Abstract

The risk of degenerative diseases is increasing due to unhealthy lifestyles. Many people consume junk food, smoke, and do not protect themselves from sun exposure and pollution, exposing their bodies to free radicals. Free radicals can cause oxidative stress, necessitating the need for antioxidants to neutralize them. The leilem plant (Clerodendrum minahassae) is an endemic plant from North Sulawesi that is often used in traditional dishes and medicine. Moreover, leilem leaves are believed to be a source of natural antioxidants. This study aimed to determine the efficacy of leilem leaf ethanol extract as a source of antioxidants. The antioxidant potential was evaluated using phytochemical screening and antioxidant assays such as 2,2-Diphenyl-1-Picrylhydrazyl (DPPH) and Ferric Reducing Antioxidant Power (FRAP) methods, with ascorbic acid as a comparison. The level of antioxidant activity was measured by determining the IC50 value, which corresponds to the concentration of extract required to inhibit 50% of free radicals. The results of phytochemical screening showed that the ethanol extract of leilem (Clerodendrum minahassae) leaves contains active compounds such as phenols, flavonoids, saponins, tannins, steroids/triterpenoids, and alkaloids, indicating a high potential for antioxidant activity. The IC50 value for the DPPH method was 78.799 ppm, and the IC50 value for the FRAP method was 92.127 ppm. These results demonstrate that the ethanol extract of leilem leaves has strong antioxidant activity in both the DPPH and FRAP methods.

Abstract

The big earthquake has an impact on the risk of injury to the victims. The wounded victim needed urgent medical assistance to survive. The effectiveness of this service depends heavily on the response speed of stakeholders. To increase the response rate, a detailed emergency response plan is needed. The study aims to identify restrictive factors in evacuating victims of post-earthquake injuries. This qualitative research has a phenomenological design. Participants in this study were 15 nurses who participated in the Disaster Victim Evacuation (DVE) process and who met the criteria with the purposive sampling technique. Data is collected through a deep interview (IDI) using open questions. Data analysis is done using the inductive content analysis method. Two themes contributed to the DVE process as an ERP, namely, 1) restriction of institutional support and 2) cancellation of evacuation routes. These findings have provided an overview of several factors that directly contributed to the implementation of the DVE process.

Abstract

The number of early marriages in Central Kalimantan Province, Indonesia, has increased yearly. According to data from the Indonesian Office of Religious Affairs (KUA) and Office of Population and Civil Registration (Dukcapil), 14,540 couples married early between 2017 and 2021. This problem is caused by several factors, including teenagers' knowledge, parents' education, parents' income, parents' perceptions, and support from parents and peers. This research analyzes factors related to early marriage in Banama Tingang District, Pulang Pisau Regency. This quantitative study used a case-control design conducted in Banama Tingang District, Pulang Pisau Regency, in November 2022. The sample was determined using convenience or accidental sampling methods with 200 teenagers. The results of the Chi-Square analysis showed significant associations between early marriage and parental education (p=0.000) and parental income (p=0.022) but not with adolescent knowledge (p=1.000), parental perception (p=0.173), or parental and peer support (p=0.252). Logistic regression analysis revealed that parental education was the most dominant variable significantly associated with early marriage (p=0.000, Exp B=3.169). There was no significant relationship between adolescent knowledge, parental perception, or support from parents and peers with early marriage among adolescent girls in Banama Tingang District, Pulang Pisau Regency. In conclusion, parental education and income were found to be associated with the incidence of early marriage among young women in Banama Tingang District, Pulang Pisau Regency, with parental education being the most dominant factor.

Abstract

This research addresses the critical need for increased energy efficiency in communities, emphasizing the pivotal role of community involvement and awareness. With the growing concern for sustainable energy practices, empowering communities to contribute to energy efficiency initiatives is imperative. Thus, the research aims to investigate and understand the role of community empowerment in increasing energy efficiency through community role and awareness. The theory applied to the research is the theory of planned behavior. A descriptive quantitative approach is employed, utilizing a structured questionnaire based on the Likert scale. Then, after the questionnaires were collected, statistical data processing was carried out using the T-test, F-test, and validity and reliability tests. The questionnaire gauges participants' perceptions and behaviors about energy efficiency, enabling a comprehensive analysis of the community's role and awareness in promoting sustainable energy practices. Preliminary findings indicate a positive correlation between community empowerment, heightened awareness, and increased energy efficiency. The Likert scale responses provide valuable insights into the areas where communities excel and areas that require targeted interventions. The data also reveal notable patterns in community behaviors and perceptions of energy consumption and conservation. In conclusion, the research underscores the significance of community empowerment as a catalyst for enhancing energy efficiency. The findings suggest that fostering community awareness and active involvement can lead to tangible improvements in sustainable energy practices. This study contributes valuable insights for policymakers, community leaders, and energy advocates seeking effective strategies to address the global energy challenge through localized, community-driven initiatives.

Abstract

Indonesia, a country rich in geothermal resources, has yet to fully exploit its potential, particularly in volcanic regions like Mount Seulawah Agam. This study investigates the application of the Additive Ratio Assessment (ARAS) method for the site selection of Geothermal Power Plants (GPP) in Indonesia. The ARAS method provides a systematic approach to evaluating and prioritizing geothermal development sites by integrating multiple criteria, including geological, environmental, and socio-economic factors. The study collects data from various sources and weights criteria using the Ordinal Priority Approach (OPA), incorporating expert opinions. The findings demonstrate the effectiveness of the ARAS method in identifying optimal locations for GPP development, ensuring sustainability and feasibility. The study also tests the ARAS method in existing GPP locations in Jaboi, Sabang, Indonesia, to investigate alignment with the results and validate the approach. Furthermore, the study presents recommendations for GPP site selection. This research emphasizes the significance of multi-criteria decision-making techniques in facilitating renewable energy projects. It promotes a more systematic and informed approach to geothermal energy development in Indonesia and other geothermal-rich regions.
