TINJAUAN PERENCANAAN MANAJEMEN KONSTRUKSI PADA PEMBANGUNAN GEDUNG REHABILITASI NAPZA KOTA PONTIANAK

Andini Febriski Fajar — 2023-12-29

When carrying out a construction project activity, a construction management system is needed. Construction
Management includes management of project cost control (RAB), time (Schedule), human resources (HR),
project occupational health safety management (SMK3L) and risk classification and control. Project
implementation control must be carried out from the beginning of the work until the project work is completed
so that construction management must be by the implementation. The results of the review of construction
management planning for the construction of the NAPZA building were dominant in the implementation phase,
especially in time control where the project construction process which was originally planned for 148 days
or approximately 22 weeks became 24 weeks. This resulted in the problem of processing time where the target
was not achieved and resulted in delayed project work. Project implementation control must be carried out
from the start of work until the project is declared complete so that during the project development process
unwanted problems can be avoided. The construction management that will be applied to the NAPZA building
can make the project run well and according to the desired schedule.

Manajemen dan Rekayasa Lalu Lintas Terhadap Dua Simpang Bersinyal Yang Berdekatan (Studi Kasus Simpang Empat Jalan KH.A Dahlan – Jalan Karimata – Jalan Johar dan Simpang Tiga Jalan KH.A Dahlan – Jalan Alianyang – Jalan KHW. Hasyim) Pontianak

The number of intersections with adjacent intersections in Pontianak City raises its own problems, one of which is the signalized intersection on Jalan KH. Ahmad Dahlan Pontianak. The short - term strategy to overcome these problems is traffic management and engineering to improve traffic flow based on field condition evaluation . Data collection was carried out by means of direct surveys at both intersections. The data obtained is used to obtain the existing conditions which will be a reference in planning a new cycle time by taking into account the coordination theory. Meanwhile, in calculating to get the best performance at each intersection, it is done using the MKJI approach. The best performance at each intersection is then coordinated using the green time between intersections. The results of the analysis of the performance of the existing conditions show that the degree of saturation is DS = 0.86 for signalized intersection 4 and DS = 0.68 for signalized intersection 3 which are not too different from what MKJI requires, DS = 0.75 , but it is not comfortable and safe to go through. From the queue length (QL) at the four intersection of 288 meters > the distance between the intersections which is 200 meters apart, and also from the delay time (DQ) of 66.03 seconds > from the green cycle time of 25 seconds, After knowing the performance of the existing intersection, then create a new cycle time planning for both intersections. The new cycle time with the best performance will be used to coordinate the two intersections. Selection of the best cycle time by comparing the values of the degree of saturation (DS), the length of the queue (QL), and the delay (Delay) from several alternatives that were carried out. From the results of the study, a new cycle time of 95 seconds was obtained. The offset time used is 36 seconds, and the bandwidth from East to West and from West to East is 16 seconds. With the new cycle time the performance values of the two intersections get better because the average delay and queue length decrease, for intersection 4 (DS = 0.76; QL = 136 m; DQ = 67 seconds) and intersection 3 (DS = 0, 67; QL = 94.5 m ; DQ = 65.37 seconds),

PENGARUH PENGGUNAAN BASALT FIBER PADA SIFAT MEKANIS BETON GEOPOLIMER DENGAN KOH SEBAGAI ALKALI AKTIVATOR

ayub Konstatinus Moambura — 2023-12-29

Concrete is the most important material in building construction, including bridges, piers and buildings.
Concrete is the main raw material in construction nowadays, where wooden construction is starting to be
abandoned
This research aims to evaluate the effect of using basalt fiber on the mechanical properties of geopolymer
concrete using KOH as an alkali activator. Geopolymer concrete is an environmentally friendly alternative
construction material, which replaces the use of portland cement with a geopolymeric binder. The addition of
basalt fiber is expected to improve the mechanical properties of geopolymer concrete, namely its compressive
strength.
Stages of this research method involve making geopolymer concrete samples with varying compositions,
including varying the concentration of KOH as the alkali activator and the percentage of basalt fiber added.
These samples will be tested to evaluate their mechanical properties, namely compressive strength, and other
physical properties. It is hoped that this research will result in a better understanding of the influence of the
use of basalt fiber on the mechanical properties of geopolymer concrete. It is hoped that the results of this
research can become a basis for the construction industry to improve the performance of geopolymer concrete
by using basalt fiber as reinforcement. Apart from that, this research will also provide new insights into the use
of KOH as an alkali activator in geopolymer concrete. Currently, TKT in research has a value of 1, namely
formulating a geopolymer concrete mix design concept and the final target of the results of this research is to
demonstrate scientific feasibility through analytical and laboratory studies, proof of concept and geopolymer
concrete products that meet construction material standards.
