Abstract

Electrical energy crisis related to the increasing population in an area will increase the electrical energy customers. Besides diminishing reserves of fossil energy that is required of alternative energy from renewable energy sources. The problem is in incorporating a potential source of renewable energy with a generator needs power generation hybrid, the hybrid system with a generator as backup energy utilization is less than optimal because when there was a deficit power generator takes over all of the power wasted in renewable energy generation. The purpose of study is to produce a hybrid system design between the generation of solar energy, wind energy and generator as support (support) when the power deficit in energy of renewable generator. Research Method in the design of hybrid system is a design block diagram consisting of solar panels, wind turbines, inverters, and generator. At this stage it has produced research outputs in the form of models of hybrid renewable energy generation systems and generators, then make a circuit simulation and measurement. The results of this research is a hybrid system that works adaptive- connected the generator to the system when the power deficit or increase the load to provide power support on renewable energy generation. This hybrid system with a capacity of 3.5 kW less power than the previous system with the composition generator 5.7 kW 2.2 kW of renewable energy consists of a 1 kW solar panels, wind turbines 1.3 kW and 1.3 kW generator voltage at 310V DC bus coupling, the voltage on the bus coupling AC 220V / 50 Hz, total load current at 16A. The percentage utilization of renewable energy rose from 11.73% to 24,94% and generator utilization fell from 24.50% to 16.74%.

Abstract

Polycyclic Aromatic Hydrocarbons (PAHs) have the potential to contaminate the coastal area of Plawangan Timur, Cilacap, Indonesia. Therefore, this research aims to determine the composition, distribution, source, and contamination level of PAHs in this region. Sediment samples were taken at seven stations. The research findings indicate that among the 16 types of PAHs, the proportion of each PAH varied between 3-12%. Notably, Benzo(a) Pyrene (BaP) had the highest proportion at 12%, while Naphthalene had the lowest proportion at 3%. According to the distribution pattern, PAHs with a high molecular weight (HMW) are more prevalent than those with a low molecular weight (LMW). The total amount of PAHs ranged from 185 to 1289.9 mg.kg-1 (dw), with an average of 1016.97 mg.kg-1 (dw). Using a diagnostic ratio, it was determined that the origin of the PAHs was either petrogenic, pyrogenic, mixed petrogenic and pyrogenic, or pyrolytic. As a result, Plawangan Timur's degree of pollution was classified as a very high polluted. The average concentration value of each PAHs is higher than the values for the Effect Range Low (ERL) and Effect Range Median (ERM) ranges, indicated there is a significant ecological risk that could have negative consequences on marine life and the ecosystem. It is urgently to handle PAHs pollution due to their relatively high content in sediments. This can be achieved by improving the management of wastewater treatment plants (WWTPs) for industry, optimizing the role of mangrove forests in reducing pollution in the waters, as well as building and increasing collaboration between related agencies in the prevention of marine oil spills.

Abstract

Muara Kali Ijo is the place where rivers flow in Kebumen Regency, which carry a lot of domestic wastes resulting from sanitation activities, namely detergent. The study aims to determine the quality of Muara Kali Ijo Waters based on MBAS concentration (Methylen Blue Active Substances). MBAS is a standard method for determining the concentration of anionic surfactants in detergents. This study uses descriptive methods with purposive random sampling techniques. Sampling was carried out on March 11, 2023 with a total of five stations. The results of the analysis of the MBAS concentration in the BBSPJPPI laboratory ranged from 0.031 – 0.064 mg/L and the measurement of water quality parameters was still relatively good, below the quality standard threshold. PCA results show that there is a negative correlation between MBAS concentration and water quality parameters. Productive anthropogenic activities around the area have a potential to contribute detergent waste from washing activities and increase MBAS concentrations.

Abstract

Marine debris is a solid material that is intentionally or unintentionally left in the waters and can directly threaten the condition and productivity of water areas. Tirta Ayu Beach and Balongan Beach are tourist destinations that are threatened by marine debris. The presence of tourists on the beach is very beneficial for increasing regional and community income, but it can also result in an increase in the generation of waste generated so that a lot of this waste accumulates and is distributed to various places and has a negative impact on the waters. This study aims to determine the species composition, weight, density, and distribution of marine debris at Tirta Ayu Beach and Balongan Beach. Sampling was conducted at 8 research stations, then classified and analyzed based on UNEP and KLHK provisions. The results showed that the types of marine debris found on Tirta Ayu Beach and Balongan Beach included plastic, plastic foam, rubber, paper and cardboard, wood, glass, cloth, and other materials. Plastic is a type of marine debris dominating Balongan Beach (89%) and Tirta Ayu Beach (81%). The highest density value of marine debris based on quantity and weight was found on Tirta Ayu Beach with a value of (5.0 ± 1.9 items/m2) and a weight of 25.8 ± 16.3 gram/m2.

Abstract

Ekosistem mangrove merupakan salah satu ekosistem pesisir yang memiliki produktivitas tinggi dan berperan penting sebagai penyedia makanan bagi berbagai organisme, termasuk ikan glodok (mudskipper). Ikan glodok hidup di area muara hingga pesisir dan sangat bergantung pada hutan mangrove sebagai habitat mencari makan. Penelitian ini bertujuan untuk mengetahui tingkat kerapatan mangrove, bioekologi ikan glodok yang meliputi pola pertumbuhan dan faktor kondisi, serta hubungan antara kerapatan mangrove dengan kelimpahan ikan glodok di Kawasan Ekosistem Esensial (KEE) Muara Kali Ijo, Kabupaten Kebumen. Metode yang digunakan adalah purposive sampling, dengan analisis data menggunakan uji korelasi dan regresi. Hasil menunjukkan bahwa kerapatan mangrove tergolong sangat padat, berkisar antara 1800–3800 pohon per hektar. Pola pertumbuhan ikan glodok bersifat allometrik negatif dengan nilai b antara 2,33–2,8. Faktor kondisi ikan berkisar antara 1,00–1,02, yang menunjukkan kondisi tubuh ikan cenderung kurus. Uji regresi menghasilkan nilai r sebesar 0,75591, menunjukkan hubungan yang kuat antara kerapatan mangrove dan kelimpahan ikan glodok. Namun, hubungan tersebut bersifat negatif, yang berarti semakin tinggi kerapatan mangrove, kelimpahan ikan glodok justru menurun.
