Abstract

Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae) or Coffee Berry Borer (CBB) is the most destructive major pest that causes quantitative and qualitative losses in Arabica coffee. The research aimed to calculate population, attack H. hampei, coffee yield losses, the measure distribution pattern of H. hampei on various Gayo arabica coffee varieties, and the analyze estimated decrease in the production of coffee based on population and attack H. hampei in Gayo arabica coffee. The location chosen as a place of observation and sampling is a smallholder coffee plantation with variations in elevation. Each area is determined by two points of observation and sampling locations. At each sampling location, 80 ripe or red coffees were taken, 80 dark or yellow coffees, and 80 young or green coffees (24 pieces per four branches per tree). The results showed that the population and attack of CBB pests on Gayo 3 varieties are relatively high compared to Gayo 1 and Gayo 2 varieties. The distribution pattern of CBB on all varieties of Gayo Arabica coffee showed an aggregated distribution based on population and attack. The decrease in arabica coffee production has the potential to occur on a variety Gayo 3.

Abstract

Coffee beans take a longer time to germinate and need a method to solve it. Plant Growth Promoting Rhizobacteria (PGPR) found in plant roots can produce phytohormones that can break the dormancy of the seeds and stimulate the growth of Arabica coffee beans. This study aims to study on the effect of PGPR from the roots of yellow and green bamboo to the growth of arabica coffee seeds. The experiment used a randomized block design with the first factor being the type of bamboo roots, namely yellow bamboo and green bamboo. The second factor was the concentration of PGPR which consisted of 4 (four) levels of PGPR concentration in water that are control (no treatment, 10, 20, and 30 ml.L-1 water).The results showed that the application of PGPR from bamboo roots had a significant effect on plant height, the number of leaves, fresh weight of crown plants, leaf fresh weight, shoot dry weight, and leaf dry weight of arabica coffee seeds. The application of PGPR from yellow bamboo roots with a concentration of 30 ml.L-1 gave a significantly effect on the growth of arabica coffee seeds. PGPR with a concentration of 30 ml.L-1 is suitable due to accelerating the growth of Arabica coffee seeds so that it becomes a solution in Arabica coffee seeds development.

Abstract

Terigas orange is a nationally superior variety from Sambas, West Kalimantan, but its fruit quality remains less competitive than imported varieties, which are typically brightly colored and seedless. Genetic improvement through gamma-ray irradiation was applied to enhance its traits. This study aimed to evaluate the effects of 6 kRad gamma-ray irradiation on the morphological and fruit characteristics of Terigas orange mutants. Conducted from May to July 2023 at the Screenhouse, Faculty of Agriculture, Jenderal Soedirman University. The experiment used a Randomized Block Design. The data were analyzed using Least Significant Difference and the Least Significant Increase. A test at the 5% level is used to compare the diversity of mutants with normals. Results showed significant variations in plant height, stem diameter, leaf width, and petiole length. Qualitative changes were observed in leaf shape, margin, base, type, color (upper and lower surfaces), and length. Mutant fruits exhibited stronger aroma, higher brix levels, a sweeter yet slightly sour taste, and more seeds compared to the normal.

Abstract

The decrease in corn crop yields in Riau Province was possibly caused by several factors, one of which was the infestation of plant pests such as the corn cob borer (Helicoverpa armigera Hubner). The primary choice for farmers to control H. armigera was using synthetic insecticides, but this could lead to various negative impacts. A solution to reduce the use of synthetic insecticides was the utilization of botanical insecticides, such as those derived from the leaves of chaya (Cnidoscolus aconitifolius I. M. Johnst). This research was conducted with the aim of determining the effective concentration of chaya leaf organic extract against corn cob borer larvae mortality in laboratory conditions. The experiment was conducted in a completely randomized design (CRD) with 5 treatments, each replicated 4 times, totaling 20 experimental units. Each experimental unit consisted of 10 third-instar H. armigera larvae. The concentrations of chaya leaf organic extract used were 0%, 0.25%, 0.50%, 0.75%, and 1%. Parameters observed included initial mortality time, lethal time 50 (LT50), lethal concentration 50 and 95 (LC50 and LC95), daily mortality rate and total mortality. The results indicated that the concentration of 0.75% of chaya leaf organic extract was effective in controlling H. armigera larvae. It caused a total mortality of 82.50%, with an initial mortality time of 6.25 hours and a lethal time 50 (LT50) of 29.75 hours after application.

Abstract

Oil palm (Elaeis guineensis Jacq.) cultivation is a primary economic sector in Indonesia, with North Sumatra being a leading production region. However, the sector's expansion, exemplified in the Bilah Sub-watershed, Labuhanbatu, has raised concerns regarding the deterioration of soil physical properties, posing a risk to long-term agricultural sustainability. While plantation age and topographic slope are identified as key influencing factors, their interactive effects remain inadequately examined. This study, therefore, aimed to analyze the differences in soil physical characteristics across varying oil palm ages and slope gradients. Conducted from May to August 2025 in Negeri Lama Village, the research employed a factorial design with three plantation ages (newly planted, 5, and 12 years) and three slope classes (0-3, 3-8, and 8-15%). Parameters assessed included soil texture, organic matter content, porosity, water content, and permeability. The results demonstrate that increasing plantation age positively correlates with improved soil conditions, marked by higher organic matter, porosity, water content, and permeability, alongside reduced bulk density. Conversely, steeper slopes significantly degrade these same properties. The study underscores the critical interaction between these two factors. Its importance for the oil palm industry lies in providing empirical evidence for developing site-specific soil management strategies. The findings advocate for enhanced conservation practices, particularly on slopes exceeding 8%, to mitigate degradation and ensure the ecological and economic sustainability of this vital commodity system.

Abstract

Indonesia's agricultural problems in rice cultivation are increasingly complex, threatening national food security. The attack of Xanthomonas oryzae pv. oryzae (Xoo) can cause decreased production of bacteria, resulting in rice disease bacterial leaf blight (BLB). The biological agent Bacillus subtilis (B. Subtilis) has the potential to control BLB disease. The study aimed to determine the effect of B. subtilis bacteria in reducing the intensity of Xoo attacks by comparing the use of pesticides. Xoo attacks by comparing the use of citronella vegetable pesticide and its effect on rice production. This experiment was designed as a comparison of 2 plots with different treatments, namely the control treatment of citronella vegetable pesticide with a concentration of 75% and the biobactericide treatment of B. subtilis with an antagonistic bacterial suspension density of 33 x 104 cfu ml-1. The variables observed were inhibition, disease intensity, weight of harvested dry grain (HDG) per clump, and weight of HDG per plant. The results stated that the biobactericide B. subtilis had a real effect on the development of BLB disease up to an intensity of 14.72% and the development of BLB with citronella vegetable pesticide treatment decreased to 28.97%, the weight of HDG per clump and did not have a real effect on the weight of HDG per panicle.

Abstract

Sesame productivity and seed quality in dryland systems are often constrained by low soil fertility and inappropriate harvest timing. This study aimed to evaluate the effects of Leucaena leucocephala leaf extract applied as a liquid organic biostimulant and different harvest timings on growth, yield, seed quality, and oil content of sesame cultivated under dryland conditions. The experiment was conducted using a factorial randomized complete block design with four extract doses (0, 100, 200, and 300 mL plant⁻¹) and three harvest timings (95, 102, and 109 days after planting). Vegetative growth parameters, yield components, seed physical and physiological quality, and oil content were measured and analyzed. The results showed that increasing extract doses significantly enhanced vegetative growth, capsule formation, seed weight, and total seed yield, with the highest yield obtained at 300 mL plant⁻¹. Harvest timing strongly influenced seed physiological quality and oil accumulation. Seeds harvested at 102 days after planting exhibited the highest germination performance and oil content, whereas earlier or later harvest reduced quality attributes. A moderate extract dose (200 mL plant⁻¹) combined with harvest at 102 days optimized seed quality and oil content, while higher doses favored yield maximization. These findings indicate that synchronizing organic nutrient management with appropriate harvest timing is essential to balance yield and quality in sustainable dryland sesame production systems.

Abstract

This study aims to analyze the influence of climate elements on oil palm productivity at the Pamukan Plantation in Kotabaru Regency, South Kalimantan. The observed climate elements include rainfall, air temperature, and air humidity. This study was conducted using an agronomic survey method and statistical analysis with regression and correlation, using secondary and primary data collected over the past six years (2015–2020). The results show that rainfall, temperature, and air humidity have a significant relationship with fluctuations in oil palm production. Increased rainfall beyond the optimal threshold actually reduces productivity, which is thought to be related to the hilly topography and the dominance of ultisol soils with low infiltration and water retention capacity. High water deficits, such as those experienced in 2015, negatively impact production the following year. Furthermore, increases in temperature and air humidity also show a negative relationship with production, due to disruptions in photosynthesis and plant transpiration. This study indicates that climate change could significantly affect oil palm productivity at the Pamukan Plantation. Therefore, adaptation strategies and plantation management are needed that are more responsive to changing climate conditions to maintain sustainable production.

Abstract

This study examined the morphological and physiological responses of two rice varieties to drought stress to identify adaptive characteristics that support plant resistance. Parameters analyzed included leaf rolling rate, stomatal density, chlorophyll content, proline accumulation, and the number of full and hollow grains per panicle. Results showed that increased drought stress triggered more intense leaf rolling, decreased stomatal density, and reduced chlorophyll content, which negatively affected photosynthesis and yield. Proline accumulation increased significantly, suggesting its important role in osmoregulation and stress tolerance. Variety CIherang (V1) showed better adaptability than Variety Sintanur (V2), characterized by efficient stomatal adjustment and higher proline accumulation. The decreased number of full grains and increased hollow grains at high stress levels confirmed the impact of drought on productivity. These findings indicate that leaf rolling and proline accumulation can be used as indicators for the selection of drought-resistant varieties, supporting the development of adaptive rice in drought-prone areas due to climate change
