Abstract

Coffee drying is a crucial stage that influences the final product's quality and flavor. This process must be performed correctly to maintain the quality of the coffee beans and prevent mold growth. This study aims to compare two coffee drying methods, using a Solar Dome Dryer and direct sun drying. The research was conducted in Karang Sidemen Village, Central Lombok, using 100 kg of coffee beans, divided into two groups of 50 kg each for the two drying methods. The results showed that both methods successfully reduced the moisture content to 0%, but the drying with the Solar Dome Dryer was faster (4,320 minutes) compared to direct sun drying (4,380 minutes). The Solar Dome Dryer maintained a more stable temperature (50-60°C) and produced a more consistent drying rate, making it more efficient in preserving the quality of the coffee beans and preventing microbial contamination. This study recommends the use of Solar Dome Dryer for coffee drying in areas with high humidity and variable weather conditions.

Abstract

High ambient temperatures inside tropical greenhouses can significantly raise nutrient solution temperatures in vertical hydroponic systems, disrupting nutrient uptake and reducing plant productivity. This study focuses on the design and development of a nutrient cooling system (chiller) using two TEC1-12706 thermoelectric modules (Peltier) arranged in series to enhance heat dissipation performance. The nutrient solution is pumped from the reservoir to the cooling chamber using a 12 V DC pump and recirculated in a closed-loop configuration. The chiller system is fully automated, controlled by two DH48S digital timers operating simultaneously: one activates Peltier 1, while the other controls Peltier 2 via the NC output (5 minutes) and the pump via the NO output (30 seconds), enabling alternating programmed cooling and circulation. The entire chiller unit is active only from 08:00 to 18:00 WITA using a KG316T programmable timer, corresponding to peak thermal stress hours inside the greenhouse. Results showed that despite greenhouse temperatures reaching up to 39.4 °C with relative humidity dropping to 47.6%, the chiller system maintained nutrient solution temperatures within the optimal 27–30 °C range. This design proved effective in reducing and stabilizing nutrient temperature under high heat microclimates. With its simple, automated, and energy-efficient architecture, the chiller system offers a promising solution for small-scale vertical hydroponics and greenhouse-based urban farming in tropical regions.

Abstract

Stunting remains an unresolved issue in North Lombok, NTB, Indonesia. One of the government's efforts to reduce stunting rates involves ensuring nutritional fulfillment for mothers and expectant mothers, which can be obtained from local food sources. Nira (palm sap) and Trigona honey are local commodities available in Tanjung, North Lombok. Unfortunately, these commodities have not been optimally utilized for nutritional fulfillment or as income sources. Typically, Nira is only sold as fresh sap, fermented beverage (tuak), or palm sugar, which have relatively low market values. Combining Nira and Trigona honey to create high-value candy products represents an opportunity. This community service project aimed to improve welfare and nutrition in Sigar Penjalin Village by assisting in the production of hard candy from Trigona honey and Nira Aren as a potential local delicacy to combat stunting and enhance local income. The implementation involved 16 community members organized by UMKM Rangsot Kreatif. The training used ingredients like brown sugar, granulated sugar, glucose syrup, Trigona honey, and water. The training stages included preparation, material delivery, hands-on practice, and evaluation through pretests and posttests to measure participants' knowledge, skills, and interests. The pretest results showed a total score of 627 out of 960 (65.31%), indicating a moderate level of understanding. After the training, the posttest showed a significant improvement, with a total score of 829 out of 960 (86.35%), indicating a very high level of understanding. This activity highlights the importance of technological support and the utilization of local resources in developing nutritious and economical snack products, supporting improvements in community nutrition and economy, and providing alternative solutions in local product processing

Abstract

The growing medium should have good water-holding capacity as it is essential for root growth. Roots need water to absorb nutrients and oxygen from the growing medium. Too much water can cause the roots to rot, while too little water can cause the roots to dry and die. Plants also absorb nutrients from the growing media through water. It is important to know the physical characteristics of planting media from organic waste from bamboo crafts and aren fronds as hydroponic growing media. The addition of cocopeat as a component of growing media offers a number of significant advantages, this is because cocopeat has an exceptional ability to retain water, which is essential for maintaining consistent moisture around plant roots. In addition, the porous structure of cocopeat improves aeration, allowing oxygen to reach the roots and preventing root rot. The slightly acidic to neutral pH properties of cocopeat (pH 5.0-6.8) are also ideal for most plants, creating an environment conducive to nutrient absorption. The results obtained physical characteristics of bamboo craft waste and palm fronds by adding cocopeat as a hydroponic growing medium have water content, bulk density, porosity and water holding capacity (WHC) values respectively 81.81%, 0.189 gr/cm3, 74.6%, and 450% for bamboo craft waste and 102.34%, 0.176 gr/cm3, 68.7% and 622% for palm fronds. Based on these results, it can be concluded that bamboo craft waste and palm fronds with the addition of cocopeat have high water content and are good for plant growth.
