Abstract

The purpose of the activity is to educate the Women Farmers Group to have the knowledge and skills about galo galo honey cultivation (Trigona sp) and the establishment of a Family Medicinal Plant Garden in Nagari Tiumang, Tiumang District, Dharmasraya Regency. The implementation method for each activity is carried out in several systematic stages, namely the socialization stage, the demonstration plot stage and the mentoring stage. The results of Galo galo (Trigona sp) cultivation education activities are Women Farmers Group already has knowledge and skills on Galo galo cultivation, already has 4 Galo galo honey colonies, 2 colonies for the Trigona Itema type and 2 colonies for the Trigona Minangkabau type, where 2 colonies of the Trigona Itema type have been harvested and produce honey production as much as 250-300 grams / colony. In addition, Women Farmers Group and the community also have a 15 m x 25 m Family Medicinal Plants garden which contains 5 types of medicinal plants, such as Ginger (Zingiber officinale), Turmeric (Curcuma longa), Curcumalonga (Curcuma xanthorrhiza), Aloe vera (Aloe vera) and Betel Leaf (Piper betle). Conclusion is this service activity has gone well where the target already has a Galo galo honey (Trigona sp) business and a Toga garden, so that it will be able to realize the occurrence of independence and empowerment in the community, especially for members of Women Farmers Group orchids and the community in Nagari Tiumang, Dharmasraya Regency.

Abstract

Our research is introducing a lighting system using dimming lamps to utilize natural sunlight to save electrical energy in campus buildings. It began with designing an LED light-dimming system using AC chopper technology. It was tested in library rooms in campus buildings. Its room is divided into three zones (A, B, C) based on the intensity of natural light reaching the room and the location of the work points. We analyzed the influence of the environment around the research object, including the location of work points, weather conditions, the position of the sun, and electrical energy saving in lighting systems using dimming LED lights in campus buildings. The test results show that implementing the proposed dimming system can reduce room electricity consumption by an average of 50.31% in good weather conditions. The location of the work point in the room dramatically influences the amount of this savings. For work point locations in zone C, these savings can reach 93.707%, while for work points in zone A, the savings are only 12.177%. The results show that the percentage of electricity consumption savings from the lighting system can be increased by increasing the natural light that reaches the room.

Abstract

This research focuses on the design, development, and optimization of the electric go-kart "E-Andalasian" as an environmentally friendly campus transportation solution. Structural analysis was performed using Finite Element Analysis (FEA) to evaluate stress distribution and deformation under static and dynamic loads. The study also optimizes the BLDC motor, 72V 40Ah lithium battery, and controller to achieve efficient and reliable performance. Results indicate critical stress points at wheel joints, with recommendations for aluminum alloy use to enhance weight efficiency. Experimental testing showed that the motor achieved a maximum torque of 44.52 N.m and 6447 RPM, while the battery supports a range of 40 km with a charging time of 2 hours 9 minutes. Although the maximum speed reached 59 km/h, additional optimization is required to meet the original design target. The findings provide a prototype foundation for future improvements and contribute to green campus mobility.

Abstract

This study examines the effect of applying secondary skin with varying slope angles on the facade on energy efficiency and indoor thermal comfort. Facades with varying slope angles are designed to respond adaptively to external environmental conditions, such as solar radiation intensity, air temperature, and wind movement, with the aim of minimizing the building's thermal load and improving overall thermal performance. An experimental approach is used to evaluate the effectiveness of secondary skin with varying slopes. The thermal comfort parameters measured include air temperature, relative humidity, lighting intensity, and energy requirements for cooling, all of which are analyzed based on ASHRAE standards. The results of the study indicate that the use of facades with opening slopes of 10°, 20°, and 30° can reduce the room cooling load by 11.05%, 10.95%, and 10.80%, respectively. In addition, there was a decrease in the average Predicted Mean Vote (PMV) value of 0.059 (5.03%) at a slope of 10°, 0.073 (6.29%) at a slope of 20°, and 0.078 (7.20%) at a slope of 30°. These findings indicate that secondary skin with variations in the slope angle of the facade is an innovative and sustainable approach in passive cooling strategies, which contributes to reducing energy consumption.

Abstract

Vehicle crashworthiness is a critical aspect of automotive safety engineering designed to minimize injury to occupants during collisions. This paper investigates the role of trigger mechanisms in enhancing crashworthiness by managing energy absorption and deformation during impact. Trigger mechanisms, including structural features like grooves, holes, or geometric discontinuities, initiate controlled deformation, optimizing energy dissipation. This study evaluates the effectiveness of crash boxes with various cross sections and six trigger designs: bead initiator, diamond notch, smaller thickness, circular notch, circular holes, and oval holes, to absorb energy of collision using computational software, MSC Dytran. The results show that a crash box with an octagonal section absorbs more energy than those with square, rectangular, or hexagonal sections. Among the introduced trigger designs, the models of bead initiator, circular notches, and circular holes were considerably the most effective in energy absorption.

Abstract

The food business opportunity is very interesting for home industry entrepreneurs in West Sumatra, a home industry of cassava chips. The step of the cassava chip production process that takes longer time than the other step is the washing process. The cassava washing process is carried out manually because washing device that uses motor drives are not affordable for home industry entrepreneurs. In addition, the cassava washing process makes a physical complaint from the operators. Therefore, this research designs a cassava washer that is affordable for the home industry by considering design methods, ergonomic aspects, and customers' needs. This design is carried out using the Quality Function Deployment (QFD) method to translate the voice of the customer into technical and design characteristics, morphological charts for generating alternative designs, and an objective weighted method for evaluating that alternative. The result of this research is the design of a cassava washer which is more practical because it makes the operator works easier and can save time in the washing process. It is also very affordable, with an estimated cost of production IDR2,397,743.

Abstract

This community service program aims to address three main issues faced by the partner: production, marketing, and managerial aspects. In production, problems include poor water quality, inconsistent production, product durability in packaging, and the absence of microbiological testing. Good water quality and stable supply are essential for maintaining product quality and production efficiency. In marketing, the challenges involve unprofessional packaging, limited understanding of digital marketing, and low brand awareness. Professional packaging and digital marketing strategies can enhance product value and branding. In financial management, issues include unsystematic bookkeeping, suboptimal pricing strategies, limited understanding of cost of goods sold (COGS), lack of PIRT certification, and unregistered brand intellectual property. Proper financial recording and COGS knowledge are crucial for cash flow control and accurate pricing. The program aims to improve financial management efficiency, ensure consistent production quality, and enhance branding and digital marketing. Expected outputs include a nationally accredited journal article, intellectual property registration, media publication, and promotional video.Keywords: MSMEs; Digital Marketing; SIAPIK; Water Filter; Brand Awareness
