Dalam perencanaan pembangunan suatu proyek umumnya tidak dipertimbangkan alternatif yang dapat mengurangi biaya-biaya yang tidak diperlukan. Pekerjaan pembesian secara manual pada pekerjaan balok dan kolom serta pekerjaan pelat konvensional pada Proyek Pembangunan Gedung Kantor Badan Pusat Statistik (BPS) Provinsi Sulawesi Tenggara akan dicoba alternatif lain dengan melakukan analisa rekayasa nilai. Dengan analisa tersebut diharapkan dapat menguragi biaya-biaya yang tidak diperlukan sehingga dapat mengoptimalkan biaya dan waktu tanpa mengurangi mutu yang diinginkan. Analisa rekayasa nilai ini menggunakan tahap-tahap rencana kerja rekayasa nilai yaitu : tahap informasi, tahap spekulasi, tahap analisa dan tahap penyajian. Untuk menilai alternatif-alternatif pekerjaan dengan analisa rekayasa nilai ini, digunakan kriteria-kriteria penilaian beserta bobot penilaiannya. Kriteria-kriteria yang digunakan terdiri dari biaya, waktu, hasil akhir dan pelaksanaan. Alternatif usulan yang memungkinkan untuk diterapkan dalam proyek tersebut diatas adalah pekerjaan pembesian manual dengan mesin dan pekerjaan pelat halfslab tulangan polos dan pelat halfslab tulangan wiremesh. Berdasarkan analisa yang dilakukan, diperoleh alternatif yang dapat memenuhi fungsi dengan penghematan biaya yang paling besar dibandingkan dengan alternatif-alternatif lainnya, yaitu pelaksanaan pekerjaan pembesian manual dengan mesin dan pelaksanaan pekerjaan pelat halfslab tulangan wiremesh. Dengan penghematan potensial sebesar Rp. 479.328.386 atau serta untuk waktu pelaksanaan dapat dihemat selama 11 hari.

Knowing the characteristics of wastewater and its interaction with the channel is crucial to finding a suitable model and maintenance method to solve the closed channel problem. The purpose of this study is to find the relationship and how much it influences the characteristics of wastewater in closed channels and analyze the limit deposit velocity (LDV) of wastewater so that there is no deposition. The parameters used to analyze wastewater characteristics are density, oil and fat, specific gravity, total suspended solids, total dissolved solids, and kinematic viscosity. The parameters used to analyze the flow characteristics in closed channels are velocity, discharge, Reynolds number, friction coefficient, energy loss, and hydraulic gradient. The method used is experimental research by simulating a closed-channel model prototype. The closed channel model is made from an acrylic pipe with a length of 6 m and a pipe diameter of 0.064 m. Simulations on each wastewater sample and the discharge variations used were 0.005, 0.004, 0.003, and 0.0015 m3/s. Velocity measurements at a 0.5 pipe water level height and distances of 0, 2, 4, and 6 m. The results showed that the nature and composition of the wastewater the flow velocity. The large value of wastewater parameters shows that the flow velocity is small. The wastewater content is considered a load that must be transported to the end of the closed channel. When the discharge increases, the velocity will increase, Reynolds number will increase, and the energy loss will be large, while the friction coefficient is inversely proportional to Reynolds number. The velocities of clean water samples are 2.90 - 1.07 m/s, tofu - making is 2.83 - 1.07 m/s, household is 2.74 - 0.85 m/s, laundry is 2.84 - 1.03 m/s, and the workshop is 2.54 - 0.66 m/s. The limit deposit velocity (LDV) for household wastewater is 1.49 m/s to prevent deposition in closed channels. Doi: 10.28991/CEJ-2023-09-01-03 Full Text: PDF

One of the advances in entertainment facilities and facilitation in the city of Kendari is progress in the internet (virtual world) and in the field of games. This can be seen with the emergence of various entertainment facilities that are engaged in internet cafes (internet cafes) and games. Game Center in Kendari with the Morphosis Architecture Approach is the process of making a container or place that is centered to provide entertainment about the development of games in Kendari City with the process of forming an innovative, iconic building and friendly to the urban environment. The basic concept of Game Center planning and design in Kendari City through interior and exterior structuring with an emphasis on innovative studies iconic buildings and friendly to the urban environment as a goal of the Game Center with the concept of Morphosis Architecture. Game Center Planning in Kendari with the Morphosis Architecture approach must be used in accordance with the functions outlined in the design reference so that it can have a positive impact both for the building manager, the government, the drafting of further references and the wider community.
