Abstract

The diversity of predatory insects was studied in recent and old lands in Dharmasraya from April to July 2017. The objective was to study the diversity of predatory insects between recent and old plantations of oil palm. The sampling locations were Pulau Punjung, Timpeh and Koto Besar Districts. The method used in the study was Purposive Random Sampling. Insects were collected using the insect net and chemical knockdown. Identification was carried out at the Laboratory of Insect Bioecology, Faculty of Agriculture, Andalas University. Diversity and evenness of predatory insects in several oil palm plantations in Dharmasraya Regency was classified as medium, namely (H '<1), and (E <0.76). There were 11 families and 6 orders found. The abundant family was formicidae.

Abstract

Cameroon and Angola, accession palms oil, were two plants with different flower architectures such as bunch size, bunch length, number of spikelets and flowers, and volatile compounds produced. The difference in flower characteristics was thought to affect the presence of flower-visiting insects in the two palm oil accessions. The study aimed to determine the insects that visit Cameroon and Angola palm oil flower accessions. Insects that visit flowers were collected directly, using yellow pan traps, swing nets, and aspirators. Collected flower-visiting insects were identified as species. Diversity and evenness were calculated using the Shannon diversity index and the Simpsons’ evenness. The total number of flower-visiting insects collected was 2039 individuals. In the Angola accession, 150 individuals were found consisting of 5 orders, 10 families, and 14 species. Insects that visited Cameroon’s accession of palm oil flowers were 1889 individuals consisting of 8 orders, 16 families, and 22 species. Angola accessions’ diversity and evenness index were higher than Cameroon’s, namely 1.50; 1.14 and 1.14; 0.52. Flower-visiting insects that act as pollinators were Elaeidobius kamerunicus, Pyroderces Sp, and Thrips hawaiiensis.

Abstract

Organic matter has a very important role in determining the level of soil fertility, especially in marginal soils such as Oxisol which is widespread in Indonesia. Organic matter that is commonly used requires large amounts and has the ability to react relatively slowly in the soil. Therefore, it is necessary to make efforts to obtain organic material that reacts quickly in the soil, such as humic material extracted from lignite. In this study, cocoa (Theobroma cacao) was used as an indicator plant. Cocoa is one of the plantation commodities that has a fairly important role in the national economy, especially as foreign exchange for the country and has a relatively stable price. This research was conducted in the form of a pot experiment using a 2 x 4 x 4 factorial design with 3 replications in a divided plot design, so that 32 treatments and 96 experimental units were obtained. From the research results obtained data that the addition of humic materials and compost up to a dose of 4% C-organic combined with artificial fertilizers can increase the availability of nutrients for cocoa seedlings in Oxisol. The best dose of each treatment was the addition of humic material at a dose of 4% C-organic combined with artificial fertilizer 50% of the recommendation and the addition of compost at a dose of 4% C-organic combined with artificial fertilizer 50% of the recommendation. The addition of organic matter can reduce the use of artificial fertilizers up to 50% of the recommendation. The addition of humic materials from unproductive coal can increase the availability of nutrients in Oxisol. Unproductive coal has the potential to increase Oxisol soil fertility.

Abstract

Both oil palm plantations boerdering forests and oil palm plantations bordering rubber plantations were studied using purposive random sampling with pit fall traps, sweep nets and yellow pan traps. Species biodiversity was analyzed using the Shanon-Wienner index and the Simpson index. The dominant species was determined using the Important Value Index. This study found 1,683 individuals, 7 orders and 18 families of predatory and parasitoid insects. The Shanon-Wienner diversity index was 2.78 for oil palm plantations adjacent to forest and 2.62 for oil palm plantations adjacent to rubber plantations. While the Simpson diversity index was 1.00 for oil palm plantations adjacent to forest and 0.94 for oil palm plantations adjacent to rubber plantations. The Order Hymenoptera Family Formicidae had the highest Important Value Index (0.58 for oil palm plantations bordering forest and 0.62 for oil palm plantations adjacent to rubber plantations).

Abstract

Information on the type of OPT that attacks plantation commodities in Buton Regency is incomplete, even though the data can be the basis for mitigating attacks and controls if the plants have been attacked. For this reason, research was conducted to identify the type and distribution of pests in plantation crops, especially in cocoa, cloves, cashew, pepper, and coconut commodities. They analyzed the damage caused by OPT in plantation crops, especially in cocoa, cloves, cashews, pepper, and coconut commodities, and determined alternative solutions for control and prevention. Observations were made in several villages in several sub-districts in Buton Regency. Direct observations were made on the specified land, and interviews with farmers and various related parties were conducted. To get OPT-type data and damage levels. OPT that attacks cashew consists of two types of pests and one disease. The level of damage OPT in the categorized category of guava plants. The level of damage to the pest on the categorized cashew was low. In coconut commodities, found OPT from three types of pest groups, namely Orycter Rhynocheros, Aspidiotus Destructors, and Pestalotia sp. The level of attack of the three pests was categorized as low. Cocoa was the commodity mainly attacked by OPT, consisting of 4 types of pests and four types of diseases. Fruit rot (Phytophthora palmivora) and stem cancer (Phytophthora palmivora) had a heavy attack rate in all cocoa-producing districts in Buton Regency.
