Abstract

The capacity of drainage can overflow due to inadequate conditions and high rainfall intensity. Several incidents in Bekasi City due to poor drainage resulted in inundation of water on the roads which resulted in damaged roads and flooding in residential areas. Several previous studies have discussed the evaluation of the drainage system using the analytical method hydrology in modeling water discharge. In most cases, the minimum capacity of the drainage canal is caused by the high intensity of rain, so the research focuses on the volume of drainage and the intensity of the rain. However, based on observations and interviews with the cleaning service, it turns out that many drainage channels are in a non-optimal condition, where there is a lot of garbage and sedimentation that hinders the flow of water when it rains. This study combines hydrological analysis modeling with drainage channel conditions whose real time data is obtained by using sensors through the internet of things (IoT). IoT devices have been able to send data well in the cloud, by combining rainfall data and then predictive modeling using RNN LSTM with training model parameters used are two layers and 20 cells with each layer given a Dropout layer with a probability of 10%. In the metric evaluation, four functions are used, namely mean squared error, Mean absolute, Nash-Sutcliffe Efficiency and Coefficient of Determination. The model has been able to see the occurrence of an increase or decrease in height and discharge. However, if you look at the results of metric calculations, the predictions generated by the model are not very good.

Abstract

Pondasi merupakan bagian dari struktur bawah (sub structure), mempunyai peranan penting dalam memikul beban struktur atas sebagai akibat dari adanya gaya-gaya yang terjadi pada struktur atas (upper structure) seperti gaya angin, gaya gempa maupun berat struktur itu sendiri. Tujuan dari penelitian ini untuk menghitung penurunan (settlement) pondasi bored pile dan menghitung kuat dukung pondasi bored pile berdasarkan hasil standar penetration test (SPT). Metode perhitungan untuk menghitung penurunan menggunakan metode Vesic (1970) dan Software Plaxis. Metode perhitungan untuk menghitung kuat dukung pondasi menggunakan metode Meyerhoff (1956), metode Reese & Wright (1977) dan software Plaxis. Berdasarkan perhitungan Vesic (1970) didapat penurunan sebesar 20,83 mm dan pada Software Plaxis didapat penurunan sebesar 12,32 mm. Berdasarkan data SPT yang diperoleh hasil perhitungan menggunakan metode Meyerhoff (1956) Qu sebesar 1627,8 ton, dengan metode Reese & Wright (1977) Qu sebesar 1276,4 ton dan dengan software Plaxis Qu sebesar 1300 ton. Dari hasil perhitungan penurunan didapat software plaxis lebih mendekati hasil axial test dibanding metode Vesic(1970) begitu pula untuk perhitungan daya dukung pondasi metode Reese & Wright (1977) lebih mendekati hasil axial test dibandingkan dengan metode Meyerhoff (1956) dan software plaxis.

Abstract

Sawdust waste from the furniture industry should be considered. Nowadays, the increased demand for furniture is in line with the increase in sawdust waste produced. Therefore, it is necessary to make use of sawdust to protect environment. An alternative use is the addition of sawdust as the concrete mixture. Cellulose and hemicellulose compounds are compounds contained in wood powder, where these compounds can provide additional bonding between particles in the cement and sand mixture in concrete. Therefore, concrete can be stronger as well as more water resistant, hence it can be used for a specific purpose in constructions. This study aims to analyze the compressive strength of concrete due to the addition of sawdust as an organic fiber in the concrete mixture with the percentage of 0.25%, 0.50%, 0.75% and 1% as substitution of sand. Organic fibers as additives in concrete are being developed until recently. The proposed concrete was 25 MPa quality. Result showed the increase in the compressive strength of concrete by 0.98% in 1% wood powder mixed at 28 days of concrete age.
