Abstract

Oil palm empty fruit bunches (OPEFB) can be processed into liquid smoke through pyrolysis. This study aimed to obtain the best concentration of unpurified liquid smoke from OPEFB in inhibiting the growth of the fungus of Ganoderma boninense. OPEFB samples were obtained from PT. Citra Putra Kebun Asri and G. boninense were collected from Muara Teweh Plantation. The study was conducted in 2 stages; Analysis of liquid smoke from pyrolysis using the GC-MS method at the Organic Chemistry Laboratory, Faculty of Mathematics and Natural Sciences, Gadjah Mada University; and testing the inhibition of liquid smoke on G. boninense in vitro at the Basic Plantation Cultivation Laboratory, Hasnur Polytechnic, and the Microbiology Laboratory of Plantation Products Processing Technology, Muara Teweh Polytechnic. This study was conducted in a completely randomized design with four treatments and six replications. The treatment was the difference in concentration of liquid smoke (1 ml/AC1, 2 ml/AC2, 3 ml/AC3, and control/AC0) in the planting medium, potato dextrose agar (PDA). The results showed that the average yield of unpurified liquid smoke from OPEFB was 34.5%, containing 49.28% acetic acid, 11.57% methyl alcohol, and 9.10% phenol. Application ? 2 ml liquid smoke in PDA completely inhibited G.boninense's growth in vitro, starting three days after application.

Abstract

Termites are classified as insects that destroy trees and other organic materials containing cellulose, including pine trees. The species and attack intensity of termites on pine trees in the protected forest of Nagari Talang Babungo, Solok District, West Sumatra Province, is unknown. This study aimed to determine the type and intensity of termite attacks on pine trees in the protected forest of Nagari Talang Babungo, Solok District, West Sumatra Province. This research was conducted by survey method with direct observation and graveyard test techniques. Based on the results, it was found that around 7.8% of pine trees in the Nagari Talang Babungo Protection Forest, Hiliran Gumanti sub-district, Solok Regency, West Sumatra Province, were attacked by termites Nusitutermes sp, which was indicated by the presence of termite galleries on the trunks and bases of the stems. The intensity of the termite attack was relatively low, with a percentage of lose weight by using graveyard test was 17.7%.

Abstract

Rhinoceros beetle (Oryctes rhinoceros) is the primary pest of oil palm (Elaeis guineensis Jacq.). Applying oil palm empty fruit bunches (OPEFB) and various other organic materials to cultivated land is assumed to support the growth of rhinoceros beetles. The study aimed to determine the suitability of organic matter as a place for rhinoceros beetle larvae to live. The research was carried out experimentally using a completely randomized design (RBD) with eight treatments and four replications. The treatment was in the form of OPEFB, rice husk, sawdust, OPEFB + rice husk, OPEFB + sawdust, OPEFB + rice husk + sawdust, and OPEFB + rice husk + sawdust without composting. The results showed that the growth of rhinoceros beetle larvae tended to be best on an organic material combination of OPEFB + rice husk + sawdust without being composted. Meanwhile, rice husk is the most unsuitable organic material for developing rhinoceros beetle larvae. Applying organic matter to palm land should be composted beforehand to reduce Rhinoceros beetle infestation.

Abstract

Atrazine 500 g/l is a selective herbicide that can be applied during pre- or post-growth of corn. This study aimed to determine the effective level of dosage in controlling weeds in the corn planting area and its impact on growth and corn yields. The study was conducted at the Experimental Garden of Universitas Lampung, South Lampung, and the Weed Laboratory of the Faculty of Agriculture, Universitas Lampung, from August to November 2022. The study used a Randomized Block Design (RBD) with seven treatments and four replications. The treatment consisted of 5 herbicide doses (Atrazine 500 g/l (500, 750, 1,000, 1,250, and 1,500 g/ha), manual weeding, and control. The results showed that Atrazine 500 g/l at doses of 750 - 1,500 g/ha effectively controlled the growth of total weeds, broadleaf and grass weeds, Digitaria ciliaris, and Richardia brasiliensis. While at doses of 500–1,500 g/ha, it effectively controlled Eleusine indica, Cleome rutidosperma, and Commelina benghalensis. Those doses did not poison, and did not inhibit growth, and the yield of maize.

Abstract

The density and attack rates of Spodoptera frugiperda have been reported in various maize cultivation in Indonesia, but there has never been a report in Sijunjung District, West Sumatra. The research was conducted to study the attack level, density, and distribution of S. frugiperda in Sijunjung District. The study was carried out in March -May 2023 using a survey method in 8 sub-districts in Sijunjung District. The results showed that S. frugiperda had spread and attacked maize crops evenly in Sijunjung District, but the attack rate (26.96%) and density (0.24 individuals) were low. The highest attack was found in Nagari Guguak (88.7%). The high or low rate of attacks is influenced by differences in varieties, planting ages, and maize cultivation techniques. Meanwhile, the density is more influenced by age differences.

Abstract

Integrated Pest Management (IPM) is a pest control method that combines several control techniques by considering ecological, economic, and sociological consequences. Management efforts with IPM principles can be conducted by cultivating healthy plants and entomopathogen application. This study examined the IPM package's success for controlling fall armyworm (Spodoptera frugiperda) in maize field. This research was conducted in a farmer's maize plantation in the West Pasaman District from August to December 2021. The study used a Randomized Block Design (RBD) which consisted of three treatments and five replications. The treatments were different cultivation techniques using IPM, Non-IPM, and control. The variables observed were the population of S. frugiperda (individual/plant), attack rate (%), attack intensity (%), cob weight (g/cob), and farming cost (IDR). The results showed that the IPM and Non-IPM maize cultivation techniques had no different effect on S. frugiperda, especially survival stage, attack rate, intensity, and yield. However, this effect was higher than the control. In addition, the economic benefits of cultivation with IPM were higher than non-IPM. Therefore, this IPM package can be recommended for controlling S. frugiperda because it is also economically profitable and environmentally friendly.
