Abstract

The yield of tomato plants in dryland areas has been suboptimal due to environmental constraints such as poor soil health and high sunlight intensity. Appropriate agronomic modifications are necessary to improve crop yields while maintaining soil health. This study investigated the impact of various agronomic modification treatments on the growth and yield of tomato plants in dryland regions. The experiment was conducted in Gumantar Village, North Lombok Regency, during the dry season from June to August 2023. The agronomic modifications included a seaweed biochar treatment at a rate of 10 tons per hectare and 45% shading, with a control group that had no modifications. Three treatments were tested on two varieties of tomato plants: hybrid and local superior. The treatments were organized with four replications in a randomized complete block design with split plots, where agronomic modifications served as the main plots and the tomato varieties as the subplots. The results indicated that the interaction of agronomic modifications and plant varieties impacted the growth of tomato plants and various environmental factors. The hybrid variety under shading treatment exhibited the best growth. Additionally, this hybrid variety produced 59.6% more fruit than the local superior variety, yielding an average of 66 fruits and weighing 3.00 kg per plant. This study suggests that incorporating agronomic modifications, such as biochar treatment and selecting the appropriate variety, can enhance tomato yields in dryland areas.

Abstract

Tanaman kopi arabika (Coffea arabica L.) merupakan salah satu komoditas perkebunan yang mempunyai nilai ekonomi tinggi. Kabupaten Lombok Timur, khusunya di daerah Sembalun menjadi salah satu sentra utama penghasil kopi. Namun, produktivitas kopi di daerah Sembalun cenderung mengalami penurunan setiap tahunnya akibat adanya gangguan hama. Dalam ekosistem pertanian, kehadiran predator alami memiliki peran penting karena mampu menekan populasi hama. Penelitian ini bertujuan untuk mengetahui jenis-jenis predator alami serta keanekaragaman dan kelimpahan predator alami pada tanaman kopi arabika (Coffea arabica L.) di Sembalun. Penelitian menggunakan metode deskriptif dengan pengamatan langsung di lapangan dan proses identifikasi predator dilakukan di Laboratorium. Penelitian ini dilaksanakan pada bulan September-Oktober 2025 di perkebunan kopi milik rakyat di Desa Sembalun, dan identifikasi predator dilakukan di Laboratorium Proteksi Tanaman, Fakultas Pertanian, Universitas Mataram. Terdapat sebanyak 228 individu predator yang terdiri dari 7 ordo, 23 family dan 40 genus. Nilai rata-rata tingkat keanekaragaman sedang (H’ = 2,251). Individu predator ditemukan dengan nilai rata-rata distribusi yang relatif merata antar genus (E = 0,718) kategori sedang dan dominansi (D = 0,2025) kategori rendah. Predator yang paling melimpah berasal dari genus Synemosyna (15,38%) di lahan I, genus Anoplolepis (53,37%) dan genus Dolichoderus (18,40%) di lahan II.

Abstract

Based on data from the Ministry of Education and Culture through the kemendikbud.go.id/ATS website as of April 30, 2025, the number of out-of-school children (ATS) in West Nusa Tenggara Province reached 73,247 children from primary to secondary education levels. Central Lombok Regency occupies the second highest position with the number of ATS of 13,938 children, after East Lombok Regency. Especially in the age group of 13-15 years, there were 4,252 children, consisting of children who had never been to school, junior high school dropouts, and elementary school graduates who did not continue their education. This condition shows that there are still strong challenges in achieving the 13-Year Compulsory Learning Program as well as potentially hindering the human resource development agenda as stated in the 4th ASTA CITA of the President of the Republic of Indonesia. Central Lombok Regency has 66 Community Learning Activity Centers (PKBM) and 1 Learning Activity Studio (SKB) which strategically play a role as an equality education provider for ATS. However, optimizing the role of PKBM in supporting the 13-Year Compulsory Learning Program still faces various limitations, both in terms of governance, management capacity, and student outreach strategies. This community service activity aims to strengthen the implementation of the 13-Year Compulsory Learning Program through the empowerment of PKBM in Central Lombok Regency. The implementation method includes mapping the condition of PKBM, management assistance and equality education service programs, training to build the capacity of managers and tutors, and facilitation of PKBM synergy with local governments and related stakeholders.
