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.

ABSTRAK Kelapa sawit merupakan tanaman perkebunan yang memegang peranan penting dalam industri pangan. Luas perkebunan kelapa sawit di Indonesia pada tahun 2014 mencapai 10 juta Ha. Pertumbuhan yang pesat diikuti dengan produksi crude palm oil (CPO) dan palm karnel oil (PKO) yang juga meningkat, sekaligus produk sampingan berupa limbah. Salah satu limbah pabrik kelapa sawit yang jumlahnya besar adalah tandan kosong kelapa sawit (TKKS). Tandan kosong kelapa sawit merupakan limbah organik yang berpotensi dimanfaatkan dibidang pertanian. Akan tetapi, TKKS memiliki nilai C/N yang cukup tinggi, akibatnya sukar dan lama untuk terdekomposisi. Salah satu cara pemanfaatan TKKS adalah dengan dilakukan pengomposan dengan pengkayaan urea. Diharapkan dengan perlakuan tersebut TKKS akan cepat terdekomposisi dan dapat segera dimanfaatkan oleh tanaman. Penelitian ini bertujuan untuk (1) mengetahui pengaruh pemberian urea terhadap pengomposan TKKS dan (2) mengetahui pengaruh peningkatan dosis urea terhadap kualitas kompos TKKS. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) faktor tunggal dengan 5 perlakuan, yaitu U1 (urea 0 g setara dengan nilai C/N=), U2 (urea 30,9 g setara dengan nilai C/N=), U3 (urea 79,3 g setara dengan nilai C/N=), U4 (urea 176,1 g setara dengan nilai C/N=) dan U5 (urea 466,3 g setara dengan C/N = ) dan 9 ulangan, sehingga diperoleh 45 satuan percobaan. Hasil penelitian menunjukan bahwa pemberian urea berpengaruh sangat nyata terhadap susut bobot, kadar air, nilai pH kompos, C-organik, N-total, P-tersedia, dan nilai C/N, selain itu pemberian urea mengakibatkan terjadi perubahan tekstur dan warna pada kompos TKKS. Pemberian dosis urea 466,3 g mampu meningkatkan kandungan N-total, serta menurunkan nilai C/N dan nilai pH kompos. Pemberian dosis urea 79,3 g atau setara dengan C/N = mampu meningkatkan kandungan P-tersedia dan kadar air, menurunkan susut bobot dan kandungan C-organik, serta menunjukan perubahan tekstur dan warna yang lebih baik.

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.

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.
