Abstract. Population growth in Padang City in 2007-2017 has increased from 838,190 people to 927,168 people (BPS Kota Padang, 2018). With this increase, the need for land / shelter and water needs is also increasing. This has resulted in high development, both in the city center and in the eastern suburbs. In addition, there is also a change in land use functions from forest areas, agricultural land, water catchment areas and cultural heritage lands to residential areas dominated by houses and concrete roads covering the ground. So that the reduced protected areas that function as water catchment areas and sources of clean water. Then with the rainfall in Padang City which is quite high, namely 4,661 mm³ / year, it causes puddles of water every time it rains. Therefore, it is necessary to plan the placement of infiltration wells around the Batang Kuranji watershed based on the value of infiltration rate, water physical quality, and soil texture.The research was conducted at 29 points that spread throughout the Batang Kuranji watershed. The data obtained are primary data, namely data on the physical quality of water (pH, redox potential, conductivity, TDS, salinity, resistivity, DO) and coordinate data.Based on the infiltration data, the average value of infiltration is 0.045710 cm / minute which is included in zone VI / E which is classified as low (<0.1 cm / minute). After conducting research with statistical analysis, physical water quality, rock lithology conditions, ground water level, and land use in the Batang Kuranji watershed, the placement of infiltration wells spread across almost all parts of the Batang Kuranji watershed which is a residential area, public service facilities. , industrial areas and fields. The number of infiltration wells to be placed is 9 points.Keywords: Infiltration Well, Infiltration Rate, Physical Quality of Water, Lithology of Rocks, Land Use.

Abstract

Masalah dalam penelitian ini adalah rendahnya teknik reservice atlet Sepaktakraw LTC Kecamatan Matur. Tujuan penelitian ini untuk mengetahui pengaruh latihan individu dan berpasangan terhadap kemampuan reservice atlet Sepaktakra LTC Kecamatan Matur. Jenis penelitian ini adalah eksperimen semu. Populasi dalam penelitian ini adalah semua atlet sepaktakraw LTC Kecamatan Matur. Jumlah sampel adalah 8 orang atlet. Instrument penelitian ini dengan mengukur kemampuan reservice. Teknik analisis data menggunakan analisis uji t. Latihan sepaksila individu dapat meningkatkan kemampuan reservice atlet Klub Sepaktakraw LTC Kecamatan Matur, hal ini dibuktikan dengan thitung = 4,70 >ttabel = 2,35 2) Latihan sepaksila berpasangan dapat meningkatkan kemampuan reservice atlet Klub Sepaktakraw LTC Kecamatan Matur, hal ini dibuktikan dengan thitung 3,00>ttabel = 2,35, 3) Tidak terdapat perbedaan pengaruh latihan sepaksila individu dengan latihan sepaksila berpasangan terhadap kemampuan reservice atlet Klub Sepaktakraw LTC Kecamatan Matur, ini dibuktikan yaitu; thitung = 0,31<ttabel = 2,35, hipotesis ditolak

Abstract

Mathematical reasoning ability is one of the abilities that must be possessed by every student in mathematics learning. But in reality the mathe|matical reasoning abi|lity of class VIII stu|dents of SMPN 8 Padang is n|ot op|timal. One of the factors that causes it to occur is learning that has not been fully able to facilitate students to develop mathematical reasoning abilities properly. Efforts can be made to improve students mathematical reasoning ability, one of which is to implement discovery learning models. T|he pur|pose of t|his stu|dy wa|s to deter|mine the differenses in mathe|matical reasoning abil|ities of stu|dents who use discovery lear|ning wit|h mat|hematical reasoning abilit|ies that use conventional lear|ning in the class VIII of SMPN 8 Padang. This type of research is a quasi-experimental research design with Static Group Design. The population in this study was class VIII SMPN 8 Padang with samples class VIII.E and VIII.F. The research instrument used was a tes of mathematical reasoning ability in the form of esaay quastion. Based on the analysis of the date from the final tes results obtained that at a significant level og 0,005 by performing the t-test obtained P-value = 0,048 because the P-v|alue < α th|en H0 is re|jected. This shows that students mathematical reasoning abilities with convensional learning in class VIII of SMPN 8 Padang. In this case, it can be concluded that the discovery learning model influences students mathematical reasoning abilities. Keywords – Discovery Learning Model, Mathematics Learning, The Ability of Mathematical Reasoning
