Abstract

Research has been carried out through the utilization of organic fertilizer to improve the productivity of local maizecultivar originated from South Sulawesi. The study was conducted at the research station of Research Center for Biology,Cibinong Science Center. Corn seed were planted in polybag containing mixture of soil and compost, 6 and 2kg, respectively. The research were carried out by Randomized Complete Block Design arranged in factorial experimentwith four replications. The first factors are three types of local maize namely A: rice corn (pulut beras, BataraKoasa), B: waxy corn (pulut biji, Batara Kamu), C: pulut hibrida (hybrid cultivar). The second factors are 14 combinationtreatment as a mixture of LIPI organic fertilizer (Beyonic-StarTmik, Bio121, EM-121 and MegaRhizo) andanorganic NPK fertilizer. The variables observed were plant growth and production. The results showed that thehybrid cultivar had higher total corn yield productivity compared to the local one, although hybrid cultivar hassmaller plant biomass. Waxy corn (B) accession showed the weight, length and diameter of cob, and also the weightof 100 grains larger than rice corn (A). Fertilization treatments significantly affect the corn-cob productivity which isincludes the weight, length, and diameter units. Fertilization treatments such as EM-121 + (½ dose of NPK), BIO-121 + (½ dose of NPK), and Beyonic + (¼ dose of NPK) showed a good effect on plant, and it was not significantlydifferent with 100% NPK (full doses of NPK). The three corn cultivar showed different responses to fertilizationtreatments.Keywords: local corn, biofertilizer, growth, production

Abstract

Gold mining activities have recently increased in many areas. Contamination with heavy metals, mainly mercury due to illegal mine (PETI) have been in concern to residents around the area. One approach to remediate risks from some toxic metal pollutants is phytoextraction using hyperaccumulator plants. These remarkable plant species accumulate appreciable high concentrations of metals than do normal plants when the normal plants suffers yield reduction from metal phytotoxicity. Possible solution of using indigenous plants for phytoremediation has been studied. Performance of four selected plant species i.e Paspalum conjugatum, Centrosema pubescens, Commelina nudiflora and Mikania cordata were examined. In this study the plants were grown in PETI waste media contaminated with 25.733 ppm mercury (Hg), added with mercury (II) chloride (HgCl2) with different levels of concentrations i.e. 0 ppm Hg (HO), 10 ppm Hg (H10) and 20 ppm Hg (H20). To increase mercury uptake from the media, chelating agent, ammonium thiosulfat (NH4),S2O, was applied with concentration of 0 ppm (KO) dan 50 ppm (50). Plants biomass and mercury accumulation in plant shoots and roots were assessed at one and two months after treatments. The results showed that all of the plant species under study were highly tolerant to Hg. It was indicated by plant normal performances and high biomass production even in the highest level of Hg concentration and high Hg accumulation in the plant shoot and roots that reached 41.860 ppm in the shoot of P. conjugatum (H10 with chelate), 40.054 ppm in the shoot of C. pubescens (H20 no chelate),41.089 ppm in the shoot of C. nudiflora (H10 no chelate) and 42.610 ppm in the shoot of M. cordata (H10 no chelate). At the highest concentration levels of Hg under study there was no effects of toxicity on the plants, indicated by normal plant growth and high biomass production. Higher accumulation of Hg were found in the plants treated with higher level of Hg concentrations.

Abstract

Pulai {Alstonia scholaris (L.) R.Br famili Apocynaceae} is one of the prospective plants due to its multipurpose such as for construction, medicine and handicraft. It is known that pulai can be propagated by seed, cutting or grafting. To have the best performance of seedling in the nursery, we have to study many aspects. One of that aspect is shading tolerance of pulai seedling. This research was conducted to study the effect of 0, 25, 50 and 75% shading on the growth of pulai seedling. The result showed that the best growth of pulai seedlings is on the 0% shading. But in 25-50% shading the growth of pulai seedling are still in good performance, while in 75% of shading the growth have been decreased.

Abstract

Keladi tikus Thyponium flageliforme (Lodd.) Bl. is considered as a wild plant species, because it is not fully cultivated yet. However,now adays it is quite widely used even in its wild status, because it is reported to be traditionally used as cancer cure. Due to its potential uses by the people, there is a need to be developed by cultivation in order to fulfill the demand for raw materials, both for medication and planting materials in research activities. This research was conducted to study the behaviour of keladi tikus when bring to cultivation status. The research is divided into two parts i.e: a) the effect of bulb weight as planting material and 2) the effect of shading on the growth. The result sshowed that bulb weight is not significantly affected the growth. On the 10month after planting the parameter measured is not significantly different. Meanwhile, shading is significantly affected the plant growth. The best growth is achieved on 0% shading, but the growth on 50% shading is still good. The growth on 75% shading has significant decreased.

Abstract

Phytoremediation is defined as a clean up of pollutants primarily mediated by pliotosynthetic plants so its could be used as an alternative technique to overcome contaminated soil and water such an mining ecosystems. These plants have several beneficial characteristics; they have ability to accumulate metals in their shoots and especially high tolerance to heavy metals.Since Indonesia has abundant plant diversity, it is believed that some of them are potential to be used as phytoremediator.This research was carried out to study the potential of three species of grasses in accumulating Pb and Cn. The treatments were arranged on Randomized Complete Block Design (factorial design). The first treatment are species of grass: 1) Cynodon dactylon Pers., 2)Cyperus sp. and 3) Ischaemum timorense Kith.; the second treatment is planting media i.e. 1) tailing soil, 2) soil from wildmining (mining activities run by unexpected miners) and 3) top soil and the third is organic fertilizer: 1) manure, 2) compost and 3) no fertilizer.The resultsshowed that all of the three grasses are potential to accumulate Pb and Cn. Organic fertilizer mixed on planting media is significantly affected the growth of grasses and increasing the accumulation of Cn on leaf of Cyperus sp. and I.timorense. While no evidence in increasing Pb accumulation on all of those three grasses species

Abstract

One approach to minimize risks from some toxic pollutants is phytoextraction using hyperaccumulator plants. These remarkable plant species accumulate appreciable high concentration of pollutants, including cyanide than normal plants. Although cyanide is not categorized as heavy metal, its presence is considered as one of important toxic pollutants in the environment. Detoxification of cyanide contaminated soils and waters with plants seems to be a feasible option. Since plants vary in their ability to accumulate specific contaminants, it is necessary to select plant species that can both accumulate and tolerate the contaminants. This study aims to characterized plants that grow under extreme contaminated media of gold mined tailing belongs to PT ANTAM Cikotok and to analyse their potencies as hyperaccumulators. Saccharum spontaneum which was proven tolerant and dominant in the contaminated site as well as potential in producing high biomass was used in this research. The plants were grown in tailing waste media added by 0, 5 and 10 mg kg-1 CN. Organic fertilizers i.e. manure and compost were applied to increase CN uptake. The results showed that the plants were capable of growing under the highest level of CN. Application of organic fertilizer increased plant uptake. The results indicated that Saccharum spontaneum can be considered as high tolerance and potentially effective in accumulating CN in their roots and above ground portions.

Abstract

Studies on the soil nutrient status of a degraded forest under traditional gold mining have been conducted in a forest area in Bojong Pari,Sukabumi,West Java by analyzing nutrient content of soil taken from degraded forest and also from the adjacent virgin forest as a control. Meanwhile, litter deposits from forest floor were collected to be compared. The result showed that the soil is belongs to clay type with the acidity ranged between (based on H2O 1:2,5) 4,72-4,83.Soil macro nutrient content from degraded forest showed N 0,041%; P 0,059 mg/100 g and K 0,222 ppm, this value are lower than that from virgin forest. The litter deposits ( dry weight) taken from degraded forest are 110,53 g/m lower than the virgin forest (230,42 gAn ).It means that traditional gold mining has changed the nutrient status of the Bojong Pan Forest area.

Abstract

The research was carried out to study the effect of fertilizer on the growth (plant height, number of leaf, length and width of leaf, fresh weight) and flower production of velvet leaf ? genjer {Limnocharis flava (L.) Buchenau} and to analyze nutrient potential i.e. proximate and amino acids in leaves and flowers (including stalk). Seedlings of velvet leaf with 6 leaves were planted and fertilizer treatments were applied in one week after planting. Planting media were mixture of soil:manure:compost (2:1:1). The fertilizer treatments included control, NPK2, NPK4, MU2, MU4, POH2 and POH4. The plants were cultivated until 5 Weeks After Fertilizing (WAF). The results showed that velvet leaf can be successfully cultivated in plastic pot on planting media added with fertilizer. The highest plant growth and flower production were in the MU4 treatment (NPK Mutiara 27-5-5, 4g/plastic pot). Application of starTmik Biofertilizer 4cc/50cc water/plastic pot showed as good performance as the MU4 treatment, however, the dosage and application frequency need to be increased. The proximate analysis on leaves and flowers showed considerably high percentage of crude fibre (1.56% and 1.42%), protein (2.04% and 1.98%) and carbohydrate (3.16% dan 2.98%). Amino acid analysis revealed 9 numbers essensial amino acids and 8 number non essensial amino acids.
