Boron Neutron Capture Therapy (BNCT) on radial piercing beam port Kartini nuclear reactor by MCNPX simulation method has been done in the National Nuclear Energy Agency Yogyakarta. BNCT is a type of therapy alternative that uses nuclear reaction 10B (n, α) 7Li to produce 2.79 MeV total kinetic energy. To be eligible IAEA conducted a study of design improvements and variations on some parameters to optimum condition which are Ni-nat thickness of 1.75 cm as collimator wall, Al2S3 as thick as 29 cm as moderator, Al2O3 0.5 cm thick as filter, Pb and Bi thickness of 4 cm as the end of the gamma shield collimators and Bi thickness of 1.5 cm as the base gamma shield collimators. The total dose was accepted in the tumor tissue 900 × 10-4 Gy/s. Radiation dose on the tumor tissue is 50±3 Gy with time irradiation of 9 minutes and 10 seconds. That dose was given into skin tissue and healthy liver tissue consecutively (6.00±0.05) × 10-2 Gy and (10.00±0.05) × 10-2 Gy. It shows the dose received by healthy tissue is still within safe limits.

Empty oil palm bunches are the largest solid waste produced from the palm oil industry processing. In processing 1 ton of fresh palm oil bunches, 230 Kg of empty palm oil bunches will be produced. Based on previous research, it is known that oil palm empty fruit bunches waste is proven to have a large amount of organic mass such as cellulose, hemicellulose, lignin. Organic content as mentioned is rich in benefits so that it can be used as raw material for making daily needs products ranging from food to complementary products such as household appliances, clothing and so on. For this reason, a study was conducted on the content of oil palm empty bunches originating from waste at PT. Kharisma Alam Persada. The characterization process was carried out using the SNI method 0128911992. From the research carried out it was found that the cellulose, hemicellulose and lignin content were 55.75%; 28.93% and 15.32% respectively. So that it is possible to be used as raw material for processing other products.

Plastic waste is a significant environmental challenge, but its management is still not fully effective. Common methods such as garbage disposal, combustion, and recycling have their limitations, especially the release of harmful compounds during low-temperature plastic burning. Therefore, research continues to look for better solutions. One promising approach is pyrolysis, a process in which plastic molecules break down at high temperatures in an inert gas environment. Pyrolysis produces solid, liquid, and gas products, with liquids potentially functioning as biofuels after further repairs. The study discussed the influence of temperature and time on the pyrolysis of HDPE and PET plastics. The results showed that temperature is a critical factor, with a limited reaction temperature between 500 Â°C and 700 Â°C. Results of the pyrolyse process include tar/liquid and char/ solid residues. Strangely, 3 kg HDPE produce the highest amount of tar, about 973 ml, while 3 kg PET produce the least, about 89 ml. Overall, achieving a uniform heat distribution and optimal temperature is crucial to improving the efficiency and quality of the pirolysis product.

Emisi gas buang dipengaruhi oleh jenis bahan bakar dan jenis kendaraan yang digunakan, oleh karena itu untuk mengurangi kadar emisi gas buang dapat dilakukan dengan cara menyempurnakan pembakaran dan menambahkan catalytic converter pada knalpot kendaraan. Penelitian ini membuat alat catalytic converter dengan memvariasikan penggunaan material logam agar dapat mengetahui pengaruh emisi gas buang pada sepeda motor. Metode penelitian yang digunakan adalah jenis ekperimental. Variabel yang digunakan yakni stainless steel, tembaga, aluminium, dan fiberglass. Hasil pengujian pada rpm 3000 menunjukkan bahwa adanya penurunan kadar CO2 1,24%, dan juga HC sebesar 141,7 ppm CO2 3,1%, ini terjadi pada katalis tembaga. Pada katalis aluminium pada rpm yang sama terjadi penurunan kadar hc sebesar 143,7 ppm dan kadar CO turun sebesar 1,15% karbondioksida turun sebesar 2,9%. Pada katalis spongesteel pada rpm 3000 terjadi penurunan kadar CO sebanyak 1,49%, sedangkan untuk kadar HC terjadi penurunan 166,34 ppm dan karbondioksida turun 3,47%. Sedangkan untuk katalis fiberglass kadar co menurun sebesar 1,21% dan kandungan HC sebesar 154,4 ppm, dan kadar karbondioksida turun sebesar 3,04%. Exhaust Emissions Are Substances In The Form Of Gas Or In The Form Of Other Particulates Expelled Through The Exhaust And Is The Residual Result Of Fuel Combustion In The Combustion Chamber. Exhaust Emissions Are Influenced By Several Things, Including The Type Of Fuel Used, And The Type Of Vehicle Used And The Age Of The Machine. Therefore To Reduce The Levels Of Exhaust Emissions Can Be Done In Several Ways, Namely By Perfecting Combustion And Also By Adding A Catalytic Converter To The Exhaust Of The Vehicle. The purpose of this research is to make a catalytic converter with a variety of metals in order to determine the effect of exhaust emissions on motorcycles. The research method used is the type of experiment. Variables Used Are Stainless Steel, Copper, Aluminum, And Fiberglass. Based on the Emission Test, it can be concluded that the results of this study at 3000 rpm indicate that there is a decrease in CO2 levels of 1.24%, and also Hc by 141.7 ppm CO2 3.1%, this occurs in the copper catalyst. In the aluminum catalyst at the same Rpm there was a decrease in Hc content of 143.7 ppm and a decrease in co content of 1.15% carbon dioxide decreased by 2.9%. In Spongesteel Catalyst At 3000 Rpm there was a decrease in CO levels of 1.49%, while for HC levels there was a decrease of 166.34 ppm and carbon dioxide decreased by 3.47%. As for the Fiberglass Catalyst, the CO content decreased by 1.21% and the HC content was 154.4 ppm, and the carbon dioxide content decreased by 3.04%.

Sepeda motor merupakan alat transportasi yang digerakkan oleh mesin (motor). Jenis transportasi ini banyak digunakan karena harganya yang murah dan mudah digunakan. Sepeda motor umumnya menggunakan bahan bakar bensin. Motor bensin 4 langkah adalah motor bensin yang melakukan usaha atau kerja diperlukan 4 langkah gerakan piston dan 2 putaran poros engkol. Catalyst adalah salah satu teknologi yang digunakan untuk mereduksi gas buang CO menjadi CO2 dan HC menjadi H2O, pada saat dikeluarkan pada knalpot. Knalpot katalis B yang lebih bagus dalam mereduksi emisi gas CO disetiap rpm nya. Dan dengan menggunakan knalpot katalis C berhasil menyerap emisi gas buang HC yang signifikan pada rpm 3000 dan 5000. Penambahan katalis pada knalpot berhasil mereduksi kebisingan. Dari ketiga model variasi katalis yang divariasi, knalpot katalis B yang paling baik dalam mereduksi kebisingan. dikarena bentuk katalisnya yang dapat lebih baik menghambat aliran pembuangan pada knalpot karena itulah suara yang keluar jadi sedikit lebih senyap. A motorbike is a means of transportation that is driven by an engine (motor). This type of transportation is widely used because it is cheap and easy to use. Motorcycles generally run on gasoline. A 4-stroke gasoline engine is a gasoline engine that does work or work that takes 4 steps of piston movement and 2 rotations of the crankshaft. Catalyst is one of the technologies used to reduce CO exhaust gas to CO2 and HC to H2O when released in the exhaust. The catalyst B exhaust is better at reducing CO gas emissions at every rpm. And by using an exhaust catalyst C managed to absorb significant HC exhaust emissions at 3000 and 5000 rpm. The addition of a catalyst to the exhaust managed to reduce noise. Of the three models of varied catalyst variations, exhaust catalyst B is the best at reducing noise. because the shape of the catalyst can better inhibit the flow of exhaust in the exhaust, that's why the sound that comes out is a little quieter.
