Abstract

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.

Abstract

Gisella Farma Pharmacy is a pharmacy that sells a wide variety of medicines. Each type of drug has a different priority level, which causes difficulty in determining priorities for drug procurement. This can lead to a waste of funds and stock buildup, which can be detrimental to the pharmacy. Additionally, in managing drug inventory, regular checks are still required for every request, as there is no real-time information on the amount of drug stock available in the pharmacy. The activity-based costing method is used to assign different priorities to each group of drugs and support drug procurement. Extreme Programming was used in developing this system, with black-box testing as the system testing method. From the results of research using the activity-based costing method: Drug sales data in April showed that 37 items (47.44%) of drugs belonged to class A with a total sales value of 79.54%, 23 items to class B (29.49%) with a total sales value of 15.28%, and 18 items to class C (23.08%) with a total sales value of 5.18%. Drug sales data in May included 31 items (43.06%) of drugs belonging to class A with a total sales value of 79.42%, 21 items to class B (29.17%) with a total sales value of 15.18%, and 20 items to class C (27.78%) with a total sales value of 5.40%. Drug sales data in June showed that 39 items (49.86%) of drugs belonged to class A with a total sales value of 79.42%, 27 items to class B (29.67%) with a total sales value of 15.37%, and 25 items to class C (27.47%) with a total sales value of 5.21%. Drug sales data in July included 40 items (44.94%) of drugs belonging to class A with a total sales value of 79.74%, 24 items to class B (26.97%) with a total sales value of 14.96%, and 25 items to class C (28.09%) with a total sales value of 5.30%.

Abstract

The Selayar Islands Regency Education and Culture Office does not currently have a website to monitor school inventory data. This research aims to create a Information System that will help monitor school inventory under the supervision of the The Selayar Islands Regency Education and Culture Office. The research follows the waterfall method and uses experimental research with data collection through observation, interviews, and documentation. The application is tested using the black box testing method. The result is a school inventory monitoring application, and an evaluation conducted through questionnaires with 120 respondents shows a satisfaction rate of 82.26% for this application. It can be concluded that users are pleased with information system, and it is effective for monitoring school inventory at the Selayar Islands Regency Education and Culture Office.

Abstract

The management of research and community service data of lecturers in higher education institutions requires an integrated system to support effective monitoring and reporting processes. At UIN Alauddin Makassar, research and community service data had previously been stored separately in Microsoft Excel files managed by different staff members, which made data processing, retrieval, and comprehensive analysis difficult. This study employed a quantitative approach with stages consisting of requirements analysis, system design, data warehouse implementation, and system testing. Data integration was carried out through the Extract, Transform, and Load process into a structured centralized data storage. System testing was conducted using the Black Box Testing method to ensure that all system functions operated according to user requirements. The results showed that the implementation of the data warehouse successfully integrated research and community service data in a structured manner, reduced data duplication, and improved efficiency in data retrieval and report generation. The developed system also provided monitoring reports in the form of a web-based dashboard that was informative and easy to understand. Therefore, the implementation of this data warehouse was able to assist the Institute for Research and Community Service (LP2M) in managing and monitoring lecturers’ research and community service activities more effectively and optimally.

Abstract

One indicator of the quality of an information system is the speed of data processing. A database's most common data processing operations are adding, displaying, changing, and deleting data. The amount of data stored in the database significantly impacts the performance of data processing and, therefore, the performance of information systems. The update command changes some or all of the data in a table. The update command works by retrieving the data in the table to be changed, entering the new data in a form, and then sending it back to the database. The update command is often combined with a condition specifying which data rows must be changed. This research is an experimental study that compares the use of the update command with a stored procedure to the use of the update command without a stored procedure. The results showed that the average processing time for the update command with the stored procedure was 348.896 milliseconds for the minimum data category, 266.462 milliseconds for the medium data category, and 279.543 milliseconds for the maximum data category. The average processing time for the update command without a stored procedure was 297.132 milliseconds for the minimum data category, 747.670 milliseconds for the medium data category, and 1256.273 milliseconds for the maximum data category. These results suggest that the update command with a stored procedure is more efficient than the one without a stored procedure. This is because the stored procedure can pre-compile the SQL statement, which reduces the time it takes to execute the statement.
