AbstractMonoculture cultivation system has impact on various biotic  surrounding in it.  Palm oil cultivation with intercropping system started  to be popular to avoid environment damaged. Intercropping cultivation between palm oil and other plant was possible in existing both intraspecific and interspecific competation. Various form of this competation was needed to be learned. The compatible variables to measure these competation forms is Land Equal Ratio (LER) that able to compare the benefit between monoculture and multicultural cultivation system. The aim of this research was to determine the LER of multicultural cultivation between palm oli and rubber tree. this research had been held in February – July 2016 at Wanareja Village, Rimbo Ulu Sub-District, Tebo Regency. Survey method was use in this research, and the location above was purposely  sampled suitable with the needed data. In the other word one reason of this location to be sampled was the only area that showed the existing of multicultural cultivation system especially between palm oil and rubber tree. There were several farmer characteristics to be sampled as a respondent e.g. : 1). Farmers that has no cooperation with enterprise ; 2). The farmer has at least one hectare of land; and 3). Show plant at the minimally age of 5 years. The result of this research showed that the production   of Monoculture cultivation was higher than multicultural cultivation system, but it had 1.5 of LER so it indicated that the multicultural cultivation system give 50% higher benefit than Monoculture cultivation system. keywords: Monoculture, multicultural, Intercropping AbstrakPertanaman monokultur diyakini akan berdampak terhadap keragaman makhluk hidup yang berada pada areal tersebut.

Abstract

Low cocoa productivity, especially in smallholder plantations, is caused by soil conditions showing symptoms of "soil fatigue", increasing old plants, attacks by cocoa fruit borers (PBK), and vascular wilt (VSD), and fertilization that is not in accordance with the dose. This study aims to determine the intensity of attacks by cocoa fruit-sucking ladybugs (Helopeltis sp.) on smallholder plantations in Betung Village, Kumpeh Ilir District, Muaro Jambi Regency. This research was conducted from March to August 2024 on smallholder plantations in Betung Village, Kumpeh Ilir District, Muaro Jambi Regency. The method used in this study is the survey method. The procedure for determining the location of the study was carried out by purposive sampling. A total of 2 plantation locations became research areas with a land area of 1 ha each. The distance between the two locations is ± 1 meter. The observation method is carried out by transect or surrounding the garden according to the predetermined direction of the track. The number of plant populations at locations 1 and 2 was 600 stems (>100) so 15% of the sample plants were taken so that the number of sample plants taken was 15% of the 600 plants = 90 plants. The variables observed in this study were the type of clone and age of the plant, the number of shade plants and light intensity, the number of main branches of the cocoa plant, agronomic measures, temperature and humidity, production estimates, the level of ladybug pest attacks, the intensity of ladybug pest attacks on each plant. The results showed that cocoa plants were cultivated with a polyclonal system using MCC 02, S1 and S2 clones. The age of the plants varied with a range of 7 to 15 years. The permanent shade used in cultivation was the duku plant with a planting distance of 10 x 10 m. Standard agronomic actions have been carried out on plantation 1 and plantation 2, only the maintenance intensity is much better on plantation 1. The intensity of cocoa fruit sucking ladybug pest attacks on the people's plantation in Betung Village, Kumpeh Ilir District, Muaro Jambi Regency in plantation 2 was 53.08% and on plantation 1 was 22.38%. The level of fruit sucking ladybug pest attacks on the people's plantation in Betung Village, Kumpeh Ilir District, Muaro Jambi Regency in plantation 2 was 63.37% on plantation 1 was 35.18% 1. The level of attack and intensity of fruit sucking ladybug pest attacks in this study were included in the moderate category for plantation 1 and severe for plantation 2. Agronomic actions, level of attack, intensity of fruit sucking ladybug pest attacks caused differences in production, plantation 1 was 842.4 kg/ha/year and in plantation 2 was 576 kg/ha/year
