Abstract

AbstractBandar Lampung City is the third largest and most populous city on Sumatra Island with a population of 1,033,803 people (BPS, 2018). Due to the large population, traffic jams often occur, one of which is on Jalan Pangeran Antasari. The road is a City Street class which has a length of 5.6 km and a width of 15 m.Methods Data collection is carried out during peak hours, namely in the morning at 07.30 - 09.00 WIB and during busy afternoons at 16.15 - 17.45 WIB on weekdays, namely Tuesday and Friday. The method used is a moving car observer. The data collected is data on density, speed and fuel demand. The calculation results are obtained from type I vehicles, namely vehicles with a capacity of 1469 cc for liters of gasoline which are widely used during trips in the afternoon, namely 0.46 liters of gasoline with the largest average density of 67.28 pcu/km. From type II vehicles, which are vehicles with a capacity of 2000 cc for liters of gasoline which are widely used for travel, namely 0.7 liters with a density of 90.99 pcu/km in the afternoon hours. Of the two types of vehicles in this study, the consumption of liters of gasoline is greater, that is, it occurs in type II vehicles with a capacity of 2000 cc compared to type I vehicles with a capacity of 1496 cc. The greater the density value, the more gasoline is used.Keywords: BBM, Congestion, Jalan Pangeran Antasari.

Abstract

The load from vehicles received by rigid pavement is characterized as dynamic load that move and change quantitively, so the r2eaction accepted by rigid pavement is the combination of compressive and tensile strength. In the reaserch, as the effort to know the effect of flexural and split tensile strength on normal quality concrete with 0%, 0,4%, 0,6% and 0,8%. The samples of flexural tensile strength testimonial use 60 cm x 15cm x 15 cm beam and the sampes of split tensile and compressive strength test use 15 cm x 30 cm cylinder. As the result, the concrete sample with 0,4% of volume fraction has the most significant progress in the flexural tensile strength, split tensile strength and compressive strength. The result of this research also shows that the progress of flexural tensile test sample reach 9,42%, split tensile strength 7,5% and compressive strength 6,12% from concrete sample with 0% of volume fraction and it has decreased test result from 0,6% and 0,8% of volume fraction. The maximum of flexural tensile test, split tensile test, and compressive test are 6,62 MPa, 2,58 MPa, and 30,54 MPa. Key words : Melaleuca bark fiber, flexural tensil strength,split tensil strength, compressive strength, volume fraction, and rigid pavement.

Abstract

Kebisingan adalah salah satu parameter fisik yang sangat berpengaruh pada lingkungan kerja Gedung Laboratorium Terpadu Sentra Inovasi Teknologi merupakan salah satu Gedung yang didalamnya penuh dengan kesibukan. Salah satu factor yang sangat berpengaruh pada kenyamanan kerja adalah kebisingan. Gangguan stress yang dialami oleh para pekerja salah satunya adalah kebisingan didalam Gedung akibat brisiknya gelombang suara dari luar Gedung. Laboratorium LTSIT berada disepanjang jalan protocol kampaus yang diapit oleh tiga fakultas, Fmipa, FKIP dan F Kedokteran. Suasana jalan kampus didepannya sangat ramai kendaraan roda dua dan roda empat. Disebelah kanan Gedung LTSIT terdapat Gedung kemahasiswaan Fmipa. Sasana Gedung kemahasiswaan sangat brisik dan gelombang kebisingannya masuk kedalam ruangan Gedung LTSIT yang berjarak 2 m. Pada penelitian ini kami mencoba meneliti empat ruangan dilantai-1 yang terdiri dari R1-1.0,R1- 1.1,R1-1.2 dan R1-1.3, Penelitian menggunakan metode penyatuan parameter yang sejenis berbasis pada persamaan kenyamanan ruangan (RCE) dan persamaan kenyamanan Gedung (BCE). Dengan kedua metode ini akan diketahui kenyamanan ruangan didalam gedung. Bila kenyamanannya terpenuhi dan berstandar SNI maka suasana didalam gedung berdampak sangat baik bagi pekerja dan sebaliknya. Hasil penelitian menunjukan tingkat kebisingan diruangan lantai -1: RCE.R1-1.0= …. RCE.R1- 1.1=….RCE.R1-1.1= 1…..dan RCE.R1-1.2= 1……sehingga diperoleh BCE = 1 + 1 + 1 +1 Berdasarkan syarat batas ideal untuk pengukuran empat parameter homogen adalah 3.96 < Pt < 4,04, karena nilai BCE = 4…. berada diluar batas ideal. Menunjukan bahwa suasana Gedung LTSIT
