Abstract

Indonesia Presidential Regulation No. 5/2006 on National Energy Policy suggests that the government should speed up the implementation of the use of alternative energy or fuel substitution. Biofuel synthesis is one way to overcome the shortage of energy and reduce global warming due to the use of fossil fuel. Biofuel can be produced from a variety of vegetable oil. Beside palm oil, nyamplung oil can be used to produce biofuel. The technically main obstacle in producing biofuel is the availability of the catalyst. The availability catalyst are only imported and expensive. Researchers have tried to engineer a new type of catalyst that complete the weakness of zeolite based catalyst. The study was conducted through experimental approaches, testing and observations and conducted the correlation of experiment variables with the quality of the resulted catalyst. The experiment was done by synthesizing catalyst and testing it to produce biofuel from nyamplung oil. The focus of the research is directed to the effect of operating variables on the composition of the resulted biofuel and obtain catalyst performance condition and optimum condition to produce biofuel in the fixed bed reactor. The resulted catalyst can change the nyamplung oil into biofuel. Biofuel from nyamplung oil cracking process showed that the composition is biogasoline, biokerosene and biodiesel. Biodiesel fraction is the highest fraction of the biofuel produced. The highest percentage of biodiesel at a temperature of 400°C was 60%, while the lowest percentage of biodiesel at a temperature of 300°C was 48%. Products density was in the range of 0.81 to 0.86 g/ml. The highest density occured at a reactor temperature of 300 °C was 0.86g/ml. The higher the nitrogen gas flow rate the more the biodiesel formed. At a temperature of 300°C and a nitrogen flow rate of 100 ml/min, the composition solar achieved was 60%.

Abstract

Cellulose acetate/polyethylene glycol 200 (CA/PEG) membrane with ration 80/20 (wt%) was modified with varying amount of silica in many concentration (1-5% w/v). CA/PEG-200 membranes were characterized for their hydrophilicity, functional groups and permeation properties. The increasing of CA at CA/PEG membrane make membrane more dense and hydrophilicity of membrane decreases. Membrane hydrophilicity, permeate flux, permeability, and salt rejection increase with the increasing of silica concentration in CA/PEG membrane. The experiment results show that the highest salt rejection was obtained when 5% silica was added into CA/PEG (80/20) membrane.

Abstract

The construction industry has a very important role to the growth of a country. The unique characteristics and dynamic nature of the construction industry lead to a dangerous condition and prone to accidents. The death rate due to accidents in the construction industry in 2015 increased by 4% compared to 2014. The number of occupational accidents in Indonesia from year to year experienced a trend of an increase of 5%. Unsafe behavior of workers was the main cause of 88% of accidents in the construction site, 10% due to unsafe conditions, and 2% due to the unavoidable things. In addition, the complexity of construction equipment and unsafe environment significantly determined the type of accident and severity of injuries. This study aims to propose the probability model to predict the construction worker accidents in construction projects. To improve the accuracy of the assessment of workplace accidents, Bayesian Belief Networks used as a study analysis to represent the relationship among unsafe factors such as unsafe behavior factors, unsafe environment and unsafe equipment that lead to accidents. The data was collected through project site survey, questionnaire, and interview to OSH Managers in ten construction projects. The validation is done by applying the model on four case of a high rise building. This finding shows both the probability and accurate prediction of work accidents with APE mean is 4,564 that is useful to assist the practitioners and all stakeholders especially those directly involved in construction industry and to get some recommendations steps and preventive actions in order to minimize the occurrence of fatal work accidents and improve occupational safety and health (OSH) as well as to contribute knowledge about the factors that influence the occurrence of accidents.

Abstract

The Sea Surface Temperature (SST) retrieval from satellites data has been available since 1980’s both temporally and spatially. Some researchers have established SST inversion models depending on the correlation between the TM/ETM+ TIR radiance and the in-situ data. The objective of this research is to evaluate the performance of Landsat 8-estimated SST from 4 existing algorithms: Planck, Mono-Window Algorithm (MWA), Syariz and Split Window Algorithm (SWA) algorithms on  4 different tested areas: Eastern Bali, Bangkalan, Bombana and Poteran waters. Algorithm of Syariz dan SWA produced acceptable accuracy on all tested area with the NMAE ranged at 0.2-19.6% and 3.4-9.9% for Syariz and SWA, respectively. However, MWA and Planck produced NMAE larger than 30% on Bali and Poteran waters. Following the successful of SWA algorithm, the same algorithm was developed using insitu data collected on Poteran waters. The estimated SST by the developed algorithm produced acceptable accuracies on all tested water areas with the NMAE ranged from 0.401% to 16.630%. It was indicated that   Syariz, SWA and the developed algorithms were applicable for SST retrieval on all tested waters

Abstract

Soybean (Glycine Max) is one of the agricultural commodities that still had particularly low production rate on a national scale in Indonesia. Despite the demand for the soybean it’s increasing along with the population growth in Indonesia. Thus, the need of soybean which mainly as main ingredient of tempe and tahu is still filled from importers. These problems can be solved by the research of applying artificial light technology in the agricultural sector so it would help optimize soybean growth. The purpose of this research is determines the effect of Blue Light and Red Light Emitting Diode (LED) lighting on the growth of soybean (Glycine max). Soybeans were grown in uniform boxes that had controlled temperature and humidity with regulated soybean seeds, soil, and planting methods. Based on the results from the research that had been conducted on the growth of the soybean, it is determined that most optimum soybean plant is using the lighting ratio of the red LEDs 75% and blue 25% with a height of 15 cm in the ninth day and the chlorophyll concentration is 52,4265953 mg/l. But plant with sun source lighting is better than using LED, it is about 118,8138334 mg/l. Based on the result that had been obtained, this research can be used as reference in the making of modern artificial light for soybean for research development in agriculture especially on soybean commodity which could support government efforts in suppressing important soybeans and meet domestic soybean demand using national production.
