Abstract

Chemical laboratory liquid waste Environmental Pollution Control Techniques Cilacap State Polytechnic is liquid waste originating from practical or research activities of lecturers / students. Most of the waste contains organic and inorganic substances that are harmful to the environment. In the initial analysis the results of the wastewater content were in the form of lead less than 0.251 mg / L, Hardness 213.33 mg / L, TDS 4690 ppm, and pH 1.6. One parameter that needs to be addressed is TDS because dissolved solids can affect the O2 levels contained in the waters. In this research, a prototype of a waste processing tool was used to process the waste. In this research the method used is the process of coagulation, electrocoagulation and sedimentation in batch with a variation of residence time which affects the product. In addition, the filtration and adsorption process uses a continuous system, so that overall the tool uses a semi-batch system. In this study the chemicals used for processing were CaCO3 and citric acid. Then the adsorbent used is zeolite and activated charcoal as absorbent of dissolved solids. This waste treatment tool is considered quite effective in reducing TDS with a final result of 2950 ppm.

Abstract

Tujuan penelitian ini untuk mengetahui pengaruh strategi formasi regu tembak dalam pembelajaran mendramatisasikan teks drama. Metode yang digunakan dalam eksperimen semu. Sampel penelitian berjumlah 60 orang siswa dengan rincian 30 siswa kelas XI. TAV 2 sebagai kelas eksperimen dan 30 siswa kelas TAV 1 sebagai kelas kontrol. Teknik pengumpulan data menggunakan teknik tes, sedangkan teknik analisis data menggunakan program komputer SPSS 20. Hasil penelitian kelas eksperimen tes awal nilai terendah 45 dan nilai tertinggi 85 dengan rata-rata 62,8333. Pada tes akhir nilai terendah 75 dan tertinggi 100 dengan rata-rata 86,8333. Sedangkan kelas kontrol tes awal nilai terendah 45 dan nilai tertinggi 85 dengan rata-rata 62,1667. Pada tes akhir nilai terendah 55 dan nilai tertinggi 90 dengan rata-rata 78,000. Hasil uji hipotesis menunjukan bahwa thitung > ttabel atau 3,721 > 2,002 pada tingkat kepercayaan 95%. Hal ini membuktikan bahwa Ha diterima dan Ho ditolak, dengan demikian strategi pembelajaran formasi regu tembak berpengaruh dalam pembelajaran mendramatisasikan teks drama siswa kelas XI SMK Negeri 2 Kayuagung Kabupaten Ogan Komering Ilir
