  • Hexacopter Drones for Fertilizer Sowing in the Agricultural Sector Using
           the Global Positioning System (GPS)

    • Authors: Satyo Nuryadi , Rodhiyah, Bayu Ari Pratama Pratama , Zulkhairi

      Abstract: Indonesian agricultural products are one of the highest-yielding agricultural commodities on the Asian continent. Farmers are still reliant on a manual method to agricultural land care and management, one of which is the application of fertilizer to agricultural land. As a result, with the help of an unmanned aerial vehicle (UAV) or a robot flying drone, a system or fertilizer sowing equipment is utilized on plants. The results of this study led to the creation of a hexacopter drone equipped with fertilizer-based sensors and GPS. Hexacopter refers to a quadcopter having only four rotors. Drone rides are paired with tank-shaped sower actuators and fertilizer spraying as a container and fertilizer sowing method. Using GPS sensor block m8n, which serves as a satellite signal receiver and is converted to a position point in the form of longitude and latitude values, the vehicle can travel to fertilize by following the route of the coordinate point that has been identified in the agricultural land region. The Pixhawk 2.4.8 flight control system, which uses automatic or autonomous controls, can run smoothly, allowing the ride to automatically seed the track. The Lippo 2300mAh 4s battery has a maximum ride load lifting capability of 500 grams of fertilizer and a fertilizing height of three meters.

  • Distributed Database Implementation in Point of Sale System with Method
           Synchronous Replication

    • Authors: Sri Wulandari, Galuh Son Adji
      First page: 47
      Abstract: This SBS Endang Buah is a trading agency that sells various kinds of products fruit. Initially SBS Endang Buah only had one shop with increase in customers then open a branch store to deal with customers which increases. But data that is not distributed quickly result in data delays and make it difficult for the agency to manage sales data at branch stores and central stores. Therefore all data from branches and central stores must be distributed to each other and a base system is made distributed data on the sales system to make it easier for the agency processing sales data. And remembering these data is very important, of course requires data backup to anticipate data loss. Process database distribution will be created in real-time using replication synchronous. Where the master database residing in the central store will be replicated to the branch store slave database and vice versa, replication is carried out in both directions, so that data delays for processing sales data can be resolved as well as with the existence of two databases can anticipate data loss from things technical and non-technical.

      Abstract: The concept of "Green" is evolving with new innovations and techniques to protect environmental sustainability, embodied by corporate social responsibility, green manufacturing, waste reduction, recycling and manufacturing of sustainable supply chains and environmentally friendly supply chains. To reduce the use of plastic packaging, the industrial world is turning to green packaging. The eco-friendly packaging that was the subject of the study was a cellulose-based polymer made from cellulose, a major component in plant tissue. Coffee pulp has a high hydrated cellulose microfibrils with a unique morphology using certain chemical treatments. The content of this cellulose can be used as environmentally friendly packaging paper that will be used as packaging of processed coffee products. The method used in this study is by chemical means to remove the lignin content on the coffee skin as well as mechanical methods in the manufacturing process. In this study conducted four (4) experimental scenarios to produce a strong coffee skin packaging and have smooth fiber. From the experiment it was obtained that the packaging with a coffee skin proportion of 33.33% and 66.67% used paper waste had the highest tensile strength with a maximum load that could be held 94.2183 N and a maximum length increase of 11.0262 mm due to finer and denser scrap paper waste fibers binding together to fill the gaps of used paper fibers that had hollowed out adhesive. This ratio also shows good resistance when made into coffee product packaging so that the packaging used becomes environmentally friendly packaging by utilizing coffee waste itself, to produce pulp from coffee skin which is further used as raw material for making coffee packaging.

    • Authors: Muhammad Aldin Yusfan, Asep Adang Supriyadi , Sukendra Martha, Rudi Agus Gumilang Gultom, Sri Kartika Sakti
      First page: 56
      Abstract: The global phenomenon in the Industrial Revolution 4.0 era is currently hitting Indonesia. Many information floods the public every minute with various content spread across multiple media. This information for a country can be a powerful weapon as a form of intelligence product to prepare a national defense strategy. The demands of an increasingly fast-paced era make GEOINT needed to obtain information quickly, accurately and integrate synthesis and analysis. Therefore, this study was conducted to identify the development of GEOINT in Indonesia and its application in overcoming information overload in the present. This study uses the library method by collecting references relevant to the research problem from various sources. The study results indicate that the overload of information from multiple increasingly sophisticated media due to technological developments has made GEOINT's information sources richer. GEOINT in Indonesia continues to optimize accuracy and speed in geospatial analysis to avoid losing to the rate of data sources that continue to increase, both from human resources, hardware, software, and access to information available according to Indonesia's needs. GEOINT as a national defense strategy can be carried out as a form of effective information collection and can protect confidential information. GEOINT will become increasingly valuable in both military and non-military management over the next few years.

      First page: 74
      Abstract: The emergence of peri-urban areas as a transition zone between villages and cities has been influenced by the increasing flow of urbanization. Peri-urban is a dynamically developing suburban area with a mix of rural and urban characteristics. This mixture of characters can be classified from land use patterns, demographic characteristics, economy, and availability of public infrastructure services. On the other hand, the impact of urbanization in urban areas provides positive things through economic growth that supports the sustainability of people in urban areas. The city of Yogyakarta is a growth center in the Special Region of Yogyakarta consisting of 14 sub-districts with significant operations in the trade and service sector. The rapid growth of the city of Yogyakarta has triggered the development of the surrounding area which is directly adjacent to several sub-districts in Sleman Regency. This study aims to examine the typology and development of Yogyakarta City and its surroundings in 2015-2019 with the research area being 20 sub-districts in Yogyakarta City and parts of Sleman Regency. The peri-urban zone typological study employs descriptive geographic analysis, overlays, and scoring. According to a series of analyses, there were developments and changes in the peri-urban typology in Yogyakarta area and its environs from 2015 to 2019, which were turned into urban areas in terms of physical, social, and economic factors.

  • Syncronize Data Using MapReduceModel Programming

    • Authors: Murti Retnowo
      First page: 82
      Abstract: Research in the processing of the data shows that the larger data increasingly requires a longer time. Processing huge amounts of data on a single computer has limitations that can be overcome by parallel processing. This study utilized the MapReduce programming model data synchronization by duplicating the data from database client to database server. MapReduce is a programming model that was developed to speed up the processing of large data. MapReduce model application on the training process performed on data sharing that is adapted to number of sub-process (thread) and data entry to database server and displays data from data synchronization. The experiments were performed using data of 1,000, 10,000, 100,000 and 1,000,000 of data, and use the thread as much as 1, 5, 10, 15, 20 and 25 threads. The results showed that the use of MapReduce programming model can result in a faster time, but time to create many thread that many require a longer time. The results of the use of MapReduce programming model can provide time efficiency in synchronizing data both on a single database or a distributed database.
