    The Mechanism for Proposing Prospective Candidates for President and Vice President by Political Parties from the Perspective of Constitutional Law in Indonesia and the United States

    No full text
    The proposal of prospective candidates for President and Vice President constitutes the authority of political parties within the Indonesian constitutional system. This research compares the mechanisms for proposing prospective candidates in Indonesia and the United States in order to formulate an ideal concept for the nomination of presidential and vice-presidential candidates. Based on this background, the research addresses three main issues: the role of political parties in proposing prospective candidates for President and Vice President within the Indonesian constitutional system; the mechanism for proposing prospective presidential and vice-presidential candidates in the constitutional system of the United States; and the ideal concept of the nomination mechanism in Indonesia based on a comparison with the United States. This research employs a normative juridical method using statutory, conceptual, and comparative law approaches. The data were obtained from primary legal materials, secondary legal materials, and relevant non-legal materials, which were then qualitatively analyzed to understand the normative framework and practical implementation of the nomination of presidential and vice-presidential candidates within the party systems of Indonesia and the United States. The findings indicate that the mechanism for proposing prospective candidates for President and Vice President in Indonesia remains centralized and elitist, with dominant authority concentrated among central party elites and limited involvement of party members and voters. In contrast, the nomination mechanism in the United States is conducted in a more open and participatory manner through the primary and caucus processes at the state level, which directly influence the selection of candidates at the party’s national convention. Based on this comparison, the research emphasizes the importance of formulating an ideal mechanism for proposing presidential and vice-presidential candidates in Indonesia that is more democratic, transparent, and accountable within the framework of the party system.166 PagesSkripsi Sarjan

    Water is a basic necessity for all living things, especially humans, so its quality must remain clean and free from pollution. One source of clean water that is widely used is groundwater from wells. However, groundwater is susceptible to pollution, one of which is by leachate from landfills that can contain heavy metals such as manganese, which have a negative impact on the environment and human health. This study aims to analyze the manganese (Mn) content in well water and health complaints in the community around the Terjun Landfill, Medan Marelan District. This study is analytical with a cross-sectional design. Well water samples were taken from 10 houses located <250 m from the Terjun Landfill and 28 respondents. The water sample testing method used an ICP-OES tool and the results obtained were three well water samples above the maximum levels set by the Minister of Health Regulation No. 2 of 2023 (0.1 mg/l), namely 1.250 mg/l, 0.786 mg/l, and 0.382 mg/l. There was no significant relationship between the distance of the well and the manganese content in the well water (p=0.129). A total of 89.3% (25 people) did not experience health complaints related to manganese exposure. Those who experienced complaints in the form of tremors were 7.1%, difficulty maintaining balance was 7.1%, muscle stiffness was 3.6% and all of them occurred infrequently. Based on the results of the analysis of the risk of manganese exposure to health, the RQ results for all respondents were still below 1, which means that exposure was still within safe limits and residents who consumed the water were not at risk of experiencing health problems. It is hoped that the community will not use well water as drinking water because there are manganese levels in all well water even though they have different concentrations.112 PagesSkripsi Sarjan

    Analysis of Surname Attribution Through the Mangain Process for Non-Batak Toba Ethnic Groups (Study of Balige District Court Decision No.19/Pdt.P/2020/Pn Blg)

    No full text
    Inter-ethnic marriages have become increasingly common in the era of urbanization and migration. Batak Toba cultural figures and scholars have sought solutions to accommodate the changing societal conditions. Individuals who have undergone Mangain are entitled to bear the surname (marga) of the adoptive family in accordance with Batak Toba customs. The request to change one's name to include a marga in official identity documents is crucial for the Batak Toba people. Permission for name change is subject to fulfil civil administrative requirements and obtain legal certainty as regulated by Law No. 23 of 2006 (Administrative Adulthood). This study employs a normative juridical legal research approach, supported by empirical data, with a descriptive analytical research nature. The research methodology incorporates a statute approach and a case approach. The data used consists of primary data obtained from court cases and interviews with judges, and secondary legal sources. Data collection methods involve literature reviews and field studies. Empirical data for this study was collected from the Head of the Civil Registration at the Population and Civil Registration Office of Medan City. The results of this study show that the court's decision to reject the request on the grounds that it did not meet the adoptive requirements stipulated in Government Regulation No. 54 of 2007 on the implementation of adoption, and because it deems the request was deemed to potentially obscure the applicant's original identity. However, in Batak Toba customary law, particularly the marga (surname) system, marga in identity documents is highly significant, as it determines one's position within the extended family and clarifies lineage status.115 PagesTesis Magiste

    No full text
    Background: Young coconut coir contains 69% cellulose making it a potential source for sodium carboxymethyl cellulose production. Objective: This study aimed to utilize young coconut coir and determine the optimal sodium hydroxide concentration in the delignification process to obtain high quality alpha cellulose and produce sodium carboxymethyl cellulose as a pharmaceutical additive, specifically a gelling agent. Method: The isolation process started with delignification using the alkaline hydrolysis method with sodium hydroxide concentrations of 5%, 10%, and 15%, followed by bleaching with alkaline hydrogen peroxide (AHP), and purification with 17.5% sodium hydroxide. The obtained alpha cellulose was then synthesized into sodium carbocymethyl cellulose, characterized, and applied as a gelling agent.. Results: High quality alpha-cellulose characteristics were obtained from delignification using 10% NaOH, yielding 17.73 ± 1.39% in the form of fine, white, odorless fibers. Sodium carboxymetyhl cellulose produced from young coconut coir exhibited good characteristics, confirmed through SEM, FT-IR, and XRD analyses. The degree of substitution was 0.55 (grade quality II), the viscosity of a 2% Na-CMC solution was 401.33 ± 12.76 cP (medium viscosity), and the crystallinity percentage was 26%, indicating low crystallinity. Sodium carboxymethyl cellulose derived from young coconut coir, applied as a gelling agent in ibuprofen gel preparation, met the physical evaluation and stability tests at room temperature (28±2°C), low temperature (4±2°C), and high temperature (40±2°C), based on organoleptic, pH, and viscosity assessments. Conclusion: The alkaline hydrolysis delignification method effectively produces alpha-cellulose from young coconut fiber. The resulting Na-CMC has the potential to serve as a gelling agent that meets industry standards.152 PagesSkripsi Sarjan

    Study on Soil and Water Characteristics After Biodegradation of Palm Oil Trunk Starch-Based Bioplastic

    No full text
    The increasing use of conventional plastics has raised serious environmental concerns. Bioplastics, as an environmentally friendly alternative, have attracted considerable attention. This study aims to analyze the characteristics of soil and water following the biodegradation of bioplastics made from palm oil trunk waste starch. The bioplastic used in this study was produced using starch derived from palm oil trunk waste. Post-biodegradation, the soil and water samples were analyzed for several parameters. For water, the parameters included pH, Total Suspended Solids (TSS), and Biological Oxygen Demand (BOD); for soil, pH and organic matter content were measured. The analyses were conducted using standard methods established by health and environmental agencies. The results indicate that the biodegradation of bioplastics derived from palm oil trunk starch has a positive impact on soil and water characteristics. In soil, the pH levels of Andosol and Podsolic soils returned to stability after a temporary decrease, accompanied by an increase in organic carbon content, especially in Andosol, which enhanced soil fertility. In seawater and river water, biodegradation led to an increase in TSS and BOD levels, indicating higher microbial activity. Based on the BOD test results, the biodegradation process is still in the exponential phase, characterized by rapid microbial growth and active organic matter degradation. However, the process has not yet entered the mortality phase, where the degradation rate slows due to resource depletion. Overall, this biodegradation process is safe for soil and water quality, supports ecosystem health, and represents an environmentally friendly alternative for waste management.147 PagesSkripsi Sarjan

    No full text
    TBKSafety behavior refers to the actions taken by workers to minimize the risk of accidents and maintain safety in the workplace. These behaviors include compliance with safety protocols, the use of personal protective equipment (PPE), proactive reporting of hazardous conditions, and participation in activities that promote workplace safety. This study aims to identify the factors influencing safety behavior among workers at PT. Toba Pulp Lestari, Tbk in 2023. The research is quantitative with a cross-sectional approach. Data analysis includes univariate analysis, bivariate analysis using the chi-square test, and multivariate analysis using logistic regression (α = 0.05). The univariate analysis results show that the majority of workers have good knowledge (96.6%), demonstrate safe actions (98.7%), hold positive perceptions (99.3%), receive support from co-workers (87.9%), and have active supervisory roles (96.6%). Additionally, most workers exhibit safe behavior (97.3%). The chi-square test results indicate no significant relationship between knowledge (p-value = 0.592), attitude (p-value = 0.772), and perception (p-value = 0.813) with safety behavior. However, the variables of co-worker support (p-value = 0.001) and supervisory role (p-value = 0.000) show significant relationships. Multivariate analysis reveals that the supervisory role is the most influential factor on safety behavior. It is recommended that the company focus on strengthening knowledge, attitudes, perceptions, co-worker support, and the supervisory role to build a better safety culture in the workplace.206 PagesTesis Magiste
