Abstract

Perlu kita ketahui bersama bahwa setiap aspek pelayanan administrasi dapat diketahui tingkat kepuasaan kinerja salah satunya pelayanan administrasi kependudukan untuk melayani masyarakat. Berdasarkan penelitian ini penulis dapat mengetahui aspek pelayanan yang menjadi prioritas untuk ditingkatkan melalui nilai gap yang diperoleh dalam perhitungan. Gap analysis adalah metode pengukuran untuk mengetahui kesenjangan antara kinerja dari suatu variabel dengan harapan pengguna layanan terhadap variabel tersebut. Penelitian ini, penulis menggunakan Metode fuzzy service quality untuk menganalisa kepuasan pelayanan administrasi kependudukan serta menggunakan Metode Importance Performance Analysis untuk mengukur hubungan antara persepsi pengguna layanan dan prioritas peningkatan kualitas pelayanan administrasi kependudukan. Dalam Metode Importance Performance Analysis terdapat 2 perhitungan dalam menentukan gap analysis yaitu mencari tingkat kesuaian dan diagram kartesius. Hasil dari proses perhitungan menunjukkan bahwa ada indikator-indikator yang harus dilakukan perbaikan atau peningkatan layanan administrasi kependudukan sesuai dengan prioritasnya.

Abstract

The dynamic development of socio-economic conditions, accompanied by increasing household needs and income uncertainty, requires communities to possess sound and sustainable financial management capabilities. Women, particularly housewives and micro-enterprise actors, play a strategic role in managing household and business finances. However, limited understanding of financial planning, investment, and insurance remains a major challenge that may increase vulnerability to financial risks. One strategic measure to strengthen household economic resilience is the enhancement of financial literacy through targeted and contextual education, especially regarding the introduction of investment and insurance as instruments for financial planning and risk protection. This community service program aims to improve women’s financial literacy through educational activities focusing on the basic principles of investment and insurance, as well as their application in the context of entrepreneurship and household financial management. The target participants are members of the PKK Women’s Group in Sidawung Hamlet, Kali Gading Village, Boja Subdistrict, Kendal Regency. The implementation methods include interactive lectures, simple demonstrations, discussions based on local case studies, and evaluation through pre–post tests. Indicators of program success include improvements in participants’ financial literacy scores, enhanced understanding of investment and insurance concepts, and increased motivation to adopt regular saving habits, maintain business financial records, and consider appropriate simple investment instruments and insurance products. The expected outcomes of this program are improved basic financial literacy knowledge and skills, as well as the development of follow-up action plans by the PKK group related to financial management and risk protection for family-based enterprises.

Abstract

Economic growth serves as a key factor in analyzing the economic conditions of a country or region. The secondary panel data used in this study consists of a combination of cross-sectional data from five regencies/cities in East Nusa Tenggara (NTT) that were most affected by the COVID-19 pandemic. This time-series data spans from 2018 to 2023 and is split into three phases: the period before the pandemic, the pandemic period, and the post-pandemic period.This study aims to analyze the factors influencing economic growth in NTT Province during the pre-, during-, and the period after the pandemic. The research employs the Fixed Effect Model (FEM) with Gross Regional Domestic Product (GRDP) as the dependent variable. The independent variables include the Regional Minimum Wage (UMR), Per Capita Expenditure, Labor Force Participation Rate (TPAK), and Domestic Investment (PMDN). The research findings indicate that the variables that significantly influence economic growth in NTT Province are the Regional Minimum Wage and Per Capita Expenditure. The Regional Minimum Wage has a negative impact on economic growth, whereas Per Capita Expenditure has a positive impact. This means that an increase in the Regional Minimum Wage will decrease economic growth, while an increase in Per Capita Expenditure will enhance economic growth.

Abstract

The open model as the one the application of Leontief model using the explanation of the economy with input-output model. The open model shows the number of productions needed to satisfy an increase in internal and external demand. By using the operation linear algebra operation on ring characteristics, then the production numbers are calculated. This method is applied on the ten product-producing commodities of North Sumatera export demand to find the total production number, while the amount of demand is defined. It shows a solution to the minimization linear program is the solution that will satisfy both internal and external demands of the commodity with minimum inventory level.
