Abstract

Karakteristik tomat dengan kulitnya yang lembut mudah rusak saat mendapat tekanan, dan gesekan karena kondisi jalan yang rusak pada saat pengangkutan atau faktor mekanis lainnya.. Sifatnya yang perishable berpengaruh terhadap mutu fisik tomat terutama persentase kerusakan, susut bobot, kadar air, dan perubahan warna. Tujuan penelitian adalah untuk mengetahui pengaruh lama transportasi terhadap mutu fisik tomat. Penelitian telah dilaksanakan di Laboratorium Teknologi Pasca Panen Fakultas Pertanian dan Peternakan UIN Sultan Syarif Kasim Riau. Penelitian dilaksanakan pada Bulan September-Oktober 2020. Metode penelitian adalah eksperimen dengan Rancangan Acak Lengkap dengan tiga perlakuan (P1=0 jam transportasi (kontrol), P2=4 jam transportasi, P3=8 jam transportasi) dengan enam ulangan. Parameter pengamatan yaitu persentase kerusakan, susut bobot, kadar air (basis basah) dan warna. Data analisis  sidik ragam yang berpengaruh nyata  dilanjutkan dengan Uji Jarak Duncan. Hasil penelitian lama transportasi menunjukkan pengaruh yang sangat nyata terhadap persentase kerusakan, susut bobot dan kadar air, dan  lama transportasi tidak berpengaruh nyata terhadap perubahan warna. Kesimpulan, lama 4 jam transportasi dan 8 jam transportasi berpengaruh terhadap sifat fisik, meliputi persentase kerusakan, susut bobot, dan kadar air. Tetapi tidak berpengaruh terhadap perubahan warna tomat.

Abstract

This research comprised two variables, communication ability of Islamic education subject teacher as X (independent) variable and student learning activeness as Y(dependent) variable. This research aimed at knowing whether there was a significantinfluence of communication ability of Islamic education subject toward student learning activeness at State Junior High School 1 Tanah Putih Tanjun Melawan, Rokan Hilir Regency. This research was a Correlation. The subjects of this research were all students. The teacher 2 of population all of the eighth-grade students class VII and VIII (243 students) and an Islamic education subject teacher were the population of this research, The sample is 1 teacher and 54 students. Proportionate stratified random sampling technique was used in this research. Questionnaire, observation, and documentation were used to collect the data. The technique of analyzing the data was Product moment correlation. SPSS 16.0 for Windows program was used to analyze the data. Based on the data analysis, there was a significantinfluence that the index obtained was 0.455 and rtable was 0.2681 at 5% significant level and 0.3477 at 1% significant level. It meant that robserved was higher than rtable, it could be described as 0.2681<0.455>0.3477. Thus, H0 was rejected and Ha was accepted. It meant that there was a significantinfluence of communication ability of Islamic education subject teacher toward student learning activeness at State Junior High School 1 Tanah PutihTanjungMelawan, RokanHilir Regency.

Abstract

This study investigates lecturers’ pedagogical responses to student challenges in processing information for oral presentation skills in the era of artificial intelligence. Employing a qualitative case study design with thematic analysis, the study involved eight lecturers and 62 students from three private universities in Cimahi, Indonesia. Data were collected through in-depth interviews and Focus Group Discussions (FGDs) and analysed using Braun and Clarke’s six-phase thematic framework. The findings reveal that 1) all lecturer participants (100%) reported an erosion of students’ oral communication skills, manifested in a gap between high-quality visual artifacts and weak verbal performance, deficits in spontaneous responses, and degradation of non-verbal communication, indicating the role of artificial intelligence as a cognitive crutch, 2) lecturers responded to these challenges by diversifying pedagogical strategies, particularly through explicit AI usage policies (100%), intensified oral validation via spontaneous question-and-answer sessions (87.5%), and process-oriented assessment (75%), and 3) student responses were ambivalent, with the majority (77.4%) perceiving the new assessment approaches as fairer and more transparent, while a minority (22.6%) expressed resistance related to performance anxiety. These findings suggest that the most effective response to AI-related challenges is not the prohibition of technology, but a pedagogical redesign that prioritizes process validation, human interaction, and assessment security to maintain rigorous academic standards in Indonesian higher education.

Abstract

Brownish yellow is one of the characteristics of bore well water which indicates a high concentration of iron (Fe) that will affect human health and damage the aesthetic value. This study aims to purify the bore well water by reducing the concentration of Fe metal by adsorption of chicken bone activated carbon (CBAC) and implementing the results of research on the material of colloidal adsorption properties at Pekanbaru Telkom Vocational High School. CBAC is made through 3 steps namely dehydration at 50oC, carbonization at 400oC and activation with HCl, formic acid and NaOH pa. Each 1 gram of CBAC is mixed with the volume varied by 5; 10; 15; 20 and 25 ml. Measurements of Fe metal concentrations were carried out using Atomic Absorption Spectrophotometer (AAS) and the data obtained were then analyzed descriptively through tables and graphs. Maximum adsorption of CBAC was obtained in 20 ml of bore well water with a percentage reduction 99.92%. All results of treatment meet Fe metal quality standards as stipulated in Republic of Indonesia Minister of Health Regulation No. 416 of 1990. Analysis of student response questionnaires based on questionnaire analysis techniques obtained a cumulative value of 88.62% (very good).
