Abstract

Kebutuhan material beton yang ramah lingkungan semakin meningkat seiring dengan tuntutan pembangunan berkelanjutan, khususnya dalam pemanfaatan limbah organik seperti serat sabut kelapa. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan serat sabut kelapa sebagai bahan tambah terhadap kuat tekan beton mutu K-275. Metode yang digunakan adalah eksperimen laboratorium dengan variasi penambahan serat sabut kelapa sebesar 1%, 2%, dan 3% dari berat semen. Pengujian dilakukan pada benda uji berbentuk kubus dengan umur perawatan 7 dan 28 hari sesuai standar SNI 1974:2011. Hasil penelitian menunjukkan bahwa penambahan serat sabut kelapa 1% memberikan peningkatan kuat tekan optimum dibandingkan beton normal, yaitu mencapai sekitar 288,20 kg/cm² pada umur 28 hari. Sementara itu, penambahan 2% masih menunjukkan peningkatan ringan, sedangkan 3% menyebabkan penurunan kuat tekan akibat berkurangnya workability dan ikatan pasta semen. Kesimpulannya, serat sabut kelapa dapat dimanfaatkan sebagai bahan tambah alternatif pada beton K-275 dengan kadar optimum 1%. Rekomendasi penelitian ini adalah penggunaan variasi serat di bawah 2% untuk menjaga performa mekanis beton. Implikasi penelitian ini mendukung pengurangan limbah organik serta pengembangan material konstruksi yang lebih ramah lingkungan dan berkelanjutan.

Abstract

High intensity rainfall that occurs can cause puddles if the condition of the drainage system is not well maintained. The development of Pontianak City Infrastructure has resulted in land use changes that was originally in the form of vacant land converted into residential areas or other economic activities. The existing condition of the drainage channel at M. Sohor Road is not able to accommodate rainwater discharge in the rainy season. In the existing conditions for land use, there is no rainwater catchment area. The management of floods with arranging the drainage system has been ineffective so we need an environmentally drainage system arrangement concept.  Identification of the hydrological and hydrolic conditions that exist in the catchment area of the M. Sohor channel is required. The hydrological analysis in this study includes testing the consistency of rainfall data in Pontianak City, selecting a rain distribution that matches the rainfall data pattern, calculating the time concentration, rainfall intensity and the total discharge from domestic discharge and design discharge of 2, 5, 10 years. The hydraulic analysis in this study includes the design of a channel cross section design as a channel normalization plan. The total flow discharge in M.Sohor channel for a 2-year return period is 2.22 m3/s, a 5-year return period of 2.75 m3/s and a 10-year return period of 3.09 m3/s. Environmental insight drainage can be done by planting shrub plants that can reduce air pollution such as Croton and Bougainvillea, arranging M. Sohor Road to be friendly with pedestrians controlling excess rainwater discharge caused by the rain process through rain water harvesting techniques.
