Abstract

Salah satu cara pengolahan air yang sederhana dan ramah lingkungan adalah melalui proses penyaringan dengan instalasi penyaringan air sederhana (IPAS) menggunakan bahan alam. Bahan alam yang dapat digunakan sebagai filter dalam instalasi penjernihan air sederhana adalah pasir silika dan lempung alam yang diaktivasi. Pengambilan sampel sungai akan dilakukan di DAS (Daerah Aliran Sungai) Kahayan Kalimantan Tengah. Sampling air akan dilakukan pada saat musim kemarau sehingga tidak ada pengaruh pengenceran. Filter pasir silika dan kerikil diperoleh dari toko penjual ikan hias yaitu pasir ukuran halus dan kasar. Filter lempung mangan dapat dibuat dengan menggunakan lempung alam yang perlakukan dengan MnCl2 dan KMnO4. Hasil pengujian menunjukkan filter lempung mangan dan arang aktif mampu menyaring zat-zat berbahaya yang terlarut dalam air, menghilangkan bau dan menjernihkan air sungai kahayan yang keruh. Air sungai kahayan yang sebelum dilakukan penjernihan memiliki nilai pH 5,5, kandungan Fe 2,16 mg/L, total padatan tersuspensi (TSS) 258 mg/L, total padatan terlarut 30 mg/L, kekeruhan 140 NTU dan sangat bau. Setelah dilakukan penjernihan dengan instalasi penjernihan air, penjernihan memiliki nilai pH 6,5, kandungan Fe 0,7 mg/L, total padatan tersuspensi (TSS) 134 mg/L, total padatan terlarut 32 mg/L, kekeruhan 35,3 NTU dan tidak berbau. Hasil penjernihan air ini cukup layak digunanakan sebagai air bersih karena nilai pH, kandungan Fe, TDS, TSS, kekeruhan dan bau sesuai dengan syarat air bersih menurut Permenkes RI No: 416/MENKES/PER/IX/1990.

Abstract

This research is motivated by the statement that based on observation and interview which suspected that there was a problem with student interest in the subject of finishing of building in class Stone and Concrete Construction Techniques, thus adversely affects the learning outcomes of students with an average grade achieved only 55 whereas for minimum completeness criteria set is 70. The low student interest allegedly affected by many factors, some of which the subject matter is deemed less important and less useful and elusive, the attitude and the way teachers teach less gimmicky, less conducive environment or often noisy. This study aimed to determine whether there is a relationship between interest in learning with student learning outcomes in the subject matter of finishing the buildings in class XI Engineering Construction Stone and Concrete SMK 1 Palangka Raya. This study uses a quantitative approach to the type of research method of correlation which is a statistical analysis looking for a relationship variables X (interest in learning) and Y (learning outcomes). The sample in this study used a sample of saturated or all members of a population of 26 students. Data collection instruments interest using a questionnaire which refers to the Likert scale and the data collection instruments of learning outcomes using test questions. After the instruments tested and found suitable for use in collecting the data, then the data that has been collected is tested to meet the requirements analysis. Once the data is deemed eligible, the data variables X and Y are analyzed using statistical analysis Pearson Product Moment correlation. The results of the data analysis and the findings showed that students' interest in class XI Stone and Concrete Construction Technique in good condition, it is the most prominent because it is influenced by media using projector. Increased student interest also followed by the high student learning outcomes in building finishing materials, proved more students scored above the minimum completeness criteria. The results of data analysis using Pearson Product Moment correlation also showed a correlation or a positive and significant relationship between interest in learning with learning outcomes, with a correlation coefficient (rxy) of 0.482 and a correlation coefficient in the table (rtable) is equal to 0.404. Because rxy(0,482) > rtable (0,404), H0 is rejected and Ha accepted(Ha: r#0).
