Abstract

Penelitian ini di lakukan untuk mengetahui respons pertumbuhan dan produksi tanaman kedelai (Glycine Max) terhadap pemberian alelopati lalang ( Imperata cylindrica ) dan babadotan (Ageratum Conyzoides yang di laksanakan di lahan Fakultas Pertanian Universitas Sumatera Utara yang di mulai pada bulan April sampai bulan juli 2017, menggunakan rancangan acak kelompok non faktorial, dengan perlakuan ekstrak alelopati lalang dengan 0, 50, 100, 150 ml dan ekstrak alelopati babadotan dosis 50, 100, 150 ml. Hasil penelitian menunjukan pemberian alelopati babadotan berpengaruh nyata terhadap parameter diameter batang, jumlah polong hampa, jumlah polong berisi, cabang produktif.

Abstract

One of causes coffee germination process takes a long period of time, because of the caffeine contained in coffee beans can inhibit the activity of amylase enzyme plays a role in the coffee germination process. Therefore, a study was conducted on the provision of Natural Growth Regulatory Substances (Natural PGR). This research was conducted at the Green House, Faculty of Agriculture, Univeritas Sumatera Utara, Medan from October 2019 to January 2020 using a Randomized Block Design (RBD) with two treatment factors : Factor 1 Natural PGR: A0 (water), A1 (bamboo shoot extract), A2 (shallot extract), and A3 (bamboo shoot extract + shallot extract). Factor 2 soaking duration : L1 (6 hours), L2 (12 hours), and L3 (18 hours). The results showed that the application of natural growth regulators (bamboo shoot extract or shallot extract) significantly increase the germination rate and seed vigor index. Soaking durationof 18 hours significantly increase presentation of germination but not different significantly from soaking for 12 hours, but there was no interaction between the two treatment factors.

Abstract

Soursop (Annona Muricata Linn.) is a plant that has hard seeds that inhibits germination. One way that can be done to accelerate the process of germination of soursop is by scarifying and using natural growth regulators. This research aim was to identify the effect of scarification and immersion of natural growth regulators on the viability of soursop seeds. This research was conducted at the USU Faculty of Agriculture from July to September 2018 by using a Completely Randomized Design of two treatment factors namely, (1) Scarification (without scarification / control and scarification) and (2) Immersion of Natural Growth Regulators (No Immersion / Control, Immersion with young coconut water; red onion extract and young coconut water). The scarification treatment and immersion of young coconut water and/or red onion extract gave the highest yield, significantly on plant height, leaf number and vigor index.

Abstract

This study explores the implementation of a holistic community service program in Siponjot Village, North Sumatra, aimed at enhancing non-formal education, economic sustainability, and environmental resilience. Through the "Marsiajar Manang Didia Pe" initiative, the program promotes a flexible learning system aligned with local cultural values, addressing gaps in formal education. Key components include training in agricultural practices focusing on coffee and mahogany cultivation alongside the introduction of data-driven decision making tools such as economic mathematical models and QR codes for improved information management. Results indicate improved community engagement, increased agricultural productivity, and enhanced digital literacy. The findings highlight the critical interplay between education, technology adoption, and sustainable practices in fostering community empowerment and resilience against environmental challenges.
