Abstract

IInsect pathologists' attention to the potential of entomopathogenic fungi (EPF) as inducers of plant resistance has increased in recent years. Several types of EPF that have received attention as biocontrol agents for insect pest populations include Beauveria bassiana, Metarhizium anisopliae and Trichoderma sp. because they are able to infect and kill insects directly, has a wide host range, and has been used to control various types of insect pests. Apart from being able to infect and kill insect pests, EPF can also live endophytically in plant tissue and increase plant resistance to pest attacks. The presence of EPF as endophytes is able to induce plant resistance by stimulating an increase phytohormones production. In this article, we reviewed the role of fungi as entomopathogens, the characteristics of entomopathogenic fungi, and their role as inducers of plant resistance. The review was carried out by collecting information  from original articles and related reports which reviewed the results of research on the role of entomopathogenic fungi as plant resistance inducers by including the keywords entomopathogenic endophytic fungi, resistance induction, characterization, systemic resistance and herbivorous insects. This systematic review concludes that EPF as an inducer of plant resistance is a very promising control alternative in the development of plant protection management against insect pests.

Abstract

Ketersediaan pakan berkualitas menjadi tantangan utama bagi peternak sapi di Dusun I Bukit Gantung, Desa Sumber Mulyo, terutama pada musim kemarau ketika hijauan terbatas dan harga pakan komersial meningkat. Ketergantungan pada rumput dan jerami tanpa pengolahan menyebabkan rendahnya nilai nutrisi serta pertumbuhan ternak yang tidak optimal. Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan memberikan edukasi dan pelatihan kepada peternak mengenai pembuatan pakan fermentasi sebagai solusi aplikatif, murah, dan berkelanjutan. Metode pelaksanaan mencakup sosialisasi konsep fermentasi, demonstrasi teknis, dan hands-on training mulai dari pemilihan bahan, pencacahan, pencampuran dengan EM4, pengaturan kadar air, hingga pengemasan anaerob dan proses inkubasi. Evaluasi dilakukan melalui pre-test dan post-test untuk mengukur peningkatan pengetahuan dan keterampilan peserta. Hasil kegiatan menunjukkan peningkatan signifikan antara 40% hingga 54% pada aspek pemahaman konsep dasar, teknik pengolahan, serta kemampuan menganalisis kesalahan fermentasi. Pelatihan ini terbukti efektif dalam membangun kapasitas peternak untuk memproduksi pakan fermentasi secara mandiri, memanfaatkan limbah pertanian, dan mengurangi ketergantungan pada pakan komersial. Penerapan teknologi fermentasi diharapkan mampu meningkatkan produktivitas ternak serta mendukung praktik peternakan yang lebih efisien dan berkelanjutan.

Abstract

This study aims to identify students' entrepreneurial intentions at universities in Medan City. This research was conducted due to the issue of unemployment caused by the skill competencies of agribusiness graduates, the generally low interest among students in creating job opportunities, and the declining enthusiasm for entrepreneurship in the agricultural sector. This study employed a survey method with a research population consisting of 920 agribusiness students from the Faculty of Agriculture in Medan City, spread across three universities: UMA, UMSU, and USU. The sample for this study consisted of 90 students from the three universities. The results show that students' entrepreneurial intentions, particularly at universities in Medan City, demonstrate a high level of interest; however, there is a need for accelerated learning and hands-on practice in entrepreneurship. Entrepreneurial intention in Indonesia, especially at universities in Medan City, falls into the high category. The higher the personal values and personalities aligned with entrepreneurship among students, the higher their level of entrepreneurial intention. This indicates that the students' entrepreneurial intentions reflect a positive response toward entrepreneurship.

Abstract

Lowland rice farming is the main source of income for farmers in rural Indonesia and plays a strategic role in national food security. However, structural challenges such as high production costs, fluctuations in grain prices, and limited access to modern agricultural technology still limit improvements in farmer welfare. This study aims to analyze the level of income and cost efficiency of lowland rice farming in Tanjung Morawa District, Deli Serdang Regency. Using a quantitative descriptive approach through a case study design, primary data were collected from 46 farmers selected purposively, supported by secondary data from related agencies. Analysis techniques include calculating fixed and variable costs, revenues, and net income, complemented by an analysis of the business efficiency ratio using the Revenue/Cost (R/C) indicator. The results of the study indicate that rice farming in this area provides significant economic benefits with adequate cost efficiency, although labor and production input components are dominant burdens. These findings emphasize the importance of optimizing the allocation of production inputs and utilizing efficient agricultural technology as a strategy to increase farmer income. The main contribution of this study is to provide a relevant empirical basis for regional agricultural policy making and encourage the adoption of a data-based approach in evaluating the economic feasibility of sustainable rice farming.
