Abstract

Along with the development of industry and the increase in population, the need for chilies has also increased. This shows that more than half of the chilies that have been harvested have the potential to be wasted or not utilized optimally. So the dryer designed and made is a type of bulb heat-based dryer, namely a chili dryer that can use heat energy from the light rays of the bulb. With this dryer, it is hoped that there will be an increase in production capacity. Apart from that, the product obtained will be of good quality, namely having relatively clean chili quality. The research design used in this research is to use one treatment, namely for 10 hours from 08:00-18:00 and testing the specified parameters at a time interval of 120 minutes. In this research, the method used was an average calculation with one treatment repeated 3 times, symbolized P1= chili product 1, P2= chili product 2, P3= chili product 3. Bulb heat-based dryers can work well according to their use. This tool produces an average temperature of 52.44°C, and the highest temperature reaches 60°C. The capacity of this bulb heat-based dryer has 6 shelves and can accommodate 4,800 g of chili, with each shelf able to accommodate 800 g of chili.. Based on tests on the parameters that have been carried out, the average water content in chilies is 57.3354%. This result is still very high compared to the SNI for the water content in dried chilies of 11%.

Abstract

Red palm oil is a palm oil derivative product, where refining is simple without a bleaching process, so it has good nutritional content (carotenoids or as pro-vitamin A, vitamin E, tocopherols and tocotrienols), and also provides health benefits. However, there is no information on processing red palm oil by choosing a better separation method to produce red oil with maximum yield but still good quality. This research was carried out using 2 separation methods, namely centrifugation and sedimentation. The treatments consisted of different temperatures used during the process of homogenizing CPO (3 temperature variations), including P1 = 80℃, P2 = 70℃ P3 = 60℃. This research used a CRD. From the results of the studies, it was concluded that difference in fractionation method and temperature indeed had some effects on the yield and quality of red palm oil. Furthermore, the best yield results during the study were obtained by centrifugation at 80°C temperature The yield was 69% and the quality characteristics were free fatty acid content of 2.78%, water content of 1.61%, DOBI value of 2.03, and beta-carotene content of 423.05 ppm.

Abstract

This research aims to synergize local microorganisms (LMO) of golden snails (Pomacea canaliculata) and seed age in optimizing rice seed germination (Oryza sativa L.). Golden snail LMO, which is rich in organic nutrients and beneficial microorganisms, has the potential to improve seed quality and viability. The study used a factorial randomized block design (RBD) with two factors: golden snail LMO concentration (Control, 20 ml/L water, 40 ml/L water) and seedling age (7 days, 11 days, and 15 days after sowing). The variables observed included seed germination, simultaneity grows and growth speed. The results showed that the golden snail LMO concentration of 20 ml/L and seed age of 11 days after sowing gave the highest results for the observed variables, namely seed germination and growth speed while the interaction between golden snail LMO concentration mas 40 ml/L and seed age of 15 days after sowing gave the highest results for the variable observing growth synchrony. The combination of the two factors showed a positive interaction that supported the germination process effectively. This study concludes that the use of golden snail LMO and selecting the right seed age can be an ecological and efficient approach to increasing rice seed productivity, supporting sustainable agriculture.

Abstract

This study examines the characteristics of water absorption and load-bearing resistance of coconut coir–based cocopot with different thicknesses as an environmentally friendly planting medium. Cocopots were produced from a mixture of cocofiber, cocopeat, and latex adhesive with three thickness variations: 1.0 cm, 1.5 cm, and 2.0 cm. Water absorption was evaluated using a 5-minute immersion test, while load-bearing resistance was assessed by repeatedly dropping soil-filled cocopots from a height of 3 meters under a total load of 1,096 g. The results show a consistent trend indicating that increased thickness is associated with higher water absorption capacity and improved mechanical durability. Cocopots with a thickness of 2.0 cm exhibited the highest water absorption (90–91%) and the lowest damage level, with a Load-Bearing Resistance Index of 0.55–0.58%. In contrast, cocopots with a thickness of 1.0 cm showed the lowest performance. These findings suggest that thicker cocopots provide better functional characteristics for agricultural applications.

Abstract

Sagon cake is a traditional Indonesian food that can be further developed through the utilization of coconut pulp as a value-added raw material. This study aimed to analyze the effect of different sugar types on the chemical and organoleptic characteristics of coconut pulp sagon cake. A Completely Randomized Design (CRD) with one factor and three treatments was applied, namely palm sugar (P1), corn sugar (P2), and coconut sugar (P3), with three replications each. The observed parameters included moisture content, ash content, and organoleptic properties (color, aroma, texture, and taste). Data were analyzed using Analysis of Variance (ANOVA) followed by the Least Significant Difference (LSD) test at the 5% significance level. The results showed that sugar type had a highly significant effect on moisture content (p<0.01) and a significant effect on ash content, color, aroma, and taste (p<0.05), while no significant effect was observed on texture (p>0.05). Coconut sugar treatment produced the lowest moisture content (2.53%) and the highest ash content (1.20%). In the organoleptic evaluation, palm sugar obtained the highest preference scores for color (4.00), aroma (4.28), and taste (4.00), whereas coconut sugar achieved the highest score for texture (3.57). All treatments complied with the quality requirements of SNI 01-4475-1998 for moisture and ash content. The results indicate that coconut sugar has the potential to improve product storage stability due to its lower moisture content compared with the other treatments.
