Abstract

An audio recorder is one of the multimedia content that is often found at the crime scene and is used as evidence in the trial process. Audio recorders that can be made as legal evidence in court must follow the rules and audio forensic standards that apply in the process of obtaining the evidence, this is because audio digital evidence is very easy to manipulate. The forensic audio investigation process requires a framework that can be used as a reference in the investigation process. However, at present, the developing audio forensic focus more on analyzing audio forensic techniques and does not provide more specific stages in handling forensic audio from the scene of the case to the trial process. This research focuses on developing the audio forensic framework by implementing the Systems Development Life Cycle (SDLC) in the process of developing the forensic audio framework. Systems Development Life Cycle (SDLC) has stages of planning, analysis, design, implementation, and maintenance that are often used as references in the process of making and developing systems. In other words, the implementation of this method will enable researchers to develop an audio forensic framework that can be used as a standard in conducting the forensic audio investigation process.Keywords—Audio Recorder, Audio Forensics, Framework, SDLCDOI : 10.5281/zenodo.2528444

Abstract

The problem of people's welfare is a problem that must be faced by developing countries such as Indonesia. Many indicators affect the level of people's welfare, such as population, education, levels and patterns of consumption, poverty, housing, and the environment. To make it easier in preparing plans or making decisions on issues of people's welfare, the government needs data and information regarding the level of people's welfare. Therefore, determining the level of people's welfare needs to be done.This study is intended to produce information on clustering districts/cities in Southeast Sulawesi Province based on indicators of people's welfare using the K-Means algorithm. The process of determining clusters consists of three processes i.e. Process of Collecting Datasets, Process of Clustering, and Process of Cluster Interpretation.The data used are data on people's welfare indicators from 12 districts/cities in Southeast Sulawesi for 2014. The data consists of seven variables, i.e. the Number of Health Facilities, Life Expectancy, the Projected Total Population, the Percentage of Non-Poor People, the Number of Administrative Regions, the Average Length of School, and Spending Per Capita. Based on the results of cluster analysis, it was found that the number of cluster members with low, medium, and high welfare indicators are 3, 6, and 3, respectively.Keywords—K-Means Algorithm, Cluster Analysis, Social WelfareDOI : 10.5281/zenodo.2528154

Abstract

Nowadays, we can find Lamongan Restaurants wherever we are. Almost every street there is one Lamongan Restaurant. One of these types of UMKM is so popular among the public. This happened because the food that offered was acceptable and became a favorite for the public, as well as what happened in Bangka Belitung Province. However, most UMKM still uses manual methods for bookkeeping and transactions. Problems arise when many customers come to place to order, as well as those who want to make payments must wait for the manual calculation. Besides, manual bookkeeping can still cause errors in the calculation. To solve this problem, an integrated management system is proposed throughout the Province of Bangka Belitung. That way, every UMKM can easily do bookkeeping and transactions, besides that the government can also easily to monitor, record, and access the information reports from UMKM. This study uses a prototype development model. The results are the implementation of the integrated management system for Lamongan Restaurants in Bangka Belitung province based on the web and Android.Keywords—Management Information System, Integration, UMKM Lamongan Restaurant, Android, Web ServerDOI: 10.5281/zenodo.2010359

Abstract

Surf zone is the most important area in the analysis of the coastal process because in that area three waves are no longer stable due to the energy lost after the wave breaks so that high turbulence occurs which causes the sediment transport process. The purpose of this research was to determine the width of the surf zone during high tide and low tide on the coast of Makassar City starting from the estuary of the Jeneberang River to the estuary of the Tallo River. Data analysis technique used in the form of wind direction and velocity analysis use the application surfer, fortranC++and GIS, effective fetch analysis, wave forecasting, and breaking wave analysis then measured the width of the surf zone using the bathymetry map of the research site. The results of this research are the average width of the surf zone in the research site affected by the tides where the widest average surf zone width occurs at low tide with a width of 618 meters and the narrowest average width of the surf zone occurs when the tide is 35 meters wide.Keywords—Coastal Area, Tides, Wide Surf ZoneDOI : 10.5281/zenodo.1911853

Abstract

The Quick Response Code technology (QR Code) is a type of matrix Code developed by Denso Corporation, with the aim of being a Code of translators at high speed. In its application QR Code can use the standard method and Euclidean Distance method on the process of reading. The benchmark in this discussion is whether there is a difference between Standard method and Euclidean Distance method on QR Code technology by looking at estimated time and accuracy after decoding data and information.The method used is qualitative research method with the type of comparative research. Based on the results of the study, it can be seen the comparison of time estimation, the Standard method has a shorter process time than Euclidean Distance, because of the Standard method using Library Zxing. Library Zxing is an open source library that works for processing various types of 1 dimensional and 2-dimensional barcodes that can shorten the QR Code reading compared to Euclidean Distance. From the level of accuracy, both Standard methods and Euclidean Distance methods have almost the same accuracy level that is at the time of reading QR Code the result is the same with plaintext.Keywords—Comparison, Euclidean Distance, QR Code DOI: 10.5281/zenodo.1610994
