The purpose of this studies to determine (1) the difference in the effect of the aplication job experience and the demonstration method toward student’s learning achievement for cognitive ability on BCMRCIS (2) the difference in the effect of high and low learning motivation toward student’s learning achievement for cognitive ability on BCMRCIS (3) the interaction in the effect of the learning method and student’s learning motivation toward learning achievement for cognitive ability on BCMRCIS. (4) the difference in the effect of the aplication job experience and demonstration method toward student’s learning achievement for psychomotor ability on BCMRCIS. (5) the difference in the effect of high and low learning motivation toward students’learning achievement for psychomotor ability on BCMRCIS (6) the interaction in the effect of the learning method and student’s learning motivation toward learning achievement for psychomotor ability on BCMRCIS.This research type is a scientific experiment. Data analysis used ANAVA 2 ways with fictorial design 2x2. The population is a class of XII Light Vehicle Engineering (LVE) Skills Competence SMK Muhammadiyah Kudus as many as 170 students.

(2) there is no difference in the effect  of high and low learning motivation toward student’s learning achievement for cognitive ability on BCMRCIS, the decision test   (H0 is accepted). (3) there is no the effect in the interaction between the learning methods and  student’s learning motivation toward learning achievement for cognitive ability on BCMRCIS, the decision test  (H0 is accepted). (4) there is a difference in the effect of the aplication job experience and demonstration method toward student’s learning achievement for psychomotor ability on BCMRCIS, the decision test   (H0 is rejected). (5) there is a difference in the effect of high and low learning motivation toward student’s learning achievement for psychomotor ability on BCMRCIS, the decision test   (H0 is rejected). (6) there is no the effect in the interaction between the learning method and  student’s learning motivation toward learning achievement for psychomotor ability on BCMRCIS, decision test   (H0 is accepted).Keywords: job experience, demonstrations, motivation, academic achievemen

Abstract

The aims of this study were to convert the starches from iles-iles tubers (Amorphophalus campanulatus) and sorghum grains (Sorghum bicolor L) into bioethanol as an alternative energy. Both of these agricultural products contains a high content starches and they do not use as the major foods in Indonesia. To find out the maximum ethanol concentration and yield, both the raw materials were converted to ethanol on various process variables including the concentration of flour substrate solution (100-300 g/L), β-amylase enzyme concentration (0.8 - 6.4 ml/kg of flour ), the  concentration of dry yeast S. cerevisiae (2-15 g), and fermentation time (72-168 hours). The results showed that at the flour substrate concentration of 250 g/L produced the maximum ethanol contents of 100.29 g/L and 95.11 g/L   for iles-iles and sorghum, respectively. Effect of β-amylase enzyme in the saccharification process showed that at concentration  of 3.2 ml/kg  the maximum reducing sugar content of 204.94 g/L and 193.15 g/L  for iles-iles and sorghum substrate, respectively were generated therefore it was corresponding to the maximum ethanol production. The concentration effect of dry yeast S. cerevisiae in the fermentation stage for the iles-iles and sorghum substrate revealed that the maximum ethanol obtained at 5 g yeast activated in 100 ml medium starter resulted the highest ethanol content 100.29 g/L 95.11 g/L for iles-iles and sorghum substrate, respectively. To determine the effect of fermentation time on ethanol yield from iles-iles and sorghum substrate, the fermentation process were performed at 3, 5, and 7 days. The maximum ethanol fermentation was obtained at 5 days fermentation. The ethanol yield is calculated by weight of ethanol is formed (g) divided by the weight of flour (g). Based on the experiment results, conducted, generally the highest ethanol yield of iles-iles was higher than that of sorghum flour. The highest yield (g/g) iles-iles and sorghum flour were 71.25 and 68.92 respectively

Abstract

The Information Technology and Data Base Unit (UTIPD) is one of the units at the XYZ State Islamic Religious College (PTKIN) which is tasked with managing and developing information system management, network and application maintenance, managing databases, and developing other information technology (IT). This research aims to evaluate governance and risk management at UTIPD at PTKIN XYZ. As a higher education institution that continues to develop, PTKIN XYZ relies heavily on information technology to support its operations, administration and academic activities. However, with the increasing complexity of information systems and associated risks, an in-depth evaluation of how IT governance and risk management is implemented is needed. The COBIT 2019 framework, which is an international standard framework for IT governance and management, is used in this research to assess IT governance and risk management capabilities at UTIPD. The primary focus of this evaluation is to determine the extent to which current IT governance practices meet expected standards, as well as to identify areas requiring improvement. This research includes an analysis of COBIT 2019 domains that are relevant to IT governance and risk management. The results of this research show that the APO07 domain and APO12 domain processes only obtained capability level 2 and obtained a gap value (GAP) of 1 each. In addition, this research also presents recommendations for improving IT governance and risk management at PTKIN XYZ, with the aim of Finally, to ensure that this university can utilize information technology optimally, reduce risks, and support the achievement of its strategic goals. It is hoped that the findings from this research can become a reference for PTKIN XYZ and other higher education institutions in strengthening IT governance and risk management.

Abstract

Unit Teknologi Informasi dan Pangkalan Data (UTIPD) adalah salah satu unit di Perguruan Tinggi Keagamaan Islam Negeri (PTKIN) XYZ yang bertugas mengelola dan mengembangkan manajemen sistem informasi, perawatan jaringan dan aplikasi, mengelola basis data, serta mengembangkan teknologi informasi lainnya. Dalam pelaksanaan tugasnya, UTIPD memerlukan adanya manajemen risiko. Manajemen risiko mempunyai peranan penting supaya UTIPD pada PTKIN XYZ mampu mengatasi dan juga meminimalisir ancaman yang ada di era digital saat ini. Penelitian ini menjelaskan penerapan Framework COBIT 2019 sebagai dasar untuk mengelola risiko yang mungkin timbul dalam operasional UTIPD pada PTKIN XYZ menggunakan 2 domain, yaitu EDM03 dan APO12. Selain itu, penelitian ini diharapakan mampu memberikan kerangka kerja komprehensif untuk mengidentifikasi, mengevaluasi, dan mengelola risiko terkait dengan ketersediaan layanan, integritas data, dan kepatuhan terhadap regulasi. Hasil penelitian ini menunjukkan proses domain EDM03 dan domain APO12 hanya memperoleh capability level 2 dan didapat nilai kesenjangan (GAP) masing-masing sebesar 1. Untuk dapat meningkatkan perolehan capability level, maka diusulkan rekomendasinya adalah menetapkan, memetakan, mengembangkan manajemen risiko dan mengadopsi teknologi informasi untuk mendukung manajemen risiko.
