Abstract

Purpose – Crude Palm Oil (CPO) production fluctuates with Fresh Fruit Bunches (FFB) supply and operational conditions, making production planning difficult for palm oil mills. This study develops a CPO production prediction information system that integrates a simple linear regression model into a Progressive Web Application (PWA) to provide an accessible decision-support tool. Methods – The study used 39 monthly production records from PTPN IV Regional II Adolina Palm Oil Mill, covering January 2023 to March 2026. FFB was used as the independent variable and CPO production as the dependent variable. The model was developed using simple linear regression, evaluated through an 80/20 train-test split, MAE, RMSE, and R², and implemented in a PWA-based system using PHP and MySQL. Findings – The regression model produced the equation Y = -101.869 + 0.238X. The model achieved R² = 0.872, MAE = 279.80 tons, and RMSE = 335.72 tons. With average monthly CPO production of 2,000–3,000 tons, the MAE represents an approximate error rate of 10–14%, indicating moderate predictive performance. Research implications – The findings are useful for preliminary production planning, but generalization is limited by the use of one predictor, 39 observations, one palm oil mill, and the absence of k-fold cross-validation. Originality – This study contributes by combining an interpretable linear regression model with a PWA-based system for real-time CPO prediction and visualization.

Abstract

Smoking is responsible for a high proportion of morbidity and mortality in Indonesia. Because of the loss in terms of health and economy, the smoking cessation program is the main treatment option for smokers. The information-motivation-behavioral skill (IMB) explains that knowledge is not the only determinant of behavior change, but also the motivation and behavioral skills of individuals. The purpose of the study was to develop a health education strategy by exploring the conditions of knowledge that could affect motivation to quit smoking. This research employed interpretive phenomenological analysis (IPA) on male young active smokers as students in Surabaya, East Java, from April to July 2021. The collection of samples employed snowball and purposive sampling, utilizing the in-depth interview method until data saturation was achieved. The data analysis process involved coding and verbatim transcription of the interview results, which described the interview process and provided research reflection on the interview results (self-reflection). The study was conducted on 23 students. Most respondents fell within the 20–23-year age range. On the topic of the dangers of cigarettes, they showed they only knew that they were dangerous, but didn't know to what extent nicotine and tar were hazardous to health. On the dangers of smoking to health topic, respondents knew the impact of tobacco on health, but didn't care about the effects on health. In conclusion, the level of knowledge related to smoking cessation can inform therapeutic options tailored to individual conditions.

Abstract

Competition in the business world, especially in the pharmacy industry, requires developers to find a strategy that can increase sales of special drug sales by maximizing service to consumers. One way is to keep the availability of various types of drugs in the pharmacy warehouse. To find out what medicines are purchased by consumers, it can be done using basket analysis techniques, namely analysis of consumer buying habits. Detection of drugs that are often bought together is called the association rule. Medication is an important factor whose availability must be controlled properly in a hospital. The availability of drugs at the hospital will support hospital performance. One of the data mining methods that can be used from the above analysis is the clustering method, which is grouping data items into small groups so that each group has an essential equation. The evaluation results from this study are grouping drug data with clustering techniques to facilitate the process of grouping drugs based on drugs that are often used in a certain period of time

Abstract

Terms or tokens are the main component in information retrieval system. The use of them as index andquery affects the performance of the system. This research is conducted to observe how similarity thesaurusimproves the performance of the Indonesian information retrieval system through query expansion. By using 30sets of query and 1.000 documents, series of tests are conducted using different weight of terms in query tomeasure the performance of the system before and after query expansion. By using cosine as similaritymeasurement and the weight of the query terms, the terms used in query expansion can be determined. Twotreatments that were used are by taking 5 (TH5) and 10 (TH10) terms that has the biggest similarity value withthe query. It is found that overall the query expansion improve the performance of the system compared to theone without query expansion (NoTH). However, it also depends on the weight of the terms in the query. On threeexperiment combined with NoTH, TH5, and TH10, the results show that idf is proved to be better used as weightof the terms in query in order to improve the performance of the system, either using query expansion or withoutquery expansion.
