The aim of the research is to design a tool that can assist coffee farmers in determining the quality of the coffee beans produced according to the desired grade value of the coffee beans. The tool is designed to be able to fulfill the functional value produced by the tool. So that farmers can work fast, save time in the process of grading and sorting coffee beans, able to minimize operational costs, and save energy. With an electric motor power of 1 hp, the sizing machine is capable of sorting coffee with a capacity of ±250 kg/hour, therefore a day's the process of sorting 500 kg of coffee can be achieved in less than 2 hours. This really helps coffee farmers in determining the quality of coffee beans without taking a long time.

ANALISIS KOMPETENSI LULUSAN SMK YANG DIBUTUHKAN DU/DI DENGAN METODE MULTIPLE CRITERIA UTILITY ASSESMENT (MCUA)

2024-03-25T07:43:07+00:00

Abstract: The purpose of this study is to determine the competency of SMK graduates with Dudi competence (Business World/Industry World). There is still a gap between the skills possessed by vocational high school graduates and the needs of the business and industry world. This is due to the mismatch between the competencies taught in education and the existing technological developments. Multiple Criteria Utility Assessment (MCUA) is a method used in decision-making that involves multiple criteria or factors that need to be evaluated. This method helps in selecting the best alternative based on objective assessments of various relevant factors. It involves collecting data on criteria relevant to decision-making and then assigning weights or importance to each criterion. Then, each alternative is evaluated based on these criteria, and a value or score is given for each alternative on each criterion. These scores are then used to calculate the utility value for each alternative. The results obtained show that Problem A, which is communication skills with a total value of 165 after being multiplied by the weight, becomes the first priority for improvement. Problem B, management skills, has a total value of 155, making it the third priority for improvement. The total value of 155 becomes the second priority for improvement. Overall, it is necessary to design an integrated and sustainable program in schools or educational institutions to enhance students' communication, planning and organizational skills, as well as their management abilities. Collaboration with industries and the implementation of active and project-based teaching methods can provide practical experiences to students. It is also important to involve experts and industry practitioners in designing programs that are relevant to the current job market needs.

PENGGUNAAN DESAIN FAÇADE GANDA KACA DI GEDUNG FAKULTAS PSIKOLOGI UNIVERSITAS DIPONEGORO BERDASARKAN PERATURAN PEMERINTAH

2024-03-14T05:57:03+00:00

Indonesia with its tropical climate should adopt green buildings arranged by the Government Regulation. The green buildings usually use the Double Skin Façade (DF) system to mitigate heat transfer into interior spaces. One of the green buildings at Diponegoro University is the Psychology Faculty. This research aims to analyze this green building based on Government Regulation, such as stipulated in SNI 6389-2011 and the Ministerial Regulation of PUPR of the Republic of Indonesia Number 21, dated 2021, which mandates that the overall heat transfer value of the outer building should not exceed 35 W/m². By applying the descriptive qualitative method, the Overall thermal Transfer Value (OTTV) was measured. The results show that Faculty of Psychology building at Diponegoro University utilizes the DSF system, with stopsol Asahimas dark blue glass as the outer skin and predominantly brick inner skin equipped with operable windows with the Overall Thermal Transfer Value (OTTV) value of 42.6 W/m². However, the comprehensive building OTTV value is 54.94 W/m², classified as non-compliant with green building design criteria based on the Government Regulations.

ROLLER SHAF; PENGGULUNG KAIN SAJADAH PANJANG BERBASIS MESIN

2024-03-21T04:17:12+00:00

The aim of this research is to make a Roller Shaf as an alternative tool for rolling long cloth based on machine technology, namely using an AC electric motor. The method used in this research uses the interactive model R&D method from Miles & Huberman which consists of four components, namely data collection, data reduction, and prototype testing on users. Respondents came from the administrators of mosques and prayer rooms in Palangka Raya who were observed randomly, including the Takmir of the Palangka Raya University Mosque, Amanah Mosque, Flamboyan Mosque, Gede Kalampangan Mosque, Al-Khaidir Badak 22 Mosque, and the Jami' Nurul Islam Mosque in Pasar Besar Palangka Raya, then analyzed using qualitative descriptive. The results obtained were that the Roller Shaf trial was carried out at the Salahuddin Campus Mosque, Palangka Raya University and showed that the Roller Shaf could be used, equipped with a volume speed as a rolling speed controller. The Roller Shaf is made from environmentally friendly materials, equipped with a machine microcontroller from an 8 Volt AC dynamo, and covered with a box that is adjusted to the size of the fabric. The obstacle with the Roller Shaf is the use of an AC dynamo which needs to be adjusted to the length of fabric used. If the fabric is satin, it requires a large dynamo voltage. Future suggestions, this machine can be used by mosques and prayer rooms that use long prayer mats as well as users such as laundry entrepreneurs, batik entrepreneurs, and relevant fabric companies.
