Mining Law

Open mining activities have caused soil damage, water pollution, air pollution, and damage to vegetation. Limestone post mining is a critical area that must be rehabilitated to be productive again. This problems can be fixed by doing land reclamation activities which mandated in the Mining Law Number 4, 2009. The success of land reclamation is largely determined by the choice of plant species and the provision of appropriate soil enhancers (ameliorant). This study was aimed to analyze the growth response of sengon plants on giving ameliorant in mixed limestone post mining soil. This study was designed in completely randomized design for 7 treatments and 3 replications used combination of ameliorant: P0 (without ameliorant); P1 (AH 4 kg ha-1); P2 (BFA 350 kg ha-1); P3 (FMA 500 spores plant-1); P4 (the combination of AH and FMA); P5 (the combination of BFA and FMA); and P6 (the combination of AH, BFA, and FMA). Data were processed by analysis of variance at the 0,05 significance level followed by the Least Significant Difference test. The results showed that the best growth response of sengon on giving ameliorant in mixed limestone post mining soil was P1 treatment (humic acid material) which significantly increased root length, root volume, root fresh weight, shoot fresh weight, root dry weight, and shoot dry weight in sengon plants. The addition of ameliorant can be recommended to improve the quality of revegetation plants

Irmawati, Solichatun, Anggarwulan E. 2007. The growth and reserpine content of callus culture of Rauvolfia verticillata on the variation of sucrose concentration in MS medium. Biofarmasi 5: 38-46. The aim of this research was to study the effect of the variation of sucrose concentration on the growth and reserpine content on callus culture of Rauvolfia verticillata (Lour.) Baillon. The research was conducted with callus culture method consisted of two stages. The first stage was callus initiation to induce callus from leaf explant of R. verticillata, and the second stage was the reserpine production on treatment medium. This research used a Completely Randomized Design (CRD) by one factor, i.e. the variation of sucrose concentration. The sucrose concentration consisted of five levels, i.e. 0 g/L, 10 g/L, 20 g/L, 30 g/L and 40 g/L, each concentration in five replicates. The collected data consisted of qualitative and quantitative data. The qualitative data, callus morphology, was presented descriptively. The quantitative data, included fresh weight callus, dry weight callus and reserpine content, were analyzed by using ANOVA and followed by DMRT at 5% significance level. The result of research showed that the variation of sucrose concentration influenced fresh weight callus, dry weight callus and reserpine content. The increasing of sucrose concentration tended to raise callus growth, which could be seen from the fresh and dry weight callus. The highest fresh weight callus was found in medium with sucrose concentration of 20 g/L, while the highest dry weight callus was found in medium with sucrose concentration of 40 g/L. The increasing of sucrose concentration until 30 g/L raised reserpine content, but the sucrose concentration over 30 g/L decreased the reserpine content.

Resistance induction through the use of chemical inducers often results in physiological costs to the plant. In this study, induced resistance in cotton plants was evaluated with regard to physiological costs in a cultivar susceptible to Colletotrichum gossypii var. cephalosporioides (CNPA GO 2002 - 7997). Plants were cultivated in substrates with two levels of nitrogen and received two applications of acibenzolar-S-methyl (ASM), jasmonic acid (JA) and Agro-Mos® (AM) disease resistance inducers. Plant height (H), internodal length (IL), shoot fresh weight (SFW), root fresh weight (RFW), shoot dry weight (SDW) and root dry weight (RDW) were evaluated. The activity of the phenylalanine ammonia lyase (PAL) and peroxidase (POX) was also determined. The plants treated with ASM presented high physiological costs with an accentuated reduction in H, SFW and SDW, whereas those treated with JA exhibited a significant increase in SDW, and did not significantly differ from H and IL. In the potting mix supplemented with nitrogen, all inducers differed from the control treatment regarding to internodal length, whereas only ASM and AM presented a significant difference between one another in the potting mix without the addition of nitrogen. Significant correlations (P=0.05) were found for most of the variables analyzed, with greater correlations observed between SFW and SDW (0.94); IL and H (0.74); SFW and H (0.70); and SDW and H (0.70). ASM induced the least amount of PAL activity, significantly differing from the remaining treatments. Greater POX activity was observed in ASM, which significantly differed from the control. AM and JA, however, presented lower activity than the control with regard to these enzymes, and it was not possible to confirm induction resistance in these two treatments.

This study aims to determine the growth response of the vegetative stadia of three soybean varieties which are widely used in East Java on acid soils that have been given biological fertilizers from various Trichoderma isolates. The experiment was arranged factorially using a completely randomized design. The first factor was the variety consisting of Detam 3, Detam 4, Gema, Dering 1, and Burangrang. The second factor was Trichoderma isolates formulated as bio fertilizers, consisting of Tc-Jjr-02, Tc-Pjn-01, and Tc-Jro-01. Overall this experiment has 60 experimental units. Data were analyzed by variance analysis (ANOVA) followed by an honest significant difference test at the level of 5%. The results showed that there was no interaction between soybean varieties and Trichoderma isolates formulated in bio fertilizer. Soybean varieties significantly affected plant height, wet weight, and dry weight of roots and stover at 21 days after planting. The Burangrang variety shows the best growing ability in acid soils. There was no interaction between soybean varieties and Trichoderma bio fertilizers. Trichoderma isolate Tc-Jjr-02 increased the wet weight and dry weight of the roots and roots by 48.2 and 54.5%, respectively, and 38.9 and 48.2% compared to without Trichoderma. Trichoderma application maintains soil acidity between pH 4.50-4.67.

Chrysanthemum plants besides being used as ornamental plants and cut flowers can also be useful in the world of health, namely as herbal tea. The parts of the plants used are leaves, flowers or both at once. The addition of different light colors in chrysanthemum plants is expected to improve the quality of chrysanthemum tea by increasing antioxidant compounds in chrysanthemum leaves. This study aims to determine the effect of the addition of different light colors on the growth and content of antioxidant compounds in the leaves of these plants. This research using Complete Randomized Design (CRD) consisting of 4levels with 5 replications. The treatments given were 4 different colors namely white (W1), red (W2), yellow (W3), blue (W4). Observation data were analyzed using analysis of variance (ANOVA), if there was a significant difference, then Duncan's Multiple Distance Test was conducted at 95% confidence level. The addition of different light colors had a very significant effect on total fresh weight, leaf fresh weight, fresh weight of stover and antioxidant activity then significantly affected plant height, total dry weight, leaf dry weight and dry weight of stover. But the number of leaves shows an unreal effect. The results showed that the addition of blue and yellow light colors had the highest effect on the content of antioxidant compounds.

Abstract Porang (Amorphophallus muelleri Blume) is usually cultivated on the field under the tree as natural shading. Porang can also be grown on a pot containing limited amount of growth media. The present research work was carried to evaluate the minimum amount of growth media required for optimum growth and corm yield. The study used bulbils (10 g/bulbil and 20 g/bulbil) and corm (+ 15 g/corm) sown on growth media of 2.5 kg, 5.0 kg and 7.5 kg/pot as treatments. Each treatment was arranged in completely randomized design and was replicated 3 times. Plant height, plant diameter, shoot dry weight, diameter and thickness of corm and fresh weight of corm were measured to evaluate the influence of the treatments on growth and corm yield of porang. The plant growth of porang measured as plant height, plant diameter, shoot dry weight was improved when the planting materials were planted on bigger size of growth media. Bigger size of bulbil caused better growth of porang on each growth medium. The effect of plant materials and the size of growth media on porang growth was in parallel to its effect on corm yield measured as corm diameter, corm thickness and fresh weight of corm. The result of the present study suggests to use bigger bulbil and bigger size of growth media when planted on polyethylene bag. Corm as planting material was better than bulbil because less size of corm produced similar plant growth and corm yield compared to bigger size of bulbil. Therefore, the use of corm as planting material is more favorable to bulbil.

An in-vitro test was conducted at the laboratory of the Department of Genetics and Plant Breeding, Hajee Mohammad Danesh Science and University (HSTU), Dinajpur, Bangladesh to screen out the tomato genotypes were screened for salt tolerance during germination. The test was conducted in the Completely Randomized Design (CRD) utilizing three replications. Ten tomato genotypes specifically BARI Tomato-2, BARI Tomato-3, BARI Tomato-5, BARI Tomato-11, BARI Tomato-14, BARI Tomato-16, Mintoo, Unnoyon, Mintoo Super and Sawsan were germinated on sand bed watered with five levels of salinity treatment i.e. 0, 4,8,12 and 16 dSm-1. The test was laid out in completely randomized design (CRD) with three replications. The days to 50% germination was maximum in Unnoyon genotype in all the treatments [1]. BARI Tomato-3 showed the minimum value in most of the cases. Root and shoot parameters like root length, shoot length, shoot fresh weight, root fresh weight, shoot dry weight, root dry weight, ratio on root and shoot fresh weight, ratio on root and shoot dry weight were the highest in BARI Tomato-2, Mintoo and Unnoyon, in contrast, the lowest performance of these traits were revealed in BARI Tomato-16 and BARI Tomato-3 at higher salinity treatment (12 and 16 dSm-1) than other genotypes in most of the cases. The overall results of the experiment exhibited BARI Tomato-2, Mintoo and Unnoyon found to be the more tolerant genotypes at higher salinity stress in respect of days to 50% germination and root and shoot characters than other genotypes.

A factorial experiment was conducted with a completely randomized design to evaluate the effects of planting date and density on calendula herbs and peppermint. It had 3 replicates and was done in Khosroshahr research farm, Tabriz in 2006. Under studied factors were: 3 planting dates (10 May, 25 May and 10 June) in 4 densities (25, 35, 45, 55) of the plant in square meters. The results of variance a nalysis showed that there was 1% probability significant difference between the effects of planting date and bush density on the leave number, bush height and the bush dry weight. But the mutual effect of the plant date in mentioned traits density was insignificant. Regarding the traits mean comparison, the total maximum dry weight was about the 55 bush density in mm. Also, the bush high density in mm causes the bush growth and its mass reduction. When there is the density grain, the flower number will increase due to bush grain in surface unit. Overall, we can conclude that 10 June planting and 45 bush density in mm is the most suitable items and results in favored production with high essence for these crops.
