Abstract

Agro-industrial waste in Indonesia is a significant problem for the environment. Optimization of agro-industrial waste utilization is an exciting thing to be researched further. This study aims to utilize agro-industrial waste to optimize laccase enzyme production. The agro-industrial waste used is in the form of bagasse, rice straw, and corn stalks. The waste is used as biomass and treated to extract cellulose through bio-delignification. Cellulose serves as a substrate substance in the production of laccase enzymes. Laccase enzymes can be applied as a biocatalyst in the environmental, pharmaceutical, and chemical industries. Cellulose from agroindustry waste was synthesized by heat treatment using steam explosion with the operation conditions 200°C and 10 bar for 10 minutes. The production of laccase enzymes was done using the green technology submerged fermentation method for 32 hours at 25°C. The optimal result in producing laccase enzyme is using substrate from corn stalks and adding nutrients with an activity value of 25.46 U/mL. The reaction kinetics of laccase enzyme and commercial enzyme against 0.1 M substrate were modelled using the Euler method, and the k value was 2x10-4 min-1 (crude laccase) and 1.9x10-2 min-1 (commercial laccase).

Abstract

Analisis Strategi Rekrutmen dan Penempatan yang Meningkatkan Kinerja Organisasi dalam Konteks Kajian Pustaka merupakan karya ilmiah yang berperan dalam merumuskan hipotesis untuk penelitian lanjutan yang akan menyelidiki dampak hubungan antara berbagai variabel. Artikel Literature Review ini dikembangkan melalui metode library research, dengan mengambil referensi dari sumber online seperti Google Scholar, Mendeley, dan platform online lainnya. Penelitian menunjukkan bahwa strategi rekrutmen yang cermat memungkinkan perusahaan untuk menarik talenta terbaik yang sesuai dengan tuntutan pekerjaan, sementara penempatan yang tepat memungkinkan karyawan untuk berkontribusi secara maksimal terhadap tujuan organisasi. Dengan demikian, hasilnya adalah sebagai berikut: 1) Rekrutmen berpengaruh terhadap kinerja organisasi, dan 2) Penempatan yang efektif juga berpengaruh terhadap kinerja organisasi. Dengan berfokus pada pencocokan karyawan dengan tugas dan tanggung jawab mereka, perusahaan dapat menciptakan lingkungan kerja yang produktif, memberikan kontribusi positif terhadap kinerja organisasi, dan bersaing secara efektif di pasar yang kompetitif.
