Analisis Efek Multiplier Sektor Basis Terhadap Perekonomian Kabupaten Biak Numfor 2019-2023

This study aims to identify base sectors and analyze the magnitude of the multiplier effect of these sectors on the economy of Biak Numfor Regency during the 2019–2023 period. The study employs a quantitative approach using secondary data in the form of Gross Regional Domestic Product (GRDP) of Biak Numfor Regency and Papua Province. The analysis applies the Location Quotient (LQ) method to determine base and non-base sectors, as well as multiplier effect analysis to measure the impact of base sectors on the regional economy. The results indicate that there are nine base sectors, namely agriculture, forestry and fisheries; mining and quarrying; manufacturing; electricity and gas supply; water supply and waste management; trade; transportation; financial services; and government administration. Meanwhile, eight sectors are classified as non-base sectors, including construction; accommodation and food services; information and communication; real estate; business services; education; health services; and other services. The average multiplier effect value of 1.3059 implies that every one-unit increase in base sector output contributes to an increase in total regional economic output. However, the declining trend of the multiplier effect during the 2020–2023 period indicates weak linkages between base and non-base sectors. Therefore, local governments need to promote the development of fishery-based processing industries and enhance the capacity of non-base sectors, particularly construction, education, and health services, in order to optimize the multiplier effect and support regional economic growth.    Keywords:  Multiplier effect, base sector, non-base sector, Location Quotient, GRDP, Biak Numfor Regency, regional economic growt

Analisis Pengaruh Investasi dan Pengeluaran Pemerintah Terhadap Ketimpangan Pendapatan di Kota Jayapura

The influence of investment and government spending on income inequality in Jayapura City from 2016 to 2023. The research method used was multiple linear regression. The analysis results showed that investment actually has a significant negative impact on income inequality. This finding indicates that the benefits of investment are felt more by high-income groups, thus widening the gap between the rich and the poor. Meanwhile, low-income groups experience a wider gap due to the inequity in the allocation of investment benefits. On the other hand, government spending has been shown to make a significant positive contribution to increasing the income of low- and middle-income groups. Through social programs and appropriate budget allocation, government spending helps improve the standard of living of these groups and thus can reduce income inequality. These findings suggest that inclusive and welfare-oriented government policies can be an effective tool in addressing inequality issues. This study highlights the importance of the government\u27s role in formulating policies that not only encourage investment but also ensure that the benefits of such investment are felt by all levels of society. Therefore, increasing budget allocations for social programs and equitable infrastructure development is essential to create a better balance in income inequality.

PROBLEMATIC ANALYSIS OF SCIENCE LEARNING PROCESS

This study aims to thoroughly analyze the problems encountered in the Natural Science (IPA) learning process at SMP Negeri 1 Suwawa Timur, considering the 21st-century curriculum demands that require the development of students\u27 scientific attitudes and skills through direct experience. This research employs a descriptive qualitative approach, where data was collected through a closed questionnaire administered to 32 students of class IX A and in-depth interviews with the IPA subject teacher. The analysis results identified two major interconnected issues: (1) lack of teacher competence and strategies, and (2) sub-optimal utilization of school facilities and infrastructure. The low student learning motivation was confirmed by the teacher as a crucial obstacle, which ironically occurs despite the school having complete laboratory facilities. The root problem was found in the lack of teacher knowledge and professional competence in operating and utilizing laboratory equipment for practical activities. It is concluded that the minimal implementation of practical work due to limitations in teacher competence is the main factor contributing to low student motivation and learning achievement. Therefore, this study recommends the necessity of continuously enhancing teacher competence related to laboratory facility utilization to optimize the quality of the IPA learning process in the school

CLUSTERING KABUPATEN/KOTA DI PROVINSI PAPUA BERDASARKAN INDIKATOR KEMISKINAN MENGGUNAKAN METODE K-MEDOIDS

Badan Pusat Statistik (BPS) telah merilis berbagai variabel terkait informasi kemiskinan tingkat kabupaten/kota di Indonesia pada tahun 2020. Angka kemiskinan tiap kabupaten/kota di Indonesia berbeda-beda. Perbedaan ini disebabkan oleh banyak indikator yang berbeda seperti: indeks pembangunan manusia, angka penduduk, pendapatan per kapita, angka melek huruf, akses terhadap pendidikan, akses terhadap air bersih dan kualitas yang cukup, dll. Sehingga digunakan metode clustering K-Medoids untuk mengelompokkan berdasarkan indikator-indikator tersebut. Algoritma K-Medoids merupakan salah satu metode clustering yang diusulkan untuk mengatasi kelemahan algoritma K-Means yang sensitif terhadap outlier karena suatu objek dengan nilai yang tinggi dapat menyimpang secara signifikan dari sebaran datanya. Algoritm K-Medoids menggunakan data alih-alih merata-ratakan pusat cluster. Dengan menggunakan analisis K-Medoids diperoleh cluster optimal sebanyak 2 cluster yang dikategorikan sebagai Kabupaten/Kota dengan indikator kemiskinan sedang dan tinggi dari 29 kabupaten/kota, dimana pada cluster 1 dengan 17 Kabupaten/Kota tergolong kemiskinan tinggi karena pada cluster ini Indeks Pembangunan Manusia dan Laju Pertumbuhan PDRB tergolong rendah dan Persentase Penduduk Miskin tinggi. Untuk cluster 2 dengan 12 Kabupaten/kota tergolong kemiskinan sedang karena pada cluster ini Indeks Pembangunan Manusia dan Laju Pertumbuhan PDRB tinggi sedangkan Persentase Penduduk Miskin rendah

Upaya Peningkatan Kemampuan Geometri Siswa SMP ST. Antonius Padua Sentani Melalui Pendekatan Matematika Realistik

Conceptual understanding is central to geometry learning, yet many junior high school students find geometric objects and their properties highly abstract. This community service program was conducted at SMP St. Antonius Padua Sentani, Jayapura Regency to strengthen Grade VIII students’ understanding of plane and solid geometry through a Realistic Mathematics Education (RME) approach. The program used context-based problems, concrete manipulatives, guided discussions, and structured practice. Program effectiveness was evaluated using a one-group pretest-posttest design (n=20). The mean score increased from 34 (pretest) to 41 (posttest) with an N-gain of 0.11 (low). Although the learning gains were modest, the activities improved student engagement and supported the transition from contextual situations to formal geometric representations. The results suggest that continued implementation and repeated cycles of RME-based instruction with richer tasks and longer duration are needed to achieve stronger learning gains

Identification of parasites in goatfish (Upeneus sp.) sold at Asem Traditional Market, Surabaya, Indonesia

Goatfish (Upeneus sp.) is a marine fish commonly sold in traditional markets and widely consumed by the community. However, fish sold in markets may carry parasites that can potentially pose health risks to consumers. Therefore, parasite identification is necessary to provide information regarding parasite occurrence in marketed fish. In this study, eight goatfish samples obtained from the Asem Traditional Market, Surabaya, Indonesia, were examined using macroscopic and microscopic methods. The results showed that 37.5% of the samples were infected with Anisakis sp., with a total of 15 larvae and an average intensity of five larvae per infected fish. The larvae were found in the digestive organs and exhibited distinctive morphological characteristics, including a boring tooth on the anterior end and a mucron on the posterior end, which support the parasite’s invasive ability. These findings indicate a potential health risk to consumers, particularly if the fish is consumed raw or undercooked. Prevention can be achieved through proper post-harvest handling and adequate cooking temperatures to ensure the larvae become non-infective
