Description of the Technique of Making and Playing Techniques 0f Uyup-Uyup Musical Instruments by Mr. Marito Lintang in Huta Dolok Village, Pakantan District, Mandailing Natal Regency
No full textUyup-uyup is a traditional musical instrument that represents the cultural heritage of the Mandailing community. It is made from rice stalks (batang ni eme) wrapped with young coconut leaves shaped like a cone, which serve as the resonator. This instrument holds a social function as a source of entertainment for farmers during their rest periods in the rice fields, particularly during the harvest season. This study aims to provide an in-depth description of the manufacturing process and playing techniques of the uyup-uyup instrument. The research employs a qualitative descriptive method through observation, interviews, documentation, fieldwork, and laboratory analysis. The theoretical framework is based on Khasima Susumu’s structural and functional approach, as well as the musical instrument classification system according to Curt Sachs and Erich M. von Hornbostel. The findings indicate that the process of making the uyup-uyup includes several stages: material selection, tool utilization, component measurement, shaping, and the final finishing stage to produce a precise
instrument. The basic playing technique involves blowing through the mouth to produce sound, accompanied by fingering techniques to open and close the resonator holes to create tonal
variations. Based on the Sachs-Hornbostel classification system, the uyup-uyup is categorized as a multi-reed aerophone, as its sound is produced by air vibration passing through multiple
reed openings within a single instrument.83 PagesSkripsi Sarjan
Instagram Content Marketing Strategy to Increase Sales on the Shopee E-Commerce Platform (A Case Study on USU-Assisted MSME: Hael Beaute)
No full textThis study examines use of Instagram content marketing strategies to increase sales on the Shopee e-commerce platform, with a case study of Hael Beaute, a USU-assisted MSME in Indonesia's beauty sector. The research focuses on declining customer engagement on Instagram.This issue persists despite Hael Beaute’s large follower base (over 25,000) and inconsistent sales performance between October 2024 and January 2025. The purpose of this research is to analyze the existing Instagram content marketing strategy, identify its challenges, and propose optimal improvements to enhance engagement and drive conversion on Shopee. This research employs a qualitative case study approach, using in-depth interviews with Hael Beaute’s management team and thematic analysis to examine current content strategies. The SOAR framework (Strengths, Opportunities, Aspirations, Results) was used to identify strategic recommendations. Data on sales transactions and Instagram engagement metrics were triangulated to validate findings.The results reveal that Hael Beaute’s Instagram marketing relied heavily on organic strategies with limited posting frequency. It lacked consistent scheduling, which contributed to a 96% drop in engagement between December 2024 and February 2025. Proposed optimizations include structured content calendars, use of engaging formats like Reels and Stories, improved call-to-action design, collaboration with micro-influencers, and paid amplification strategies. Systematic Instagram content marketing, when tailored to specific audience goals, can transform Instagram into an effective sales funnel for MSMEs like Hael Beaute.231 pagesTesis Magiste
The Art of The Serdang Sultanate in The Sociopolitical Currents from The Colonial Period to The Early Days of The Republic of Indonesia (1900-1946)
No full textThis study analyzes the role of the arts, specifically music, dance, and
sendratasik (a composite art form of drama, dance, and music), within the
Serdang Sultanate in response to the sociopolitical dynamics of the 1900–1946
period. Within this framework, the arts are not understood merely as aesthetic
expressions but rather as strategic responses to the challenges of their time. The
Sultanate's elite and artists, under the leadership of Sultan Sulaiman Syariful
Alamsyah, deliberately utilized the arts as a form of soft power and a cultural
instrument to convey messages of resistance, strengthen collective identity, and
awaken consciousness to fight for communal rights. This research identifies and
analyzes several artistic works that emerged during a critical period marked by
Dutch colonial hegemony, Japanese occupation, and the lead-up to the
proclamation of Indonesian independence. These works served a dual function:
not only fulfilling an aesthetic purpose but also acting as a medium for social
communication, an expression of resistance, and a tool for negotiating the
community's collective identity. The analysis is focused on three primary
examples: the song Mahkota Negara (Crown of the State), which functioned as a
"national anthem" to consolidate patriotism; the Serampang Dua Belas Dance, as
a creative adaptation effort to affirm a modern and dignified Malay image; and
the sendratasik Mak Yong, as a medium for cultural resistance against
'misrecognition'—defined here as the denial, distortion, or misjudgment of identity
or rights, which negatively impacted dignity, autonomy, and social justice.
Employing a qualitative narrative method, along with the theoretical framework
of C.A. Van Peursen's Cultural Strategy, Pierre Bourdieu's Theory of Agency in
Cultural Practice, and Nancy Fraser's concept of 'Recognition', this study reveals
several art forms born from the background of sociopolitical conditions or
dynamics. Furthermore, it highlights the role of the Serdang Sultanate's elite and
artists who actively actualized their agency to maintain the integrity and
sovereignty of their state amidst power struggles.172 PagesTesis Magiste
Correlation between QRS Complex Duration and Left Ventricle Ejection Fraction in Acute Heart Failure Patients Based with Fragmented QRS on Electrocardiography Finding at Rumah Sakit Adam Malik Medan
No full textIntroduction. Heart failure is a clinical syndrome caused by ventricular dysfunction or
structural abnormalities, affecting 1–3% of adults globally, with higher prevalence in
those over 65. In Asia, there are around 721,100 cases, with 5% in Indonesia. Based on
LVEF, it is classified into HFrEF, HFmrEF, and HFpEF. Fragmented QRS (fQRS) on
ECG indicates myocardial damage and reduced LVEF. Indonesian studies highlight
fQRS in assessing myocardial injury and heart failure severity. This study analyzed the
relationship between QRS duration and LVEF in patients with heart failure at Adam
Malik Hospital Medan.
Method. A cross-sectional study was conducted at Adam Malik Hospital Medan from
January-December 2023. Participants were selected through consecutive sampling,
meeting inclusion criteria of acute heart failure diagnosis and documented LVEF, while
those with pacemakers, defibrillators, or acute myocardial infarction were excluded. Data
were analyzed using SPSS 26, with Spearman test for correlation of QRS duration and
LVEF. A Cardiovascular Consultant evaluated the fQRS data for accuracy.
Result. Heart failure patients at Adam Malik General Hospital had a mean age of 53,25 ±
12,02 years, with 60,5% male. fQRS duration ranged from 80–180 ms in the fQRS (+)
group and 78–110 ms in the fQRS (-) group. LVEF <50% was found in 55,6% of
patients, while 44,4% had LVEF ≥50%. A weak negative association existed between
QRS duration and LVEF (r = -0,255, p = 0,021).
Conclusion: The QRS complex duration was found higher in group with fQRS (+)
compared to fQRS (-). A weak negative correlation was found between QRS duration and
LVEF.93 pagesTesis Magiste
The Relationship between VAL66MET Polymorphism of the Brain-Derived Neurotrophic Factor (BDNF) Gene and Restless Leg Syndrome in Patients with Chronic Kidney Disease Undergoing Regular Hemodialysis
No full textBackground: Restless Legs Syndrome (RLS) is a common sensorimotor disorder
among patients with chronic kidney disease (CKD) undergoing hemodialysis.
Genetic factors, including the Val66Met polymorphism of the Brain-Derived
Neurotrophic Factor (BDNF) gene, are suggested to contribute to RLS pathogenesis
through impaired neuroplasticity and dopaminergic dysfunction. However, such
associations have not been extensively studied in the Indonesian population.
Objective: To investigate the association between the Val66Met polymorphism of
the BDNF gene and the occurrence of RLS in CKD patients undergoing regular
hemodialysis.
Methods: This case-control study included 70 DNA samples from CKD patients at
Rasyida Kidney Hospital, Medan—35 with RLS and 35 without. Genotyping was
performed using the PCR-RFLP method. Statistical analyses included Chi-Square
and logistic regression tests with a significance level of p < 0.05.
Results: Most subjects were over 40 years old (95.7%) and female (60%). The
Val66Met genotype distribution was dominated by Val/Met (50%), followed by
Val/Val (37.1%) and Met/Met (12.9%). The Val allele was found in 62.14% and
the Met allele in 37.85% of subjects. The Val/Met genotype showed a significant
association with RLS (p < 0.001; OR = 7.333; 95% CI = 5.221–146.968).
Multivariate analysis confirmed that age (p = 0.001; OR = 1.482; 95% CI = 1.333–
1.570) and BDNF polymorphism (p = 0.001; OR = 7.375; 95% CI = 4.392–12.837)
were significant predictors of RLS, while sex and anemia were not statistically
significant.
Conclusion: The Val66Met polymorphism of the BDNF gene—particularly the
Val/Met genotype—is significantly associated with increased risk of RLS among
CKD patients undergoing regular hemodialysis. These findings support the
potential role of BDNF as a genetic biomarker in the pathophysiology and
management of RLS in chronic kidney disease populations.
Keywords: Chronic kidney disease, hemodialysis, BDNF, Val66Met
polymorphism, Restless Legs Syndrome.68 PagesTesis Magiste

Binary Probit Regression Method For Analyzing Factors Affecting The Likelihood Of High Income Inequality(Gini Ratio) In North Sumatera Province
No full textIncome inequality is a critical issue in economic development and is often
measured using the Gini Ratio. This study aims to analyze the factors that influence
the likelihood of high income inequality in North Sumatra Province in 2024. The
method used is binary probit regression, with the dependent variable being the Gini
Ratio category (high > 0.30 = 1, low ≤ 0.30 = 0), and the independent variables
include the Open Unemployment Rate (TPT), education, economic growth rate, and
poverty level.The data used are secondary data from the Central Bureau of
Statistics (BPS), covering 33 districts/cities in North Sumatra. The results show that
only the variable of economic growth has a significant effect on the likelihood of
high income inequality, with a p-value of 0.036. The marginal effect analysis also
shows that a 1 percent increase in economic growth can reduce the likelihood of a
region experiencing high inequality. The binary probit regression model used has
a classification accuracy rate of 87.88% and is considered a good fit based on the
goodness-of-fit test (Prob > chi² = 0.7645). Overall, this study concludes that
inclusive economic growth is crucial in reducing inequality. These findings can
serve as a basis for formulating equitable development policies across regions in
North Sumatra.63 pagesKertas Karya Diplom

Public Political Behavior in the Village Head Election: A Case Study of Bandar Setia Village, Percut Sei Tuan District, Deli Regency, Serdang, 2022
No full textThis study examines the political behavior of the community in the village head
election held in Bandar Setia Village, Percut Sei Tuan Sub-District, Deli Serdang
Regency, in 2022. The main problem explored is how the community‘s voting
behavior takes shape and what factors influence it during the village head election
process. The aim of this research is to understand the political orientations of
village residents and the social dynamics that affect their political decisionmaking. The method used is qualitative descriptive, with data collected through
observation, in-depth interviews, and documentation. The results show that the
political behavior of the community tends to be influenced by affective and
evaluative orientations, such as emotional closeness, kinship ties, the influence of
local figures, and traditional loyalties, rather than rational considerations of the
candidates‘ visions, missions, or work programs. This phenomenon indicates that
the village head election is not merely a formal electoral process but also a social
arena rich in local cultural values. This study recommends the need for continuous
political education at the village level so that community participation becomes
more rational and focused on the quality of leadership.138 PagesSkripsi Sarjan
