The purpose of this study was to Analyze the characteristics of theaggregates used in concrete mixtures and analyze how muchincrease in compressive strength of concrete with a variation ofnickel slag substitution 0%, 5%, 15%, 25% compared with normalconcrete. The characteristics of the material examined are watercontent, sludge content, specific gravity and absorption, volumeweight, abrasion with los angeles machines, and filter analysis.While the large increase in compressive strength of concrete can betested at the age of 7 days, 14 days, 28 days and 35 days. From the results of the analysis of the characteristics of nickel slagwaste in concrete mixes meet the test standards in concretemixtures, with a moisture content of 0.86%, sludge content of 0.44%,specific gravity of 2.94 gr / cm3, volume weight of 1.76 gr / cm3,abrasion 36.07%. And a large increase in compressive strength ofconcrete with a variation of nickel slag substitution of 0%, 5%, 15%,25% compared to normal concrete is increasing. The highestpercentage increase in concrete compressive strength is found inconcrete compressive strength between a variation of 15% with avariation of 25% at 14 days concrete age, with a percentage increasein value of 13.13%.
Research on Aepodu Weir Sediment Transport Analysis in South Konawe District, based on observations in the field, Aepodu Weir hasa sediment buildup that has now exceeded the height of the weirlight house. The purpose of the study was to analyze the magnitudeof Aepodu river flow and to analyze the amount of sedimenttransport that occurred in the Aepodu dam. The method used todetermine the amount of bed load transport uses stchoklitscht, whilefor transporting suspended load using forcheimer.The results of the analysis of the average flow of the Aepodu riverwere 3,604 m3/ second. Sediment transport that occurs in Aepoduweir is Bedload transport (Qb) of 291625.771 tons / year, andsuspended load transport (Qs) of 16972,423 tons / year, so that thetotal sediment transport (QT) is 308598,194 tons / year.
Concrete is one of the most widely used building materials today interms of physical construction. Concrete is made from a mixture offine, coarse aggregate, cement, and water with a certain ratio, aswell as materials that are usually added to the concrete mixtureduring or during mixing, to changing the properties of concrete tomake it more suitable in certain jobs and more economical, can alsobe added with certain other mixed materials as needed if deemednecessary. Seashells can be used to mix concrete. This study aims todetermine whether the addition of shells aggregate shells in aconcrete mixture can affect the mechanical properties of concrete.The specimens used are in the form of cubes with a size of 15cm x 15cm x 15 cm, consisting of additional concrete coarse and fineaggregate with shell substitution percentage of 0%, 15%, 20% with atotal sample of 45, with the planned concrete quality of K225. Theuse of sea shells in increasing the compressive strength of concrete isbetter used as fine aggregate than coarse aggregate. The use of seashells as a substitute for fine aggregates achieves maximum resultsat 20% composition.

Indonesia is a large country that is widespread with it’s islands and isa country traversed by the Equator, so sea transportation has animportant role to play in connecting one area to another, consideringthat Indonesia has a very wide ocean. One of the means of seatransportation that is widely used by the community is the ferry. Ferryis a type of sea transportation that can be used as passenger andgoods transportation using certain routes or routes. With theexistence of the Ferry port, it can increase the acceleration ofdevelopment in the area, especially Amolengo Village, KonaweSelatan Regency.The Amolengo ferry port is a port that serves the crossing ofpassengers and goods that connects the South Konawe mainland andits surroundings with Buton Island, where the destination port is Pureport. The quality of good service provided is one of the determiningfactors for the success of the company. The research method isarranged by interviewing respondents by answering the questions onthe questionnaire. The analysis was performed using ImportancePerformance Analysis (IPA) and the Customer Satisfaction Index (CSI).The results of this study indicate that the consumer satisfaction indexon the performance of the Amolengo - Pure Ferry Port, SoutheastSulawesi Province is 84.6% and is in the range 0.81 - 1.00 indicatingthat consumers are very satisfied with the service quality of theAmolengo - Pure Ferry Port, Southeast Sulawesi Province.
Productivity is one of the fundamental factors that influences the ability of performance in the construction industry. Increasedproductivity will reduce work time, and will reduce costs, especiallylabor costs so that the minimum labor cost is obtained (labor costs)to get competitive prices both for auction and implementation. Thepurpose of this study is to analyze the labor productivity time incompleting 1 m2 of masonry bricks and to analyze the productivityvalue of brick masons in completing work activities in the constructionproject of the Mandala Wangi 2 female dormitory. The results showedthat the time required to complete 1 m2 of brick laying work was 41.13minutes on average. The productivity of the artisans working on the 1stfloor is an average of 1.45 m2/hr. Meanwhile, the productivity ofcraftsmen working on the 2nd floor is an average of 1.47 m2/hr.
Performance Evaluation is a system and how to determine the work ofindividuals, employees, work units and organizations as a whole thatare used to ensure the achievement of goals and objectives. The purpose of this study is to analyze the level of importanceand customer satisfaction on service and position of each variablewhen associated with performance indicators and service usersatisfaction in the terminal of Haluoleo Airport cargo.
