Abstract

Chitin extraction from house crickets (Acheta domesticus) has been optimized by combining a green method using Deep Eutectic Solvent (DES) and sonication heating, thereby reducing environmental impact and improving time efficiency. The extraction process consisted of insect preparation, delipidation, demineralization, and deproteinization. The results show that the green process method with DES and sonication heating is effective in enhancing time efficiency, reducing mineral content by 56.52%, decreasing protein content by 84.94%, and increasing the degree of acetylation by 21%. However, there was a slight difference in the deproteinization results when compared to the cricket samples treated with reflux. FTIR analysis confirmed the purity and structural characteristics of the extracted chitin

Abstract

Political participation of young voters has a strategic role in local democracy. This research aims to analyze the factors inhibiting young voters' participation in the 2024 Bengkulu regional election using Chi-Square analysis. This descriptive-analytic quantitative research involved 124 respondents aged 17-29 in the 2024 Bengkulu regional election, analyzing four variables: political knowledge, psychological factors, social environment, and technical constraints. Using the Fisher Exact test, the results showed no significant relationship between the variables and the voting decision. Interestingly, the participation rate of young voters is quite high, indicating the complexity of the dynamics of political participation of the younger generation. The research findings provide a new perspective on the dynamics of young voters' political participation, providing a foundation for the development of strategies to increase young people's political engagement in future elections.

Abstract

Penelitian saat ini bertujuan untuk mengembangkan kitin yang ramah lingkungan dan ekonomis dengan berbagai macam aplikasi menggunakan asam organik untuk demineralisasi jangkrik rumah. Sampel kitin diekstraksi dari jangkrik rumah (Acheta domesticus) dan langkah demineralisasi dilakukan dengan tiga asam organik (sitrat, asetat, dan oksalat). Kitin yang diekstraksi dengan asam asetat pada proses demineralisasi menunjukkan hasil ekstraksi tertinggi dengan hasil sebesar 6% dibandingkan asam organik lainnya. Sedangkan pada proses deproteinasi menggunakan larutan DES (Deep Eutectic Solvent) sampel yang diesktraksi menggunakan asam oksalat berhasil mendapatkan %DP sebesar 97,7% yang artinya hampir seluruh kandungan protein pada sampel berkurang. Pita karakteristik dan gugus fungsi kitin diidentifikasi dengan spektrum FTIR yang menunjukan struktur kitin pada penelitian ini sama dengan kitin komersil. Pada penelitian ini, asam organik sama efektifnya dengan asam mineral untuk demineralisasi jangkrik rumah. Proses yang dikembangkan membuka kemungkinan untuk memproduksi kitin dengan cara yang lebih ramah lingkungan dan dengan biaya yang lebih rendah di banyak sektor industri.
