Abstract

Covid-19 has a major impact on human life, including the process of managing digital evidence. Management of digital evidence requires special handling that can store and maintain the integrity of digital evidence. The current problem is there is no concept of storing digital evidence that can be accessed online in wider accessibility. Online digital evidence management is proposed as a solution to solve this problem. This concept is in the form of an online digital evidence management system that can be accessed anywhere and anytime using MD5 and SHA1 hash functions in order to maintain the properties of digital evidence so that it can be legally accepted. The problems with digital evidence management require a Management System for Digital Evidence that is suitable for application in Digital Forensics Laboratory. This research had successfully implemented the concept of online chain of custody. It is expected, with the concept of Online Digital Evidence Management, this digital evidence control and all activities related to it can be maintained and well documented. Moreover, it can reach a wider area accessed anywhere and any time and reduce the spread of Covid-19.

Abstract

Poverty is one of the problems experienced by some developing countries, including Indonesia. There are many ways to mitigate poverty, for example, Indonesian government policy overcome this situation by Non-Cash Food Aid Program (BPNT). The electoral candidate for BPNT in the rural area is carried out by Poverty Reduction Team (SATGASKIN). To avoid uneven and untargeted assistance with the process, a system is capable for addressing the matter. The selection methods in this research were Naive Bayes and Simple additive weighting. The purpose of this research was to design and build an application that provided convenience to SATGASKIN in determining the eligibility of prospective beneficiaries and prioritizing beneficiaries. As a result of the study, the system can be used by SATGASKIN to help determining the recipients’ eligibility with 85% accuracy value, 85.71% Precision, and 92.31% Recall. Naive Bayes and Simple Additive Weighting (SAW) methods reached 100% according to the results by manual calculations.

Abstract

Metadata is information in a file which its contents are an explanation of the file. Metadata contains information about the contents of data for file management purposes. In various cases involving digital evidence, investigators can uncover a case through the metadata file. Problems that arise when file metadata has changed or deleted information, for example, the moment that a file is shared via social media. Basically, all of the shared files through social media will experience changes in metadata information. This study conducted detailed analysis of changes in metadata information and hex dump values to determine the changing characteristics of metadata files shared in social media. This research method applied a comparison table to see the details of changes in metadata values from all files and social media as research objects. The results of this study are expected to have contribution for forensic analysts to identify the shared metadata characteristics of files in social media. As a result, later, the source of shared files in social media will be known. Moreover, it is expected from these findings that forensic analysts can explore the social media used by the cybercrime perpetrators.

Abstract

The XYZ cooperation is a business entity dealing with savings and loans, building rental, convection, rice procurement and shops that are very concerned about the welfare of its members. The appraisal process for loan approval decision in the XYZ cooperative was still lack of assessment. It was based on the value of the members’ report cards which covers collateral, wealth, and behavior so that the funds were not often on the target. Moreover, the cooperative members were often careless in repayment process. The method in this research was Exponential Comparison Method. This method determined the priority order of alternative decisions with criteria. Those criteria in this research were: Report cards, BI Checking, Application Purpose, source of income, monthly income, installment period, completeness of files, guarantees, status, and the amount requested. As a result of applying this system and adding some new criteria, cooperation considers loan approval assessments in determining the eligible members. The results of functional testing by black-box method showed that the system ran as expected and the functions of the application ran properly.

Abstract

Website is a collection of online documents containing Web pages that are moored in a domain as a unique name. It can be accessed via the Internet so that existing information can be displayed and accessed by Web visitors. Web visitors tends to need websites with user interface which is easy to use, to interact (usability), or communicate in sharing information. There are basically some benchmarks that can be used to measure website usability, including (1) Learnability, easiness to learn; (2) Efficiency, user speed level; (3) memorability, easiness to remember; (4) Error and safety, low fault rate; and (6) Satisfaction, satisfied user. Moreover, there are several methods of evaluation of the website in this research, such as: (1) Thinking Aloud Method, (2) User Perfomance test, (3) Remote Usability Test, (4) Cooperative Evaluation, (5) Expert Review, (6) Heuristic Evaluation, (7) Cognitive Walkthrough, (8) Plurastic Walkthrough, (9) Field Observation, and (10) Interview and Focus group.   In addition, the selection of a questionnaire or sampling deployment method and designing interface method may also affect the outcome of the evaluation of the website.

Abstract

The level of rice productivity is influenced by several inhibiting factors, for example disease attack in rice plants. The slow and inappropriate treatment of rice plant can make the crop failure so that rice production and farmers' income decrease. The symptoms of rice disease are difficult to distinguish, especially in severe symptoms. Collaboration with other fields, especially computer science, is needed to classify diseases automatically so that the farmers can take action for plant treatment and the spread of disease can be controlled quickly. The classification of diseases based on images requires the best features/characteristics so that the disease can be classified. In this research, Deep Learning method, especially Convolutional Neural Network with EfficientNet B3 architecture, can extract features very well. In this research, the classification of brown spot and bacterial leaf disease by applying EfficientNet B3 with transfer learning reached 79.53% accuracy and 0.012 loss/error.

Abstract

Circular Number 05/SEK/STMIK-SN/IV/2020 in STMIK Sinar Nusantara Surakarta regulates implementation of learning, midterm exams, and even thesis / final exams. Hence, STMIK Sinar Nusantara took a policy for the implementation of synchronous learning and asynchronous learning. Synchronous learning (one time: teleconference, chatting) applies (1) Google Meeting by sinus.ac.id account, (2) Virtual meeting as Skype and Zoom, and (3) Discussion in Classroom. Meanwhile, asynchronous learning (time difference) uses (1) handouts, (2) tutorials, (3) videos, and (4) simple exercises. The purpose of this study was to determine the mechanisms in online learning (E-Learning) during Covid-19 Pandemic at STMIK Sinar Nusantara.  This research only focuses on Synchronous and Asynchronous E-learning mechanism at STMIK Sinar Nusantara in even semester of 2019/2020. This research was conducted using 49 lecturers as respondents. The research method was descriptive statistical analysis. The results of the study by sampling 49 respondents as lecturers in online learning during Covid-19 Pandemic at STMIK Sinar Nusantara can be concluded that Synchronous learning (Conference by Google Meet, Skype, Zoom, Youtube Live, Umeetme) reached 57% and those who did not apply Synchronous learning (no conference) reached 43%. Meanwhile, the results of analysis in Asynchronous learning (handouts, tutorials, exercises / discussions, and videos) reached 88% and those who did not apply Asynchronous learning reached 12%.
