In transformers installed and used in electric power systems, especially at substations (GI) there are often disturbances or problems. One of the problems with the transformer can occur due to the failure of the insulating oil which can be caused by a decrease in the value of the translucent voltage, therefore it is necessary to carry out maintenance to prevent and localize interference. Tap Changer oil is different from oil in the main tank (in terms of placement), in terms of type and function Tap Changer oil with oil in the main tank has similarities from the type of oil and its function as insulation, cooling and protecting windings from oxidation. With the method of observation (observation) in the field of all equipment worked on and with the literature method can be known the process of replacing oil On Load Tap Changer. From the results of the oil translucent voltage test study, it is known that the value of the penetrating voltage of the On Load Tap Changer oil sample used in the transformer is an average value of 38.8 kV, it can be known that the value of the new oil penetrating voltage (sample 1) being filtered is 86.8 kV, the value of the new oil penetrating voltage (sample 2) being filtered is worth 88 kV, and the value of the new oil penetrating voltage (sample 3) being filtered is 98.2 kV.

A healthy and well-maintained environment is a shared responsibility. However, problems often occur in the environment because many people do not care. Especially in the upstream part of the river which is always used as a place for laying the results of river backfill every year. Another problem is the narrow area due to the dense population of the area. Narrow land occurs everywhere, not familiar with urban areas or semi-urban villages. In carrying out community service activities, the service team uses the following activity methods: 1. Observation 2. Project planning 3. Evaluation and sharing. In connection with the problem of narrow land, the actions of the branch management and the community around Aisiyah Sukodono Kindergarten affected the success of reforestation carried out by the KKN team. All forms of involvement, efforts, and roles starting from design, implementation and maintenance are real actions in making the surrounding environment more productive. In establishing self-reliance, it is necessary to cooperate with the branch management and the local village government to develop a productive yard culture on limited land. It is hoped that this reforestation can be done by planting plants and plants that support the basic ingredients of the surrounding community.

Children with disabilities are part of diversity, but there are problems such as the lack of character formation of children, not yet optimal in developing the potential and limited skills and independence of children with disabilities. So the PKM-PM team at Slamet Riyadi University Surakarta provided a mentoring activity through the application of the aquaponics system in order to empower children with disabilities in improving the life skills of children with disabilities at YPAC Professor Doctor Soeharso Surakarta. The methods applied in this service include: (1) providing counseling and socialization related to the aquaponics system, (2) aquaponics assembly, (3) training related to aquaponics seeding and care, and (4) monitoring the development of aquaponics. The result of this service is that children with disabilities who become participants during the service process have gained knowledge related to the aquaponics system. Children routinely carry out maintenance such as spraying hydroponic vegetables, feeding catfish to cleaning fish waste at the bottom of the pond. Assistance is carried out to train the independence and responsibility of children with disabilities in aquaponic care as well as become vocational skills for them which if aquaponics continues to be developed it will become a source of income for children with disabilities, especially those living in dormitories. This service has achieved the expected results and the sustainability of this program continues to be carried out with a monitoring pattern.

PT. AIC uses a manual system in engine maintenance management. This makes it difficult to access in measuring the rate of damage, for acceleration information in maintenance management. This problem requires an identification to provide an effective machine maintenance management information system. The MTBF value will be able to detect machine damage, especially the piccanol gamma loom machine. The MTBF value can see the damage to the machine by looking at the condition of the machine, the data history of machine damage, the number of machine failures that occurred in a certain period. The MTBF value of the machine can control the reliability and know the life of the machine. Action maintenance can be done before the machine is damaged. After calculating the MTBF value of the piccanol gamma loom machine, it is still relatively small so the machine is still often damaged.

Public service or community service is defined as the provision of services to people who have an interest. The Center for Conservation and Natural Resources is an agency that is engaged in the field of conservation and natural resources which is responsible for supervising the captive efforts and maintenance of protected plants and animals by individuals, companies and institutions. The community is the main source of information for this agency in terms of monitoring the use of natural resources in their environment, but it is the community themselves who rarely provide information because the community must report directly and it takes time and money to report. One alternative that can be done to provide good service is to build an information system application for communication media with the Work System Framework approach. Work System Framework is a system where humans or machines participate in running business processes using information, technology and resources, in conducting analysis and design modeling is carried out with the Unified modeling language. Pelayanan publik atau layanan masyarakat diartikan sebagai pemberian layanan kepada  masyarakat yang mempunyai kepentingan. Balai Konservasi Dan Sumber Daya Alam adalah sebuah Instansi yang bergelut di bidang konservasi dan sumber daya alam yang bertanggung jawab mengawasi upaya-upaya penangkaran dan pemeliharaan tumbuhan dan satwa dilindungi oleh perorangan, perusahaan dan lembaga. Masyarakat merupakan sumber informasi utama bagi instansi ini dalam hal pemantauan terhadap pemanfaatan sumberdaya alam di lingkugannya, tetapi justru masyarakat sendiri yang jarang memberikan informasi dikaranakan masyarakat harus melakukan pelaporan secara langsung dan membutuhkan waktu dan biaya untuk melakukan pelaporan. Salah satu alternatif yang dapat dilakukan untuk memberikan pelayanan yang baik adalah dengan membagun aplikasi sistem informasi untuk media komunikasi dengan pendekatan Work System Framework. Work System Framework adalah sebuah sistem dimana manusia atau mesin berpartisipasi menjalankan proses bisnis dengan menggunakan informasi, teknologi dan sumber daya, dalam melakukan analisa dan perancangan dilakukan kan pemodelan dengan Unified modeling language.

Quality control is one of the obstacles experienced by PT. Wahana Kasih Mulia on CV. KKN. Quality control is an important thing that must be done by companies to minimize defective products. To be able to analyze product defects, researchers use the six sigma model, by formulating the Define, Measure, Analyze, Improve, Control (DMAIC) stages. The purpose of this study was to determine the level of quality control using the DMAIC method with the Six Sigma model applied to manufacturing companies. The results showed that from the measurement of the number of Omiland brand baby mattress products in the January-October 2021 period, it was found that defective products came from three main causes of disability. The distribution data of the number of product quality characteristics and company performance are at the sigma level of 3.50 with a DPMO value of 27,082.275. This shows that the company has not been able to meet process quality standards. Based on this research, the recommendations for improvement given are that the company needs to provide periodic training to employees, perform maintenance on machines, apply a clearer and more detailed Standard Operating Procedure (SOP), conduct tighter supervision of newly arrived raw materials and the company needs to place quality control at every stage of the production process.
