Abstract

Palm oil (Elaies guineensis Jacq.) belongs to the palm group which produces oil and is used as a raw material for the food and cosmetic industries so that palm oil occupies an important position in Indonesia. One of the obstacles faced in increasing the production of oil palm plants is the attack of plant pest organisms. One of them is the presence of pests. One of the important pests on oil palm plants is the leaf-eating caterpillar, namely the fire caterpillar (Setothosea asigna). Setothosea asigna can cause oil palm plants to suffer leaf damage up to 50%. So that it can cause oil palm plants to lose production up to 78% in the first year after the pest attack and 40% in the second year after the attack. The purpose of this study was to determine differences in population and intensity of pest attacks on two oil palm fields with different plant ages. This research was conducted in Gunung Cahya Village, Buay Rawan District, South OKU Regency. Observations were made by survey methods and direct observation methods (Scan sampling) by calculating the number of populations and determining the intensity of pest attacks. Then the oil palm plants were observed as many as 30 plants/land and the data obtained were carried out by t-test. The results showed that the population and intensity of attack of Setothosea asigna in land 1 was lower than in land 2. In land 1, oil palm plantations had produced good fruit, so treatments such as fertilization and land clearing were routinely carried out. While on land 2 oil palms have not been properly cared for because the plants are in their growth period or TBM (Immature plants) and during their growth period, corn is still planted between plants.

Abstract

Rice (Oryza sativa L.) is one of important crops in current era because the crop produce staple food for more than half of world population. Rice cultivation has been facing many obstacles to reach the expected yield. One the causes is the attack of rice pests causing damages on vegetative and generative stages of the crop, and these would lead to yield reduction. The purpose of this research was to determine the method of cultivating rice plants and arthropods and the level of pest attack. This research was carried out in May 2021 with a survey method on five different rice fields in Bumi Agung Village by interviewing farmers to obtain information about farmers' behavior in rice cultivation and observing insect pests in rice plantations. The results obtained from field practice were the discovery of three pests in rice plants, namely Oxya chinensis, Acrida cinerea, dan Atherigona sp. The control carried out by farmers in controlling pest attacks is in the form of jajar legowo, technical culture such as land management, fertilization, weeding and others which are included in integrated pest control (IPM).From the observational data analyzed that the application of integrated pest control (IPM) has proven to have an impact on reducing pest attacks where out of 5 paddy fields that were observed, the 5th land belonging to Mr. Agus was found to have few insect pests and weeds in his rice fields with an average of 0%.

Abstract

One of the essential factors in crop production is the use of quality seeds. The availability of quality seeds affects the quality and yield. Currently, in the field is that soybean seeds sold by seed stores are seeds that have deteriorated and are stored in unfavorable conditions, causing the quality of the seeds to decline. To continue planting, a technique for improving the performance of soybean seeds is required through matrix conditioning and fertilization. This study aimed to determine the effect of matrix conditioning and fertilization treatment on increasing the growth of soybean seeds stored for two months. This study used a two-factor completely randomized design (CRD) with three replications. The first factor was matrix conditioning media (without matrix conditioning, sawdust, and husk charcoal). The second factor was fertilization (without organic fertilizers and inorganic fertilizers), 100% organic fertilizers, 100% inorganic fertilizers, and 100% organic fertilizers + 50% inorganic fertilizers). The data were tested by using 5% BNT. Variables observed were plant height, number of leaves, leaf dry weight, stem dry weight, root dry weight, and number of root nodules. The results showed that there was an interaction effect between matrix conditioning and fertilization media on the observed variables of plant height, leaf dry weight, and single matrix conditioning treatment that affected the observed variables of root dry weight and number of root nodules in improving seed quality and growth. Keywords: soybean, quality, matrixconditioning, fertilization

Abstract

One of the causes of low sugar production is the quality of sugar cane seeds. Seed quality is one of the factors that determine the success of sugarcane cultivation. Breeding bud chips is a vegetative sugarcane seedling using one-eye cuttings. In addition to nutrients, growth and seed quality are also influenced by growth regulators (ZPT). Atonic (auxin) is able to increase the metabolic rate so that cell development increases and the absorption area of ​​leaves is more which affects the increase in leaf area, and stimulates plant root growth, increasing root absorption of nutrients. The purpose of the study was to determine the growth response of sugarcane seedlings (Saccharum officinarum L.) on the duration of immersion of cuttings in Atonic PGR solution. The study was carried out using a randomized block design with 4 replications, and 6 levels of immersion time of sugarcane cuttings in Atonik PGR solution: P0 = control, P1 = 10 minutes, P2 = 20 minutes, P3 = 30 minutes, P4 = 40 minutes, and P5 = 50 minutes. Testing the data with an orthogonal polynomial test. Research conclusions: (1) For every 10 minutes of immersion time of sugarcane cuttings in Atonic PGR solution: (a) the length of the sugarcane seeds increased by 0.379 cm, and (b) the dry weight of the sugarcane seeds increased by 0.007 g. (2) The duration of immersion of sugarcane cuttings of one bud in Atonic ZPT solution did not show any effect on the percentage of budding cuttings of sugarcane cuttings, the number of leaves, stem diameter, and wet weight of seedlings. Keywords: Sugarcane Plant Seeds, Soaking Time, ZPT Atonic Solution

Abstract

The black soybean plant is one of the food crops whose existence is very necessary for the consumption of the population in Indonesia. People of Indonesians very consumted with sweet flavorings, but do not want to make the risk of diabetes. Black soybeans in addition to being the main ingredient in making sweet soy sauce, also has benefits for mothers who are breastfeeding because of the rich nutritional content of benefits for the growth and development of the baby. Due to the high demand for black soybeans, the government encourages farmers to further increase the production of black soybeans. One of the government's efforts is to release the Detam Prida 3 and Detam 4. However, in these production efforts, there are pest to the decline in the quality and quantity of production caused by pest attacks of black soybean plants. The purpose of this study was to determine the pattern of pest infestations on soybean plants both in the vegetative and generative. In this study using Detam Prida 4, observations were carried out every day from the vegetative to the generative. Observations are carried out daily after planting. The observation made is to determine the pattern of attack infestation, which is not harmful to the current condition (+), harm at the time condition (++), and very dangerous at the time (+++). From the results of this study the pests that attack black soybeans in the vegetative phase are seed flies, armyworms, and aphids that attack from the seventh day after planting and pests that attack black soybeans in the generative phase, namely leaf roller caterpillars and green ladybugs that attack 30 days after planting.
