Abstract

Sudoku is a puzzle game that arranges numbers from one to nine on a board consisting of 9x9 squares. This game has a rule: the numbers arranged on a board cannot be the same in each row or column. The main goal of this Sudoku game is to complete the board and win by entering numbers into each empty box. Therefore, in this Sudoku game, there is only one valid solution. At the start of the game, several numbers are provided, which serve as clues for players to fill in the next box. The number of clues at the start of the game determines whether the Sudoku game level is difficult. The fewer the clues given, the more difficult it is to solve Sudoku. Solving Sudoku problems cannot be done manually, so several algorithms are needed, which require a lot of repetition and search functions. In this research, we will compare concepts in solving Sudoku using the Backtracking algorithm and the backtracking algorithm using the brute force technique. This comparison is seen from the effectiveness of solving Sudoku. The results of this research conclude that to solve Sudoku logic quickly and efficiently, the backtracking algorithm can be used compared to the Brute Force algorithm. This is because the backtracking algorithm has better complexity, and the solution steps are fast and “smart”. In contrast, the brute algorithm takes longer to complete because the brute force algorithm has to search for all the possibilities. The average time required to complete 10 9 x 9 puzzle tests with backtracking is 10910.96 ms, while the brute force algorithm takes longer, around 15871.90 ms.

Abstract

The main objective of this study was to assess the effect of communication quality and trust on behavior change, which supports the information system of health workers in public health centers through the mediating variable of readiness for change. Data were collected from 341 health workers working in public health centers in Indonesia through enumerators as data collectors. The statistical procedure is divided into descriptive analysis using SPSS 25 and structural equation model using bootstraps using Smart PLS 3.2.9. Structural Equation Model analysis found several results. The results positively affect the quality of communication, trust, willingness to change, and support for behavior change. In addition, the study readiness to mediate changes in communication quality and trust in supporting behavior change. Therefore, this study shows that the quality of communication and trust is significantly associated with behavioral changes that support the mediation readiness for change in health workers in East Java, Indonesia.The main question of this study is to assess the effect of communication quality and trust on behavioral change that supports the information system of health workers at public health centers through the variable of mediation readiness for change. Research has been conducted to answer this research question. It has been empirically proven that the quality of communication and trust affects changes in supportive behavior with and without mediation. We believe that the quality of communication and trust due to the combined effect of readiness for change produces behavioral changes that favor more than the quality of communication and trust itself.

Abstract

The rapid advancement of financial technology (fintech) has significantly reshaped how millennials in urban Indonesia manage their personal finances. Characterized by high digital literacy and mobile dependence, this generation has increasingly adopted fintech platforms for budgeting, saving, investing, and accessing financial protection. This study aims to analyze the role of fintech in supporting the personal financial planning of urban millennials, focusing on four key dimensions: cash flow management, savings, investment behavior, and financial protection. Using a qualitative approach with a literature review method, data were collected from ten peer-reviewed articles published between 2018 and 2025. The selected literature was analyzed thematically to identify patterns and synthesize insights. The findings reveal that fintech tools have facilitated more organized financial behaviors among millennials, enabling automation in savings, simplified investment access, and enhanced budgeting control. Moreover, fintech has played a vital role in democratizing access to insurance products. However, the study also found that the effectiveness of fintech is contingent upon the users’ level of financial literacy. While many millennials are eager to adopt digital financial solutions, gaps remain in risk awareness, long-term planning, and responsible consumption. Therefore, although fintech has the potential to transform financial planning, its benefits are maximized when accompanied by adequate financial education.

Abstract

Primary health care services serve as the frontline of public health development. Health cadres play a strategic role as intermediaries between communities and health facilities, yet their capacity remains limited. This community service project aimed to analyze the impact of strengthening cadres’ roles through structured training on knowledge, skills, attitudes, and self-efficacy in improving access to and quality of primary health care services in Jekek Village, Nganjuk Regency. The study applied a Participatory Action Research (PAR) approach involving 25 posyandu cadres. The evaluation showed a 25% increase in cadres’ knowledge based on pre- and post-test results. Community participation in posyandu increased by 20%, and cadres demonstrated improved skills in health data recording and communication with residents. Furthermore, the establishment of a communication forum between cadres, the puskesmas, and the village government contributed to the sustainability of the program. The findings highlight that effective empowerment strategies include continuous training, area-based mentoring, and non-financial incentives such as social recognition and competency certification. Empowerment through a participatory approach was proven to enhance access and quality of primary health care services and strengthen community-based health systems, although limited training opportunities and logistical constraints remain challenges. Sustainable policy support is therefore needed to further strengthen cadres’ capacity in primary health care delivery.
