Abstract

The demand for mustard plants has not met the demands of the community because its productivity is still relatively low. Agricultural land, especially in urban areas is getting narrower, less labor in agriculture, and reduced nutrient availability in the soil are the main reasons for low productivity. In addition, the use of chemical fertilizers by farmers and the high rainfall in Sorong City are also the cause of the low production so that the community's needs are not fulfilled. Therefore, research was conducted with the aim of increasing the yield and quality of mustard plants by using a floating raft hydroponic cultivation system by utilizing stale rice into liquid organic fertilizer. This study used a randomized block design (RAK) with 4 treatments each repeated 3 times. The treatment is by giving fermented stale rice, 0 gr (control), 100 gr, 150 gr, and 200 gr. The difference in the concentration of liquid organic fertilizer of stale rice has an effect on plant growth, namely the increase in plant height, number of leaves, root length, leaf area, and wet weight by the floating raft hydroponic technique. Liquid organic fertilizer treated with 200 g of fermented stale rice gave the best effect on the growth of mustard plants using floating raft hydroponics.

Abstract

This study aimed was to find an integrated technology to obtain optimum spacing and effective weed control on various varieties based on the peanut yield approach. The design used was a Completely Randomized Block Design arranged in a factorial manner, consisting of 3 factors: Factor 1, plant spacing of 30 x 10 cm, and 40 x 10 cm. The second factor was the type of weed control, which was weeded twice at 21 and 42 days after planting, and the use of the herbicide glyphosate 1.44 kg b.a per hectare. The third factor is the variety of peanuts, namely the Jepara, Kelinci, and Panter varieties. All treatments were repeated 3 times. The data obtained were analyzed by analysis of variance and continued with Duncan's Multiple Distance Test with a significant level of 5%. The results showed that the independent spacing treatment significantly affected all observed parameters. The weed control significantly affected all parameters except seed weight per plot, and varieties treatment significantly affected all parameters except the dry weight of the stover. Interaction between planting distance and weeding type had a significant effect on all observation parameters except the dry weight of the stover.

Abstract

The level of heavy metal contamination of mercury (Hg) and lead (Pb) in the aquatic ecosystem of the Waiting Pampang Reservoir, Makassar City, is known by determining the concentration of these heavy metals in water and biota (tilapia). Tilapia is a catch that is relatively abundant in the Waiting Pampang Reservoir. This study aimed to determine water quality and levels of Hg and Pb contamination in water and tilapia caught from the Waiting Pampang Reservoir. Water quality is determined by measuring 1) the degree of acidity (pH), 2) Dissolved oxygen (DO), 3) Biological oxygen demand (BOD), and 4) Chemical oxygen demand (COD). The results showed that the BOD and COD values had passed the threshold so that the waters of the Waiting Pampang Reservoir were contaminated with organic matter. However, it has not been contaminated with Hg and Pb (<0.001 mg/kg) heavy metals. Tilapia caught from the Waiting Pampang Reservoir contained heavy metal Pb, but the concentration was far below the permissible value. However, the consumption of tilapia from the Waiting Pampang Reservoir must still be watched out for because heavy metals are accumulative.

Abstract

This study aimed to analyze the performance of tiger prawn Penaeus monodonseed which were fed taurine-enriched Artemia. The study was conducted by using a completely randomized design.The treatment in this research was taurine enrichment dosage of Artemiathat consist of 4 levels: 0 gL-1 (DPT-0), 0.5 gL-1 (DPT-0.5), 1.0 gL-1 (DPT-1.0) and 1.5 gL-1 (DPT-1.5) in triplicate. Larvae stocked at a density of 50 individu.L-1 were fed Artemianauplii from Mysis-3 to PL-12 stages. Measurement and analysis data to compare the effects of these treatments were tested by analysis of variance (ANOVA) followed by Duncan's multiple range test at a significance level of 0.05. The results showed that the taurine content of Artemia increased significantly and linearly with the enrichment dose of taurine. Furthermore, the specific growth rate and visual quality of larvae increased significantly by feeding taurine-enriched Artemiaof 1.0 gL-1, but increasing the taurine enrichment dose to 1.5 gL-1 in the Artemia was not followed by an increase in these parameters. The vitality and resistance of larvae increased significantly and linearly with increasing in taurine enrichment dose, whereas the survival rate for larvae only increased significantly with 0.5 gL-1 taurine-enriched Artemia. Based on these results, the best post-larval performance of tiger prawns was obtained by feedingArtemia enriched with taurine 1.0–1.5 gL-1.

Abstract

This study aimed to determine the effect of urea added with organic matter in a high C/N (50-70) or low C/N (10-20) ratio on the hydraulic conductivity and electrical conductivity of Ultisol soil. The research was arranged in a Split Plot Design. The main plot is organic matter, ie, without organic matter, calopogonium leaves, and rice straw 1,275 x 10-8 kg/ha, equivalent to 15.3 g/pipe. Sub-plots were urea doses consisting of 0, 100, and 300 kg/ha, equivalent to 0 g/pipe, 0.0425 g/pipe, and 0.0825 g/pipe, respectively, applied to Ultisol soil. Sample of Ultisol soil was taken at a depth of 0 -120 m which were air-dried, then sifted, mixed with TSP, organic matter, and urea according to treatment. The sample was put in a PVC tube (pipe) with the bottom covered with fine gauze to hold the soil but still allow percolation. . Incubation was carried out for two weeks. Observations were made after the incubation period, including hydraulic conductivity and electrical conductivity. The application of organic matter and urea at a dose of 300 kg/ha can increase the electrical conductivity of the soil. Adding the main organic matter with a high C/N ratio (rice straw) increases the hydraulic conductivity. Electrical conductivity (EC) is a good indicator in explaining the dispersive effect of urea and the effect of flocculation of organic matter. High electrical conductivity always results in high hydraulic conductivity in Ultisol soils.
