Abstract

Tanning industry waste is potential to pollute the environment because it is using a  harmful chemical materials. One of many effort to prohibit the environmental pollution is a bioremediation using bacteria because bacteria can grow and adapt to any subtrats that has a organic materials. The diversity of bacteria is important to know because the bacteria covers most large species diversity on earth and its role as bioremediation. The purpose of  this research is to determine the value of the diversity index and the types of indigenous gram bacteria in waste water Leather Tanning Industry Malang. Data has been analyzed results of measurements of pH, temperature, conductivity, the number of  bacteria colonies, bacterial community structure (diversity, evenness, richness and dominance) and the results of bacterial gram staining.Diversity of indigenous bacteria colonies that has been found are low and the value is 0,36; 1,30 and 0,015. Type of indigenous gram bacteria found are streptococci negative (11%), streptococci positive (34%), Streptobacilli negative (11%), streptobacilli positive (34%), coccus negative (5%) and coccus positive (5%).

Abstract

Transformasi digital dalam pendayagunaan informasi mendorong institusi pendidikan dan penelitian untuk menerapkan teknologi berbasis web, baik dalam pengelolaan perpustakaan. Penelitian ini diarahkan untuk rancang bangun sistem informasi perpustakaan digital berbasis web yang secara efektif mengelola data koleksi buku, hasil penelitian, layanan bimbingan, serta catatan perkembangan mahasiswa secara terintegrasi untuk Perpustakaan BRIDA Kota Medan. Metodologi yang diterapkan dalam penelitian ini meliputi studi literatur untuk memperoleh landasan teori dan referensi sistem serupa, observasi terhadap proses manual yang berjalan di perpustakaan, serta pendekatan prototyping dalam pengembangan sistem guna memungkinkan umpan balik langsung dari pengguna terhadap rancangan antarmuka dan fitur. Hasil dari penelitian ini berupa prototipe sistem informasi perpustakaan digital yang mendukung pengelolaan koleksi secara efisien, mempermudah akses informasi bagi pengguna, serta menyediakan fitur pencatatan perkembangan mahasiswa secara sistematis. Dengan adanya sistem ini, diharapkan perpustakaan dapat bertransformasi menjadi pusat informasi digital yang mendukung kebutuhan akademik dan penelitian secara optimal.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) in the culinary sector require fast, organized, and efficient services to improve customer satisfaction. Bakso Mas Anto Marelan is one of the MSMEs that still manages orders and queues manually, which often causes problems such as unorganized queues, order recording errors, and service delays. This study aims to design a website for order management and an automatic queue number system to improve service efficiency at Bakso Mas Anto Marelan. The research method includes needs analysis, system design, implementation, and application testing. The designed website allows operators to manage order data, monitor order status, and automatically generate queue numbers. The automatic queue number system helps arrange customer service order fairly and transparently. The results of this study indicate that the implementation of an order management website and an automatic queue number system can accelerate service processes, reduce recording errors, and improve queue management. Therefore, the designed website is expected to be an effective solution to enhance service efficiency in MSMEs, particularly at Bakso Mas Anto Marelan.
