The Authority of the Indonesian Competition Supervisory Commission (KPPU) with the Competition and Consumer Commission of Singapore in the Case of the Acquisition of Uber by Grab
No full textIn economic activities, it is inseparable from the occurrence of competition between business actors. Competition in the business world is an activity recommended by law as a spice in the practice of business activities. In Indonesia, the institution that handles business competition is the Business Competition Supervisory Commission (KPPU). KPPU oversees all types of business activities, including acquisitions. Regarding the enforcement of business competition policies, it is not only applied by Indonesia, but other countries also apply it. One of them is Singapore. The commission that oversees business activities in Singapore is the Competition and Consumer Commission of Singapore (CCCS). The CCCS also oversees the act of acquisition. This research aims to find out the differences in the authority of KPPU and CCCS in deciding business competition cases and the differences in decisions applied by the two Commissions, especially in the case of Uber's acquisition by Grab. The research method used is normative juridical method with statutory, case, and comparative approaches, and qualitative data analysis.
The results showed that the differences in authority and legal policies between KPPU and CCCS affected the differences in handling and decisions on the Uber acquisition case by Grab. KPPU stated that there was no violation related to the Uber acquisition case by Grab while CCCS imposed a fine on both parties of IDR141 billion. This finding reveals the limitations of KPPU's regulation and authority in overseeing asset acquisitions that have the potential to reduce competition, in contrast to CCCS's broader and stricter authority in enforcing competition law. This research confirms the need to update regulations on asset acquisitions, so that the legal source that guides asset acquisitions is not only based on the Regulations of the Competition Supervisory Commission, but also based on a higher and stronger legal source, namely the Law.174 PagesSkripsi Sarjan
The Impact of Self-Reward in Improving Psychological Well-Being of Final Semester Undergraduate Students at the USU Faculty of Medicine
No full textFinal semester students often experience high psychological pressure, especially when facing their final project or thesis. This pressure can trigger stress that impacts psychological well-being. Medical school students are among the most vulnerable groups due to the rigorous education system, heavy academic load, and pressure to become a competent medical professional. The concept of self-reward emerged as a way to reduce stress and maintain psychological well-being. Selfreward is understood as a form of personal reward that individuals give to themselves after succesfully achieving a target or completing a certain task. This research uses a qualitative approach, where data i collected through in-depth interviews with a number of selected informants. The results showed that the practice of self-reward is able to have a positive impact on students such as in the aspects of self-acceptance, positive relationships with others, autonomy, mastery of the environment, life goals, and self-growth. Although self-reward is not very important, the end result of self-reward can have a positive impact om those who do self-reward.155 PagesSkripsi Sarjan
Fish Diversity and its Relationship with Physico-Chemical Water Factors in Toba Lake, Pangururan Disctrict, Samosir Regency, North Sumatra
No full textFish diversity is an important indicator in assessing the health of aquatic ecosystems. The ecosystem reflects the balance between species and environmental conditions. Toba Lake is the largest volcanic lake in Southeast Asia, the lake holds significant potential for fisheries resources; however, its sustainability may be threatened by declining environmental quality, particularly related to physico-chemical water factors. This study was conducted in Pangururan District, Samosir Regency, North Sumatra. The aim was to determine fish diversity and to analyze its relation to physico-chemical water parameters. The method used was purposive sampling at three observation stations: the port area, market area and domestic discharge site. The results showed that the fish collected from Toba Lake consists of 5 orders, 5 families, 6 genera and 7 species. The species with the highest density is Amphilophus citrinellus found at stations 1, 2 and 3. The Shannon-Wiener diversity index (H’) ranged from 1.501 to 1.803, indicating a low level of species diversity. The evenness index (E) ranged from 0.838 to 0.926, indicating a high level of species evenness. Based on correlation analysis revealed that physico-chemical factors— particularly Biological Oxygen Demand (BOD), nitrate and phosphate—had a very strong influence on fish diversity. Dissolved oxygen (DO) showed a strong influence, while temperature and pH had a moderate influence. Meanwhile, light penetration and light intensity had a weak influence on fish diversity.67 PagesSkripsi Sarjan
Potential and Utilization of Natural Dyes from Plants in the Arboretum of Universitas Sumatera Utara
No full textIn recent years, environmental issues have driven the search for more
environmentally friendly alternative materials in various industries. One of the
efforts utilized is the use of natural dyes derived from plants. The Arboretum of
Universitas Sumatera Utara (USU), which is a biodiversity conservation area, has
great potential as a source of natural dyes. Some plant parts such as leaves, bark,
flowers, and fruits are known to contain natural coloring compounds such as
anthocyanins, flavonoids, tannins, and carotenoids that can be used as food,
cosmetic, and textile dyes. This research was conducted using the census method,
by inventory, namely by analyzing all plant species in the Arboretum of USU area.
The results showed that there were 47 tree species and 28 families found in the
Arboretum of USU, with the Moraceae family being the most dominant. The tree
species with the highest number of individuals was Pulai (Alstonia scholaris), with
541 individuals or 11.83% of the total population. There were 60 species of
understory plants, with the most abundant being the sword fern (Nephrolepis
biserrata), numbering 11,812 or 17.05% of the total individuals. There are 33
species of understory plants and 21 species of trees that have the potential as
natural dyes, while the leaves that have the potential as pattern for ecoprint are 16

Transbahasa dalam Interaksi Sosial Guru dan Siswa di SLB Negeri 1 Binjai
No full textThis research explores classroom interactions focusing on translanguaging between teachers and students at SLB Negeri 1 Binjai, a special school in Indonesia. The main focus of this study is how teachers use Indonesian and English with students who have Autism Spectrum Disorder (ASD) during learning activities. Using Tse’s (1996) theory, the study identifies three parts of translanguaging: code- switching, translating/interpreting, and language brokering. This study uses a qualitative method through classroom observation, interviews with teachers, and documentation. The results show that the most common type of translanguaging used is intra-sentential code-switching, followed by inter- sentential code-switching, and a smaller number of tag-switching. Translating is also often used to help students understand English vocabulary. However, there is no language brokering done by students. Interviews with teachers show that translanguaging can be done by students with autism using simple language and simple materials to support English learning at this school.65 PagesSkripsi Sarjan
Factors Affecting Indonesian Ginger Exports to Bangladesh
No full textIndonesian ginger exports to Bangladesh have experienced fluctuations
influenced by various factors. This study aims to analyze the factors affecting the
volume of Indonesian ginger exports to Bangladesh during the period 2019–2023.
The factors analyzed include ginger production, ginger prices, the exchange rate
of the Rupiah against the US Dollar, and consumption in the destination country.
The data used in this research are secondary data obtained from the Central
Bureau of Statistics, Bank Indonesia, the World Bank, FAO, and other relevant
sources.
The analytical method employed is multiple linear regression to examine the
influence of these factors on the volume of ginger exports. The results of the study
show that ginger production, price, and consumption in the destination country
have a significant influence on the export volume of Indonesian ginger to
Bangladesh. Meanwhile, the exchange rate does not have a significant effect on
export volume. These findings indicate that increased production, stable prices,
and high consumption in the destination country can drive and enhance ginger
exports to Bangladesh. Therefore, the government and agribusiness stakeholders
need to adopt strategies to increase production and maintain price stability.65 PagesSkripsi Sarjan

No full textBackground
In the current era of industrialization, development is increasing rapidly, which also increases the risk of occupational lung disease, one of which is pneumoconiosis. Workers in cement industries, who are continuously exposed to cement dust, are at high risk of developing pneumoconiosis. Cement dust contains harmful components like silica and calcium, which can cause inflammation in the respiratory tract. This research aimed to identify the risk factors associated with the occurrence of pneumoconiosis among workers.
Research Objectives
To analyze the occurrence of pneumoconiosis among workers at PT. X cement factory in Medan. This study aims to identify the risk factors associated with the occurrence of pneumoconiosis among workers, including individual factors such as age, gender, education, smoking habits, and occupational factors like PPE use, work duration, and respiratory symptoms.
Research Method
This research used an analytic approach with a cross-sectional design. The sample consisted of 43 workers from PT. X cement factory in Medan, selected through consecutive sampling. Data were collected through interviews, questionnaires, physical examinations, and chest radiographs to assess respiratory symptoms.
Research Results
Significant relationship was found between respiratory symptom with pneumoconiosis incidences. No significant relationship was found between individual factors (age, gender, education, smoking habits) and occupational factors (PPE use, work experience, work location, and respiratory symptoms) with pneumoconiosis incidences. Despite exposure to cement dust, occupational factors and smoking habits were not directly related to the disease occurrence. The study recommends further research with a larger sample size and detailed dust level measurements. Conclusion
Occupational factors and smoking habits did not show a significant relationship with the occurrence of pneumoconiosis among workers at PT. X cement factory in Medan. Despite exposure to cement dust, individual factors and occupational risk control through the use of PPE and other preventive measures need to be improved.101 PagesTesis Magiste
