Abstract

Noise is unwanted sound, which can impair the health and comfort of the environment, have a source and propagates through a medium. Provincial Civil Service Agency of Southeast Sulawesi’s Office is located at the intersection of Drs. H. Abdullah Silondae Street, Laute Street and Malik Raya street with dense vehicle traffic, which Drs. H. Abdulah Silondae Street is the route of public transportation to the downtown to UHO Campus. The purpose of this research is to analyze the noise level due to the activities of the traffic in the area of Provincial Civil Service Agency of Southeast Sulawesi’s Office, analyzing the annoyance perception employees due to the traffic noise and the characteristics of respondents, and analyze the influence of noise level against the employees annoyance level. Data analysis of obtained that the average noise level in the area of Provincial Civil Service Agency of Southeast Sulawesi’s Office has passed the quality standards of noise to the office area. The perception of employees due to interference noise is 44% of the respondents who stated not bothered by noise in the area, 24% of respondents who stated a bit distracted, 24% stated quite disturbed, and 8% declared disturbed. As for the noise have significant influence towards employees level of annoyance.

Abstract

This study aims to evaluate the current performance of urban transportation within the province and analyze the need for urban transportation modes within the province. The data analysis technique uses mathematical equations with the help of Microsoft Excel Software. The observation point is at the Baruga Terminal of Kendari City. The results showed that the return trip time of the 8 study routes was only 6 routes that met World Bank standards, namely Torobulu, Andoolo, Lainea, Tinanggea, Palangga and Motaha routes. For vehicle frequency, only 4 routes meet World Bank standards, namely Bambaea, Lainea, Tinanggea and Palangga routes. From the aspect of the loading factor, the highest is on the Torobulu, Lainea and Palangga routes, while the lowest is on the Boepinang route. From the aspect of time difference, none of them meet the World Bank's standard values. From the aspect of cycle time, only 1 route does not meet the standard, namely the Boepinang route. The need for city-in-province transportation modes at the Baruga Terminal has not met the standard because the number of vehicles operating is far less than the number of vehicles set by the Southeast Sulawesi Provincial Transportation Service.

Abstract

The durability of the road flexural pavement structure is largely determined by the performance of each layer. One of these factors is the strength and resilience of the subbase. Compaction in accordance with applicable standards will produce roads with good quality so that the road life is longer and there is less damage. The purpose of this study is to analyze the carrying capacity using CBR, the value of the field density with the sand cone test and the correlation of the CBR value and the Sand cone value of the B grade foundation layer on the Tugu Munajah network. The research method used is laboratory and field testing combined with a descriptive statistic approach. The results of the study indicate that the carrying capacity using the CBR amounted to 55.02% <60%, the density value field with sand cone test of 72.50% <90%. Correlation of CBR and Sand cone value at the base layer (sub base course) is very strong at 0.998.

Abstract

Tonasa cement, Bosowa cement, and Tiga Roda cement have diffenrence characteristic from procedure to produce and composition of ingredients, the difference are probably reach the diffenrence respond or effected from three brands are mixed from admixture to be a mix concrete. One of the commonly admixture and easy to find is Damdex Brand that can increase the strengthness of the concrete. The aimed of this investigation to analyse the effect of admixture (Damdex) variation toward concrete compressive strength by comparison the cement brands.The methodology of this investigation is experiment method or material test in laboratory. The concrete compressive strength will calculated during 28 days age, after giving an admixture (0%,1%, 1,5%,2%, 2,5% dan 3%) with different brands cement variation,but composition of Concrete such Agregat and Water are same from each treatment. The sample from each treatment totally 3 tested samples. The result of this investigation, Tonasa cement is increase with concrete compressive strength from highest of admixture (Damdex) from admixture level is 2% which gain compressive strength 385,24 Kg/cm2 or increasing amount 23,52% from normal concrete compressive strength. Bosowa brand is increase with concrete compressive strength from the highest admixture ( Damdex) the level is 2.5 % with compressive strength gain is 338,00 Kg/cm2 or increase amount 10,15% from Normal concrete compressive strength.Compressive strength of Tiga Roda brand also gain increase from admixture with highest level is 3% which 354,35 Kg/cm2 compressive or increase amount 18,60% from normal concrete compressive strength

Abstract

Anduonuhu Village is one of the areas in Kendari City that has been affected by flooding in the last 10 years. Data of fload events occurred in 2013 and 2017. Based on the Data of the Kendari City Enfironmental Status Report in 2010, the distribution of potential areans prone to flooding in the city of Kendari, Anduonuhu sub-district was ranked 2 (two) with an area of 359.817 ha. The purpose of this sudy is to analyze extreme rainfall over the past 10 years, to analyze the factors that cause flooding and the priority of handling the anduonuhu river. In analyzing, the autors collect data by conducting field surveys and collecting data on gydrology, tophography and land use at the study site. The results of data analysis show that extreme rainfall in the last 10 years at the study site occurred in 2013 amounted to 191.6 mm. factors causing flooding at the study site were caused by extreme rainfall inundating the Anduonuhu watershed and land use change. The priority handling is done by modeling scenarios with normalization and river embankments.

Abstract

Indonesia is a large country that is widespread with it’s islands and is a country traversed by the Equator, so sea transportation has an important role to play in connecting one area to another, considering that Indonesia has a very wide ocean. One of the means of sea transportation that is widely used by the community is the ferry. Ferry is a type of sea transportation that can be used as passenger and goods transportation using certain routes or routes. With the existence of the Ferry port, it can increase the acceleration of development in the area, especially Amolengo Village, Konawe Selatan Regency. The Amolengo ferry port is a port that serves the crossing of passengers and goods that connects the South Konawe mainland and its surroundings with Buton Island, where the destination port is Pure port. The quality of good service provided is one of the determining factors for the success of the company. The research method is arranged by interviewing respondents by answering the questions on the questionnaire. The analysis was performed using Importance Performance Analysis (IPA) and the Customer Satisfaction Index (CSI). The results of this study indicate that the consumer satisfaction index on the performance of the Amolengo - Pure Ferry Port, Southeast Sulawesi Province is 84.6% and is in the range 0.81 - 1.00 indicating that consumers are very satisfied with the service quality of the Amolengo - Pure Ferry Port, Southeast Sulawesi Province.

Abstract

Concrete is one of the most widely used building materials today in terms of physical construction. Concrete is made from a mixture of fine, coarse aggregate, cement, and water with a certain ratio, as well as materials that are usually added to the concrete mixture during or during mixing, to changing the properties of concrete to make it more suitable in certain jobs and more economical, can also be added with certain other mixed materials as needed if deemed necessary. Seashells can be used to mix concrete. This study aims to determine whether the addition of shells aggregate shells in a concrete mixture can affect the mechanical properties of concrete. The specimens used are in the form of cubes with a size of 15cm x 15 cm x 15 cm, consisting of additional concrete coarse and fine aggregate with shell substitution percentage of 0%, 15%, 20% with a total sample of 45, with the planned concrete quality of K225. The use of sea shells in increasing the compressive strength of concrete is better used as fine aggregate than coarse aggregate. The use of sea shells as a substitute for fine aggregates achieves maximum results at 20% composition.
