    This study evaluated the physicochemical characteristics of degraded Inceptisol and the growth performance of Barangan banana (Musa paradisiaca L.) under two soil management systems—tillage and no-till—in Seluma, Bengkulu Province, Indonesia. Field observations were conducted on a 25 ha banana plantation, with soil samples collected at depths of 0–15 cm and 15–30 cm. Plant growth measurements were taken from two representative plants per plot. Data were analyzed using a randomized complete block design (RCBD), followed by Duncan’s Multiple Range Test (DMRT) at α = 0.05. Tillage significantly improved several soil properties, including bulk density, aggregate stability, and nutrient availability. Tilled plots exhibited greater aggregate stability, higher cation exchange capacity (CEC), and increased exchangeable K and available P. The surface layer (0–15 cm) also contained higher total nitrogen and available nutrients compared with deeper soil. For plant responses, tillage enhanced plant height and pseudostem girth, suggesting better soil structure and nutrient uptake, whereas no-till plots produced more leaves. Overall, moderate tillage improved soil physical quality and nutrient dynamics in degraded Inceptisol, thereby supporting superior vegetative growth of Barangan banana. Full text pd

    KAIZEN COSTING IN DAIRY-BASED BEVERAGE MSMES AS A STRATEGY FOR COST EFFICIENCY AND PRODUCT QUALITY (A Case Study)

    Get PDF
    This empirical case study aims to examine the implementation of Kaizen Costing in improving cost efficiency and product quality in micro, small, and medium enterprises (MSMEs) engaged in dairy-based beverage production. Through an in-depth single-case study approach, this research documents the implementation process, challenges, and outcomes of Kaizen methodology application in an MSME setting in Malang City, East Java, Indonesia. The case study focuses on the MSME’s challenges in production cost control, quality consistency, and limited operational resources. A qualitative research approach was employed using a case study method involving participatory observation, in-depth interviews, and document analysis. The findings show that applying the Plan-Do-Check-Act (PDCA) cycle within the Kaizen Costing framework successfully reduced total production costs by 13% per cycle, increased work time efficiency, and reduced defective products. Process innovations such as manual pasteurization tool modifications and the use of quality control tools like the fishbone diagram also contributed significantly to improving flavor stability and product shelf life. This strategy also positively impacted consumer perception, as reflected in an 18% increase in customer satisfaction scores. Therefore, Kaizen Costing proves to function not only as a cost control method but also as a strategic approach to creating added value within the MSME supply chain. The study recommends similar MSMEs to adopt the Kaizen approach systematically to support business sustainability and enhance competitiveness in the functional dairy beverage sector

    Pengaruh Penambahan EM4 dalam Fermentasi Solid Kelapa Sawit terhadap Kualitas Nutrisi Bahan Pakan: The Effect of EM4 Addition in Palm Oil Solid Fermentation on the Nutritional Quality of FeedIngredients

    Get PDF
    This study aims to evaluate the effect of the addition of Effective Microorganisms-4 (EM4) on changes in the proximate composition of palm oil solids during the fermentation process. The study design used EM4 treatments with different concentrations (0%, 0.5%, 1.0%, and 1.5% stored for 14 days. The parameters observed included moisture, ash, protein, fat, and crude fiber content. The results showed that moisture and ash content tended to decrease with increasing EM4 concentration and fermentation time. Protein content decreased significantly in the EM4 treatment compared to the control, indicating the utilization of organic nitrogen by microorganisms. Conversely, fat content increased in the 1.5% EM4 treatment, presumably due to the activity of lipolytic enzymes and microbial lipid biosynthesis. Crude fiber content showed a decreasing trend in the EM4 treatment, reflecting the degradation of cellulose and lignin by cellulolytic enzymes. Overall, the addition of EM4 can improve the nutritional quality of palm oil solids by reducing crude fiber and complex proteins and increasing the fat fraction at certain concentrations, so it has the potential to be used as an alternative feed ingredient for poultr
