Populasi Vespa dengan mesin 2 tak, alias Vespa lawas masih banyak berseliweran dan sangat mudah dijumpai. Banyak pengguna sepeda motor vespa klasik yang tak paham mengenai perbaikan kendaraan sehingga, butuh mekanik atau bengkel jika kendaraan mereka mengalami masalah ataupun kerusakan.   Apabila   kendaraan   motor   mereka   mengalami kerusakan maka perlu dibawa ke bengkel untuk diperbaiki oleh ahlinya. Namun masih adanya kendala yang dialami mekanik yaitu harus mencari tahu apa permasalahannya, dikarenakan banyak mekanik atau teknisi baru yang belum paham tentang kerusakan-kerusakan motor vespa tersebut. Pada penelitian ini penulis membuat sistem pakar berbasis web untuk mendiagnosis kerusakan pada motor vespa klasik. Metode penelitian menggunakan forward chaining untuk mengukur suatu fakta berdasarkan gejala-gelaja kerusakan pada motor vespa klasik. Pada sistem ini diinput tujuh jenis kerusakan dan masing-masing kerusakan memiliki minimal empat gejala kerusakan sebagai basis pengetahuan ahli. Adapun proses analisis kerusakan digunakan metode forward chaining dan penentuan kerusakannya. Dengan adanya aplikasi sistem pakar ini, dapat memudahkan pemilik motor untuk mengetahui gejala kerusakan motornya, dan untuk montir atau mekanik pemula dapat memudahkan menganalisa/memperbaiki kerusakan motor vespa klasik.    Vespa is a legendary scooter that is timeless. The population of Vespas with 2 stroke engines, aka old Vespas, is still a lot around and very easy to find. Many Users of classic Vespa motorbikes do not understand vehicle repair, so they need a mechanic/workshop if their vehicle is damaged. And if their motor vehicle is damaged, it needs to be taken to a garage to be repaired by an expert. However, there are still obstacles where mechanics have to find out what the problem is, because many new mechanics or technicians don't understand about the damage to the Vespa motorbike. In this study, the authors created a web-based expert system to diagnose damage to classic Vespa motors. The research method uses forward chaining to measure a fact based on the symptoms of damage to the classic Vespa motor. In this system, seven types of damage are input and each damage has at least four damage symptoms as an expert knowledge base. The damage analysis process uses the forward chaining method and determines the damage. With this expert system application, it can make it easier for motorbike owners to find out symptoms of motorbike damage, and for beginner mechanics or mechanics it can make it easier to analyze/repair damage to classic Vespa motorbikes.","PeriodicalId":292481,"journal":{"name":"Jambura Journal of Electrical and Electronics Engineering","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122537871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hal ini terjadi akibat pertumbuhan beban yang tidak merata sehingga menyebabkan ketimpangan antara masing – masing fasa. Persentase ketidakseimbangan beban ini berpengaruh terhadap besarnya nilai arus yang mengalir pada penghantar netral. Sehingga netral tersebut dapat menyebabkan rugi  - rugi daya pada transformator distribusi. Penelitian ini yang dilakukan pada penyulang plumbungan diantaranya transformator distribusi RB877 memiliki persentase 64,1% dan RB876 memiliki persentase 21% terhadap ketidakseimbangan beban. Sehingga persentase tersebut diluar batas yang telah ditetapkan oleh standar. Dalam hal ini, penelitian dilakukan dalam rangka meperbaiki rugi – rugi daya yang timbul pada transformator distribusi RB877 sebesar 0,214 kW dan RB876 sebesar 0,025 kW dengan melakukan penyeimbangan beban terhadap masing – masing fasa. Simulasi Aliran Daya Tak Seimbang pada ETAP 19.0 digunakan dalam menyelesaikan masalah dalam penelitian ini. Berdasarkan hasil simulasi, persentase ketidakseimbangan beban transfomator distribusi RB877 menjadi 1,16% dan RB 876 menjadi 4,2%. Penyeimbangan yang dilakukan dengan membagi ketimpangan yang terjadi pada fasa yang memiliki kapasitas lebih besar ke yang lebih kecil mengakibatkan penurunan pada arus netral yang semula pada transformator distribusi RB877 sebesar 25,05 A menjadi 1,8 A dan pada RB876 yang semula 8,77 A menjadi 0,8 A. Dengan begitu, rugi daya yang timbul pada akan menurun yaitu transformator distribusi RB877 sebesar 0,00021 kW dan RB876 sebesar 0,0011 kW.The limit of load imbalance in the Electric Power Distribution System is set between 5%-20% of the load per phase. This occurs due to uneven load growth that causes inequality between each phase. The percentage of load imbalance affects the value of the current flowing in the neutral conductor. So that the neutral  will cause power loss in the distribution transformer. This research was conducted on the plumbungan extension, including the RB877 distribution transformer which has a percentage of 64.1% and RB876 has a percentage of 21% of the load imbalance. So that the percentage is outside the limit set by the standard. In this case, research was conducted in order to improve the power losses arising in the RB877 distribution transformer of 0.214 kW and RB876 of 0.025 kW by balancing theload on each phase. Unbalanced Load Flow Simulation in ETAP 19.0 is used in solving the problems in this study. Based on the simulation results, the percentage of load imbalance of distribution transfomator RB877 becomes 1.16% and RB 876 becomes 4.2%. Balancing carried out by dividing the imbalance that occurs in the phase that has a larger capacity to the smaller one results in a decrease in the neutral current which was originally in the RB877 distribution transformer of 25.05 A to 1.8 A and in RB876 which was originally 8.77 A to 0.8 A.

Penelitian dampak gangguan beban lebih terhadap Overload Shedding pada gardu induk 150kV Sukolilo ini menggunakan metode aliran daya dan kontingensi menggunakan ETAP 19.0. Terdapat 3 kondisi  simulasi kontingensi yang dilakukan, yaitu 1 kondisi penghantar mengalami trip dan 2 kondisi transformator mengalami trip. Simulasi gangguan beban lebih yang terjadi pada kontingensi ke 1 hingga 3 mengakibatkan dampak pada sistem yang menyebabkan overload shedding harus bekerja. Pada kontingensi 1 dan 3 menyebabkan overload shedding tahap 1 bekerja sehingga memadamkan beban sebesar 18,7 MW, namun pada kontingensi ke 2 menyebakan hingga overload shedding tahap 2 memadamkan total beban sebesar 54,5 MW.

Transformer loading of 150kV Sukolilo substation has exceeded 50%, thus if a fault occurs in one of the transformers it will make the loading of other transformers increase. This research on the impact of overload faults on Overload Shedding at the 150kV Sukolilo substation uses the power flow and contingency method using ETAP 19.0. There are 3 contingency simulation conditions carried out, namely 1 condition of the conductor experiencing a trip and 2 conditions of the transformer experiencing a trip. Simulation of overload faults that occur in contingencies 1 to 3 results in an impact on the system that causes overload shedding to work. In contingency 1 and 3 caused overload shedding stage 1 to work so that it extinguished a load of 18.7 MW, but in contingency 2 caused overload shedding stage 2 to extinguish a total load of 54.5 MW. The stages of load shedding at the 150kV Sukolilo substation are in accordance with IEEE Std C37 106-2003 standards, namely the maximum load shedding in the first stage is 10% equivalent to 38.56 MW and the second stage is 15% equivalent to 57 MW. The results of this overload shedding simulation can reduce the risk of continuous blackouts.","PeriodicalId":292481,"journal":{"name":"Jambura Journal of Electrical and Electronics Engineering","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133592937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
