Abstract

Kurangnya peran serta warga atau masyarakat RW 02 Ciwaruga, Kabupaten Bandung Barat dalam pengelolaan sampah walaupun telah memiliki Bank Sampah Cempaka 2, yang dibentuk sejak tahun 2016. Metode pelaksanaan kegiatan PKM ini  disesuaikan  dengan  kondisi dan waktu kegiatan Bank Sampah dengan langkah-langkah melakukan kunjungan dan diskusi dengan kader penggiat bank sampah, memotret dan mensosialisasikan tingkat keberhasilan bank sampah dilihat dari manfaat secara sosial dan ekonomi, serta merumuskan penyuluhan dan mempersiapkan berbagai media sosialisasi. Perilaku memilah sampah berpotensi untuk ditumbuhkan sebagai gerakan massal dan adanya Bank Sampah, secara ekonomi, sangat membantu dalam menciptakan pekerjaan dan menambah penghasilan masyarakat RW 02 Ciwaruga. Kata Kunci: Bank Sampah, Dampak Sosial, Ekonomi, Memilah Sampah

Abstract

Abstract: This study aims to obtain more accurate external air pressure values ​​by applying the Van der Waals equation of state for a Boyle's Law experiment. Pressure data taken from a column of air trapped in a U-tube were analyzed using the ideal gas model and the Van der Waals model. The research findings indicate that the Van der Waals model provides external air pressure values ​​closer to the actual value with a relative error of 0.40%, compared to the ideal gas model, which has a relative error of 10.19%. Therefore, the use of the Van der Waals equation is recommended to improve the accuracy of the Boyle's Law experiment. Based on the research results, it can be concluded that the Van der Waals equation provides a higher level of accuracy than the ideal gas model in determining external air pressure in the Boyle's Law experiment.   Keywords: Boyle's Law, Ideal Gas, Van der Waals Equation, Atmospheric Pressure, Laboratory Experiment.
