This research introduces ways of preparing the community to play a direct role in reducing the risk of earthquake and tsunami disasters. Nagari Matobe is a village located in South Sipora. This location is in an earthquake tsunami-prone area. The regional government has prepared Matobe village to be a disaster-resilient village. A previous survey from 2019-2020 showed that the community of Matobe village lacked knowledge of earthquakes, tsunamis, and disaster mitigation systems. This research aimed to improve preparation for earthquake and tsunami disasters by making the people of Matobe village resilient to disasters. The steps taken to improve community preparedness were: 1. An initial survey on community conditions, buildings, soil characteristics, and the community’s preparedness to face earthquakes and tsunamis; 2. The creation of a topographic map; 3. Education and training for elementary school students, with simulations, on the mechanism of earthquakes and tsunamis, on how to evacuate and prepare for evacuation, through stories using Doraemon, Nobita, and Dorami, comic characters from Japan; 4. Providing education and training on building materials under the 2002 Indonesian building planning standards and plans for earthquake-safe buildings following the 2016 earthquake-safe building structure standards; 5. Education and training to strengthen existing buildings; and 6. A proposal for a tsunami evacuation map and the location of evacuation signs. The community in Nagari Matobe was very cooperative and took an active role during the implementation of this research. The evaluation questionnaire distributed to elementary school students showed that the students were delighted and, on average, thought that the education and training in preparedness were beneficial. This education and training became an important reference for the community and government in developing Matobe village to become a disaster-resilient village.

Evaluation of interfacial Adhesion between concrete substrate and self-compacting concrete as a repair material Nawel Chibani; Ahmed Beroual

This paper focuses on using self-compacting concrete (SCC) as a material in the repair technique given the advantages it presents in the fresh state, namely: stability, homogeneity, and deformability, because it perfectly matches the shapes of the surfaces to be repaired. The interest is mainly focused on the evaluation of bond strength at the interface: Repair/Substrate. The assessment is made via a repair applied to a half-cylinder of the ordinary concrete substrate (OC), by using as a repair material two classes of self-compacting concrete (SCC) of different strength (30 and 40 MPa), the interface bond strength obtained in this case is compared to that of a half-cylinder (BO) repaired with vibrated concrete (OVC) used as a reference control concrete. The rheological properties of the (SCC) used were determined with the aid of the Slump-flow, L-Box, V funnel, and stability under sieve tests. Mechanical properties include compressive strength, and tensile strength. The test to assess the interface bond strength of the specimens is based on a splitting tensile test (indirect tensile). Finally, to determine the type of failure produced after the test. The results obtained showed that self-compacting concrete appears to be a very promising material in the repair and rehabilitation of concrete structures. SCC offers good interfacial bonding and therefore gives satisfactory interface bond strengths.

Memorizing Al-Quran is one of the most important acts of worship for Muslims. After memorizing some parts of the Al-Qur’an, the hafiz or Al-Qur’an’s memorizer is recommended to repeat or muraja’ah their memorization to strengthen it. This process is usually done in pairs by listening to each other’s memorization or testing by asking questions about Al-Quran. This study proposes a system that can help memorizers test their memorization independently without a partner. The system will perform a memorization test to support the user’s process of memorizing the Al-Quran. The system records and analyzes user data and uses it to personalize memorization testing from time to time. The system was made using the Group Decision Support System (GDSS) approach with the help of several Al-Quran memorizers as decision-makers. The GDSS algorithm used combines Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) and Weighted Geometric Mean to rank surahs based on provided user data. The evaluation was conducted with the help of human evaluators, and the evaluators showed 78% agreement with the system decision.

Environmental issues linked to climate change and global warming have been at the center stage of discussion all over the world. This is due to their magnitude and a broader scope of consequences. The catastrophic effects of greenhouse gases (GHGs) such as CO2, CO, water vapor, and ozone, coupled with other artificially induced chemicals like CFCs have shifted weather patterns across the globe, thereby threatening the environment unpleasantly. In Nigeria, the unprecedented utilization of fossil-based fuels as the main energy source for electricity, transportation, industrial, agricultural, and domestic purposes is one of the contributory factors of climate change. As a result, air pollution, land spills by oil, and increasing heatwaves negatively impacted the ecosystem by intimidating the environment, counteracting biodiversity, decelerating the economy, and provoking human comfort while simultaneously antagonizing socio-economic growth and sustainable development. Recently, the abrupt seizure of rainfall in northern Nigeria left many farmlands burning while many other places where been wiped out by heavy flooding. These scenarios have heightened food shortage, economic hardship and rendered thousands homeless. Thus, the government needs to intensify the campaign for afforestation by planting many trees to support green conservation of biodiversity and unleash the huge potentials of renewable energy resources in the country, as the plausible options to remediate the lingering energy failure and ravaging effects of climate changes. Therefore, this short review of communications X-rayed some recent devasting incidences caused by climate change, its impacts on various sectors, and the need to explore renewable energy resources in the country.

Physical Characteristics Of The Krueng Seunagan Watershed And River Storage Capacity Against Peak Discharge Afriadi Ihsan; Muhammad Rusdi; Hairul Basri

Peak discharge information is indispensable for flood control planning by taking into account the physiographic factors of the watershed. Flood occurs because the capacity of the watershed and river channels is smaller than the flood discharge. One of the causes of rivers' reduced flood flow capacity is vegetation cover and land use that cannot store rainfall. Thus, this paper aims to determine the peak discharge from the watershed's physical characteristics and land-use changes by comparing the river storage capacity in the Krueng Seunagan watershed. The rational method is used to calculate the peak discharge. Some of the data used in this study are the shapefile map provided by Geospatial Information Agency, land use, rainfall, soil types, and Landsat 8 OLI/TIRS digital imagery. Analysis of the physical characteristics of the watershed consists of morphology and morphometry. Land use in the area of the Krueng Seunagan watershed increased the peak discharge during the observation year (2003-2017). Besides the land-use factor, discharge is also influenced by high rainfall intensity and runoff coefficient obtained from land use analysis. In the Krueng Seunagan watershed area, the C value obtained was 0.0505 – 0.0720, indicating that the Krueng Seunagan watershed area was classified as good or harmless. The river flow density of 0.53 belongs to the medium category. The river flow increases and decreases in the flood water level, which is neither too fast nor too slow. The roundness index of the Seunagan watershed of 1.0004 indicates that the basins are widened or circular and, consequently, the rate and volume of surface runoff are fast. Krueng Seunagan watershed runoff coefficient increased by 42.51% and rainfall intensity by 37.05%, while discharge increased by 95.31%. The discharge capacity that the Krueng Seunagan River Basin can accommodate from the measurement results in the downstream watershed is 158.47 m3/sec. While the peak discharge using the rational method gets a value that varies in each year of observation from (2003-2017). The peak discharge value in 2003 amounted to 183.52 m3/sec, and the highest in 2017 amounted to 358.44 m3/sec. This shows that the river holding capacity in the Krueng Seunagan watershed will not accept the amount of peak discharge, and consequently, the flood will always occur.

The Determination of Kesongo Mud Volcano System Zone Using Seismic Interval Velocity at Potential Overpressure in The Tawun Formation, “F” Field, NE Java Basin Muhammad Burhannudinnur; Wildan Tri Koesmawardani

The Mud Volcano System (SMV) is an interesting topic, especially the relatively shallow oil and gas basin in North East Java. The Tawun Formation is an alternating layer of claystone that is quite thick. It has been confirmed in several oil and gas fields as a potential layer of a mud volcano system, specifically the Kesongo Mud Volcano System. The existence of this system is a challenge to further exploration; therefore, zoning is essential. The data used in this research were interval velocity cubes which were re-picked in each of the two bin sizes (2x25m) as the primary data. The well and velocity data were performed to determine the deviation from the Normal Compaction Trend (NCT). Furthermore, the seismic interval was confirmed with drilling data such as mud log and mud weight. The value of preliminary pore pressure was also derived from interval velocity using Eaton Equation which is confirmed by mud weight data. The Zoning of the Mud Volcano System was carried out via a depth slice at 3D seismic intervals. The results showed that the Tawun Formation has a Mud Volcano System prone zone at a depth of 204 m and decreases in geometry as the depth increases. Meanwhile, the OP-1 zone was the safest zone for exploration, followed by OP-2 but requires passage through the Kesongo Mud Volcano System zone of 1000 m thickness.
