Abstract

Oyster mushrooms (Pleurotus ostreatus) require a humid environment and stable temperatures to grow optimally. One of the mushroom growing media, namely mushroom house, which need to be regulated in temperature and humidity in order to produce high-quality mushrooms. Management of environmental conditions is essential, as significant changes in temperature and humidity can inhibit mold growth or even cause disease. This study aims to monitor the internal and external conditions of the oyster mushroom growing environment using a DHT11 sensor so that ideal growth conditions can be obtained. This research was carried out through several stages, including the preparation of tools and materials, hardware design, layout arrangement, testing of temperature and air humidity control systems, and monitoring oyster mold growth. The results of the 20-day study showed that the internal temperature in oyster mushroom clusters was at the ideal temperature for oyster mushroom growth, which ranged from 25,3°C to 30,8°C, while the maximum humidity reached up to 98% at certain times. The external temperature of mushroom house is in the temperature range of 28°C to 33,5°C with a relatively lower humidity, ranging from 73,2% to 91,2%. Humidity above 90% dominates most measurements, especially in the afternoon, creating ideal conditions for mold growth. The use of the DHT11 sensor in temperature and humidity measurements in this study was effective in recording significant daily fluctuations. The resulting data shows that the sensor is able to detect changes in temperature and humidity of the kumbung chamber and the environment.

Abstract

The success rate in the seedling process is ofte hampered by inappropriate watering, which can cause the seedlings to rot and die. To overcome this problem, an efficient watering system with a high degree of precision is required. Mist irrigation is one of the appropriate methods because micro-sized water droplets are sprayed to maintain air humidity and reduce the rate of transpiration. This study aims to optimize the application of mist irrigation by evaluating the effect of nozzle height variations on plant growth. Using an experimental method, the variations included nozzle heights of 20 cm, 25 cm, and 30 cm. The parameters measured in this study included water discharge, plant height, number of leaves, and leaf area. The results showed that a watering height of 25 cm produced the best plant growth. The results of this study show that specific adjustment of the nozzle height is very important for improving the efficiency of mist irrigation in the seedling process. Keywords: mist irrigation, seedling, green mustard

Abstract

Proper post-harvest handling is very necessary to maintain product quality and extend the shelf life. One way to extend the shelf life of agricultural products, including cayenne pepper (Capsicum frutescens L.), is by drying techniques. Blanching pretreatment before drying can maintain the condition of the dried product so that it can maintain the final product quality. The aim of this research was to analyze the water content, water content ratio (MR), drying rate, drying constant of cayenne pepper using a rotary rack type of hybrid dryer. The use of rotary racks type hybrid dryer is a cheaper drying alternative and the use of rotary racks is able to standardize the water content in the cayenne pepper drying process. The research was carried out with two treatments, namely with and without blanching process at a temperature of 90°C for 5 min. The second factor was drying temperatures were are 43 47℃, 48-52℃ and 53-57℃ until the cayenne pepper reach the water content according to the reference, namely in the range of 5-8%. From the research results, it was obtained that the lowest water content of cayenne pepper was given pretreatment blanching at a temperature of 53-57°C, namely 6.43% with a drying time of up to 14 h. The drying rate of blanched cayenne pepper was higher than that of unblanched cayenne pepper. Keywords: Blanching, Cayenne pepper, Drying.

Abstract

Pengemasan dan transportasi buah segar menghadapi tantangan ganda: tingginya kerugian pascapanen (40-50%) dan dampak lingkungan dari kemasan plastik konvensional. Kajian literatur ini mengeksplorasi solusi inovatif dengan menganalisis pemanfaatan gulma air (seperti eceng gondok) dan limbah pertanian (seperti kulit pisang dan ampas tebu) sebagai bahan baku kemasan berkelanjutan melalui pendekatan filsafat ilmu. Secara ontologis, hakikat limbah diubah dari bahan tak berguna menjadi sumber daya bernilai yang kaya biopolimer seperti selulosa dan pektin. Validasi epistemologis dilakukan melalui metode empiris, termasuk sintesis material (misalnya, hidrogel dari eceng gondok), pengujian kinerja mekanis, dan Analisis Siklus Hidup (LCA). Hasilnya menunjukkan bahwa material berbasis limbah ini menawarkan kinerja perlindungan yang kompetitif—terbukti mampu mengurangi kehilangan berat, mempertahankan kekerasan, dan meningkatkan retensi warna pada buah selama transportasi. Keunggulan utamanya terletak pada sifat biodegradable, yang dikonfirmasi melalui pengujian penguburan tanah dimana material mengalami pengurangan massa signifikan. Secara aksiologis, inovasi ini memberikan nilai keberlanjutan yang luas. Dengan mendukung ekonomi sirkular, mengurangi polusi plastik, dan meminimalkan kerugian pascapanen, pendekatan ini sejalan dengan Tujuan Pembangunan Berkelanjutan (SDG) 12. Disimpulkan bahwa pemanfaatan limbah untuk kemasan buah tidak hanya layak secara teknis, tetapi juga memiliki landasan filosofis yang kuat untuk menciptakan sistem transportasi buah yang lebih berkelanjutan dan bertanggung jawab secara lingkungan.

Abstract

Arenga sap is the primary raw material utilized by the community of Giri Madia Village, predominantly processed into conventional palm sugar blocks. However, the quality of the produced sugar remains low due to traditional processing methods, resulting in a relatively short shelf life and limited market value. Additionally, the lack of knowledge regarding product diversification has prevented the community from optimizing the potential of derivative products such as palm sugar granules (gula semut). Through the KKN-T program, an initial observation was conducted to identify issues found in the village’s production process, followed by a technical trial of granulated palm sugar processing using a crystallization machine, a drying oven, and a grinding machine. The results demonstrated that the application of appropriate technology significantly improves product quality, particularly in terms of texture, moisture content, and product stability. A socialization session was conducted to inform the community that palm sugar blocks can be converted into granulated palm sugar through reheating, crystallization, and drying processes. The introduction of this technology enhanced the community’s understanding of product diversification and broader market opportunities. Positive responses from participants indicated that the activity effectively addressed previously encountered issues and increased motivation among artisans to develop higher-value palm sugar products. Thus, the socialization and demonstration activities serve as an initial step toward enabling the Giri Madia community to optimize palm-based products as a competitive and sustainable local commodity.

Abstract

Giri Madia Village, Lingsar District, West Lombok Regency, has the potential for non-timber forest products in the form of sugar palm, which is managed by the Giri Madia Forest Farmers Group (KTH) under the Community Forestry (HKm) scheme. Although processed sugar palm products such as palm sugar, palm sugar, liquid palm sugar, and other derivative products have high economic value, their development still faces limitations in the marketing aspect. This community service activity aims to strengthen market access for sugar palm products through event-based marketing assistance. The implementation method is carried out in stages, including preparation, implementation, and evaluation stages. Marketing assistance is carried out through participation in several public events, namely Car Free Day (CFD) on Jalan Udayana, the opening bazaar of the 126th TNI Manunggal Membangun Desa (TMMD) at Dasan Griya, and Sunday Morning activities at the West Lombok Regent's office area. The results of the activities show that event-based marketing is able to increase product visibility, expand consumer reach, and increase the capacity and confidence of KTH members in marketing sugar palm products. In addition, the diversification of processed sugar palm products also increases the product's appeal in the market. This activity is expected to become a sustainable marketing strategy to support the economic empowerment of the Giri Madia Village community based on local potential.
