Abstract

Post-harvest fungi attacks in storage can reduce the quality of Arabica coffee. The study aimed to determine the level of infection and types of post-harvest fungi in Arabica coffee beans and their quality. The research was carried out at the Phytopathology Laboratory of Plant Pests and Diseases Department and the Seed Technology Laboratory of Agronomy Department, Agriculture Faculty, Universitas Andalas, Padang, from June to August 2021. The infection level of post-harvest fungi was detected using the blotter method. Physical quality was determined based on the percentage of defects, and the quality of the coffee beans was classified according to the Indonesian National Standard (SNI). The samples were taken from three collectors in each of the three central districts of Arabica coffee, West Sumatera province (Solok Selatan, Pesisir Selatan, Lima Puluh Kota) and one sample from Solok Radjo Cooperative as a comparison. The results showed that post-harvest fungi that attacked Arabica coffee beans in West Sumatra belong to the Aspergillus genus, namely Aspergillus niger, A. flavus, and A. ochraceus. The highest post-harvest fungi attack was from Lima Puluh Kota (63.67%), and the lowest was from Solok Radjo (27%). The fungus with the highest infection rate was A. niger (38.83%), and the lowest was A. flavus (0.53%). The best quality of Arabica coffee beans was found in Solok Radjo (quality 3), with a water content that suitable with SNI standards.

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

Weeds that grow around irrigated rice fields can affect the growth of rice plants. This study aims to determine the diversity of weeds in the rice fields of Mulyorejo Village, Malang City, Indonesia. The research was conducted from October - November 2022. The research used a survey with direct descriptive and exploratory methods. The study used a survey method with descriptive and direct exploration methods on an area of 677 m2 at an altitude of 478 m above sea level. Observations were made on weed species, dominance, and diversity index. The results showed that 13 species of weeds were found in the irrigated rice fields of Mulyorejo Village, Malang City, which was dominated by water clover (Marsilea crenata) (20.42%), which is classified as a broadleaf weed. The dominant weed was taro (Alocasia macrorrhizos) (SDR = 5.33). The minor weed is water lactic (Ludwigia decurrens). The rice field weed diversity index is 1.989, classified as moderate. Knowing the types of weed diversity in rice fields in Mulyorejo, it is hoped that it can facilitate the optimal handling process.

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.
