The characteristics of night ship passengers are dominated by men, the average age of passengers is 20-25 years with a percentage value of 64%, the most travel destinations are Muna Island and the dominant service users have student jobs, while the analysis results are seen in the value of 0.66- 0.8, this means that the overall CSI score for performance appraisal is 1.96 with the criteria for the value of each indicator, service users are very satisfied with the performance of night ship services on the Kendari - Raha route, Southeast Sulawesi Province. The perception of service users towards night boat services on the Kendari - Raha route as a whole with an average value of 3.5 for performance and 3.1 for satisfaction. This can be seen in the quadrant A diagram in the Cartesian diagram, which means that the service elements are very good and provided very well.

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.

This study aims to analyze the degree of saturation of the signaled intersection at the intersection of PLN Wua-Wua Kendari, the longqueue condition based on the Manual Capacity Road Indonesia(MKJI, 1997) method with direct measurement in the field, trafficdelay condition, and predict the performance of PLN intersectionWua- Wua at 5 and 10 years to come. Data analysis techniques usemathematical equations by using Manual Capacity Method ofIndonesia (MKJI, 1997) with the help of Microsoft Excel. Trafficvolume surveys and queue lengths are carried out together for 15minutes each time for 12 hours of measurement. The long queuingcondition based on MKJI 1997 method on the east approaches 42,62meters, west approach 79,5 meter, North approach 47,1 meter andSouthern approach 52,4 meter with average queue length 55, 4meters. While based on the calculation directly in the field obtainedvalue on the approach of the East of 33.51 meters, Westernapproach of 39.23 meters, Northern approach of 41.53 meters,South approach of 58.05 meters, with an average queue length of43, 08 meters. The traffic delay on the Eastern approach was 56.2seconds / smp, Western approach of 84.1 seconds / smp, Northapproach of 64.1 seconds / smp, and Southern approach of 69.0seconds / smp. Predicted traffic volume for the next 5 years for theEastern approach of the DS value of 0.94 with the LOS E, the westernapproach to the DS value of 1.29 with the LOS F, the Northapproaches the DS value of 1.20 with the LOS F, the Southernapproach of the DS value of 1.27 with LOS F, while for the next 10years on the Eastern approach the value of DS is 1.57 with LOS F,Western approach of DS value of 2.25 with LOS F, North approach ofDS value of 2.00 with LOS F, South DS value of 2.12 with LOS F.

Anduonuhu Village is one of the areas in Kendari City that has been affected by flooding in the last 10 years. Data of fload eventsoccurred in 2013 and 2017. Based on the Data of the Kendari CityEnfironmental Status Report in 2010, the distribution of potentialareans prone to flooding in the city of Kendari, Anduonuhu subdistrictwasranked2 (two)withanareaof359.817 ha. The purpose of this sudy is to analyze extreme rainfall over the past10 years, to analyze the factors that cause flooding and the priorityof handling the anduonuhu river. In analyzing, the autors collectdata 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 10years at the study site occurred in 2013 amounted to 191.6 mm.factors causing flooding at the study site were caused by extremerainfall inundating the Anduonuhu watershed and land use change.The priority handling is done by modeling scenarios withnormalization and river embankments.
