Abstract

Termites have a great potential to cause damage to plants and other woody materials because these insects live in colonies. Termites' preferences and potential for harm vary depending on the species. Surveys related to termite species, estimates of damage that occurred, as well as preferences of plants and woody trees attacked in the Riau Islamic University Area were carried out as an initial step to avoid the impact of a greater termite attack. The survey results showed that termites were found in 9 of the 25 plots observed, namely Fisipol (3), Law (3), PKM Building (1), FKIP B (1), Mosque (1), Agriculture (3), Experimental Gardens (2), Student Dormitory (14), and Postgraduate (4). The types of termites that attack the Riau Islamic University area were obtained as many as four different termite species, namely Microcerotermes sp. (Family: Termitidae), Macrotermes sp. (Family: Termitidae), Schedorhinotermes sp (Family: Rhinotermitidae), and Coptotermes curvignathus (Family: Rhinotermitidae). Captotermes is one of the main pests in the Riau Islamic University area because it has been known to attack several plants for a long time. Laboratory tests using the fungus Metarhizium anisopliae showed the potential to cause mortality in termites at a spore density of 1.65 x 108 with a spore viability of 82.8%, resulting in a death time of 1.65 x 108. The best was 1.50 days and the mortality percentage was 99.17%. The spore density of Metarhizium anisopliae added with 10% zeolite was 3.5 x 107 with 90.3% spore viability (M2) resulting in a death time of 2.50 days and a mortality percentage of 75. .12%. Meanwhile, without treatment, the time of death was 5.25 days and the mortality percentage was 20.00%.

Abstract

Porang plant (Amorphophallus muelleri Blume.) is one of the plants that have the potential to be cultivated in peatlands needed to increase its production. This study aims to increase the growth of smallholder plants on peat media until six months after planting through bulbil size with dolomite treatment. The research type was a 4x3 factorial experiment arranged based on a Completely Randomized Design (CRD). The first factor is bulbil size which consists of four levels, e.g., B1 (5.0 g-7.5 g), B2 (>7.5 g-10 g), B3 (>10 g-12.5 g), B4 (> 12.5 g-15.0 g) and the second factor dose of dolomite consists of three levels, e.g., D1 (2.5 ton.ha-1) D2 (5.0 ton.ha-1) D3 (7.5 ton.ha-1) -1). These two factors resulted in 12 treatment combinations, with three repetitions. Each experimental unit consisted of three plants. Parameters observed were growth power, plant height, stem diameter, crown width, rachis length, number of leaves, number of tillers, and number of tubers formed. The results showed that the application of dolomite could improve some of the chemical properties of peat soil. The bigger the bulbil size, the better the growth of people and the administration of 7.5 tons of dolomite.ha-1 increased several plant growth parameters such as growth power and plant height.

Abstract

The utilization of land that is not corresponding to its capabilities will accelerate land degradation. Therefore, in this study, the land capability was assessed to determine land capability classes and land use directions for applying sustainable agricultural systems in coffee and durian cultivation areas in the Wonosalam region, Jombang, East Java. The procedures included field observations, soil sampling, and laboratory analysis. Soil samples were taken at two depths, 0-30 cm and 30-60 cm, carried out by taking samples at two different points, then analyzed in a composite manner. The results showed that the class of land capability for planting coffee and durian was in class VII, which had a limiting factor in the form of slopes. Limited grazing and nature reserves are the focus of class VII land-use guidelines so that the land use direction follows the characteristics of the nature reserve and the principles of sustainable agriculture. Concerning long-term agriculture, we need to use conservation strategies both vegetatively and mechanically. Thus, the land that is the research site will be able to maintain its carrying capacity and minimize the decline in land quality and quantity on land use in the Wonosalam, Jombang area.
