Abstract

This research was aimed to explore land function changes and contamination levels (BTEX and heavy metals) on the mangrove area. The results of BTEX parameters from soil sample and indentified benzene showed heavy metal contaminations on Plot A, B, C and D were16.30 ppm, 81.30 ppm, 56.90 ppm, and 93.50 ppm respectively, but it was not detected on Plot E. Toluene contaminations was 481 ppm, 824 ppm, 490 ppm, 896 ppm, and 93.50 ppm. It showed that Plot B and D were heavily contaminated. Based on EC values of water, it showed that contamination was heavy on Plot B (4.76 us/cm), Plot C (4.67 us/cm), Plot D (4.64 us/cm) and Plot E (4.66 us/cm). Based on water samples and detected benzene, it indicated an heavy contamination on Plot A (24.30 ppm), Plot B (8.13 ppm), Plot C (20.20 ppm), Plot D (8.13 ppm), Plot E (8.13 ppm), while toluene (460 ppm, 522 ppm, 509 ppm, 319 ppm, 522 ppm) contaminated slightly. Ethylbenzene and Xilene were not detected by gas chromatography. EC value of soil showed that intensive contamination occurred on Plot E (4.81 us/cm). It showed that intensive contamination took place on soil mainly by Pb contamination on Plot C, Plot D, and Plot E (5.98 mg/kg, 7.24 mg/kg, and 6.43 mg/kg). Meanwhile, Plot A and B were slightly contaminated only. The same levels occurred on Cu for all plots, except Plot A (6.22 mg/kg). Zn and Cr did not contaminate, while Ag and Cd were not detected. Water medium was not contaminated by Pb, Cd, Cr, and Zn. Furthermore, Ag and Cu were not detected.

Abstract

Tomatoes are important vegetable commodities and have high nutritional value. Until now, tomato productivity was still quite low at 16.09 - 18.63 tonnes/ha from 2015 to 2019 when compared to its potential which could reach 20-30 tonnes/ha. One of the ways to increase the productivity of tomato plants is to improve cultivation techniques, especially the use of suitable planting media and pest control by utilizing natural materials. The composition of the media that was suitable for tomato plants needs to be known to produce high-quality and high-yielding tomatoes. Bio-pesticide application using several plants with the appropriate dosage can be an alternative to reduce the use of chemicals. This study aimed to determine the composition of the plant media and the effectiveness of biopesticides to increase the production of tomato plants. The study used Completely Randomized Design (CRD) two factors, where the first factor is the composition of the growing media and the second factor is the dosage of vegetable biopesticides. The first factor is the composition of the growing media consisting of 4 levels, namely K0 (without bokashi), K1 (Soil: Bokashi = 11: 1 (W/W) per polybag, K2 (Soil: Bokashi = 5: 1 (W/W) per polybag), K3 (Soil: Bokashi = 3: 1 (W/W) per polybag. The second factor is the dosage of vegetable biopesticides consisting of 4 levels, namely A0 (control), A1 (20 ml per polybag), A2 (40 ml per polybag), A3 (60 ml per polybag). Each treatment consisted of 4 levels of treatment and was repeated 4 times so that there are 64 experimental units. The data were analyzed using analysis of variance, and the real effect then tested further using Least Significance Different at 5% level. The results showed that there was an interaction between the treatment of the composition of the planting medium and the biopesticide on the parameters of plant height, number of leaves, leaf area, number of fruits, fruit weight, and production. The composition of the soil growing media composition: bokashi (5:1) and 40 ml biopesticide (K2B2) produced the highest number of fruit which was 255.53 fruit, the largest fruit weight was 7.67 kg per plant and produce 10.22 tonnes/ha. The use of biopesticides is effectively applied to tomato plants so that it can reduce the number of plants affected by fusarium wilt disease. the ones with the highest number of healthy plants were in A2 treatment with a pesticide dose of 40 ml per plant at 81.25%.

Abstract

Sweet potato is a dual-purpose crop, which could produce both food and feed. The vine pruning prior to storage root harvesting was intended to increase the quantity and quality of fresh forage for animal feed. This study aims to evaluate whether periodic pruning can affect the storage root yield and its starch content. This experiment employed split-plot design with two factors and three replications. The first factor as main plot was vine pruning which consisted of four distinct pruning times (four times, three times, twice and once). The second factor as sub-plot was cultivars which consisted of six dual-purpose cultivars and two controls. The storage root yields, vine yields, starch yields and the reduction in storage root yields were observed. The results showed that the vine pruning decreased the storage root yields, with small increases the vine yields. The percentage of the reduction in storage root yields were 4-58%, while the decrease vine yields are relatively inconsistent. The starch yield of the cultivars with one pruning time were in the range of 2.34-6.67 ton ha-1. On the contrary, the three times pruning or more since 80 days after transplanted can reduce the starch yields for more than 50%. The slight increase in vines yield due to pruning was followed by the decrease in storage root yields and starch content of the sweet potato.
