Abstract

A lava flood disaster is a volcanic hazard that often occurs when heavy rains are happening at the top of a volcano. This flood carries volcanic material from upstream to downstream of the river, affecting populous areas located quite far from the volcano peak. Therefore, an advanced early warning system of cold lava floods is inarguably vital. This paper aims to present a reliable, remote, Early Warning System (EWS) specifically designed for lava flood detection, along with its disaster communication system. The proposed system consists of two main subsystems: lava flood detection and disaster communication systems. It utilizes a modified automatic rain gauge; a novel configured vibration sensor; Fuzzy Tree Decision algorithm; ESP microcontrollers that support IoT, and disaster communication tools (WhatsApp, SMS, radio communication). According to the experiment results, the prototype of rainfall detection using the tipping bucket rain gauge sensor can measure heavy and moderate rainfall intensities with 81.5% accuracy. Meanwhile, the prototype of earthquake vibration detection using a geophone sensor can remove noise from car vibrations with a Kalman filter and measure vibrations in high and medium intensity with an accuracy of 89.5%. Measurements from sensors are sent to the webserver. The disaster mitigation team uses data from the webserver to evacuate residents using the disaster communication method. The proposed system was successfully implemented in Mount Merapi, Indonesia, coordinated with the local Disaster Deduction Risk (DDR) forum. Doi: 10.28991/esj-2021-SP1-011 Full Text: PDF

Abstract

The Menjer lake is the main source for Hydroelectric Power Plant of the PLTA Garung. Information about the water balance and the potential of existing water resources in the Menjer Catchment Area (DTA) is needed to obtain an efficient operating pattern, the sustainability of the Garung hydropower plant, and good management of the Menjer Lake. The purpose of this study was to estimate the inflow of three main rivers in the Menjer catchment area using HEC-HMS hydrological and water balance approach. Simulated results of the HEC-HMS model shows that the average of total the inflows of three main rivers to the Menjer lake in 2017, 2018 and 2019 during rainy season are 0.954 m3/s, 0.944 m3/s, and 1.017 m3/s, and during dry season are 0.820 m3/s, 0.783 m3/s, and 0.80 m3/s, respectively. While the prediction results of the discharge with the equation of the water balance shows that the average of total river inflows to the Menjer lake during rainy season is 2017 is 1.628 m3/s, in 2018 it is 1.579 m3/s, and in 2019 it is 3.296 m3/s and during dry season is 1.893 m3/s in 2017, 1.176 m3/s tahun 2018, and 1.893 m3/s in 2019. These results indicate that the results of discharge modeling with HEC-HMS are smaller than those predicted by the water balance equation. The study concluded that HEC-HMS could be used to predict daily inflows. However, further calibration and validation need to be carried out by recommending installing a river flow monitoring station at each river outlet.Keywords: water balance HEC-HMS, inflow prediction

Abstract

Progo River is one of the rivers that originated in Merapi Mountain. It is one of the active volcanoes, and if it erupted, so it resulted in an abundant material or sediment. The material from its eruption transported by water discharge will become a debris flow, that it gave damage and losses on infrastructure and inhabitants living around riparian areas. Based on the background, therefore, it is essential to do a research-related infrastructure and population in a riparian zone. The research objective is to study the accordance of the condition of the riparian zone of downstream Progo River based on the established rules. The method used was a field survey assissted by the application of Survey123 for ArcGIS. The data processing used ArcGIS software. The research result shows that some locations are not by the established rules on riparian areas. One of the most significant places having the highest settlement percentage included in riparian areas is Jatisarono Village Nanggulan Subdistrict, with the area of settlement of 0.1224 km square and 44.07% for the riparian zone with 50 m width and 0.1766 km square while 21.16% for the riparian zone with 100 m width. Jatisarono village also becomes the village with the highest approximate population number within the riparian zones with 135 people in the riparian zone with 50 m width and 195 people the riparian zone with 100 m width. From the field survey result, it finds that 13 rivers infrastructures along the downstream Progo River consisting of 10 bridges, two dams, and one groundsill (sample) are still in reasonable good condition.

Abstract

The alteration in land use causes the loss of infiltration areas replaced by rigid pavement yet demand for groundwater is increasing thus unbalance in hydrology cycle occurred and water became the problem for human as the problem for this country nowadays. One of the solutions to keep the storage of groundwater is to make the rain garden in the area near the run-off sources. Nonetheless studied about rain garden only focus on the effect of pollution in the river and study about the impact of reducing run-off debit and turbidity has not been explored yet. Three infiltration models that had been used for this research were infiltration model with soil-only, rain garden, and the rain garden with infiltration hole. The results presented by the study were compared to get the efficient value from each infiltration model in reducing debit and turbidity in the unsaturated and saturated soil. The result of this study showed that the rain garden model with infiltration hole performed better result with unit time reliability for 3 minutes and higher efficiency value of 54.17% on unsaturated soil and 53.81% on saturated soil. It can also reduce the suspension in the surface run-off until 0 mg/l.

Abstract

Aeration process is one of water treatment processes. The process consists of two physical phenomena, flow, and spreading of air bubble. This research has developed a finite element model for three-dimensional flow and spreading of air bubble. The flow equation employs Navier-Stokes equation. The spreading of air bubble is modeled as convection-diffusion equation. The Navier-Stokes and the spreading of air bubble equation are combined by Navier-Stokes equation with additional new term, which shows the accelerated flow caused by the air bubble moves. The Navier-Stokes equation was solved in four stages, i.e., Taylor Galerkin convection approximation, viscous prediction, pressure correction and velocity correction stages. Galerkin Standard method was used to solve the spreading of air bubble equation. Quadratic brick finite elements with 20 nodes were used on the geometry. To show performance model, comparison to the result of air bubble investigation was carried out. The numerical model that has been obtained is capable of simulating the phenomena of air bubble spreading and flow. The numerical stability analyses showed that the numerical scheme of convection and diffusion equation based on Galerkin is stable for Courant Number £ 0.01 and Peclet Number 125.

Abstract

DOI:10.17014/ijog.9.1.71-85Located in the ring of fire, Indonesia is widely covered by volcanic soil deposits in various hilly or mountainous areas, especially in Java Island. It is also being characterized as a tropical region, rainfall-induced slope failure in residual volcanic soil, and it is of practical significance to study its mechanism. This paper presents the study of the influence of rainfall and antecedent rainfall pattern on the stability of a residual slope in Yogyakarta. Two residual soil types, clayey sand, SC, and high plasticity clay, CH, were investigated in this study which is of different soil-water and hydraulic characteristics. The studied area was located in Kedungrong Village, Samigaluh, Kulonprogo. The rainfall record was obtained from the automatic rain gauge station in Kalibawang catchment area during November 2001. Two rainfall scenarios were modelled in the numerical analysis; those classified as the major rainfall that precipitates for thirty days (Condition 1) and the three influencing-rainfall (Conditions 2 to 4). Based on the simulation result from the major rainfall and the antecedent rainfall, the slope tended to fail when the precipitation went on continuously for three days with the so-called rolling rainfall pattern. The stability of the slope was dependent on the soil-water and hydraulic properties of the soil layer.
