ANALISIS PERHITUNGAN AIR LIMBAH DOMESTIK DI KELURAHAN DELITUA BARAT

Introduction

Analisis perhitungan air limbah domestik di kelurahan delitua barat. Analisis perhitungan debit air limbah domestik di Kelurahan Delitua Barat berdasarkan proyeksi penduduk untuk perencanaan sistem pengolahan limbah yang optimal dan berkelanjutan.

Abstract

Pertumbuhan jumlah penduduk dan perkembangan wilayah di daerah perkotaan maupun pinggiran kota semakin memperbesar volume kebutuhan air bersih, yang secara otomatis meningkatkan jumlah limbah cair domestik. Menurut Anwar (2018), timbulan air limbah domestik dapat mencapai 60–80% dari total kebutuhan air bersih, sehingga semakin tinggi konsumsi air bersih, semakin besar pula air limbah yang dihasilkan. Hal ini menunjukkan pentingnya perhitungan timbulan air limbah yang berbasis pada analisis kebutuhan air bersih. Penelitian ini bertujuan untuk menganalisis perhitungan debit air limbah domestik sebagai dasar perencanaan sistem pengolahan air limbah yang optimal dan berkelanjutan. Metode yang digunakan meliputi pengumpulan data primer serta analisis proyeksi jumlah penduduk dengan pendekatan aritmatik dan geometrik dan analisis perhitungan debit air limbah. Hasil proyeksi menunjukkan bahwa jumlah penduduk akan meningkat dari 8.834 jiwa pada tahun 2024 menjadi sekitar 11.237 jiwa pada tahun 2034. Berdasarkan proyeksi tersebut, dihitung kebutuhan air bersih serta estimasi debit air limbah domestik menggunakan standar konsumsi air 80 liter/orang/hari. Debit air limbah dihitung sebagai 70–80% dari kebutuhan air bersih. Perhitungan juga mencakup debit puncak dan debit minimum sebagai dasar perencanaan sistem pengelolaan limbah

Review

This study, "ANALISIS PERHITUNGAN AIR LIMBAH DOMESTIK DI KELURAHAN DELITUA BARAT," addresses a highly relevant and pressing issue concerning urban and suburban development: the management of domestic wastewater. As populations grow and demand for clean water increases, so too does the volume of wastewater, creating an urgent need for effective planning. The research is motivated by the critical link between clean water consumption and wastewater generation, aiming to analyze domestic wastewater discharge calculations as a fundamental step towards designing optimal and sustainable wastewater treatment systems. This foundational work is crucial for municipal planning and environmental sustainability in rapidly developing areas like Delitua Barat. The methodology employed by the researchers is straightforward and appropriate for the stated objective. It involves primary data collection, population projection utilizing both arithmetic and geometric approaches, and subsequent analysis to calculate wastewater discharge. A key strength lies in its explicit use of standard consumption rates (80 liters/person/day) and a clear ratio for wastewater generation (70-80% of clean water demand), ensuring a transparent basis for calculations. The study projects a significant population increase from 8,834 individuals in 2024 to approximately 11,237 by 2034. Based on these projections, the paper meticulously calculates clean water demand and estimates domestic wastewater discharge, including critical peak and minimum flow rates, which are essential parameters for engineering design. The findings of this research provide a valuable basis for the future planning and development of wastewater management infrastructure in Kelurahan Delitua Barat. By offering clear projections of population growth and subsequent wastewater volumes, the study furnishes local authorities and planners with concrete data necessary for informed decision-making regarding treatment system design and capacity. While the abstract presents a robust calculative approach, future work could potentially benefit from incorporating more granular data on water usage patterns or socio-economic factors that might influence per capita consumption. Nevertheless, this paper makes a significant contribution by laying the groundwork for sustainable wastewater management, emphasizing the importance of accurate initial calculations for long-term environmental and public health benefits.
