Abstract

Research on the effect of Trichoderma sp. In tomato plants on the factors of production is a study carried out for 4 months starting from June to October 2017. The research was carried out at the Green House of the Faculty of Agriculture, Mulawarman University, Samarinda.This research was conducted using a completely randomized design (CRD) with each treatment repeated 3 times. The treatment is Po: Without Trichoderma sp. / Control treatment; P1: 25 g culture of Trichoderma sp. per polybag; P2: 30 g of mushroom culture Trichoderma sp. per polybag; P3: 35 g of mushroom culture Trichoderma sp. Per polybag; and P4: 40 g culture of Trichoderma sp. per polybag As the second factor, tomato varieties include V1: Lentana; V2: Permata and V3: Ratna. The data observed included the number of planting fruit (calculated from the first harvest to the last harvest for each crop); Average diameter of planting fruit and. The average weight of fresh fruit plantations.The results showed that the dose of 40g Trichoderma sp. most effective in controlling F. oxysporum wilt disease on tomato plants, which can increase tomato crop production by 293.48 g. Variety treatment was not significantly different from all treatments. So that there is no interaction between Trichoderma sp. and tomato varieties.

Abstract

The objective of the research was to analyzed rainfall trends from 6 rainfall stations Kajoran, Mendut, Muntilan, Ngablak, Salaman and Tempuran rainfall station in different time scales (monthly, 3-months periodicityand annual). Identification homogenity of the rainfall data period 1986-2016 for Magelang district using Rescaled Adjusted Partial Sums (RAPS) methode. The three non-parametric tests, Mann-Kendall (MK), modified Mann-Kendall (MMK), trend free prewhitening Mann-Kendall (TFPW-MK) and Sen??s slope wereemployed to assess significance of trends and detecting magnitude of trends.The results shows that monthly rainfall have no significant trend using MK, MMK, and TFPW-MK test at 0.05 level significance. Rainfall 3-month based January-February-March (JFM) period Kajoran station have negative significant trend with magnitude 19.4 mm/3-month. Mendut station have positive trend for April-May-June (AMJ) period with magnitude 6.75 mm/3-month. No significant trends at 0.05 level significance using MK trend test were detected in annual rainfall for 6 rainfall stations.

Abstract

The climate in Indonesia is a tropical climate with high rainfall, making Indonesia vulnerable to erosion. In addition to high rainfall, vegetation, slope and soil types also affect erosion. This study aims to determine the Important Value of Species (NPJ), the relationship between rainfall and surface runoff and the mass of eroded soil and the level of erosion hazard at different vegetation densities. Important Value The highest types of the three dominating types in plot I were Schima wallichii 115.12%, Macaranga gigantea 69.38% and Cratoxylum sumatranum 44.69%. Whereas in plot II the highest NPJ value of three types dominates, namely Macaranga gigantea 59.13%, Litsea angulata 39.52% and Aquilaria mallacensis 35.37%. The amount of eroded soil mass that occurred in PUE I was 0.13 tons / ha / year and PUE II was 0.19 tons / ha / year. Simple linear analysis of the relationship between rainfall and eroded soil mass at PUE I has a correlation value (r) = 0.79 with the equation Y = -8.34 + 0.39X, whereas in PUE II the correlation value (r) = 0.90 with the equation Y = -12.96 + 0.56X. The danger level of erosion (TBE) in PUE I and PUE II was very mild (erosion rate <15 tons / ha / year, Bahya Erosion I class with soil solum depth> 90 cm).

Abstract

The study aimed to determine the effect of compost and NPK Pelangi compound fertilizer and their interaction on the growth and yield of beans.The study was conducted in February-May 2016. The location of the study was in Linggang Amer Village, Linggang Bigung District, West Kutai Regency. The research design used was a Completely Randomized Design (CRD) in a 4x4 factorial experiment with 3 replications. Factor I: dosage of compost (B), consists of 4 levels, namely: without fertilizer or control (b0), fertilizer dose of 10 tons / ha or 100 g / polybag (b1), fertilizer dose of 20 tons / ha or 200 g / polybag (b2), fertilizer dose of 30 tons / ha or 300 g / polybag (b3). The second factor: the dose of NPK Pelangi (P) compound fertilizer, consists of 4 levels, namely: without fertilizer or control (p0), 1 g / polybag (p1) fertilizer dose, 3 g / polybag (p2) fertilizer dose, 5 fertilizer dose g / polybag (p3).The results showed that compost treatment (B) had no significant effect on the height of plants aged 10 and 30 days after planting, the number of fruit per plant and the weight of fruit per plant. The effect is very significant on plant height aged 20 days after planting and fruit length. The treatment of NPK Pelangi compound fertilizer (P) had no significant effect on plant height aged 20 and 30 days after planting, fruit length, number of fruit per plant and weight of fruit per plant. Significant effect on plant height at 10 days after planting.

Abstract

In the Samarinda BDLHK Arboretum there is an increasing number of competing rubber species that become competitors against collection plants. Triklopir herbicide is a systemic herbicide that is selective to control broadleaf herbs. The study was conducted on January 17, 2018 until February 21, 2018, while the location of the study was carried out at the Arboretum of the Samarinda LHK Training Center, using materials and equipment such as: Herbicides with trichloride butoxy active ethyl ester: 480 g / l (equivalent to trichloprate: 345 g / l), diesel fuel, water, brushes, buckets, machetes and masks. The trees targeted for poisoning are types of rubber (Hevea brasiliensis). The results showed that the mixture of trichlopir herbicide and diesel fuel fuel reacted faster and statistical tests using randomized block design obtained significant differences in the effect of treatment. For a short time and costs a little more expensive is recommended with a mixture of trichlopric herbicides and diesel fuel, whereas if without a fast and inexpensive time target in terms of cost, the recommended mixture is trichlopric herbicide and water.

Abstract

This experiment aims to: (1) to study of the effect of concentration and application timing of Green Tonik foliar fertilizeras well as their interaction on the growth and yield of cucumber plants; and (2) to find proper concentration and application timing of Green Tonik foliar fertilizer for better growth and yield of cucumber plants.The experiment carried out from March 2016 to May 2016, in the Village of Muara Bengkal Ilir, Muara Bengkal Subdistrict, East Kutai District.  It applied Completely Randomized Block Design with factorial experiment 4 x 3 and three replications.  The first factor was the concentration of the Green Tonik  foliarfertilizer (K) consists of 4 levels, namely: no Green Tonik foliar fertilizer application (k0), 1 ml l-1 water(k1), 2 ml l-1 water(k2), and 3 ml l-1 water(k3). The second factor wasinterval of the application time of Green Tonik foliar fertilizer(W) consists of 3 levels: 5, 10, 15, 20, and 25 days after planting (w1), 7, 14, 21, 28, and 35 days after planting (w2), and 10, 20, 30, 40, and 50 days after planting (w3).Result of the experiment revealed that : (1) concentration of Green Tonik foliar fertilizer application was affected significantly to very significantly on plant lenght at 30 and 45 days after planting, days of plant flowered, number of fruits per plant, diameter of fruit, weight of one fruit, and production of fruits, but no significant on the plant lenght at 15 days after planting, and lenght of fruit.  The highest production of fruit is attained by the 2 ml l-1 water (k3), namely 54,67 Mg ha-1, In reverse, the least production is attained by without Green Tonik foliar fertilizer (k0), namely 24,00 Mg ha ̵ ¹; (2) interval of Green Tonik foliar fertilizer application time was no significant on the plant lenght at 15 and 45 days after planting, days of plant flowered, number of fruits per plant, lenght of fruit, diameter of fruit, weight of one fruit, and production of fruit, but affected significant on the plant lenght at 30 days after planting; and (3) interaction between concentration and application timing of Green Tonik foliar fertilizer was no significant on the all parameters observed.
