Abstract

Kolam retensi Ario kemuning adalah salah satu dari beberapa kolam retensi yang ada di kota Palembang yang terletak di Jl Swadaya Lorong Perikanan IV Kelurahan Talang Aman. Kolam retensi ini berada dalam satu sistem dengan sistem saluran sungai bendung. Kolam Retensi Ario kemuning berada diatas tanah dengan luas + 14,977m2. Kondisi kolam retensi Ario kemuning termasuk dalam kondisi daratan rendah dan daerah yang berawa-rawa, dengan topografi relatif datar dan merupakaan daratan rendah. Pada setiap hujan deras, genangan air sering terjadi di daerah saluran masuk kolam retensi Ario Kemuning, dimana genangan air yang terjadi menyebabkan rusaknya jalan, dan juga terhambatnya pengguna jalan kaki. Berdasarkan hasil penelitian ini kolam retensi Ario kemuning melalui dimensi saluran inlet dengan nilai h = 3 meter, tidak lagi dapat menahan Q Inflow = 5,060 m3/det. Untuk dapat menahan debit air yang masuk saluran inlet kolam retensi tersebut mesti diperbaiki nilai h saluran tersebut begitu juga dengan saluran outletnya mesti dibersihkan sedimen dan penumpukan sampah agar air yang mengalir disaluran tersebut lancar. Kolam retensi Ario Kemuning tidak dapat lagi menampung, air apabila hujan selama lebih dari 41,4 menit dikarenakan kurangnya perawatan dari instansi terkait, sehingga menyebabkan terganggunya sistem kerja dari kolam retensi tersebut. Saluran inlet dan saluran outlet tidak dapat menampung air masuk kedalam kolam dan keluar kolam dikarenakan adanya sedimen dan penumpukan sampah sehinga menganggu aliran.

Abstract

One of problems that often occur in Gresik Regency in Gresik City is Floods. As a result of flood, the biggest impact occurred in the Districts of Cerme, Benjeng, Menganti, and Balongpanggang. The research has a purpose, namely, to find out what factors cause flooding in the South Gresik City Region. The methods used are interviews and questionnaires. Interviews were used to determine the type of flood mitigation that was suitable for the southern Gresik City area. While the questionnaire was given to determine the appropriate mitigation according to the existing conditions in the area or the factors causing flooding in the southern Gresik City area. Mixed Methods were used to collect data with qualitative and quantitative data types. Qualitative data was conducted through direct observation and interviews. While the quantitative data was obtained from questionnaire results. From the results of the analysis using Nvivo 12 plus©, the cause of flooding that often occurs in Gresik City is caused by the overflow of the Lamong River. Rather than that caused by the river experiencing siltation. This causes runoff to overflow. Mitigation is one thing that can be done when there is a flood in the southern Gresik City area. Analytic Hierarchy Process (AHP) is a river improvement and regulation system which includes benchmarks with the highest yield of 0.558. The best alternative is River improvement, namely river dredging with a weight of 0.404.

Abstract

Traffic accidents are one of the biggest causes of death in Indonesia. An accident-prone location is a highaccident rate with the incidence of repeated accidents in a relatively the same space and period caused bya specific cause (Pd-T-09-2004-B). Based on data from Lakalantas Polres Ogan Ilir (2018), trafficaccidents in Ogan Ilir Regency are ranked second below Palembang among all districts in South SumatraProvince, with 257 incidents, 101 deaths and 394 injuries. On the Palembang-Indralaya road segment in2018, there were accidents with 80 cases, and 27 people died. For this reason, it is necessary to analyzethe accident-prone points (Black spot) on the Palembang - Indralaya National Road Section. The dataused to determine the Black spot point is traffic accident data within four years using the AccidentEquivalent Number (AEK) method. The analysis of accident data from 2015 - 2019 contained 14 Blackspot points on the Palembang - Indralaya national road with various levels of victim injuries.

Abstract

Flow discharge data must be available in a time series and accurate manner, so there should be no empty periods. Therefore, a model is needed that can reconstruct or estimate the flow discharge of the empty period stochastically. One way to solve this problem is by filling in data or data generation.The philosophy of data is to create new data sets based on generally incomplete or short historical data to obtain longer and more complete data. The new complete and long data is made with properties as well as short data as the source (Sri Harto and Sudjarwadi, 1989). Model ARIMA represents three modeling namely of autoregressive model (AR), moving average (MA), and autoregressive and moving average model (ARMA) which has characteristic of two models. First stage modeling ARIMA is testing stationary data, identification model, estimation parameter model and forecasting. Data used in this model Arima is discharge complete station Maribaya DAS Cikapundung Hulu if from years 1978 from the research. Results ARIMA model produces correlation values of 0.657 with a target value of 1. For the absolute relative error rate (KAR) and the average error rate (RMS) each produces a value of 0.0052 and 0.017 with a target value of 0. The ARIMA model can be used to fill in, generate discharge data and can be used to predict future flow rates. In discharge forecasting, the ARIMA model is only able to predict discharge accurately in a short time span. For long-term forecasting, the resulting forecast will tend to be flat (flat/constant).

Abstract

Qualitatively, according to the waste in the construction sector in Indonesia, it is quite large, namely 57% when compared to the manufacturing industry which has 26% waste, the inefficiency in megaprojects is caused, among others, by too many design changes, low work expertise, delays in decision making, coordination that is not good between the parties involved, weak planning and control, delays in material delivery, and inappropriate work methods. Lean construction concept is used to eliminate waste and maximize value for users or customers. In addition, he said that the framework is a step-by-step guide in the form of a suitable guide to facilitate the implementation of the lean construction concept because the lean construction concept is a process-based concept. The purpose of this study is to identify critical factors that support and hinder the implementation of the lean construction concept in mega projects in Indonesia. In this study, a systematic literature review was used to examine the supporting factors and inhibiting factors for the implementation of lean construction. After conducting a literature review, four main supporting factors were obtained, namely managerial, labor, organizational and external. The managerial sub-factors are management commitment and Leadership Management. In addition, it was also found that the barrier factors from the implementation of lean construction were managerial, workforce, company/project organization and external. The supporting sub-factors of managerial are management commitment, management leadership, Management is unable to change existing construction concepts, Lack of training for contractors and subcontractors, misconceptions about lean construction method

Abstract

Hyacinth plant in Latin terms called Eichhornia crassipes is an aquatic plant that until now is still considered a pest of the gadfly and is very difficult to destroy. This is because hyacinths have very fast growth properties and have good survival. Hyacinth is an aquatic plant that absorbs a lot of water, causing a lot of surface water to decrease a lot to reach four times when compared to an open water surface and this plant can also cause siltation in rivers or swamps, closures in river grooves or other swamp areas. But on the other hand, it shows that hyacinth plants can be used for home industry and also a very high fiber content. If hyacinth is burned, it will produce ash containing silica (SiO2) which can be used to add material to the concrete mixture. This study aims to find out the best variation in the addition of hyacinth ash so as to produce the most optimal compressive strength by adding hyacinth ash starting from 6%, 7.5%, 9%, 10.5%, 12%, 13.5% and 15% to the weight of cement in karaktristic concrete Fc'= 22 Mpa and the concrete compressive strength test is carried out at the age of 28 days. From the test results, it can be seen that the compressive strength of concrete at the age of 28 days obtained the most optimal conditions occurred in the addition of hyacinth ash of 10.5% in concrete mixtures with the resulting cartrictic compressive strength of 25.46 Mpa, this condition led to an increase in the compressive strength of concrete as large as 13.86% of normal concrete.
