Abstract

The 20 KV PMT (Circuit Breaker) is an important equipment for the reliability of electricity distribution. Therefore it must be maintained so that it is always in good condition with regular maintenance. Prior to maintenance, PMT is terminated from the bus bar, which is called the rack out process. After maintenance, the PMT is reconnected with the bus bar, which is called the rack in process. Usually, 20 KV PMT rack in and rack out process in maintenance or disturbance is still using the manual method. The 20 KV PMT can only be racked in and racked out in one way, by turning the lever. The lever will rotate the bolt as a PMT rail. In the manual method, there is no system for monitoring the condition of the bus bar whether it is has electric-voltage or not. There is also no remote control that can rack in and rack out. So officers must ensure the conditions of PMT and bus bars are safe manually, before maintenance is carried out. This is quite troublesome and dangerous for officers. From these problems, in this research  designed a system that could ensure the condition of the PMT and the bus bar was safe before the rack in and rack out process was carried out and could monitor and control the system remotely using SCADA. Rack-in and rack-out automation system using VT SCADA, using Ethernet Shield that has been connected with Arduino Mega. Ethernet is connected to a mini PC. The microcontroller pins will be connected to the relays that will turn or stop the motor. The rack in and rack out commands from VT SCADA will determine the rotation of the motor so that the PMT moves. The current sensor reads the current flow and detects interference. Interference detection will automatically make PMT Rack out. System testing shows that the process of racking out in a state of maintenance or disturbance can be carried out automatically controlled by VT SCADA. Current sensor works to detect the current flowing, so that it can detect PMT interference and perform automatic rack out. The rack-in process is also capable of being remotely controlled with VT SCADA. This makes it easier for officers to also become additional reliability of PMT in the 20 KV cubicle.

Abstract

Di dunia medis, inkubator biasanya digunakan untuk merawat bayi yang baru lahir. Namun, fitur yang terdapat dalam sistem inkubator terbatas pada kontrol suhu, sementara untuk menunjang kondisi bayi yang baru lahir, kelembaban udara juga menjadi parameter penting. Selain itu, sistem yang dapat mendeteksi kapan bayi buang air kecil, dapat mempercepat penanganan dan perawatan bayi. Humidifier biasanya digunakan sebagai pengontrol kelembaban karena murah dan mudah dioperasikan serta mampu memberikan hasil yang baik, sistem tersebut dikombinasikan dengan sensor DHT-11 agar dapat bekerja berdasarkan perubahan kelembaban di dalam ruangan. Sedangkan untuk mendeteksi keberadaan urin, digunakan sensor YL-83 yang biasanya digunakan untuk mendeteksi air dengan perubahan tegangan output sensor. Seluruh sistem diintegrasikan dengan mikrokontroler ATMEGA 16 untuk mengontrol operasi humidifier dan menerima informasi dari detektor urin. Pada penelitian ini, kelembaban ruangan dipertahankan pada nilai 70%, dan alarm bel akan aktif ketika sensor mendeteksi keberadaan urin. Hasil pengujian menunjukkan bahwa prototipe ini dapat bekerja dengan baik sesuai dengan referensi yang diinginkan.Kata kunci : bayi, detektor urin, humidifier, inkubator,kelembapan.

Abstract

An official travel assignment letter is a type of assignment letter needed by an employee in carrying out work assignments. In many ways, the assignment letter information system is built based on web-programming. In web-programming there are two methods to send data from client to server. The two methods are the POST method and the GET method. Information security is an important aspect that needs to be considered in design a information system. There are many attacker spying data on information system daily. Usually the attacker uses the loopholes in the data transmission method to attack the system. There are many techniques used to attack information systems likes WAVs (Web Application Security Scanners). WAVs is a program that is used to find security holes in web-based information systems using several methods, such as XSS, SQL Injection, Intercept and Bruteforce. One program that can be used is Burp Suite. Burp Suite is often used by security auditors, researchers, and testers for analysis of different systems. Burp's core functionality is to intercept and display HTTP requests in a structured manner. The Vocational School of Diponegoro University has developed an information system that is used to manage this assignment letter. The information system is design using a web-based application. However, the system has never been technically audited on its security level. Therefore, it is necessary to audit the information system security techniques so that the level of information system security can be ascertained and corrective steps can be taken if there are security holes found. This study is intended to conduct a technical audit of the security of the UNDIP Vocational School assignment letter information system. The audit was conducted using the WAVs (Web Application Security Scanners) method with the Burp Suite application. The results of the brutefoce test using Burpsuite showed that there was no suitable password. However, the fact that an attacker can attack 30,0006 times is a weakness that needs to be fixed.

Abstract

By implementing digitalization, organizations and companies can increase and maintain competitive advantage, because it can increase productivity, innovation and reduce costs. One of the activities carried out by organizations is data management, including organizations operating in the education sector, such as universities. In managing a university, there are various kinds of data that must be managed. Data on the number of students, number of research studies, number of services, etc. need to be managed well. The data is usually stored in several separate places. If managers need information, they have to collect the data from several sources and process it manually using software such as Microsoft Word or Microsoft Excel. This causes the process of searching for information to take a long time, because there are several stages that must be carried out before getting the information in question. In this study, we developed web-based data management information system in universities using Waterfall Software Development Lifecycle (SDLC) method. The information system that was developed passed the Black Box method test with 100% of the possible points. According to this outcome, every feature created is in line with the executed design.
