Adding Ameliorant to the raised-bed soil as an effort to increase the utilization of support for the cultivation land. Chlorophyll or leaf green substances found in all green plants that carry out photosynthesis. Ameliorant applications can increase the chlorophyll content of plants to optimize plant growth. This study aims to look at the effect of giving several types of ameliorant to the content of chlorophyll (chlorophyll-a, chlorophyll-b and total chlorophyll) and the growth of corn planted on raised-bed soil. This research is an experiment in the laboratory and a greenhouse. This research was conducted using a <em>Completely Randomized Design</em> (CRD) Single Factor with the treatment tested was the type of ameliorant soil without treatment (control - K), soil + agricultural lime (dolomite - C), soil + palm empty fruit bunch ash (S), soil + rice husk ash (P) and soil + coal ash (B). All treatments were repeated 5 (five) replications so that there would be 25 units of the experiment. The results showed that the application of ameliorant in raised-bed soil using dolomite and oil palm empty fruit bunches ash with a dose of 5 tons ha<sup>-1</sup> affected the content of chlorophyll-a and total chlorophyll in the growth of corn planted in raised-bed soil materials.</p> Ronny Mulyawan, Akhmad Rizali Saidy, Rahmi Zulhidiani ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 http://twj.ulm.ac.id/index.php/twj/article/view/84 Thu, 30 Jul 2020 00:00:00 +0000 Effect of brine time on quality of wet-salted fish http://twj.ulm.ac.id/index.php/twj/article/view/83 <p>Stingrays or&nbsp;<em>Dasyatis sp. was</em>&nbsp;one kind of fishery commodities. This product was perishable, so it required careful handling through the handling process. Fish preservation was an alternative that can be applied. This study aimed to protect the fresh fish quality throughout the handling process before it was processed further. This research method used the wet-salting method. The principle of this method was to keep the product for a long time in brine for 0h (control/fresh fish), 1h, 2h, and 3h. The analysis achieve was TVB-N, TMA, TPC, total crude protein, and pH. The effect of time in brine on the <em>result&nbsp;showed significant variation with p-value &lt; 0.05. pH value was significantly correlated with TVB-N and total protein, while, TPC was significantly correlated with total crude protein. These conclusions, the fish</em>&nbsp;product for 1h in brine&nbsp;<em>was the best treatment</em>.</p> Zuliyan Agus Nur Muchlis Majid, Novianti Adi Rohmanna, Syifa’ Robbani ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 http://twj.ulm.ac.id/index.php/twj/article/view/83 Thu, 30 Jul 2020 00:00:00 +0000 Potential of Fungi Isolate as a Biological Control of White Root Disease (Rigidoporus sp.) on Rubber Plant http://twj.ulm.ac.id/index.php/twj/article/view/82 <p><em>Rigidoporus</em> <em>Sp</em>. is a white root fungus which is the main diseases problems on rubber plants in the wet and dry lands of South Kalimantan. An economically and ecologically beneficial control solution for this problem soil contagion was by using antagonistic fungi. This research was aimed to study the potential of <em>rhizosphere</em> and <em>endophytic</em> fungi in swampland, to control white root fungus on rubber plants. <em>&nbsp;</em>The research used exploratory method. <em>Rhizospheric</em> fungi were explored from swamp rubber plant roots at Pulau Damar village Hulu Sungai Utara District; <em>endophytic</em> fungi were isolated from leaves and jelutung swamps (<em>Dyera lowii</em>) which is rubber-like plants. The isolates found then were screened based on the percentage of inhibition using the dual culture method between pathogens and test isolates, also observed the interaction mechanism and viability test. The research in the laboratory was arranged using a Completely Randomized Design with one factor i.e. the type of antagonistic fungi. Five isolates which had the highest inhibitory power were isolates I13K4R, I7K3R, I1K2R, I6K2R, and I1E with successive inhibitions 95.00%, 83.00%, 76.50%, 62.50% and 53.00%. Thus, isolates have included potential antagonistic agents because they had the ability in space competition more than 50% and proven to be able to paralyze <em>Rigidoporus</em>. The viability test results showed that the isolate that had germination capability of more than 60% were respectively I13K4R 88.05%, I7K3R 87.33%, I1K2R 86.93%, I6K2R 72.85%, and I1E 74.78%.</p> Mariana Mariana, Kurnia Utami Dewi, Samharinto Samharinto, Ismed Setya Budi ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 http://twj.ulm.ac.id/index.php/twj/article/view/82 Thu, 30 Jul 2020 00:00:00 +0000 The Utilization of Rice Straw for Increase Orange Productivity and Reducing Environmental Pollution http://twj.ulm.ac.id/index.php/twj/article/view/78 <p>Siam Banjar oranges was one of the leading commodities in South Kalimantan with an area 2,594 ha, 113,-149 tons of production and 43.72 ha<sup>-1</sup> of productivity (Department of Agriculture South Kalimantan, 2006 in <a href="http://www.kalselprov.go.id/">www.kalselprov.go.id/</a>). The development of Siam Banjar oranges in South Kalimantan was overflow in Barito Kuala and Banjar District. The level of responsiveness plants for fertilization encourages farmers to apply high inorganic fertilizers. If it is applied continuously and without return organic matter into the soil, it will produce the reduced soil fertility in terms of chemical, physical, and biological soil. This research showed the effect of the use of straw in increasing the production of Siam Banjar oranges. First, they completely decomposed so that increasing soil fertility. Second, reduce environmental pollution because it did not leave residues as inorganic fertilizers. Third, prevent soil erosion so that nutrients needed by oranges for grow properly could be fulfilled optimally. So, oranges did not easily attacked by pests and diseases then provide abundant harvest. The results of the differences between two values ​​could be concluded that, the benefits of orange farming was produced with straw was greater than farming without straw. Revenue Cost Ratio (RCR) value of orange farming with straw was 3.56 and the Revenue Cost Ratio (RCR) value of orange farming without straw was 3.26. Based on the RCR value, orange farming with straw was more feasible than orange farming without a straw.</p> Rifiana Rifiana, Hamdani Hamdani ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 http://twj.ulm.ac.id/index.php/twj/article/view/78 Thu, 30 Jul 2020 00:00:00 +0000 Bacterial Contaminations of Broiler Chicken Meat Marketed in Banjarbaru http://twj.ulm.ac.id/index.php/twj/article/view/77 <p>This research aims to find out how high the level of bacterial contamination found in broiler chicken meat sold at the Bauntung Market, Banjarbaru. The method used in this research is the sampling method to determine the sample using the random sampling method used to determine the experimental test sample. This sampling was carried out for three days at 8:00 AM and 11:00 PM. The variables observed in this study were physical observation, the number of bacteria (TPC), and the type of bacteria. The data obtained were then performed a t-test (paired samples test) using a variety of SPSS (Statistical Product and Service Solution) program analysis 18. Laboratory analysis was carried out in the Microbiology Laboratory of the Faculty of Agriculture, Lambung Mangkurat University. The results obtained indicate that there are significant differences in Sig. (2-tailed) (&lt;0.05) between the collection times of the number of bacteria, so it can be concluded that the average level of bacterial contamination at the time of collection at 07.00 am lower than at 10:00 noon. Which is 2.13 x 109 cfu / g and 5.81 x 109 cfu / g. The whole sample taken at 07.00 am did not exceed the threshold, while taken at 10:00 noon had exceeded the threshold required by SNI. Bacterial contaminants that grow on EMBA and SSA media include&nbsp;<em>Escherichia coli, Klebsiella sp., Citrobacter, Shigella sp., Salmonella sp.,&nbsp;</em>and<em>&nbsp;Providencia.</em></p> Herliani Herliani, Muhammad Ilmi Hidayat ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 http://twj.ulm.ac.id/index.php/twj/article/view/77 Thu, 30 Jul 2020 00:00:00 +0000
