Abstract

Water is a basic human need that must be fulfilled. The need for clean water is increasing while the availability of clean water is limited, so researchers are trying to use sea water as raw material for fresh water. Sea water is an abundant source of water but still contains salt, therefore it is necessary to separate sea water and its salt content to produce fresh water or desalination, one way is to use solar stil. Solar stills are mostly used for desalination processes on the coast and remote area because they can be operated easily and can be manufactured at low cost. However, solar still has low productivity, so various studies have been carried out to increase desalination yields, such as the addition of a condenser. Aim of this study was to determine the thermal efficiency and effectiveness of the condenser on solar stills. The research was conducted in period March - May 2021. The materials used are aluminum with a length of 300 mm, a width of 300 mm and a thickness of 1.6 mm for the basin plate, double glass with a thickness of 3 mm for the top and sides of the solar still. The study was conducted indoor with radiation intensity using halogen lamps. The variables measured were water temperature, evaporation, inner glass surface, condenser, inlet and outlet of the condenser cooler using a fluke meter, radiation intensity using a solar power meter and desalinated water using a digital balance. From the results of the study, the average thermal efficiency of the condenser in the integrated solar still reached 83.94% and the desalination mass of seawater reached 451.32 grams with the effectiveness of condenser production of 96.4% and the correlation value of 0.99.

Abstract

Waterwheel is a component in a Micro Hydro Power Plant (PLTMH) which obtains energy from flowing water which has a height and speed. The amount of energy converted by the water wheel depends on the shape of the blade and the installation position, but the losses due to wasted water are still large. Therefore this study proposes a closed water wheel to reduce losses. This research uses two condition fo water wheel: open wheel and closed wheel. This research uses one mill which applied into two conditions. The waterwheel is made using Polylactid Acid (PLA)and tested using 2 inch pipe lines and flow rates of 10, 12, 14, 16, 18, 20 m3/hour. The efficiency of a closed water wheel is higher than that of an open wheel at all discharge rates. The highest efficiency for a closed wheel is 54.54% and for an open wheel is 52.25% at a discharge of 10 m3/hour with a loss ratio of 0.078 for an open wheel and 0.065 for a closed wheel which shows that the losses in the water wheel are reduced.

Abstract

Planting mangrove trees on Pari Island, Jakarta, is an effective solution to address coastal ecosystem degradation and loss of biodiversity. This research aims to explain the method of mangrove tree planting involving the participation of local communities and analyze its impact on coastal ecosystems and community well-being. Through problem identification, goal formulation, research design, data collection, data analysis, and interpretation of results, significant scientific findings are obtained. The first scientific finding is an increase in biodiversity after mangrove tree planting. The research shows that planting mangrove trees provides an ideal habitat for various organisms, including fish, mollusks, and birds, thereby increasing the number of species inhabiting the mangrove ecosystem. The second scientific finding is an improvement in water quality around the mangrove planting area. Mangroves have the ability to absorb nutrients and reduce pollution levels in the water. Therefore, after planting, there is a decrease in the levels of pollutants such as heavy metals and nutrients in the surrounding waters. This study also found that mangrove ecosystems play a role in natural disaster mitigation. Planting mangrove trees reduces coastal erosion because the complex and robust root systems of mangroves help maintain soil stability. Comparisons with previous research support these scientific findings, indicating that planting mangrove trees effectively enhances biodiversity, improves water quality, and reduces coastal erosion.

Abstract

Sumber energi terbarukan yang berkaitan dengan sumberdaya hayati berasal dari biomassa. Biomassa merupakan bahan baku dalam produk bioenergi. Energi yang dihasilkan berbentuk gas disebut sebagai biogas. Dalam pembuatan biogas terjadi konversi energi biomassa melalui proses biokimia yang menghasilkan energi panas dan energi listrik. Bahan biogas diperoleh dari limbah pertanian, limbah peternakan, limbah kehutanan, limbah tanaman, dan limbah organik. Oleh karena itu potensi biogas sangat besar, karena limbah tumbuhan dan limbah hewan sebagai bahan baku melimpah. Limbah hewan yang digunakan untuk membuat biogas berupa kotoran hewan ternak yang salah satu contohnya adalah kotoran kambing. Kambing diternak dan dipelihara untuk dijadikan sebagai hewan akikah dan hewan kurban. Sebagai hewan untuk akikah kambing dipelihara dalam kandang. Jumlah kandang lebih dari satu memerlukan bangunan posko. Bangunan-bangunan sederhana tersebut yang hampir semua materialnya terdiri dari kayu tetap memerlukan energi untuk dapat ditempati. Kebutuhan energi untuk penerangan kandang dan posko tidak dapat dihindari. Selama ini energi listrik dipasok dari rumah sebelah, sedangkan kotoran kambing tidak dimanfaatkan. Kotoran tersebut dikumpulkan dan dikeringkan kemudian dibuang atau dibiarkan begitu saja. Sebagian ada yang memintanya untuk pupuk tanaman. Dengan demikian tampak bahwa ada permasalahan pada pengelolaan ternak kambing untuk keperluan akikah dan kurban yang berkaitan dengan efisiensi penggunaan energi dan pengelolaan limbah. Kotoran kambing harus dikelola dengan menjadikannya sebagai bahan baku biogas. Biogas dapat menghasilkan energi listrik untuk penerangan dan energi panas untuk memasak. Biogas diperoleh dari kotoran kambing yang dimasukan ke dalam reaktor/digester. Gas ini dihasilkan dari proses penguraian bahan organik oleh mikroorganisme dalam keadaan anaerob. Dalam digester yang kedap udara itu terjadi proses dekomposisi bahan organik tersebut. Melalui pemanfaatan kotoran kambing diharapkan terjadi penghematan dalam penggunaan energi listrik, sehingga dapat menekan biaya pemakaian listrik.

Abstract

Water has become a vital necessity for every living organism to survive, leading to a threefold increase in global freshwater usage over the past 50 years. However, only 2.8% of the Earth's surface water is freshwater, while the rest is seawater. Therefore, seawater is processed into clean freshwater through desalination methods to make it consumable for the public. The desalination process involves two stages: evaporation and condensation aided by heat energy from a heater plate and a vacuum system. The use of vacuum in the desalination device aims to accelerate evaporation. In this study, three vacuum pressure variables were tested, namely no vacuum, 1 inHg vacuum pressure, and 2 inHg vacuum pressure. Data will be collected every 5 minutes for a total duration of 30 minutes for each variable. The research findings indicate that desalination using a vacuum system significantly affects the evaporation rate and the amount of freshwater obtained from the condensation process.

Abstract

This research aims to analyze and model wheel-based floating energy generation technology. The current energy crisis requires us to look for sustainable solutions to meet energy needs. The Indonesian government has targeted renewable energy use of 23% by 2025, especially in remote areas. One solution to overcome this challenge is energy storage technology. Energy storage using floating technology is an innovative solution that is being developed. In this research, we analyze the design of a floating energy wheel with a capacity of 110 kW as an alternative source of electrical energy. Wheel energy is produced from a combination of buoyancy energy and energy originating from the weight of water which is produced by the difference in fluid density in the water and air environments. The research results show that this floating energy wheel can produce a torque of 7710,62 Nm and a power of 113,83 kW, showing great potential in renewable energy storage applications. Wheel-based floating energy generation technology has the potential to be an innovative solution in renewable energy storage. Further research needs to be carried out on a larger scale and field tests to validate the potential and efficiency of this technology in the real world
