Implementing regular preventive maintenance on the machines used in production activities is a key approach to achieve this goal. By performing scheduled maintenance on a regular basis, the strength of the machines can be maintained, ensuring their stability, and facilitating smooth production processes. Notably, the press machine serves as the primary printing equipment for the company's product manufacturing. Any breakdown in this machine can significantly disrupt production and lead to losses for the company. Frequent production interruptions due to sudden inspections and repairs are among the challenges faced by the company. To address this issue, it is recommended for the company to establish a specific preventive maintenance schedule for the press machine to ensure its stability. The Age Replacement method can be employed in creating this preventive maintenance schedule, as it determines the optimal replacement interval based on the component's age. By utilizing the Age Replacement method, the company can generate the most effective proposed scheduling required for maintaining the press machine in optimal condition.

The impacts of air pollution include respiratory, vision and heart problems and even the risk of cancer. The air quality monitoring system in existing conditions still requires improvements in system development, such as integration with the Internet of Things. This research aims to design and build an air quality monitoring system with parameters that monitor CO levels, dust particulate levels, temperature and humidity integrated with the Blynk platform which can be accessed in real-time, in an effort to support the SDGs program as a mandate of the world community through the PBB. The research method used is Analysis, Design, Development, Implementation, and Evaluation (ADDIE). The result of this research is to design an air monitoring system with specifications for detecting CO levels (200 ppm to 10,000 ppm), dust particles (sensitivity 0.1 mg/m 3), temperature (-40 o C to 80 o C), and humidity (0%-100%). Apart from that, in the long term the designed air monitoring system can be expanded, for example each industry has sensors installed in the chimneys and exhausts to detect whether the industrial exhaust is still within the permissible limits, as well as ground vehicle activity. It can also support SDGs programs including healthy and prosperous lives (point 3), clean and affordable energy (point 7), sustainable cities and settlements (point 11) and tackling climate change (point 13).

In selecting suppliers, most companies only focus on the sole consideration of price and raw material availability. This approach makes the supplier selection suboptimal, resulting in nonconformance to order specifications and delivery delays. This study conducted a supplier performance evaluation to provide an assessment of suppliers, enabling the company to identify the strengths and weaknesses of each supplier using the Vendor Performance Indicator (VPI) framework Quality, Cost, Delivery, Flexibility, and Responsiveness, which consists of a total of 13 sub-criteria and employs the Analytical Hierarchy Process (AHP). Based on results, the weighted values for suppliers I, K, L, M, and J were 0.285, 0.275, 0.185, 0.142, and 0.112, respectively. Based on the result, it is recommended that the company adopts a periodic to effectively monitor supplier performance, for better supplier selection and enhanced operational efficiency.

This research was attempted to model the factors of consumer buying behaviour in selecting Internet Service providers in Indonesia. Several attributes, namely service quality, price, customer perceived value, customer satisfaction, and brand image, were examined for their influence on consumer buying behaviour. Employing the purposive sampling method, this study selected 180 respondents that were surveyed using online questionnaires. The data were processed using the Structural Equation Modeling (SEM) with LISREL 8.8 software. The results showed that the attributes that had a significant positive effect on customer buying behaviour were customer perceived value, customer satisfaction, and brand image. Meanwhile, service quality and price did not have a significant effect on customer buying behaviour. However, these two attributes have a positive effect on customer perceived value. Other findings in this study are customer perceived value and brand image positively affect customer satisfaction. This result might be useful for the internet service provider as the consideration in developing a marketing strategy.

Until 2017, Indonesia is one of the countries with the highest internet users globally, with around 112,6 million internet users. On the other hand, many small businesses have not used the internet to advertise their products. This project's main objective is to design and develop a company profile website of CV Rian as one of the brick micro-industry in Nagrek, West Java, enabling people to search and access information easily and quickly. This project uses Waterfall Model as Sofware Development Life Cycle (SDLC), MySQL as the database, and PHP for server-side scripting. The database is used for storing posts, admin data, and images.

Proses pengelolaan keuangan industri kecil batu bata di kawasan Nagreg masih banyak yang bersifat konvensional/manual dan belum menggunakan perangkat lunak sistem keuangan untuk membantu proses pencatatan keuangan dalam bisnis batu bata. Selain itu, kegiatan pemasaran belum menggunakan media online sehingga konsumen masih terbatas. Aplikasi penyusunan laporan keuangan sederhana diharapkan bisa digunakan sebagai alat pengambil keputusan. Selain itu pembuatan website perusahaan dikembangkan untuk membantu perusahaan dalam bidang pemasaran. Hasil yang dicapai adalah aplikasi keuangan sederhana dan website bagi pengrajin batu bata. Penggunaan aplikasi keuangan dan website bisa dimanfaatkan untuk menentukan strategi pemasaran berbasis teknologi untuk meningkatkan daya saing.

Data menunjukkan bahwa obat yang telah tersertifikasi BPOM baru 13,41% yang sudah tersertifikasi halal. Sedangkan target pemerintah Indonesia mulai tahun 2019 produk gunaan halal yang beredar di Indonesia wajib bersertifikat halal, oleh karena itu dibutuhkan sebuah standar yang terdiri dari Sistem Jaminan Halal dan Cara Pembuatan Obat yang Baik. Penelitian ini menyusun sebuah standar yang mengintegrasika Sistem Jaminan Halal (SJH) dan Cara Pembuatan Obat yang Baik (CPOB) untuk membantu industri farmasi dalam mengimplementasikan kedua sistem tersebut, mengurangi redundansi dokumen dan mengefisienkan interaksi semua departemen terkait. Mengacu pada struktur ISO (International Organization of Standardization) bahwa struktur pembentukan sebuah standar adalah PDCA (Plan, Do, Check dan Act), mak...
