Abstract

The problem that is often caused by the palm oil industry is the disposal of liquid waste which causes air pollution due to the pungent smell from the waste pool. If it is thrown into the river it will pollute the river and if it is thrown into the ground then the soil will be contaminated. Then an analytical study was conducted so that the liquid waste can be processed by analyzing methane gas whose raw material is liquid waste that is processed anaerobically to fuel the Biogas Power Plant. One of the large plantation potentials obtained from Palm Oil Mills (PKS), which processes Palm Oil Fresh Fruit Bunches (FFB) into Crude Palm Oil (CPO), is biomass waste with a fairly large amount in the form of organic waste in the form of empty coconut bunches. palm oil (Tankos), shells and coir, and liquid waste (Palm Oil Mill Effluent/POME). POME has high energy potential, but in general it has not been used optimally. POME is decomposed in sewage ponds left to decompose naturally. Converting POME into biogas to be burned can produce energy while reducing the impact of climate change. This gas appears as a result of the anaerobic breakdown of organic compounds. Organic liquid waste generated during palm oil production is a major energy source that has not been widely utilized in Indonesia. Converting POME into biogas to be burned can produce energy while reducing the impact of climate change.

Abstract

Maintenance is an activity to keep the machine/production equipment, and make repairs or replacements to increase production in the industrial world. There are several types of maintenance developed, namely Preventive maintenance, corrective maintenance, and predictive maintenance. Maintenance techniques on direct object measurement monitoring are more applied to the industrial world because it is done without stopping operation on a machine, this treatment technique is also called predictive treatment, and requires analysis to monitor engine conditions, such as the measurement of vibration signals. Each vibration signal generated has different damage. Misalignment is one type of damage caused by the frequent vibration of the shaft and clutch. The vibration signal generated by misalignment has its own characteristic seen in the vibration spectrum. In this undergraduate task will be analyzed angular misalignment vibration signal at feed water pump by taking data at horizontal drive point. The vibration signal at the feed water pump generates angular misalignment through the 3X rpm spectrum where the first rpm is larger than the next two rpm. From the measurement of vibration, it can be seen through the comparison of vibration value to trending with the prevailing standard showing high amplitudes on the horizontal motor drive of 2.65 mm/s based on ISO 10816- 3 standard.

Abstract

Postpaid and Prepaid kWh meters are measuring tools for consumer power consumption, there is a thought that Prepaid kWh meters are more expensive than Postpaid kWh meters. This research is to compare Postpaid kWh meters and Prepaid kWh meters by using varying loads with voltage drop treatments with voltages of 230 volts, 220 volts, 198 volts, and 165 volts. So on the load of the induction motor, LHE, and the load of LHE variations and incandescent lamps with source voltages of 230 volts, 220 volts, 198 volts, and 165 volts, it can be said that the Prepaid KWH-meter has a better KWH rotation than the Postpaid KWH-meter. At various loadings on the kWh meter rotation test, the prepaid rotation speed is longer than the postpaid rotation speed with a difference of 0.53 hours or 32 minutes.

Abstract

The distribution system is divided into primary and secondary distribution networks. The primary distribution network is a network from substation transformers (GI) to distribution substations, while the secondary distribution network is a channel network from distribution substation transformers to consumers or loads. The primary distribution network is better known as the medium voltage network (JTM 20kV) while the secondary distribution network is the low voltage network (JTR 220/380V). The distribution network is the part of the electric power system that is closest to the customer or the load compared to the transmission network. At this time PT. PLN (Persero) experienced a power loss that occurred at the connection point of the low voltage network (JTR) on the use of a piercing connector. This study is to analyze the calculation of power loss on a low voltage network (JTR) by comparing the measurements between the input and output at the connecting point of the piercing connector with the line tap connector. With these conditions, it is necessary to evaluate and analyze for re-planning that takes into account planning criteria such as voltage drops and takes into account power losses for the sake of continuity of electricity services so that optimization appears on the network used.

Abstract

The function of technology in fisheries is a renewable innovation that is needed by fishermen. From fishing patterns that were previously only based on tides and the position of the moon, now using technology fishermen can find out which locations have a lot of fish so that they are more efficient and don't take a long time and luck. in catching fish in the sea. The design of a system that initializes fish objects using sonar by utilizing marine acoustics is expected to help increase fishermen's catches. The system is built by utilizing the Arduino UNO microcontroller and echosounder as well as an Android smartphone that will display readings from the echo sounder.

Abstract

Stator adalah bagian dari generator yang tidak bergerak, terdiri dari kumparan kawat penghantar yang disusun sedemikian rupa dan ditempatkan pada alur-alur inti besi. Pada penghantar merupakan tempat terbentuknya ggl induksi yang merupakan hasil dari medan magnet yang berputar dari rotor yang merupakan kumparan penghantar stator. Besarnya tegangan listrik yang dihasilkan oleh generator pada suatu pembangkit listrik biasanya dalam bentuk volt. Pada saat generator beroperasi akan terjadi hubungan pendek berupa panas yang terjadi pada rotor dan stator generator. Untuk mengurangi panas yang terjadi, setiap generator memiliki sistem pendingin tersendiri untuk mendapatkan temperatur yang sesuai sehingga dapat beroperasi dengan normal. Generator yang memiliki kapasitas besar (>300 MVA) umumnya menggunakan gas hidrogen sebagai media pendinginnya. Kelebihan gas hidrogen sebagai pendingin adalah memiliki perpindahan panas yang baik dan menghasilkan jumlah yang relatif kecil sehingga panas yang dihasilkan kecil.
