Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh interaksi jenis gulma dan konsentrasi ekstrak alang-alang sehingga dapat diketahui konsentrasi optimum yang dapat menghambat pertumbuhan setiap jenis gulma. Metode yang digunakan adalah metode uji hayati (bioassay) perkecambahan, dengan menggunakan Rancangan Acak Lengkap (RAL) faktorial yang terdiri atas dua faktor. Faktor pertama adalah jenis gulma, terdiri tiga level : Amaranthus spinosus (G1), Bidens biternata (G2) dan Tridax procumbens (G3). Sedangkan faktor kedua adalah konsentrasi ekstrak alang-alang, terdiri lima level yaitu : tanpa ekstrak (K0), konsentrasi 25% (K1), konsentrasi 50% (K2), konsentrasi 75% (K3) dan konsentrasi 100% (K4). Hasil penelitian menunjukkan bahwa penggunaan ekstrak alang-alang dapat menekan persentase perkecambahan, laju perkecambahan dan panjang kecambah dari biji-biji gulma Amaranthus spinosus, Bidens biternata dan Tridax procumbens. Peningkatan konsentrasi ekstrak alang-alang menurunkan persentase perkecambahan, laju perkecambahan dan panjang kecambah dari ketiga biji gulma yang diuji. Tingkat sensitifitas biji gulma terhadap ekstrak akar dan rimpang alang-alang yang tertinggi adalah Tridax procumbens diikuti Bidens biternata dan Amaranthus spinosus. Alelopat akar dan rimpang alang-alang yang dibuat ekstraknya sangat berpotensi digunakan sebagai bioherbisida untuk mengendalikan perkecambahan biji-biji gulma.Kata kunci : alang-alang (Imperata cylindrica), bioherbisida, bioassay.

Abstract

This study was designed to evaluate the role of sliced and dropping models of neem leaves (Azadirachta indica) and environmental factors on zebrafish wound shrinkage. This study employed two treatment models: neem leaf slices and drops model. The treatment in the neem leaf slice model was the control group (fish was injured without neem leaf slices treatment, and G1-G3 of each fish was injured at 0.3 cm + 0.5, 1, and 2 g. Treatment in the neem leaf drop model was control group (fish was injured without neem leaves drops, and G1-G3 of each fish was injured at 0.3 cm + 1, 2, 4 drops. Findings suggest that there is a significant difference between the control group by treating G1, G2, and G3 on the shrinkage of zebrafish wound area both in the neem leaf slice and drop models, but G1 was not significantly different from G2 and G3, as well as G2 and G3 both in the neem leaf slice and drop model. Neem leaves contain nutrients that play a vital role in the formation of collagen and the formation of new capillaries to help speed up the wound healing process. The healing process involves the dynamic interaction of physiological factors.

Abstract

Straw mushroom (Volvariella volvacea L.) has high nutritional value and good prospects for development. The straw mushroom market is still wide, while the supply is still low, it becomes an opportunity to cultivate it. This study aims to determine the response of the growth, yield and economic value (R/C ratio) of straw mushroom by adding wood fungus rejects substrate with different percentage and type of nitrogen source stover using a stacking tray system. This study using a Factorial RCD with two factors. The first factor is the percentage of wood fungus rejects substrate: A0 (control), A1(10% woody rejects substrate), A2 (20% woody rejects substrate), A3 (30% woody rejects substrate) and A4 (40% woody rejects substrate). The second factor is type of nitrogen source stover: N1 (leucaena), N2 (arachis) and N3 (gliricidia). The statistical test used analysis of variance ANOVA and BNJ follow-up level of 5%. The results of this study showed that there was no interaction between the two factors that were tried, but separately the percentage of wood fungus rejects substrates and types of stover had a significant influence on the parameters of observation. Wood mushroom reject substrate 40% gave the best response to almost all parameters of observation. While lamtoro stover gives a better response compared to arachis and gliricidae. The results of farming analysis using. Leucena stover have the highest farming value Rp. 48.004.917,- in 11 planting periods.

Abstract

Sawi is a type of vegetable that is liked by many people with a high nutritional content. Of the various types of mustard greens, pakcoy is the type that is widely cultivated. Pakcoy is a plant that contains various nutrients in the form of calories, protein, fat, carbohydrates, fiber, Ca, P, Fe, as well as vitamins A, B, C and E. This study aims to test the combination of vermicompost and vermiwash on the growth and yield of pakcoy plants good and optimum. This study used a randomized block design consisting of 2 factors. The first factor consists of Factor I, which is the vermicompost dose consisting of three levels, namely V1 = 100 g/pot, V2 = 200 g/pot, V3 = 300 g/pot. The second factor is the Vermiwash concentration consisting of three levels, namely K1 = 100 ml/liter, K2 = 200 ml/liter, K3 = 300 ml/liter, plus one control treatment using inorganic fertilizers. Each treatment combination was repeated nine times and each replication used four plant samples. The results showed that the combination of vermicompost and vermiwash had a significant effect on the growth of plant height, number of leaves and leaf area. The variable results show that the 200 g vermicompost treatment and 200 ml/l vermiwash concentrations give the same good results as 300 g vermicompost and 300 ml / l vermiwash concentrations, but the 100 g vermicompost and 300 ml/l vermiwash treatments give high results. amounting to 68.50 g. That the application of vermicompost and vermiwash doses is still not able to provide nutrients like inorganic fertilizers.

Abstract

Lettuce is one type of vegetable that is used for its leaves or often referred to as leaf vegetables. Selda also has a high nutritional content. Production of red lettuce is also still not able to meet the demand. This study aims to determine the interaction between vermicompost residue and vermiwash application on the growth, yield and color pigmentation of red lettuce. This research was conducted at a plastic house on Jl. MT. Haryono, Dinoyo, Lowokwaru Malang District with an altitude of ± 550 meters above sea level, air temperature ranging from 20 oC - 35 oC, which was carried out from October 2020 - December 2020. The design used was a Factorial Randomized Block Design (RAK) with Control. Factor 1 residual dose of vermicompost with 3 levels, namely: V1 = 100 g/pot Vermicompost, V2 = 200 g/pot Vermicompost and V3 = 300 g/pot Vermicompost. Factor 2 Concentration of Vermiwash with 3 levels, namely: K1 = 200 ml/L Vermiwash, K2 = 400 ml/L Vermiwash and K3 = 600 ml/L Vermiwash. Each treatment was repeated 3 times with 4 samples and 1 treatment using AB Mix nutrition (control). From the research, it was found that the residual dose of vermicompost and the concentration of vermiwash had a significant effect on plant growth and yield, except for the variables of plant height, root fresh weight and root dry weight. In general, the best treatments were V2K3 (200 g/pot Vermicompost + 600 ml/L Vermiwash) and V3K1 (300 g/pot Vermicompost + 200 ml/L Vermiwash). In observing leaf color pigmentation, visual determination of leaf color showed differences between treatments and controls and between replicates. Differences that occur between treatments with controls and between replications can be caused by several things, including the nutritional content given and the lighting received.

Abstract

Shallots (Alium ascalonicum L) is one of the most widely cultivated vegetable crops in Indonesia. The yield of shallots is less than optimal because farmers pay less attention to soil fertility. Improvement of planting media on shallots, one of which is by giving goat manure bokashi. A group of beneficial bacteria that can be useful for plant growth processes and increase crop yields are PGPR (Plant Growth Promoting Rhizobacteria). These bacteria can be purified from bamboo roots through fermentation for three days. The bacteria in PGPR include Pseudomonas sp., Bacillus sp., Azobacter sp., and Azospirilum sp. Factorial Randomized Block Design (RAK) with control, which consists of two factors. The first factor is the dose of goat dung bokashi consisting of 3 levels, namely; K1 : 15 ton/ha, K2 : 20 ton/ha, K3 : 25 ton/ha. The second factor is the concentration of PGPR (Plant growth promoting rhizobacteria), consisting of 3 levels; P1 = 10 ml/liter, P2 = 20 ml/liter, P3 = 30 ml/liter. The results showed that in general the growth parameters of the treatment of bokashi dose of goat manure 25 tons/ha combined with PGPR concentration of 30 ml/liter on plant length and number of leaves and on the parameters of tuber weight yield of tons/ha the best treatment for bokashi dose of 20 tons goat manure. /ha combined with a PGPR concentration of 20 ml/liter.
