Kincir angin Savonius merupakan kincir poros vertikal yang sederhana, dapat bekerja dengan kecepatan angin yang rendah, mampu bekerja sendiri dan mempunyai torsi statis yang besar dibandingkan dengan jenis kincir lainnya. Penelitian ini bertujuan meningkatkan torsi statis dengan menambahkan empat plat pengarah. Pengujian dilakukan dengan variasi panjang plat pengarah (105 mm, 210 mm, 315 mm) dan jarak antara kincir dengan plat pengarah (2 mm, 4 mm, 6 mm). Pengujian dilakukan dengan komputasi dinamika fluida (CFD) pada kecepatan angin 6 m/s. Hasil yang diperoleh torsi statis maksimal didapat dari kincir dengan plat pengarah dengan panjang plat 315 mm dan jarak antara kincir dengan plat pengarah 4 mm sebesar 2,4 Nm.Kata kunci : Savonius, torsi statis, plat pengarah, komputasi dinamika fluida

The wood-furniture drying process in the industry using wood fuel is deemed inefficient, wasteful, takes a long time, is unsafe, impractical, and not environmentally friendly. Furthermore, the process of drying fertilizer blocks with the sun, apart from requiring a large area of land, also cannot be carried out in the rainy season. This service is carried out in two industrial partners, namely CV Nuansa Kayu Bekas in Sragen and PT Wira Cahya Pratama in Klaten. This service aims to increase understanding of an effective drying machine for the drying process of wood furniture and block-fertilizer in the industry by using a vapour compression cycle. In addition, to increase productivity and profits in the industry. The training venues are conducted in the industries of the two partners. Activities in this service include training on drying machines and assistance in the manufacture, operation and maintenance of effective dryers, especially for the wood-furniture and fertilizer-block industries. The implementation of the service has been going well and smoothly. The outputs produced are activity videos, publications in Suara Merdeka newspaper, Jogja Daily and the Sanata Dharma University website, service articles published in service journals, and Partner satisfaction surveys.

SMK Pangudi Luhur Leonardo Klaten is children of productive and innovative ages. So it is necessary to get additional knowledge to increase the power of innovation, especially in the face of increasing competition. Computer programming skills can increase creativity. Computer programming can help improve work efficiency, such as repetitive calculations often encountered in the design of machine elements. However, computer programming generally requires a computer or laptop, which is an obstacle for students in learning programming because they generally do not have computer or laptop facilities. In this service activity, the community service team will introduce another alternative to learning programming, namely using a cellphone (HP). Students from the two vocational schools have cellphones, but they have not been used for programming. The students are generally new to using cellphones for communication, social media or games (games). The HP has not been used as a learning tool due to ignorance, the impression that programming is complicated, and not realizing the benefits of programming itself. The service team will introduce programming using cellphones to change the paradigm so that it is hoped that students can develop programming skills independently from this service activity. It is hoped that vocational students will be more creative and develop programming skills according to their work. In addition, the output targets of this service are sending articles to community service journals uploading information on the web and social media.

One of the problems faced by middle to lower economic class people in big cities is drying clothes, both in the dry season and in the rainy season. Artificial clothes drying equipment is needed that can replace the role of solar energy. The purpose of this study was to determine the performance of electric energy clothes dryers and the length of time needed to dry clothes on a household scale. The clothes dryer works by using a heat-pump based on the vapor-compression cycle. The total power of the heat pump is 200 watt. The working fluid of the heat-pump is R134a. The working fluid used to dry clothes is air, using a closed airflow system. The research was carried out experimentally by varying the amount of clothes in the drying chamber. The clothes dryer performance (COP) of the heat pump is 7.94. Drying time for 15, 25 and 40 clothes respectively for 210 minutes, 330 minutes and 450 minutes.

The present study investigates the effect of the concentration of flexible resin on the dimensional accuracy of mixtures product manufactured by 3D printing using SLA technology. Specimens were designed and according to the ASTM D412 standard. Ten variations of resin mixtures were examined. The concentrations of the flexible resins were varied from 10% to 100%. Measurements of accuracy dimension were conducted on the fabricated specimens, and the average deviation was used to estimate the dimensional accuracy. The study reveals the least deviation in dimensions in the 10% flexible resin containing mixture and the highest in the 60% flexible resin containing mixture. The results explain the fabrication tendency of flexible resins in dimensional accuracy for 3D printing.

In the present work, a simple aeration technology, utilizing the concept of a microbubble generator (MBG), was applied to an aquaculture field. It aims to support aeration by increasing the dissolved oxygen (DO) in the water. Subsequent supporting activities were carried out, comprising design, optimization and manufacturing, installation, and trials of MBG units, followed by site exposures. During one of the exposures, two sessions covering a discussion and another practical work were conducted. The working principle of the MBG was briefly explained in the first session, while the installation and operation were practically elaborated in the second session. Additionally, two units of MBG appliances were granted to be applied on the exposure site, namely Usaha Budidaya Ikan Senandung Betta. During the following exposure, the MBG implementation was evaluated through a series of DO measurements. Here, the measurement reached a range of 5.7 – 5.9 mg/L by operating the MBG. This means that the MBG increases the DO by around 1.5 mg/L.
