Crocidolomia binotalis Zell is an important pest in Brassicaceae vegetable crops. Vegetable insecticide is one potential alternative to controlling the pest. This study aims to determine the application time of noni fruit extract and to determine the effective concentration of noni fruit extract as a vegetable insecticide in controlling C. binotalis larva on cabbage plants in the field. this study used a Completely Randomized Design (RAL) consisting of two treatment factors and four replications. The first factor is the concentration of extract (5 ppm, 10 ppm, 15 ppm and 20 ppm) and the second factor is the time of application of vegetable pesticide before the pest is invested (W1) and after the pest is invested (W2). So there are 32 units of experiments and 4 units of experiments added as control. The results showed, noni fruit extract had no significant effect on mortality of C. binotalis larvae. The highest mortality rate is at 100% K2 (10ppm) concentration at the time of application before the pest is invested (W1). The interaction had significant effect on the wet weight of the plant canopy but had no significant effect on the mortality of the pest, the intensity of the attack, the percentage of pupa formed, and the present percentage of imago.

Plutella xylostella is an important pest of Brassicaceae vegetable crops. Frequent use of insecticides containing single active ingredients can cause resistance in P. xylostella. This work was done to evaluate the synergism between Piper aduncum fruit extract and three microorganism-derived insecticides, i.e. abamectin, chlorfenapyr, and spinetoram, against P. xylostella from Pacet District, Cianjur Regency. Results of leaf-residue feeding bioassays with 48-h feeding treatment showed that LC95 of abamectin, chlorfenapyr, and spinetoram at 96 h after treatment (HAT) was about 5.8, 7.0, and 1.9-fold higher than their respective field rates. Thus, based on leaf-feeding assays P. xylostella larvae from Pacet-Cianjur were not susceptible to abamectin and chlorfenapyr, but were still fairly susceptible to spinetoram. LC95 of P. aduncum extract at 96 HAT was 0.68% (w/v). Based on combination index at the LC95 level - 96 HAT, mixtures of P. aduncum extract with all three test insecticides were synergistic. Thus, P. aduncum extract is potential to be used as an alternative ingredient to increase the effectiveness of the three test insecticides against P. xylostella.Keywords: Botanical insecticides, cabbage pest, insecticide mixtures, microorganism-derived insecticides, synergism.

Surya DH, Mariyah Y, Tahono. 2009. The influence of noni fruit (Morinda citrifolia) extract toward the level of SGOT and SGPT enzymes on white mice induced by carbon tetrachloride. Biofarmasi 7: 87-93. Noni fruit (Morinda citrifolia L.) is a wellknown crop in the society. It is determined for its contents including proxeronine and some antioxidants, i.e. ascorbic acid and beta-carotene that function to maintain and improve cell function. This research used hepatic cells considering the vital function of the hepatic organ in the body. The purpose of this research was to determine the effect of noni fruit extract to reduce hepatic cells damage induced by CCl4. This research was included into laboratory experimental research and used a completely randomized design. The samples consisted of 25 male white mice (Mus musculus) type Swiss Webster with the age between 3-4 months and the weight between 20-30 grams, and divided into 5 groups. The first group was the CCl4 control group, in which white mice were given toxic dosage of CCl4 11 mg/20 g BW without noni fruit extract treatment. The second group consisted of white mice given by noni fruit extract in dosage of 0.56 g/20 g BW for 8 days, and in 8th day they were given by a toxic dosage of CCl4 11 mg/20 g BW. The third group consisted of white mice given by noni fruit extract in dosage of 1.12 g/20 g BW for 8 days, and in 8th day they were given by a toxic dosage of CCl4 11 mg/20 g BW. The fourth group consisted of white mice given by noni fruit extract in dosage of 2.24 g/20 g BW for 8 days and in 8th day they were given by a toxic dosage of CCl4 11 mg/20 g BW. The fifth group consisted of white mice given only water and daily food for 8 days. Blood samples from all white mice were taken after 24 hours to determine the level of SGOT and SGPT enzymes. The results were analyzed by using One-Way Anova statistical test, which continued with Post Hoc Test and Tukey Test. The result of research showed that noni fruit extract in dosage of 0.56, 1.12, and 2.24 g/20 g BW given per oral could reduce SGOT level in 214.48±48.804 U/I, 151.16±22.811 U/I, and 169.62±44.891 U/l, respectively, compared with a positive control of CCl4 that was 296.62±59.254 U/I. Meanwhile, SGPT level became 55.42±4.292, 54.34±6.896, 58.58±8.210 U/I, compared with a positive control of CCl4 that was 83.96±2.931 U/I.

Tomato was classified as a climacteric fruit with a fast ripening period andthen followed by the increase of fruit softening. The inhibition of fruit softening was needed to maintain the quality and shelf life of the fruit. One of the way to inhibit the tomatoes softening was calcium application. However, the best concentration and timing of calcium application for tomato was still limited. The aimed of research was to determine the best combination of concentration and time of application of calcium chloride (CaCl2) to the physicochemical of tomato. Experiment was arranged in factorial completely randomized design (CRD) with two factors and three replications. First factor was concentration of CaCl2 which consisted of 5 levels (0 M; 0.3 M; 0.6 M; 0.9 M; 1.2 M), while the second factor was application time of CaCl2 (pre- and post-harvesting). The results showed that there was no interaction between concentration and application time of CaCl2 to the physicochemical of tomatoes. Treatment of CaCl2 1.2 M could increased fruit calcium content, inhibited weight loss and fruit softness, increased total titrated acid content, and inhibited the degradation of vitamin C. The application time of CaCl2 in pre- and post-harvest was not significantly different in term of physicochemical properties. Keywords: fruit softness, quality, weight loss, shelf life, vitamin C

Indian mustard plants are the main vegetable crops consumed by urban communities. The need for this vegetable increases along with the increase in culinary tourism in each region and the government's appeal on sustainable food home. One effort made to meet the needs of vegetable mustard in urban areas can be cultivated using polybags. The main problem of vegetable cultivation on polybags is the availability of soil media. To overcome the limitations of soil media it is attempted to substitute it with organic litter enriched with MOL (local microorganisms). The purpose of research is to find the right combination of planting media for mustard plants. The results showed that the composition of K7 = soil: compost: litter of hay: litter of maize (2: 1: 1: 1) best on plant length, number of leaves, length of root leaves and number of roots while the wet weight of mustard plant (g) K7 = soil: compost: litter of maize: litter of corn (2: 1: 1: 1) and K8 = soil: compost: litter of maize: litter of maize: cocopeat (2: 1: 1: 1: 1) or soil: compost + urea. Increased weights of wet mustard by 63% compared to soil media and 20% compared to soil composition: compost + urea. Organic straw in the form of straw: litter of corn stalk: cocopeat enriched with MOL are able to become ready-made planting media on the cultivation of indian mustard plants in polybags.
