Abstract

The health of the teak tree can be affected by damage caused by pests and environmental factors. This study aims to determine the health of the teak tree in teak production forest areas at RPH Sukorame KPH Mojokerto, East Java, Indonesia. The method used was the forest health monitoring (FHM) method. The sample was chosen by using a cluster plot system with a total sample of 216 teak trees. Parameters observed were symptoms of damage and its causes, type of damage and damaged parts of the teak tree, height and diameter, tread quality, and tree health analysis. The results showed that the health level of the teak tree in the teak production forest area of RPH Sukorame, KPH Mojokerto, East Java, was included in the health category with a Cluster plot level index (CLI) value of 4.36 - 4.51. The damage to the stand was caused by the attack of armyworm (Hyblaea puera), termites (Schedorhinotermes sp), and other factors. The productivity level of the area could have been more optimal, with a branch-free stand height of 0-5 m and a diameter of 16-20 cm: grumusol and grumusol sandy soil with a pH ranging from 5.8 to 7.0. Forest management is needed so that the teak tree can achieve optimum productivity.

Abstract

One of the control techniques for the brown planthopper or BPH (Nilaparvata lugens Stal) is resistant varieties. This study aimed to determine the resistance level of several rice varieties (Oryza sativa Linnaeus) to the BPH of the Karawang Population. The study was located at the Entomology Laboratory, Center for Predicting Plant Pest Organisms (BBPOPT) Jatisari, Directorate General of Food Crops, Ministry of Agriculture, Indonesia, from July to August 2022. The study was conducted in a Completely Randomized Design (CRD) with ten treatments and five replications. The treatment was in the form of different rice varieties (Pelita, Inpari-33, Inpari-47, Inpari-48, Ciherang, Cilamaya Muncul, Mapan, Situ Bagendit, M-400, IR-64). Parameters observed were spot area, spot area conversion, and determination of resistance. The results showed that the resistance of some of the tested rice varieties to BPH of the Karawang population was classified as moderate to moderately resistant. Inpari-47, Inpari-48, IR-64, M-400, Inpari-33, Cilamaya Muncul, and Situ Bagendit are moderately resistant, while Mapan, Ciherang, and Pelita have moderate resistance. The results of the honeydew test can be compared with other resistance test methods.

Abstract

Brown planthopper or BPH (Nilaparvata lugens Stal, Hemiptera: Delpachidae) is a significant pest that is a severe problem to rice plants in various places, including Bogor District, East Java Province. Resistance of several varieties of rice to BPH of Bogor Population has not been reported. One method to determine a variety's resistance is the honeydew test. This study aims to determine the resistance of several rice varieties to BPH of Bogor population. This study used six different varieties as treatments, and carried out in five replications. Those varieties were Pelita, Mapan, Situ Bagendit, Ciherang, Inpari-33, and IR-64. The observations were made on the area of honeydew spots produced by BPH after consuming sap of rice plant. This research showed that the Situ Bagendit variety was relatively resistant to BPH of Bogor population. The Mapan and Pelita varieties were quite susceptable, while Inpari-33, Ciherang, and IR-64 were moderate. The region of origin where BPH grows and the testing procedure can affect the resistance category of one variety.

Abstract

Anthracnose is an important disease in red chili caused by Colletotrichum capsici which can reduce productivity by up to 65%. Controlling using indigenous epiphytic yeasts has never been done. The study aimed to determine the ability of indigenous epiphytic yeast isolates to control C. capsici on red chili. The study was carried out at the Phytopathology Laboratory, Faculty of Agriculture, Universitas Andalas, from August 2019 - April 2020 in vitro and in vivo. The study used a completely randomized design (CRD) which consisted of 6 treatments with five different isolates (4 isolates from fruit and one from leaves) and a control. Parameters observed were macroscopic and microscopic characteristics of yeasts, C. capsici colony area, disease incubation period, and anthracnose symptoms. The results showed that the five epiphytic yeast isolates could suppress the growth of C. capsici, inhibit colony expansion between 27.09 – 59.11%, extend the incubation period for one day, and inhibit the expansion of anthracnose symptoms between 52.30 – 62.64%. Epiphytic yeast isolate KB1 derived from fruit has the highest inhibition.

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.
