Abstract

This study aims to analyze the production efficiency of Melte Vanana banana chips agroindustry through the calculation of COGS using the full costing method, BEP analysis, and mapping the marketing structure applied by CV. Vanana Jaya Sinergi in Bandar Lampung City. The study was conducted in January 2025 using a mixed methods approach integrating quantitative and qualitative analysis. Data were collected through semi-structured interviews, participatory observation, and documentation involving eleven respondents directly engaged in the production and marketing chain. The sampling method applied was purposive sampling based on the respondents’ direct involvement in the production and marketing processes. Data validity was ensured through triangulation of sources and methods. The results showed that COGS per package varied across flavors: Vanilla Milk (IDR 4,696), Green Tea (IDR 5,014), Yummy Chocolate (IDR 5,656), Coffee Latte (IDR 5,788), and Cheese Melt (IDR 5,868), with a uniform selling price of IDR 10,000/unit, generating profit margins ranging from 41% to 53%. The overall Gross Profit Margin (GPM) reached 57.2%, exceeding the average of similar micro, small and medium enterprises. All product variants operated above the BEP with significant margins of safety. The marketing structure operated through three tiers distributors, agents, and resellers with a farmer share of 66.7%, indicating an efficient marketing channel. This study concludes that Melte Vanana agroindustry has achieved good production and marketing efficiency. A key limitation is the concentration of raw material supply (78%) on a single supplier, which poses a significant supply chain risk. Future research is recommended to incorporate BEP sensitivity analysis and broader multi-period data.

Abstract

The objective of this study was to evaluate the growth response, feed utilization efficiency, and survival rate of Sangkuriang catfish (Clarias gariepinus) that were fed diets supplemented with various doses of a synbiotic formulated from Rabal probiotics and sweet potato extract. The 60-day experiment used a completely randomized design (CRD) with three synbiotic dosage treatments: P1 (5%), P2 (10%), and P3 (15%), with four replicates per treatment. The study focused on comparing growth responses among synbiotic dosage levels and did not include a control treatment without synbiotic supplementation (P0). Therefore, the results could only be interpreted in terms of comparisons among the tested synbiotic doses. Observed parameters included weight gain, length gain, feed efficiency, feed conversion ratio (FCR), and survival rate. The results showed that different synbiotic doses produced significantly different growth responses (p < 0.01). The highest growth performance was obtained in the P3 treatment (15% synbiotic), resulting in the greatest weight (25.75 ± 0.20 g) and length (8.31 ± 0.02 cm) gains. Feed efficiency increased, reaching 0.80 in P3, while the FCR decreased to 1.29. However, the differences in feed efficiency and FCR among the treatments were not statistically significant (p > 0.05). The survival rate remained high, reaching 100% in all treatments. These findings suggest that higher synbiotic doses tend to produce better growth performance within the tested dosage levels while maintaining a high survival rate and comparable feed utilization efficiency in Sangkuriang catfish.

Abstract

Variations in land-use types and management intensity significantly alter soil physical-chemical properties and dictate carbon dioxide (CO2) emissions fluxes. This study aimed to model the control of soil physical-chemical characteristics on soil CO2 emission rates across various tropical mineral land-use types in Seginim District, South Bengkulu Regency. Utilizing an observational edaphic dataset across six dominant land-use types (corn, oil palm, natural forest, vegetables, coffee, and rubber) with three replications (N=18), advanced statistical modeling via Pearson correlation and multiple linear regression was performed. Soil CO2 emissions were measured in-situ using the modified closed-chamber method followed by alkali absorption titration, while edaphic variables (soil moisture, temperature, bulk density, and pH) were evaluated using standard laboratory procedures. Data were analyzed using Pearson correlation and multiple linear regression. The results revealed that intensive land-use types, namely corn (51.65 ± 2.31 kg/ha/day) and vegetables (43.80 ± 2.75 kg/ha/day), doubled CO2 emissions compared to natural forest (21.87 ± 1.36 kg/ha/day). Soil moisture and bulk density acted as the master variables controlling the emissions. Soil moisture alone showed a strong negative correlation, explaining 83.72% of the emission variance (r = -0.91; p < 0.01). Integrating all edaphic components into a multivariate regression model significantly increased the predictive power to 97.22% (R2 = 0.9722; p < 0.001), driven by the severe physical inhibition effect of bulk density (β = -30.83; p < 0.001). Conversely, soil temperature and pH exerted no significant partial effects due to microclimatic buffering. This study concludes that soil physical properties rigidly govern CO2 emissions across different tropical mineral land uses. Consequently, climate change mitigation strategies must prioritize protecting soil physical structures through water management and compaction prevention rather than chemical manipulation.
