Renewable energy is energy derived from nature and can be produced continuously such as water energy as a micro hydropower plant. The development of a micro hydropower plant is to utilize the potential energy of water flow that has a certain head and discharge to be converted by turbines and generators into energy electricity that can be used in the development of Archimedes Single Screw Turbines. Archimedes Single Screw Turbine is a type of turbine that is capable of operating with low head 1-15 meter in river flow and irrigation. Aceh is one of the regions that have a large amount of water energy potential to be used as energy driving water turbines. The purpose of this study is to design, make Turbine Archimedes Single Screw construction and conduct turbine testing and determine the performance of Archimedes Single Screw Turbine based on the effect of water flow discharge on rotation, torque, power, and optimum efficiency so that it can determine the right turbine design and performance well. Archimedes Single Screw turbine is made with 201 stainless steel which has dimensions of N = 1 blade (Ro= 130 mm, Ri = 70 mm) with pitch 2Ro, Turbine length (L = 2 m), head = 1 m, Angle θ = 300. The variables measured and observed are the rotation of the turbine, torque, and flow rate. Tests were carried out on 3 variations of flow rate, namely 0.02 m3/s, 0.009 m3/s, and 0.003 m3/s. The test results, the highest rotation, and turbine power occur at flowrate 0.02 m3/s at 236.40 rpm with a power of 116.10 watts and maximum turbine efficiency is 57%. Thus, the turbine with maximum power and efficiency is obtained when the flow rate is 0.02 m3 /s.

Tape merupakan makanan tradisional yang banyak dikonsumsi oleh masyarakat. Tape dibuat menggunakan ragi dengan cara difermentasi selama 3-4 hari yang ditutup menggunakan daun pisang untuk menghasilkan rasa yang manis. Disamping itu tape juga mengandung alkohol dari hasil fermentasi ragi dan beras, jika terlalu banyak mengkonsumsi tape, maka badan akan terasa panas karena tidak mengetahui berapa persen alkohol yang mengandung pada tape tersebut. Untuk mengatasi hal seperti itu terjadi maka perlu dirancang alat pengukur kadar alkohol pada makanan tape agar bisa mengetahui persentase alkohol pada tape tersebut. Rangkaian Perancangan Alat Pendeteksi Persentase Alkohol pada Makanan Berbasis Arduino Uno terdiri dari tiga bagian, yaitu bagian input, bagian kendali dan bagian tampilan. Dibuat untuk mempermudah proses Perancangan Alat Pendeteksi Persentase Alkohol pada Makanan berbasis Arduino Uno. Dimana sensor MQ3 digunakan sebagai masukan untuk mendapat hasil persentase alkohol dari tape, Arduino Uno dapat terprogram secara real time dan hasil data persentase akan ditampilkan di LCD I2 Inc. Berdasarkan hasil pengujian dapat disimpulkan bahwa sensor MQ3 yang berfungsi sebagai input dan mengeluarkan output berupa suara pada buzzer. LCD berfungsi sebagai menampilkan persentase alkohol pada tape. Pengujian yang telah dilakukan mendapatkan hasil kandungan persentase alkohol pada tape dengan pengujian lima hari berturut-turut dengan rata-rata yaitu, 22%, 39%, 46%, 57%, dan 67%.

As technology advances, the development of equipment used by humans is increasing and most of the equipment produces unwanted sounds that cause noise. To overcome this, an alternative material for soundproofing is needed which is relatively cheap and easily available in the community by using marble powder as a polyurethane mixture in soundproof panels. The purpose of this study was to determine the effect of the sound absorption coefficient value and to determine the relationship between the frequency of the sound source and the sound absorption coefficient of acoustic materials using marble powder mixed with polyurethane in different compositions. The sound absorption test in this study was carried out using a two-microphone impedance tube and has a frequency limit of 125 Hz - 4000 Hz, variations in the mass composition of marble and polyurethane powder 1: 1, 1: 2 and 1: 3 with a thickness of 5 cm, 3cm and 1 cm. Then the test results of the 1: 1 test specimen, the lowest sound absorption coefficient value was obtained 0.10 0.73 cm-1 at a thickness of 1 cm with a frequency of 4000 Hz and the highest was 0.73 cm-1 at a thickness of 5 cm with a frequency of 125 Hz, the test results 1: 2 test specimen, the lowest sound absorption coefficient value is 0.29 cm-1 at a thickness of 5 cm at a frequency of 4000 Hz and the highest is 0.67 cm-1 at a thickness of 5 cm at 250 Hz, then the test results of the test specimen are 1: 3 values The lowest sound absorption coefficient was 0.24 at a thickness of 1 cm at a frequency of 4000 Hz and the highest was 0.71 at a thickness of 5 cm at a frequency of 250 Hz. For the comparison of the sound absorption coefficient values based on the composition and thickness, the lowest and highest sound absorption coefficient values are found in 1: 1 specimens with a thickness of 1 cm and 5 cm with the best sound absorption coefficient values on average at a frequency of 500 Hz, but in material 1:2 and 1:3 obtained the sound absorption coefficient values are in between on the grounds that the thicker the material, the higher the sound absorption coefficient value. Thus it can be concluded that the polyurethane composite material mixed with marble powder can be used as a sound absorbing panel material, especially in a 1: 1 composition

Indonesia is one of the maritime countries so that most of Indonesia's territory is the sea, which is rich in marine product; fish is one of the marine products. Fish is a commodity that is not durable and easily damaged if placed in open place. The main causes of fish damage include the activity of microorganisms and bacteria in the fish meat, where at room temperature bacteria and microorganisms can multiply rapidly. Therefore, the author makes a cold storage cooling system with a 10 kg capacity, which can be used to cool the fish caught by fishermen so that the quality and quality of the fish is still fresh to consumers or buyers so that can increase the selling price of fish caught by fishermen in South Aceh Regency. The cold storage manufacturing method is carried out with the initial process of measuring, cutting, welding, drilling, joining, vacuuming and electrical installation. The tools used in the process of making cold storage are welding machines, acetylene welders, cutting grinders, rubbing grinders, measuring elbows, meter tubing cutters, vacuum pumps, digital scales and clam meters. The materials used are angle iron, cold storage boxes, electrodes, relays, MCBs, elbows, and thermostats. The benefits generated by the manufacture of cold storage are to cool fish and increase knowledge of how the system works in cold storage for students of the South Aceh Polytechnic. The results of the cold storage trial for 30 minutes operate with an outside cold storage temperature of 270C and a cold storage temperature of -200C.
