Abstract

Gelatin has been widely used as an additive in food industry pharmaceutical, and cosmetic. The similar physical appearance between bovine and porcine gelatin causes an issue for some communities like a Muslim due to awareness of halal food. This study aims to produce gelatin from femur bones of bovines with acid hydrolysis and their characteristics compared to standard gelatin of bovine and porcine. Bovine and porcine bones were soaked in 5% HCl for 10 days and every 2 days a HCl solution was replaced to get ossein. Ossein is hydrolyzed by gradual heating at 65, 75, and 85oC. Gelatin confirmed by the physico-chemical characters, FT-IR and analysis amino acid with HPLC.The results showed that the yield of bovine gelatin was 4.33%. The physico-chemical characters of bovine gelatin resulting from isolation and bovine gelatin standards are in conformity with porcine gelatin standards and meet the requirements of SNI 06-3735-1995 and GMIA. Therefore, bovine gelatin is specifically capable of substituting porcine gelatin for application in the pharmaceutical field. The FTIR spectrum of bovine gelatin shows the presence of amide A, amide I, amide II and amide III groups. The amino acid characters of gelatin were identified as glycine (13.57%) and proline (1.62%) for bovine gelatin and glycine (0.51%) and proline (0.09%) for porcine gelatin.

Abstract

Penelitian ini menguji pengaruh gaya kepemimpinan dan kompensasi terhadap kinerja karyawan dengan motivasi kerja sebagai variabel mediasi pada perusahaan manufaktur di Cikarang Selatan. Data dikumpulkan dari 101 karyawan tetap menggunakan kuesioner daring. Analisis Structural Equation Modeling (SEM-PLS) menunjukkan bahwa gaya kepemimpinan memiliki pengaruh signifikan terhadap kinerja karyawan (koefisien jalur = 0.276, p = 0.046) dan motivasi kerja (koefisien jalur = 0.709, p < 0.001). Kompensasi berpengaruh signifikan terhadap motivasi kerja (koefisien jalur = 0.262, p = 0.001), tetapi tidak memiliki pengaruh langsung terhadap kinerja karyawan (koefisien jalur = 0.009, p = 0.914). Motivasi kerja terbukti memiliki pengaruh signifikan terhadap kinerja karyawan (koefisien jalur = 0.667, p < 0.001). Hasil ini menegaskan pentingnya gaya kepemimpinan dan motivasi kerja dalam meningkatkan kinerja karyawan di sektor manufaktur.

Abstract

The purpose of this study is to analyze the implementation of quality management systems and their role in increasing consumer trust in local MSME products in Muara Teweh City. This study also aims to identify aspects of quality management that influence the development of consumer trust, as well as the obstacles faced by MSMEs in implementing them. This study uses a qualitative approach with a descriptive method. The research subjects consisted of local MSME business actors and consumers in Muara Teweh City selected through purposive sampling techniques. Data were collected through interviews, observations, and documentation. Data analysis was carried out through the stages of data reduction, data presentation, and conclusion drawing. The results of the study indicate that the implementation of quality management systems in MSMEs in Muara Teweh City is still simple and not yet fully standardized, especially in the aspects of SOPs, documentation, and quality control. Nevertheless, the application of quality management principles such as maintaining product consistency, process control, and complaint handling can increase consumer trust. Consumer trust is built through consistent product quality, product safety, and the responsibility of MSME business actors in meeting consumer expectations.
