Abstract

Turbidity is one of the main water quality parameters in drinking water quality. One way to reduce turbidity levels is by filtration. The filtration unit in the water treatment plant must use appropriate media so that the processed raw water meets World Health Organization (WHO) standards. WHO states that the turbidity of processed water before disinfection is 1 NTU. This research was conducted to know the efficiency of filtration processing with various media in reducing the concentration of turbidity in raw water. This study used three types of media, namely 50% silica sand with a mesh size of 12-16 and 50% silica sand with a mesh size of 8-12 (C), 100% silica sand with a mesh size of 12-16 (K), and 100% silica sand in mesh size. 8-12 (B). Porosity value for each sample C, K, and B is 0.412; 0.423; and 0.388. The detention time at maximum discharge for samples C, K, and B was 3.6, respectively; 3.76; and 3.45 minutes. The flow rates used for media samples C, K, and B were 4125 L/s and 2500 L/s, respectively. The removal efficiency produced by the highest turbidity was obtained in medium C with values of 90.8% and 89.9%, respectively. Meanwhile, media B gave the lowest turbidity removal efficiency, namely 86.3% and 86.4%. The results of all variations of the media used have met WHO standards, where the processed results have produced turbidity concentrations of 0.25 - 0.32 NTU.

Abstract

Pengabdian kepada masyarakat ini bertujuan untuk memperkenalkan teknologi penyiraman tanaman otomatis berbasis mikrokontroler Espesif Sistem 32 kepada siswa-siswi SMKN 7 Kota Serang. Teknologi ini diharapkan mampu meningkatkan efisiensi pertanian, terutama dalam pengelolaan air di lahan pertanian. Kegiatan ini dilatarbelakangi oleh tantangan yang dihadapi petani dalam menjaga pasokan air yang memadai, terutama pada musim kemarau, serta kebutuhan akan penerapan teknologi otomatisasi dalam kehidupan sehari-hari. Metode yang digunakan dalam pengabdian ini meliputi ceramah, pelatihan, dan diskusi. Siswa diperkenalkan dengan komponen teknologi penyiraman otomatis, seperti sensor kelembaban tanah dan mikrokontroler, serta diberikan pelatihan langsung tentang perakitan dan pemrograman sistem tersebut. Dari hasil kegiatan, siswa menunjukkan antusiasme yang tinggi dan berhasil memahami pentingnya teknologi otomatisasi dalam meningkatkan produktivitas pertanian. Kesimpulannya, siswa-siswi SMKN 7 Kota Serang awalnya kurang familiar dengan teknologi otomasi, namun setelah kegiatan ini, mereka mampu mengaplikasikan ilmu yang didapatkan untuk memecahkan masalah penyiraman tanaman di lingkungan sekitar mereka. Untuk pengabdian berikutnya, disarankan agar siswa mendapatkan pelatihan lebih lanjut mengenai manajemen sistem otomatisasi dan cara menjaga keberlanjutan teknologi ini di lapangan.

Abstract

Sampah plastik menimbulkan permasalahan serius karena sulitnya terdegradasi oleh alam dan menimbulkan pencemaran pada lingkungan. Kehadiran Bank Sampah Seni Baru yang terletak di Kecamatan Kebayoran Baru, Jakarta Selatan, merupakan salah satu upaya mengurangi pembuangan sampah plastik. Hingga kini, Bank Sampah Seni Baru belum memiliki reaktor pengolahan sampah plastik khususnya reaktor pirolisis. Bank Sampah Seni Baru dalam operasional pengelolaannya melakukan pendekatan daur ulang sampah plastik kepada masyarakat sekitarnya melalui pemanfaatan sampah plastik menjadi bentuk kerajinan tangan dan lainnya. Tentu saja metode daur ulang ini pada suatu waktu akan menghadapi permasalahan yang sama karena hanya mengubah bentuk dari sampah plastik tersebut untuk sementara waktu. Atas dasar permasalahan ini, kegiatan ini bertujuan untuk memperkenalkan teknologi pirolisis sebagai bentuk daur ulang yang dapat mengubah sampah plastik menjadi fraksi cair yang memiliki sifat sebagai bahan bakar. Luaran dari kegiatan ini adalah menghasilkan reaktor pirolisis dan melakukan pelatihan teknis mengenai penggunaan reaktor pirolisis tersebut
