Abstract

Children have the right to receive education in a school environment that is safe, comfortable, and free from all forms of violence. In reality, however, bullying occurs in schools. The presence of bullying indicates that not all schools are capable of providing a safe and comfortable place for children to learn. Legally, bullying is a form of violence, as stated in Article 6 of the Ministry of Education and Culture Regulation No. 46 of 2023. Bullying in schools has negative effects on students, including victims, perpetrators, and bystanders. These effects may include a decline in self-confidence, mental health issues such as anxiety and depression, poor academic performance, feelings of isolation, and the risk of self-harm or suicide. Due to the negative impact of bullying on students' psychological, emotional, academic, and developmental well-being, the Legal Outreach Team from the Faculty of Law at UISU believes it is necessary to conduct legal outreach at SMK Nur Azizi Tanjung Morawa, Deli Serdang. The result was that the students gained knowledge about bullying, but they were still unaware of its legal consequences, the legal process for handling both the perpetrators and victims of bullying, and the negative aspects of bullying.

Abstract

Cocoa and coffee are well-known commodities in the world, including Indonesia. The seeds of cocoa and coffee are often utilized. Cocoa beans are usually processed into chocolate products, while coffee becomes a beverage product. Utilization of cocoa and coffee beans, and fruits produces waste, namely the skin. The more cocoa and coffee production, the more fruit skin waste. One of the efforts to utilize fruit skin waste is by extracting the antioxidant content from it. The choice of extraction method is important to produce extracts with the maximum amount of extract. Therefore, a study was conducted on the comparison of maceration and reflux extraction methods in determining the highest level of antioxidant activity. Cocoa and coffee fruit peels were extracted using ethanol, and the extracts were tested for antioxidant activity using DPPH with ascorbic acid as a positive control using UV-Vis spectrophotometry. The results of the antioxidant activity test conducted with the DPPH method showed that the IC50 value of macerated cocoa fruit peel extract was 5.440 ppm, and coffee was 62.99 ppm the reflux extract of cocoa fruit peel was 4.999 ppm, and coffee was 61.68 ppm. This shows that the maceration and reflux methods of cocoa can be categorized as very strong antioxidants and strong arabica coffee. from the two extraction methods of this study, it is concluded that there is no significant difference between maceration and reflux.

Laki-laki pada umumnya lebih kreatif dari pada perempuan. Temuan lain yang melibatkan 100 anak (50 lelaki, 50 cewek) diperoleh hasil bahwa rata-rata anak perempuan lebih tinggi dibandingkan dengan anak laki-laki.

Abstract

The economic development approach is proposed to people's economic actors, especially cooperatives and SMEs. Development aimed at cooperatives and MSMEs is expected to lead to a more coherent and balanced arrangement of the structure of national economic actors so that a strong and independent structure of national economic actors develops. Thus, Cooperatives and SMEs are the heart of the people's economy and the pioneers of the growth of people's economy.This study uses normative and empirical legal research, with a statutory approach (Statue Approach) and a case approach (Case Approach) and a conceptual approach (Conceptual Approach).Based on research data, the level of MSME actors who obtained the issuance of a Business Identification Number (NIB) based on risk-based business licensing through the OSS-RBA system, was very low, namely from the number of 26,150 MSMEs in 2021 who obtained NIB with MSME actors who had migrated under Government Regulations. Number 5 of 2021 in Articles 562 and 563 which came into force at the Investment Agency and One Door Integrated Services (DPMPTSP) in Medan City starting on August 4, 2021, until June 15, 2022, there were only around 693 MSME actors. So that the implementation of the Government Regulation has not been effective in the growth of MSME actors in Medan,This reality is inseparable from the obstacles in the growth of MSME actors in Medan, both internal constraints, regarding Human Resources at the Medan DPMPTSP who still do not understand and external constraints, related to awareness and legal culture of MSME actors, as well as new regulations. enforced. Finally, it is hoped that the Department of Cooperatives and the Medan DPMPTSP must continuously facilitate and provide socialization and technical guidance, as well as Assistance services for Filling Business Licensing to MSME Actors while for Human Resources in the Medan City DPMPTSP, must conduct training and comparative studies so that they can increase the growth of SMEs. Keywords: Legal Effectiveness, Risk-Based Approach OSS System (OSS-RBA) System, Micro, Small and Medium Enterprises (MSMEs), Medan City.

Abstract

The research is aimed to determine the effect of ash and cow manure on growth and yield of sweet corn cultivated on peat soil. Ash applied in this study was prepared from coffee skin. The research was carried out from April 8 to July 19, 2019,This research was conducted in Pontianak West Kalimantan. The experiment is arranged according to factorial randomize block design with two factors, i.e., dosage of ash (Factor A) and dosage of cow manure (Factor B). Factor A consists of three levels is, a1 (30 ton/ha equivalent to 15 kg/plot), a2 (40 ton/ha equivalent to 20 kg/plot), a3 (50 ton/ha equivalent to 25 kg/plot) and factor B also consists of b1 (10 ton/ha equivalent to 5 kg/plot), b2 (20 ton/ha equivalent to 10 kg/plot), b3 (30 kg/ha equivalent to 15 kg/plot). Each treatments is replicated 4 times, and each of this experimental unit has 8 sample crops. The results showed that the applicaros of 50 ton/ha of coffee husk ash and 30 ton/ha of beef cattle fertilizer was the best dose togrowth and yield of sweet corn on peat soil. Keywords: cow manure, coffee husk ash, peat soil, sweet corn.
