Abstract

Recently, agricultural production in the Sampean Baru Irrigation area has not shown optimal cropping production. The average percentage of planted areas in the first (November-February),second (March-June), and third (July-October) planting seasons for the upstream area was 93.67%; 98.02%, and 76.76%, and for the downstream area was 83.54%; 80.81%; and 89.36%. This research aims to optimize the water distribution system based on the calculation of water requirements for plants and the availability of channels to obtain the maximum planting area and amount of agricultural production. This optimization method uses a Dynamic Program with three scenarios. This calculation is based on effective rainfall, crop water requirements, and water discharge availability. Percentage of planted area obtained from the calculation in the dry year for the first, second, and third planting seasons respectively were 100%, 100%, and 90.36%. Based on the existing condition, potential profit obtained for a year is Rp. 170.08 billion. After optimization using Dynamic Program, potential profit in the dry year, normal year, and wet year are IDR 213.52 billion, IDR 215.92 billion, and IDR 228.50 billion, respectively.

Abstract

Flood disasters frequently occurred in Jember Regency, East Java. It is usually caused by the overflow of the Tanggul River in the rainy season, especially in the downstream area. Flood control could be done by building dams, embankments, shortcuts, and other technical flood protections. Meanwhile, mitigation efforts such as developing thematic maps of flood inundation need to be done to minimize losses caused by the flood. This study aims to design a flood mitigation strategy technically. The flood control structure was proposed by designing a shortcut in Kali Tanggul. Its performance was analyzed to reduce flood inundation in the Tanggul watershed. The flood inundation modeling was carried out using spatial analysis using ArcGIS 10.1 and hydraulic analysis using HECRAS 5.0.3. Flood inundation results were compared with the Tanggul watershed flood map developed by UPT PUSDA Lumajang. Based on modeling results, flood control using shortcuts is considered an effective strategy for flood mitigation. It was indicated by the reduction of flood inundation distributions, flood inundation height, and flood-affected areas. The results show that the flood height decrease 0.47 up to 0.56 m

Abstract

Tsunami risk level mapping was carried out in Ambulu Sub-District, Jember Regency, to determine the tsunami risk level in the area. Tsunami risk mapping was carried out by including several components such as vulnerability, which consists of several assessment aspects by the Chief of the National Disaster Management Agency Regulation of the Year 2012, and capacity, which is weighted according to the Chief of the National Disaster Management Agency Regulation of the Year 2012. The hazard component was generated from the bathtub method. The tsunami risk level was obtained after overlaying using a GIS application (Geographic Information System). A very high level of risk is found to apply for Sumberejo Village, with an area of 286 Ha, and Sabrang Village, with an area of 288 Ha. Villages at very high risk are directly adjacent to the coast and have high vulnerability and low disaster management capacity. The other villages, such as Karanganyar Village, Ambulu Village, Tegalsari Village, Andongsari Village, and Pontang Village, do not have a very high tsunami risk because they are far from the coastline and have low vulnerability and high disaster response capacity.

Abstract

The tsunami of June 3, 1994, which originated from a shift in the Indo-Australia plate, resulted in hundreds of casualties and material damage on the south coast of Jember. This study aims to understand the tidal impact of a tsunami in terms of arrival time and wave height. Several simulations of the interaction of tidal waves with tsunami waves were carried out through numerical modeling using Delft3D with modified wave characteristics from the Banyuwangi tsunami on June 3, 1994, as well as using bathymetry data from BATNAS and BIG tide data. The results of the analysis show that tidal waves can be a factor affecting the height of the tsunami waves. The increase in the amplitude of the tsunami waves was considered very local from the three observation points. This is shown at the observation locations of Puger Beach and Watu Ulo Beach, where the maximum wave amplitude occurs when the tsunami occurs independently of 7.102 m and 5.56 m, while at the Tanjung Pelindu observation location, the highest amplitude occurs when the tsunami meets the tides during low tide phase, which is 3.68 m. This research is expected to provide a basic understanding of the dynamic impact of the tidal wave when a tsunami occurs.

Abstract

The difference in rainfall intensity affects the hydrological cycle as a process that greatly determines the amount of water discharge. Thus, in water resources management, it is important to determine the distribution pattern of rainfall and discharge. By studying the characteristics of rainfall distribution patterns and water discharge, the potential of water resources can be illustrated well. This study uses the Exploratory Spatial Data Analysis method to examine spatial variability of rainfall intensity and water discharge in Bondowoso Regency. Rainfall and discharge data are collected from 35 rain stations and 227 weirs in 2008 until 2018. This study produces monthly average rainfall distribution values between 190 mm / month with monthly average discharge between 7300lt/sec/month. Meanwhile, the obtained average annual rainfall distribution values are between 2300 mm/year with annual average discharge values between 105000 lt/sec/month. The spatial distribution map using IDW method produces information on the potential of water resources as follow: the higher the height of a place, the higher the average monthly rainfall, while the lower the height of a place, the higher the average monthly discharge. As for the obtained correlation value between rainfall and discharge is R² = 0.665.

Abstract

Drought disasters that occur in the Sampean watershed from time to time have increased, both the intensity of events and the area affected by drought. The general objective of this research is to develop an assessment method for the impact of climate chan ge on vulnerability to drought disasters based on atmospheric circulation data. The specific objectives of this study are to model rainfall predictions based on atmospheric circulation data, predict rainfall in various climate change scenarios (Intergovernm ental Panel on Climate Change, IPCC – AR5), and assess vulnerability to drought disasters using a meteorological approach. The Standardized Precipitation Index (SPI) is one way to analyze the drought index in an area which was developed previous researcher. The Standardized Precipitation Index (SPI) is designed to quantitatively determine the rainfall deficit with various time scales. The advantage of the Standardized Precipitation Index (SPI) is that it is enough to use monthly rainfall data to compare drou ght levels between regions even with different climate types. To facilitate the presentation of the data base on the identification of d rought susceptibility, we need a system that can assist in building, storing, managing and displaying geographically ref erenced information in the form of spatial mapping. This research facilitates monitoring of the area of drought-prone areas, predicts drought levels, prevents future drought disasters, and prepares plans for rebuilding drought-prone areas in the Sampean watershed.

Abstract

Currently, water demand is increasing, both domestic, industrial and agricultural water needs. However, the increase in water demand is not due to an increase in the water availability due to changes in land use and other factors that pose a threat to increased exploitation of water resources. So it is necessary to analyze and evaluate the water needs to anticipate the impact of drought in the Asem-Tekung-Jatirowo sub watersheds. The calculation of water supply and water demand can be carried out using the water balance method, assisted by the WEAP (Evaporation and Water Planning) program, through data integration of streamflow analysis and water user in the river reach. The results showed that the sub-watershed area showed a deficit of water in 2013, with the Jatiroto region having the highest air deficit of 1.58 million m3 or 44.2%. Based on this analysis, urgently needed a recommendation of drought anticipation strategies these are planting patterns to adjust condition of water supply, storage of water reserves, conservation of critical land, and repair of channels that are at risk of water seepage.

Abstract

Kabupaten Pati, Provinsi Jawa Tengah merupakan daerah yang sering mengalami banjir diantaranya  banjir rob dan banjir bandang pada musim penghujan. Balai Besar Wilayah Sungai Pemali-Juana telah merencanakan pembangunan bendung karet yang telah dibangun pada tahun 2022 -2024 untuk mengatasi permasalahan tersebut. Bendung Karet ini diharapkan mampu menjadi solusi pengendalian banjir maupun sebagai sistem penyimpanan air pada saat musim kemarau. Penelitian ini bertujuan untuk memodelkan karakteristik hidrolik aliran di Bendung Karet Juwana pada kondisi banjir berbagai kala ulang (10, 20, 25, 50, dan 100 tahun). Pemodelan karakteristik hidrolik aliran menggunakan bantuan perangkat lunak HEC-RAS 5.0.3. Hasil pemodelan menunjukkan bahwa pada kondisi bendung karet mengembang maksimal terjadi aliran balik (backwater) sepanjang 2,26 km ke arah hulu bendung. Ketinggian muka air di atas bendung karet sebesar 1,0 meter dengan kecepatan aliran di hulu dan hilir ambang bendung masing-masing sebesar 0,40 m/dt dan 0,66 m/dt. Pengendalian tinggi muka banjir terhadap overtopping dapat optimal jika pada saat ketinggian muka air 0,60 meter diatas mercu. Secara hidraulik, hasil simulasi menunjukkan kecepatan pengempisan 0,2 meter/menit dapat mengontrol terjadinya overtopping secara optimal.
