LoRa is a low power wide area network communication that has ability to transmit data in a long range with a low power. Lora Alliance has designed a network architecture that usually used, called LoRaWan. The implementation of LoRaWan itself has not meet the requirement of LoRa as one of the LPWAN protocol because it still depend on the internet in processing and displaying data. To meet the purpose of Low Power Wide Area Network (LPWAN) such as simple implementation, low cost, and simple architecture, this research using Simple LoRa Protocol (SLP) with Raspberry Pi 3b+ as the smart gateway. The module used is Dragino LoRa that work in 868 MHz with Spreading Factor 7 and Arduino UNO for the client. The architecture build used in this research implemented to a monitoring system. The system build only to access a Local Area Network. Result showed that the smart gateway could handle the LoRa communication and the monitoring information system together. It also showed that the system average throughput is 489 bit/s and has packet loss 26% at 1-meter distance.
LoRa是一种低功耗广域网通信，能够以低功耗远距离传输数据。Lora联盟设计了一种常用的网络架构，称为LoRaWan。由于LoRaWan在处理和显示数据方面仍然依赖于互联网，其实现本身还不能满足LoRa作为LPWAN协议之一的要求。为了满足低功耗广域网(Low Power Wide Area Network, LPWAN)实现简单、成本低、架构简单的目的，本研究采用简单LoRa协议(simple LoRa Protocol, SLP)，树莓派3b+作为智能网关。使用的模块是Dragino LoRa，工作在868 MHz，扩展因子7和Arduino UNO为客户端。本研究使用的体系结构构建实现为一个监控系统。本系统仅用于接入局域网。结果表明，该智能网关可以同时处理LoRa通信和监控信息系统。系统平均吞吐量为489 bit/s, 1米距离丢包率为26%。

In the research of watermarking algorithm, the Singular Value Decomposition (SVD) is widely use. It has the capability of maintaining the imperceptibility and robustness at a good level. However, the SVD has a high level of complexity in the process of decomposition and reconstruction. It split a host image into three matrices of U, S, and V. The S matrix contains with the singular value and it is used in the embedding and extraction processes. The other two matrices of U and V are orthogonal and it is used to reconstruct the watermarked image. This scheme can be simplified using a single matrix which is orthogonal and symmetrical to replace the use of matrices of SVD. This paper is proposed a watermarking algorithm using a Walsh matrix which is symmetric, orthogonal and contains signed integer value of 1 and -1. The Walsh matrix is used to transform the host image into Walsh coefficient and reconstruct the watermarked image using a simple equation. The experiment result shows that the proposed method has faster embedding and extraction time with average time of 0.3841 and 0.1854 second compared to the SVD with average time of 0.6235 and 0.2539 second. Meanwhile, the both method has same level of robustness and imperceptibility. The average PSNR value of the proposed method and SVD are 41.4991 and 41.6518 respectively while the average NC values are 0.9416 and 0.9428. The proposed method is able to shorten the processing time without reducing the imperceptibility and robustness.

Business Intelligence is a technology for collecting, transforming, and presenting data for analysis as a tool for supporting decision making. Business Intelligence using Data Warehouse, Multidimensional data, and Online Analytical Processing (OLAP) has proven to be useful for obtaining information and knowledge relevant to the business. Nowadays the development of the internet with Web 2.0 model is increasing the availability of data over the internet. Linked Open Data (LOD), Open Data, and Open Government Data is constantly growing, producing a large amount of valuable data in the form of semi-structured data, flexible and machine-readable. Data sharing on agricultural production is one of the requirements for the best of analysis of agricultural production, but most of the data is still in the format of 2/3-stars open data and does not yet have spatial data that facilitates analysis based on spatial dimensions. The emerging open data concept makes the data warehouse more dynamic and can accommodate external data. Spatiotemporal support in open data also enables a more sophisticated analysis of data with spatial queries. This research develops tools to integrate agricultural data originating from the Village and Rural Area Information Systems (SIDeKa) that has open distributed data, a service-oriented approach, and spatiotemporal data. This paper also describes the design of business intelligence and multidimensional data for analysis and decision-making tools that enable spatiotemporal and non-spatial based analysis. This paper also highlights the opportunities for scaling and sustaining the initiative.

Maze Chase is a game that has a maze background. In this game there are players who have the task, which is to take all the points in the labyrinth. In the Maze Chase game there is also an NPC (Non-Playable Character) that aims to chase players so that players cannot take all the points in the labyrinth. Players can be considered to have won the game is that all the points in the labyrinth have been taken by the player. The author implements the A* and RIBS path search algorithms for NPCs so that NPCs can chase players. That way we get the travel time comparison to the players on each path search algorithm. After testing the average travel time to NPC players with the A* algorithm faster 0.116196% than NPC with the RIBS algorithm.

The safety of workers and equipment in the power system can be done using a safety system. This system consists of several components that work based on certain algorithms that will work if the system experiences interference. One major disturbance that can harm the system and the workers in it is the arc of fire. This disturbance begins with a short circuit that has enough energy to produce arcs of fire and even to an explosion. Relay equipment and circuit breakers can be used to protect the system. While humans can use Personal Protective Equipment (PPE) as a safety. PPE is determined based on the energy level of the incident from the arc. One effort to reduce this energy is to reduce the time of occurrence of arcs. The time of the incident is very closely related to relay work time. Relay working time determines the circuit breaker (CB) termination when a short circuit occurs. The shorter the relay's working time, the arc will also be shorter. Improvising the relay work time must pay attention to coordination between relays so that no trip errors occur. For this reason, the Zone Selective Interlocking (ZSI) method will be used to maximize work time and relay coordination by dividing the system into several protection zones. This study takes the case of a 20 kV distribution system. A distribution system with a large amount of load will increase the potential for interference. Simulation results show that ZSI can reduce the time the arc arises and does not interfere with relay coordination.

In a furniture decorative laminate industry, boiler is an important component to produce steam for machinery operation. Thus, improving efficiency of boiler becomes crucial step to reduce the operational cost and to increase the productivity. In this study, we investigated the replacement of steam trap in a boiler system using orificebased steam trap. Based on the real operational data, we found that the modified steam traps installed in an impregnation machine line could increase the boiler efficiency and decrease the fuel consumption by 7.1%, reduce the treated water by 5.5%, and decrease the condensate water volume by 1.9%. These phenomena occurred because there are no steam losses thus the boiler will work efficiently leading to the reduction in the use of fuel and treated water. The cost calculation concluded that the replacement of steam traps contributes to 2 months pay back period, Net Present Value (NPV) of USD 57,457, and Internal Rate of Return (IRR) of 562%.

The massive spread of harmful content on the internet is hard to filter. Meanwhile, blacklist content filtering cannot keep up with the rapid growth of content creations. As a result, an extra protection layer is required to provide a safe internet for children. However, implementing a network or application firewall requires an expert’s knowledge and complicated maintenance. In this paper, we proposed a framework to automate internet protection by using whitelist packet filtering. We use the blockchain smart contract as the secure collaboration media to determine the filtering rules. Meanwhile, the SDN controller automates the packet filtering by installing the determined forwarding rules into the network switches. We evaluate the whitelist packet filtering by using Mininet for the network emulation and Ethereum Rinkeby networks for the smart contract implementation. The result shows that the proposed whitelist system can filter the packet without incurring significant latency. It supports fast content update with a maximum speed of ≈ 1200 valid contents per-minute by using a three-votes verification system.

In evaluating the student’s learning outcomes, essay exams were commonly used by teachers to measure the level of student’s understanding of the learning material. However assessing essay answers was more difficult in reality because it contained teacher’s subjectivity and required a longer correction time. In addition, detecting similarity in essay answers between students also required more teacher’s efforts. In previous studies, a prototype of essay answer assessment and plagiarism detection had been successfully created. However, the prototype display still needed an improvement based on the evaluation results given by biology teachers in East Java Province as the application users. The previous prototype also still carried the Latent Semantic Analysis (LSA) method which had several weaknesses. Therefore, this study aimed to produce prototypes that had better display and text similarity methods. The Generalized Latent Semantic Analysis (GLSA) method was chosen because it was able to cover the weaknesses of the LSA method. GLSA was able to detect sentences that had syntactic errors or missing common words. Based on the evaluation results, this study succeeded in producing a prototype with a better display value. The level of user satisfaction increased by 6.12%. In addition, the study succeeded in using the GLSA method as a substitute for LSA for creating better prototype essay assessment and automatic plagiarism detection.

However assessing essay answers was more difficult in reality because it contained teacher’s subjectivity and required a longer correction time. In addition, detecting similarity in essay answers between students also required more teacher’s efforts. In previous studies, a prototype of essay answer assessment and plagiarism detection had been successfully created. However, the prototype display still needed an improvement based on the evaluation results given by biology teachers in East Java Province as the application users. The previous prototype also still carried the Latent Semantic Analysis (LSA) method which had several weaknesses.
