Abstract

Technological advancement in information technology applications allows the data recording process to become easier. Putra Mariyo Trading Business is a business institution that sells wood as a building material in various types and sizes. Data processing of incoming and outgoing goods in this business is performed only by writing goods data into a specific book. Consequently, some problems such as the loss of data and miss calculation in processing transactions usually occur. Therefore, in this research, we design a system to address the problems. The system is developed by following the Waterfall software development method. To build the system, we opt to use PHP programming language, CodeIgniter framework, and MySQL as the database server. To determine system reliability, this information system testing uses black box testing which focuses on the functional requirements of the system. To evaluate the performance of the system two testing steps i.e., black-box testing and System Usability Scales (SUS) are adopted. Black-box testing results show that the error percentage of our system is 0%. The SUS testing is conducted to obtain responses from users and the SUS score obtained is 70.1 indicating that the system is at the "good" level and reliable to use.

Abstract

Presently, the complaining service in Kartasura local government relies on manual recording where people must come to the government office, write their complaints and submit them to the office staff. This situation causes inefficiency since people have to travel from their places to the local government office. Moreover, the manual recording makes the complaints cannot be managed properly since the same complaints can be submitted more than one time. Additionally, it also causes some confusion to the government staff since they need to carefully check whether it has been submitted previously and approve the complaints accordingly. To solve the issue, a web-based application complaint system is developed to reduce the number of the same complaints from the citizen as well as to help staff manage the complaints data. The Jaro-Winkler String Similarity algorithm is adopted to check the similarity of newly submitted complaints with existing complaints data. The algorithm detects similarities of newly submitted complaints by determining the level of string equality to the existing complaints. Experimental results using one month period of complaints data in December 2022 show that the application is able to detect the similarity between the newly submitted complaints to the existing complaints. As the value of similarity threshold is higher, the number of rejected complaints also increases. Meanwhile, the test results of the system using the System Usability Scale Score obtained an average value of 76.5, which means the system is included in the Acceptable category and can be used for daily activity.

Abstract

Abstract–The management of posyandu data in Majegan Village is still carried out manually. This causes health monitoring to be not optimal, especially in detecting stunting in toddlers. One of the efforts to overcome this problem is to provide a posyandu information system that can make it easier for posyandu officers to record and analyze fetal growth until toddlerhood and can detect symptoms of stunting. Through the implementation of Bayes' theorem in a web-based application, stunting symptoms can be observed earlier. Bayes' theorem calculates the values of the symptoms experienced by toddlers so as to obtain the results of probability numbers that can be used to predict stunting in toddlers. System design uses the waterfall method which goes through the stages of SDLC (System Development Life Cycle). After the system was developed, to test the quality of the application and the accuracy of naïve bayes in predicting stunting, two types of testing were carried out, namely black box testing and system usability testing (SUS). The black box test results show that the application functionality runs well with an error percentage of 0%, while the SUS test results show that the application has a usability level at Level B which means the application can be used and help users. Meanwhile, the results of the prediction of naïve bayes produced the model with the highest prediction of 60%.

Abstract

Tabung gas elpiji menjadi salah satu kebutuhan primer masyarakat di Indonesia. Salah satu komponen pendukung faktor keselamatan dalam penggunaan tabung elpiji adalah karet perapat (rubber seal). Saat ini Pertamina melakukan outsourcing ke berbagai industri produksi karet untuk memenuhi kebutuhan suplai karet perapat tabung elpiji. CV Lingga Pratama sebagai salah satu industri yang menyuplai kebutuhan karet perapat masih menggunakan mesin press karet manual untuk memproduksi karet perapat tersebut. Kualitas dari karet perapat yang diproduksi menjadi sangat bergantung pada kelihaian operator dari alat press tersebut. Beberapa faktor yang berpengaruh pada kualitas karet perapat yang dibuat adalah suhu, tekanan, dan lama waktu press mesin terhadap bahan baku lembaran karet. Pada kesempatan kali ini telah dibuat suatu sistem yang terdiri dari mikrokontroler berbasis Arduino yang dapat melakukan pengukuran suhu secara contactless dengan menggunakan modul sensor suhu inframerah dan pengukuran tekanan dengan menggunakan load cell. Sistem ini dapat menampilkan nilai suhu yang terukur serta tekanan dari alat press melalui layar LCD kecil yang dapat dipantau oleh operator. Sistem juga akan memberitahukan operator melalui suara dari alarm apabila waktu yang telah ditentukan untuk melakukan proses press telah tercapai.
