Abstract

The western waters of Sumatera are one of the waters that have the potential of coastal and ocean resources. Oceanographic factors that can be related to high productivity in waters are SST (Sea Surface Temperature) and the distribution of chlorophyll concentration. Sibolga waters are geographically quite strategic, because they are located in the Indian Ocean, most of the catch is landed at the Sibolga Nusantara Fisheries Port. This Study aims to understand the trend of fluctuations in fish catches in the The Waters of Western Sumatera, to examine the effect of chlorophyll on fish catches in the waters of West Sumatera. Sea surface temperature and monthly chlorophyll-a concentrations were obtained from the result of the Aqua Modis months in 2021. Monthly data and data on fishing results were obtained from the Sibolga Nusantara Fisheries Port. The composition of catches in the western waters of Sumatera which landed at PPN Sibolga in 2021there three dominant fish species, namely Cakalang (Katsuwonis Pelamis) 11.655.768 Kg, Layang (Decapterus Sp) 4.589.147 (19,95%), Tembang (Sardinella sp) 2.421.523 (10,53%), the variation of fish catch per unit (CPUE) ;anded at PPN 2021. The Highest occurred in may at 3.809 kg/trip and the lowest occurred in November 1.521,58 kg/trip and the average monthly CPUE in 2021 was 5.105,88kg/trip. Monthly variations of sea surface temperature and chlorophyll-a in the waters of for 12 months (2021) the lowest temperature occurred in August, namely 26,88 0C while the highest temperature in February was 30,92 0C, the highest consentration was in May of 1,56 mg/m3 while the lowest occurred in March at 0,15 mg/m3.

Abstract

Land use is the physical form of the earth's surface that is influenced by human activities. The increase in population results in changes in land use for settlements that tend to increase and are not controlled, so it is necessary to monitor the rate of these changes so that the balance of life and the environment can be maintained and in accordance with what has been regulated by the government in the regional spatial plan (RTRW). This study aims to identify changes in settlement area from 2010-2020 in Solok City and assess the suitability of land use for settlements with residential spatial patterns (RTRW) in 2012-2031 Solok City. This study uses remote sensing data in the form of spot images. The steps taken by the image interpretation approach with manual digitization methods and arcgis applications, accuracy sampling is done by random sampling with the confusion matrix accuracy test technique carried out to answer the goal. The results of the study found that the image accuracy was 91.66%. Then, the condition of settlements in Solok City continues to increase in area every year in the 2010-2020 period with a total of 353.8 Ha, where the largest area of ​​settlement changes is in Lubuk Sikarah District. In this study, it can be stated that the area of ​​settlement in 2020 is 306.50 Ha which is not in accordance with the area contained in the spatial pattern (RTRW) of Solok City

Abstract

The geographical conditions of an area influence accessibility problems. The difficult geographical conditions caused travel time to the location of the obstetric emergency center to be very long. One of the causes of the high maternal mortality rate in Eastern Indonesia is the long time to travel to Basic Emergency Obstetrics Cares. This study aims to model the travel time to the PONED-Pelayanan Obstetri Neonatal Emergensi Dasar (Basic Emergency Obstetric and Neonatal Care-BEmONC) in a mountain region. The difficulties in access to obstetric care could cause maternal mortality in mountain regions. This study was done on the island of Adonara in the Flores Timur district. Adonara Island has a high maternal mortality rate. Modeling accessibility used a raster-based model to model travel time. The data used Landsat 8 imagery, Digital Elevation Model (DEM), and road network data to obtain a land cover layer. The Saga GIS travel time calculation tool is used to calculate the accumulated cost of travel time. The cost is based on the speed of travel through each land cover pixel to the location of the Puskesmas Waiwerang (PONED 1) and Puskesmas Waiwadan (PONED 2). The results of the travel time modeling show that people living in five sub-districts reach the two PONED locations in ≥ 1 hour. The longest time for people to travel to PONED is ≥ 6 hours from Ile Boleng sub-district because there is a mountain in the Ile Boleng sub-district. The scenario of adding one PONED shows that only people living in two sub-districts reach the PONED ≥ 1 hour. This spatial modeling of travel time to the location of the PONED (emergency obstetric care) can be used by local governments in eastern Indonesia to improve access to the location of basic obstetric emergency health centers in mountain areas.

Abstract

The life of maritime flora and wildlife are substantially impacted by oil's effects, and this has an immediate impact on livelihoods. The impact disrupts the lives of contaminated coastal communities. Because of the potential losses caused by oil pollution, the government enacts policies governing environmental conditions in order to maintain or improve the quality of the polluted sea. The purpose of this study was to calculate the acoustic backscattering value of oil using a single beam echosounder and compare the measurement results from a single beam echosounder with the results of gravimetric analysis. The data acquisition was carried out in March 2021 at the Marine Acoustic Laboratory, Department of Marine Science and Technology, Faculty of Fisheries and Marine Sciences, IPB University, using the SIMRAD EK-15 frequency of 200 kHz and oil used as a source of pollution, namely the dexlite type (density of 880 kg/m3). The results showed that the value of Surface Backscattering Strength (SS) decreased when contaminated with oil, namely -63.76 dB and -65.90 dB, but when oil was added back, the SS value increased to -50.81 dB. The relationship between oil concentration and surface backscattering strength shows a negative correlation between the variables, and the level of the relationship between variables is 0.85.

Abstract

Coastal areas are characterized by complex dynamics between freshwater entering through the estuary from land and seawater from open water. This study aims to calculate the salinity anomaly found on the sandy coast of Mayang, estimate the number of fractions and the volume of mass transport of fresh water entering the waters through the river flow and measure the total dissolved solids (TDS) in the west season. Water mass characteristics data collection using Water Checker. The determination of 17 data collection stations is assumed to be representative in representing the overall condition of the research location. The results of the anomaly salinity calculation show the low anomalous salinity values that are distributed horizontally on the coast. The distribution of salinity as anomaly values transversely on lines 1 to 4 ranges from -1 to -15. Freshwater fraction is concentrated as far as 1.16 km from the coast of Pasir Mayang with concentration values ranging from 0.44% to 0.13%. The mass transport of fresh water in the Pasir Mayang coastal waters is 1,130 m3s -1. The value of the transport volume of fresh water depends on rainfall and the flow of fresh water through rivers and then into sea waters. The total dissolved solids at the study site at each station ranged from 7.88 ppm to 17.8 ppm.

Abstract

Land-use change is the main cause of high runoff compared to other factors. The type of land use also plays a role in determining the amount of runoff that occurs. The Upstream Ciliwung watershed is blamed as the main causes of the flood disaster in Jakarta, the capital city. The land use in the upper stream has changed and causes increasing of run off to be higher than the capacity of river to drain it. This study aims to explore the land use changes of the Upstream Ciliwung Watershed from 1996 to 2016 and their consequences on the stream run off. Furthermore, the study also recommends the efforts needed to reduce river water discharge. The land use changes are identified by using spatial analysis method. The calculation of run off uses the rational method. Average rainfall data for every ten years is calculated by use of Gumbell distribution formula. The study shows that in the period 1996 – 2016, there was a change in land use in the upstream Ciliwung watershed. The area that continues to decline includes primary forest, open land, paddy fields, shrubs, and mixed gardens, all of which are categorized as undeveloped areas. The runoff discharge from 1996 – 2016 has increased from 278.77 to 465.57 mm/second that indicate runoff discharge is already in the Standby I position. Efforts that need to be made to reduce runoff water flow in the Ciliwung watershed are: 1) consistently develop and control land use change in the area based on the Jabodetabekpunjur Spatial Planning 2) consistently apply the building coverage ratio (BCR) regulation; 3) construct engineering and technology approach such as build infiltration wells in settlement, 4) forest rehabilitation and 5) conducting law enforcement.

Abstract

Majalaya District is one of the areas close to the Upper Citarum River. Agricultural land in some areas in the district is converted for industrial development. This causes a decrease in the quantity and quality of agricultural land. The existence of land conversion can affect morphological changes. The study aims to determine the pattern of land use changes and determine the morphology of regional development in 2014 and 2021 in Majalaya District, Bandung Regency. The spatial analysis method is done by on-screen digitization, descriptive analysis and figure ground analysis. The results of this study are the pattern of land use changes using figure ground method and descriptive analysis of the morphology in Majalaya District between 2014 and 2021. Based on the results of figure ground analysis calculation on the solid classification of industrial class in 2014 it was 182,310 Ha (25%), while in 2021 it was 258,905 Ha (27.19%). Morphological analysis of the district is based on the pattern of building plots, road network patterns and building systems from 2014 to 2021. The analysis results show the district morphology of octopus/star shaped cities and unpatterned cities. This form is influenced by the development of industrial buildings in Majalaya District which causes the morphology of the area also to change.

Abstract

The Batang Singkut River section is a tributary of the Batang Asai River which passes through Pelawan District and Singkut District. This research was carried out by calculating the design flood discharge and modeling the water level using HEC-RAS. The starting point of the research is on the bridge around the Jambi University campus in Sarolangun Regency with the length of the river under review being 300 meters. The discharge data used is the maximum daily discharge for 10 years from 2011 to 2020. The method used to calculate the design flood discharge is the method of frequency analysis and distribution testing using the chi-square method. The analysis was carried out to find the design flood discharge frequency using the Pearson III log distribution type for return periods of 2 and 5 years. The calculated discharge is entered into the HEC-RAS to model the water level. The modeling results showthat at a 2-year return period for cross sections STA 0+00, STA 1+00, STA 1+50, STA 2+00, STA 2+50, and STA 3+00 are able to accommodate water with a discharge of 83.5026 m3/s, but for the STA 0+50 cross section it is unable to accommodate the amount of discharge generated. Whereas for the return period of 5 years the cross section of STA 0+00 to STA 2+50 is unable to accommodate water with a discharge of 118.4132 m3/s, while for STA 3+00 the cross section can hold water.
