In the execution cycle of a construction project often found a divergence varians especially withrespect to time and costs, which in detecting the occurrence of a deviation of the project is oftencarried out an evaluation of the performance of the results that have been achieved both on timeand cost. One method that is most frequently used in evaluating the performance of the cost andtime that the methods Earned Value Management (EVM), but in the study of analysis methods EVMcan be concluded that the assumptions used only linear and static the estimation of the time andcost of the project from performance has been generated just shows the estimated value of which isrigid and not dynamic, where as if the result of the estimated project cost and time performanceshows one possible course. Therefore, the purpose of writing this article which is to carry out adevelopment model of performance measurement time and cost of the project by analyzing acombination of uncertainty dymanic against time and cost of the project, which will be used incombination by entering the numbers uncertainties optimistic, enable / ideal and pessimism aboutthe estimated time performance and future costs at the time of the evaluation process is done(Freeze time). From the study results of the analysis conducted can be formulated basic equation inthe form of indicators that can be formulated to predict total project time and cost of the threeconditions, namely optimistic pessimist and ideal and analysis to the level of probability methodsnormal distribution to predict time and totalcost of completing a project construction

Analysis of public transport tariffs is one of the supporting factors for public transportation for the general Makassar community. Especially people who use transportation transportation services on the Central Market route - Minasa Upa or vice versa. The purpose of this research is to obtain a detailed description of the analysis of the costs of the Central Market public transport route - Minasa Upa in Makassar City and analyze public transport fares on Central Market routes - Minasa Upa and from Minasa Upa - Central Market. The data collection method used in this study was conducted by conducting interviews and questionnaire distribution to the public transportation management (Angkot) routes of the Central Market-Minasa Upa. The calculation results of Central Market transport rates - Minasa Upa which consists of two types of vehicles, namely, Suzuki Carry 1500 cc produces a basic tariff for public transportation of Rp. 4000, - / Route and Student Transportation Tariff of Rp. 2600, - / Route, while for the type of Daihatsu Grand Max 1500 cc, the basic tariff for public transportation is Rp. 5000, - / Route and student transportation tariff of Rp. 3400, - / Route

In the planning concept for the housing project, PT Baruga Asri, the Blaithai area, still uses a modular septic tank and is still conventional. Meanwhile, there are alternative choices for the type of Septic tank as a fecal treatment facility which are widely available in the market. The research method uses primary data, with sources of RAB, and Makassar City Work Unit Price Analysis. As well as secondary research methods with sources, from relevant books, and important data about the project such as price lists and wages. It can be concluded that among all Balithai Land housing developments by following the RAB reference for Bukit Baruga Asrinusa housing in the Balithai Land area and AHSP (Work Unit Price Analysis) Makassar city, sanitation work items are one of the work items that can be broken down in terms of the costs involved. also eat up a large budget, even though there are actual work items that cost more. And there was a difference in sanitation work items between the main design and alternative designs of Rp. 148,718.00 and there was 1 alternative design that was raised to replace the existing design currently used, namely by replacing the use of Septic Tank buis concrete Ø80 (4 stacks 2.0 m high) + Cover + Infiltration + 2.5" ventilation pipe with a septic tank with bio capacity of 3-5 0 people. Thus saving the cost of the Bukit Baruga Asrinusa housing development project in the Balithai Land area phase 2. From Rp. 7,025,788.31 to Rp. 6,877,070 ,15.

Project work delays often occur due to differences in site conditions, design changes, weather influences, and planning errors. The problem faced is the project duration, where if the project duration is accelerated or crashes, there will be several options to cut the project duration. This is the problem that becomes the topic of the thesis/journal, namely "Analysis of Project Acceleration with the Crashing Method with Alternatives for Adding Manpower and Additional Working Hours in Drainage Works". The author uses the primary method, with sources of RAB, Time Schedule, working drawings and analysis of city unit prices. As well as secondary research methods with sources, from relevant books, and project data such as price lists and wages. From the results of the study it can be concluded that the total wages of workers under normal conditions is IDR. 16,864,000.00 with the duration of project work for 30 working days. From the results of the analysis in this study, the total wages of workers with alternative labor additions of IDR. 19,672,000.00 with the duration of project construction work for 25 working days or 15.15% faster than the normal duration. Meanwhile, the total wage for workers with the alternative of additional working hours (overtime) is IDR. 25,052,300.00 with the duration of the project construction work for 25 working days or 15.15% faster than the normal duration. A more economical alternative to completing the project is the addition of manpower because it saves IDR. 2,228,000.00 from additional working hours (overtime), from normal wages.

Land transportation, especially public transportation between cities, is very important in carrying out oneof its main functions, namely as a means of transporting people to carry out their daily activities wherethe services provided are expected to be carried out quickly, safely, comfortably, cheaply and efficiently.The puIDRose of this study was to determine the value of vehicle operating costs (BOK) for the Siwa-Palopo route using data collection methods by means of surveys and direct interviews with publictransportation operators. Based on the analysis of research data from the results of the IntercityTransportation Within the Province (AKDP) route Siwa - Palopo, the following conclusions were drawn;Mini Bus Vehicle Operating Costs with a BOK value of IDR 158,730,866, - / Year or IDR 2,701.71, - / Km.The income of Mini Bus Vehicle Owners is IDR 207,360,000 / Year or IDR 3,529.41 / Km. From the resultsof the analysis of the data calculations above, it can be seen that public transportation owners get a netprofit of IDR. 48,629,134.1,-/year or IDR. 827.70,-/km. Where the income obtained by the transportationowner is greater than the Vehicle Operating Cost.
