The study was conducted at three fishing locations in October 2019-January 2020 using the experimental fishing method. The operation of square folding traps was done by a total of 60 units. The types of bait used are golden snails, shrimp paste, and trash fish. Fish catches were recorded in number, type, length, and weight, and analyzed using one-way anova test and kruskal wallis test. The composition of the square folding traps catches consists of six species. Marble goby (<em>Oxyeleotris marmorata</em>) is the most dominant catch (60%). The highest catch rate was obtained from box folding traps which were given golden snail bait at 173.50 g/trip, then trash fish bait at 76.88 g/trip and shrimp paste feed at 59.22 g/trip. The highest trap rate is golden snail bait of 12.33%. The bait treatment gives a real difference to the amount and weight of the catch, the golden snail bait gives the highest total number and weight of the catch compared to other baits.</p> Eko Setyo Budi ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2020-12-07 2020-12-07 6 2 30 37 10.20527/twj.v6i2.86 Application of Several Types of Rhizome Powder in Controlling Sitophilus Oryzae L. Pests in Local Siam Mutiara Rice http://twj.ulm.ac.id/index.php/twj/article/view/88 <p>Rice is the staple food of the Indonesian population. Siam Mutiara is the preferred local variety of rice in South Kalimantan. Sufficient rice availability must be supported by a rice surplus as food reserves.The main problem with rice storage is the emergence of<em> Sitophilus oryzae</em> L. Therefore it is necessary to control the pest. Non-toxic botanical pesticides can be applied to control <em>S. oryzae</em>. This study aimed to determine the effect of the application of several types of rhizome flour on the mortality rate of <em>S. oryzae</em>, population development of <em>S. oryzae</em>, and weight of Siam Mutiara rice to obtain the most effective rhizome flour. The research was conducted in March 2020 - August 2020 at the Agroecotechnology Production Laboratory, Faculty of Agriculture, Lambung Mangkurat University. The one-factor Completely Randomized Design method (CRD) was used by treating z<sub>0</sub> (control/without rhizome powder), z<sub>1</sub> (red galangal rhizome powder), z<sub>2</sub> (kencur rhizome powder), z<sub>3</sub> (red ginger rhizome powder), and z<sub>4</sub> (rhizome powder combination). The treatment was repeated 4 times so that there were 20 experimental units. The results showed that the application of red galanus rhizome powder, sling rhizome powder, red ginger rhizome powder, and rhizome powder combination was able to control the population development of <em>S. oryzae</em> and weight damage of Siam Mutiara rice due to <em>S. oryzae</em> pests. The rhizome powder that was most effective in controlling <em>S. oryzae</em> was z<sub>1</sub> (red galangal rhizome powder) with a mortality percentage of 32.50%, population of 7 individuals, and rice weight of 99.96%; z<sub>2</sub> (kencur rhizome powder) with a mortality percentage of 65%, population of 3 individuals, and rice weight of 99.97%; z<sub>3</sub> (red ginger rhizome powder) with a mortality percentage of 62.50, population of 4 individuals, and rice weight of 99.96%; and z<sub>4</sub> (rhizome powder combination) with a mortality percentage of 47.50%, population of 5 individuals, and rice weight of 99.95%.</p> Riza Adrianoor Saputra Noor Khamidah ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2020-12-03 2020-12-03 6 2 38 43 10.20527/twj.v6i2.88 Marketing Analysis of Catch Resuts Snakehead Fish Central Muning Village, Daha Selatan Sub-District, Hulu Sungai Selatan Regency of South Kalimantan http://twj.ulm.ac.id/index.php/twj/article/view/81 <p>This study aims to: 1).

Based on the puddle level and duration, tidal swamp land has three typologies, namely shallow tidal swamp, middle tidal swamp, and deep tidal swamp. The wetlands in Ampukung village are classified in tidal swamps. &nbsp;Most of the tidal swamps have been utilized for agricultural activities, especially rice. Till now, rice farming in the tidal swamps of Ampukung village has not experienced any significant problems. In 2016, the rice harvest in Ampukung village exceeded the target of South Kalimantan. This success is considered to be increased by planting twice a year. However, some issues need to be addressed regarding the characteristics of the land in Ampukung village. Soil fertility, especially soil acidity, is one of the limiting factors in the utilization of tidal swamp land. Therefore, it is necessary to identify the acidity of the soil in the tidal swamp of Ampukung village. The acidity data is basic information to determine the condition of soil fertility to achieve the target of planting rice twice a year. This information will be presented in the form of a map to assist users in interpreting the research data. This study found that the soil pH in the tidal swamp lands of Ampukung Village, which was planted with rice, was highly acidic and homogeneously distributed.</p> Noor Khamidah Riza Adrianoor Saputra ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2020-12-03 2020-12-03 6 2 50 55 10.20527/twj.v6i2.87 Growth Response, Production and Analysis of Revenue of Hiyung Cayenne Pepper (Capsicum frustescens L) with Dosage Application of Liquid Bokashi Fertilizar (LBF) from Cattle Wate and Rice Straw http://twj.ulm.ac.id/index.php/twj/article/view/89 <p>This study aimed to (1) analyze the nutrient content of liquid bokashi fertilizer (LBF) derived from cattle waste and rice straw, (2) analyze the effect of liquid bokashi fertilizer dose on plant height, age of first flowering, and the number of fruits in the first harvest, the weight of the first fruit, and the weight of fresh fruit biomass. Analyzing revenue (income versus cost) and the feasibility of planting the Hiyung cayenne pepper by applying LBF at various dosage levels. The method used in this study was a Single Complete Randomized Design (CRD) with data analysis using ANOVA with further testing of Real Differences (LSD). B0 was control (without bokashi). B1 consisted of 125 ml of LBF and water to dilute the solution up to 500 ml. B2 consisted of 250 ml of LBF and water to dilute the solution up to 500 ml. B3 consisted of 375 ml of LBF and 125 ml of water. B4 consisted of 500 ml of LBF. The results showed that the highest growth response (69 cm) occurred with the addition of 125 ml of LBF, while the lowest growth occurred in the control (B0). In the first age, the most optimal flowering occurs in the B2 of 60.00 dap, and lowest in the control (B0) of 50.00 dap. The highest number of fruits was obtained from B2 of 170.00 g, and the lowest was in B0 (control) of 94.00 g. The average weight of the first fruit was found in B2 of 285.00 g, and the lowest in B0 (control) of 126.00 g. The highest weight of plant biomass was found in B2 of 405.00 g, and the lowest was in B0 (control) of 177.75 g. The highest revenue analysis and business feasibility were found in B2, namely Rp. 17.065,00 and the ratio of 4,96. The lowest revenue occurred in Control, which was Rp 5.318,75, with a TR/TC value of 2,28. Based on the revenue analysis, B2 treatment produced the highest revenue and was the most feasible to be applied compared to other treatments.</p> Mahdiati Mahdiati Danang Biyatmoko ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2020-12-07 2020-12-07 6 2 55 59 10.20527/twj.v6i2.89
