Analisis User Interface Pada Aplikasi Potio Dengan Metode Heuristic Evaluation

2026-06-22T14:37:29+08:00

Potio is a mobile-based reminder application that can help its users to take vitamins or medicines consistently. This study aims to analyze the User Interface of the Potio application, because the application UI design is limited only by the developer, without involving the application users. The analysis was conducted to determine whether improvements are necessary or not. In this case, the need for improvements is determined from the results of the calculation of questionnaire data for each Heuristic Evaluation principle that has been submitted to expert respondents. From the calculation results using the Severity Rating formula, there are two principles that have a fairly high average Severity Rating value, namely the Help Users Recognize and Recover from Errors principle and the Help and Documentation principle. This second principle has a rounded value of 1, where a value of 1 means that improvements are not really necessary because the problems found do not affect user comfort.

Pengujian White Box Basis Path Testing Fitur Menghitung Aplikasi ComfyLearn

2026-06-22T14:37:30+08:00

This research aims to test the learning features in the ComfyLearn application using the white box testing method with the basis path technique. ComfyLearn is an Android-based educational application aimed at young children in learning while playing. To ensure the quality and reliability of applications, systematic software testing is required. This research applies the white box testing method with the basis path testing technique to test the program code for the learning counting feature, because this method is able to evaluate the program logic as a whole. This technique includes making flowcharts, flowgraphs, graph matrices, calculating cyclomatic complexity, determining independent paths, and preparing test cases. Based on the calculation results, it shows that the counting feature has a cyclomatic complexity value of 5, including the low category. This means that the complexity of the program logic is not too high so there is relatively little potential for errors to be found. There are 5 independent paths that need to be tested. Testing is carried out through unit testing and manual testing to verify whether the learning process has run as expected. The test results show that the program code in the learning counting feature functions well and meets expectations after making improvements. Thus, it can be concluded that the code structure in this feature section is quite reliable and can be used as a basis for further development.

This research aims to develop a web-based expert system designed to assist in troubleshooting computer hardware issues at the STMIK Kharisma Makassar Laboratory. The system employs a forward chaining method to diagnose problems based on symptoms reported by users. The research methodology utilized is R&D with a descriptive and quantitative approach. Test results indicate that this system can deliver accurate diagnoses and relevant solutions, thereby enhancing efficiency in addressing hardware damage issues.

Analisis Kepuasan Implementasi Bot WhatsApp Pelayanan Permohonan Surat Akademik UNU Lampung Menggunakan Metode PIECES

2026-06-22T14:37:30+08:00

Academic administration is a core service in higher education institutions that involves a high level of interaction with students, particularly in managing academic documents. Along with the increasing number of students and the demand for fast, accurate, and responsive services, Universitas Nahdlatul Ulama (UNU) Lampung developed a WhatsApp Bot for academic document request services based on Node.js without using the official WhatsApp API. However, the implementation of a non-official API-based chatbot requires a comprehensive readiness evaluation that considers not only technical aspects but also non-technical dimensions. This study aims to analyze user satisfaction and implementation readiness of the WhatsApp Bot for academic document services at UNU Lampung using the PIECES method. This research employs a descriptive quantitative approach, with data collected through observation and questionnaires. The questionnaire was designed based on the PIECES indicators, namely Performance, Information, Economics, Control, and Service, and involved 52 student respondents. The data were analyzed by calculating the average satisfaction score for each indicator. The results show that all PIECES indicators fall within the satisfied category, with average scores of 4.04 for Performance, 4.00 for Information, 4.11 for Economics, 4.08 for Control, and 3.99 for Service. The overall average satisfaction score of 4.04 indicates that the implementation of the WhatsApp Bot is satisfactory and feasible as an academic service system. The Economics indicator achieved the highest score due to significant time and cost efficiency benefits, while the Service indicator obtained the lowest score, mainly due to limitations in automated service interaction. Overall, the WhatsApp Bot improves the efficiency and effectiveness of academic document services and is suitable for further development.

Rancang Bangun Sistem Pemantauan Penggunaan Air di Perumahan Kampung Pemulung Hertasning Makassar

2026-06-22T14:37:30+08:00

Permasalahan ketersediaan air bersih selama musim kemarau menjadi tantangan utama bagi warga di Perumahan Kampung Pemulung Hertasning Makassar. Sebagai upaya mengatasi permasalahan tersebut, penelitian ini bertujuan untuk menghasilkan sistem pemantauan penggunaan air yang berfungsi untuk merekam data penggunaan air warga serta menampilkan hasil analisis data pemakaian air selama satu bulan. Berdasarkan hasil pengumpulan data, total volume air yang digunakan oleh seluruh warga dalam satu hari adalah sebesar 4.026,8 liter, dengan rata-rata penggunaan air per rumah sebesar 129 liter/hari. Analisis persentase penggunaan air menunjukkan bahwa 50% rumah menggunakan air dalam batas normal (<150 liter/hari), 45% rumah mendekati batas konsumsi boros (150–200 liter/hari), dan 5% rumah tergolong boros (>200 liter/hari). Hasil ini dapat memberikan gambaran mengenai pola penggunaan air di lingkungan tersebut, sehingga dapat menjadi dasar dalam pengelolaan sumber daya air secara optimal selama musim kemarau. Selain itu, dilakukan pengujian tingkat kegunaan sistem menggunakan SUS. Hasil pengujian menunjukkan skor SUS sistem sebesar 79,08 yang berarti bahwa sistem termasuk dalam kategori usable, yaitu sistem mudah digunakan, bermanfaat, dan dapat diterima dengan baik oleh pengguna.
