Abstract

The Electricity System in Bali continues to experience growth every year, where increasing demand for electricity is affected by the increase in the number of electricity consumers in one phase and consumers of electricity in three phases. The Gas Diesel Power Plant (PLTDG) in fulfilling the electricity needs in Bali can supply 200 MW of electricity, sourced from 12 generators. Along with the increase in various types of electricity consumers in Bali, the problem arises in the PLTDG Pesanggaran, namely the occurrence of unbalanced current. A large unbalanced current can cause a trip or a sudden death at the PLTDG Pesanggaran’s generator.Based on the results of the study, the percentage of unbalanced current that occur in the PLTDG in normal conditions ranges between 2% to 3%. But at the time of the trip to the unit 6 generator due to unbalanced current, the percentage of unbalanced current that appeared on the generator just before the trip was 21.69% and has been going on for more than 58 minutes, which exceeds the setting of the relay which only allows a percentage unbalanced current under 8% with a maximum time of 58 minutes. During the trip, the generator only operated 1 unit in block 2, so the magnitude of the unbalanced carried by the generator unit 6 itself.

Abstract

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.

Abstract

Electric energy cannot be kept in big scale hence this energy must always available at the time of required. As a result arises problem in facing requirement of erratic electricity from time to time, how operating an electric power system the always can fulfill request of energy power in each the time, with good grade. If energy power sent from generator far bigger than requests of energy power at payload, hence will arise problem of dissipation of energy at electrical company. While if energy power awakened sent and to be lower or doesn't fulfill requirement of consumer payload hence there will be local extinction at payload, as a result harms the side of consumer. Therefore is required adaptation between evocations with energy power request. Conditio sine qua non that is firstly must be conducted for reachs the purpose is the side of electrical company knows payload or request of electricity is future. In consequence short term payload forecast, middle and length is important task in planning and operation of power system. Intention of the research is to forecasting of payload system Bali in 5 next year causing is got requirement forecast number of electric power appropriate, with method that is simple.

Abstract

Bangli Regency is administratively located in Bali Province. The area of Bangli Regency is divided into 4 Subdistricts and 72 Villages: Susut, Bangli, Tembuku and Kintamani Subdistricts. Kintamani Subdistrict is one of the areas that has a high threat of landslides. Settlements that are still located in high risk landslide areas endanger occupants. Settlement landscape planning based on landslide mitigation needs to be done to prevent losses and casualties due to landslides. This study aims to identify legal aspects, physical, biophysical and social aspects in Kintamani Subdistrict, identify the threat of landslides in Kintamani District, and develop settlement landscape planning based on landslide mitigation in Kintamani District.The research method used refers to a modified planning process ranging from inventory, analysis, synthesis, and planning. The analysis carried out is land suitability analysis for settlement development with reference to the threat of landslide hazard. The mitigation concept is used for settlement planning which is further developed into spatial plans, activities, evacuation, facilities, facilities and infrastructure, circulation and vegetation plans.Settlement landscape planning based on landslide mitigation needs to be done to prevent the occurrence of losses and casualties if landslides also prevent the population from the threat of landslides through appropriate settlement zoning and not in the area of high-scale landslide threat.

Abstract

Bali is one of the provinces in central Indonesia that is famous for the comfort of its area. Of course this must be supported by adequate infrastructure such as drainage. With the increasing number of residents in each area such as in Jembrana Regency and inadequate drainage facilities, causing floods that disrupt the comfort of the area, drainage planning, especially secondary and tertiary channels, is necessary. in urban areas. Therefore the drainage planning there is adjusted to the planning standards that have been set and planned with dimensions using a return period (5 years) for secondary or tertiary channels. The purpose of the Final Project is to find out the plans for the environmental drainage system and analyze the dimensions of the channel drainage that can overcome inundation in the East Loloan area, Jembrana Regency. Data used are rainfall data from 2007-2016, using the RAPS method, Thiesson Polygon, type III log pearson, Smirnov-Kolmogrov, Talbot and Rational methods, the method used until you get a plan debit with an average of 0.3275 m3 / sec. Continuing to calculate the dimensional recommendations with a hydraulics count using the principle of uniform flow. From the existing conditions in the East Loloan area, Jembrana Regency often experiences inundation because of the inadequate channel dimensions, therefore it is necessary to do a re-planning with dimensions that can accommodate a larger water discharge so that inundation does not occur as before with a count of planned new plans.

Abstract

Congestion at the Tugu Ngurah Rai Roundabout junction that connects the road from Denpasar to the Nusa Dua and surrounding areas has become a problem in the city of Badung. This is because the road has not been able to handle the volume of vehicles at the intersection. Therefore it is necessary to make an underpass. The pass is planned with a total length of 408.4 meters which is divided into two parts, namely the closed section 100.40 meters and open 308 meters. The width of the road to be excavated is 16 meters wide for 2 (two) lanes. Geotechnical analysis is very necessary to plan the underpass structure, because the load that works on the underpass does not only come from traffic loads, but mostly comes from land which greatly affects structural stability. The method used for structural stability analysis in this study is the approach method based on IRC78 / 1983. The abutment design phase, like the structure of a retaining wall basically uses a trial system, then analyzes its stability provided that it must meet the value of the safety factor Sliding FS> 1.5, Bolster FS> 1.5, FS DDT> 3. In the case of the Underpass Simpang Tugu Ngurah Rai bridge the abutment is planned to be 7.8 meters high, 3.5 meters wide and 16 meters long from the ground surface. The results of the stability analysis on the abutment state that the soil can withstand shear forces, and rolling which works on the structure, but the carrying capacity of the soil cannot carry the structure above it, so the foundation below is needed. The foundation analyzed is a caissons foundation of 6 pile drill foundation with a diameter of 0.8 m and a depth of 3.4 meters. Each foundation pole can bear axial loads of 267,097 tons, so the total axial load that can be borne is 1602.55 tons. The caissons foundation with a diameter of 0.8 meters is a foundation that can withstand building structural loads on the Underpass and abutment bridges.

Abstract

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

Perkembangan teknologi rekayasa dan analisis struktur bangunan sipil saat ini sedang berkembang pesat, termasuk bidang desain struktur di dunia konstruksi gedung. Selama ini material bangunan yang digunakan dalam bidang konstruksi khususnya bangunan gedung masih rata-rata menggunakan bahan dari kayu dan beton. Namun seiring dengan berkembangnya tuntutan kebutuhan, waktu dan ilmu pengetahuan mulai menggunakan material baja. Penggunakan material baja dapat mengurangi limbah konstruksi yang selama ini menjadi masalah bagi lingkungan. Semakin berkembangnya pengetahuan dalam bidang konstruksi maka terciptalah berbagai metode dalam mendesain struktur salah satu diantarnya adalah sistem struktur komposit yang terdiri dari gabungan antara beton dan baja. Perencanaan Gedung C Universitas Pendidikan Nasional menggunakan bahan komposit pada bagian kolom dengan menggunakan metode ASD. Bangunan ini terdiri dari 5 lantai denan luas bangunan 40x19 m2, Berdiri pada kondisi tanah sedang. Analisa struktur penelitian ini menggunakan bantuan program SAP 2000 V14, sedangkan dalam perhitungan elemen struktur dilakukan secara manual dengan metode LRFD yang berpedoman kepada SNI-03-1729-2002. Hasil analisis pada penilitian ini diperoleh bahwa metode LRFD memberikan kontribusi kekakuan yang lebih tinggi pada kolom dan berakibat penggunaan profil balok yang lebih efektif (kecil) yaitu WF 298x201x14x9 dibandingkan dengan besar profil balok metode ASD yaitu WF 400x200x13x22. Reaksi perletakan struktur gaya aksial menggunakan metode LRFD lebih efektif sebesar 5% dari total rata-rata gaya aksial ASD dan LRFD. Namun metode LRFD membutuhkan kolom dengan tegangan efektif momen yang lebih besar dibanding metode ASD.
