ise (MSMEs). The primary issue faced by partners was temperature instability during the dough fermentation process, leading to inconsistent product quality. The implementation method included problem identification, tool design and construction, implementation at partner locations, and mentoring and evaluation. The results of the activity showed that the tool can help IoT-based systems maintain stable fermentation temperatures, improve dough quality consistency, and increase production efficiency. This initiative also has a positive impact on increasing partners' capacity to utilize appropriate technology.
Abstract:Small and Medium Industries (SMEs) play an important role in the regional and national economy, especially in providing employment and increasing the added value of local products. T.A Rezeki is one of the SMEs that produces…
uces its products by purchasing raw materials from products at chemical stores, then marketing them to surrounding areas, several restaurants, mosques and laundries directly. The design of an IoT-based batch mixer is expected to help TA Rezeki SMEs to automate the base soap stirring process so that it is more efficient and consistent. With the implementation of IoT, it is expected to reduce operational costs, increase production capacity, and produce soap products with better and uniform quality. Based on the satisfaction survey conducted, the results showed that the digitalization of soap stirring tools carried out in this activity provided benefits to SMEs by providing convenience with equipment automation and more consistent stirring so that the resulting products are also of better quality.
Abstract:Lingga Village in Karo Regency, North Sumatra, is a cultural village that preserves the traditional architecture of the Karo people, particularly the Siwaluh Jabu traditional house, which reflects the community’s life philosophy,…
philosophy, social order, and spirituality. The surrounding environment of these traditional houses remains poorly organized, with vacant land left unmanaged and declining awareness of cultural preservation, resulting in suboptimal utilization of the area’s aesthetic value, cultural function, and tourism potential. This community service program aims to arrange a cultural garden around the traditional houses while empowering the local community to manage the cultural landscape in a sustainable manner, with a focus on preserving cultural identity, improving environmental quality, and strengthening the local economy through the development of cultural tourism and agrotourism. The implementation method adopts a community-based participatory approach, carried out through several stages: site observation and mapping, focus group discussions, planning and designing the cultural garden, training and knowledge transfer, collective implementation of garden arrangement, as well as evaluation and documentation. The garden design integrates the orientation of the Siwaluh Jabu house, the cosmological meaning of space, ecological landscape principles, and the selection of local vegetation with symbolic, aesthetic, and economic value, organized into aesthetic, educational, and productive zones. The results of the program indicate the establishment of a well-arranged cultural garden rich in Karo cultural symbols, increased community capacity and participation, and the creation of a sustainable cultural landscape management model that functions as a “living laboratory” combining aesthetic, educational, economic, and spiritual roles. This model positions the community as the main actor and holds potential to be replicated in other cultural villages with similar characteristics.

Abstract:This study discusses the design and construction of a corn sheller with a capacity of 80 kg/hour using an internal combustion engine . A corn sheller is a machine that functions to shell corn to separate the corn kernels…
from the corn cobs. In Indonesia, corn is available in abundance in rural areas, especially during the harvest season. In the production process, generally, during the shelling process, many farmers still use the shelling method by hand or using simple tools, which takes quite a long time. The reason people still use the shelling method by hand or using tools is because the price of the machine is too expensive and they are not even aware of the existence of a corn shelling machine. This corn shelling machine with a 5.5 HP internal combustion engine is a tool designed to speed up and simplify the corn shelling process efficiently and produce a fairly large production capacity of 80 kg / hour. To extend the service life of this corn shelling machine, maintenance and cleanliness should be carried out so that the machine can operate optimally without problems. Safety also needs to be considered to avoid unexpected work accidents.

Medan City Employment Service. The author limits the problem only to the effect of stress and work motivation on employee performance at the Medan City Employment Agency. Formulation of the problem whether work stress and work motivation affect employee performance at the Medan City Employment Agency, the population in this study totaled 58 people as the sample. The type of this research is quantitative research, with secondary data and distributing questionnaires to respondents as a data source. The data analysis method used is multiple linear regression analysis, hypothesis testing is done by Partial Test (t), Simultaneous Test (F) and Determination Coefficient Test (R2). The results of this study are Y = 0.550 + 0.447 X1 + 0.398 X2. The stress variable has a partial effect on employee performance. This can be seen from the significant value of 0.001 <0.05 and the t-count value of 3.543 > t-table 1.673. The motivation variable has a partial effect on employee performance, this can be seen from the significant value of 0.002 <0.05 and the t-count value of 3.225 > t-table 1.673, the hypothesis is accepted. The variables of stress and work motivation simultaneously have a positive and significant effect on employee performance. This can be seen from the resulting sig value of 0.000 <0.05 and the Fcount value of 34.156 while Ftable is 3.17 so Fcount > Ftable. Based on the test results of the coefficient of determination (R2) it is known that the R square value is 0.554 which means that the influence of stress and motivation variables on performance variables is 55.4%. It means having a relationship that is not too strong. While the remaining 44.6% is caused by other factors outside the research.
