Customer satisfaction is a crucial indicator in assessing the quality of a company's products, services and overall experience. This research aims to identify the level of customer satisfaction and optimize the available data for effective use in sentiment analysis. In this study, we analyzed 4,353 customer reviews collected over the past year, with 3,481 reviews used as training data and 871 reviews as testing data. The analysis process was conducted using the Cross-Industry Standard Process for Data Mining (CRISP-DM) approach and leveraged the Logistic Regression algorithm to build a predictive model. Model evaluation using the confusion matrix yielded an accuracy of 94.60%, a precision of 94.26%, and a recall of 94.60%. The analysis was conducted using Jupyter Notebook and the Python programming language. The results indicate that sentiment analysis is effective in identifying and predicting customer satisfaction levels, which in turn can help a company’s products improve its service strategies. The optimization of previously underutilized data now provides deeper insights into customer perceptions and expectations, enabling the company to make more targeted decisions and enhance overall customer satisfaction.

This study aims to enhance students' learning outcomes in Natural Science (IPA) through the demonstration method in fourth-grade students at SD Inpres Teas, Noebeba District, Timor Tengah Selatan Regency. The research was motivated by low science learning outcomes, with 60% of students failing to meet the Minimum Competency Criteria (KKM) of 70. Conventional teaching methods contributed to students' passivity and lack of engagement. This Classroom Action Research (CAR) follows the Kemmis and McTaggart model, consisting of two cycles with four stages: planning, implementation, observation, and reflection. The study involved 10 fourth-grade students, with data collected through learning outcome tests, observations, and teacher interviews. Descriptive quantitative analysis compared student performance before and after intervention. Results indicated that the demonstration method effectively improved science learning outcomes. Initially, students scored an average of 73.5, with a mastery rate of 40%. After applying the demonstration method in cycle I, the average increased to 84.1, with 70% mastery. In cycle II, refining teaching strategies led to an average score of 90.1, with 90% mastery. The method also enhanced student engagement, teamwork, and conceptual understanding. These findings suggest that the demonstration method is an effective strategy for improving science learning outcomes. Teachers are encouraged to incorporate demonstrations regularly, and schools should provide necessary resources to optimize learning experiences.

Companies often face various obstacles related to managing raw material inventory to meet demand, one of which is Peuyeum Ketan Istimewa. Working in the food processing industry, of course, raw material inventory management needs to be planned optimally to avoid various risks that can harm the company. The Quantity Discount model is used to take advantage of cost savings provided by suppliers when purchases are made in large quantities, while other efforts that can help manage raw materials in a company are by knowing the safety stock and reorder point of raw materials and also forecasting demand to predict future demand. This study will use the Quantity Discount model which optimizes inventory levels by considering storage costs, ordering costs, and quantity discounts. The calculations carried out are also to find the value of the company's Safety Stock and Reorder Point. The results of this study indicate that the use of the Quantity Discount method can reduce total costs by Rp26,319,267/year, while forecasting using the seasonality method increases the accuracy of demand predictions, thus enabling more efficient inventory management. The implementation of this model is expected to provide a significant contribution to operational efficiency and cost reduction at Peuyeum Ketan Istimewa

Gold (Au) as a precious metal has played significant role throughout human history. Most gold ores subjected to leaching using the sodium cyanide (NaCN) contain high levels of base metals. High base metal content can influence the recovery of pregnant leach solution (PLS), as it affects the consumption of sodium cyanide (NaCN) and lime used to optimize the gold ore leaching process. Pre treatment leaching process is required for gold ores before the leaching process is carried out. In this study, a pre treatment leaching process was carried out using the Aachen High Shear and Filblast Low Shear Reactors with variations in feed solids percentage for each reactor, utilizing NaCN concentrations of 1000 ppm for the Aachen with bottle roll test (BRT) and 500 ppm for the Filblast with agitations leach test (ALT). Based on this study, each pre-treatment leaching reactor, the extraction percentages were 54.30% Au, 63,40%  Ag for the Aachen and 52.19% Au and 68,10% Ag at Filblast. Lime consumption in the Aachen was highest at 3.47 kg/t (PreOx 3 and AAL), while in Filblast at 1.71 kg/t. Meanwhile, NaCN consumption in the Aachen was highest at 0.64 kg/t (PreOx 2), compared to 0.80 kg/t in Filblast.

Stock returns are one of the indicators in investor investment decision making. Factors that influence stock returns are internal (fundamental) factors, namely ROA, DPR and EPS. The purpose of this study was to determine: the effect of Return On Asset (ROA) on Stock Returns, the effect of Dividend Payout Ratio (DPR) on Stock Returns, and the effect of Earnings Per Share (EPS) on Stock Returns in Industrial Sector companies listed on the Indonesia Stock Exchange in 2020-2022. The data analysis method used is multiple linear regression analysis. Findings: Return On Asset (ROA) has a positive and significant effect on Stock Returns, Dividend Payout Ratio (DPR) does not affect Stock Returns, and Earnings Per Share (EPS) does not affect Stock Returns. The implication of this study for investors is that they can use ROA as the main indicator in analyzing potential opportunities to gain profit from capital gains from stock returns before making investment decisions. The implication for management is to focus on strategies to optimize the use of assets to generate greater profits. Meanwhile, the implications for regulators and policy makers are to encourage transparency in financial reports and the preparation of capital market literacy programs.
