Abstract

In this work medang wood (Cinnamomum spp.) was pyrolyzed to produces wood vinegar. The effect of several parameters including the wood particle size, pyrolysis temperature, and pyrolysis time on the pyrolysis efficiency was tested to identify the optimal wood vinegar production conditions. The efficient response surface methodology (RSM) with the Box-Behnken design (BBD) was used for modeling and optimization of the process parameters. RSM used three variable designs namely particle size of wood of 2.38, 3.36, and 4.76 mm, respectively, pyrolysis temperature of 370, 400 and 430°C, respectively, and pyrolysis times 90, 120 and 150 minutes, respectively, with the total of 15 experimental runs. The responses of the BBD fitted with a second-order polynomial equation, illustrating the wood vinegar yield was Y = 15.20 + 0.31 X1 + 5.00 X2 + 0.48 X3 – 1.84 X12 – 1.18 X22 + 0.63 X1.X2 + 0.35 X1.X3 + 0.31 X2.X3 – 0.27 X3.X3.  The optimal conditions found to be at the particle size of wood, pyrolysis temperature, and pyrolysis time were 4.76 mm, 475 °C, 195 minutes, respectively, and yield of wood vinegar was 22.90%.

Abstract

Banjarmasin is dominated with the combination of land and river, which resulted many riverside areas in the city. These areas are functioned as settlements area, as well as commercial and public areas as the focus of the city’s development and the local’s daily activities. However, the rapid development in Banjarmasin still giving less attention to the development of green open spaces, despite the local connection with the river. Therefore, this research aimed to identify the local perception of green open space in the riverside areas of Banjarmasin through descriptive qualitative analysis. Questionnaires and observations in five study areas were done to obtain the local perception. The results show that the highest local perception index is for the  social aspects for 87,2 points and the lowest local perception index is the spatial planning aspects for 42,6 points. Banjarmasin needs to focus more on the spatial planning of green open spaces in riverside areas and enhancing the opportunity for locals to participate in any spatial planning process (participatory planning).

Abstract

The development of nutmeg (Myristica fragrans Houtt) community forests needs to be supported by high-quality seed procurement, both physical, physiological, and genetic quality. Physically it can be done by morphological analysis in the form of length, diameter, and weight of seeds. Meanwhile, to determine the physiological quality, one of which is by observing germination. This research aimed to identify the morphology of seeds and germination of nutmeg (M. fragrans Houtt.) from different seed sources in the development of nutmeg community forests in Bacan, South Halmahera. The results showed that the morphology of nutmeg seeds in the shape, color, and skin surface variables at the three locations (Amasing, Papaloang, and Babang) obtained the same results, namely oval, brownish-black and shiny. Whereas in seed length, nutmeg from Papaloang has a longer seed size than seeds from Amasing and Babang. In the germination parameter values, seeds from Papaloang were found to have the highest value, namely the percentage of germination (K = 35%), peak value (PV = 0.56), average daily germination (MDG = 0.56), germination value (NK = 0.31 ).

Abstract

Among various bioremediation methods, bioaugmentation is the one which frequently used. In this study, bioaugmentation was conducted by utilising Pseudomonas aeruginosa, Bacillus cereus, and Brevibacterium flavum. Many studies on and implementations of this method have been conducted. However, this method still needed to be studied especially with reference to its implementations to small automotive workshops, which their number was increasing, as the sources of the soil contamination. The objective of this study was to identify the most effective bacteria in removing total hydrocarbon content (TPH) from contaminated soils and to understanding several characteristics of the method. Laboratory research was set up and the experimental design was complete randomised design (CRD) with three replications. Statistical test of Anova with α 5% was carried out to evaluate the results of the study. The treatments of this study were three species of bacteria which were inoculated separately into the contaminated soils. The parameters were TPH, pH and the density of bacteria consortiums. The highest effective removal of TPH was showed by P. aeruginosa, 64,1% (δ+2,61%), followed by B. flavum and B cereus. This treatment had pH dropped two points and the density of bacteria consortium increased 6-10 times. The main limitation of this study was the number of parameters which was a few resulting difficulties in understanding the hydrocarbon degradation processes. The results of this study may give significant contributions to managers of small automotive workshops in cities which currently are not managed their spills properly.

Abstract

Law No. 18 of 2008 on Waste Management prioritizes waste handling nearer the generator by considering economical value remained. In Depok City, waste handling at the community level has been performed at the Waste Treatment Unit (WTU) and waste bank. WTU focuses on organic waste treatment, while waste bank for inorganic waste recycling. The paper aims to identify waste generation and to evaluate the operational activity of the facilities. The sampling procedure proceeded for 8 days consecutively for 14 WTUs and 1 day for 7 waste banks applying stratified random sampling from a total of 30 WTUs and 428 waste banks operated in Depok City. Waste received daily were varied between 95,32-1.436,98 kg of organic waste at each WTU and 69,65-868,40 kg of inorganic waste at each waste bank. The variation of waste received was proportional to the number of inhabitants served and the character of the community surrounding the facility. The performance of the facilities could be improved including through promotion and financial support attained from the retribution. Waste handling at the community level could reduce the amount of waste transported to the Final Disposal Site (FDS) and reduce land required for FDS which becomes difficult to find especially in big cities in Indonesia.

Abstract

Biopore infiltration hole are hole made for run-off flow which if allowed to cause erosion and can remove the topsoil, causing soil fertility to be reduced. The use of biopori infiltration holes can be maximized by adding organic matters into the hope that in addition to absorbing water it can increase soil fertility. The liquid waste of tofu and meranti litter is an organic matters are used in this study, by adding organic matters to the biopori hole. This study aims to look at the effect of providing organic matters in the biopore hole derived from tofu and litter liquid waste on the value of pH, C-Organic, and post-mining CEC. This study was an experimental study in the field using a completely randomized design of one factor, namely organic matters with six levels, namely without organic matters and using 25 g, 50 g, 75 g, and 100 gr organic matters given to the biopori hole in incubation for one month later Soil samples taken were analyzed for pH, C-organic, and CEC. The results showed that the treatment only affected the soil's pH value. Organic material provided in the biopori hole is thought to have not completely decomposed, causing the soil around the biopori infiltration hole to remain acidic. The acidity of the soil is due to the gases produced during the decomposition process. Changes in soil pH ranged from 4.36 to 4.65 by administering 75g of organic matters from tofu liquid waste and meranti litter. This research is useful in post-mining land reclamation in increasing soil fertility, with the improvement of soil chemical properties such as pH will slowly improve the physical and biological properties of the soil so that it can be used as cultivation land.

Abstract

One of the causes of the declining productivity of rice is sheath blight disease caused by the mold Rhizoctonia solani Kuhn. Control of sheath blight disease that is often done by the farmers is by using chemical pesticides (fungicides), which caused environmental problems. One way to reduce the use of pesticides is to biological control by using antagonist bacteria. This study aimed at in vitro test of rhizobacteria in preventing the development of sheath blight disease in rice plants. This research was conducted in the Phytopathology laboratory of Plant Protection Department of Faculty Agriculture, University of Lambung Mangkurat Banjarbaru from March to May 2018. The experiment used a randomized block design with three groups consisting of eight types of rhizobacteria isolates: (r1) Pseudomonas aeruginosa (Barito Kuala), (r2) Bacillus megaterium (Hulu Sungai Tengah), (r3) Azotobacter sp. (Barito Kuala), (r4) Pseudomonas sp. (Hulu Sungai Selatan), (r5) Flavobacterium sp. (Tanah Laut), (r6) Bacillus bodius (Barito Kuala), (r7) Pseudomonas aeruginosa (Hulu Sungai Selatan), (r8) Necercia sp. (Tanah Laut). The results showed that all rhizobacteria have the ability to inhibit the development of R. solani with different percentages of inhibitions. Pseudomonas aeruginosa (Barito Kuala) was the most effective rhizobacteria in inhibiting the development of R. solani.
