Abstract

This paper discusses some of the terminology and basic properties of the set of min-plus algebra symmetrization. The results are algebraic structure of the positive or zero part of the set of min-plus algebra symmetrization is a semi-field, and the min-plus algebra can be viewed as the positive or zero part in the context of the set of min-plus algebra symmetrization. Furthermore, the form of the result of the subtraction of the elements in the set of min-plus algebra symmetrization, the multiplicative inverse of element in the non zero-positive and negative part, and some basic properties of balance as an analogy to the similarity of linear algebra are also obtained.

Abstract

Bank Syariah Indonesia was inaugurated on February 1, 2021, which is a combination of BNI Syariah, Mandiri Syariah, and BRI Syariah. One of the ease of transaction facilities for customers is using an ATM (Automated Teller Machine). BSI currently has 18,291 ATMs spread throughout Indonesia and 10 of them are located in Jember Regency. The purpose of the ATM is to increase customer convenience and public trust in BSI. Ease of access to ATMs will affect the number of customers because ATM locations that are easily accessible can increase the number of profits obtained by BSI. The main factors in determining the location of ATMs that need to be considered are easy to reach, close distances, and safe locations. The Fuzzy C Means (FCM) method is used to classify the right area in determining the location of ATMs. The results of this study, the Jember district can be grouped into 6 clusters, wherein each cluster there is one ATM with the first cluster and the sixth cluster with as many as 9 districts, the second cluster with as many as 6 districts, the third cluster as many as 5 districts, the fourth cluster as many as 7 districts, and the fifth cluster as many as 4 districts. The conclusion of this study, is the exact location of BSI ATMs in Jember Regency based on the number of clusters that have been determined to be in Patemon Village, Antirogo Village, Jubung Village, Jember Lor Village, and Sumbersari Village. Clustering validation uses the Silhoutte Index (SI) with an average silhouette coefficient of 0.83028.

Abstract

This article discusses Zillmer's reserves for endowment life insurance. Zillmer reserves are a type of modification of premium reserves which are calculated using prospective reserves and the Zillmer rate. In Zillmer reserves, loading which is the difference between gross premium and net premium in the first policy year is greater than standard loading, so the purpose of this research is to find a way to make the loading smaller. To achieve this goal, this article uses the Pareto distribution and the Cox-Ingersoll-Ross (CIR) interest rate model. Based on the illustration, even though in the first policy year there was still a negative loading, however, Zillmer's reserves have been increasing from time to time since the second policy year.

Abstract

This study aims to examine the conditions of, and formulate a strategy for, developing smoked fish processing in small and medium enterprises (SMEs) in Bone Regency. Methods of data collection include interviews, field observations, and documentation with questionnaires. Method of data analysis include descriptive analysis of the conditions and characteristics of smoked fish processing SMEs, SWOT (Strength-Weakness-Opportunities-Threat) analysis and QSPM (Quantitative Strategic Planning Matrix) methods to formulate priority strategies for developing smoked fish processing SMEs. The results show the following conditions of smoked fish processing in Bone Regency: 100% of the SMEs use simple technologies, 79% have low education, 91.94% of the workforce was of productive age. The SMEs development strategies that can be learned include strategies for establishing cooperative relationships and government support in promoting smoked fish processed products, strategies for developing smoked fish processing SMEs with training and counseling programs from relevant agencies, strategies for implementing the latest processing technological innovations by renewing infrastructures of facilities, as well as strategies for completing business permits and legalities.Penelitian ini bertujuan untuk mengkaji kondisi dan merumuskan strategi pengembangan Usaha Kecil dan Menengah (UKM) pengolahan ikan asap di Kabupaten Bone. Pengumpulan data dilakukan dengan wawancara, observasi lapangan, dan dokumentasi dengan kuesioner sebagai alat bantu.  Analisis dilakukan secara deskriptif terhadap kondisi dan karakteristik UKM pengolah ikan asap. Analisis iSWOT dan metode QSPM untuk merumuskan prioritas strategi pengembangan UKM pengolahan ikan asap. Hasil penelitian menunjukan bahwa kondisi pengolah ikan asap di Kabupaten Bone 100% menggunakan teknologi sederhana, 79% memiliki pendidikan rendah, serta umur tenaga kerja produktif sebanyak 91,94% dan strategi pengembangan UKM yang dapat di ambil adalah strategi menjalin hubungan kerjasama dan dukungan pemerintah dalam mempromosikan produk olahan ikan asap, strategi peningkatan/pengembangan UKM pengolahan ikan asap dengan program pelatihan dan penyuluhan dari dinas terkait, strategi penerapan inovasi-inovasi teknologi pengolahan terkini dengan pembaharuan sarana prasarana, serta strategi penyelesaian perizinan dan legalitas usaha.

Abstract

Population data is one of the absolute requirements that must be fulfilled by the Central Statistics Agency (Badan Pusat Statistik) to determine the grand design of development in the Province of Papua. However, the most complete and accurate source of population data comes from the results of a population census carried out every ten years. With long intervals and requiring costs, time, and effort, it will be more efficient and save time and effort if the number of residents can be estimated. Estimating the population required the proper method. Therefore, in this article, a comparison of Forward Newton-Gregory Polynomial Interpolation and Backward Newton-Gregory Polynomial Interpolation techniques is carried out to estimate the population of Papua Province. The estimated results of the two methods are compared by comparing the relative amount of error. The comparison results show that the relative error average of the Forward Newton-Gregory Polynomial Interpolation 0,014200679 is smaller than the relative error average of the Backward Newton-Gregory Polynomial Interpolation 0,047163677. So, it can be concluded that the Forward Newton-Gregory Polynomial Interpolation method is better than Backwards Newton-Gregory Polynomial Interpolation in predicting the population of Papua Province.
