Protection system is a very important component in the electric power distribution system. With good reliability, the distribution of electrical power will be better, one of which is by minimizing disruption to the system quickly, precisely and accurately. Components used in protection systems are directional overcurrent relays (DOCR). In this study proposed optimal and adaptive protection coordination using the Modified Firefly Algorithm-Artificial Neural Network (MFA-ANN) tested on the IEEE 9 real bus loop system with 4 generation combinations. Optimization using MFA will get the Time Delay Setting (TDS) and Ipickup (lowset) values. The ANN used is Backpropagation Lavenberg Marquardt (BPLM) After the BPLM learning process, we will get the weight and bias values of the training results and later as a reference value to get the value of TDS and Ipickup relay. The process will produce relay settings automatically based on the results of optimization and MFA-ANN training which are then simulated on the IEEE 9 bus loop system. The results achieved by MFA-ANN are suitable methods for modeling optimal and adaptive relay coordination systems. ANN training with the BPLM algorithm produces the smallest MSE value of 5.9308xE-10.

Salah satu komponen dari sistem distribusi adalah gardu distribusi. Gardu distribusi berfungsi untuk menghubungkan jaringan ke konsumen Salah satu komponen terpenting dari gardu distribusi adalah transformator. Karena penempatannya di tempat terbuka, transformator sering mengalami gangguan akibat sambaran petir. Selama kurun waktu 2017-2019 pada Penyulang Subagan mengalami gangguan akibat impuls petir sebanyak 10 kali. Penelitian ini membahas cara kerja lightning arrester dalam memproteksi peralatan dengan konstruksi model lama dan setelah dilakukan perubahan posisi, jarak proteksi ideal lightning arrester dengan transformator, kinerja lightning arrester setelah dilakukan perubahan posisi pada konstruksi yang baru, dan dampak dari perbedaan konstruksi dalam pemasangan lightning arrester di ULP Karangasem. Dari hasil analisis, dengan kondisi iklim di wilayah Karangasem jarak proteksi maksimal lightning arrester dan transformator adalah 6,2245 meter. Jarak lightning arrester dan transformator dengan konstruksi lama yang ada di lapangan adalah 1,5 meter. Dimana jarak tersebut membuat arus puncak petir yang mampu diterima dari lightning arrester sebesar 178,3032 kA, sehingga dapat dikatakan jarak lightning arrester dan transformator dengan konstruksi lama masih dapat bekerja dengan maksimal. Setelah menggunakan konstruksi baru sesuai dengan SPLN D5.006. 2013, jarak lightning arrester dan transformator di KM 0003 menjadi 0,6 meter. Jarak tersebut membuat arus puncak petir yang mampu diterima dari lightning arrester menjadi lebih tinggi yaitu 655,008 kA, dan terjadi peningkatan kinerja lightning arrester sebesar 267,36 % akibat perubahan posisi.

ABSTRACT: The Padangsambian Kelod area is one of the densely populated areas. This causes changes in the land use function from rice fields to housing, which reduces water infiltration, causing surface runoff. So that the author needs to calculate the flood discharge and drainage planning in the area. The stages in calculating flood discharge to planning drainage channels include looking for stations that affect, namely Ngurah Rai Station, Sanglah Station, Ship Station, conducting existing drainage channels. After that, calculate the total rainfall and maximum rainfall, which means that the data will be used for further calculations such as the consistency test of the Double Mass Analysis method, calculating the regional average rainfall, testing the selection of distribution, calculating rainfall, design the Log Person Type III method, calculating Rain intensity (Talbot, Sherman, Ishiguro), Calculating distribution suitability test (Smirnov Kolmogorov), Calculating flood discharge analysis (Rational) to dimensional calculations. In the analysis of the flood discharge, the flood discharge plan for the 5 year return period is 0.049 (m3/s)> the existing flood discharge is 0.030 (m3/s) so it is necessary to plan drainage channels in the Padangsambian Kelod area.

Indonesia is the world's largest island nation with many islands and more seas than land. Because of the size of the Indonesian sea, oceanographic science is needed. Oceanographic learning involves the study of the underwater depths of the batimetric sciences. Batimetric science is crucial because it studies underwater depth. Batimetric processes in Indonesia today generally employ large vessels with manual control, resulting in the skill required of drivers at risk for obtained track data. With the problem, it has been designed to disrupt the autonomous control system with a pid waypoint system that would provide stable direction for the ship. The control system USES the arduino microcontroller which is used for processing data. The data obtained are data coordinates obtained from the GPS and the ship's navigation data obtained from the compass sensors. The data obtained will be processed and applied to pid methods. Of the pid process can be generated the degree degree required to power the servo motor connected to the ship's rudder. In this research USES four coordinate points of starting point, first goal point, second point of destination, and third point of goal. Once it reaches the third point of destination, the ship will return to its starting point. From the results of the testing done, the result is a kostanta pid score of KP =8, ki =5, kd = 3.5. Tests enabled the system that kept the ship's course steady as it should. So the ship goes on track.

The diagrid structure system is a grid structure system that is applied to buildings with a diagonal shape. This structural system aims to increase the strength and stiffness of the building. In addition, the diagrid structural system can provide a more aesthetic appearance. This structural system is very good for application in medium to high rise buildings. In this study, a comparison of the behavior and performance of the Diagrid (DIA) and Brace Frame (BF) structural system using ETABS 2016 software is carried out. The structural behaviors to be reviewed include stress ratio, deformation, drift ratio and structural weight, while the structural performance includes pushover curves. The geometry of the two buildings uses a span length and width of 3@5m and a total height of 30 m. In this study, results obtained from behavioral analysis in the form of stress ratio is less than 1, the deformation of BF was 58% greater compared to the DIA model, drift ratio of DIA was 35% more rigid than BF and the weight ratio of DIA was 24% lighter compared to BF with the weight ratio of 1.33, while for the performance analysis of the DIA model is 14% better than the BF model.

Various kinds of treatments given to solar panels illustrate efforts to increase the output power of solar panels and the efficiency of solar cells. In the following research, we will analyze the differences in the output power and efficiency of solar cells that have received different treatments. In the solar panel that will be analyzed in this study is the addition of a reflector to solar cells with a reflector tilt angle of 90 ° and 60 ° as a form of variation of radiation amplification. The idea for the use of a reflector is to increase the yield of solar cell input radiation. After testing, the output power produced by solar cells increases as the radiation received by the solar panels increases and the efficiency of the solar panels decreases as the temperature of the solar cells increases.
