Abstract

Abstract                There are many low head hydro power energy  resources potential in Indonesia that have not been optimally in use. The main obstacles is that this kind of turbines have low pawer factor and low efficiencies. One of the low head hydro power turbines is Darrieus turbin. The excellence of Darrieus turbine is its simply and has high strength blades.  The verry important parameters that inflence to the turbine performance are width, angle of attack and cross section profile of the blades. The objective of the research is to investigate the influences of  blades width and blades  angle of attack to the  Darrieus turbine performance that using NACA0021 cross section blades. The research has been conducted in a three blades 20 cm diameter 25 cm length Darrieus turbine model. The blades width variations are 5 cm and 6 cm, and angle of attack variations are 00, 50, and 100. It is concluded from the research that the turbine maximum power output is 0.54083  Watt, maximum efficiency is 40.94 %, and maximum power factor is  0.2579 %. These values are reached at  5 cm blades width and 50 angle of inclination.Keywords : Darrieus turbine, NACA 0021,angle of attack, power, performance.

Abstract

Fisheries are one of the sectors that are relied upon for national development. In 2019, the export value of Indonesian fishery products reached Rp. 73,681,883,000, which is an increase of 10.1% from 2018 exports. Marine products such as shrimp, tuna, squid, octopus, crabs and seaweed are sought-after commodities. The development of fish farming can be carried out if the availability of good quality seeds and available in sufficient quantities, proper feed, prevention and treatment of disease and a good living environment. The survival rate at the seed stage is influenced by the type of feed given and the amount according to the needs of the fish. This study aims to modify the previous feed throwing robot so that it can be thrown further and the feed is not destroyed so that it can help the work of fish pond farmers in providing fish feed, modify the tool to help fish pond farmers work in knowing the pond water level, design and build a filling system. manually and automatically using solar panels and modifying the information system on the previous tool so that it can display more information to fish pond farmers. The results showed that the ideal distance of feed throw 5.1 meters, and maximum charging using solar panels 14.28 Watts per hour. The feeding system, water level regulator, information system and charging system can facilitate the pond management process

Abstract

Shelling is one of the post harvest handling for corn farmers where quality and time are important. Shelling that is done traditionally can cause fatigue and take a long time. The corn sheller machine on tricycle electric motorcycles can be used to save time during the shelling process. This research was conducted to design and make a corn sheller machine on a three-wheeled electric motorcycle that can be used to streamline time during the shelling process. In addition, the purpose of this research is to design and manufacture a corn sheller system on a three-wheeled electric motorcycle with a mechanical system with a DC electric motor as a driving force, separate corn kernels from the cob, and test with 1 kg of dry corn. The shelled corn kernels will be directly in the tub of a three-wheeled electric motorcycle while the cob will be thrown out. Based on the results of testing the corn sheller machine on a three-wheeled electric motorcycle, it was carried out twice, namely being able to shell 1 kg of corn with a percentage of crushed corn kernels of 25% for the first test and 35% for the second test.

Abstract

Robot manipulator banyak digunakan dalam aplikasi di industri manufaktur dan diharapkan mampu mencapai kinerja yang baik, mampu meningkatkan akurasi posisi, operasional yang aman, komsumsi energi yang rendah, serta memiliki bobot yang lebih ringan. Penelitian ini dikhususkan pada pembuatan sebuah robot manipulator sebagai prototype dengan memfokuskan pada kondisi gerakan translasi. Dalam penelitian ini juga akan dibuat sebuah alat ukur getaran yang digunakan untuk mungukur frekwensi dan amplitudo percepatan dengan menggunakan accelarometer ADXL 335. Data yang diperoleh akan di tampilkan dalam bentuk grafik FFT frekuensi dan FFT amplitudo percepatan pada software spider. Dengan menggunakan metode Fast Fourier Transform, dapat diketahui frekwensi getaran yang terjadi pada manipulator. Pada penelitian ini menggunakan manipulator dari bahan aluminium dengan panjang 30 cm dan tebal 0,3 cm. Dari hasil pengukuran yang telah dilakukan maka diperoleh frekwensi analisis sebesar 6,71 Hz. Sedangkan frekwensi eksperimen diperoleh sebesar 6,41 Hz. Pada penelitian ini nantinya akan menggunakan sebuah program komputasi yang akan mengontrol pergerakan robot. Metode yang digunakan adalah metode Desain dan Analisis Eksperimental.

Abstract

White oyster mushroom is one type of wood fungus that has native habitat in temperate regions with temperatures ranging from 22-28oC and humidity ranging from 60-80% RH. This mushroom cultivation can be done by storing planting media in a mushroom house (kumbung) by monitoring and maintaining the condition of temperature and humidity. At present the monitoring and maintenance of temperature and humidity is done by manually watering methods by estimating the conditions of the kumbung temperature and humidity. This causes the temperature and humidity conditions only to be estimated manually so that mushroom productivity is not maximal. This study aims to facilitate the mushroom farmers in watering and monitoring the condition of the kumbung. This system consists of sensors placed inside the cage and will detect the temperature and humidity conditions of the cage, temperature and humidity data will then be processed by the controller to enable automatic watering. watering is done with the help of a pump that is equipped with a nozzle to create a mist of water. Based on the results of observations that have been made can be obtained that the system is able to streamline time by watering automatically when the mushroom house conditions are not in accordance with the setpoint. This system is also capable of producing mushroom house conditions that can reduce temperatures to the range of 22-28o C and increase humidity to the range of 60-80% RH in less than 600 seconds. Information on monitoring the temperature and humidity of mushroom houses has been based on internet of things, which is showing the temperature and humidity conditions of mushroom houses through the website according to the data sent by the controller.

Abstract

Peternakan adalah kegiatan mengembangbiakkan dan membudidayakan hewan ternak untuk mendapatkan manfaat dan hasil dari kegiatan tersebut. Sebagian besar peternak di Indonesia masih menggunakan cara tradisional/ konvensional dalam beternak. Bagi peternak berskala besar hal tersebut tentunya menjadi tugas yang sulit untuk menjaga hewan ternak sepanjang waktu. Pemberian pakan, minum, desinfektan, dan pembersih kotoran masih dilakukan secara manual sehingga menyita banyak tenaga dari para peternak. Penelitian ini bertujuan untuk memodifikasi sistem kandang ayam cerdas sebelumnya agar dapat memberikan pakan, minum, disinfektan, dan pembersih kotoran secara otomatis sehingga peternak tidak perlu datang ke kandang secara langsung. Sistem tersebut memerlukan komponen-komponen yang menggunakan sumber daya listrik yang besar sehingga penggunaan Solar Panel (Tenaga Surya) sebagai sumber daya listrik dapat menghemat penggunaan listrik pada alat kontrol yang dibuat. Hasil penelitian menunjukkan bahwa penggunaan Solar System sebagai sumber daya listrik utama pada kandang ayam cerdas yang dibuat berhasil diaplikasikan untuk menyalakan serta menjalankan semua aktivitas yang telah dijadwalkan pada alat. Mekanisme pembersih kotoran kandang yang telah dibuat dapat bekerja sesuai dengan jadwal yang telah ditentukan. Pemberian pakan, minum, disinfektan, dan pembersih kotoran dapat dipantau melalui aplikasi monitoring.
