Water Catchment

Increasing and developing infrastructure in urban areas has resulted in decreased water infiltration quality into the ground. The increasing of settlement needs and raising its price has resulted in many water catchment areas changing their function unconsciously in urban areas. This condition was ultimately triggering the loss of opportunities for rainwater to into the ground. At present, when the rainy season arrives, almost all major cities in Indonesia experience flooding. The torrential rains that lasted just 1 hour were enough to cause relatively high inundation, which varied from 30 cm to over 1m. This study aims to analyze the intensity of rainfall and its impact on the potential for flooding in urban areas and how to overcome it by utilizing rooter system technology. The results showed that the 4-way rooter system technology's influence was considerable in reducing the water level. An experimental area of 100 m2 treated with a rooter system of 16 pipes with a water level of 40 cm can infiltrate stagnant water into the soil within 120 minutes. Meanwhile, in the same area without rooter technology, it takes 400 minutes to absorb water into the soil until the stagnant water is completely gone. This proves that the rooter system technology plays a significant role in accelerating water absorption into the ground, reducing the risk of flooding.

Abstract An environmental problem that often occurs during the rainy season is standing rainwater. Therefore, some water catchment areas are needed to reduce standing water that will minimize environmental damage instead. In densely populated urban areas the available space for water infiltration is very limited. Using biopore infiltration holes’ technology which uses organic waste to increase the rate of water infiltration into the soil can be an alternative solution. This study aims to determine the effectiveness of biopore infiltration holes with organic waste treatment to increase the rate of infiltration of soil. The methodology used in this study is the Horton test, in which biopore infiltration holes are using PVC pipes with various diameter 3 in, 4 in, and 5 in. The measurement of the infiltration rate observed by decrease in water level every interval of 5 min, 10 min, 15 min, 20 min, 25 min, and 30 min continually. The results show that the effectiveness of biopore infiltration holes using PVC pipe with a diameter of 3 in, 4 in and 5 in are increasing 62.92%, 70.60%, and 54.11% respectively.

Abstrak. Kota Banda Aceh menjadi daya tarik bagi masyarakat sebagai sentral kegiatan pendidikan dan ekonomi, sehingga membawa pengaruh bertambahnya jumlah penduduk yang menyebabkan kebutuhan lahan semakin meningkat. Lahan yang sebelumnya berfungsi sebagai daerah resapan air tersebut mengalami konversi lahan yang menyebabkan berkurangnya daerah resapan air sehingga ketika terjadinya hujan dengan intensitas tinggi air hujan tidak secara maksimal terinfiltrasi ke dalam tanah dan terjadi penggenangan. Maka, diperlukan upaya untuk meresapkan air hujan yang efektif  ke dalam tanah dengan menggunakan lubang resapan biopori. Salah satu tempat yang ingin diketahui besarnya laju infiltrasi menggunakan lubang resapan biopori adalah di lima halaman rumah dengan luas bidang kedap yang berbeda. Penelitian ini bertujuan untuk mengetahui jumlah lubang biopori yang dibutuhkan di setiap rumah serta mengetahui jumlah volume air yang terinfiltrasi. Jumlah volume air yang terinfiltrasi pada rumah A yaitu 2,88 ml, pada rumah B yaitu 6,12 ml, pada rumah C yaitu 10,24 ml, pada rumah D yaitu 4,26 ml, pada rumah E yaitu 2,17 ml selama pengukuran. Jumlah ideal LRB yang dibutuhkan pada setiap halaman rumah A, B, C, D dan E berturut-turut adalah 82, 51, 27, 71, dan 230 lubang dengan intensitas hujan sebesar 6,62 cm/jam. Infiltration Rate of Absorption Holes Biopore Based on Type of Organic Material as Water and Soil Conservation Efforts Abstract.  Banda Aceh appeal to the public as the central economic and educational activities, this bringing the influence of growing population and increasing land needs. Increasing population it brings increased land requirements. Previous land serves as the water catchment area of land conversion experience leading to reduced water catchment areas. So, when it rains with high intensity of rain water, is not optimally infiltrated into the soil and flooding occurred. We need efforts are needed to effectively absorb rain water into the ground. One of the places to know the magnitude of infiltration using biopori absorption holes are in five broad areas of the home page with different impermeable. This study aims to determine the amount of absorption wells which are needed in every houses and to know the volume of water that infiltrated. The total volume of water that infiltrated the house of A is 2.88 ml, at the house of B is 6.12 ml, at the house of C is 10.24 ml, at the house of D is 4.26 ml, at the house of E is 2.17 ml for measurement. LRB ideal amount needed at every driveway A, B, C, D and E are respectively is 82, 51, 27, 71, 230 holes with rain intensity of 6.62 cm / hour.

The existence of a house on stilts when compared to residential houses of concrete can be said to be more environmentally friendly, especially in water catchment areas or marshy. However, the number of houses on stilts is decreasing. This is because the stigma of stilt houses which are generally made of wood is an average house for the lower classes, especially in urban areas. In addition to being more environmentally friendly, the stage house also has its own uniqueness, one of which is the shape and type of connections used to extend the dimensions of the wood material used. Therefore, to enrich the existing information, this study aims to identify the types of connections in the upper girder and stage bottom girders so that it is expected to help further research in the related field of research. This research uses descriptive qualitative method by using photo documentation and conducting interviews as supporting data. The results showed that there were several types of joints but generally used the connection of mortise and tenon, half lap, scarf joint, scarf joint with under-squinted ends and scarf joint with wedges which were aided by pegs, bolts and wood clamps.

Water Catchment

Continuous development causes changes in land use from open spaces as water catchment areas to become residential areas. The change in function of water catchment land causes rainwater that falls on the land not to enter the soil, but overflows on the surface of the soil. During the rainy season, most of the water will be discharged directly into the sea, otherwise it will cause puddles and flooding. Meanwhile, during the dry season, many groundwater sources experience drought. Naturally, groundwater shortages can be overcome if the management system is handled properly.The formulation of the problem in this study is how to apply infiltration wells to control rainwater puddles in residential areas.The working principle of an infiltration well is to distribute and collect rainwater into a hole or well, where the rainwater on the ground will then slowly seep into the ground. Below the ground, this seeping water will seep into the soil layer called the unsaturated layer, where this layer can still absorb water. Thus, the entry of rainwater into the ground will increase groundwater. The application of infiltration wells in residential areas requires calculation of the area covered by buildings and watertight. The number of infiltration well areas that need to be made is 4% of the watertight area.

The water catchment area also indirectly impacts on flood control for areas that are lower than it because rainwater does not fall to the lower areas but is absorbed as groundwater. Increased development of Padang City will be inversely proportional to the reduction in water catchment areas and become an area that is impermeable that makes rainwater stagnate on the surface and flood occurs. The development of remote sensing technology and geographic information systems has made it possible to study the spatial patterns of potential water catchment areas in a wide range, including mapping the potential of water catchment areas in Padang City. This study aims to analyze the condition of the availability of water catchment areas for controlling water management and flood disasters in Padang City based on data on spatial parameters such as rainfall data, slope, soil type maps, and land use obtained from Landsat 8 OLI imagery data. This study uses the scoring and overlay method with the Geographical Information System. The results show that the condition of the water catchment area in the western part of Padang City have been critical, reaching 18.29% of the total area of ​​Padang City, this is due to land use that has undergone a change of function. If the water infiltration condition worsens (critical), it gives more opportunities for flooding and inundation. Thus the areas with the potential for water absorption which are categorized as critical and very critical in the research location can be said to be areas that are potentially prone to flooding and inundation, because the ground surface is no longer able to absorb water. Monitoring the potential of water catchment areas is one form of flood mitigation efforts.

Human Wildlife Conflict

Abstract Coyotes are ubiquitous in habitats across North America, including in urban areas. Reviews of human–coyote encounters are limited in scope and analysis and predominantly document encounters that tend to be negative, such as human–wildlife conflict, rather than benign experiences. The objective of our study was to use citizen science reports of human–coyote interactions entered into iNaturalist to better understand the range of first person accounts of human–coyote encounters in Madison, WI. We report 398 citizen science accounts of human–coyote encounters in the Madison area between October 2015 and March 2018. Most human–coyote encounters occurred during coyote breeding season and half of all encounters occurred in moderate development land cover. Estimated level of coyote aggressiveness varied significantly, with 90% of citizen scientists scoring estimated coyote aggression as a 0 and 7% scoring estimated aggression as a 1 on a 0–5 scale (with 0 being calm and 5 being aggressive). Our best performing model explaining the estimated distance between the human observer and a coyote (our proxy for a human–coyote encounter) included the variables distance to nearest paved road, biological season of the year relative to coyote life history, and time of day/night. We demonstrate that human–coyote interactions are regularly more benign than negative, with almost all first-hand reported human–coyote encounters being benign. We encourage public outreach focusing on practices that can foster benign encounters when educating the public to facilitate human–coyote coexistence.
