Spatial Distribution of Traditional Market in Padang City Chairul Ichsan; ELVI ZURIYANI; Afrital Rezki
Geographica: Science and Education Journal Vol 1, No 2 (2020): June
Publisher : USN Kolaka

This study aims to spatial distribution of traditional markets in Padang City that which consist of: 1) Distribution spatial of traditional market, 2) Spatial patterns of tradional market, and 3) Range pattern of traditional market. Type of this research is descriptive research with spatial analysis technique. Population in this study are all traditional markets in the Padang City. Sample of this study was that all traditional markets in Padang were taken with a sampling technique. That is total sampling where the number of samples is equal to the population. The data analysis technique uses the analysis of the nearest neighbor index and buffer zone. The results of this study were found that: 1) Spatial Distribution of Traditional Markets in Padang City, there are 21 traditional markets spread across 9 Subdistricts: Koto Tangah District, Padang Utara District, Padang Barat District, Padang Timur District, Padang Selatan District, Lubuk Begalung District, Lubuk Kilangan Subdistrict, Kuranji Subdistrict, and Nanggalo Subdistrict, 2) The distribution pattern of traditional markets in Padang City is included in the pattern of uneven distribution (random), 3) Range pattern of traditional markets in Padang City with a radius of 5Km are more likely to focus in the city center or the western and northwestern parts of Padang City.

HYDROLOGICAL STUDY ON LIMESTONE MINE DRAINAGE SYSTEM IN PT. ADS - SOUTH SUMATERA Charly Bravo Wanggai; Ceni Febi Kurnia Sari

The groundwater availability in an area with mineral deposits is measured by the geological and geomorphological characteristics of the area. The hydrological study on limestone mining in PT. ADS, South Sumatera aimed to acquire data and information regarding rainfall characteristics, drainage basin and catchment area, infiltration value, and surface water flow pattern at the limestone mining site and nearby area; this is to formulate a basis of reference in creating drainage system. The study employed Extreme Value Gumbel formula to analyze the expected daily rainfall. A calculation on the rainfall return period relied on two factors, i.e., the planned mining duration and natural events, such as seasonal flood per two years. Moreover, Mononobe formula was used to calculate and convert the daily rainfall intensity in the form of hourly rate. The mine drainage system was regarded necessary in the site since the watery area is potential to hinder the production as well as to cause work accidents; on top of that, the terrain is dominated by relief of wavy hills with varying waves and slopes ranging from 10°-70°.

Indonesia is an agricultural country in the tropic area with a high potential of agricultural land. This condition is a good ecosystem for human, animal and plant life. With all those potentials, the population in Indonesia has reached more than 260 million people currently. Surely, such a large population brings logical consequences in which a large amount of land must be provided by the State to support the housing needs and to meet the food and clothing needs. As a matter of fact, the population of Indonesia continues to increase over the time. The increase in population in many areas has caused the conversion of agricultural land into residential land. Therefore, the agricultural land continues to have pressure constantly. The Population pressure to agricultural land is a comparison between the number of people and the minimum land area to be able to live properly. This study aims to analyse the variations of population pressure on agricultural land in each village in Mojolaban Sub-District. The research method used to analyse the population pressure was by utilizing the formula of Otto Sumarwoto I, where residents are considered to only live on cultivated agricultural land. The results showed that population pressure toward agricultural land in Mojolaban Sub District was high. There were 11 villages and 4 villages that were categorized as high and low population pressure on agricultural land respectively.

Based on the analysis result, the research sites are divided into three levels of mass movement vulnerability; low as much as 10,98, moderate as much as 84,41, and high as much as 4,61% out of the entire research areasMass movement occurs due to the natural process in the changes of surface structure, in which there is a disturbance of stability in the soil or rocks making up the slope. The disturbance is caused by some conditions such as a relatively steep slope, the condition of rock or soil making the slope, high rainfall intensity, uncontrolled human activity in exploiting the nature as well as the state of geological structures. The research site is located in three sub-districts in Bone Bolango District; Suwawa Timur, Suwawa Tengah, and Suwawa Selatan. These three sub-districts have a history of mass movement during the rainy season. The availability of up-to-date data is required to reduce the impact caused by the mass movement. This research aims to identify the areas prone to mass movement. One of the approaches applied to identify the areas prone to mass movement is Storie Index method by calculating the parameter, which is considered influencing the mass movement. Among others, the parameters are steepness of the slope, rainfall, type of soil, land usability, and lineament density as the parameter of geological structures.

Publisher : USN Kolaka

The coastal region is one of the areas directly affected by climate change. Coastal communities are the ones with the highest level of vulnerability to the effects of climate change. Kaliwlingi Village is one of the coastal areas in Brebes Regency which is vulnerable to tidal flood disasters. This study aims to determine the impact of tidal floods in Kaliwlingi Village, Brebes Regency and determine the community's approach to tidal floods. This research uses a qualitative method with a descriptive narrative approach. In this case study the data analysis was obtained from Miles and Huberman's analysis in terms of data reduction, data presentation and conclusion drawing. Based on the results of the study note that tidal floods affect various aspects of life such as physical aspects, economic aspects and environmental aspects. Most people adapt to tidal flooding by raising their houses, making embankments and roadside and planting mangroves.

For the population of Playen District, Gunungkidul Regency, karst springs serve as the primary water sources because surface rivers are rare in karst areas and, if present, the quality of their water is reportedly less than that of the springs. In the spring water utilization, local wisdom is incorporated into the management and has so far contributed to sustainability. Since only a few studies have examined local wisdom and its correlation with changes in spring management pattern, this research initiates the provision and dissemination of information on karst spring management that is applicable elsewhere. It was designed to scrutinize the local wisdom and regulatory measures implemented at many springs in Playen District. Detailed data were obtained by in-depth interviews with four key informants responsible for managing springs block 1 (Gedad, Grunggung, and Karangkulon Springs), 2 (Banyusoco and Sungai Oyo), 3 (Dung Poh, Nganding, Umbul, and Jambe), and 4 (Ngrunggo and Ngrasih). Through qualitative descriptive analysis, the research found that the laying of offerings at springs in blocks 1 and 2 during traditional celebratory ceremonies had been abandoned, but cleaning activities at and around these springs as part of the local wisdom sustained. In the context of utilization, the spring management had changed from direct manual withdrawal to indirect systematized one that used pipes with gravitational water flow system (block 1) to distribute spring water to villagers’ houses (block 2). On the contrary, local wisdom like offerings and cleaning activities at and around the springs in blocks 3 and 4 was preserved. Their management had changed from manual extraction to gas-fueled water pumping systems, which were later replaced with electricity-powered pumps (block 3), and to indirect withdrawal through pipelines with pump-generated flows (block 4). To manage the springs in all blocks and their sustainable utilization, the people of the district still adopt local wisdom. Besides, they no longer collected water directly at springs but have switched to water distribution technology like pumps and pipelines instead.
