Abstract

In this paper, we report the benchmarking results of Hyperledger, a Distributed Ledger, which is the derivation Blockchain Technology. Method to evaluate Hyperledger in a limited infrastructure is developed. The measured infrastructure consists of 8 nodes with a load of up to 20000 transactions/second.. The benchmarking of Hyperledger shows better than a database system in a high workload scenario. We found that the maximum size data volume in one transaction on the Hyperledger network is around ten (10) times of MySQL. Also, the time spent on processing a single transaction in the blockchain network is 80-200 times faster than MySQL. This initial analysis can provide an overview for practitioners in making decisions about the adoption of blockchain technology in their IT systems.

Abstract

Liquefied Petroleum Gas (LPG) is a diversion program undertaken by the government and become a modern household items today. The risk of the use of LPG is leakage of gas tube or gas hose. Gas leakage can couse explosion or fire resulting in many deaths and injuries. Governments have to disseminate the home safety of LPG and train how to mitigate household accident. This work aimed to minimize the possibility of fire and created a tool that is able to detect leakage of LPG  using gas sensor and Arduino Uno. We create a mechanical design diagram as a model that illustrates the relationships between sub-systems. When the sensor detects the LPG gas, the system activates the relay and indicator lights. In addition, this tool can send SMS in case of leakage of gas, so that action can be done quickly to stop the gas flow.

Abstract

Apartment is a building block which is divided into a number of spaces or units that are marketed on an intermediary or leased basis. Besides the location of the apartment is usually in the middle of the city close to various centers of activity (business,entertainment, health, education). So customers must come directly to the location of the apartment and compare one apartment with another apartment. This makes it difficult for many customers to make decisions in determining the choice of apartment in bekasi. Therefore this report uses the waterfall method which includes the analysis phase, the design phase, the implementation phase, the testing phase, the maintenance phase to complete the apartment selection.this study aims to design and build a decisionsupport system for apartment selection recommendations the reason that customers no longer need to come to the apartment one by one to ask the price, type, facilities with the system made easier to find an apartment as desired.The system implements by determining the criteria related to apartment search in bekasi which results in the customer being able to choose an apartment according to their desires that can be viewed based on the location of the apartment in bekasi.

Abstract

Extracurricular activities are part of the internal learning process of schools as an effort to channel talent as a driver of fulfillment and student development. Among the extracurricular activities at school are (1) scouts, (2) Paskibraka, (3) Red Cross, (4) School security forces, (5) Nature lovers, (6) School health, (7) Scientific Youth, (7) 8) Sports, and (9) Arts. The choice of extracurricular interests is an important factor for students. The right choice will have an impact on improving the ability and skills of students themselves. For this reason, in this study the SMART method was implemented that could assist students in selecting extracurricular activities that they would like to do. The implementation of the SMART method is carried out by means of or through decision support information systems. The decision support information system development is using the waterfall method which has five stages, namely communication, planning, modeling, construction and deployment. The results of the development show that the resulting information system can run the SMART method correctly starting from charging the value of interest, weighting, utility, and gritting. These conditions can also be seen from the results of tests that show all components can be accepted or functionaly.

Abstract

Augmented Reality (AR) is a new technology in real world modeling in the form of virtual objects. Aggregated reality has been developed in many mobile platforms. The information raised by augmented reality is a representation of the real world through a reference image that is a reference. Modeling that emerges from a scan of static markers in the form, color and information that appears. This obstacle is a problem that is often faced by developers from augmented reality based applications. These constraints make the existing application of augmented reality less attractive and not interactive. While one of the objectives of making augmented reality based applications is the user interaction on the application. To reduce the weaknesses found in augmented reality, one of them is to use the Live texturing concept in modeling augmented reality. This concept is a new breakthrough in the field of augmented reality. the effect of using the Live-texturing concept will give an interactive impression that is more than static augmented reality. By applying live texturing technology to augmented reality, users can provide color and texture scratches that will have a direct / real time impact on the 3D model that is displayed.

Abstract

Keamanan dan kerahasiaan data merupakan salah satu aspek penting dari suatu informasi. Pentingnya nilai informasi pada setiap aspek dapat memungkinkan adanya usaha pemindah alihan atau pencurian informasi atau data oleh pihak yang tidak berwenang. Adapun salah satu teknik untuk mengamankan data dan informasi yaitu dengan menerapkan penggunaan teknik steganografi. Penelitian ini membandingkan dua metode pada steganografi yaitu Pixel Value Differencing (PVD) dan Modulus Function (MF) untuk mengetahui metode mana yang lebih baik dalam hal kualitas citra dan kapasitas penyimpanan pesan. Penelitian ini dikembangkan menggunakan bahasa pemrograman Phyton dengan citra yang diuji pada kedua metode adalah citra berformat PNG. Berdasarkan hasil pengujian yang dilakukan algoritma PVD menghasilkan kualitas citra yang lebih baik dari algoritma MF karena menghasilkan nilai Peak Signal to Noise Ratio (PSNR) dengan rata-rata lebih dari 40db dan algoritma PVD juga menghasilkan stego image yang lebih banyak dapat menampung pesan dibandingkan algoritma MF.

Abstract

Performance is a very important factor in determining success in assessing work quality. Good performance is the hope of all parties in an institution, including agricultural institutions. The Sukaraja Agricultural Extension Service Technical Unit (UPT BPP) always supports to improve the performance of extension workers in order to improve the quality of extension workers. Evaluation of broadcasting performance is carried out from the beginning of the activities carried out, starting from the preparation, implementation, evaluation and reporting. Evaluation of instructor performance at UPT BPP Sukaraja is carried out every three months and six months. So far, the evaluation is done manually, so it does not need to be done in a timely manner because of constrained inadequate labor. The method used in the evaluation study is the use of agricultural instructors using the Bayes method. The Bayes method is first performed by calculating the value of each criterion, total weighting, probability perriterian, calculating the total probability, calculating the threshold of each criterion and calculating the threshold value then comparing the total value with the threshold value of each criterion. The results of this method produce a good agriculture instructor ranking ranking, namely with initial Sdn with a total value of probability 31.38 and those requiring guidance are extension agents with Sjn and Dsm with a total probability of 24.13, and a total probability of 24.
