PENGARUH PERGERAKAN ANGKUTAN UMUM TERHADAP KEPADATAN ARUS LALU-LINTAS (STUDI KASUS: RUAS JALAN ANDI TONRO MAKASSAR)

Abstrak Perbedaan asal - tujuan wisata dan pola penggunaan lahan menghasilkan volume yang berbeda dan waktu gerakan di jalan-jalan. Sepanjang hari pada fluktuasi lalu lintas jalan, seperti menjadi padat pada jam-jam tertentu dan bergoyang di lain waktu. Misalnya di Bagian Jalan Andi Tonro Makassar. Efek pada jumlah angkutan umum di daerah juga merupakan indikator dari peningkatan arus lalu lintas di jalan ini, salah satunya adalah transportasi umum (minibus). Dimana Jalan Tonro Makassar Andi adalah pilihan dari beberapa ini rute trek transportasi kota. Kondisi arus lalu lintas pada jam sibuk (peak hour) di jalan-jalan waktu Andi Tonro studi ini dilakukan, hasil perhitungan dapat dilihat total volume rata-rata jam puncak (peak hour) di Jalan Andi Tonro = 315,031 smp / jam dengan kecepatan (V ) = 21,90 km / jam. MKJI diperoleh berdasarkan kapasitas (C) = 2755 smp / jam, dengan waktu perjalanan (TT) = 0.046 jam, tingkat layanan "D" dengan nilai 0,9, yang berarti arus lalu lintas dari jalan mulai tidak stabil

Potency Of Sugarcane Bagasse Ash Partial Substitution Of Cement In Concrete

the availability of sugarcane bagasse ash produced by Arasoe Sugar Factory, it is not used utilized. That sugarcane bagasse ash has size very fine that it can pollute the air. The sugarcane bagasse ash has silicate content, and it has pozzolan properties. The needs of construction material are something that to think about that. It is an alternative to substitute the using of cement in concrete construction. This study is aimed to find the potential of sugarcane bagasse ash in Arasoe Sugar Factory for partial substitution of cement in concrete. The sample made from the variety of sugarcane bagasse ash 0%, 2.5%, 5%, and 7.5% as partial substitution of cement in concrete. The ratio of water and cement is 0.45. The specimen of concrete is taken care in standard condition at the laboratory and compressive strength test when the sample is in 28, 45, and 62 days old. The compressive strength test refers to ASTM C39/ C39M-01 (Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens). The development of compressive strength of concrete with many variations of sugarcane bagasse ash 0% 2.5%, 5% is increasing along with the age of concrete, however in contrast with 7.5% of sugarcane bagasse ash the decreasing in 60 days old later. Partial substitute of sugarcane bagasse ash in concrete is possible to do in an amount about 5% of sugarcane bagasse as
