One of the primary sectors that contributes to green house gas emissions is land use changes. Bogor Regency is one of the districts close to the capital city and industrial areas so that the intensity of land use changes are very dynamic. This study aims to determine the dynamics of land use changes and CO2-eq emissions from land use change in 2000 to 2014 in Bogor. In the period 2000-2014 the most land undergone many changes occur in mixed garden, cropland, open land and shrub that converted turned into settlement with a total amounted to 11.12% of the total area, while the CO2-eq emissions in 2005-2009 increased approximately six times the emissions from 2000-2005 in the amount of 681 006.94 tons of CO2-eq per year.

The radiopharmaceutical kit production facilities usually use a clean room with an aseptic process. Therefore, it is very important to conduct research on clean room utilization for the production of radiopharmaceutical kits. The data was taken from radiopharmaceutical product that produced at Center for Radioisotope and Radiopharmaceutical Technology (PTRR), National Nuclear Energy Agency (BATAN) from 2015 to 2018. The results indicate the use of clean room depends on the drying duration of the radiopharmaceutical kit. Almost all radiopharmaceutical kits are dried for two days such as MIBI, MDP, Ethambutol, MAA, and Tetrofosmin kits. There are only two kits that are dried for one day, DTPA and EDTMP kits. The ratio of monitoring of drying temperatures during the drying process of DTPA kit (one day) and MDP kit (two days) shows that in 2015 the freeze dryer still showed maximum performance compared to the next three years. The optimal utilization of clean room is in 2015 as much as 100% while in 2016, 2017 and 2018 the average utilization of clean room is around 66%. The production process frequency is the lowest in June, followed by January and December due to the maintenance schedule. The longer the process of drying radiopharmaceutical kits, the longer the clean room facilities operate. The production process of radiopharmaceutical kits in 2015 is the most optimal.

Wood is an important element determining the quality of a product on furniture. The lack of knowledge of the furniture industry in this industry causes problems to choose a decision in determining the wood material to produce quality and quality furniture products. Development of a decision support system using the Analytichal Hierarchy Process method uses wood quality feasibility parameters consisting of five criteria, namely Physical Physical Properties, Mechanical Mechanical Properties of Wood, Wood Grade, Wood Age and Wood Substance from several samples. The results of this study were to produce a decision from the data to determine a decision, a decision support system for the purchase of wood materials for a furniture industry company using the Analytichal Hierarchy Process method. After testing, it can be concluded that the decision obtained is appropriate for use by staff and superiors and is ready to be implemented.

Cancer is one of the causes of death in Indonesia and even the world. Nuclear medicine techniques with radiopharmaceuticals and SPECT are one of the ways to treat cancer, but their use in Indonesia is not yet popular. Radiopharmaceuticals marked with radionuclide emitting beta (β) radiation are proven to be used for cancer therapy, one that has been developed in PTRR-BATAN is 90Y-EDTMP. Yttrium-90 is used in nuclear medicine by utilizing β radiation (E max 2.28 MeV). The β energy which is produced from the decay process of 90Y radionuclides to 90Zr can kill cancer cells. This study aimed to provide information about the substances biological effects so that preventive measures can be taken to protect humans. This study conducted evaluation of the 90Y-marked radiopharmaceutical (90Y produced from a 90Sr / 90Y generator which is 90Y-EDTMP) encompasses clearance test, pyrogen test, and dose safety test in experimental animals. The clearance test utilized mice, the pyrogen test utilized rabbits, and the dose safety test utilized mice. The results of the clearance test showed that 90Y-EDTMP compound which was excreted in 192 hour was 49.70% through urine and 14.59% through feces. The total excretion of 90Y-EDTMP within 192 hours was 64.57%. Based on the results of clearance tests with calculations, 90Y of 90Sr / 90Y generators in 90Y-EDTMP dosage form had 84.2 hours of half-life, 36.5 hours of an effective half-life and 52.7 hours of a residence time. Pyrogen test results showed pyrogen-free. The 90Y-EDTMP dose safety test showed that the dose is safe and not deadly. The development of 90Y-EDTMP is expected to be improved to produce radiopharmaceuticals for cancer therapy in order to make a real contribution in public health services.
