Abstract

The Government of Indonesia is continuously striving to improve its education quality with the provision of scholarship programs, one of which is the Smart Indonesia Program (SIP). Students' interest in obtaining SIPs is increasing, but the selection process still relies on conventional methods. Without adequate IT support, the selection process for SIP scholarship candidates will be complex, less objective, and somewhat unfair. State Vocational High School (SVHS) 5 Surakarta was selected as a case study for this research to establish the selection process and the data collection methods used in previous years. The research aims to develop a Decision Support System (DSS) to assist in nominating students deemed eligible for SIP scholarship recommendations. The applied methods include Analytical Hierarchy Process (AHP) and Multi-Objective Optimization by Ratio Analysis (MOORA). Four criteria have been set in this DSS: card ownership status, total parental income, household income, and number of siblings. Each of which is further broken down into several sub-criteria and assigned a value for use in the AHP process. Upon comparing data from 2021 to 2023, it was found that the accuracy in 2021 was 92.9%, in 2022 it reached 94.7%, and in 2023 it recorded 92.3%. Based on the results of this system accuracy test, it can be concluded that the AHP and MOORA methods can be used to objectively produce recommendations for students eligible for SIP scholarships, based on the input criteria.

Abstract

Warung sate kambing Mbak Wid memiliki luas ruangan 3m x 5m dengan 1 kipas angin di dalam ruangannya. Kipas angin di warung sate kambing Mbak Wid cara pengoperasiannya masih manual dengan cara memutar potensiometer jika ada pembeli dan suhu di dalam ruangan tersebut panas, jika tidak ada pembeli kipas angin akan dimatikan. Pengoperasian kipas angin yang manual dapat merepotkan pegawai dan pemilik sate kambing Mbak Wid. Penelitian ini bertujuan untuk melakukan pengaturan kipas angin otomatis menggunakan sensor LM35 berbasis arduino di warung sate kambing Mbak Wid. Perancangan sistem dalam penelitian ini menggunakan metode waterfall. Metode pengumpulan data terdiri dari observasi, wawancara, literatur, eksperimen, dan dokumentasi. Pengaturan kipas angin otomatis menggunakan software Arduino IDE untuk memasukkan perintah dan Processing IDE digunakan untuk mengolah nilai suhu. Sensor LM35 mampu mendeteksi suhu ruangan dengan akurat pada jarak 1,5m - 2,5m. Pada jarak 3m sensor masih bisa mendeteksi suhu tetapi kurang akurat, sedangkan pada jarak 3,5 meter sensor akan mendeteksi suhu loncat tidak beraturan. Hasil dari penelitian ini pengaturan kipas angin otomatis dapat menyalakan dan mematikan kipas angin secara otomatis. Pengaturan kipas angin otomatis dapat menyalakan kipas angin secara otomatis pada suhu ≥ 270C dan dapat mematikan kipas angin secara otomatis pada suhu < 270C. Kipas angin dapat menyala dan mati secara otomatis pada pukul 09.00 - 10.00. Hal ini disebabkan karena pada pukul 09.00 - 10.00 terdapat suhu < 270C dan ≥ 270C. Pada pukul 11.00 - 16.00 kipas angin akan terus menyala, karena pada pukul 11.00 - 16.00 suhu selalu ≥ 270C. Mati dan menyala kipas angin belum stabil. Deteksi perubahan suhu dan waktu aktif berubah - ubah secara signifikan.

Abstract

The election process for the BEM president at Sahid Surakarta University previously used a website and log in using a username and password. The implementation of the election has several problems, such as multiple voting rights and an unregistered NIM. Therefore it is necessary to increase security by using applications and fingerprints for login. This study aims to build an application for the presidential BEM election system. The use of fingerprints to improve security in elections and avoid fraud during general elections. This research is software development using the waterfall method. The data collection is divided into three, namely observation, interviews, and documentation. In building the system, it uses the Embarcadero Delphi XE8. The database used by PostgreSQL and the fingerprint used by the Live 20R fingerprint. The system was tested using the Five View method. The fingerprint recording test used three different materials. The fingerprint recognition test used eight different finger conditions. The last test was the application delay time in the fingerprint response and the response to opening the menu. This research is the application of the presidential BEM election system for Sahid Surakarta University using fingerprint. The results of the tests carried out give 100% of the application running functionally. Meanwhile, fingerprint testing results show that the fingerprint machine only reads the fingerprints, while the fingerprint photos and the skin on the elbow cannot be read and stored by the machine. Fingerprint recognition testing using a fingerprint machine can read fingerprints in all conditions (wet fingers, oily fingers, inked fingers, pen crossed fingers, and sanitized fingers). However, fingerprints cannot read if the finger pattern is closed or blocked; namely, fingers closed one hand, fingers dusty, and fingers tied with thread. The time delay test produces an average time for fingerprint reading of 1.05 seconds, while the average time needed for menu opening is 0.25 seconds.

Abstract

House price predictions are an important thing in the property industry and are useful for buyers in making decisions. Principal Component Analysis (PCA) and Random Forest (RF) methods were used for accuracy analysis in predicting housing prices. Purpose of this research is to measure the accuracy of both methods also to compare RF method optimized with PCA and the one that has not been optimized. The data used is house prices in Karanganyar city based on data scraping results on the rumah123.com site. The analysis reveals that Jaten has the highest number of house sales, and sales of houses with land ownership certificates are also the highest. Of the 10 variables used, land area and buildings have the most influence on selling prices. The model training results show that the RF and PCA methods combination has more optimal value than only using the RF method. The error rate of the PCA method is smaller, averaging 0.0257, making its value more consistent than using only the RF method, which has a larger error value with an average of 0.0332. The model training time using PCA is faster (5005.75) than only using the RF method (6099.25)

Abstract

Purpose - This article examines the role of tax knowledge and tax awareness in improving tax compliance. The topic is important because compliance depends not only on taxpayers’ understanding of tax rules, but also on motivational and administrative factors. Design/methodology/approach - This study used a Systematic Literature Review guided by the PRISMA framework. Articles were collected from the Directory of Open Access Journals and limited to peer-reviewed studies published between 2022 and 2026. Selected studies were analyzed using qualitative descriptive synthesis. Findings/Results - The review shows that tax knowledge generally improves tax compliance by strengthening understanding of tax obligations and procedures, while tax awareness is a more consistent driver of compliant behavior. The findings also indicate that tax education, socialization, trust, fairness, service quality, and user-friendly digital systems reinforce compliance outcomes. Originality/Value - This study presents tax compliance as a behavioral and institutional outcome shaped by cognitive, attitudinal, and administrative factors. The main implication is that efforts to strengthen voluntary compliance should combine taxpayer education, awareness building, fair administration, and accessible digital services.

Abstract

Institutional growth in higher education relies heavily on understanding applicant demographics and behavioral patterns to optimize recruitment strategies. This study presents a hybrid data mining pipeline combining Self-Organizing Maps (SOM) and K-Means clustering to segment student applicant data. SOM is utilized to project high-dimensional demographic and admission attributes onto a lower-dimensional topological space, while K-Means partitions the mapped structures into distinct, actionable segments. The clustering quality is rigorously evaluated using the Davies–Bouldin Index (DBI), where a minimum non-negative DBI value indicates optimal inter-cluster separation and intra-cluster cohesion. Empirical results on applicant records reveal distinct target profiles based on geographic origin, prior educational background, chosen study programs, and information channels. These findings provide university management with descriptive intelligence to tailor targeted marketing campaigns and resource allocation, replacing non-targeted recruitment practices with data-driven strategic planning.
