Abstract

Tree growth is closely related to the process of photosynthesis. So far the rate of photosynthesis in elements of secondary forests has not been known, especially in pioneer species. At the same height of the place and micro-climate conditions, the rate of photosynthesis of pioneer species of secondary forest has a different rate of photosynthesis. This study aims to determine the ability of the rate of photosynthesis of some secondary forest pioneer tree species in order to support reforestation efforts on degraded forests and at the same time looking for the kinds of pioneers who have a high absorption of CO2 gas in an effort to reduce global warming caused by emissions CO2 gas in the air. The survey results noted there are 6 common pioneer tree species grow at the sites. Trema orientalis had the highest CO2 assimilation value which is equal to 20,350 μmol m-2s-1, followed by the Macaranga triloba (17,198 μmol m-2s-1), Omalanthus populneus (14,097 μmol m-2s-1), Mallotus paniculatus (13,118 μmol m-2s-1), Macaranga tanarius (12,862 μmol m-2s-1) and Weinmannia blumei (10,058 μmol m-2s-1). Research conducted during the rainy season (September 2010). During measurement, the light radiation in the upper leaf surface between 63,583 to 363,750 μmol m-2s-1, air temperature 21,8 to 26,70C, air humidity 75,8-89,8%, light intensity 2483,3 to 28701,7 Lux, soil pH 5,8 to 6,3 and soil moisture between 50,7 to 71,7%.

Abstract

Up to now, the majority of people treat plastic waste by burning and disposing it directly to the surrounding environment. The burning of the waste causes air pollution due to toxic compound called dioxin which is harmful for human health. Meanwhile, the dumping of plastic waste into water bodies can causing some negative effects such as the clogging of water duct or river which may lead to flooding. Annually, the number of plastic bag used can reach 500 million – 1 billion, which is equal to 10 fold wrapping of earth surface (Nitizen, 2008). The best handling of plastic waste are using reuse or recycle methods which are environmentally friendly and at the same time can gain economical value1). The study is aimed to: 1) understand the capability of oven distillator in processing plastic waste into plastic grain and liquid smoke, 2) understand the influence of liquid smoke towards wood durability, 3) understand the price of the oven distillator and the corresponding break even point (BEP).The study was an experimental one and employed pre test and post test with control group design, and simultaneously assessing equipment’s production capacity. The data was analyzed descriptively and analytically with Anova test and t-test at 95% level of significance.The results show that oven distillator capable for processing 97,3% of plastic waste into plastic grain, while the rest was converted into liquid smoke. The liquid smoke was proved affect wood preservation (anova test, p<0.001), and have similar quality compared with varnish use (t-test, p=0,764). The cost analysis shows that the distillatory raise economical value of the waste by 217,66%, and The BEP would be reached in 68 days if 12 kg plastic is processed daily. It is advised that he oven can be used by general community or home industries for applying green and high economically value of plastic waste processing.

Abstract

Carbon dioxide (CO2 )gases that dominated by anthropogenic activities causevarious negative impacts on the environment and surroundings due to increasing itsconcentrations in the atmosphere. There are some techniques to mitigate againstthe increase of CO2 which one is the utilization of phytoplankton cultured in a photobioreactor (FBR) as an natural absorber. In this study, the influence of input gas CO2flowrate on Chlorella sp at multiple tubular air lift photobioractor (FBR) was measuredin milk factory field. The CO2 flowrate continuesly was controled by 2 l/min and 1.5 l/mduring experiment. Result showed that Chlorella sp. have a good adapted ability of CO210-15% vol industrial emition. The experiment result stated that reactor capability atFBR-1 was lower than FBR-2. The reactor capability at FBR-1 and FBR 2 were 0,78 ±0,25 and 0,92 ± 0,36 g/l. media/day.

Abstract

Pesticide Residue was Affect Bacterial and Fungal Population in the Greenhouse Soil Condition. Bacterial and fungal inhabitants were examined through agriculture soil samples. Survival of microorganism in soil was important to evaluate the mineralize process. In the greenhouse experiment, bacterial and fungal population noticed as essential assessment in soil healing with long lasting pesticide (A-soil) after the soil treated with powdered rice straw as organic matter amendment, toxic degrading bacterial as inoculants, and the both of those mixed treatments. That residue implication also assessed to B-soil (as free pesticide soil) then revised with pesticides, and also treated as followed for A-soil. Potential degradation of indigenous microorganism examined all through as setting of control (B-soil) to recognize of its original population.Those of treatments evaluated through microbial survival along 12 weeks incubation in green house environment. Bacterial and fungal populations was affect to become fluctuated along with incubation period as due to the treatments. Bacterial inhabitant was considerably higher compared to fungal population. Correlations were significantly difference with bacterial (p = 0.6654) as well as fungal (p = 0.9029) population in A-soil evaluated to B-soil habitats since the mixed treatments present to both of the soil (p0.005 = 0.6310). Organic matter alteration and certain microbe input was needed in soil contain pesticide, because at the same time the survival of microbes possibly mineralized organic matter, as well as the pesticide residue.

Abstract

Paddy rice canopy hyperspectral was measured by using ground-based spectroradiometer and HyMap sensor onboard an airplane from 350 nm up to 2500 nm in the same timethat covered various growth stages. Coinciding with hyperspectral measurement, biophysical parameters such as leaf area index (LAI), SPAD value were measured onground during the airplane passed over area of interest (AOI). Rice yield was measured at the time of final harvesting by random selected yield (ubinan method) for each sampling area. In finding the best correlation among canopy hyperspectral reflectance with crop development, optimal individual waveband explored with involving all possible waveband combinations to obtain the best fitted two-pair waveband related to crop biophysical parameters. Normalized Difference Spectral Index (NDSI) was appliedfrom spectral transformations (obtained from optimal waveband selected by exploring all possible waveband) to improve sensitivity analysis on plant. Canopy hyperspectralprovided information about plant, soil and water background when plant canopy don’t completely cover soil surface yet. The present study was directed to examine spectralindices and establish the relationships between biophysical parameters of rice by using partial least square regression (PLSR) technique.

Abstract

Organic Fertilizer in the form of Granule Organic Fertilizer (POG), which is enrichedwith functional microbes, has been produced in great quantities nowdays, because it isexpected to improve the physical, chemical, and biological properties of soil at once. Thecondition of land degradation that has become a big concern, in spite of the low organicmatter in the lands, more encourage the increasing of POG production to be applied verysoon into agricultural lands in Indonesia. However, how is the conditions of the POGplant, what kind of raw material that will be used and how does the production processitself run, would be very excited to be analysis in order to develop the future of POGplant. Results showed that the POG plant conditions generally contains of the facilitiesand infrastructure that support the physical/ mechanical process, that is not passed thebiological process first which is known as composting process. The raw materials thathas been used could not maximize organic materials potentials that exist and only relyon animal waste and sugarcane waste (blotong) from sugar mills, as the main mostlyused raw material. While the common POG manufacturing process consist of the mixingof the raw materials, granulation process, drying, cooling, screening, enrichment withfunctional microbes and packaging.

Abstract

The green revolution in the 19th century, has met expectations in an effort to increase the productivity of food supply, in the world at least in Indonesia. In the course of time the green revolution movement has given the systemic impact not only on the degradation of ecosystems, but also the productivity of land, especially paddy fields due to the use of agrochemicals that have been over threshold. The impact on soil in Indonesia become ill, there is a change of soil structure, become poorer and finally lost as the land carrying capacity of production. Systemic Degradation covering 18 000 ha of wetland, contamination levels of heavy metals such as Hg, Fe, Cd, Cu has been on conditions that endanger human health also pesticide has an impact resistance to pests.Recovery efforts of agricultural land, will take time, and cost is not cheap. Various studies have been done, to remediation land by using acid-humic substances, and gives results quite encouraging, because it’s quite effective, efficient and inexpensive, compared with conventional methods is to provide an organic material such as kompost.

Abstract

Nepenthes albomarginata Lobb ex Lindl. is a carnivorous plant, distributes in several regions in Indonesia. The plant population decreases drastically because of over exploitation and ruining nature habitat. Plant propagation by nature and cutting are not enough to rehabilitation its population. In vitro culture of N. albomarginata was carried out using plantlets grown from the seeds in vitro. Plantlets were cut to became two part explants, consisted of shoot tip and under-shoot tip cuttings. These cutting explants were grown on Murashige & Skoog (MS) media with addition of plant growth regulators of 6-benzylaminopurine (BA), combined with or without-naphthalene acetic acid (NAA) or 2,4-dichlorophenoxyacetic acid (2,4-D) at 1 mg/l. Shoot tip cuttings of N. albomarginata formed double multiple shoot 25,00% on control; formed triple multiple shoots 25,00% onBA 1 mg/l treatment; formed callus 37,50%, triple or quartet shoots 25,00% and rooted plantlets 25,00% on BA 1 mg/l + NAA 1 mg/l treatment. The under-shoot tip cuttings ofN. albomarginata formed double – triple shoots 25,00% and rooted plantlets 37,50% on control; formed double – triple shoots 25,00% and rooted plantlets 12,50% on BA 1 mg/ltreatment; formed callus 12,50%, double - pentacle shoots 37,50% and rooted plantlets 25,00% on BA 1 mg/l + NAA 1 mg/l treatment. 2,4-D 1 mg/l or its combined with BA 1mg/l treatment caused deadly shoot tip or under-shoot tip explants. The combination of BA 1 mg/l + NAA 1 mg/l was the best treatment for producing callus, multiple shootsand rooted plantlets of N. albomarginata.

Abstract

Ecocentrism paradigm in development are intended to ensure the sustainability of water resources in the future for future generations. The research methodology was conducted with the model approach to drinking water users willingness to pay for environmental services (YWTP). The results in Analysis Willingness to Pay in Drinking Water Management in the Upstream Watershed Cisadane illustrates that the existence of a positive response from drinking water users (entrepreneurs) to be willingness to pay for environmental services (YWTP) as payment and reward for environmental services to the public because it is influenced by the presence and the beneficiaries are significantly linearly with level of education (sig. 0.041) and Variable in YWTP education significant at 95% confidence level. Policy implications of this research that the user (downstream) is willingness to pay (WTP) for environmental services with averaging Rp1 538.65 per m3 as payment or reward for environmental services to society (upstream), so the Government (Local) PES has a potential revenue to fund conservation of Rp106.94 billion per years, but in current conditions the government only earns Rp20.57 billionper year, so that only reached 19.24%.

Abstract

Liquid Gas Vehicle (LGV) is one of an alternative hydrocarbon fuel, which is the dominant composition are propane and butane, and now is already available in the market. With low sulfur content and high octane number, theoritically vehicle emissions using LGV are better than gasoline. But it is need a good mixture ratio of air to LGV (AFR) in the gas mixer before enter to the engine. This paper describes a study that compared emission test results from gasoline engine using LGV with standard mixer and Pertamax market fuel. The study was based on the vehicle chassis dynamometer test results according to the UN-ECE R83-04 test cycle standard on both cold and hot starts. The test results have shown that on urban cycle CO and HC emissions of Pertamax fuel was better than LGV on both cold and hot starts. Whereis on extra urban cycle CO emission of LGV fuel was better than Pertamax. NOx emission of LGV fuel was very low and practically undetected for all test condition. Utilisation of LGV fuel reduce CO2 emission in order of 15% for urban drive cycle for both cold and hot start, and in order of 9,2% for cold start and 10.5% for hot start for mixed cycle.
