Abstract

Based on data from the Ministry of Health, the distribution ratio between health workers and patients in Indonesia is still not equal distributed. It influenced by the distribution of health human resources that are not in accordance with the ideal needs of health services. This results need to identify the profile of the availability of health human resources in Indonesia. In this study, an approach will be implemented to identify the profile of health human resources availability using K-Means Clustering with a combination of pillar algorithms in optimizing the selection of the initial cluster centroid. Chi-square analysis is used to determine the disparity in the needs of health human resources with the conditions of the availability of health human resources in the Central Java region. The data collection method used in this research is the observation method, while the scientific method used in this research is the K-Means Clustering method. The results showed that the application has been generated can dynamically determine the health human resource cluster based on the disparity category of health human resource availability in the Central Java region. In addition, the labeling of the Pillar K-Means cluster based on the Chi-square test has a high degree of accuracy, namely 80%.

At the school the computer network system was very adequate, this proved to be an adequate laboratory. In addition there are various departments in the school, one of which is a computer network engineering department. Vocational education is part of the education system that prepares graduates to have enough stock to be able to work in companies and master the experience of one field of work from many other occupations. In order to increase students' soft skills and hard skills knowledge in the industrial world later, one of them is knowledge in the use of Information and Communication Technology (ICT), especially in the understanding of making simple web. For this reason, understanding on the simple web can later be applied in the world of work or after graduating from vocational school. Then carried out community service activities at the Vocational High School (SMK) by providing knowledge theory and practice of mentoring directly to students for 3 days namely in making the web. Increased understanding in making the web is intended to improve the hard skills of the participants. The activity is intended to be able to add to the experience of knowledge about the simple web and motivate students to find out more about making web specifically the simple web. The results showed that the participants were very enthusiastic to follow, participants could recognize, create, use and manage dynamic web in the form of blogs and the trainees already had a dynamic web in the form of blogs. Keywords: Vocational High School, Simple Web, Blog.

Abstract

Noise decomposition on seismic volcanic data with wavelet using Daubechies wavelet decomposition on X and Y direction record data. Seismic volcanic data is in the form of broadband data, which broadband data has a wide frequency range so that it has a high enough noise level. So that when the noise decomposition process is carried out in selecting the decomposition of the noise it must be appropriate so that the information contained in it does not decompose, this is because the volcanic broadband seismic record data contains volcanic earthquake event information that has an amplitude at the same value as the amplitude of the noise. Therefore noise decomposition is done by implementing wavelet, that is by using Daubechies wavelet decomposition. The results show that Daubechies wavelet decomposition can break down noise properly without losing the information contained in the signal. The decomposition of noise uses Daubechies db 5 level 5 wavelet decomposition in detail. The results of the wavelet using wavelet decomposition obtained vulcanic earthquake events whose signal results showed conformity with volcanic earthquakes with T. Minakmi and wasserman's forms.

Abstract

Letusan Merapi 2010 mengakibatkan kerusakan alat pengamatan seismik yang terpasang disekitar gunung Merapi. Penelitian ini bertujuan untuk meneliti karakteristik gempa vulkanik gunung Merapi dari daerah di luar bahaya gunungapi (stasiunWanagama). Analisis dilakukan dengan melakukan proses dekomposisi wavelet untuk memisahkan even gempa vulkanik dan noise yang terekam selama kurun waktu letusan gunung Merapi 2010. Proses dekomposisi dilakukan dengan menggunakan wavelet Daubechies orde 5. Intrepretasi dilakukan dengan melihat karaktersitik sinyal gempa vulkanik dengan kandungan frekuensi sinyal hasil dekomposisi tersebut. Dari hasil penelitian ini diperoleh informasi event gempa vulkanik yang terjadi selama letusan Merapi 2010.ABSTRACTEruption of mount Merapi in 2010 has caused damaged the seismic observation stations installed around mount Merapi. This research aimed to investigate the characteristics of Mount Merapi is volcanic earthquakes of the outside of volcanoes danger area(Wanagama station). The analysis was conducted by wavelet decomposition process to separate the noise volcanic and seismic events were recorded during the period of the eruption of Mount Merapi, 2010. The decomposition process was done by using wavelet Daubechies order of 5. Theinterpretation was made by looking at the characteristics of volcanic seismic signals with frequency content of the signal decomposition. From the results, the research shows event of volcanic earthquakes that occurred during the 2010 eruption of Merapi.

Abstract

Peningkatan volume kendaraan bermotor di Indonesia mengakibatkan peningkatan kebutuhan bahan bakar fosil dan emisi gas buang. Kelompok alkohol memiliki tingkat viskositas yang rendah dan dapat dijadikan sebagai solusi peningkatan kebutuhan bahan bakar dan emisi gas buang. Akan tetapi penggunaan alkohol pada basis yang tinggi berdampak buruk bagi performa kendaraan. Minyak sawit terbukti dapat mengurangi peningkatan kebutuhan bahan bakar. Minyak sawit dipilih karena ketersediaan yang melimpah dan harga yang relatif murah. Penelitian ini bertujuan mengevaluasi sifat kimia dan sifat fisik biodiesel dengan kandungan minyak sawit yang bervariasi. Sifat kimia dan fisik yang dievaluasi adalah viskositas, titik nyala dan nilai kalor. Berdasarkan hasil pengujian yang dilakukan, semakin tinggi volume minyak sawit dalam biodiesel, terjadi peningkatan viskositas dan penurunan titik nayala dan nilai kalor. Biodiesel dengan kandungan minyak sawit 85% merupakan biodiesel dengan viskositas tertinggi serta nilai kalor dan titik nyala terendah.

Abstract

Each study program seeks to improve the quality of education and accreditation. One element that becomes the value of accreditation is students who graduate on time. The more active students, the more students will graduate on time. Thus, the head of the study program needs to make predictions of students who will be inactive in the next semester. To make predictions, we must determine what features are needed. This article is the result of feature selection research to predict the active status of students. The selection of features using seven features using the RandomForest package from R Studio. One feature as output is the active status of students and six features as input i.e; grade point (GP), grade point average (GPA), parent work, school majors, school category, and student hometown. The results of the selection of features show the strongest features to the weakest are; grade points (GP), grade point average (GPA), work of parents, majors of origin, schools of origin, and student hometown
