This community service activity is carried out by identifying and inventorying problems with sub-district officials, discussing alternative solutions to problem-solving until the solution is selected, and then making pre-designed drawings, which are then carried out by presenting the results and submitting planning documents. After the pre-design drawings have been discussed and mutually agreed upon, a final renovation design and the required budget plan are created. The results of this Community Service are a Renovation Planning Document for the Petompon Sub-district Hall, which will guide government institutions in building and developing the building.

Resort Hotel and Floating Cottage, is one of the tourist attractions that many people visit for vacation. The planning of the Resort Hotel and Floating Cottage utilizes the natural beauty in the form of lake and mountain views located in Cigombong District, Bogor Regency and the location is a Kawasan Ekonomi Khusus (KEK) so that the Public-Private-Community Partnership, operational model is applied, namely a partnership between the government, entrepreneurs, and the community. Tourism in Indonesia has an important role in driving national economic growth and improving people's welfare. The natural beauty spread across Indonesia has the potential for tourism development, especially for Resort Hotels and Floating Cottages. In its realization, there are facilities related to local culture so that the community can contribute. This Resort Hotel and Floating Cottage planning is classified as a 3-star Health Resort & Spa type with more complete facilities. In addition, because the planning of this Resort building utilizes the beauty of nature, the Biophilic Architecture approach was chosen which basically has the principle of building a good relationship between humans, nature, and buildings. 

Globalization becomes inevitable for almost all aspects of life, especially in the industrial sector. Globalization has brought the industry to experience a structural transformation that focuses on technology. The structural transformation experienced by the industrial sector may have positive and negative effects, not only for the industry itself, but for the surrounding communities and the environment. The research method used in this research is initiative descriptive qualitatively by writing observation written, with data in the form of field notes. Technological advances are tested on the areas of the industry, is; Production, Research and Development / Research and Development (R & D), operational management, logistics and supply chain management, finance and accounting, human resources (HR), marketing and sales, information technology (IT), laws and compliance, and customer service

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
