Motivating workers through the use of rewards and punishments, the management control system places an emphasis on output. Any decent employee will follow the rules set out by their employer and will push for their coworkers to do the same. Finding out whether company rewards and punishments have an effect on employee performance in a State-Owned Enterprise is the main objective of this study. Quantitative studies employ non-probability purposive sampling and associative causality studies. With the aid of SmartPLS, descriptive statistics were applied to 100 questionnaires. All of the study's variables were found to have a positive and statistically significant effect. With a t-statistic value of 4.218, employees believe that the company's performance reviews can positively affect their pay, benefits, and advancement opportunities. The company's punisment motivate employees to perform well in order to avoid pay cuts and promotion delays (t-statistic value 4.861). When workers' expectations regarding company assessments and reward are satisfied, their performance improves (t-statistic value 3.900). Therefore, it is reasonable to assume that, with proper implementation of evaluation and sanctions, staff performance will improve. While punishments are the most powerful incentive for improving performance, this study's original finding is that positive reinforcement in the form of awards can inspire loyalty and good conduct.

Parenting is the maximum effort of parents given to children to become individuals with noble character. Parenting patterns or parenting in Islam, is a complete unity that comes from the attitude of parents towards young children in how to care for, educate, guide, and foster children optimally based on the Qur'an and the Sunnah of the Prophet. The role of parents as a foundation in the household greatly influences the growth and development of children's attitudes, because the beginning of a child's life is in the hands of parents, this is as the Prophet said "Every child is born in a state of fitrah, then both parents make him a Jew, a Christian, or a Magian" (HR. Bukhori). In addition, parents also have many advantages in educating children, such as being able to care for children all the time with love, and being able to pay attention to each of their developments. This is different from education in schools which only takes half a day and is structured.In Q.S An-Nisa: 9. Talk to them (children) gently, kindly, politely, and call them with pleasant nicknames, such as my son, my darling, etc. Meanwhile, in Q.S An-Nisa: 9 with the word falyattaqullah, which means "Be fearful of Allah" has the intention of being able to equip children with aqeedah. So based on the last verse in Q.S An-Nisa: 9 which reads wal yaquuluu qaulan sadiida, which means "and let them say the correct sentences". Based on the last paragraph, the responsibility of parents in educating children is to have good morals and say the right words.

This article examines the state of education in Indonesia in 2023, focusing on both the challenges and opportunities facing the system. Education in Indonesia has undergone significant transformation over the past decade, but several barriers remain, such as disparities in access, quality, and infrastructure between urban and rural areas. Despite these challenges, recent reforms and the increased use of technology have provided promising avenues for improvement. The study analyzes the national education policies, including the impact of the Merdeka Curriculum, and evaluates the role of digital learning platforms in addressing the educational needs of Indonesia’s vast population. Additionally, the article highlights key issues such as teacher training, student engagement, and education for sustainable development. By examining both the progress made and areas requiring further attention, this paper offers a comprehensive view of the Indonesian educational system in 2023. The findings suggest that while substantial improvements have been made, systemic inequities and the rapid pace of technological integration pose both challenges and opportunities for educators, policymakers, and students alike.

The purpose of this study was to determine the index of plankton diversity in the Aek Rao River, Gunung Tua. The research was carried out from April to May 2022 in the Aek Rao River, Gunung Tua. The sampling method used purposive random sampling which consisted of 3 observation stations, namely station 1 upstream, station 2 for residential areas and station 3 for densely populated areas. The results showed that the composition of plankton in the Aek Rao River, Gunung Tua consisted of 3 classes of phytoplankton, namely Bacillariophyceae, Chlorophyceae and Cyanophyceae, while the zooplankton class consisted of 4 classes, namely Mastigophora, Monogononta, Crustacea and Ciliophora. The highest diversity index in phytoplankton was obtained at station 1 of the sand mining area with a value of 1, 39 which indicates that the level of diversity is in the medium category. In zooplankton the highest diversity index was found at station 3 with a value of 0.33 which indicated that the level of diversity was included in the low category. While the highest dominance index for phytoplankton was found at station 3 in densely populated areas with a value of 0.43 while zooplankton was found at station 1 in a sand mining area with a value of 0.00563, both values ??indicated that there was no dominant plankton genus in that area.
