Perbandingan Load Balancing Router Mysql Dan HAProxy Menggunakan SysBench dan Cluster Innodb Pada Sistem Operasi Centos: Comparison Of Load Balancing Mysql Router And HAProxy Using SysBench In Innodb Cluster On Centos OS
Load balancing merupakan penyeimbang server dalam mendistribusikan beban kerja ke beberapa server dengan mempertimbangkan kapasitas masing-masing server. Ketika beberapa server digunakan, layanan yang ada dapat tetap berfungsi meskipun salah satu server mengalami kegagalan. Dua model load balancing yang akan digunakan adalah MySQL Router dan HAProxy. Penelitian ini bertujuan untuk membandingkan kinerja MySQL Router dan HAProxy dari segi waktu respons, throughput, dan distribusi beban server. Selain itu, penelitian ini juga menguji sinkronisasi data antar server database dengan menggunakan Sysbench sebagai alat pengujian. Sysbench merupakan utilitas benchmark yang dapat mengevaluasi kinerja sistem melalui berbagai parameter pengujian. Hasil penelitian menunjukkan bahwa MySQL Router memiliki kemampuan load balancing yang signifikan dalam mendistribusikan beban dan memastikan ketersediaan server dibandingkan dengan HAProxy. Pengujian dengan thread (beban) terkecil hingga terbesar pada load balancer MySQL Router menghasilkan rentang TPS (Transaction Per Second) 2900 hingga 2600; seiring bertambahnya thread (beban), TPS yang diperoleh semakin menurun, dengan rentang waktu respons 2 hingga 50 ms. Namun, HAProxy menunjukkan nilai TPS yang lebih kecil, berkisar antara sekitar 900 hingga 800 TPS, tetapi menghasilkan waktu respons yang relatif lama, berkisar antara 8 hingga 160 ms. Pengujian sinkronisasi database menunjukkan efisiensi kedua model dalam menangani perubahan data pada server yang berbeda. Penelitian ini memberikan kontribusi yang signifikan terhadap pengembangan infrastruktur TI yang lebih andal dan efisien dalam organisasi, khususnya dalam konteks penggunaan MySQL InnoDB Cluster dan HAProxy pada OS CentOS.

Abstract
Load balancing is a server balancer that distributes the workload among several servers, taking into account the capacity of each server. When multiple servers are used, existing services can continue to function even if one server fails. The two load balancing models to be used are MySQL Router and HAProxy. This study aims to compare the performance of MySQL Router and HAProxy in terms of response time, throughput, and server load distribution. Additionally, this study also tests data synchronization between database servers using Sysbench as a testing tool. Sysbench is a benchmark utility that can evaluate system performance through various test parameters. The results of the study show that MySQL Router has significant load balancing capabilities in distributing loads and ensuring server availability compared to HAProxy. Testing with the smallest to the largest threads on the MySQL Router load balancer resulted in a TPS range from 2900 to 2600; as the thread (load) increases, the TPS obtained decreases, with a response time range of 2 to 50 ms. However, HAProxy showed a smaller TPS value, ranging from around 900 to 800 TPS, but resulted in a relatively long response time, ranging from 8 to 160 ms. Database synchronization tests also reveal the efficiency of both models in handling data changes on different servers. This research makes a significant contribution to the development of more reliable and efficient IT infrastructure within organizations, particularly in the context of using MySQL InnoDB Cluster and HAProxy on CentOS OS.

Pengembangan Pembangkit Biogas dalam Kajian Sains Islam untuk Keberlanjutan Pelestarian Lingkungan
Biogas is a renewable energy derived from the degradation of organic materials, such as agricultural waste, livestock waste, and others. Several Qur\u27anic verses in Islam explicitly support the wise and effective utilization of natural resources; this includes the concept of sustainability and sustainable management of resources. “Eat [therefrom] and pasture your livestock. Indeed, in that are signs for those of intelligence.” is an example of biogas management\u27 relationship with the Qur\u27an (QS. Thaha: 54). Biogas made from livestock manure is an example of wise resource utilization and is in line with Islamic teachings about not wasting natural potential. Using biogas as a renewable energy source reflects the concept of sustainability (istidamiyyah), which is highly encouraged in Islam. The use of biogas reduces the use of fossil fuels, reuses organic waste that normally pollutes the environment, and reduces greenhouse gas emissions. Biogas generation is closely related to Islamic teachings on environmental conservation, effective resource management, and the role of humans as khalifah on earth. By utilizing renewable energy such as biogas, Muslims can apply the teachings of the Qur\u27an to protect the Earth, prevent damage, and maintain the balance of the ecosystem

Optimization of Broiler Chicken Harvest Scheduling using Integer Linear Programming: A Case Study
An optimized scheduling system is essential for poultry farming to balance fluctuating market prices with fluctuating feed prices. In poultry farms, input costs account for over 90% of total expenses, with 66% allocated to feed and 25% to day-old chick purchases. This article presents an optimization model for chicken harvesting, using broiler chicken farming as a case study. A broiler chicken farm in Central Java is currently operating below optimal profitability because of a lack of a systematic harvest scheduling strategy. The Integer Linear Programming model was developed to obtain an optimal harvest schedule to maximize income with respect to operational constraints. The optimization indicates that the proposed schedule increases farm profit by 12.41% per production cycle, leading to an estimated additional yearly revenue of IDR 40,062,029. Furthermore, the sensitivity analysis indicates that market price and feed cost are the most significant factors that influence profitability, with market price fluctuations impacting profit by up to 100.17% and feeding cost changes affecting profitability by 66.10%. Minimizing the price of 5% feed can lead to an increase of 66% in profit and vice versa. This paper presents a framework of structured decision-making for poultry farms to obtain the highest possible profit and minimize loss occurrence by utilizing an optimal harvesting schedule
