Abstract

This study aims to analyze the influence of Product, Price, and Place on the purchase decisions of Tomoro Coffee products among the people of Sumbawa Regency. The cultural shift of coffee consumption from a functional need to a modern lifestyle has contributed to intense competition in the coffee shop industry, including in developing regions such as Sumbawa. Tomoro Coffee has emerged as a new brand with an aggressive pricing strategy, claimed premium product quality, and strategically located outlets. This research employs a quantitative approach using a survey method involving 100 respondents who are Tomoro Coffee consumers in Sumbawa. The analytical technique used is multiple linear regression to measure the partial influence of each variable. The results show that all three variables, Product, Price, and Place, have a positive and significant effect on purchase decisions. Among them, Price has the strongest influence, followed by Place and Product. These findings offer strategic implications for F&B businesses in designing effective marketing mixes in regional markets and emphasize the importance of perceived quality, price affordability, and outlet location in shaping consumer purchase decisions. Additionally, this study contributes to the marketing management literature by providing empirical insights from a non-metropolitan area in Indonesia.

Abstract

Electricity demand forecasting is crucial for effective energy management, particularly in regions with unique consumption patterns like Palangkaraya. This study explores the application of Artificial Neural Networks (ANN) enhanced by Particle Swarm Optimization (PSO) to improve forecasting accuracy. While traditional ANN models offer robust capabilities for handling nonlinear data, their performance is often limited by the challenge of identifying optimal model parameters. By integrating PSO, this research aims to refine parameter selection, thereby enhancing the predictive precision of the ANN model. The study compares the performance of the standalone ANN model and the ANN-PSO hybrid model. Results demonstrate that the ANN-PSO model significantly outperforms the standard ANN, achieving a Mean Absolute Percentage Error (MAPE) reduction from 10.34% to 3.05%, and Root Mean Square Error (RMSE) improvement from 1,061,485.57 to 366,879.94. These findings underscore the capability of the ANN-PSO approach to better capture the intricate patterns in electricity consumption data. The proposed model adapts effectively to the localized energy consumption characteristics in Palangkaraya, offering actionable insights for energy planners. By leveraging the strengths of both ANN and PSO, this research contributes to the development of more accurate and reliable forecasting tools, paving the way for optimized energy management strategies.

Abstract

The enactment of Law Number 12 of 2022 concerning Criminal Acts of Sexual Violence in harmony with Islam, as stated in the Qur'an, QS. An-Nur verse 33. Prohibiting violence against women also contradicts the values of monotheism, and Al-Insaniyah is a concrete manifestation and gift for women in Indonesia. It has very comprehensive content regulating the classification of criminal acts of sexual violence, physical sexual harassment, forced contraception, forced sterilization, forced marriage, sexual torture, sexual exploitation, sexual slavery, and electronic-based sexual violence. It establishes appropriate penalties and optimizes the prevention and handling of cases of sexual violence in Indonesia, which continues to show a high level every year. However, its implementation has not been as optimal as desired by victims and the public due to several obstacles, including: 1) Not all derivative regulations of the TPKS Law have been enacted; 2). Limited human resources, facilities, infrastructure, and operational costs, and only 30 percent of districts/cities in Indonesia have safe houses for victims of sexual violence.

Abstract

Saudi Arabia and Iran are two countries that serve as powerhouses in the Middle East region. They severed diplomatic relations following the vandalism and arson of the Saudi Arabian embassy in Iran in 2016. The attack was a response by the Iranian public to the Saudi government's execution of Sheikh Nimr al-Nimr. In 2023, Iran and Saudi Arabia normalized diplomatic relations through several agreements, including the reopening of embassies and the reactivation of security and trade agreements, facilitated by China in Beijing. This study focuses on the reasons why China chose to act as a mediator in the normalization process between Saudi Arabia and Iran. The research uses a qualitative-explanatory approach through the perspective of the Rational Actor Model. It is found that China's decision to act as a mediator was a rational choice that yielded more benefits through a cost-benefit analysis. These benefits include securing energy supplies, ensuring a stable investment climate, reducing the risk of cooperation failures, and opening up opportunities for further collaboration. On the other hand, the costs borne by China include the diplomatic burden of having to succeed in this mediation and the future expectations placed on China to maintain these benefits. An alternative policy is bilateral hedging, which also presents potential advantages such as saving diplomatic resources and fostering short-term trade relations. However, it also comes with drawbacks such as energy supply disruptions, damage to the investment climate, and the loss of strategic momentum and trust for China.

Abstract

Organ transplantation is a surgical procedure intended to replace a completely damaged or non-functioning organ with healthy tissue obtained from a donor. This process, as regulated under Article 124 paragraph (1) of the Health Law, is conducted to cure certain medical conditions, restore essential bodily functions, and must be carried out solely for humanitarian purposes. Furthermore, Article 124 paragraph (3) prohibits any form of trade involving human organs or tissues, highlighting the ethical and legal concerns associated with commercialization. Therefore, understanding and analyzing the legal framework governing organ transplantation is of critical importance to ensure compliance with national regulations and uphold ethical standards in medical practice. This research adopts a normative legal approach, focusing on the analysis of laws and regulations. In Indonesia, legal aspects of organ transplantation are regulated by Law No. 1268/2001, and further supported by several ministerial regulations, including Minister of Health Decree No. 17 of 2023, No. 53 of 2021, and Ministerial Regulation No. 38 of 2016.

Abstract

This study aims to empirically examine the relationship between optimism and peer support on the resilience of adolescents who have lost a parent. Participants were adolescents aged 12-18 who had lost a parent due to the death of one or both (orphans, orphans, orphans). This study used a quantitative correlation method. The sampling technique used was quota sampling, with a sample size of 100 respondents. Data collection tools included resilience scales, optimism scales, and peer support scales. The results of the minor hypothesis analysis on the optimism and resilience variables yielded an rx1y of 0.662 and a p-value of 0.000 (p<0.01), with an effective contribution of 43.8%. This indicates a highly significant positive relationship between optimism and resilience in adolescents who have lost a parent, thus accepting the first hypothesis. The minor hypothesis analysis on the peer support variable and resilience yielded an rx1y of 0.581 and a p-value of 0.000 (p<0.01), with an effective contribution of 33.7%. This indicates a highly significant positive relationship between peer support and resilience in adolescents who have lost a parent, thus accepting the second hypothesis. The correlation coefficient for the three variables, rx12y, was 0.743 and a p-value of 0.000 (p<0.01), with an effective contribution of 55.3%. This indicates that the major hypothesis is accepted, indicating a highly significant relationship between optimism and peer support and resilience in adolescents who have lost a parent.

Abstract

The selection of appropriate medication based on the symptoms experienced by patients is a crucial aspect of healthcare services, particularly in clinics like Klinik K-24 that handle various complaints quickly and efficiently. A common issue encountered is the subjectivity in medication selection, which can lead to inappropriate therapy and potential unwanted side effects. To address this issue, a system is needed that can assist in making objective and structured decisions. This study aims to design and develop a Decision Support System (DSS) to assist doctors or medical personnel at Klinik K-24 in determining the most appropriate medication choices based on the symptoms reported by patients. The method used in this research is the Analytical Hierarchy Process (AHP), which breaks down complex problems into a hierarchical structure and then compares criteria and alternatives to generate priority weights. The decision-making criteria include the effectiveness of the medication for the symptoms, side effects, availability in the clinic pharmacy, and medication cost. The medication alternatives analyzed are based on common symptoms such as fever, cough, and sore throat. The system's results show that the AHP method can provide structured medication recommendations with an acceptable level of consistency (CR < 0.1). With this DSS, the medication selection process is expected to become faster, more accurate, and standardized, thereby supporting the efficiency of medical services at Klinik K-24.

Abstract

The increasing demand for fossil fuel energy (BBM) has driven the development of renewable energy sources, one of which is biodiesel derived from microalgae. Chlorella sp. is a promising microalga due to its high lipid content. This study aims to determine the optimal concentration of tempeh wastewater for culturing Chlorella sp. to maximize lipid production as a raw material for biodiesel. The culture was carried out for five days using different treatments of tempeh wastewater: 0% (control using Walne fertilizer), 3%, 5%, 7%, and 9%. Observed parameters included temperature, pH, dissolved oxygen, nitrate, phosphate, cell density, and lipid content, with lipid extraction performed using the Soxhlet method. The culture temperature ranged from 25-27°C, pH increased from acidic to neutral, and dissolved oxygen levels decreased at higher wastewater concentrations. The highest cell density was found in the 7% treatment (8.45 million cells/mL), although it was not significantly different from the other treatments. The highest lipid content was obtained at 3% wastewater (40.3%), which was higher than the control (21.3%) and other treatments. The decrease in lipid content at higher wastewater concentrations was attributed to toxicity and reduced media quality. It is concluded that a 3% concentration of tempeh wastewater is optimal for enhancing lipid production in Chlorella sp. as a sustainable biodiesel feedstock.

Abstract

Vocational education, particularly Vocational High Schools (SMK), plays an important role in preparing graduates who are ready to work or continue their studies. However, the Culinary Arts program at SMK Negeri 2 Gunung Talang still faces low student enrollment. This study aimed to examine the relationship between vocational school information and junior high school students’ interest in choosing the culinary expertise program. Using a quantitative correlational design, the population consisted of 869 ninth-grade students in Gunung Talang District, with 274 students selected through proportional stratified random sampling. The research instrument was a Likert-scale questionnaire tested for validity and reliability (α = 0.627 for information; α = 1.000 for interest). Results showed that the average score of vocational school information was 82.80 (SD = 9.629), categorized as fairly good, with the highest indicator being facilities and infrastructure (mean = 2.86) and the lowest being sources of information (mean = 2.60). Students’ interest scored an average of 95.80 (SD = 13.528), also fairly good, with the highest indicators on personality (mean = 2.89) and socio-cultural environment (mean = 2.87). Pearson correlation analysis revealed a strong and significant positive relationship (r = 0.678; p = 0.000) between vocational school information and students’ interest. These findings highlight the importance of quality and accessible information in shaping students’ interest, emphasizing the need for schools to optimize information dissemination strategies to strengthen the attractiveness of the culinary program.
