E-Kuesioner Evaluasi Kualitas Layanan Akademik Universitas Timor Menggunakan Metode Prototype

Eugenius Charles Odja — 2024-10-20

In the era of sophisticated technology that brings many changes in various aspects of life, technological developments also have an impact in the field of education. Quality and quality assurance can be seen and measured from the level of student satisfaction during the lecture process and the services provided by academic staff to students. In the implementation of the distribution of academic service evaluation questionnaires at Timor University, they still use paper questionnaires that are distributed to students to be filled in. This results in inefficient time in filling out the questionnaire and requires large costs because it still uses paper media. So a system is needed to handle these problems so that the process of filling out questionnaires can be done centrally in 1 database that has been integrated with a computer system. In some previous studies, the system built in terms of features is quite complete but can only be accessed by 2 users, namely students and the person in charge of the academic section. The account list feature itself by students. So based on the description of the background explanation of the problem in the previous paragraph, a web-based application is needed to handle these problems, namely "E-Questionnaire Evaluation of Academic Service Quality (EKLA) at Timor University Using the Prototype Method". It is hoped that in the future the application built by the author will be useful in academic service activities at Timor University.

Penerapan Model Spiral dalam Pengembangan Sistem Informasi Keterbukaan Desa (SiKD) untuk Mendorong Aksesibilitas dan Akuntabilitas Pemerintahan Desa Wilayah Pegunungan

Bayu Widodo — 2024-10-20

The development of the Village Openness Information System (SiKD) aims to encourage transparency and community participation in managing village government. This research highlights the importance of using information technology in improving the performance of village governments, especially in Mekarsari Village (Sukabumi), Garumukti Village (Garut), and Bantar Kulon Village (Pekalongan). These three villages have mountainous geographical characteristics and limited transportation access, but have great potential in the agricultural sector. The research methodology uses the Spiral Model which involves the stages of problem identification, planning, risk analysis, engineering, construction and release, and user evaluation. Data collection was carried out through observation and interviews with village officials and community leaders. The research results show that the development of SiKD with the Spiral Model allows the preparation of detailed and systematic digital data, which is presented in the form of a dashboard. The SiKD dashboard facilitates measurable and sustainable village development planning, focuses on utilizing village funds according to residents' needs, and accelerates the achievement of Sustainable Development Goals (SDGs). The implementation of SiKD is expected to increase information transparency and the performance of village government services effectively and efficiently.

Fenilinas Adi Artanto — 2024-10-20

For CPNS registration in 2024, a digital stamp purchase method will be implemented via the website https://meterai-elektronik.com as a requirement for complete administration. However, the page that provides e-stamps experienced an error because many visitors entered and tried to buy e-stamps at the same time. This disruption has resulted in several people having opinions about e-stamps. To find out people's sentiments about e-stamps after this incident, sentiment analysis was carried out. In analyzing these sentiments, the Random Forest algorithm is used with the Bag of Words model, where Random Forest is a development method of Classification and Regression Trees (CART) which is said to be more precise in predicting and the Bag of Words model is widely used with good results for predicting language modeling and classification. documents because Bag of Words is simple and flexible. In sentiment analysis, 86% of neutral opinions were produced, 9% of negative opinions and 5% of positive opinions. Then the Random Forest algorithm with the Bag of Words model got an accuracy value of 70.1%, precision of 50.7%, recall of 54.1%, and F1-Score of 47.6%.

Analisis Pola Kunjungan pada Objek Wisata Kabupaten Simalungun Dengan Menggunakan Algoritma Apriori Berbasis Website

Erika Purba — 2024-10-20

Tourist attractions are places of interest and visited by tourists because they have certain appeals. These attractions can include natural tourism, cultural tourism, artificial tourism, or agro-tourism. Simalungun Regency offers various interesting tourist spots, ranging from natural beauty such as waterfalls and lakes to rich traditional cultures that reflect local history and customs. However, information about tourist visit patterns remains limited. A deeper understanding of these patterns is crucial, especially for tourism managers in designing effective and sustainable development strategies. Therefore, this study aims to identify associations or relationships between tourist attractions based on tourist visit data. The Apriori algorithm was chosen for its ability to discover high-frequency patterns in large datasets. These patterns are expected to provide valuable insights for tourism managers in designing effective promotional strategies. Apriori is a well-known algorithm in data mining, particularly for finding frequent itemsets using association rule techniques. The algorithm is carried out by determining frequent itemsets, from 1-itemset to multi-itemsets, until the association rules are derived from the pre-selected data. To obtain these frequent itemsets, each selected data must meet the minimum support and minimum confidence requirements so that the resulting association rules are relevant and practically applicable.

Tresi Aprilia — 2024-10-20

Breast cancer is one of the diseases that causes death and is one of the most frightening leading causes worldwide. This disease falls under the category of highly dangerous cancers, ranking second after lung cancer. Breast cancer cases occur in large numbers across various regions of the world, raising significant concerns globally. Breast cancer not only affects the quality of life of patients but also contributes significantly to the global cancer mortality rate. It ranks as the fifth leading cause of cancer-related deaths, accounting for approximately 16.6% of the total cancer deaths worldwide. In this study, a classification of blood sample data from breast cancer patients was conducted. Various classification techniques and methods were applied, including the K-Nearest Neighbor (KNN) method and Naïve Bayes (NB). To achieve accurate results, this study tested accuracy using Cross Validation techniques and a Confusion Matrix to evaluate the test data. Of the total 569 data points collected, 70% were used as training data, amounting to 398 data points, while the remaining 30%, or 171 data points, were used as test data. The results of this study showed that the Naïve Bayes method produced an accuracy rate of 96%, with a precision of 94% and a recall of 91%. On the other hand, the K-Nearest Neighbor method yielded a lower accuracy rate of 73%, with a precision of 74% and a recall of 66%, using K=7.

Sistem Informasi Iklim dan Kualitas Udara pada Laboratorium Kalibrasi BMKG Berbasis Website

M. Audi Ikhsan — 2024-10-20

To ensure the reliability of measurement results, the calibration laboratory of the Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG) requires accurate control of temperature and humidity. Conventional manual monitoring methods are susceptible to errors caused by human interaction and environmental fluctuations. To address this challenge, a web-based monitoring system has been developed. This system automates the measurement of temperature and humidity, thereby increasing efficiency and reducing the risk of human error. Two prototype meters have been integrated into the system, which have been proven to have an accuracy of over 90% for temperature measurements. The system is capable of measuring humidity in the range of 0% to 100% with an accuracy of ±5% and temperature in the range of -40°C to 80°C with an accuracy of ±0.1°C. By automating the monitoring process and providing real-time data access, this system makes a significant contribution to improving the reliability and efficiency of the BMKG calibration laboratory. The implementation of this system is expected to ensure the consistency of calibration measurement results, support the optimal functioning of the laboratory, and contribute to improving the quality of meteorological, climatological, and geophysical services in Indonesia.
