Abstract

Abstrak: Analisis Dan Evaluasi Kinerja Bundaran Saronde Kota Gorontalo. Dengan semakin banyaknya pembangunan yang terjadi di Kota Gorontalo, maka perlu adanya tinjauan ulang atau evaluasi terhadap prasarana transportasi sebagai penunjang mobilisasi masyarakat Gorontalo. Evaluasi tersebut dilakukan di bundaran Saronde yang merupakan penghubung Pusat Kota Gorontalo, area kampus Universitas Negeri Gorontalo, pusat perbelanjaan Gorontalo Mall, lapangan Taruna Remaja Gorontalo, serta Rumah Dinas Gubernur Gorontalo. Padahal keberadaan dan peran bundaran Saronde Kota Gorontalo sangat penting bagi dinamisasi lalu lintas masyarakat sekitar yang menggunakan akses bundaran tersebut. Tujuan utama dari penelitian ini yaitu adalah menganalisis hal apa saja yang mempengaruhi kemacetan lalu lintas di Bundaran Saronde kota Gorontalo. Metode pengujian menggunakan penelitian kualitatif dimana pengumpulan datanya dilakukan dengan cara survei volume kendaraan, survei kecepatan kendaraan, serta survei geometri jalan yang kemudian dianalisa dengan menggunakan metode perhitungan dari Manual Kapasitas Jalan Indonesia (MKJI, 1997). Berdasarkan hasil penelitian yang telah dilakukan dapat disimpulkan bahwa kondisi arus lalu lintas atau kinerja yang terjadi pada Bundaran Saronde Kota Gorontalo pada kondisi existing atau tahun 2020 ini sudah melebihi kapasitas yang ada yaitu nilai derajat kejenuhan = 0.974 dan tundaan bundaran rata-rata = 18.06 det/smp. Kondisi existing geometri Bundaran Saronde Kota Gorontalo tidak sesuai dengan peraturan Manual Kapasitas Jalan Indonesia 1997, yaitu dengan diameter bundaran 5.50 meter. Abstract: Analysis and Evaluation of the Performance of the Saronde Roundabout in Gorontalo City. With the increasing number of developments taking place in the City of Gorontalo, it is necessary to review or evaluate the transportation infrastructure as a support for the mobilization of the Gorontalo community.

Material technology and implementation techniques obtained from the results of research and experiments are intended to answer the increasingly high demands on the use of concrete and overcome obstacles that often occur in field work. Improving the quality of concrete can be done by providing substitute materials or added materials. One alternative material that can be used as a substitute is coconut shell fragments. This study was conducted to determine the characteristics of the compressive strength of concrete at the age of 28 days using coconut shell fraction as a partial replacement for coarse aggregate at levels of 3%, 5.5%, 7.5%, 9.5% and 11.5%. Data collection was carried out by laboratory tests based on SNI 2012. Data analysis was carried out by calculating the average test results and then compared with SNI-7656 2012. From the results of the study at the level of 3% coconut shell, the compressive strength value of 20.66 MPA was compared with the compressive strength of normal concrete. The plan according to SNI 7656: 2012 which is 20 MPA increased by 3.3%. Therefore, by using coconut shell fragments as a partial substitute for coarse aggregate in the concrete mixture, it can produce a higher compressive strength value of concrete than the planned compressive strength.
