Abstract

The implementation of the First Pillar STBM Program in Sagulung District, Batam City, which began in 2018 as a whole, has not been carried out optimally with results that are still far from the SDGs 2030 target and the Circular (SE) of the Governor of Riau Islands No. 0168/106 / SET regarding the 2019 universal access target for sanitation. The purpose of this study was to analyze the Open Defecation Free (ODF) status on land availability and economic level status in Sagulung District, Batam City. This research is an observational study with a quantitative method with a cross-sectional design. The research was conducted in Sagulung District from April to May 2020, the research sample was determined by random sampling technique, namely as many as 90 samples. The results showed that of the 6 Village in Sagulung District, there were 3 Village that had been ODF verified and 3 Village had not been ODF verified, with the status of having land to build latrines were 25 samples (27.8%) and did not have land to build latrines and septic tanks were as many as 65 samples (72.2%) with a p-vlaue is = 0.585 while the economic level with good status was 58 samples (64.4%) and bad was 32 samples (35.6%) p-value = 0.274. From the results of this study it can be concluded that there is no relationship between land availability and economic status for ODF status in Sagulung District, Batam City. It is hoped that the Batam City Health Office can advocate for the local government to build more communal latrines in Sagulung District and turn coastal areas into tourist areas so that people are ashamed of open defecation and the need to mobilize figures to implement policies or written regulations agreed upon by the local community to encourage so that people do not defecate anywhere anymore.

Abstract

Predicting stock prices is a challenging yet crucial task in financial markets. This research aims to compare the performance of two Long Short-Term Memory (LSTM) neural network models for forecasting the closing price of Nokia Corporation (NOK) stock: a univariate model using only historical closing prices and a multivariate model incorporating open, high, low, close, and volume (OHLCV) data. Utilizing historical daily data from 2015 to 2025, both models were trained to predict the next day's price based on the previous 60 days. The models' accuracy was rigorously evaluated using three key metrics: Mean Absolute Error (MAE), Root Mean Square Error (RMSE), and Mean Absolute Percentage Error (MAPE). The findings revealed a decisive outcome. The univariate LSTM model consistently outperformed its multivariate counterpart across all evaluation metrics. It achieved an MAE of 0.0591, an RMSE of 0.0887, and a MAPE of 1.39%, while the multivariate model recorded higher values of 0.0623, 0.0934, and 1.45%, respectively. This study concludes that for NOK stock prediction, a simpler model with fewer features proved to be more effective. The additional data points in the multivariate model did not enhance predictive accuracy and may have introduced noise, suggesting that the historical pattern of closing prices alone is a more powerful predictor for this particular asset.

Abstract

The post-COVID-19 pandemic period has marked an acceleration in the adoption of digital education through distance and hybrid learning policies. However, this acceleration has also revealed persistent inequalities in access to digital education across socioeconomic groups. This article analyzes the role of public policy in shaping inequalities in access to digital education in the post-pandemic period. The study examines empirical evidence from international and comparative literature on digital education policies, the gap in technology access, and their implications for educational equity. The analysis shows that policies focused on expanding digital platforms without supporting infrastructure, digital literacy, and protecting vulnerable groups tend to reinforce educational exclusion. Low-income households, areas with limited connectivity, and educational institutions with low fiscal capacity face multiple barriers to accessing quality digital learning. This article emphasizes that post-pandemic public policy needs to shift from an emergency approach to structural policies oriented toward equitable access and quality. Integration of education, telecommunications, and social protection policies is a prerequisite for sustainably reducing inequalities in digital education.

Abstract

Student assessment at the Nahdlatul Ulama University of West Sumatra is currently still manual, so a lot of time and energy is needed to do this task. the purpose of this thesis is to develop a computerized student assessment information system. in processing data and information will succeed with better changes to the existing system. The Student Assessment Information System is the one whose handling is in accordance with the courses taught by the students. processing of this value includes semester exams conducted by students. this website also contains data collection needed for value processing, namely data collection for students, lecturers, majors, courses, and classes. In addition, as a web-based and online system, this system can be accessed anytime and online using internet access. So that the information submitted is not limited by region and time. This website was developed using the PHP (Personal Home Page) programming language and MySQL database that can be used in various computer operating systems.

Abstract

Progress in various fields of technology, especially advances in information technology and computers, encouraging the emergence of new innovations in the presentation of information to meet the needs of information. As a tool of man, the computer also has advantages such as speed, accuracy and efficiency of data processing as compared to manual systems. In the case of SMAN 1 Matur still many systems are still done manually, including the majors interests of students, where the weaknesses of the current system is the amount of use of paper for printing questionnaires charging interest and talent for each student. Long process of distribution of questionnaires from teachers to students, after students filled in questionnaires, the questionnaire must be returned to the teacher to be processed in order to get the interest and talent, only then accepted by the students. Thus it will be in designing a new system of student data processing system before using the questionnaire into a web-based application that can encapsulate student data thus simplifying the decision granting the interest and talent of students of SMAN 1 mature.

Abstract

Pesticides are very useful in many areas of human activities, especially in agriculture to ensure food availability. However, pesticides also have a negative impact on the environment and health. Pesticides are classified as endocrine disrupting chemicals (EDCs), which are chemicals that can interfere with the metabolic system, binding and eliminating hormones in the body, one of which is the danger of carcinogenicity. The concentration hazard present in Pesticide was experiment to decrease the concentration by using rice husk absorbent powder. This research is an experimental research that aims to reduce the concentration of pyridaben compounds contained in pesticides by using rice husk absorbent powder. By varying the sample treatment, variations of optimum concentrations of 10, 20, 30, 40 and 50 mg/L, contact time of 12 hours, 24 hours, 2 days, 4 days and 7 days, and weight of rice husk powder 25, 50, 100, 150, 200 mg. Analysis performed on pesticides is the content of pyridaben in pestisida samite 135EC. From this research, the best result was obtained at concentration 30 mg/L with 29,74% absorption efficiency, 24 hours contact time with 92,36% absorption efficiency, and 150 mg of rice husk powder with 54,88% absorption efficiency. This condition indicates that rice husk powders are effectively used to decrease the concentration of pyridaben compounds because of their effectiveness above 50%.
