Abstract Balai Padang Adat is one of the traditional building in tropical area. The characteristic of this building is large, long and deep dimention but it has limited area of the openings. Field meassurement for 3 days and 3 times (09.00, 12.00, 15.00) is used to identify factors that affect daylighting performance. This research found that daylighting performance was in poor quality. The outdoor illumination is very high which reached 100.000 lux caused by latitude, altitude and cloud cover. The latitude is 2 o in the south from the equator's line and the altitude is 450 meters above sea level which close from the sun. The cloud cover is minimum lower than 40%. The indoor illumination can reach 1 lux as the lowest level during the day caused by obstruction, overhang, shape and space of the building, material reflectance, area and position of the openings. There is a building in the west and east and a vegetation in the south as an obstruction. This building has a large dimention with double layer room, but it has minimum material reflectance of the wall and floor. This building has a minimum area of the openings, high position of the openings near the overhangs and also long dimention of the overhang. Meassurement was done in Laras-Pematang room as a living room and Bilik room as a bedroom and kitchen. Overall, daylighting performance of this building can not meet standart activity such as illumination value, daylighting factors and daylighting distribution from morning to the evening.

The processed sea is one of the livelihood commodities in the fishing village of Surabaya. The production process includes cleaning, drying, cooking, and packaging activities. One of the problems faced is in the drying process. Dry on the highway makes the product unhygienic. Horizontal drying areas have a limited area for drying. The solution given to this problem is a multifunctional vertical drying area. Vertical drying racks can increase the quantity of drying up to 5 times. Product quality can also be improved because there is no drying on the edge of the highway which causes the product to be less hygienic. The multifunction of the drying area is obtained from 3 main functions: a drying place, a storage area, and an oven. The use of metal material aims to make the drying place have a longer life than bamboo. The use of metal angled holes is intended so that the distance between rack levels can be adjusted to the needs and can be added or reduced. The increase in the quantity and quality of production in the drying process is expected to increase the profits of the business of processed marine products in the Surabaya fishing village.

The Wiradesa activity which was held in Plunturan Village, Ponorogo Regency provided a new learning experience for students in implementing the current MBKM curriculum.  Direct learning in the field with partners to implement the knowledge that has been obtained when learning on campus, as well as new knowledge gained in the field enrich learning activities for students.  The involvement of the State Administration Study Program Wiradesa Program brought by the Student Executive Board (BEM) FISIP was held in Plunturan Village, Pulung District, Ponorogo Regency.  Where the business specifications are existing MSMEs and pioneering MSMEs that have been appointed as supporting identities for Plunturan Cultural Tourism Village.  Its activity is to develop existing and pioneering businesses.  The impact of implementing Wiradesa is not only felt by students, but also for lecturers and partners.  Therefore, through this research, the authors conducted a survey to determine the impact of the implementation of Wiradesa activities on learning in the MBKM curriculum for students, lecturers and partners which was carried out in Plunturan Village, Pulung District, Ponorogo Regency. The results of the research carried out are that there is an impact on MBKM learning through Wiradesa activities in Plunturan Village with the resulting benefits greatly impacting the economy, social and other sectors.  The impact on universities related to improving the performance of the KPI can be grouped into 3, namely the direct, ongoing and potential impacts. The direct impacts include the 2nd KPI, where students get experience outside of campus and the 7th KPI, which is a collaborative and participatory class. The ongoing impact in the 5th IKU is that the work of lecturers is used by the community. The potential impacts include the 1st KPI, which means that graduates get decent jobs and the 3rd KPI, which is lecturers who are active outside the campus.

The application of dome buildings in tourist education facilities in Simoketawang Village, Sidoarjo aims to increase educational value and attract tourists to visit the village. In this discussion, we explore the benefits and potential of applying dome structures in the context of educational tourism in Simoketawang Village. Through literature recognition, we found that the application of dome structures, such as geodesic domes, ellipsoid domes, and tropical domes, can provide architectural uniqueness and interesting experiences for visitors. Geodesic domes, with triangular segment structures, provide robustness and efficiency in construction, while ellipsoids of domes give a dynamic and aesthetic impression of modernity. The tropical dome, with its hollow and open design, prioritizes air circulation and natural lighting. In addition, the discussion also involved aspects of sustainability and community participation in the development of village tourism. The application of domes in tourist education facilities can support sustainable design principles, such as the use of natural materials and optimization of natural resources. In addition, the participation of local communities is also important in the preservation of cultural heritage and the development of ecotourism in Simoketawang Village.By combining unique architectural designs, educational values, and launches, the application of domes buildings in Simoketawang Village can provide a unique and interesting tourist experience for visitors, while supporting the development of ecotourism and the preservation of local culture.
