Abstract

Phytoremediation is defined as cleaning up of pollutants mediated primarily by plants. It is an emerging technology for environmental remediation that offers a low-cost technique suitable for use against different types of contaminants in a variety of media. Phytoremediation is potentially applicable to a diversity of substances, involving hyperaccumulators heavy metals and radionuclides. It is also applicable to other inorganic contaminants such as arsenic, various salts and nutrients, and a variety of organic contaminants, including explosives, petroleum hydrocarbons and pesticides. At least there are one taxon of plant as hyperaccumulator for Cd, 28 taxa for Co, 37 taxa for Cu, 9 taxa for Mg, 317 taxa for Ni, and 11 taxa for Zn. Extensive progress were done in characterizing physiology of plants which hyperaccumulate or hypertolerate metals. Hypertolerance is fundamental to hyperaccumulator, and high rates of uptake and translocation are observed in hyperaccumulator plants. Hyperaccumulator plants and agronomic technology were undertaken to improve the annual rate of phytoextraction and to allow recycling of soil toxic metals accumulated in plant biomass. These techniques are very likely to support commercial environmental remediation. Most phytoremediation systems are still in development, or in the stage of plant breeding to improve the cultivars for field use. However, application for commercial purposes has already been initiated. Many opportunities have also been identified for research and development to improve the efficiency of phytoremediation.

Abstract

Water contamination with heavy metals, mainly mercury and cyanide (CN) due to small scale of public mines and large scale of industrial mines have been in concern to residents around the area. Surveys of heavy metal contamination in aquatic environments, such as rivers and paddy fields over two gold mine areas in West Jawa were conducted and possible solution of using indigenous plants for phytoremediation was studied. The results showed that most of the rivers and other aquatic environments were affected by gold mine activities. Rivers, ponds, and paddy fields around illegal public mines were mostly contaminated by mercury in considerably high levels, such as paddy fields in two locations (Nunggul and Leuwijamang, Pongkor) were contaminated up to 22.68 and 7.73 ppm of Hg, respectively. Whereas rivers located around large scale industrial mines were contaminated by CN. Possible solution of cleaning up by using green technology of phytoremediation was examined. Some plant species grew in the contaminated sites showed high tolerance and potentially effective in accumulating cyanide or mercury in their roots and above ground portions. Lindernia crustacea (L.) F.M., Digitaria radicosa (Presl) Miq, Paspalum conjugatum, Cyperus kyllingia accumulated 89.13, 50.93, 1.78, and 0.77 ppm of Hg, respectively. Whereas, Paspalum conjugatum, Cyperus kyllingia accumulated 16.52 and 33. 16 ppm of CN respectively. Key words: phytoextraction, contaminants, cyanide, mercury

Abstract

Contamination of mined soil and water affects not only to agriculture system but alsofood chains and epidemiological problems. As soil metal can not be biodegraded,remediation of soil heavy metal risks has been a difficult and expensive goal. Presentlythere are several different strategies available for the clean up and restoration ofcontaminated soils. One approach to minimize risks from some toxic pollutants isphytoextraction using hyperaccumulator plants, known as phytoremediation. In thisresearch Centrosema pubescens was studied to examine its potency ashyperaccumulator against cyanide. Although cyanide is not categorized as heavymetal, its presence is considered as one of important toxic pollutants in theenvironments. Detoxification of cyanide (CN) contaminated soils and waters withplants seems to be a feasible option. Centrosema pubescens which proven tolerant anddominant in the CN contaminated environment was used in this research. The plantswere grown in tailing waste media added by 0, 10, 20 and 30 ppm CN. Different pHlevels were applied, i.e.+ 6 and +5. The results showed that the plants were capable ofgrowing under high level of CN. The results indicated that Centrosema pubescens canbe considered as high tolerance and potentially effective in accumulating CN, i.e up to3.564 ppm in roots and up to 3.564 ppm in shoot with concentration ratio (shoot/root)up to 1.13. The plants also indicated high tolerance by producing high biomass underhigh level of CN, i.e up to 36.517 g (under 20 ppm CN).

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

Water is the most crucial factor in affecting plant growth and production.In order to assess the complex relationship between plant and water,a dynamic model of crop growth was constructed by interlinking plant growth and soil water models.The growth model mainly consists of physiological processes, i.e.photosynthesis, respiration, partitioning, leaf growth and phenological development.The photosynthesis and partitioning models are based on SUCROS, extended in two ways, the calculation of light use efficiency as a function of air temperature and extinction coefficient as a function of LAI.The development model was calculated based on thermal time concept.Water balance model comprises evaporation and transpiration as water losses, and rainfall and irrigation as water sources at 1 m - depth. Evaporation was based on Penmann Monteith formula.Both models were linked by relating the degree of growth reduction to water deficits. Simulation results showed a good agreement with observed data in predicting soil water deficits and crop water use for all of the treatments, i.e.irrigated, irrigated just after flowering, dry and rainfed.Despite the model predicted soil water considerably well, it tent to overestimate soil water deficits in the beginning of the growing period for both years. The results also showed a good agreement between simulated and observed dry matter production,especially under irrigated and rainfed conditions.

Abstract

Procrastination is behavior that is often carried out in everyday life. One of them is in the wor ld of education, where the students deliberately delaying to begin or complete the tasks assigned in school or so-called academic procrastination. Students often do it because, they are waiting for the right time to work with focus and uncomfortable study flow academic or not conditions. Academic procratination scale with coefficient of pearson product moment correlation betwen 0,303 to 0,638 and coefficient of reliability 0,899 and to scale the flow academic 0,313 to 0.681 with a reliability coefficient of 0.93. Thus, all the scale is reliable to use. This study uses 120 students were selected by stratified random sampling of 759 students. The regression analysis of predictors obtained Freg value of 8.319. Thus, there is a highly significant relationship between academic procrastination with academic flow. Flow academic influence forming 6.59% of the academic procrastination behavior. Thus, it can be concluded that the hypothesis that there is a relationship between acadeic with academic procrastination accepted at significance level of 1%, which amounted to -0.257 r xy is greater than can be predid r table 5%. This means that the higher academic flow conditions of the students, the lower academic procrastination behavior of the student, and vice versa when the high academic procrastination behavior so low flow academic.

Abstract

Salah satu cara untuk menunjang keberhasilan guru dalam proses belajar mengajar di kelas yaitu dengan menyediakan alat bantu yang disebut sumber dan media belajar. Sering kali penggunaan sumber dan media belajar tak sesuai dengan materi yang diajarkan sehingga mengakibatkan guru kurang maksimal dalam menyampaikan materi. Kurangnya pengetahuan tentang perkembangan ilmu pengetahuan juga menjadikan guru kesulitan dalam penggunanaan sumber dan media belajar di sekolah. Metode analisis yang digunakan ada tiga tahap yaitu reduksi data, penyajian data, dan verifikasi data. Untuk pemeriksaan keabsahan data, peneliti menggunakan metode Triangulasi, dalam tehnik pengumpulan data. Hasil penelitian menunjukkan bahwa guru PAI di MTs Hidayatussubban masih belum dapat menggunakan atau mengoperasikan sumber belajar yang ada disekitar lingkungannya secara tepat, dan penggunaan media yang kurang tepat juga menjadikan siswa kurang berkonsentrasi dalam menerima pelajaran.  .
