Drying is a process that aims to prevent decay. However, the natural drying process can produce less than optimal results, especially during the rainy season. Uncertainty about the use of solar energy triggers to conduct this research. In addition, it takes a long time and requires a large area during the drying process, so this research aims to provide a more optimal value in terms of efficiency by using a rack-type egg tray drying machine. The dimensions of the shelf-type egg tray drying cabinet are 500 x 500 x 900 and a control box. The heating elements are arranged in parallel consisting of 3 tubular heating elements. The thermal efficiency generated in the rack type egg tray drying machine with an average thermal efficiency value of 32.18% and the highest thermal efficiency value produced on the first rack reached 38.32%

The sand sieving process is an activity that we often encounter in infrastructure development projects. But in the case of observations, problems are often encountered where workers still rely on simple or manual equipment. Based on the observations of the cases found, a semi-automatic sand sieving machine will be designed to help construction workers. In the process of making a sand sieve machine using a 9Â° sieve tilt angle with a sieve area of â€‹â€‹3250 cmÂ² and using a 0.5 cm x 0.5 cm mesh type. The driving source of the sand sieving machine uses an AC 0.5 HP electric motor with 1420 rpm. The eccentric shaft has a rotational speed of 115.36 rpm after receiving rotation from the AC motor. There are several tests on the sand sieving machine including tool functional testing, tool feasibility testing, and tool testing. In the functional test of the tool, testing all parts of the sand sieving machine obtained an average test value of 95%, in the feasibility test of the tool an average value of 100% was obtained, with a score of 4 and for testing the tool which included sand sieving, the average value has obtained the average of fine sand testing is 16.46 Kg and coarse sand is 3.53 Kg in 17.48 seconds, so it can be seen that the sand sieving machine can work optimally.

The development of a plastic waste chopper machine with a gearbox transmission system was carried out because in previous studies there were still shortcomings, namely not being able to operate optimally because during the enumeration of plastic waste there was often a slip on the v-belt. So that this development is carried out using a gearbox transmission system so that the rotation when chopping is more leverage. The research method used is the R&D (research and development) method, a method or step to produce new products or develop existing products, and is used to test the effectiveness of the product. For engine specifications, it uses an electric motor with a speed of 1400 rpm, and a gearbox transmission system with a ratio of 1:50 as a transmission between the motor and the blade shaft. This study uses a type of PET plastic glass waste to be chopped. The results of the minimum engine speed of 16.6 rpm, gearbox output rotation of 28 rpm, rotation of the knife shaft 27 rpm, the value of the force on the count of 9.8 N, the pulley rotation of 1200 rpm, the ratio of the chain rotation speed of 1.037 and the number of connected sprockets. the gearbox has 46 teeth, while the sprocket connected to the blade shaft has 44 teeth. So that the resulting engine capacity is 1.02 kg/hour. In addition to the results of machine calculations, machine validation tests were also carried out that for the engine design assessment of 81.25% with very good criteria, engine function of 91.6% with very good criteria, while the calculation of machine capacity was 85% with very good criteria.

Hydroponics training at the Indonesian School of Davao (SID) Philippines aims to improve students' skills in growing crops using soilless methods. Hydroponics is an effective solution for sustainable agriculture in countries with limited land. This training was carried out in three stages: pre-activity, implementation, and evaluation. The pre-activity stage identifies problems in implementing modern agricultural technology in schools. During implementation, students gain theoretical and practical understanding of hydroponic systems, including planting media selection, plant care, and nutrient management. Evaluation is carried out to assess the skills students acquire after training. Participants' response to the training reached 97%, reflecting high satisfaction and interest in the material presented. These findings confirm that hydroponic training can be an effective solution in preparing students to face the challenges of sustainable agriculture in the future. The results of the training show that students are able to manage hydroponic systems independently and understand the importance of environmentally friendly agriculture, as well as the skills needed to face agricultural challenges in the future.
