Abstract

Penyediaan sumber tenaga listrik memegang peranan penting dalam berbagai aspek kehidupan. Oleh sebab itu, dibutuhkan pasokan tenaga listrik yang bisa memenuhi kebutuhan secara terus menerus. Saat ini banyak pengguna mempergunakan pembangkit listrik cadangan yang disebut dengan generator set (genset). Genset sebagai pengganti apabila PLN padam, sehingga aktivitas penggunan tidak terganggu. Saat ini genset tidak hanya digunakan di industri, melainkan sudah banyak digunakan di rumah tinggal. Dalam pengoperasian sebuah genset, jarang sekali ditemukan pengontrolan genset secara otomatis. Semua pengoperasian dilakukan secara manual, mulai dari melapis switch tenaga dari sumber PLN atau pembangkit, menstarter genset, menutup switch tenaga dari genset, barulah keluar tenaga listrik dari genset dapat digunakan. Selain itu genset dapat menyebabkan polusi udara serta biaya operasional yang besar karena menggunakan bahan bakar minyak. Penelitian ini mencoba menerapkan alternatif lain sebagai cadangan tenaga listrik. Penelitian ini menerapkan prinsip penyimpanan tenaga listrik. Sistem yang dirancang tersebut dapat diaplikasikan untuk kebutuhan suplai cadangan listrik pada instalasi rumah tinggal. Sistem ini mempunyai beberapa keunggulan dibandingkan dengan genset. Diantaranya adalah biaya operasional yang rendah, perawatan system yang sederhana, serta ramah lingkungan.

Abstract

The test is one way to measure the level of student ability in participating in learning. One type of exam given to students is the type of essay exam. This research focuses on making automatic grading for essay-type tests using cosine similarity. This method has several stages such as tokenizing, filtering, stemming, analyzing, weighing words in documents with cosine similarity. The stemming process uses the Nazief & Adriani algorithm. The results of this study are concluded that the selection of words that are considered as keywords in the answer key greatly affects the results of the assessment of the system. This is evidenced by testing applying the cosine law of 89.5%. However, there are several types of questions that are significantly different because there are unique characters in the database and answer keys that do not contain keywords that match the correct answer.

Abstract

Nowadays, cancer is often heard as a topic of conversation for both men and women in Indonesia and even in the world, in addition to the symptoms that are not too significant and also the lack of public awareness to carry out periodic health checks, which has a negative impact on health. This lack of care is also caused by several factors, namely the lack of the community's economy, too busy with work (other matters) and even some people are not ready to know and accept the disease they are suffering from. Based on all the factors causing the reluctance of medical examinations, of course, it requires us to carry out examinations so that we can prevent and treat them early if they are diagnosed with certain diseases. There are several cancers with predominant sufferers and even only suffered by women, one of which is cervical cancer. In 2020 it is estimated that cases of cervical cancer will increase by 3.4% from 6.6% in 2018 to 9% and even cervical cancer will also become the third deadly disease in women after breast cancer and lung cancer. From this it can be seen that the percentage of deaths caused by cervical cancer is always increasing. Therefore, to reduce the high mortality rate, a clustering technique was carried out to group the data into their respective clusters based on the similarity of characteristics between one data and another. The algorithm used is K-Means with the rapid miner tester application. The final result obtained is that cluster 1 has more data and it is stated that out of 72 data on Cervical Cancer only 28 are declared as sufferers of Cervical Cancer and 44 other data are not.

Abstract

The function of the grounding system is to limit the voltage between equipment and the ground and neutralize the voltage that arises at the ground surface due to fault currents flowing in the ground. An unsafe grounding system can disrupt system reliability and human safety in the substation area. This research aims to simulate the design of a substation grounding system with the influence of variations in location and number of electrodes installed in grids and rods in swampy soil conditions with different soil resistivity values. The impact of these parameters is on the resistance value, touch voltage, and step voltage at a weight of 70 kg by using the CYMGRD application as a medium to see the effectiveness and optimization of whether the substation grounding system with variations in the outside area and variations in the number of electrode rods meets the requirements without exceeding safe limits on systems or humans. This grounding system design is designed for two cases, namely case 1: the maximum touch voltage and maximum step voltage values exceed the permitted touch voltage and maximum step voltage, so conditions like this are included in the criteria for being unsafe and can endanger personnel in the field. Case 2: the touch voltage and step voltage values are smaller than the permitted touch voltage and step voltage values, so this design is included in safe conditions and meets the criteria for a good and safe grounding system.

Abstract

The grounding system is one of the security systems in substations to channel excess voltage caused by lightning strikes that occur at substations, as well as electrical equipment. To design a grounding system, there are several factors that must be considered, including the type of soil, the configuration of the grounding system, the resistivity of the soil, and the condition of the surrounding environment. The aim of this research is to determine the safe limits in the substation grid grounding system which is influenced by the type of soil and influences the touch voltage and step voltage, which can be dangerous to humans. The method used is simulation with the Finite Element Method (FEM) in the ETAP application. Finite Element Method (FEM) is a method that uses image mediation by assuming that the grounding system is an equipotential structure. The test results were deliberately carried out with larger substation area parameters and different soil types, so that the differences between the influence and appearance of touch voltage and step voltage can be seen clearly.
