Abstract

The importance of good amil governance in zakat management becomes increasingly urgent along with the complexity and size of the funds being managed. Practices involving transparency, accountability, responsibility, independence, fairness, and legal compliance are the keys to success in achieving efficiency and effectiveness in zakat management. Therefore, it is necessary to carry out further description and exploration regarding the concept of good amil governance based on zakat core principles. This research is a literature study that adopts a descriptive-exploratory qualitative approach. Secondary data sources were obtained from various literature, including journal articles, books, official reports from the BAZNAS Study Center, and government documents, as well as other relevant sources. The Systematic Literature Review (SLR) technique was utilized to optimize the data, which was then analyzed in depth using a descriptive-exploratory qualitative approach to present a comprehensive picture of the concept of good amil governance according to zakat core principles.

Abstract

Mathematics is a field of study needed in various aspects of life. Accordingly, mathematics should always be considered a compulsory subject at every level of education, including in Islamic Boarding Schools. The fact shows that implementing mathematics learning in several schools needs to run optimally, especially in schools lacking teachers and limited educational facilities and infrastructure, such as The Al Ashry Islamic Boarding School, at the secondary level in Padang. This condition indicates that it is necessary to assist other parties to help students in their mathematics learning process. For this reason, the community service team of The Mathematics and Science Data Department of Andalas University conducted an intensive mathematics tutoring activity for The Al-Asyri Boarding School students. The activity carried out during September-December 2022 combined the lecture and the small group discussion approach. From the evaluation delivered by the students at the end of the activity, it can be concluded that this activity increased students’ interest, motivation, efficacy, and understanding of mathematics subject.

Abstract

Whether or not a policy is effective can be caused by implementing factors. The implementation implementer referred to as the street bureaucracy is the link between the bureaucracy and the community. In such relationships are influenced by the culture of each. This article discusses the implementation of stunting handling in West Pasaman District, West Sumatra Province. The objectives of this article are: describe the implementation of stunting handling policies by implementers and explain the acceptance of targets to the policy implementation program. This article is based on research using qualitative methods with an ethnographic approach. The research data were collected by observation techniques and in-depth interviews. The results showed that the implementation of stunting prevention in West Pasaman has been formally carried out well. The Regional Apparatus Organization involved and the implementation officer at the spearhead are working seriously with each of their duties. This has made the Regional Government of West Pasaman Regency ranked first in the Convergence Action to Accelerate Stunting Reduction 4 times in a row from 2019 to 2022. However, people in Nagari who are the locus of stunting feel that the program approach actually makes the target community (especially those with stunting children) feel depressed and intimidated, causing resistance to posyandu activities. So it can be said that the implementation of stunting prevention carried out is less effective.

Abstract

Batam City is one of the tourist attractions in Indonesia with the number of foreign tourist arrivals increasing every year. As one of the impacts of increasing the number of foreign tourist visits, the provincial government must improve the existing facilities in the tourism area, both in quality and quantity. In order for these facilities to be adequate to serve foreign tourists visiting Batam City in the future, it is estimated that the number of tourist visits to Batam City in the future is expected. This study aims to model foreign tourist arrivals using the SARIMA method and Neural Networks and compare the accuracy of the two methods with Mean Squared Error (MSE) and Mean Absolute Percentage Error (MAPE). The best SARIMA model for data on the number of foreign tourist arrivals to Batam City is SARIMA (2, 1, 0)(1, 1, 0)12 with MSE = 2,672,774,359 and MAPE = 21,4487%. The Neural Network Model is ˆy = max(0, 0.03208266 + 0.48310924V1 +...+ 0.46732363V8) with MSE = 171.279.990 and MAPE = 7.1404%. Thus, modeling with Artificial Neural Networks in these cases provides a better model than SARIMA in modeling data on the number of tourist visits to Batam City.

Abstract

Dalam berinvestasi saham, setiap investor ingin mendapatkan return yang tinggi dan risiko yang rendah. Salah satu cara untuk meminimalisir risiko adalah dengan membentuk portofolio optimal yang menguntungkan dari segi return dan risiko. Pada penelitian ini digunakan Capital Asset Pricing Model (CAPM) dalam membentuk portofolio optimal. Data yang digunakan adalah data saham dalam Jakarta Islamic Index (JII) periode Desember 2020-November 2021. Pemodelan menghasilkan 5 saham penyusun komposisi portofolio optimal. Return eskpektasi portofolio sebesar 0,015282 dan risiko portofolio sebesar 0,069750. Evaluasi kinerja portofolio optimal yang terbentuk diukur berdasarkan ukuran rasio Sharpe, Modigliani Square dan Treynor. Dari hasil penelitian didapat bahwa portofolio optimal yang dibentuk dengan Capital Asset Pricing Model (CAPM) layak untuk diinvestasikan.

Abstract

Portofolio optimal adalah portofolio yang menguntungkan dari segi return dan risiko bagi para investor. Pada penelitian ini digunakan metode Single Index Model untuk membentuk portofolio optimal. Setelah portofolio optimal terbentuk, dilakukan pengukuran kinerja portofolio dengan Rasio Sharpe, Rasio Treynor, dan Rasio Jensen. Serta menganalisis pengaruh dari Fama-French Three Factor Model yaitu yang terdiri dari Premi Risiko, Size, dan Book to Market Equity terhadap return saham. Objek penelitian ini adalah saham-saham yang konsisten berada pada Indeks PEFINDO25 pada periode Agustus 2019 - Januari 2021. Hasil penelitian menunjukkan terdapat 3 saham yang menjadi saham pembentuk portofolio optimal. Untuk hasil analisis pengaruh FamaFrench Three Factor Model menunjukkan bahwa Premi Risiko memiliki hubungan yang searah dan berpengaruh signifikan terhadap return saham, sedangkan Size dan Book to Market Equity memiliki hubungan yang searah namun tidak berpengaruh signifikan terhadap return saham. Kedua variabel tidak signifikan diduga karena pada periode data penelitian terjadi Covid-19.

Abstract

The aim of this research is to model the number of airplane passengers at Soelkarno-Hatta airport using a model hybrid SARIMA-FTSMC. The data used in this research is secondary data in the form of data on the number of airplane passengers at Soekarno-Hatta airport from January 2010 to May 2023 which was obtained via the websitebps.go.id. After analyzing the data, the best model was obtained in the SARIMA model, namely SARIMA(1,1,1)(0,1,1)12. Then based on the residual value from the processed data SARIMA will be modeled using the FTSMC model. Next, the residual value of SARIMA(1,1,1)(0,1,1)12 which has been modeled using the FTSMC model is added to the modeling value from SARIMA (1,1,1)(0,1,1)12 known as a modelhybrid SARIMA-FTSMC, with the aim of obtaining a higher level of accuracy or smaller error compared to the SARIMA model. After that, the accuracy level of the model is calculatedhybrid SARIMA-FTSMC uses MAD, MSE, and MAPE. In this research, the level of accuracy of the model was very good, this was shown by the MAPE value being less than 20%.

Abstract

Stunting is one of the national health problems in Indonesia, where children experience growth failure. This study aims to construct a model for the classification of height gain of stunting toddlers in West Sumatra Province using the Bayesian binary quantile regression method. Quantile analysis is used in the Bayesian concept to produce more effective and natural estimates, especially for data that are not normally distributed. In the Bayesian approach, the Asymmetric Laplace Distribution (ALD) is used in determining the likelihood function as the basis for forming the posterior distribution used in the parameter estimation process. Bayesian binary quantile regression is an extension of quantile regression where the scale of the dependent variable used is binary. The research data used is data on 1000 stunting toddlers in West Sumatra Province in August 2021 and February 2022. In this study, it was found that the Bayesian binary quantile regression method at quantile 0.50 was the best conjecture model in classifying the level of height gain of stunting toddlers in West Sumatra Province. The criteria for model goodness are based on the greatest accuracy value. Factors that are significant in influencing the height gain of stunting toddlers in West Sumatra Province are birth weight, exclusive breastfeeding, and immunization
