Abstract In this study, we will discuss the process of casting used aluminum metal. Used aluminum is one of the industrial wastes that can be converted into products using the casting method. This study aims to obtain a good casting material with good hardness values and minimal defects. The research will focus on the results of castings by analyzing the visuals and hardness values of the specimens. The research design is a pre-experimental type of One-Shot Case Study by conducting treatments whose results will be directly observed and analyzed descriptively. The treatment given is to increase the number of risers in recycled aluminum castings. Variations in the number of risers are 1 riser, 2 riser, and 3 riser. Each variation has 3 specimens, so there are 9 specimens in the study. The data from the test results contained a fairly large porosity value for each riser variation. The hardness value that has been tested using the Rockwell hardness tester obtained the highest hardness value occurs in the 2 riser variation, namely 27.69 HRA and the lowest hardness value occurs in the 3 riser variation, namely 21.56 HRA. Thus, for casting used aluminum with a casting pattern as in this study, it is best to use 2 risers.

The Cross-flow turbine is one type of hydroelectric power plant that is frequently used. This is an experimental study with the goal of analyzing the power and efficiency produced by the turbine as a result of runner rotation adjustments. The runner rotation variations used are 261 rpm, 300 rpm, 320 rpm, 340 rpm, 360 rpm, 380 rpm, 392 rpm, and 423 rpm with a head as high as 5 meters and an incoming water discharge of 0.2 m3/s. The best results shown when runner rotate at 423 rpm. It's showed the maximum power 788.85 Watt and best efficiency 80.49%. The power and efficiency produced by a runner are proportional to the rotational speed of the runner; the higher the runner's rotation, the greater the power and efficiency produced. To summarize, the best way to achieve the best turbine performance is to maximize runner rotation. Salah satu jenis pembangkit listrik tenaga air yang sering digunakan adalah turbin tipe Cross-flow. Penelitian ini berupa penelitian eksperimen yang bertujuan untuk menganalisis daya dan efisiensi yang dihasilkan turbin akibat perubahan putaran runner. Variasi putaran runner yang digunakan yaitu 261 rpm, 300 rpm, 320 rpm, 340 rpm, 360 rpm, 380 rpm, 392 rpm, dan 423 rpm dengan head setinggi 5 meter serta debit air yang masuk 0,2 m3/s. Hasil penelitian menunjukkan daya dan efisiensi maksimum didapatkan pada putaran runner 423 rpm yaitu 788,85 Watt dengan efisiensi 80,49%. Terbukti bahwa daya dan efisiensi sebanding dengan kecepatan putaran runner, semakin tinggi putaran runner maka daya dan efisiensi yang dihasilkan juga semakin besar. Dapat disimpulkan, untuk mendapatkan kinerja turbin yang maksimal yaitu dengan memaksimalkan putaran runner.

Nagari Gurun terletak di Kecamatan Harau, Kabupaten 50 Kota. Topografi nagari Gurun yang berbukit-bukit menjadikan nagari ini berpotensi untuk pengembangan tanaman serai wangi dan industri pengolahan minyak atsiri dari daun serai wangi. Pengolahan tanaman sereh wangi memberikan kontribusi besar dalam peningkatan perekonomian masyarakat lokal. Sebagian masyarakat lokal telah membudidayakan tanaman serai wangi dan telah memiliki alat penyulingan. Namun, alat penyulingan tersebut masih sederhana, berkapasitas kecil, dan belum efektif serta efisien karena masih banyak uap yang terbuang dari mesin penyulingan sehingga meningkatkan konsumsi bahan bakar. Oleh itu, melalui Program Kemitraan Masyarakat maka solusi yang ditawarkan adalah penerapan alat penyulingan serai wangi yang memiliki kapasitas lebih besar, berteknologi sehingga proses penyulingan lebih baik, dan efektif dan efisien. Kegiatan PKM ini meliputi desain alat penyulingan, pembuatan mesin, dan pelatihan penggunaan alat. Mesin penyulingan yang dibuat adalah bejana yang didesain secara khusus untuk menyuling serai wangi yang dilengkapi dengan pengukur temperatur, tekanan, dan katup pengaman supaya penyulingan lebih efektif dan efisien. Hasil menunjukkan bahawa hasil sulingan lebih banyak dalam waktu penyulingan yang sama sebelum menggunakan mesin PKM.

This study aims to examine the performance of pico hydro scale cross flow water turbines using multilevel double penstock as a conductor of water flow. Multilevel double penstock is used to reduce the transportation process from highways that are affordable to four-wheeled vehicles / cars to the location of the installation of the turbine. This condition causes the need for small-scale water turbine designs with lightweight construction with a kock down system. Overall the picohidro scale turbine construction is needed relatively cheaper transportation costs, so that people who have not been reached by the PLN network can be touched by small and cheap electricity. Turbine construction data has a runner diameter of 170 mm, body dimensions 200 mm x 300 mm x 250 mm, frame 250 mm x 800 mm. Pool tando 600 mm x 1200 mm and penstock length 16m. The power produced is theoretically around 2500 watts, with a data flow of 50 liters / second and a water level of 8 m. 65% efficiency. The research method is analyzing the double penstock water flow, by making paralon pipes in stages, ranging from 5 incci diameter, 4 inches and 3 inches, flow analysis approach using a gradient line, where the incoming water velocity and water velocity come out until entering the transmitting pipe. The performance results of this turbine provide an average actual power of up to 2000 watts. The stability of the inlet water condition is used by the Tando pond as a water bath. If there is excess water in the sediment tank, the water gate is used out, where excess water will automatically flow into the exhaust channel.

Energy consumption of a building is one of the biggest sources of energy use today. Green Building Comitte Indonesia (GBCI) has launched a concept of energy consumption saving in a nationally standard building. Audit Building energy audit is the way to know how actual building energy consumption is and find alternative solution to decrease energy consumption in order to fulfill the energy saving building criteria. Two types of HVAC systems will be run in the EnergyPlus simulation, split AC and central AC. The previous research proved that central AC is better than split AC system for energy saving in the building with 20 floors. The simulation results show that by using a certain energy system, a more efficient energy system will be achieved and can still maintain the comfort of the room at a temperature of 24 °C and relative humidity according to the Green Building Indonesia standard reference.

The development of digital technology for education is continuously conducted to successfully integrate digital technology with people's lives. This study aimed to develop an Augmented Reality learning media application for the Engineering Mechanics course, which is considered challenging by some students. Engineering mechanics, a discipline that analyzes structural analysis in compensating for the loads that work on a particular machine in scalar quantities, motion forces, vectors, and moments that require physical structural forms to analyze them, is considered challenging by some students. The Augmented Reality application was created using the prototyping method, which consists of three steps: 1) listening to the customer, 2) building/ revising mock-up, and 3) customer test-drivers mock-up. The AR-based learning media application includes usage instructions, developer info, learning videos, 3D AR object animation simulations, and exercise and discussion menus, which were tested as expected. The results of the black box testing indicate that the Augmented Reality-based engineering mechanics learning media application ran successfully as expected. However, users suggested improving the navigation speed by streamlining page transitions. The application provides an accessible solution for students as an alternative to traditional distance education, offering anytime, anywhere access to learning materials with longer duration.
