Abstract

Many credit card issuing companies experience problems related to bill payments by their customers or also known as bad credit payments that are not according to the agreement so that they are detrimental to the company itself. In this case, there is still a pile of unclassified credit cardholder customer data and problem-solving patterns are found. The C4.5 algorithm is used to predict whether a customer is a credit default payment or not. This study uses a data set that has determining criteria, namely the amount of credit, status, age, and payment status for 1-3 months. From the results of research using 4199 customer data results in an evaluation that the C4.5 algorithm is applied accurately to predict whether or not customer credit card payments are bad with an accuracy level of 70.93%.

Abstract

Power consumption of PLN customers from household sector is quite large. It comes from the use of household appliances, such as refrigerators, televisions, dispensers, lights and air conditioners. The customers assume that their electricity usage is wasteful, but unfortunately it couldn’t be known in detail which household electrical appliances spend the most electricity. So that, difficult for the customers to monitor the power usage of each household electrical equipments. Regarding to this issue, this research focused on making a prototype of a household electrical power usage monitoring system. This system can be used by PLN customers of households sector to find out which household appliances use large power, so that the customers can manage the use of household appliances. In implementing that monitoring, it needs a capable wattmeter devices to measure the power usage of household electronic equipments The results of this measurement electric current, voltage, and power data measured through sensors. Those measurement data is sent to the database server system monitoring through the internet of things (IoT) device so that monitoring can be done through the system in a real time. This study produced a prototype of household electronic equipments power usage monitoring system based on IoT.

Abstract

Sektor rumah tangga menyumbang persentase terbesar dari total konsumsi listrik Indonesia pada tahun 2019. Pengguna di sektor ini tidak mengetahui secara detail peralatan rumah tangga mana yang paling banyak mengkonsumsi listrik. Penelitian ini bertujuan untuk menghasilkan sistem kontrol dan monitoring peralatan listrik rumah tangga dengan paradigma internet of things. Proses pemantauan dan pengendalian dilakukan untuk mendukung beberapa perangkat rumah tangga. Pada penelitian ini metode yang digunakan untuk membuat prototype alat dengan beberapa tahapan yaitu pembuatan prototype alat, pengumpulan data, dan pembuatan aplikasi mobile. Bagian utama dari perangkat prototipe terdiri dari mikrokontroler NodeMCU, sensor PZEM004T, dan relay. Hasil pembacaan sensor berupa data arus, tegangan, dan daya listrik yang kemudian dikirim dan disimpan dalam database. Setelah itu, data listrik dapat ditampilkan pada aplikasi mobile. Selain itu, juga dapat mengontrol on/off perangkat. Hasil dari penelitian ini adalah prototype perangkat dan aplikasi mobile yang dapat mengontrol dan memonitoring listrik untuk peralatan kelistrikan di rumah. Konsumsi listrik setiap alat listrik rumah tangga dapat dipantau dalam kilowatt-hour (KWH), sehingga pengguna dapat menggunakannya untuk menilai konsumsi listrik rutin peralatan listrik rumah tangga mereka.

Abstract

The need for information is very high in the current 4.0 era, every organization needs fast, accurate and detailed information. Currently there is documentation at the Indonesian Medical Council Secretariat regarding knowledge on how to handle employee problems which can help the employee's own performance so that it has an impact on secretariat activities that feel ineffective. Based on the results of the analysis that has been carried out, there is a lot of important knowledge at the Indonesian Medical Council Secretariat whose function is to support activities in Health Institutions. The methodology used in this research is to use Beccera Fernandez which was developed by Beccera and Sabherwal. The data collection methods used were observation, interviews, literature study, while the Knowledge Management System implementation used the Knowledge Management Process, and the KMS design used the Unified Modeling Language (UML) modeling. The programming languages used in building the system are PHP and MySQL. The concept of knowledge sharing among employees was applied as a result of a study conducted at the Indonesian Medical Council Secretariat. This is implemented on the website so that individual employee knowledge is not simply lost.
