Wrong one area for the development of the Siam Banjar orange in South Kalimantan is located in the Barito Regency Kuala. As one of the agricultural commodities, Siam Banjar orange has high enough risk, so it needs good management in terms of this is called risk management. This study aims to identify Siam Banjar orange distribution channels, identify and analyze risks that occur in the supply chain distribution channel of Siam Banjar oranges, as well measure the risk on each member of the supply chain and search for those members that have the greatest risk. The data analysis method used is descriptive analysis, methods Analytical Network Process (ANP) and Weighted Failure Mode and Effects Analysis (WFMEA) to analyze the risks that occur and find members supply chain that has the greatest risk in the supply chain distribution channel Siam Banjar oranges in Barito Kuala Regency. From this research, it is found that the distribution channel of Siam orange Banjar in Barito Kuala Regency generally consists of farmers and traders, collectors, wholesalers and retailers and applied through five structures. A more accurate risk analysis result with the WFMEA method, value WRPN obtained for price risk (151.424), transportation risk (52.875), risk supply (52.380), quality risk (51.858), production risk (50.165) and risk environment (5.888). The results of the priority assessment of the Siam orange supply chain actors Banjar with the ANP method, namely farmers (0.371), traders (0.128), wholesalers (0.360) and retailers (0.142). Thus, members of the supply chain farmers who have the greatest risk.</p> <p><strong>Keywords:</strong> Risk Analysis, Supply Chain, Siam Banjar Orange, Analytical Network Prosess (ANP)</p> Karimal Arum Shafriani Hartoni Hartoni ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2021-06-30 2021-06-30 7 1 10 16 10.20527/twj.v7i1.103 Growth Response of Edamame Soybean (Glycine max (L.) Merr.) with Application of Urea and Rhizobium Biofertilizer on Peat Soil Media http://twj.ulm.ac.id/index.php/twj/article/view/100 <p>Edamame is a type of soybean that is consumed in an immature period. High demand for market exports especially to Japan, must be balanced by maximizing production with the use of marginal lands. One of marginal lands is peatland which might be used as growth media for edamame with Urea and <em>Rhizobium </em>biofertilizer application to support its growth. The recent study aimed at analyzing the combination of Urea and <em>Rhizobium </em>biofertilizer on the growth of edamame on peat soil media. The experiment was laid out in. Completely Randomized Design (CDR) with two factors. First factor was Urea dosage: p<sub>1 </sub>= 50 kg ha<sup>-1</sup>, p<sub>2</sub> = 150 kg ha<sup>-1</sup>, p<sub>3 </sub>= 100 kg ha<sup>-1</sup>, p<sub>4</sub> = 200 kg ha<sup>-1</sup>. The second factor was <em>Rhizobium </em>biofertilizer treatment: r<sub>0</sub> = without <em>Rhizobium </em>biofertilizer and r<sub>1</sub> = <em>Rhizobium</em> biofertilizer 8g kg<sup>-1</sup> edamame seeds. All combination was repeated 3 times with 3 polybags of them, so that there were 72 plants in total. The results showed that there was a response between application of Urea and <em>Rhizobium </em>biofertilizer have a significant effect on the observed parameters, that is plant height (cm), number of trifoliate leaves (straind), shoot dry weight (g) and root dry weight (g). The result showed that the application of Urea 50 kg ha<sup>-1</sup> with <em>Rhizobium </em>biofertilizer increased plant growth of edamame on peat soil.</p> <p><strong>&nbsp;</strong></p> <p><strong>Keywords: </strong>Biofertilizer, Edamame soybean, Fresh vegetable, Wetland</p> Wita Purnama Sari Dewi Erika Adriani Chatimatun Nisa ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2021-06-30 2021-06-30 7 1 17 24 10.20527/twj.v7i1.100 Effect of Fish Amino Acid Application on Growth and N-uptake in Plants Rice Using The System of Rice Intensification Method http://twj.ulm.ac.id/index.php/twj/article/view/91 <p>Rice is the main rice crop which is used as the staple food of most Indonesians. Rice production in Indonesia cannot be separated from inorganic fertilizers which have a bad impact on the environment, so it is necessary to carry out a revolution, one of which is the SRI method. The addition of FAA organic matter originating from fish sorted by fishermen which have no selling price is used as a substitute for inorganic fertilizers. This study aims to determine the effect of FAA application on growth and N uptake in rice plants using the SRI method and to determine the best dose of the effect of FAA application on growth and N uptake in rice plants using the SRI method. This research was conducted in December 2019 - April 2020 at the Greenhouse of the Agroecotechnology Department, Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. The design used was a one-factor Completely Randomized Design (CRD), with treatment f0 (control / without FAA application), f1 (1 mL FAA / L), f2 (3 mL FAA / L), f3 (5 mL FAA / L) , and f4 (7 mL FAA / L). The treatment was repeated 5 times, to obtain 25 experimental units. Observation parameters in the study were plant height, number of tillers, and N uptake of rice leaves. The results showed that the application of FAA with a dose of 1 mL FAA / L was able to increase the height of rice plants by 5.5%, produced an average number of tillers of 14 tillers, and was able to increase nitrogen uptake by 9.6% in rice plant leaves.</p> Jumar Jumar Riza Adrianoor Saputra Siti Raudhatul Jannah ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2021-06-30 2021-06-30 7 1 25 30 10.20527/twj.v7i1.91 The Effect of Organic Fertilizer and Liquid Complementary Fertilizer on The Seed Growing Medium from Topsoil http://twj.ulm.ac.id/index.php/twj/article/view/93 <p>In coal mine reclamation activities, topsoil is generally used as the top layer on the reclamation land surface and the primary material in the growing medium for reclamation plant seeds due to its abundant availability. Topsoil generally has a low fertility rate because the soil layers between horizons have been mixed. Improvement of topsoil quality can be performed by adding organic fertilizers. This study aimed to identify the effect of organic fertilizers, liquid complementary fertilizers (LCF), and their interactions on selected soil's chemical properties from the topsoil used as a seed growing medium. This study used a factorial completely randomized design (CRD) with two factors, consisting of organic fertilizer factors (guano phosphate, Subur Ijo, vermicompost) and LCF factors (IMO, liquid smoke, Vermiwash). The results showed that the independent treatment of organic fertilizers and LCF had a very significant effect on pH. The independent treatment of organic fertilizers had a very significant effect on organic C and Total K. Meanwhile, the interaction between the two treatments had a very significant effect on the Total N and Total P of the growing media. The addition of organic fertilizers and LCF can improve topsoil quality to be used as a medium for growing media.</p> Fazlul Wahyudi Bambang J.

Banjarbaru is one of the areas that started planting date palms in South Kalimantan. The community's knowledge of date pests still lacks. Therefore it becomes a problem for farmers. Before proper control is carried out, it is necessary to understand the types of pests first. Arthropod data on date palms at the Plantation and Livestock Service Office of South Kalimantan Province are not available. Hence, it is necessary to conduct inventory research and arthropod identification. This study aimed to determine the types of arthropods in date palms (<em>P. dactylifera</em> L.) in Banjarbaru. The method used was a survey method with purposive sampling carried out by collecting arthropods using swing nets, yellow sticky traps, and directly from four different locations. The field observations at four locations found 43 types of arthropods totaling 98 individuals. Twenty arthropods act as pests, 13 individuals as pollinators, and 10 individuals as predators. The arthropods were classified into ten orders and 27 families, with the largest number of individuals coming from the Lepidoptera order.</p> M.
