as the best formulation based on the effectiveness index analysis. The addition of 20% purple sweet potato flour can increase antioxidant activity and is sensorily acceptable, thus having potential to be developed as a functional chicken cilok.

Abstract

 Shallot farming on marginal land with an ultra-small scale (0.1 ha) faces different efficiency and profitability challenges compared to larger-scale farming. This study aims to analyze the cost structure, income, financial feasibility, and break-even point of ultra-small-scale shallot farming in Air Duku Village, Rejang Lebong Regency. Using a quantitative descriptive method with a case study approach, this research involved 12 farmers selected through purposive sampling based on the criteria of actively cultivating shallots for at least two growing seasons on 0.02-0.08 ha of land. Data were collected through structured interviews and analyzed using income analysis, R/C ratio, and Break-Even Point (BEP) analysis. The results showed that the average production cost was IDR 4,479,187.48 per growing season, with a net income of IDR 5,920,812.52. An R/C ratio of 1.32 indicates that this farming practice is financially feasible and profitable. The production break-even point was achieved at 172.28 kg, far below the actual production (400 kg). Similarly, the sales break-even point (IDR 4,479,187.48) was below the actual revenue (IDR 10,400,000). These findings confirm that ultra-small-scale shallot farming still has promising economic prospects and a low risk of loss, although there is room for improvement in input use efficiency, particularly in terms of seed and labor utilization. The policy implication of this research is the need for technical assistance to optimize the productivity of smallholdings and improve farmer access to more efficient production inputs

Abstract

The use of natural growth regulators offers a sustainable alternative to synthetic compounds in hydroponic systems. This study evaluates the effect of natural plant growth regulators (PGRs) from coconut water and bamboo shoot extract on the growth of green lettuce (Lactuca sativa L.) in a Deep Flow Technique (DFT) hydroponic system and determines the optimal concentration. The experiment, conducted at BPSIP from October to November 2024, used a Completely Randomized Design (CRD) with nine treatments: a control, coconut water, and bamboo shoot extracts at concentrations of 10, 20, 30, and 40 ml L?¹, with three replications. The results showed that PGR applications did not significantly affect most parameters, including plant height at 21 and 35 days after transplanting (DAT), leaf dimensions, fresh shoot weight, and root weight. However, significant effects were observed on plant height at 28 DAT and leaf number at 28 and 35 DAT. Coconut water at 10 ml L?¹ produced the best response for these parameters. These findings confirm that the effectiveness of natural PGRs in DFT hydroponics is concentration-dependent and that under optimal nutrient conditions, their addition does not consistently enhance lettuce growth.
