A vortex turbine is a turbine that operates by utilizing a vortex flow as a drive for turbine blades which then the turbine shaft is connected to a generator to convert shaft mechanical energy into the form of electrical energy. In this study a test will be carried out on a vortex turbine with a head of 1 m, a flow rate of 0.12 m3/s. In the testing process, 3 types of blades will be used, namely straight blades, curved blades and finned curved blades. After testing, it can be concluded that the highest power is found in the curved blade of 959.08 Watt and then the finned curved blade is 714.38 Watt, while the lowest power is found in the straight blade type of 582.48 Watt. The resulting rotation can be seen in the graph below. The highest rotation is found in the finned curved blade of 540.00 rpm and the next is the curved blade of 517.67 rpm, while the lowest rotation is found in the straight blade type of 510.67 rpm. For the efficiency of each metal blade, it can be seen that curved blades are still the highest followed by curved blades with finned blades, the lowest being straight blades with salty blade efficiencies of 98%, 73% and 59%

This research focuses on the effect of holes and the number of disks on the performance of the Tesla turbine, where this experiment uses one Tesla turbine unit with a constant inflow discharge of 0.037 m3/s and a constant load of 50 kg on. Then testing was carried out by varying the number of holes on the disk (4, 6, 8) and varying the number of disks (11,13, 15) with a hole diameter of 10 mm, disk diameter of 160 mm, disk thickness of 0.5 mm. After testing and data analysis, it can be seen that the variations in the number of holes on the disk (4,6,8) and the number of disks factor can be concluded that the maximum power is 310,148 Watts for the number of holes on the disk factor while for the number of disks factor it is 301,154 Watts, where there is a difference of 8,994 Watts. Meanwhile, the maximum efficiency is 73.754 for the number of holes in the disk, while for the number of disks it is 71.652, where there is a difference of 2.102.

The distribution of PLN electricity to remote areas has not been achieved so there are other alternative resources needed, for example solar power plants. The aim of this research is to design and analyze the potential for a solar power plant with an off-grid system that can be used to supply residential homes when PLN power goes out. This solar power plant is designed for a load of 17 kwh / per day, the efficiency (ηinv) of the inverter is 93%, the efficiency of the battery block is ηBAh = 85%, the DC system voltage is chosen as 48 V. The solar power generation system designed in this research is an off system -lattice. The main components were chosen based on the calculation results for the number of panels of 3563 Wp, with a total storage battery of 1172 Ah. If you use 48v/160ah Lithium batteries connected in parallel using 7 batteries with a charging time of 7.3 hours, minimum scc current of 74 Ah, inverter current of 41.6 Ah with a panel tilt angle of 15 degrees.

Dampak kehidupan sosial dan ekonomi masyarakat di lingkungan perkotaan menyebabkan kurangnya kesadaran dan kepedulian masyarakat terhadap kondisi lingkungan di sekitarnya. Kondisi lingkungan yang tidak tertata dengan baik serta tidak adanya penghijauan menjadi bukti dari kurangnya kesadaran dan kepedulian masyarakat RW 04, Kelurahan Mulyorejo terhadap lingkungan sebagai dampak kehidupan sosial ekonomi masyarakat. Tujuan dari kegiatan pengabdian tersebut adalah untuk menginisiasi terciptanya lingkungan hijau melalui konsep “Kampung Tematik Asri” bagi masyarakat RW 04, Kelurahan Mulyorejo. Metode yang digunakan dalam kegiatan penghijauan ini adalah sosialisasi dan pendampingan. Sosialisasi dilakukan untuk mengenalkan penghijauan lingkungan dengan penerapan konsep “Kampung Tematik Asri”, sedangkan pendampingan sendiri merupakan wujud atau realisasi dari konsep tersebut yang melibatkan warga RW 04 sebagai mitra dalam pelaksanaan program ini. Hasil yang diperoleh dari program pengabdian ini adalah peningkatan pemahaman masyarakat terhadap lingkungan, implementasi “Kampung Tematik Asri” dengan penanaman tanaman hias pada beberapa lokasi di jalan masuk wilayah RW dan RT setempat, dan pembuatan peta RW 04 untuk membantu penataan wilayah setempat.

The Covid-19 pandemic has significantly impacted society, causing an economic crisis. The thematic village program is a community empowerment effort based on the unique potential characteristics of local communities. This community service program aims to strengthen the concept of thematic villages through the revitalization of the Ginger Red Thematic Village in RW 07, located in Mulyorejo Village, Sukun District, Malang City. The methods applied include outreach, assistance, and improvement of urban farming facilities for red ginger cultivation. The results of this community service program show that the revitalization of the Red Ginger Thematic Village has succeeded in increasing the function of the greenhouse, supporting the urban farming program, and increasing the number of successfully cultivated red ginger plants by the local community. This program represents a significant step in supporting economic recovery and community empowerment amidst the crisis caused by the Covid-19 pandemic.

This study aims to highlight innovative and sustainable measures in adaptation to climate change and the Covid-19 pandemic through integration into flood control efforts based on empirical data in Glintung Kampong, an informal flood-prone settlement in Indonesia and to explore what local wisdom values influence the success of the measures undertaken. This study was designed to use a mixed method combining qualitative and quantitative data. Qualitative data consists of in-depth interviews, observations, and desk studies. Quantitative data is used for the generalization of some qualitative data across a wider field. The study results show that the existence of drainage channel facilities from the government can trigger creative ideas and innovative measures in the community. Community involvement with their â€œguyub rukunâ€ and â€œgotong royongâ€ values is the most influential factor in determining the success of the program, followed by community leaders, the ability to adapt to flood risk, and the ability to establish good interactions with external parties.
