Utilizing Digital Storytelling Structure for Developing an Electronic Traditional Game Gobak Sodor

Gobak Sodor is a traditional game that came from Indonesia. Gobak Sodor is also known as a different name in Indonesia and Malaysia, such as Panjang tangan in Riau-Sumatra, Asing in Makassar, Galah Asin in West Java, and Galah Panjang in Malaysia. Gobak Sodor is a game that is played in two groups and has a rule that one group must prevent the opponent through the line back to back. However, Indonesia's open area has gradually reduced so that people difficult to play gobak Sodor. The loss of open land for playing Gobak Sodor and game technology advances make children slowly forget the gobak sodor. In the present time, technology is common for people to support their daily life activities. One of technology implementation form is electronic game, where peoples can play without the limitation of time and space. The electronic game also give pleasure and fun as much as conventional game activities. With the form of electronic game, this research develop a game application which implements all of the gobak sodor rules. Where the players can play the gobak sodor using their mobile device and without the trouble to play on a field or open space. Using electronic game for playing Gobak Sodor gives people satisfaction, awareness. In the hope that this will preserves the traditional game Gobak Sodor. The survey found that 80% of people have an interest to play The Gobak Sodor game.

Floods and their problems: Land uses and soil types perspectives

The phenomenon of flooding that occurs in almost all regions of the earth causes loss of property and damage to public facilities and causes the loss of many human lives. There are many reports related to the causes of flooding with various solutions offered to overcome the flood problem. However, it seems that these efforts have not been able to eliminate the flood problem. Hydrologists have widely reported various factors that are the cause of flooding with an extensive scope. Therefore, this paper is limited to discussing flooding and its problems, specifically the river flood, from the perspective of land use and soil types. Changes in land use in a watershed can cause an increase in the runoff coefficient. Likewise, different types of soil have different abilities in passing water into the ground. Open land (without land cover) tends to be prone to erosion, reducing the soil’s infiltration capacity and increased surface runoff. Increasing the runoff coefficient will increase the peak discharge in a watershed. The decrease in the river capacity due to sediment can cause a river flood. To support this argument, a rainfall-runoff model, particularly the tank model, is also discussed, taking into account the various uses and types of soil in a watershed. Efforts to anticipate the river flood are also considered for formulating flood disaster control policies in a watershed.

Land Use Changes Analysis in Jakarta Bay Coastal Area Between 1998, 2008 and 2018

As the national capital and one of the largest cities in the world, environmental conditions and land use in Jakarta have changed a lot in the last twenty years. Economic growth and high population growth in Jakarta have resulted in massive development of infrastructure and residential areas in Jakarta. Economic growth and an increase in population are become problems, especially with the decreasing of green areas due to the development process carried out without paying attention to the surrounding environment. Environmental problems such as water pollution, land subsidence, coastal erosion and flooding often occur in the Jakarta area, especially in the coastal areas of North Jakarta. The research from 1998 to 2018 show that from the observations area of mangrove land cover has increased by 79 hectares during that period. The same trend applied on area of built and open land that increased by 292 hectares and 887 hectares respectively. Meanwhile, the area of land for vegetation, water bodies, and fishpond has decreased from 1998 to 2018 by 393 hectares, 797 hectares and 309 hectares respectively. Development and reclamation have changed land use in the Northern area of Jakarta. However, it is also necessary to pay attention to the impact of development on environmental and social conditions in the North Jakarta area.

Geomorphology and Prehistoric Settlements on a Volcanic Island: the Case of Ustica (Palermo, Italy)

This study represents the first attempt to combine the geomorphological characteristics of the island of Ustica with the human settlements that have been established during prehistory, with the purpose of reconstructing the interactions between communities and the natural environment from the Neolithic to the Middle Bronze Age (6th - 1st millennia B.C.). Ustica is a small island in the Southern Tyrrhenian Sea, visible but far (~55 km) from the northern coast of western Sicily. Its rugged volcanic nature, remodeled and enriched by the sea, offered to the first colonizers a wide repertoire of opportunities and challenges. This island can be treated as an ideal “laboratory” to understand how settlers, taking their first steps towards the foundation of organized communities, were able to seize opportunities or succumb to obstacles. The review of archaeological research until now carried out in Ustica, integrated with geomorphological data and other biogeographical indicators, offers a picture of the prehistory of Ustica in which human presence is continuous and distributed in various sites of the island characterized by different physiographic characteristics. There are phases dominated by the choice of naturally protected sites and phases in which settlements expands on open land, suitable for agricultural use. Where the archaeological evidence is scarce, the geomorphological peculiarities allow us to decipher the vocations and characters of a human settlement. The study leads to an open question: in the Middle Bronze Age, after about five thousand years of uninterrupted habitation of Ustica, which factors, geological, social, or other, induced the early communities to abandon the island, without returning there for about eight centuries, until the Hellenistic-Roman age?

Design of Autonomous Unmanned System for Aerial Operations From Underwater Platforms

Surveillance and reconnaissance play a very important role in military and civil aspects. They are the key factors in military tactics and in the event of civilian calamities. In case of naval warfare, the submarines which are operating under deep water are required to carry out open land mass surveillance in an efficient manner without reaching to the water surface nor revealing their presence and position. This research paper proposes the conceptualized design to develop an autonomous unmanned octocopter system which is capable of being launched from an underwater platform such as submarines, with the help of a tethered launching mechanism known as octopod, to carry out surveillance, reconnaissance and payload delivery. In this paper, we present a novel method for development of UAV with special application on aerial survey from underwater platforms. A variety of design options which are investigated from various trade studies to evaluate the performance along with design configuration to satisfy the specific requirements are also presented in this paper.

Monitoring of Land Use Suitability Based on Detail Urban Spatial Plan Data 2018-2038 (Case study: Gayungan District, Surabaya City)

Land use planning in an area will refer to the regulations that have been established by the City Planning Office of each region. This is because each region has the authority to plan spatial plans in their respective regions. The border area is an area whose land use can be influenced by two different regional regulations. This is because the border area is a special area located on the border between two regions, each of which has spatial planning regulations. Gayungan District is one of the sub-districts included in the Border Area between Surabaya City and Sidoarjo Regency. To prevent overlapping spatial regulations that may occur in Gayungan District, it is necessary to monitor the suitability of land use using geographic information system technology and remote sensing. The data used in this study are the 2019 Gayungan District RDTRK Map and very high resolution satellite imagery of Pleiades Surabaya City 2019. The method used is the Object Based Image Analysis (OBIA) method. The result of this research is the suitability of land use in Gayungan District. A land use can be said to be suitable if the existing land use is in accordance with the land use in the plan. Meanwhile, land use is said to be inappropriate if the existing land use is different from the planned spatial use. All land use classes in Gayungan District in 2019 had a higher percentage of unsuitable land than the percentage of suitable land. Each percentage of land is not suitable for each land use class, namely: water body class by 92.593%, road class by 78.035%, industrial class by 77.838%, defense class by 76.706%, green open space class by 69.736%, and residential class by 52,27%. So it can be said that the land use in Gayungan District in 2019 was not in accordance with the plans in the City Spatial Detail Plan Map for 2018-2038, but the land use could be appropriate in its designation for the future, because there is a possibility of development for residential class, industrial class, and defense class on open land that is still widely available.

Assessment of spatial changes of LULC dynamics, using multi temporal landsat data (case study: Lesti Sub Watershed, Malang Regency, Indonesia)

The research background is to present certain important observations about land change as one of the basis for decision making for water resources management in the sub-urban environment, taking into account field data and classification of satellite imagery to understand natural spatial change patterns. The Lesti sub-watershed, an area upstream of the Brantas River related to multi-functional activities, continues to develop in terms of infrastructure management, especially the river water discharge that enters the Sengguruh Reservoir which causes increased pressure on water and human needs for housing. The method is utilizing Landsat satellite imagery for the last 20 years is used to obtain an analysis of land use/land cover (called: LULC) changes to see the rate of change over the last 20 years. The land use classes used are agricultural land, surface vegetation, built-up areas, open land, and water bodies. Landsat satellite imagery data are classified and used to obtain LULC analysis in the area, to estimate and understand the rate of change over the last 20 years. The results showed that for 20 years, vegetation and open land experienced a considerable decline, while the value of built-up land increased from 0.79% to 13.26%.
