Abstract

The Alabio polder irrigation which area of 6000 ha is situated at the Negara river basin in Kalimantan Selatan province, consist of agricultural land which major part is approximately used for paddy-fields (60%), swamp zone (30%), and other (10%). During rainy season are usually flooded, which water level of 0,50 – 1,50 m above the ground surface. The flooding is due to the slight slope of the Alabio, Panggang, and Negara river. During field investigatiton period from Desember 1989 to Pebruary 1990, inflow discharge measured in the Tabukan intake was 14,9 – 17,1 m3/det, which water elevation was 2,62 – 2,74 m MSL, in Mahar intake was 0,52 – 2,67 m3/det, which water elevation was 2,94 – 3,25 m MSL. The outflow discharge measured in the Kalumpang drainage main canal was 1,68 – 17,1 m3/det, and in the Luang drainage canal was 13,62 – 16,92 m3/det. The Alabio Polder outside slope was 0,00011 – 0,00025, the inside slope was 0,00002 – 0,00010. The difference of water level elevations for the various discharge in the Alabio canals network is due back water in the downstream Polder area. Sedimentation was accour in the intake and drainage canals. The chemical analyze show that surface water meet to the standard for irrigation. The hydrologycal optimation and water balance study should be necessary.

Abstract

Pelaksanaan pembelajaran Fisika terkadang tidak menggunakan pendekatan yang menarik, sehingga siswa merasa bosan, kurang kreatif dalam berpikir dan sulit untuk mengembangkan ide atau gagasan yang dimiliki. Oleh karena itu, sangat dibutuhkan suatu pendekatan yang dapat menciptakan peluang siswa untuk mengkonstruksi dan menumbuhkembangkan pengetahuannya, salah satunya adalah dengan menerapkan pendekatan SETS. Penelitian ini bertujuan untuk menganalisis pengaruh pendekatan Science, Environment, Technology, Society (SETS) terhadap hasil belajar siswa pada Materi Tekanan Hidrostatis di kelas XI SMA Negeri I Unggul Darul Imarah. Penelitian ini menggunakan metode Quasi Eksperimen dengan desain Nonequivalent Pretest Posttest Control Group Design. Data hasil tes dianalisis dengan menggunakan rumus uji Wilcoxon Sign Rank Test. Hasil penelitian dari Wilcoxon Sign Rank Test menunjukan bahwa Zhitung > Ztabel  yaitu -0,07 > 434 untuk taraf signifikan 95% dan ɑ = 0,05. Sehingga Ha diterima, dapat dilihat adanya peningkatan empat dari enam indikator pada kelas eksperimen dibandingkan dengan kelas kontrol. Hasil analisa tersebut menunjukkan bahwa pendekatan Science, Environment, Technology, and Society (SETS) berpengaruh terhadap hasil belajar siswa pada Materi tekanan Hidrostatis.

Abstract

Learning about laboratory equipment is often done. However, at the end of the learning that is often carried out tests is knowledge. While the skills possessed by students are rarely carried out tests, even though skills are part of the competencies that must be achieved. This can be caused by the unavailability of test kits that can be used to measure skills. Therefore in this study researchers conducted research on the development of physics student skills tests using basic physics measuring instruments in the Fkip Unsyiah Physics Education laboratory. This study aims to obtain a skill test device using a valid basic physics measurement tool for physics education study program students. The products produced are in the form of assessment instruments in the form of rubrics on a scale of 1-3. This study uses the development model Rowntree which consists of three stages, namely: 1) Planning; 2) Development; and 3) Evaluation. The results showed that the instrument validation obtained a percentage of 80% with a very feasible category. While the results of the average percentage of practical performance using calipers is 90.3%, micrometer 92.1%, voltmeter 81.5%, and ampermeter 81.6%. That is, the average percentage of student performance is categorized as very feasible.
