Abstract

BIOETHANOL PRODUCTION FROM COCONUT HUSK USING the WET GAMMA IRRADIATION METHOD. The use of coconut husk has only been used as a material for making handicrafts such as ropes, brooms, mats, and others or just burned. The combustion of coconut husk can cause air pollution. In fact, coconut husk can be used as a raw material for bioethanol production so that the beneficial value of coconut husk will also increase. One way of bioethanol production from coconut husk is by irradiating the coconut husk. The coconut husk irradiation technique to be carried out in this study is the wet irradiation technique. Wet irradiation is carried out to accelerate the process of bioethanol production because at the time of irradiation, cellulose has been hydrolyzed and glucose has been formed so that it is more efficient in time and use of the material so that the cellulose hydrolysis process is not necessary. The coconut husk samples were wet because they were mixed with 4% NaOH and were irradiated using a gamma irradiator from STTN-BATAN Yogyakarta with a dose of 30 kGy and 50 kGy and 0 kGy (or without irradiation). Then the sample is fermented with the fungus Saccharomyces Cerevisiae from tape yeast to form ethanol. Ethanol is purified and then analyzed for concentrations using pycnometric and refractometric methods. The result is that the highest ethanol content is without irradiation (0 kGy), this is due to the low dosage used. However, the main point in this wet method research is evidence of hydrolysis of cellulose by the formation of gluoxane after irradiated wet coconut husk, and with Fehling A and B analysis, brown deposits are seen proving that glucose has been formed.

Abstract

SAFETY ASSESSMENTS FOR SUPPORTING THE APPLICATION OF NUCLEAR TECHNOLOGY IN INDONESIA AND A COMPREHENSIVE STUDY ON HIGH NATURAL RADIOACTIVITY AREA. Historically BATAN was established to investigate the negative impacts of nuclear explosions previously conducted in the Pacific area. However, this governmental institute is presently tasked to carry out research and development as well as services in the field of radiation safety and metrology. Therefore, this study aim to determine the activities carried out by BATAN in assessing the safety of workers and the environment. For instance, a standard source of dosimetry laboratory (SSDL) is used in calibration services to successfully support radiotherapy, with the highest achievement in the Designated Institute (DI) for Ionizing Radiation. The health research covers the application of gamma rays to create malaria vaccine, diagnose metabolic diseases with nuclear medicine techniques, and microdosimetry through radiodiagnostic assessment. This study also determined the effective dose and epidemiological study of radioecology and radiation biology in Mamuju (HBRA), which provides a unique opportunity to examine the health effects of chronic low-level radiation exposure to humans. Furthermore, the authors collaborated with Hirosaki University to obtain valuable information on the essential need to assess the health and physical status as well as cytogenetic and deoxynucleotide acid (DNA) damages in the lymphocytes of local populations. Dosimetry study was conducted by direct measurement in the field area by analyzing external radiation exposure of indoor and outdoor gamma dose rate. The internal radiation assessment was conducted by taking urine and inhaled air (radon) from the residents. Studies through the cytogenetic response supported by γ-H2AX, G0, and G2 micronucleus assays and TP53 showed no impacts on the natural radiation with significant differences compared to the control. Marine radioecology studies and radionuclides monitoring throughout the Indonesian archipelago showed no negative impacts as well. Nuclear emergency practice needs to be routinely conducted in the Center for strengthening safety and security cultures.

Abstract

ENVIRONMENTAL RADIOLOGY AND QUALITY ASSURANCE FOR NPP SITE SELECTION. This research briefly explains environmental radiology and quality assurance for NPP sites compiled from regulations, standard documents, and national and international literature. The selection of sites on the coast needs to be performed through research concerning local meteorological conditions with radioactive elements distributed to humans and the surrounding environment through the air and water body. Environmental radiology measurements and monitoring need to be programmed and implemented starting from the initial stage of site selection to the decommissioning. Quality assurance programs for sample measurements and environmental radiology have to be established to ensure the validity of measurement results and have to be reviewed and verified by independents which indirectly involved in measurement and research.

Abstract

RISK MANAGEMENT of Industrial Radiography Personnel Certification Activities to Ensure Worker Safety and Health. The increasing use of radioactive substances and other radiation sources in the Indonesian industry for non-destructive testing lead to a rise in the need for radiographers. In carrying out certification activities, NQSC utilizes radioactive sources in the form of gamma rays from X-ray appliances. Therefore adequate risk management to ensure the safety and health of participants is needed. The risk management process carried out by PSMN uses the hierarchy principle at ISO 45001 and other preventive measures regulated in the IAEA Safety Guidelines, with the measures evaluated periodically using dose reading data. The dosage results on workers and examinees showed that the dose value is below the allowable value with a Dose Limit Value (NBD) of no more than 20 mSv per year. This means that the risk management measures guarantee worker safety and health in the certification activities of industrial radiography personnel in PSMN.
