Abstract

Penelitian ini dilakukan dengan tujuan adalah untuk menentukan dosis mikoriza dan pupuk Grand K yang tepat dalam meningkatkan pertumbuhan dan hasil tanaman bawang merah pada lahan kering masam. Penelitian ini berlangsung di Unit Percobaan Terpadu (UPT) Fakultas Pertanian Universitas Islam Riau, Jalan Air Dingin Ujung, Pekanbaru, dari bulan September sampai November 2023. Studi ini menerapkan metode Rancangan Acak Lengkap (RAL) yang melibatkan dua faktor dan diulang sebanyak 3 kali. Faktor pertama adalah dosis mikoriza, 5 taraf perlakuan yaitu 0, 125, 250, 375 dan 500 g/plot. Faktor kedua dosis Pupuk Grand K terdiri dari 4 taraf perlakuan; 0, 10, 15 dan 20 g/plot. Parameter yang diamati meliputi tinggi tanaman, umur panen, jumlah umbi per rumpun, berat basah umbi per rumpun, berat kering per rumpun, dan  susut bobot umbi. Analisis Anova dilakukan pada data pengamatan dan diuji lanjut BNJ taraf 5%. Hasil riset menunjukkan bahwa perlakuan mikoriza 500 g/plot dan Grand K 20 g/plot mampu menghasilkan tinggi tanaman, jumlah umbi/tanaman, berat umbi basah dan kering per tanaman serta susut umbi terbaik pada tanaman bawang merah. Perlakuan tunggal mikoriza 500 g/plot dan perlakuan tunggal Grand K dosis 20 g/plot memberikan perkembangan dan hasil yang lebih baik pada tanaman bawang merah.

Abstract

This study aims to determine the effect of using Google Classroom on the ability to design learning media and teacher professionalism at SMPN 3 Mandau. The method used is a quantitative approach with a quasi-experimental research design. The population in this study were 20 teachers at SMPN 3 Mandau, sampling was carried out using the total sampling technique. Data were collected through observation sheets distributed to 20 teachers, consisting of 10 observation aspects for the variable of the ability to design learning media, and 15 observation aspects for the variable of teacher professionalism. The results showed that the use of Google Classroom had a significant positive effect on the ability to design learning media with a coefficient value of 0.000 0.05. In addition, the use of Google Classroom has also been shown to increase teacher professionalism with a coefficient value of 0.301 and a significance of 0.002 0.05. Based on these findings, it can be concluded that the use of Google Classroom can improve the ability to design learning media and teacher professionalism, so it is expected to be a reference in the development of technology-based learning in schools. This research contributes to the development of teacher competencies in the digital era and encourages policies that support the use of technology in learning.

Abstract

The control of manufacturing overhead costs is a critical challenge in determining accurate product costs. This systematic literature review analyzes 17 selected articles to examine the effectiveness of costing methods, the influence of firm characteristics, and the methodological profile of research in this field. The findings indicate that Activity-Based Costing (ABC) consistently outperforms traditional systems in providing accurate overhead cost allocation and relevant information for strategic decision-making. The success of implementing such systems heavily depends on firm contingency factors, with product mix complexity and availability of organizational resources emerging as key determinants. Methodologically, existing research is still dominated by qualitative approaches and case studies, highlighting the need for more inferential quantitative research to strengthen external validity and the generalizability of findings. The implications of this research emphasize the necessity of aligning costing systems with specific firm contexts and encourage the development of further studies with mixed-methods designs to address the complexities of overhead cost control in the modern manufacturing era.
