Personal Protective Equipment (PPE) is essential for worker safety, especially in oil palm harvesting activities. PT Langkat Nusantara Kepong faces major challenges related to work safety, with analysis showing that work accidents still occur frequently in the Padang Brahrang Plantation. This indicates the need for an in-depth evaluation of the use of Personal Protective Equipment (PPE) to reduce the risk of work accidents. By using the clustering method to group data based on the type of Personal Protective Equipment (PPE) used and aims to provide recommendations for optimizing the use of personal protective equipment based on risk management and reducing the incidence of work accidents. From testing the results of cluster 3, cluster 4 and cluster 5 it can be concluded that clustering with 5 clusters provides the most efficient and precise results, followed by 4 clusters, while 3 clusters provide greater variation within clusters, indicating that clustering with fewer clusters is less able to capture subtle differences in the data.

Agricultural waste, when managed properly, is not merely production residue but also holds significant economic potential. Margomulyo Village, as a major corn-producing center, has abundant corn waste. To address the waste problem and simultaneously boost the village's economy, the production of corn briquettes is an attractive alternative. Corn briquettes, as a biomass-based alternative fuel, are rich in carbon content and can be utilized as a clean energy source.

Breast cancer is a type of cancer that affects the breast organs and is characterized by abnormal cell growth and development. The treatment for breast cancer can impact both the physical and psychological conditions of patients. One of the physical impact is body image, while the psychological impact includes the emergence of negative feelings that can affect breast cancer patients’ self-efficacy. This study aims to determine the relationship between body image and self-efficacy in breast cancer patients. The study was conducted at Dr. Kariadi Central Public Hospital Semarang, with a sample size of 63 respondents. The sampling technique used was purposive sampling, where subjects were selected based on inclusion criteria set by the researcher. The instruments used in this research were the Body Image Scale and the General Self-Efficacy Scale. This study employs quantitative methods with a cross-sectional research design. Based on the Spearman rank statistical test, the p-value was 0.000 (<0.05), indicating that Ha is accepted, and Ho is rejected. This shows that there is a significant correlation between body image and self-efficacy in breast cancer patients at Dr. Kariadi Central Public Hospital Semarang. It is hoped that the recommendations from the research results can enhance nursing knowledge related to body image and self-efficacy in breast cancer patients.

Nolokerto Village is a developing village and most of the businesses owned by the village, one of which is a catering business, produce a lot of organic waste that has a high water content, especially those that are easily decomposed. Unmanaged organic waste can cause environmental problems. Realizing the importance of effective waste management, KKN UIN Walisongo Semarang students held counseling and compost training activities so that food waste can be processed and reused. The program began with general materials on waste, followed by training on compost fertilizer for organic waste. The resulting compost fertilizer is then distributed to villagers to support agriculture and reduce the environmental impact of organic waste.

The success of the learning process is highly desired in school education. One of the key factors in achieving success is the teacher's selection of appropriate methods for delivering the lesson material in class, which contributes to students' learning outcomes. In mathematics instruction, particularly on the topic of Statistics in class X-7 at SMA Negeri 9 Surabaya, the results have been unsatisfactory, with an average score of 59 for the 2023/2024 academic year. Therefore, improvement is needed through the implementation of the Team Assisted Individualization (TAI) cooperative learning model. The subjects of this study are students of class X-7 at SMA Negeri 9 Surabaya for the 2023/2024 academic year, consisting of 36 students. This study involves a mathematics teacher and an observer. The data collection tools used include formative tests, observation sheets for the teacher, students, and group discussion activities, as well as reflection questionnaires on the learning process. Based on the research findings, it can be concluded that the application of the TAI cooperative learning model can improve the learning outcomes of class X-7 students at SMA Negeri 9 Surabaya on the topic of Statistics. This study is expected to encourage teachers to implement the TAI cooperative learning model in Statistics to enhance students' learning outcomes in Mathematics.

Managing plastic waste, which continues to increase, is a global challenge that requires sustainable solutions. One approach that can be applied is community empowerment through making ecobricks. Ecobricks are a method of managing plastic waste by using plastic bottles as containers to fill non-organic waste, thereby producing environmentally friendly building materials. This research aims to identify the impact of community creative empowerment through an ecobrick making program in the context of reducing plastic waste in the local environment. The methods used in this research include a participatory approach through training, counseling and direct observation in the community. The research results show that community involvement in making ecobricks not only contributes to reducing the volume of plastic waste, but also increases environmental awareness and community creativity. In addition, this program has a positive impact on local economic development through the potential use of ecobricks as an alternative construction material. In conclusion, community empowerment through making ecobricks is an effective step in overcoming the problem of plastic waste while empowering communities in a sustainable manner.

Stunting is a long-term nutritional problem that severely affects children's physical growth and cognitive development. To address stunting, Rejosari Village has developed various community-based initiatives. The purpose of this study is to find out how the Rejosari Village community functions to prevent stunting in children by using cooperation and participation strategies. Socialization of stunting, nutrition counseling for pregnant women and breastfeeding mothers, routine monitoring of pregnant women's health, and provision of supplementary food for children under five are some of the programs in which the community is actively involved. Village health cadres also play an important role in supporting the implementation of these programs by providing direct instruction and guidance to residents. A qualitative case study was conducted to collect data through field observations and interviews. The results showed that community involvement not only increased awareness of the importance of preventing stunting but also increased active participation in maintaining the health and nutrition of children in Rejosari Village. The village experienced a decrease in stunting rates due to strong community participation, which was supported by the village government and non-governmental organizations. The results suggest that the community-based intervention model used in Rejosari Village can be adapted and applied in other villages facing similar problems in preventing stunting.

This study aims to determine the effect of monetary policy on economic growth. This study uses the Vector Autoregression method by completing the assumption test and estimation on the research variables of inflation, investment, credit, interest rates and gross regional domestic product. Time series research data from 2003-2022 sourced from the Central Bureau of Statistics of North Sumatra (BPS) SUMUT with the results obtained are inflation and interest rates give the results that inflation is influenced by investment and credit, until investment affects gross regional domestic product. Then credit also affects inflation and interest rates and gross regional domestic product is influenced by investment and credit. Thus, in determining policies that encourage economic growth the government must consider a more coordinated monetary policy strategy to deal with the dynamics of strengthening interest rates, controlling inflation, can be measures that support economic stability.
