    Authors: Bella Hardiyana ; Shinobu Hasegawa

    DOI: https://doi.org/10.37934/araset.31.1.355364

    Abstract

    Angklung is a traditional musical instrument from West Java, Indonesia. To play a song using this instrument can only be played in groups. The size of the musical instrument is quite large and prone to damage if carried anywhere, making it challenging to practice except in schools or music clubs. Since the pandemic, it has become increasingly difficult for students to practice angklung due to the limitations of face-to-face learning. This study aims to make it easier for students to practice and play angklung. The system is based on online multiplayer games so that students can learn and play angklung with more fun, and players can play anywhere. Players can use the mobile version of the angklung application as a substitute for the angklung instrument. Players can perform a duet with other players in playing the same song. The results of the player’s performance will be displayed as scores and stored in the database. Besides that, a real-time feedback function is always displayed for each note played. To distinguish individual players and/or notes, we use vibration sensor technology installed in each mobile application or signal processing, and the system will recognise them properly. We propose a Short-time Fourier Transform (STFT) algorithm as a scoring system and realtime-feedback performance. We use class diagrams to describe the whole application system and describe the functionality of the system in detail. We collect some research related to angklung and technology. Currently, there is a little study that could answer all the problems of learning and training angklung. The results of this study in the form of a system design are the initial research stage and are used for the following research phase. In conclusion, the design of this study can solve the existing problems so that the system will make it easier for students to practice and play angklung.

    DOI: https://doi.org/10.37934/araset.41.2.152163

    Abstract

    Water infiltration in the soil is an essential topic for investigation because soil fully saturated with water forms standing water that leads to flooding on top of the soil. Soil investigation is vital for agricultural study due to the necessity to know soil carrying capacity in holding water, field capacity, and also the soil temperature for biological activities and chemical reactions. However, human urbanization and expansion into previously unexplored soil areas could lead to unnecessary environmental stress, such as floods. Floodwater forms when the rainfall intensity exceeds soil water infiltration. The flood event is crucial since it affects the human livelihood and facility damages. Therefore, a good understanding of soil hydraulic water infiltration helps better understanding the cause of flood occurrence. The current study examines the soil series in Terengganu state with its soil properties concerning the soil water characteristics curve, which indicates the soil’s ability to absorb and allow water movement in the ground. The equation used was the improved Richards’ equation that can be applied to examine the standing water or floodwater impacts on water infiltration. Also, the unsaturated soil moisture movement conditions can be investigated. The simulation equation verifies with benchmark datasets that was solved on Richards’ equation using a different numerical method. The twelve-soil series of Terengganu state subjected to water infiltration study subjected to flooded conditions, by exposing the soil to the highest rainfall identified in the history of Kuala Terengganu from 1985 to early 2023. The results reveal Jambu, Rhu Tapai and Rudua soil series’ water infiltration rate was greater than the rainfall intensity, whereas other soil series could not accommodate the rainfall intensity. Thus, other soil series areas will likely encounter flooded conditions when exposed to heavy rainfall, as has occurred in history.

    Author: Risti Puspita Sari Hunowu

    DOI: 10.34010/ARTIC.2019.4.2418.167-176

    Abstract

    This research is aimed at studying the Hunto Sultan Amay Mosque located in Gorontalo City. Hunto Sultan Amay Mosque is the oldest mosque in the city of Gorontalo The Hunto Sultan Amay Mosque was built as proof of Sultan Amay’s love for a daughter and is a representation of Islam in Gorontalo. Researchers will investigate the visual form of the Hunto Sultan Amay Mosque which was originally like an ancient mosque in the archipelago. can be seen from the shape of the roof which initially used an overlapping roof and then converted into a dome as well as mosques in the world, we can be sure the Hunto Sultan Amay Mosque uses a dome roof after the arrival of Dutch Colonial. The researcher used a qualitative method by observing the existing form in detail from the building of the mosque with an aesthetic approach, reviewing objects and selecting the selected ornament giving a classification of the shapes, so that the section became a reference for the author as research material.Based on the analysis of this thesis, the form of the Hunto Sultan Amay mosque as well as the mosques located in the archipelago and the existence of ornaments in the Hunto Sultan Amay Mosque as a decorative structure support the grandeur of a mosque. On the other hand, Hunto Mosque ornaments reveal a teaching. The form of a teaching is manifested in the form of motives and does not depict living beings in a realist or naturalist manner. The decorative forms of the Hunto Sultan Sultan Mosque in general tend to lead to a form of flora, geometric ornaments, and ornament of calligraphy dominated by the distinctive colors of Islam, namely gold, white, red, yellow and green. © The Author(s) 2018.

  • Experimental Study of Dam Break Flow Generated by The Flap Gate in Horizontal Channel

    Experimental Study of Dam Break Flow Generated by The Flap Gate in Horizontal Channel

    Authors: Vitta Pratiwi ; Muhammad Syahril Badri Kusuma ; Hadi Kardhana ; Mohammad Farid

    DOI: 10.21660/2020.75.16098

    Abstract

    The risk of dam break failure become one of the most important issues to decide the feasibility of reservoir and dam development in Indonesia. This paper presents an experimental work result of a dam break flow through a single oblique obstruction in a straight rectangular channel. The dam break flow was generated by a sudden swing of a flap gate set on the contraction join of a horizontal reservoir and a horizontal channel. The initial condition of the dam break flow is set up based on the water height in this reservoir. A spatial temporal measurement of depth and velocity of the generated dam-break flow was conducted around the obstruction. The flow depth was measured using an ultrasonic-based sensor supported by a GPRS communication system, and the flow velocity was measured using a high-speed type current meter. Less correlation between the measured depth and velocity flow in the first of three seconds after the flow generation, where the flow has a high intensity of turbulent, was observed due to the limitation of data acquisition capacity. Compared to Noel’s experimental works where the dam-break mechanism is simulated using an uplift gate, the flow depth and velocity profiles of the current experimental work have a good agreement in its pattern and in less agreement in its magnitude. Meanwhile, compared to Noel’s numerical model result, it has fewer agreement results. These differences might be occurred due to the influences of differences dam break mechanism and data acquisition system. © 2020, Int. J. of GEOMATE.
