Abstract

Biourine is urine taken from livestock, especially ruminants, which is fermented before being used. The purpose of this study was to determine the effective fermentation time and local microorganism concentration (MOL) of rice straw to produce the highest nitrogen content in bovine biourine. Biourine is obtained through the fermentation method and analysis of nitrogen levels using the Kjehdahl method. The fermentation treatment given to bioourine was for 10 and 15 days of treatment using 4 combinations of MOL concentrations of straw, cow urine and EM4 used. The results of the analysis of nitrogen levels in biourine fermented for 15 days were much higher than those fermented for 10 days. The total N levels in biourine fermentation for 15 consecutive days from K1, K2, K3 and K4 were 0.0828%, 0.1110%, 0.1074% and 0.0836%. It can be seen that the highest nitrogen content is at the second concentration with a combination of 50 grams of straw, 1000 mL of cow urine, and 5 mL of EM4. So that the use of the MOL concentration with a fermentation time of 15 days was able to increase total nitrogen levels significantly when compared to control urine which only contained 0.0399% nitrogen if done without fermentation

Abstract

This study aims to determine the hydrocarbon reservoir zones in the ABD-1, ABD-2 and ABD-3 fields which are analyzed using quantitative and qualitative analysis to determine reservoir properties involving gamma ray (GR) log data, neutron log (NPHI) and log density (RHOB). The stage of determining the hydrocarbon content using resistivity log data, NPHI log and RHOB log. Determination of reservoir zones of hydrocarbon reservoirs using resistivity log data analysis and NPHI log data. The quantitative analysis in this study calculates the value of shale volume (Vshale), porosity (Ф), resistivity (RW) and water saturation (SW). The research results obtained from quantitative analysis using the ABD-1 well at depths of 7422 ft -7426 ft, 7869 ft - 7924 ft, 8033 ft - 8100 ft are able to determine the percentage of hydrocarbons contained in the zone. For gas, the value of Sw is 0 – 35, oil has a value of Sw, which is 35 – 65, and water has a price, Sw, which is 65. These percentages cannot be used as a benchmark for the assumption of hydrocarbons containing oil and gas, because if the price of Sw is 35, it could be oil. or vice versa. If using qualitative analysis it is found that the reservoir zone at a depth of 7422 ft – 7426 ft is a gas-containing hydrocarbon. At depths of 7638 ft – 7730 ft are gaseous hydrocarbons. Reservoirs at a depth of 7422 ft – 7426 ft are water-containing hydrocarbons.

Abstract

Research on the utilization of Gold Nanoparticles (GNPs) has rapidly advanced in recent decades, particularly in the biomedical field for cancer detection and therapy. GNPs have unique characteristics, such as nanometer size, high chemical stability, modifiable optical properties, and good biocompatibility, making them ideal candidates for applications in nanomedicine. This literature reviews the utilization of GNPs in cancer detection through local surface plasmon resonance (LSPR)-based imaging techniques, signal enhancement in Raman spectroscopy, and the delivery of specific diagnostic agents. Additionally, in cancer therapy, GNPs are used for photothermal, photodynamic, and targeted drug delivery, which can enhance therapeutic efficacy and reduce side effects on healthy tissues. This literature review also covers the main challenges in the development of GNP-based technologies, including toxicity, in vivo stability, and production scalability. The results of this study indicate that GNPs have great potential for clinical application, although further research is needed to address technical and ethical constraints before they can be widely implemented in cancer treatment in humans

Abstract

This research examines the relationship between music and the laws of nature through the perspective of the philosophy of science and Islamic values. Using the literature review method, various classical and contemporary texts, including the Qur'an, Hadith, and the thoughts of scholars, are analysed to understand music as a reflection of the harmony of the cosmos. Science philosophy views music as a form of mathematical and physical patterns that describe the order of the universe. On the other hand, in Islam, music is associated with dimensions of spirituality and morality, which highlight the harmony between humans and nature. This research shows that both science philosophy and Islam emphasise the importance of the relationship between art, science and spirituality in understanding the universe. The findings expand cross-disciplinary understanding of the role of music in reflecting the beauty and order of nature, and open up opportunities for further study of the impact of music on human life from a scientific and spiritual perspective.

Abstract

Stand Up Comedy is one of the growing entertainment industries in Indonesia. The quality of the joke of the stand up comedian can be seen from the audience's response in the form of laughter and facial expressions. But it is very difficult to determine the audience's laughter level manually. Therefore, a tool is needed to measure the audience's laughter level more objectively. In this study, a machine learning model was designed and developed using a convolutional neural network to analyze the facial expressions of the stand-up comedian audience. The research stages include dataset collection, data preprocessing, model design, model training and model testing. The model was tested using artificial data from crowd emotion and live data from video crowd viewers. The results of this study show that the model can classify facial expressions in image and video data well. The model has an overall validation accuracy value of 72.42% with precision, recall, and F1-score values of 0.7341, 0.7309, and 0.7294, respectively, and a testing accuracy of 83.28% with precision, recall, and F1-score values of 0.8477, 0.8329, and 0.8297, respectively.
