The Effectiveness of the Land and Building Tax Revenue System in Optimising Regional Original Income in Serdang Bedagai Regency
No full textThe Financial Capacity of Regions, Particularly Local Own-Source Revenue
(PAD), as a Key Challenge in Development and Public Services. Local taxes and
levies, such as Land and Building Tax (PBB), are key components of PAD.
However, PAD realization in Serdang Bedagai Regency remains fluctuating, with
PBB contributions dominated by toll road taxes. This inconsistency in PBB
realization stems from late tax payments, an insufficient number of tax officers
relative to the region's vast area, and a non-integrated manual system. This study
aims to analyze the effectiveness of the Land and Building Tax (PBB) collection
system as a primary component of PAD in Serdang Bedagai Regency. Using a
qualitative descriptive method, data was collected through observation, document
studies, and in-depth interviews with purposively selected informants, including
Bapenda (Regional Revenue Agency) staff, taxpayers, and related stakeholders.
The findings indicate that PBB contributes 30-40% of PAD, with an average annual
revenue growth of 12% post-pandemic. This increase is driven by updates to
taxpayer data, digital payment systems, adjustments to the Tax Object Sales Value
(NJOP), and inter-institutional collaboration. Digital transformation, such as
online payment applications and Geographic Information System (GIS)
integration, has improved PBB collection efficiency and accuracy. However,
challenges persist, including uneven taxpayer awareness, limited technological
access in remote areas, and dynamic property data changes. Employee motivation
factors have contributed to a 20% productivity increase and 98% employee
attendance. Taxpayer compliance is influenced by digital payment convenience,
incentives, and transparency in tax fund allocation, though public resistance
remains. The study recommends strengthening the tax database, improving human
resource capacity, expanding digital infrastructure, and adopting inclusive
approaches for remote communities to ensure PBB becomes a stable and equitable
PAD source. Policy implications emphasize balancing digital transformation with
a human-centric approach to create an effective, fair, and sustainable regional tax

Study of Distribution Pattern of State Educational Facilities in Sei Rampah District Serdang Bedagai Regency
No full textAccess to education is recognized as a fundamental right for all Indonesian citizens. The quality of education can be improved by ensuring affordable educational facilities are available to every citizen. In Sei Rampah district, Serdang Bedagai regency, there are significant disparities in the distribution of educational facilities. A study was conducted to analyze the distribution pattern of these facilities, assess the need for additional facilities, and determine the accessibility of existing facilities. The research was conducted using a descriptive quantitative method, with data analysis involving nearest neighbor analysis and spatial analysis using GIS. The results show that the distribution pattern of public schools in Sei Rampah District is quite diverse, where public primary schools have a random pattern, public junior high schools have a uniform pattern and public senior high schools and vocational schools have a clustering pattern. Regarding the need for educational facilities for the next 10 years (2033) based on population, it is identified that primary schools require 11 public primary schools, junior high schools require 4 public junior high schools. Meanwhile, senior high schools need 5 public senior high schools and vocational high schools need 4 public vocational high schools in order to meet the needs of schools based on population. In addition, the results also show that the average area of coverage distance for public schools are Near and Medium, which means that students can reach their schools within 5-20 minutes on foot. However, for Public senior high schools and vocational high schools, due to the unmet need for schools as well as the clustered pattern of school distribution, these schools cannot accommodate students in all urban villages in Sei Rampah so that potentially these students attend schools in the nearest district.135 PagesTesis Magiste

enhancing operational efficiency in pineapple processing applications.57 PagesSkripsi Sarjan
Analysis of Supplier Relationship Performance and Supplier Relationship Improvement Using the DMAIC Method at PT. Ujang Jaya International
No full textCoffee is one of Indonesia’s main export commodities, contributing significantly to national foreign exchange earnings. The majority of coffee supply comes from smallholder farmers across various regions. PT. Ujang Jaya International, a coffee exporting company, faces challenges in maintaining supply stability due to informal and unstructured relationships with its suppliers. This condition leads to fluctuating supply and weakens the company’s export competitiveness. This study aims to evaluate the supplier relationship using the Supplier Relationship Performance Measurement (SRPM) approach, which includes six key variables: trust, bargaining power, transparency, communication, commitment, and sustainability. Additionally, the study proposes improvement plans using the DMAIC method (Define, Measure, Analyze, Improve, Control). Data were collected through questionnaires distributed to both the company and suppliers, supported by in-depth interviews for validation. The findings indicate that the quality of the relationship is at a moderate level, with significant weaknesses in commitment and bargaining power. Recommended improvements include the implementation of formal contracts, enhanced communication and transparency, and performance-based incentives. These steps are expected to foster a more sustainable and competitive partnership in the global coffee supply chain.118 pagesTesis Magiste
