Abstract

Sampai saat ini jumlah pengguna tungku kayu bakar tradisional masih tetap tinggi untuk keperluan sehari-hari disektor rumah tangga dan UMKM. Salah satunya terdapat pada MITRA pengrajin kuliner khas Gorontalo seperti dodol di desa Reksonegoro. Oleh itu Penerapan kompor biomassa ini sangat efektif digunakan mengingat ketersediaan bakar yang melimpah. Berdasarkan observasi lapangan kendala utama yang dihadapi UMKM dodol Matuari adalah Tungku perapian yang masih sederhana seperti menggunakan tiga buah batu memasak dodol. Keadaan ini dinilai kurang efektif dalam meningkatkan kapasitas produksi. Kegiatan Pengabdian ini bertujuan untuk memberikan sentuhan teknologi tepat guna melalui penerapan kompor biomasa atau Tungku Sehat Hemat (TSHE). Disamping itu pada kegiatan pengabdian ini juga dilakukan pendampingan cara mengolah dodol cara pengolahan pangan olahan yang baik (CPPOB) dan Sanitation Standard Operating Procedures (SSOP). Berdasarkan kegiatan Pengabdian diperoleh beberapa hasil yaitu Fabrikasi Kompor biomasa yang memiliki dimensi 49 cm dan bobot sekitar 50 kg dengan hasil Uji coba perpaian bahan baku dodol sebanyak 4 Kg dimana efisiensi waktu lebih singkat sebesar 28.5% dibandingan dengan metode konvensional. Sedangkan kebutuhan bahan bakar dalam pengujian lebih hemat sebesar 35% dari seperti biasanya. Selain itu diperoleh desain kemasan dodol yang informatif memiliki ukuran 10 x 15 x 7 cm (PXLXT) untuk kapasitas 5 pcs dodol. Kedepan kegiatan pengabdian ini khususnya penerapan teknologi kompor TSHE perlu dikembangkan pada UMKM yang lain agar diperoleh Fabrikasi TSHE yang fix Desain agar dapat di produksi secara masal.

Abstract

The hybrid boiler simulator is a simulation machine designed with two working functions, namely as a medical waste processing function and as a drying cabinet function. As a medical waste processor, this machine will focus on plastic medical waste, and as a dryer function, this machine will be a clothes-drying tool or cabinet. So based on the multifunctionality of the machine, this system has hybrid working characteristics. Hybrid boiler simulators can be a solution, providing the function of processing plastic medical waste and providing the advantageous function of economical and environmentally friendly drying. Therefore, this research aims to create a hybrid boiler simulator that can be used as a plastic medical waste processing machine and also as a clothes drying machine. The hybrid boiler system is designed by applying the concept of appropriate technology so that its implementation can be done easily and practically. The research implementation method is a classification of plastic medical waste, concept design, and analysis, construction design of a hybrid boiler system combined with an incinerator for burning medical waste, system function testing, and observation of test data. The focus of his research is the heat of burning plastic waste, heat radiation, circulators, and flow control systems as well as the characteristics of the results of burning plastic waste. The results of this research are that the hybrid boiler simulator machine can function as an incinerator machine to burn plastic medical waste and function as a clothes dryer; The function of the incinerator in this machine is only through two processes, namely the process of burning plastic medical waste raw materials and the process of burning carbon gas or smoke produced from the process of burning raw materials; the sumulator machine is not yet equipped with a fogging process for the function of smoke cleaning filter and fogging control; the hybrid boiler simulator machine works on the principle of automatic control based on temperature detection using a temperature sensor; The combustion temperature in the boiler machine can be controlled at a standard of 830 °C and the drying room temperature can be set at a room temperature of 50 – 150 °C.

Abstract

Mangrove ecosystems provide essential coastal protection, nursery habitat for fisheries, and blue-carbon services; however, many Indonesian coastal areas continue to experience degradation due to land conversion, pollution, and limited monitoring capacity. This article develops a technology-oriented, marine–fisheries governance approach for mangrove rehabilitation by integrating multi-source observation and decision support. The proposed framework combines multi-temporal satellite analysis (e.g., NDVI/NDWI and mangrove-specific vegetation indices), UAV shoreline mapping, and low-power Internet of Things (IoT) sensing to capture both spatial and in situ dynamics of habitat quality. IoT nodes are configured to continuously record salinity, temperature, turbidity, dissolved oxygen, and water level as operational indicators for fisheries-relevant ecosystem conditions, while remote sensing quantifies canopy cover recovery, fragmentation, and coastline change. A data pipeline is designed for near-real-time ingestion, quality control, and anomaly detection to enable early warnings and support evidence-based enforcement. To translate measurements into management actions, the study introduces measurable performance indicators aligned with rehabilitation targets, including seedling survival, canopy recovery rate, shoreline stabilization, and compliance with water-quality thresholds, complemented by community participation and institutional coordination metrics. Scenario analysis demonstrates that the integrated approach improves prioritization of restoration zones, reduces uncertainty compared with single-source assessments, and strengthens monitoring, reporting, and verification (MRV) for blue-carbon initiatives. The framework offers a scalable model for adaptive coastal management that connects ecological monitoring, fisheries sustainability, and governance accountability.

Abstract

Mangrove ecotourism is increasingly promoted as a pathway to reconcile conservation, livelihood diversification, and coastal resilience, yet destination growth often outpaces ecological thresholds, institutional capacity, and community readiness. Building on the literature review in the International Journals and incorporating recent studies compiled in Journals, this article presents an updated integrative review on the role of carrying capacity in sustainable mangrove ecotourism, with strategic implications for Tomini Bay, Indonesia. Using only the uploaded extraction sources, the review synthesizes advances in ecological suitability assessment, physical-real-effective carrying capacity, community participation, governance arrangements, social feasibility, and tourism management innovation across Indonesia and comparable settings. The synthesis shows that carrying capacity should not be treated merely as a visitor quota; it functions as a multidimensional governance instrument linking ecosystem integrity, visitor experience, local welfare, infrastructure limits, and enforcement capacity. Recent studies also reveal a persistent gap between technical suitability analysis and day-to-day management, especially in zoning, monitoring, promotion, digital visitor control, and benefit sharing. For Tomini Bay, the review proposes a conservation-first, community-based, and adaptive-capacity model that combines spatial zoning, phased visitor limits, ecosystem monitoring, participatory governance, and blue-economy livelihood integration. The article contributes a comparative evidence base, a strategic framework, and a research agenda for emerging mangrove destinations.

Abstract

Post-harvest drying remains a critical point in the agricultural commodity value chain as it determines the rate of moisture loss, physical-chemical quality, microbiological stability, energy consumption, and environmental emissions. In the last decade, the direction of technology development has shifted from passive solar dryers to hybrid drying systems that combine greenhouses, solar collectors, thermal energy storage, auxiliary heat sources, and Internet of Things (IoT)-based monitoring and control. This review article reorganizes and updates the literature on IoT-based hybrid drying systems, focusing on five key dimensions: system architecture, heat storage media, intelligent monitoring and control, drying performance and kinetics, and economic and environmental implications. The synthesis shows that hybrid configurations consistently increase drying chamber temperature, improve heat distribution uniformity, shorten drying time, and maintain product quality compared to open drying or non-hybrid systems. The integration of sensible, latent, or a combination of both has been shown to extend the drying period during periods of decreased solar radiation and stabilize the thermal conditions of the process. At the same time, IoT enables real-time monitoring of temperature, relative humidity, airflow velocity, and equipment safety status, opening the door to more adaptive predictive control. From a sustainability perspective, recent literature shows that hybrid systems can reduce conventional energy consumption, improve exergy indicators, and deliver economic benefits through operational cost savings and potential reductions in carbon emissions. This review emphasizes that future research agendas must move beyond simply increasing drying temperatures to multi-objective optimization that integrates product quality, energy efficiency, control reliability, and environmental impact.
