Abstract

Utilization of household waste as organic fertilizeris an easy solution, cheap and effective because ithasvery largerole and benefits in terms of environment, sustainable agriculture/food security and socio-culture.  The research consisted of two stages: the first was makingorganic liquid fertilizer (OLF) of household waste, followed by laboratory analysis to know OLF quality with reference tominimum technicalrequirements of OLF and compound biochemical fertilizer based on Minister of AgricultureRegulation No. 70/Permentan/SR.140/2011 and the second was OLFapplicationon shallot Tuk Tuk variety.  The factorial experiment 2 x 3 was arranged in Randomized Complete Block Design with six times replication.  The first factor wasthe OLF dose, consisted of two levels:500 and 1 000 mL polybag-1, while the second was  OLFconcentration, consisted of three levels: 0, 50 and 100 mL L-1.  Data were analized by Analysis of Variance.The results showed that the OLF contained nutrients quite complete (total N and micro nutrients), negative pathogenE. coli and Salmonella sp., very low metalscontent and higher  number of fungi than minimum technical requiremnts ofOLF,  although  some parameters (total N, micro nutrients and number of bacteria) were lower.  The effect of dose, consentration of OLF and the interaction were not significantly difference on variables observed.The quality of organic liquid fertilizerof household waste was sufficient to meet therequirements of Minister of Agriculture Regulation.   A dose of 500 mL polybag-1witha concentration100 mL L-1tended to give abetter effect on the growth and yield of shallot bulb.

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.

Abstract

This study aims to determine the farmers’ perception about wanamina silvofishery, comprehend the feasibility of Wanamina silvofishery and the strategy of developing Wanamina silvofishery in Muara Badak subdistrict.The results of this research are as follows; The farmers’ perception about Wanamina silvofishery is on the average score of 772, signifies high category. This means their perceptions on Wanamina silvofishery are positive and the farmers support wanamina silvofishery as a farming system that can preserve the environment. Meanwhile, farmers’ perception that believe Wanamina silvofishery increases income is 332, signifies moderate category. This means Wanamina silvofishery still cannot increase the farmers’ income. The results of business analysis show the NPV (Net Present Value) of Rp. 17.643.973which signifies feasible. The value of IRR (Internal Rate of Return) is 15% which signifies feasible, and the value of NBCR (Net Benefit Cost Ratio) is 1,5 which signifies feasible. Overall, the Wanamina silvofishery business in Muara Badak subdistrict is feasible to develop. The result of SWOT analysis resulted on the development strategies of Wanamina silvofishery are as follows: (1) develop the economic improvement programs and added value for Wanamina farmers; (2) Strengthen the capacity of the Fisheries Office and the partnerships among stakeholders; (3) Proper management of seeds and mangrove plants in Wanamina silvofishery; (4) Improve the facilities and infrastructure to increase the performance of Wanamina silvofishery; (5) Develop technical manuals in cultivating Wanamina silvofishery; (6) Develop pilot project of wanamina silvofishery as a community pilot; (7) Increase the quality of Fisheries PPL especially in the field of aquaculture; (8) Increase public awareness about Wanamina silvofishery through counseling and socialization.Based on the aforementioned results, the researcher suggests to conduct a more in-depth study of Wanamina silvofishery, organize comprehensive programs that involve all parties; government, private and farmers, and establish a model silvofishery that becomes a reference for farmers as excellent silvofishery management.

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.
