Penelitian ini bertujuan untuk mengukur kualitas sebuah rancangan pengering hybrid yang menggunakan dua sumber energi, yaitu sekam sebagai sumber pemanas dan panas surya. Alat didesain dapat digunakan pada kondisi cuaca panas dan dingin, karena alat dilengkapi dengan dua sumber pemanas yang bisa beroperasi dengan menggunakan sumber pemanas tunggal maupun sumber pemanas ganda. Pengamatan dilakukan dengan cara menghitung berat sampel cabe yang dikeringkan dengan pemanas sekam dan pemanas surya. Pengamatan berat dilakukan tiap jam. Dari hasil penelitian menunjukkan bahwa alat ini dapat digunakan untuk mengeringkan cabai secara efisien. Alat ini dapat bekerja sepanjang hari serta cepat dalam kinerja pengeringan. Selain itu, alat ini juga bersih dan aman dari hujan. Jika alat ini digunakan menggunakan sistem tunggal, maka kinerja alat menggunakan tenaga surya adalah lebih baik jika dibandingkan dengan menggunakan pemanas dengan bahan bakar sekam. Hal ini dilihat berdasarkan rata-rata suhu yang dihasilkan selama 9 jam (43,17 °C berbanding 37,89 °C), perubahan berat sampel setelah pengeringan selama 6 jam (73,7 gram berbanding 92,0 gram dari berat awal 100 gram) serta jumlah kehilangan air setelah pengeringan selama 6 jam (26,3% berbanding 8%).

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%.

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.

Skimmed coconut milk is a by-product of the coconut processing industry which is still underutilized. Apart from being worthless, skimmed coconut milk that is thrown into the environment can cause pollution. Therefore, innovation is needed so that skimmed coconut milk can be utilized into a product with high selling value. One product that can be produced by utilizing skimmed coconut milk is nata de coco. This research aims to analyze the effect of differences in sugar content contained in the substrate mixture of skimmed coconut milk and coconut water (50:50) on the yield, thickness and sensory properties of the nata de coco produced. The research design used in this study was a Completely Randomized Design (CRD), with 1 treatment factor, namely differences in sugar content (P1 = sugar content 2.5%, P2 = 7.5%, P3 = 12.5%). As a control (K), the substrate was used in the form of pure coconut water with a sugar content of 3%. From the research results it was found that Control (K) produced a yield of 76.9%, P1 of 53.7%, P2 of 62.2%, and P3 of 45.7%, however the results of statistical tests stated that the difference in these values was not significant. The results of the nata de coco thickness test showed that Control (K) produced nata with the highest thickness (11.4 mm), while P2 produced the higher thickness (8.8 mm) compared to other treatments that used a mixture of coconut water and skimmed coconut milk as a substrate (P1 and P3). The results of the hedonic test showed that differences in sugar content (P1, P2, P3) did not have a significant effect on the liking value of the nata de coco produced, where all values were in the "rather like" range, both in the color, texture and taste.

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.
