    No full text
    This study aims to describe the functions, manufacturing techniques, and playing techniques of traditional Nias musical instruments, namely the Aramba and Faritia, as practiced by Mr. Faozisökhi Laia at the Nias Heritage Museum Studio in Gunungsitoli City. These two instruments hold an important position in Nias culture, both as accompaniment for traditional ceremonies and weddings, and as a means of musical communication in a social context. This research is qualitative-descriptive in nature. Data was obtained through in-depth interviews, participatory observation, and direct documentation of the process of making and playing the Aramba and Faritia. Data analysis was conducted through data reduction, data presentation, and conclusion drawing based on the framework of ethnomusicology theory. In this study, the author used several theories, namely Khasima Shusumu's contextual approach to music studies. The author also used Bruno Nettl's theory to analyze and transcribe the playing of the Aramba and Faritia. The author also used Curt Sach and Hornbostel's theory of musical instrument classification to classify Aramba and Faritia. Then, the theory of physical behavior was used to describe the body position when playing musical instruments. The results showed that the sounds of Aramba and Faritia were originally found in one musical instrument, namely Tutuhao. Aramba and Faritia are not only musical instruments, but also rich in cultural and symbolic values. The manufacturing process involves traditional skills with special materials, stages of burning/heating, forming the Aramba and Faritia molds, the process of mamatö the Aramba and Faritia molds, the process of forming the Aramba and Faritia hagu, and the refinement process. The technique for playing the Aramba is to hang it on a support pole, and generally the player's body position when playing the Aramba is to stand sideways and hold the Aramba mallet. The Aramba player will play the Aramba by striking the hagu (pencu) on the Aramba, while performing foot and hand movements like a dancer. Similar to Aramba, Faritia is also played in a standing position, except that Faritia is played by two people playing two Faritia instruments, one person playing Faritia with a low sound and the other playing Faritia with a slightly higher tone. Each player is responsible for playing Faritia according to their assigned tasks and predetermined playing patterns. The two players stand facing each other, making small movements such as swinging their legs alternately. Aramba and Faritia produce the following tones: Aramba is in the key of C sharp, Faritia 1 is in the key of C sharp, and Faritia 2 is in the key of E.94 PagesSkripsi Sarjan

    Determinants Of Income Inequality in BRICS Countries: a Macroeconomic Perspective

    No full text
    Income inequality remains a structural issue in developing economies, including BRICS countries (Brazil, Russia, India, China, and South Africa). Despite their strong economic growth, these nations continue to experience uneven income distribution. This study examines the macroeconomic determinants of income inequality in BRICS countries during the 1993–2022 period. The dependent variable is income inequality measured by the Gini Index, while the independent variables include economic growth, urbanization, inflation, and the Human Development Index (HDI). The study employs secondary panel data obtained from the World Bank and UNDP. The analysis is conducted using panel data regression with the Fixed Effect Model (FEM), selected based on the Chow, Hausman, and Lagrange Multiplier tests. The results show that economic growth and HDI have a significant negative effect on income inequality, while urbanization and inflation have a significant positive effect. Simultaneously, all independent variables significantly influence income inequality in BRICS countries. These findings highlight the importance of inclusive economic policies, inflation control, and equitable human development to reduce income disparities within the BRICS economies.98 PagesSkripsi Sarjan

    Design of an Automatic Rainwater Drainage System on NFT Hydroponic Plants Using Microcontroller

    No full text
    Hydroponics has been widely done by the people of Indonesia. But in its application, many factors determine the success of hydroponic vegetable cultivation, including nutrients, planting media, oxygen and water. In addition to providing appropriate nutrition, there is another factor that must be considered namely rainfall. When it rains, rainwater will mix with nutrient water and this will cause nutrient water levels to decrease or disappear. So, after the rain stops, the thing to do is check the condition of the nutrient content of the water and add nutrient water to keep it by the levels needed by plants. One way that is often used to protect hydroponic plants from rainwater is to build a greenhouse. However, making a greenhouse itself requires a lot of money, the costs incurred for making greenhouse can reach millions or even tens of millions of rupian. To overcome this while saving costs, through this study, the author created an automatic rainwater disposal control system on nft hydroponic plants using a microcontroller. Where later the results of this study show that the tool will work automatically when rain comes to dispose of rainwater so that it does not mix with nutrient water in the reservoir.56 PagesSkripsi Sarjan

    Indonesia has abundant energy resources, one of which is nypa fruit husk biomass (Nypa fruticans W.) that can be utilized as a raw material for renewable energy production. This study aimed to examine the effect of condenser pipe diameter variation on a multiple-condenser pyrolyzer system using nypa fruit husk biomass. The research was conducted using a factorial Completely Randomized Design (CRD) with two factors, namely condenser pipe diameter (3/8 inch; 4/8 inch; and 5/8 inch) and pyrolysis temperature (300°C, 350°C, and 400°C), with three replications for each treatment. The observed parameters included effective capacity of the tool, energy consumption, yield, and economic analysis consisting of production cost of liquid smoke, Break Even Point (BEP), Net Present Value (NPV), and Internal Rate of Return (IRR). The results showed that the 4/8 inch condenser pipe diameter at 400°C was the most optimal treatment, producing an effective capacity of 0.68 liters/hour and a yield of 68%. The highest energy consumption was obtained at the 5/8 inch condenser pipe diameter and 400°C, amounting to 276,672.8 kJ/kg. The economic analysis indicated a liquid smoke production cost of IDR 40,485.03 per liter and a BEP of 371.62 liters/year. The NPV value reached IDR 318,206,840/year and the IRR was 44.93%, indicating that the equipment was feasible to operate and remains profitable.90 PagesSkripsi Sarjan

    Legal Protection for Consumers Suffering Losses caused by Unlawful Acts Commited by Wedding Organizers (Study of Decision No. 898/Pdt.G/Pn Jkt.Sel)

    No full text
    Wedding organizers are business entities that provide services to assist in organizing wedding receptions based on a service lease agreement between the prospective bride and groom and the wedding organizer. This research addresses three main issues: first, the form of unlawful acts committed by wedding organizers that cause losses to consumers; second, the forms of preventive and repressive legal protection for consumers who suffer losses due to such unlawful acts; and third, the analysis of judges’ considerations and decisions regarding consumer legal protection in cases of unlawful acts committed by wedding organizers based on Decision Number 898/PDT.G/2020/PN South Jakarta. This study employs a normative legal research method with a descriptive nature. The approaches used include the statutory approach and the case approach. Data were collected through library research by systematically analyzing primary, secondary, and tertiary legal materials, with qualitative data analysis using a deductive method. The results of the study indicate that the refusal of the wedding organizer to refund the consumer’s payment constitutes an unlawful act. This is due to the service lease agreement being null and void as a result of force majeure and the existence of standard clauses that violate consumer protection laws. As a consequence of the agreement being null and void, the legal situation must be restored to its original condition, whereby the funds received by the wedding organizer must be returned to the consumer.113 PagesSkripsi Sarjan

    No full text
    Introduction:Olfactory dysfunction in chronic kidney disease patients indicates neurological disorders in uremic conditions that increase in prevalence along with the severity of kidney disease. Indoxyl sulfate is a uremic toxin known to contribute to the worsening of kidney disease. Curcumin plays an important role in preventing disease pathogenesis due to its ability as an effective scavenger for ROS or reactive oxygen species; curcumin also promotes the growth and viability of olfactory ensheathing cells in normal and hypoxic conditions. Method: This study is preliminary research because there is still very rare research on this topic, conducted on 48 patients with stage 5 chronic kidney disease on regular hemodialysis who were divided into three groups: control group, 500 mg curcumin, and 1000 mg curcumin. They were given curcumin extract for 12 weeks. Plasma indoxyl sulfate levels and then their olfactory function was checked. Bivariate and multivariate tests were conducted to compare the results before and after treatment. Results: There were significant differences in olfactory discrimination delta (p=0.001) and olfactory function delta (p=0.002) in the 1000 mg curcumin group and the 500 mg curcumin group.There were significant differences in olfactory identification before and aftertreatment in the 1000 mg curcumin olfactory group (p=0.006), delta identification (p=0.618), as well as significant differences in IS levels in the 500 mg curcumin group (p=0.008) and the control group (p=0.019); delta IS level (p=0.870). There was no significant difference in olfactory threshold in the three study groups (p=0.636). Conclusion: Olfactory dysfunction in chronic kidney disease patients improved with the administration of curcumin, and no worsening of indoxyl sulfate levels was found, indicating that curcumin can stabilize the toxin.131 PagesTesis Magiste

    Framing Analysis of News Coverage on the Naturalization Process of Indonesia's Senior National Football Team Players in the 2026 World Cup Qualification Round 3 on Detik.com Online Media

    No full text
    This study aims to explore how the online media Detik.com frames the news coverage related to the naturalization process of players for the Indonesian national football team during the 2026 World Cup Qualification Round 3. The research employs a qualitative approach using Robert N. Entman’s framing analysis model, which consists of four elements: define problems, diagnose causes, make moral judgement, and treatment recommendations. The researcher analyzed 26 news articles published in the detikSport section under the Football channel during the period of September to November 2024. The findings show that Detik.com tends to frame the issue of naturalization positively, portraying it as part of a strategic effort to strengthen and improve the performance of the national team. However, the media also provides space for criticism and balanced perspectives, particularly in reporting administrative challenges and statements from coaches and football officials. Through the repetition of key themes, selected quotations from authoritative figures, and the use of national symbols, the media contributes to shaping public perception of naturalization as a legitimate, professional, and hopeful move for Indonesian football.178 PagesSkripsi Sarjan
