Abstract

Previously, we had constructed proline accumulating Pichia kudriavzevii yeast mutant (T-T2) that exhibited high temperature tolerance phenotype. In this study we then analyzed the ethanol production of the particular mutant isolate in various carbon (C) and nitrogen sources (N). Fermentation rate of T-T2 either in 4% glucose or substrate mixture (SM = 2%glucose : 2% xylose) was higher than WT strain. The highest CO2 evolving rate by T-T2 in glucose and SM was 57.0 ml/hour and 51.4 ml/hour, respectively, suggesting that T-T2 was capable of using xylose as C-source. T-T2 resulted significant increase of total evolved CO2 than WT strain in glucose as substrate. T-T2 isolate was capable of producing higher ethanol than its WT strains in various C-sources, including glucose, maltose, sucrose, xylose and SM. However, glucose was found as the most preferable C-source to produce ethanol (3.2%) whereas maltose was the least preferable one. T-T2 was found capable in using inorganic sources (NaNO3) to produce ethanol (2.4%) as compared to other N-sources (urea, (NH4)2SO4, NH4Cl). Ethanol production by T-T2 strain in NaNO3 was 16% higher than its WT strain. This data indicate, that NaNO3 is potentially applied as N source alternative to produce ethanol. Based on our study, mutant strain T-T2 shows higher fermentation rate than its WT strain in various sugar and N-sources. The fact that T-T2 could produce ethanol from SM in a similar fermentation rate to single glucose as substrate, suggesting its potential application in the 2nd generation of bioethanol productions.

Abstract

There has been delinquency among some students at SMP Negeri 2 Sompak. Examples of student delinquency that often occur are skipping school during class hours, smoking during class hours or outside class hours, and not having responsibility for doing school work or homework given by the teacher. Therefore, Christian religious education teachers are needed to educate, teach and guide students so that acts of delinquency do not occur again. The aim of the research is to explain the importance of PAK teachers in overcoming the delinquency of Christian students at SMP Negeri 2 Sompak so that students become role models for their family, church and the Indonesian nation they love. The author uses qualitative research methods using observation, interviews, documentation and literature techniques. The results found were that if PAK teachers were more committed and responsible in dealing with the delinquency of Christian students, then Christian students would increasingly experience changes in their lives from acts of delinquency. Conclusion: Religious Education teachers who serve at SMP Negeri 2 Sompak must be committed and responsible in overcoming the delinquency of Christian students at SMP Negeri 2 Sompak so that students are able to show commendable attitudes in family, church, national and state life now and forever.

Abstract

Model pembelajaran merupakan suatu studi pendekatan yang dipilih bagi pembelajaran orang dewasa, baik lewat pendidikan formal maupun informal. Alasan orang dewasa mengikuti pembelajaran karena orang dewasa memiliki animo yang tinggi untuk mengetahui sesuatu pengetahuan yang belum diketahui, meningkatkan kompetensi, kualifikasi, dan menerima motivasi eksternal untuk memperbaiki dirinya agar ke depan semakin melakukan perubahan peningkatan kinerjasitas. Tujuan orang dewasa mengikuti proses pembelajaran ialah untuk meningkatkan perilaku, pengetahuan, keterampilan, dan pemahaman; serta mengembangkan pengalaman hidup menuju ke arah kehidupan yang semakin baik. Metode penelitian kualitatif dengan pendekatan kepustakaan menjadi pilihan dalam penulisan artikel ini. Hasil penelitian ialah orang dewasa harus terus-menerus belajar dengan menggunakan berbagai model pembelajaran yang tepat untuk meningkatkan kompetensi, kualifikasi, dan mendapatkan pengalaman hidup dari pendidik dan sumber-sumber belajar supaya bersaing secara sehat di era masyarakat 5.0.
