Minat baca pada masyarakat Indonesia masih sangat rendah, salah satunya di desa Kesuben yang notabene masyarakatnya rata-rata pendidikannya masih rendah. Media Pembelajaran semakin berkembang seiring dengan perkembangan teknologi salah satunya dengan menggunakan Ensiklopedia pintar supaya belajar lebih interaktif. Dengan ini kami memberikan pelatihan dan pendampingan yang bertujuan untuk menambah literasi media pembelajaran yang berbasis teknologi untuk TBM (Taman Baca Masyarakat) Lentera Hati Durensawit Desa Kesuben Kecamatan Lebaksiu Kabupaten Tegal. Sebuah alat  yang di buat dengan microcontroller Arduino dan sensor RFID untuk mengenali sebuah gambar dan akan mengeluarkan suara hewan sesuai dengan yang ada digambar dengan Bahasa inggris. Proses pengenalan Ensiklopedia pintar kepada pendidik dan anak didik di TBM (Taman Baca Masyarakat) Lentera Hati Durensawit dengan memperkenalkan cara membuat hingga proses pengoperasian. Hasil PKM dengan pengenalan Ensiklopedia pintar bisa membantu dan jadi pilihan lain untuk pendidik sebagai media ajar yang diapliksiakan kepada anak didik sehingga dapat meningkatkan minat baca. Sedangkan untuk anak didik manfaat yang bisa didapat adalah mereka jadi lebih semangat belajar bahasa inggris khususnya mengalami peningkatan belajar secara signifikan

In combined cycle power plants (CCPPs), the bypass butterfly valve is a key component to facilitate regulation of exhaust gas energy available at the turbine and to not produce too much boost pressure. The conventional damper valve causes leakage, back flow into the turbine, and damage of the blade, and the existing dual-layered seal with polytetrafluoroethylene (PTFE) and metal should be frequently replaced owing to its low durability and deterioration of mechanical properties under a high temperature. This study devised a triple offset butterfly valve with a new type of seal by alternatively laminating stainless steel and graphite to improve valve performance at the high temperature (350 °C). The slope angles of the seal contact surface to prevent friction were calculated using the mathematical models of the triple offset. Thermal-structure coupled analyses by varying the number of graphite and thickness were conducted, and the seven-layer model with the graphite thickness of 0.8 mm, which shows airtightness and smooth operation, was chosen. The contact stresses behaviors of the graphite at 350 °C and at −196 °C were investigated, and it was found that the graphite is in charge of improving driving performance of the disc at the high temperature and sealing performance at the cryogenic temperature. The performance tests and the field tests of the suggested model verified its performance at the working temperature.

The waste processing and renewable energy are being the issues in the industrial 4.0 era. Kitchen and organic trash in the rural areas will become a disaster if there is no solutions. On the other hand, kitchen and organic waste have a positive side, that they can be converted into biogas which can be converted into electricity. On the Minister of Energy and Mineral Resources Regulation Number 27 of 2014, supports the development of biogas and will buy electricity from the biogas conversion. The potential for biogas that obtained by the organic trash per 1000 people is 7619.8 liters of biogas, it meas that the energy contained is still abundant and the production can still be increased if processed with a modern digester system. This research produces a tool in the form of a portable digester that named GenBIoT (IoT-based Biogas Generator) which can be used by the public to produce biogas that  used by home industries or general factories. This research used the research method that similar to System Development Life Cycle (SDLC), this tool is built with several stages starting from planning analysis, designing, functional testing, data analysis and reporting of the results or implementing this tool that can be used as an alternative, as a cheap and easy source energy. This tool is based on the Internet of Things so that this tool can be monitored regarding gas pressure in the reactor, biogas volume and it will detect if there is a biogas leak so it will displayed on the system. To produce the maximum biogas composition, 50% of cow dung is required, 40% of kitchen trash and 10% of water with a ratio of 5: 4: 1 so it will produce 40 kg of biogas with a volume of methane gas (VGM) 0.11 m3 of biogas for cow dung. and 0.04 m3. The third experiment becomes the basis of future biogas production with energy produced from biogas per day of 716.39 Wh
