Abstract

An Data collection and processing has been carried out to compare the aftershock decay method which aims to determine the assumption of aftershock ending time, how much energy, fracture length and fracture velocity occurred on the island of Bali. Data processing using several methods, namely the Omori method, the Mogi method I, the Mogi II method, and the Utsu method. The data used is based on the BBMKG Region III Denpasar earthquake catalog book, that’s is case of the Buleleng earthquake on November 14 2019, the Jembrana earthquake on July 16 2019 and the South Kuta earthquake on March 19 2020. Based on the results of data processing, for the Buleleng earthquake case the method closest to the observations was the Mogi II method with the energy is 1012 joules, the fracture length is 1.186 m and the fracture speed is 29.78 m/s. As for the Jembrana and South Kuta earthquake cases, the results of the calculation of all methods have not come close to the observations. The magnitude of the energy, the length of the fracture and the fracture speed of the Jembrana earthquake is 3.562313 joules, 32.733 m, 327.330 m/s. Whereas for the South Kuta earthquake, the energy, fracture length and fracture velocity were 3.162317 joules, 125.890 m, 70.750 m/s

Abstract

The purpose of this study was to determine the characteristics of the Automatic Oximeter+, the effect of gender, age, activity, and distance in using the Automatic Oximeter+. In general, the use of oximeters in the community is still minimal, and their knowledge of oximeters is also minimal. While the oximeter tool circulating in the community is still common and checking heart rate and oxygen saturation is still done manually. To overcome this problem, the researchers created a tool using the MAX30100 sensor to measure heart rate and oxygen saturation, and used the Bluetooth HC-05 module to send the measured values to a smartphone. The method used in this study uses repeated experiments. The data obtained will be processed using the method by calculating the validity of the tool and using simple linear regression, to determine the effect between variables. It can be concluded that this Automatic Oximeter+ has a validity value for oxygen saturation of ±98% and for heart rate of ±95%. The distance limit between the Automatic Oximeter+ and the smartphone is ± 30 m in limited space. According to research, oxygen saturation is not affected by gender, age, and activity. However, heart rate is influenced by gender, age, and activity.

Abstract

Determination of the effective dose on the abdo pelvis and organs at risk has been carried out from the results of the CT Scan irradiation at Sanglah General Hospital.The study began by collecting secondary data from the results of an abdominal CT scan, namely the CTDIvol and DLP values. Then the data was grouped based on gender of 40 patients with an age range of 20-70 years. The value of the effective dose in the abdo pelvis is obtained by multiplying the DLP value and the conversion coefficient k. While the effective dose to organs at risk is obtained from the product of the CTDIvol and wt. The results of the effective dose in the abdo pelvis were obtained in the range of 4.596-6.738 mSv for male patients while for female patients it was 4.209-5.232 mSv. The results of the effective dose in the abdo pelvis are still at the threshold set by BAPETEN, which is 13.275 mSv, so the CT scan is still suitable for use. Average effective dose values for critical organs were 0.2882 mSv for the liver, 0.8646 mSv for the kidney, and 0.5764 mSv for the gonad. The highest dose was received by the gonads. This shows that the gonads are the organs that have the highest sensitivity in receiving radiation doses in the abdo pelvis

Abstract

This study is aimed to investigate the effect of Learning Cycle 7E model on the physics problem-solving abilities (PSA) of students. This study is an experimental research with a non-equivalent control group design. The population is all students of class X MIPA SMAN 3 Selong. The sampling technique was purposive sampling in which class X MIPA 4 class as the experimental class and X MIPA 1 as the control class. The experimental class was treated with Learning Cycle 7E model, while the control class was given a conventional learning. Before and after being treated, both classes were given a PSA test which amounted to 5 questions. The results of the initial and final PSA tests were analyzed for homogeneity and normality to conduct hypothesis testing. Hypothesis test analysis shows that  is rejected and  is accepted, so it can be concluded that there is an effect of the Learning Cycle 7E model on students' physics problem solving.

Abstract

This study aims to determine whether there is an influence of the constructivism model through experimental and demonstration methods on student learning outcomes on fluid material at SMA Negeri 1 Suralaga in the 2022/2023 academic year". This study uses an experimental method with a posttest-only control design, which only provides a post-test at the end of the treatment. The population in this study were all students of class XI IPA SMA Negeri 1 Suralaga. Meanwhile, the sample in this study was class IPA 1 as the experimental group and class XI IPA 2 as the control group. The two samples were randomly selected with either Cluster Random Sampling (Area Sampling). The experimental group was taught physics using the constructivism model through experimental and demonstration methods and the control group was taught physics using the conventional model. The research data were analyzed using a one-sided t-test. Based on the results of the study obtained tcount (2,73 ) > ttable (1,68 )   at a significant level  is received. So, it can be concluded that there is an influence of the constructivism model through experimental and demonstration methods on student learning outcomes on fluid material.

Abstract

A study entitled " The Effect of Sintering Temperature Variations on the Crystalline Structure of Bovine Bone Hydroxyapatite" has been carried out. The aim of this research is to understand how the sintering temperature influences the hydroxyapatite lattice parameters and to understand how the sintering temperature influences the volume and density of hydroxyapatite. The synthesis process begins with a calcination at 300 °C for one hour, followed by a sintering process with varying temperatures, namely 600 °C, 700 °C and 800 °C for samples A, B and C, respectively. To determine the hydroxyapatite content in the samples, then characterization using XRD was carried out. XRD results analysis was carried out using match3 and Rietica software. Identification results using match3 software obtained the presence of hydroxyapatite compounds and impurity compounds in the form of (Calcium trimagnesium carbonate huntite, Fluorine, Magnesium Hydrogensulfate Hydrate, Sassolite, Zemannite). The volume fraction of hydroxyapatite obtained in this study ranged from 68.6 – 82.8%. The higher the sintering temperature, the greater the volume fraction of hydroxyapatite. The Refinement results show that the higher the sintering temperature, the smaller the value of the lattice parameters in the direction of the a and c axes. Variations in sintering temperature also affect the resulting unit cell volume and density. The higher the sintering temperature, the smaller the unit cell volume, conversely the greater the unit cell density value.

Abstract

Clustering is an activity of grouping data into the same group based on similarity. The purpose of the study is to cluster and determine student cognitive learning outcomes characteristics. Cluster analysis was conducted on student cognitive learning outcomes using algorithms K-Means and DBSCAN. Both algorithms are appropriate to have been applied to the overlapping data such as student learning outcomes data. Also, their advantages are scaling large datasets and outliers. The data used in this study is student cognitive learning outcomes - final and mid-term exams grade X in physics subject. Applying the two proposed algorithms K-Means and DBSCAN, the best cluster algorithm to have been used for clustering analysis is K-Means which is based on the highest silhouette score of 0.43, while the silhouette score of DBSCAN is 0.39 respectively. Using the best cluster, the K-Means algorithm, found two types of clusters – cluster 1 consists of 132 students who have a high average score, and cluster 2 shows 183 students who have a low average score in both final and mid-term exams respectively. From the analysis results, most students still have low cognitive learning outcomes in physics subject.
