    Get PDF
    Dynamic interactions of hydrological and geomorphological processes in the fluvial system result in accumulated deposit on the bed because the capacity to carry sediment has been exceeded. The bed load of the Aceh fluvial system is primarily generated by mechanical weathering resulting in boulders, pebbles, and sand, which roll or bounce along the river bed forming temporary deposits as bars on the insides of meander bends, as a result of a loss of transport energy in the system. This dynamic controls the style and range of deposits in the Aceh River. This study focuses on the spatial distribution of bed-load transport of the Aceh River. Understanding the spatial distribution of deposits facilitates the reconstruction of the changes in controlling factors during accumulation of deposits. One of the methods can be done by sieve analysis of sediment, where the method illuminates the distribution of sediment changes associated with channel morphology under different flow regimes. Hence, the purpose of this mini review is to investigate how the sediment along the river meander spatially dispersed. The results demonstrate that channel deposits in the Aceh River are formed from four different type of materials: pebble deposited along upstream left bank; sand located on the upstream, downstream, and along meander belts; and silt and clay located along the cut bank of meander bends. Because of different depositional pattern, the distribution of the sediment along the river can be used as a surrogate to identify bank stability, as well as to predict critical geometry for meander bend initiatio

    Progo fault is one of the active faults located in the south of Yogyakarta. Progo fault is suspected that located in Progo River estuary area, Banaran, DIY. However, studies are still needed to support the scientific basis of the position and the type of fault in Progo River estuary. Magnetic survey has been carried out in DIY Progo River estuary to determine the subsurface structure in the area. Data needed in the processing of magnetic data is a magnetic anomaly data obtained from the values of the total magnetic field strenghthas been corrected. In this study, magnetic data acquisition was carried out in 97 points by using a PPM (Proton Precession Magnetometer) geometrics 856X. Data Processing began with International Geomagnetic Reference Field (IGRF) correction and diurnal correction to get the total magnetic anomaly. The total magnetic anomaly contour created by using Surfer that has been used to process upward continuation and then made reduction to the poles. The result of research showed the total magnetic anomaly closure pair of positive and negative indicated a fault zone below the surface. Mag2D used to create 2D modelling to obtain the subsurface structure and susceptibility values. To reinforce the results of subsurface structure, 3- modelling has been created by used Mag3D. In 2D-modelling of subsurface structure is obtained in the form of fault zones in the west an the east of the River Progo. The interpretation is reinforced by the result of 3D-modelling in the area. There are tworeserve faults in Progo River estuary area, first in the west of the Progo River and second in east Progo River to a depth of 1000 meters

    Land suitability is one aspect that determines the success of vannamei shrimp cultivation in coastal pond areas. Cultivation of vannamei shrimp in ponds has a spatial component as well as differences in the biophysical and socio-economic characteristics of each location. Many ponds that are intensively managed have not taken advantage of the advantages of Geographical Information Systems (GIS) in selecting locations and managing vannamei shrimp culture, which is important to do to avoid business failure. This study used a survey method to collect data on water quality parameters (acidity / pH, temperature, salinity, dissolved oxygen / DO, nitrate, and phosphate). Analysis of land suitability for vannamei shrimp cultivation in ponds using the scoring method, each water quality parameter is weighted and a score is then divided into 4 land suitability classes, namely classes S1 (Very Suitable), S2 (Sufficiently Suitable), S3 (Conditional Appropriate), and N (Unsuitable). The results showed that the vannamei shrimp pond land suitability map produced a thematic map of the suitability of the vannamei shrimp pond land which had a total area of 13.65 ha of vannamei shrimp and had 4 levels of suitability, namely very suitable class (S1) with an area of 3.96 ha, a class that appropriate (S2) has an area of 7.8 ha, a moderately suitable class (S3) has an area of 0.85 ha, and an unsuitable class (N) has an area of 1.04 ha.Keywords: Litopenaeus vannamei; Water quality; Land Suitability; Geographical Information SystemsAbstrakKesesuaian lahan merupakan salah satu aspek yang menentukan keberhasilan kegiatan budidaya udang vannamei di wilayah tambak pesisir.

    This study aims to (1) identify the factors that influence the production of plant cane and ratoon cane, (2) determine the level of production efficiency of plant cane, ratoon cane, and poll, and (3) identify the factors that influence the inefficiency of plant cane and ratoon cane production. The data used was secondary data sourced from the production data for the 2017-2018 planting season with some inputs: land area, fertilizers, herbicides, labor, age of plants harvested and data of land types. From the analysis, it was revealed that (1) factors influencing the increase of plant cane production were land area, ZA fertilizer, harvest labor, and types of fields. Meanwhile, the influential factors impacting the increase of ratoon cane were land area, SP36 fertilizer, ametryn herbicide, harvest labor, type of fields, and HGU land type while estate labor, mechanization, and dummy varieties affect decreasing on it, (2) sugarcane farming was technically efficient (3) factors affecting the inefficiency for plant cane are formal education and rank levels of plant officer. However the coefficient of the formal education variable was negative  and the rank level coefficient was positive. A higher level of education will increase production, but a higher rank level of plant officer will decrease it. Improving education levels can be provided by giving mentoring or the provision of courses. In ratoon cane, there was no effect of technical inefficiency. So an increase in ratoon cane production can be done by increasing the use of production inputs
