Abstract

Simulator sistem hidrolik atau yang lebih dikenal dengan hydraulic training unit merupakan alat pembelajaran yang digunakan untuk memahami sistem hidrolik. Pada hydraulic training unit terdapat tiga jenis katup pembatas tekanan yaitu; relief valve, flow control valve dan shut off valve. Tujuan riset ini yakni untuk mendapatkan energi listrik yang optimal pada rangkaian sistem hidrolik dengan mengatur pembukaan katup pembatas tekanan. Metode yang digunakan adalah dengan melakukan pengukuran tegangan, arus dan faktor daya yang terjadi pada masing-masing pembukaan katup pembatas tekanan. Menghitung daya listrik serta menghitung daya mekanik dari rangkaian sistem hidrolik. Melakukan optimisasi menggunuakan linier programing dan di uji menggunakan software Lindo.. Hasil yang diperoleh, pada rangkaian silinder hidrolik, pembukaan ¼ relief valve merupakan pembukaan optimal, energi listrik yang terjadi 390,6 Watt Jam. Pembukaan ¼ flow control valve merupakan pembukaan optimal, energi listrik yang terjadi 390,68 Watt Jam. Pembukaan ¼ shut off valve merupakan pembukaan optimal, energi listrik yang terjadi 390,68 Watt Jam.

Abstract

The need for a reliable and continuous power source to supply electrical loads is very important. In order for continuous electricity supply, a system of Automatic Transfer Switch - Automatic Main Failure (ATS - AMF) is needed. This system will automatically divert electrical power from the main PLN source to a backup source. The stages in the design of this tool include ATS-AMF planning, component assembly process, and box panel assembly. The result is a 380 V, 50 Hz ATS/AMF panel based on the LS Master K120s PLC which is supported by both manual and automatic operating systems. For the AMF system using the PLC LS Master K120s, the generator set is set for 3 seconds after the supply from PLN goes out and will immediately supply electrical energy after 5 minutes after the generator is running. When PLN returns to normal for 5 minutes the generator set will be separated from the system, the generator will cool down, then the generator will stop. The ATS-AMF system works as described for which it was designed.

Abstract

Wind turbines are one of the machines that are currently still used to convert wind kinetic energy so that they can be used by humans such as to drive pumps in agriculture and produce electrical energy. Savonius turbine is a vertical axis turbine that is currently widely used as an electrical energy generator, this wind turbine is a type of drag type wind turbine that has a simple design that is in the form of a semicircular curved blade side. Therefore, the author is interested in researching the resulting performance including turbine rotational speed, power generated, and wind turbine efficiency against the variation of the blade radius. The method used is experimental, the stages of this research are in the form of literature studies, making savonius turbines, testing savonius turbines with variations in blade radius as well as data retrieval, data processing, and analysis. Based on the data obtained, the rotating speed of the turbine is influenced by variations in the radius of the blade. The larger the blade radius, the smaller the turbine rotational speed. The maximum turbine rotation speed at blade radius 63 is 173 rpm, while at blade radius, 88 is 118 rpm and at blade radius 113 is 115 rpm. So the highest turbine rotating speed at a radius of 63.

Abstract

Ketersediaan tenaga teknisi AC jumlahnya sangat terbatas sehingga konsumen pemakai AC yang ada di kota Pontianak jika membutuhkan tenaga teknisi mengalami antrian, karena terjadi ketidakseimbangan antara kebutuhan dan ketersediaan tenaga teknisi AC. Parit Tokaya merupakan salah satu kelurahan yang ada di kota Pontianak, berada di kecamatan Pontianak, dimana berdasarkan hasil muresbang untuk usulan anggaran 2021 dinyatakan bahwa masih banyak anak putus sekolah yang berada di kelurahan Parit Tokaya. Berdasarkan data tersebut di atas, maka sasaran kegiatan PKM teknik Mesin salah satunya adalah Pelatihan teknisi AC. Tujuannya menumbuhkan semangat berwirausaha bagi masyarakat melalui pembentukan kelompok usaha dan memberdayakan potensi masyarakat dalam meningkatkan pendapatan keluarga melalui peningkatan usaha ekonomi produktif. Metode pelatihan yang digunakan adalah dengan memberikan materi teori dan praktik serta tanya jawab. Hasil dari kegiatan ini adalah peserta menjadi termotivasi untuk mengikuti pelatihan karena mereka dapat melanjutkan hasil pelatihan dengan berwirausaha. Hasil evaluasi terhadap kegiatan pelatihan hampir semua peserta merasakan puas dan menanggapi positif pelatihan ini.

Abstract

Plastic extruder machine is a machine that processes material changes from the form of plastic making into extruded changes from solid to liquid form. In the plastic extruder machine there are many machine components used. The components found in the plastic extruder machine are the frame, reduction gear, puller roller, bearing, v-belt, electric motor, pulley, stepper, clutch, air chamber, nozzle, feeder, compression spring, panel box and screw. This study uses an experimental method by changing the screw diameter which was originally 37 mm to 41 mm in addition to changing the diameter size, changes were also made to the screw pitch size which was originally 12 mm to 14 mm. The modified screw that was tested using PLA material with a rotation of 38 rpm produced a flow rate of 0.00129 m ^ 3 / s with a maximum pressure of 10.2866 Mpa. While the screw before modification produced a flow rate of 0.000921 m^ 3 / s and a maximum pressure of 9.5151 Mpa. From the data obtained from the screw, the modification results obtained quite good results compared to the screw before modification.
