Abstract

Virgin Coconut Oil (VCO) is becoming increasingly popular as public awareness of the importance of health through the use of natural ingredients increases.  The fatty acids and antioxidants in VCO make a major contribution to body health. The nutritional content of the VCO produced is influenced by the processing method.   The purpose of this study was to determine the duration of standing coconut cream after being frozen which can produce VCO with high yield, lowest water content, and most preferred by consumers. The research method used was an experimental method using the treatment of the duration of standing of coconut cream (12 hours, 18 hours, and 24 hours). The parameters observed included yield, water content and consumer acceptance including aroma, color, taste, viscosity and rancidity of VCO produced using 30 semi-trained panelists. The results showed that the duration of standing coconut cream significantly affected the yield and water content. A standing time of 18 hours can provide the best VCO results based on yield (30.33%), water content (0.18%), and consumer acceptance of aroma, color, taste, viscosity, and rancidity on a scale of liking.

Abstract

Fishing activities that occur in this market produce waste water that still contains pollutants with concentrations above quality standards. This causes the waste water to smell bad and have high turbidity. Planning a liquid waste processing system in a market is needed to improve the quality of the air that will be discharged so that it does not pollute the environment. This research is about planning a Waste Water Treatment Plant (IPAL) network system at the fish marketing site at the Ternate fishing port. From this research, we will know the design of the Waste Water Treatment Plant System and also the Cost Budget Plan (RAB) for the planning of the IPAL. From the results of the analysis of waste water discharge calculations at the Ternate fisheries market with a total of 40 selling table units producing waste water, namely, 3,333 liters/day. So an IPAL can be designed with a length of 6.1 m, a width of 1.8 m and a height of 1.65 m. The planning for the Fishery Market Wastewater Treatment Plant has 6 compartments, namely, Screen tank or Oil/Fat Separator Tank which has a volume of 0.16 m3/day => Equalization tank has a volume of 1.4 m3/day => Initial sedimentation tank has a volume of 1 .2 m3/day => Anaerobic Biofilter tank has a volume of 1.1 m3/day => Aerobic Biofilter tank has a volume of 1.4 m3/day => Final settling tank has a volume of 0.18 m3/day. The budget required for implementing the planning for the Waste Water Treatment Plant (IPAL) at the Fisheries Market is IDR. 86,009,000.00.

Abstract

This study investigates the influence of agricultural facilities and infrastructure on farmer behavior in managing lowland rice farming in Kondamara Village, Lewa Subdistrict, East Sumba Regency, using the COM-B model (Capability, Opportunity, Motivation–Behavior). A quantitative approach was employed through Structural Equation Modeling–Partial Least Squares (SEM-PLS), with data collected from 100 farmers via structured questionnaires and field observations. The results reveal that agricultural infrastructure—such as irrigation systems, farm roads, and farmer groups—has a significantly stronger impact (path coefficient = 0.766; f² = 2.292) on farmer behavior than mechanized facilities (path coefficient = 0.219; f² = 0.187). The model's high predictive accuracy is demonstrated by an R² value of 0.852. These findings underscore the strategic importance of developing agricultural infrastructure and empowering farmer groups as key interventions to foster adaptive and sustainable farming behavior, particularly in food-insecure rural areas.

Abstract

Candidiasis is an infection caused by the fungus Candida albicans and can attack various parts of the body such as skin, hair, nails, mucous membranes, and internal organs. The use of synthetic antifungal drugs is common in treating this infection, but causes unwanted side effects, therefore alternative treatments based on natural ingredients are needed that are safer and more effective. Garlic (Allium sativum) and turmeric (Curcuma longa) contain bioactive compounds such as allicin and curcumin which have the potential as antifungal agents. The purpose of this study was to determine the effectiveness of garlic (Allium sativum) and turmeric (Curcuma longa) extracts in inhibiting Candida albicans fungus. This study used 3 treatment groups, namely the control group, the garlic (Allium sativum) and turmeric (Curcuma longa) groups with each extract concentration of 20%, 40%, 60% and 80% with six repetitions. Extraction using maceration method with 96% ethanol solvent, while antifungal activity test was conducted using disc diffusion method on Sabouraud Dextrose Agar (SDA) media. Inhibition zone was observed after incubation for 24 hours in an incubator with a temperature of 37 °C. The results showed that garlic and turmeric extracts did not produce inhibition zone against Candida albicans growth. This ineffectiveness was caused by several factors, including the processing of materials, the use of high concentration ethanol solvent, testing method, and the absence of quantitative analysis of active compound content. These factors affect the decrease in the effectiveness of active compounds in the extract, so that it is unable to inhibit the growth of Candida albicans.
