Abstract

Shallot is a tuber plant commonly consumed by Indonesian people. Shallot is one of the three Allium members who are popular and have high economic value. In the cultivation process, shallots are vulnerable to pests and diseases. Some pests and diseases that can attack onion plants, namely: lalat penggorok daun, ulat bawang, trips, ulat tanah, layu fusarium, bercak ungu, antraknosa, virus mozaik bawang, bercak daun. Usually when the onion plants are attacked by pests or diseases, farmers directly provide pesticides or treatments which sometimes do not match the pests and diseases that attack. As a result, handling that is not optimal can even lead to new pests or diseases. The purpose of this study is to help farmers detect early symptoms of shallot pests and diseases so that the handling of pest and disease attacks is carried out more directed and maximally. The data processed is 10 data attacks using the Dempster Shafer method. This method processes data in the form of symptoms that produce a diagnosis in the form of shallot pests and diseases and handling steps with an accuracy rate of 95%. So this method is suitable for use in the diagnosis of shallots pests and disease. Keywords: Expert System, Dempster Shafer, Diagnosis, Shallot Pests and Disease.

Abstract

E-government services or systems aim to improve the quality of services, enabling time and effort savings in government administration. The use of e-government services is not limited to the millennials, but also the people who were laymen of a system. Besides, millennials who sometimes still use information from parents or others who have used the previous system can use the information to miss the benefits of the system that has been done online so that the effort to use the system is low. This research is about online marriage registration services on the Simkah web application owned by the Ministry of Religion of the Republic of Indonesia because there are still many prospective brides or people who have not used the online service. The model used is to combine the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model and the modified IS DeLone and McLean (D&M) success model and consider moderating age, gender, and internet experience. In this study, it is necessary to know whether the constructor factors in the UTAUT2 model and the D&M model influence the intention to use online marriage registration services. The study was conducted in Sleman Regency. The construct finding that affects the intention to use online marriage registration services is hedonic motivation so the Ministry of Religion needs to increase hedonic motivation or mean it as an impulse in someone to use something.

Abstract

The length of the queue at a service provider counter certainly makes the service users uncomfortable, bored, and even tired while waiting. In addition, too much time is wasted while waiting in line. The uncertainty of time in waiting their turn often causes problems for service users which often results in no service to some users because the service hours are over. This also happened to several administrative services at Universitas Teknologi Yogyakarta, where students had to queue long at bank counters on campus or in the Finance Department counters just to pay tuition fees or validate payments. Therefore, in this article, we discuss the development of Android-based applications that serve to assist service providers in managing queues, as well as making it easier for queues to retrieve queue numbers and get an estimated time to wait their turn to get service. The application was developed using Android Studio by utilizing Google's Firebase database to support the ease of application development. To measure the appropriateness of application use, tests on several different devices have also been carried out.
