Abstract

Mini Hydro Power Plant (PLTM) is a small-scale power plant using hydropower that utilizes the height of the waterfall (head) and the amount of water discharge. Because using water as the primary source, the power produced is irregular due to weather factors, it is necessary to conduct an Analysis to determine the potential energy that Taluda''a waterfall is at peak load. The research was conducted at Taluda'a waterfall, Bone District, Bone Bolango Regency, 65 km from downtown Gorontalo. The type of research used includes descriptive analysis; data sources are data obtained from several existing literature and research results, both experimental research results and survey research or directly in the field related to this research. The development of the analysis of the discharge on the Carrier channel (Headrace) is 8.83 m³ / s, and the water discharge on the rapid pipe (Penstok) is 5.1 m³ / s With a shot of 5.1 m³ / s and a head of 20 meters can generate hydro power of 999.6 kW. The actual charge dramatically affects the amount of energy generated. The Taluda'a PLTM has a 20-meter high head which is relatively low for a discharge of 5.1 m³/s. If the actual charge of the taluda'a PLTM is 40 meters high, the power that can be generated reaches 1.9 MW.

Abstract

The Mini Hydro Power Plant (PLTM) is an electricity facility located in Ilohuuwa Village, Bone District, Bone Bolango Regency, Gorontalo Province, using the irrigation channels of the Taludaa River and the Iya River. In the working area of ​​PT. PLN (Persero) Sultenggo Region, Gorontalo Branch. PLTM Taludaa Unit I always plans its operating system to obtain maximum electricity production according to targets every year. However, every generator will generally experience many problems with airflow and components that hinder the process of using electrical energy so that it can grow. The analysis results show that the transmission used is a shaft that is 3M long, and the post weighs 83 kg. The shaft is the transmission link from the turbine to the generator. Then, with the flywheel, it is just balancing the rotation or (Balancing) with a flywheel weight of 76 kg and the moment of inertia that is considered. It is 121.60kg/m2. Then, with the bearing resistance, the bearing life has been calculated based on the load and rotation speed. The greater the load and rotation speed, the smaller the bearing life. The results obtained are 14.5457 working hours, 6060 per day, 119 per month, and 16.6 per year, so it defines the bearing life as being able to last 16.6 years. The turbine efficiency result is 0.94, calculated using the data specifications in the Taluda'a PLTM or (MANUAL BOOK). Then, the results obtained by KW every day depend on the air flow entering the turbine. Calculated using specifications, it can produce 991.2 Kw per 1 unit. Meanwhile, the Taluda'a PLTM uses two teams, so the Kwh made is 991.2 Kw x2, calculated using the Taluda'a PLTM specification data. Evaluation of the average net capacity from 2022 to 2023 experiences an increase and decrease in Kwh produced due to the rainy and dry seasons.

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.
