Abstract

Penelitian ini bertujuan untuk menentukan konsentrasi efektif ekstrak daun jambu biji (Psidium guajava Linn.) terhadap penyembuhan luka bakar pada mencit (Mus musculus). Ekstrak daun jambu biji diperoleh dengan cara maserasi menggunakan etanol p.a sebagai pelarut. Uji efektivitas ekstrak daun jambu biji terhadap luka bakar dilakukan terhadap mencit betina, yang telah dilukai pada bagian punggungnya dengan penginduksi panas berupa lempengan logam berukuran 2 x 2 cm dengan suhu 80oC selama 5 detik. Sampel uji dibagi menjadi enam kelompok perlakuan, yaitu kontrol negatif TPO (Tanpa Pemberian Obat), kontrol positif PEP (Pemberian Ekstrak Plasenta) dengan obat komersil (Bioplacenton) dan empat kelompok dengan ekstrak daun jambu biji dengan konsentrasi 1%, 3%, 5% dan 7%. Hasil penelitian menunjukkan bahwa pemberian ekstrak daun jambu biji berhasil dalam penyembuhan luka bakar pada mencit. Hasil analisis statistik menunjukan bahwa konsentrasi efektif ekstrak daun jambu biji adalah 1%, karena merupakan konsentrasi paling kecil yang memiliki nilai berbeda nyata dengan TPO namun tidak menunjukan perbedaaan nilai yang nyata dengan PEP dan ekstrak daun jambu biji konsentrasi lain.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan model pembelajaran Siklus Belajar (learning cycle) terhadap penguasaan konsep fisika. Metode penelitian yang digunakan adalah eksperimen semu (quasi experiment) dengan teknik non-equivalent control group design. Sampel diambil sebanyak 160 orang siswa Kelas XII yang terbagi dalam dua kelompok, yaitu kelompok kontrol yang belajar dengan model pembelajaran konvensional dan kelompok eksperimen yang belajar dengan model pembelajaran Siklus Belajar (learning cycle). Pengumpulan data dilaksanakan dengan observasi, dan tes akhir (posttest) untuk mengukur penguasaan konsep. Analisis data dengan metode Analysis of Varians (ANOVA) satu arah. Uji statistik menggunakan uji normalitas 1-Sample Kolmogorov-Smirnov, uji homogenitas dengan uji F (Fisher). Penelitian ini dilaksanakan mulai 24 Agustus 2015 sampai dengan 27 Oktober 2015.Hasil penelitian menunjukkan terdapat pengaruh penggunaan model pembelajaran terhadap penguasaan konsep fisika secara signifikan, ditunjukkan dengan nilai Fhitung = 6,369 > Ftabel = 4,10 dan sig. = 0,013 < 0,05.

Abstract

This study was aimed at: 1) producing an appropriate learning multimedia for agrarian laws in terms of the material and presentation aspects student responses, and 2) investigate the effectiveness of the developed multimedia to develop student learning outcomes. This was a research and development study. The results of the study were as follows. 1) Regarding the developed learning multimedia product: a) it had good quality in terms of the material aspect with a mean score of 4.10; b) it had good quality in terms of the presentation aspect with a mean score of 4.07; and c) the students' responses to the media attractiveness showed that the multimedia was attractive with a mean score of 3.82. 2) The effectiveness of the use of the developed learning multimedia to improve learning outcomes was indicated by the fact that: a) there was a score improvement (30.16%) from a mean score of 51.50 in the pre-test to 73.75 in the post-test; and b) there was an improvement in mastery by 60% among 20 students, from five students (25%) attaining mastery in the pretest to 17 students (85%) attaining mastery in the posttest. Therefore, the multimedia for Agrarian Laws learning is appropriate to apply.

Abstract

This study examines the effect of competence and work discipline on employee performance with job satisfaction as an intervening variable at the Department of Transportation, Agam Regency, West Sumatra. The research employed a quantitative design with a census sampling method, involving all 70 employees as respondents. Data were collected using structured questionnaires and analyzed using SmartPLS 4.0 with the SEM–PLS approach. Results revealed that both competence and work discipline have significant positive effects on employee performance, with discipline emerging as the strongest direct predictor. Competence and discipline also positively influenced job satisfaction, which in turn significantly enhanced performance. Mediation analysis confirmed that job satisfaction partially mediated the relationship between competence and performance, as well as between discipline and performance, with stronger effects observed for discipline. These findings highlight that employee performance improvement requires not only technical competence and behavioral discipline but also psychological satisfaction at work. The study contributes theoretically by extending human resource management literature in the public sector and practically by offering actionable insights for policymakers to strengthen discipline systems, align competencies with job roles, and enhance satisfaction through recognition and career development.

Abstract

This study aims to analyze the influence of terminal location and accessibility on safety/security through service reliability among logistics companies operating at Tanah Merdeka Terminal, North Jakarta. A quantitative approach was employed using a survey method. The study population consisted of approximately 40 logistics companies in the research area, all of which were included in the sample using saturated sampling technique. Data collection was conducted through questionnaire distribution between March and June 2025. Data analysis was carried out using Structural Equation Modeling based on Partial Least Squares (PLS-SEM) with the assistance of SmartPLS version 4.1 software. The results indicate that service reliability has a significant influence on safety/security. Additionally, terminal location indirectly affects safety/security through service reliability. However, accessibility was found to have no significant direct or indirect effect on service reliability and safety/security. These findings highlight the critical role of enhancing service reliability as a key factor in improving logistics safety and security.
