Abstract

The purpose of this study is as a source of information to study the potential of tidal energy at the estuary of the Maro River in the waters of Merauke Regency. This study uses a quantitative method, while the method for determining the location of the study used is the purposive sampling method where the data collection point is right at the end of the estuary of the Maro River because it faces directly onto the Arafura Sea. Tide data for 5 months, namely September 1, 2023 to January 31, 2024 with a pool area of 1,260,000 m2, with the consideration that from September to January there is a change of seasons that can significantly affect the tidal pattern. The tides are measured in two periods, namely the first tidal period starting at 01.00 AM to 12.00 AM and the second tidal period occurs at 01.00 PM to 12.00 PM. From the research data, it was obtained that the highest tides were in January 2024, namely the first-period tidal height difference of 5.333 meters and the energy produced was 5.292 kWh, and the second-period tidal height difference was 5.383 meters the energy produced was 5.349 kWh. The results of this study can encourage diversification of energy sources in Merauke and increase regional energy security as well as provide the data needed for further research and development of renewable energy technology, which can accelerate innovation of new technologies in the Merauke Papua region.

Abstract

This study evaluates the drying performance and energy efficiency of a solar-powered rice cabinet dryer equipped with two distinct airflow mechanisms: free convection (chimney-assisted) and forced convection (fan-assisted). Field experiments were conducted under tropical conditions in This study evaluates the drying performance and energy efficiency of a solar-powered rice cabinet dryer equipped with two distinct airflow mechanisms: free convection (chimney-assisted) and forced convection (fan-assisted). Field experiments were conducted under tropical conditions in Merauke, Indonesia, comparing drying efficiency, moisture reduction, and air mass flow across three rice grain loads: 1 kg, 3 kg, and 5 kg. The experimental design incorporated both thermal analysis and statistical evaluation (ANOVA and t-tests) to assess the effects of airflow method and grain weight on drying outcomes. Results indicate that the chimney system demonstrated more stable and efficient performance at lower grain weights (1–3 kg), with range efficiency of 32.07% - 37.5% compared to 28.26% - 32.67% using the fan-assisted method. Drying efficiency increases with grain load, reaching a maximum of 43.75% for chimney-assisted drying and 43.44% for fan-assisted drying at 5 kg. However, the fan-assisted system provided superior performance at higher loads due to improved heat and moisture transfer. Although the fan method yielded faster drying rates and more effective moisture reduction, it exhibited slightly greater variability. Despite limitations related to experimental scale and real-time solar radiation monitoring, the findings confirm that solar-powered cabinet dryers—especially those with adaptive airflow control—offer a cost-effective, energy-efficient, and scalable drying solution for smallholder rice producers. Future work should prioritize scaling up capacity, integrating hybrid energy sources, and automating temperature regulation to enhance system performance under fluctuating weather conditions
