Abstract

Termites are one of the pests in oil palm plantations that can cause physical damage to oil palm plants. This study aims to determine the type and colony of termites in mineral, peat and sandy soils and the effectiveness of their control. This research was conducted at PT. Binasawit Abadipratama located in Danau Seluluk District, Seruyan Regency, Central Kalimantan Province, Tangar Estate from March to April 2023. The research was conducted using a comparative method by comparing termite colonies in mineral soil, peat and with parameters in the form of termite species and the level of attack expressed by scoring, as well as secondary data in the form of termite nest census data in the garden archive to determine the effectiveness of control. The results showed that the largest termite colony was found in mineral soil. Termite species found in all soil types was Macrotermes gilvus, and no indication of termite infestation in oil palm trees. Based on the census data for the past three years, it can be concluded that the control that has been carried out is effective in reducing the termite colony from year to year.

Abstract

Dendrobium orchids are popular plants with high economical value and high demands among the society. The poor quality of orchids is something that can be detected from the cultivation method, including its fertilization. This research aims to discover the impact of the AB mix combination and various types of POC, determine the best type of AB mix combination and POC, and examine the comparison of the AB mix fertilizer combination and types of POC with control fertilizer (AB mix). This research used a Completely Randomized Design (CRD) with a single factor consisting of 5 treatments + 1 control, which are 3 mL/L AB mix plus 150 mL/L POC rice washing excess water, coconut water, kepok banana peel, rabbit urine, cow urine. and control (AB mix). Observation parameters include plant height, stem diameter, number of leaves, number of tillers, length of tillers, and number of roots. Observations were analyzed using Variety Printing at the level of 5% and tested further with the Orthogonal Contrast Test and DMRT at the 5% level. From this research was obtained that the AB mix and POC combination had a significant effect on leaf number parameters. The combination of AB mix and POC rabbit urine was best for the growth of Dendrobium orchids in terms of plant height, number of leaves, leaf length, number of tillers, length of tillers and number of roots. The combination of AB mix and POC was better in terms of leaf number parameters than the control (AB mix)

Abstract

Coffee is a plantation crop with significant economic value, commonly processed into flavorful beverages. Arabica coffee farmers generally face challenges during harvest and post-harvest, particularly with the necessity to pick ripe, red berries. However, during harvest, farmers often do not selectively pick the cherries, resulting in the collection of not only red but also yellowish or green berries. Plant growth regulators (PGRs) are synthetic chemicals that mimic the role of endogenous hormones. This study aims to investigate the interaction between different hormone types and varieties on the ripening of Arabica coffee berries, assess the impact of various hormones on berry maturity, and evaluate the effect of different varieties on the ripening process. The research utilized a completely randomized design (CRD) with two factors: plant growth regulators (PGRs) and coffee varieties. The observed parameters included the number of fruiting nodes per tree, the number of fruits per node, the number of red fruits in the first harvest, the number of red fruits in each subsequent harvest (across three stages), and the weight of green beans per 100 seeds. The analysis revealed no significant interaction between the application of different types of growth regulators (PGRs) and coffee varieties in accelerating the maturation of Arabica coffee berries. Notably, the Yellow Catura variety treated with the growth regulator Ethrel showed a better effect in accelerating berry maturity.

Abstract

Legume Cover Crop (LCC) used in Palm plantations has not yet produced for weed control because there are still large open lands. To prepare LCC seedling of the Mucuna bracteata species, a medium is required that provides good root growth, inter alia, with the addition of organic material derived from various animal debris. This research aims to find out the influence as well as the interaction of type and comparison of the volume of cage fertilizer on the growth of LCC Mucuna bracteata on the latosol soil that has been carried out at the KP2 INSTIPER, Maguwoharjo, Yogyakarta, Yogyakarta and at the Central Laboratory, Instiper on April 20, 2021 to June 30, 2021. This research uses a complete random design (RAL) or Completely Randomized Design (CRD) method that consists of two factors. The first factor is a type of cage fertilizer that consists of three levels, namely cage, chicken and goat fertilizers. The second factor is the comparison of the volume of the soil of the latosol with the cage of 3 levels of 1:1, 2:1, and 1:2 with 10 repetitions. The results of the study were analysed with the analysis of variance prints at the significance level of 5%. The effective treatment was further tested with the Duncan Multiple Range Test (DMRT) using the significance level of 5%. Results of the analysis showed that the treatment of cage fertilizer and the comparison of the soil volume of latosol with cage fertilizer did not have a real interaction and both treatments gave the same effect on the growth parameters of plants, including its length, leaf number, shoots number, top fresh weight, top dry weight, root length, fresh root weight and dry roots of Mucuna brate plant. Cage fertilizer and volume comparison gives the same bet on all the growth parameters of Mucuna bracteata.

Abstract

Soil respiration is an indicator of the level of soil health in both closed systems (forests) and open systems (agriculture). Conversion of land from natural forest to agricultural cultivation needs attention in the field of sustainability, this is done so that the land can continue to be productive. This research aims to obtain information regarding the relationship between respiration and soil properties in land cover of oil palm (Elaeis guineensis), teak (Tectona grandis), and burflower-tree (Neolamarckia cadamba) in INSTIPER's experimental plantation, specifically in SEAT (Stiper Edu Agro Tourism) Ungaran Regency, Central Java. The method used in this research is a modified Verstraete, namely by observing soil respiration directly on the land. Research data shows respiration rates of 100.1, 95.4, and 25.9 mg CO2 m-2 h-1 for oil palm, burflower-tree, and teak respectively. Soil respiration is influenced by land cover in vegetation. Differences in land cover cause differences in soil properties which then influence the rate of soil respiration. The relationship between soil respiration rate and moisture content, pH, and EC is linear positive, while with volume weight it is linear negative.
