Abstract

Sudah menjadi pengetahuan umum bahwa industri manufaktur perkembangannya semakin meningkat dari waktu ke waktu sehingga para pelaku industripun harus selalu siap berkompetisi. Masalah dan faktor-faktor yang berhubungan dengan peningkatan produktifitas tetap perlu dan layak untuk diteliti agar tercipta peningkatan produktivitas yang sesuai dengan harapan dari para pelaku industri. PT. XY  merupakan salah satu perusahaan mainan anak yang ingin melakukan perbaikan metode kerja dan waktu kerja dalam usaha meningkatkan produktivitas. Metode yang digunakan dalam penelitian ini adalah menggunakan Micromotion Study dan Kaizen yang kemudian dituangkan dalam peta tangan kiri dan tangan kanan. Pengolahan data dan pembahasan dilakukan dengan membuat data pengukuran yang terdiri dari waktu perakitan  sebelum dan sesudah menggunakan analisis Micromotion Study dan Kaizen, data pengamatan tersebut kemudian dituangkan dalam peta tangan kanan dan tangan kiri. Tujuan dari penelitian ini adalah mendapatkan perbaikan rancangan kerja (redesign) dan pengurangan waktu pekerjaan di bagian perakitan balok dan pengemasan.

Abstract

Gondola is one of the facilities used in high-rise buildings that are used to access the outside of the building. Gondola has a maximum load limit that is safe to transport it. Gondola is also often damaged in the cage caused by collisions on the side of the building. Until now, the gondola control still uses buttons which also often experience problems. This study aims to provide monitoring of the cage load and provide information about the distance of the cage to surrounding objects. Gondola control through an android application also includes this research in order to provide an alternative if the buttons on the gondola control experience problems. The short-term goal of this research is to carry out an innovation in the gondola field by conducting experiments through prototypes. The medium term goal is to apply the results of this research into a gondola. The results of this study control and monitoring can function properly even though the results produced are not yet accurate due to the imperfect quality of components, materials and assembly.

Abstract

Turn ratio test is a comparison test of the number of secondary turns with the primary turns on the transformer. The turns ratio and group vector testing is one of the routine transformer tests. This test generally uses the Transformer Turns Ratio (TTR) test tool, the test equipment used sometimes experiences technical and non-technical problems so a comparative test method is needed to get a good analysis. The research method used is observational research and literature study, namely analyzing the transformer to be studied by conducting TTR testing in two ways, namely testing with test equipment and three-phase low voltage sources, aiming to obtain a very good level of accuracy. The test results were analyzed and compared with theory and calculations, with reference to the IEC 60076-1 standard. The results of the comparison of windings and group vectors using TTR 100 test equipment and a 3-phase low voltage source (TVR) show the same conclusions as the results of the analysis, where the first transformer sample is in normal condition and meets the requirements. SPLN D3.002-1:2007 or IEC Standard 60076-1. While the second sample transformer is in an abnormal condition in the W winding where the difference value is above 0.5%.

Abstract

Nowadays, the quality of electrical energy really needs to be improved especially for industrial purposes that require a good level of reliability in the distribution of electrical energy. Maintenance of distribution transformers is routinely carried out to ensure that the quality of electrical energy produced is in accordance with standards. This maintenance is done using the customer’s load from the distribution transformer to the mobile substation transformer, that can be done using synchronization. This synchronization requires the same distribution transformer vector groups, otherwise it will produce non-standard output. The aim of this research is to determine the vector groups effect on parallel transformer installation system, the method to overcome the synchronous problem of different vector groups based on simulating and testing the synchronization of a 20 / 0.4 kV distribution transformer with the Dyn5 and Dyn11 vector groups. The results obtained from this research are two transformers that have different vector groups can be synchronized with an abnormal connection (changing the position of the secondary terminal cable connection and the primary terminal cable) so that it will produce the same voltage phase. This will abnormal treatment of distribution transformers maintenance that do not have a back-up transformer with the same vector group still can use the different vector group transformers.

Abstract

ABSTRACTFuel Oil (BBM) is one of the fuels that have been used to drive most of vehicles such as motorcycles. The authors did the research on motorcycles using electrical energy to be more environmentally friendly. Experiments were done by using the direct test method and analyzing the obtained data to determine how much power was released and how much battery capacity was used to drive an electric motorcycle with variations of the driver's weight as much 60 Kg, 90 Kg, and 125 Kg and speed variations such as 10 Km/Hour, 20 Km/Hour, 30 Km/Hour, and 38 Km/Hour. The experimental results shows that the greater the weight and the speed of the motorcycle, the greater the power and capacity of the battery, so that could be concluded that the use of the battery on the motorcycle becomes more wasteful and the battery life will be shorter.ABSTRAKBahan Bakar Minyak (BBM) menjadi salah satu bahan bakar yang digunakan untuk menggerakkan kendaraan seperti sepeda motor. Penulis melakukan penelitian pada sepeda motor menggunakan energi listrik agar lebih ramah lingkungan. Dilakukan percobaan dengan metode uji coba langsung dan menganalisis data yang didapat untuk mengetahui seberapa besar daya yang dikeluarkan dan seberapa besar kapasitas baterai yang digunakan untuk menggerakkan sepeda motor listrik dengan variasi berat pengemudi yaitu 60 Kg, 90 Kg, dan 125 Kg dan variasi kecepatan yaitu 10 Km/Jam, 20 Km/Jam, 30 Km/Jam, dan 38 Km/Jam. Hasil percobaan menunjukkan semakin besar berat beban dan kecepatan pada sepeda motor, maka daya dan kapasitas baterai semakin besar dikeluarkan sehingga penggunaan baterai pada sepeda motor menjadi lebih boros dan ketahanan pada baterai semakin sebentar.

Abstract

Nowadays, energy sources in the world at the end until now tends to be filled using fossil fuels. It is estimated that the world energy consumption until 2025 is still dominated by fossil fuels, namely oil, natural gas and coal. The Ministry of Energy and Mineral Resources said that petroleum dominates 54% of energy use in Indonesia. One way to overcome the use of fossil energy sources is to replace them with renewable energy especially photovoltaic. Therefore, this paper presents solar charge system using Buck Converter PID Controller for Spotlight load. Buck Converter with PID Controller is used to produce a smaller and more stable output voltage from solar panels of 14.4 Volts for charging the battery. The PID parameter values ??obtained after performing calculations using the Analytic Tuning method and tuning are Kp = 0.0307, ??Ki = 58.20 and Kd = 0.000263. The expected result of this research is to design and implement a solar charge controller as a producer of electrical energy from environmentally friendly energy.
