Depuration is an effort to reduce/eliminate contamination including microplastics, which one is using a water circulation system. This study aims to determine the effective depuration time to reduce the microplastic content in Asaphis detlorata This study used a quantitative approach with experimental research design with a completely randomized design. There are 450 shells used as an experimental animal where is the treatment consisted of four depuration times, namely 1;2;3; and 4 days with 3 repetitions of each treatment, while the control shells were without depuration. Analysis of variance (ANOVA) was used to see the effect of depuration treatment on the microplastic content. If the effect of the treatment was significantly different, then the post hoc test was continued to determine the differences between treatments. The results showed that Asaphis detlorata obtained from the mouth of the Lakatong river estuary were contaminated with microplastics ranging from 0.6 to 8.1 MPs/shellfish and an average of 3.96 MPs/shellfish. Depuration time significantly affected the microplastic content in shellfish depuration effectiveness. There is a tendency that the longer depuration time is decreased microplastic content in shellfish. The effective depuration time to reduce the microplastic content in Asaphis detlorata was 3 and 4 days. Further research is needed for a more effective depuration for cleaning microplastics in shellfish.

Plants that can be used as pesticides are Gadung tubers. Gadung tubers contain cyanide acid to kill armyworm pests because they contain dioscorin toxins which can cause nervous disorders. The purpose of this study was to determine the effect of Gadung tuber extract (Dioscorea hispida) on Caterpillar mortality (Spodoptera exigua) in Shallot plants. This type of research is experimental research. This study used a completely randomized design (CRD). The sample used was 5 caterpillars (Spodoptera exigua) in each polybag with 5 repetitions for each concentration of Gadung tuber extract, namely 0%, 0.5%, 1.0%, 1.5%, 2.0% and 2.5%, so the total Caterpillar used was 150 Caterpillars. Gadung tuber extraction was carried out by maceration method with methanol solvent. Data were analyzed using a one-way analysis of variance at the 95% significance level, followed by DMRT (Duncans Multiple Range Test). The results showed that the Gadung tuber extract had a significant effect on the mortality of caterpillars (Spodoptera exigua) because the F count was greater than the F table (45.40>2.62), and the DMRT test results showed that the optimal concentration of Gadung tuber extract was 2.5%. Therefore, it can be concluded that the extract of Gadung tuber (Dioscorea hispida) affects the mortality of Caterpillars (Spodoptera exigua) in Shallots (Allium cepa).

ABSTRACT: The use of plant species for the phytoremediation of soils contaminated with herbicides is an alternative that has been emphasized to minimize the effects of the persistence of agrochemicals in the environment. The objective of this study was to evaluate the tolerance potential of winter species in soils contaminated with sulfentrazone and fomesafen. The experiment was in a completely randomized design with four replications. Doses of fomesafen (0.0, 0.125, 0.250, and 0.5 kg ha-1) and sulfentrazone (0.0, 0.3, 0.6 and 1.2 kg ha-1) were applied during the pre-emergence of phytoremediate species (black oat, vetch, birdsfood trefoil, radish and lupin). Forty five days after the emergence of the species, the phytotoxicity (%), leaf area (cm2), stalk and/or stem diameter (mm), height (cm) and dry matter (g) variables of the plants were evaluated. Data were submitted to analysis of variance by F test; when significant, linear or non linear regressions were applied to evaluate the effect of herbicide doses on the studied species. Birdsfood trefoil was the less tolerant species to fomesafen and sulfentrazone. Black oat was less affected by the application of fomesafen doses, but it was highly susceptible to sulfentrazone. Radish presented tolerance only up to the fomesafen dose of 0.25 kg ha-1; as for sulfentrazone, the species showed tolerance. The most tolerant species to fomesafen and sulfentrazone, regardless of the dose, was the lupine, which is a possible alternative for the phytoremediation of soils contaminated with these herbicides.

Red spinach (Amaranthus gangeticus) is one of the most popular vegetables because of its high nutritional value and easy cultivation. Efforts to increase the production of red spinach are to fertilize to meet the needs of both macro and micronutrients. This study aimed to determine the effect of ZA fertilizer dose on the growth and yield of red spinach. The environmental design used was a non-factorial, completely randomized design with four replications. The factors tested were the dose of ZA fertilizer which consisted of 6 levels, namely: without ZA fertilizer (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr/polybag (D5). The data obtained were analyzed using analysis of variance, and if the results were significantly different, the BNT test was continued at a 5% level. The growth and yield of red spinach showed significant differences due to the ZA fertilizer dose treatment. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest plant height, the number of leaves, and leaf area of red spinach at 14, 21, and 28 days after planting. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest wet and dry weight plants of 49.15 and 4.38 grams, respectively. The ZA 1.2 gr/polybag dose is the ideal dose to increase the productivity of red spinach.Bayam merah (Amaranthus gangeticus) termasuk sayuran penting yang disukai masyarakat karena bernilai gizi tinggi dan mudah pembudidayaannya.

EFFECT OF REPLACEMENT OF CORN WITH SORGUM Cv. KAWALI IN PELLET RANSUM ON LOCAL RABBIT PERFORM. The purpose of this study was to determine the effect of substitution corn with sorghum in rabbit rations on feed consumption, body weight gain, and ration conversion. The duration of the study was 28 days using 20 local rabbits. The statistical design used in this study was a completely randomized design, with 4 (four) treatment rations and 5 (five) replications. The four experimental rations, namely R0: 45% corn + 0% sorghum, R1: 30% corn + 15% sorghum, R2 15% corn + 30% sorghum, R3 0% corn + 45% sorghum. Variables were measured, viz: feed consumption, body weight gain and ration conversion. The results showed that the average of feed consumption, body weight gain, and feed conversion, were: 28.27–30.59 g /head /day, 15.76–21.55 g / head /day, and 1.42-1.80 g /head /day, respectively. Based on the analysis of variance, the treatments ration had no significant effect (P> 0.05) on consumption, but had a very significant effect (P <0.01) on body weight gain and feed conversion. The LSD test showed that all treatment rations using sorghum (R1, R2, and R3) gave results of body weight gain which were very significantly different (P <0.01) and higher than R0. Whereas, on ration conversion, treatments R1, R2, and R3 give very different results (P <0.01) lower than R0. It is concluded that the substitution of corn with sorghum at the level of 45% in the ration gives the highest results for body weight gain and conversion of rations for rabbits. Keywords: corn, sorghum, ration, performance, local rabbit
