Abstract

PT. Petrokimia Gresik, the most comprehensive fertilizer agro-industry company in Indonesia, produces a product called Filler Plus, which requires dolomite as a raw material. Amid pressure from the government, especially on environmental issues, companies are creating production strategies that are environmentally friendly but also prioritize economic factors (economic profits) and the impact on the social environment. One of these strategies can be done by selecting the right supplier. This research evaluates supplier performance based on sustainable aspects (economic, environmental, social) using the cut-off point method for selecting sub-criteria, FAHP for weighting sub-criteria, and TOPSIS for ranking suppliers based on predetermined sub-criteria. This study uses qualitative and quantitative approaches. The research results show that supplier S2 is ranked highest with a coefficient value of 0.826, followed by S3 (0.442), S4 (0.357), and S1 (0.256). This study can serve as a basis for strategic decision-making in selecting sustainable dolomite suppliers by considering the most relevant criteria and sub-criteria.

Abstract

Warehouses have an important role because they influence operational activities in a company's business processes. PT. ABC is one of Pertamina's official distributors which is engaged in logistics and distribution activities for oil, fuel, and heating products. In carrying out its operational activities, PT. ABC is still faced with various problems. The occurrence of delivery delays due to waiting times that are too long is the main problem at PT. ABC. Therefore, this research aims to identify waste and provide recommendations for improvements to warehousing activities. The lean warehouse approach is used to identify and eliminate waste through value stream mapping and process activity mapping tools. The research results were obtained through predictions of the proposed improvement recommendations, where it can be seen that the highest type of waste is waiting. After the proposed improvements, warehousing activity time decreased from 526 minutes to 355 minutes. In addition, the overall efficiency of warehousing activities increased by 22.14%, from the previous 47.72% to 69.86%.

Abstract

This research aims to analyze the HOTS ability of elementary school students to solve science questions. The type of research used is descriptive qualitative. The research subjects were 7 class VI students at SDN 2 Ngepoh for the 2023/2024 academic year. Data collection methods were carried out through written tests, documentation, and interviews. The analysis technique used is the Miles & Huberman analysis method. The results showed that Of all 7 class VI  students, there was 1 student who had low ability and was unable to solve HOTS questions on all indicators, 3 students were able to solve HOTS questions on the  evaluating (C5), and 3 students were able to solve HOTS questions on the creating (C6) indicators. This research concludes that the HOTS ability of elementary school students to solve science questions is still low, this is because students are less able to understand concepts so that students have difficulty in solving the problems presented and there is a lack of practice in solving HOTS questions. This research implies the need to improve conceptual understanding and familiarization with HOTS questions in science learning to develop high-level thinking skills in elementary school students.

Abstract

Vocational education is a level of education that is the focus of development in Indonesia's 2045 vision. In 2045, it is predicted that 90% of workers will be dominated by the workforce from high school and university level. The aim of writing this article is to examine career development theories relevant to vocational education. The career theory relevant to vocational education is SCCT. The theory used in developing SCCT is a theory with the P-E Fit paradigm and Developmental Theory. One of the theories with the P-E Fit paradigm is the theory coined by Holland, namely RIASEC. This theory determines individual character based on 6 elements that are appropriate to the world of work. The next theory is Ginzberg's Developmental Theory. According to Ginzberg, career development is plotted into 3 age categories. SCCT is a development of previous theories (P-E Fit and Developmental Theory). Based on the previous discussion, RIASEC theory tends to discuss vocational interests, of which interest is one model of SCCT. Meanwhile, based on Developmental Theory Ginzberg has a position as a predictor of learning experience in the SCCT model.

Abstract

In an effort to manage and optimize the use of energy in these buildings, the ARIMA model (Autoregressive Integrated Moving Average) emerged as a very important analytical tool. The primary objective of this research is to investigate and explore how ARIMA parameter settings can be modified to improve the accuracy of energy consumption predictions on stairwell buildings. Based on an in-depth analysis of existing literature as well as empirical data, it was found that the ARIMA model, by leveraging time row kastasioneran and the use of univariate data, showed great potential in producing highly accurate short-term predictions. In this study, it was found that by performing the correct configuration of ARIMA parameters, the model was able to a level of accuracy with MAPE of 5,317% and RMSE of 8,7. These results show an excellent level of conformity, indicating that the ARIMA model can be effectively used to improve the accuracy of prediction of energy consumption in stairwell buildings. The findings of this study confirm that with proper adjustment of parameters, ARIMA can be a very useful tool in more efficient energy management in the building sector, which can ultimately contribute to reducing unnecessary energy consumption as well as improving overall energy efficiency.

Abstract

This study explores the marketing communication and distribution strategies of local films in Sidoarjo through a case study approach involving three active community-based film groups. The objective is to identify the distribution channels utilized, assess the effectiveness of promotional strategies employed, and evaluate the potential for community driven local films to develop independently and sustainably. The research applies a qualitative descriptive method, utilizing observation, in-depth interviews, and document analysis of the film communities’ activities. Findings indicate the use of five primary distribution channels: local film screenings, film festivals, roadshows, alternative screenings, social media, and digital platforms such as Digital TV. Among these, film festivals and alternative screenings emerged as the most dominant strategies due to their wider audience reach and their ability to foster public appreciation of local cinema. Furthermore, elements of the marketing mix such as ticket pricing, digital promotional strategies, visual design, and audience segmentation play a crucial role in strengthening the market positioning of these films. This research demonstrates that community-based local films in Sidoarjo possess the potential to grow independently and sustainably through alternative distribution and digital-based marketing efforts.

Abstract

Corncob was chosen as a raw material due to its high lignocellulose content, including 36.4% cellulose. The delignification process was performed using alkaline treatment with NaOH, enhanced by ultrasonik irradiation, creating cavitation that helps break lignin bonds, shortens processing time, and increases cellulose yield. The ultrasonic assistance aims to provide an optimal solution for lignin processing. Variables tested included ultrasonic power (80-120 watts) and delignification time (50-70 minutes). The study results indicated that both ultrasonic power and duration influenced cellulose content, with the highest yield of 66.08% achieved at 110 watts and 60 minutes. FTIR analysis showed a reduction in peak intensity, indicating lignin reduction, while SEM analysis confirmed significant surface morphology changes after delignification. In conclusion, the ultrasonic delignification method proved effective in separating cellulose from corncob, yielding better results and more efficient processing times, demonstrating the potential of ultrasonic technology in the biomass processing industry for more environmentally friendly and energy-efficient cellulose production. Further studies are recommended to optimize process conditions and evaluate industrial-scale applications.

Abstract

This study examines the impact of school management, organizational culture, and workload on junior high school teachers' performance in Meranti Islands Regency. Using a quantitative approach, this study involved 135 civil servant teachers from 41 junior high schools as the sample. Data were collected through questionnaires and analyzed using regression to examine the relationship between the independent variables (school management, organizational culture, workload) and the dependent variable (teacher performance). The results of the analysis show that simultaneously, the three independent variables have a significant effect on teacher performance. The calculated F value (8.945) is greater than the F table (2.67), with a significant value of 0.000 <0.05. The null hypothesis is rejected and the alternative hypothesis is accepted, indicating a significant impact of the three variables on the performance of junior high school teachers in Meranti Islands Regency. This study was limited to a population of junior high school civil servant teachers in Meranti Islands Regency, so the results may not be generalizable to other regions or employment statuses. The findings have practical implications for school managers and education policy makers to improve teacher performance through improved school management, organizational culture, and effective workload management.
