Abstract

Light traps are a way to detect early pest attacks in the field. A light trap is a device used to catch or attractinsects. Functions to determine the presence or number of insect populations on plantation land. The use oflight traps as an environmentally friendly alternative for pest control, insect attraction to color is one way ofadapting insects in nature. Insect adaptations aim to protect themselves from predators. This research wasconducted at PT. X Kebun Afdeling 4, North Sumatra. This research aims to determine the time and lightintensity in the light trap application that is most effective in controlling bagworm imago. The method used isthe descriptive method, consisting of 3 different times, namely 19.00-21.00 WIB, 23.00-01.00 WIB, and 04.00-06.00 WIB. The parameter observed was the number of trapped bagworm (Metisa plana) imago. From theresearch results, the time for applying light traps at 04.00-06.00 WIB is the time for applying light traps thatis effective in controlling imago of bagworms (Metisa plana) with a total catch of 242 individuals during 10days of research at PT.

Abstract

Oil palm is an important asset of Indonesian plantations. Problems in cultivation are mainly bagworm (Metisa plana) attacks that reduce growth by eating oil palm leaves and reducing yields. To overcome this problem, the application of bioinsecticides such as Bacillus thuringiensis (Bt) is a substitute for chemical pesticides. Bt produces toxic crystalline proteins that target the insect's gutreceptors, so it does not harm non-target organisms. The research was conducted in Teluk Panji IV Village, North Sumatra. The research design used a completely randomized design with five treatments and four replicates for seven days. The treatments were the use of Bt at concentrations of 0, 5, 10, 15, and 20 grams per liter. This study aims to assess the dose of Bt application as a sustainable pest management strategy in oil palm cultivation. The results showed that the treatment of Bt doses (0.5 g/L, 10 g/L, 15g/L, and 20 g/L had no significant effect on each observation variable. Symptoms of bagworm infestation included decreased appetite and movement within 24 hours after application, followed by discoloration and dark brown discharge between days 3 to 5,which eventually led to death and decay. Although the treatment results were not significant, the use of Bt bioinsecticide can still be used to control bagworm pests because some bagworms in this study died There were 51 caterpillars with the highest mortality at 20 g/l concentration.

Abstract

Pestalotiopsis sp. is one of the important pathogens in plantation crops in Indonesia that can cause significant damage, especially in oil palm and rubber plantations. This paper aims to examine the characteristics, distribution patterns, and impact of Pestalotiopsis sp. on various plantation crops, with a focus on rubber plants. Morphologically, Pestalotiopsis sp. It has an asexual form in the form of a pycnidium and a sexual form in the form of a peritis. Symptoms of the attack are characterized by the presence of spots on the leaves that develop into blight and can lead to excessive defoliation. The research method used in this writing is a journal review. The distribution pattern of pestalotiopsis sp. in rubber plants includes spatial, vertical and temporal distribution. A deep understanding of the epidemiology and patterns of the spread of the disease is key to developing effective control strategies to minimize the impact of losses on plantation crop production.

Abstract

The research was on ex-coal mining land located in Kintap District, Tanah Laut Regency, South Kalimantan Province, and the oil palm plantation located in Kelumpang Selatan District, Kotabaru Regency, South Kalimantan Province. The increase in palm oil production in Indonesia is followed by increasing in the area of oil palm plantations every year. Arable land is limited, and a ban on opening new land for oil palm plantations affects oil palm companies to utilize existing marginal land for oil palm plantations. The research aims to find out and compare the growth and production of mature oil palm trees planted on ex-coal mining land and original mineral land. The study was conducted from March to April 2023 and used agronomic methods by determining sample blocks and collecting primary and secondary data. That data was obtainable by measuring trees in 2 ex-coal mining blocks and original mineral blocks. Each block consists of 30 sample trees. The data obtained were then analyzed using the t-test at a significance level of 5%. The results showed the stem circumference, number of fronds, and length of fronds on ex-coal mining land were significantly different from the original mineral land, and stem height, number of leaves, petiole width, petiole thickness, and production on ex-coal mining land didn’t show significant differences from the original mineral land.

Abstract

Oil palm productivity cannot be separated from where the seeds come from. The success of a nursery is seen from the quality of the seeds produced. One factor that influences seed growth is the fertigation system. One of the renewable fertigation systems is the drip fertigation system. This research aims to analyze the comparison of vegetative growth in various plot conditions in the drip fertigation system by actually comparing the results of measuring the vegetative growth of seedlings with the drip fertigation system. The research was carried out at PT. Bumi Permai Lestari Perkebunan Bukit Intan Estate (BINE) is located in Ds.Terentang, Kec.Kelapa, West Bangka Regency, Bangka Belitung Province. This research was carried out from April 2023 to October 2023. The research was carried out using quantitative analysis methods as primary data for the research data which was analyzed using the one-way variance test method at a 5% level followed by DMRT test. The results showed that plots with flat elevations and normal distances had superior vegetative growth compared to seedlings in plots located far from reservoirs and plots with sloping elevations. It was concluded that the location and topography of the main nursery plot had a real (significant) influence on the vegetative growth (seedling height, number of leaves, and stem circumference) of oil palm seedlings with a drip fertigation system, where the sloping topography had an unfavorable influence on the growth of oil palm seedlings.
