Abstract

One cause of the poor quality of some concrete blocks in the city of Palu is the lack of cement used in the concrete block. This is caused by the high price of cement so that income of concrete blocks maker decreases. To find a way out of these problems, a lot of waste material that can be used in the manufacture of concrete block, one of which is coal fly ash. The purpose of this activity is to introduce the use of coal fly ash in the manufacture of concrete block to business partners of  the concrete block makers in Palu city. The purpose of this activity is to make concrete block business group partners can increase their income without compromising quality concrete block produced.Activity counseling / coaching and mentoring manufacturing concrete block using coal fly ash has been done to the concrete block makers. To facilitate the implementation of the concrete block-making, each made the graduated graduated barrel of sand, cement and coal fly ash graduated. To facilitate the implementation of the concrete block-making, made barrel graduated ie graduated sand, cement and coal fly ash graduated. The composition of the mixture is introduced to the partners is 0.75 sacks of cement: 0.25 sacks of coal fly ash and ± 300 kg of sand or 1 cement barrel dose: 1  coal fly ash barrel dose and 2  sand barrels doses. The results of this activity is to get that quality of concrete blocks produced by using coal fly ash strongly increased compressive strength but does not increase the quality of concrete blocks (Remain quality II). This activity was also found that any use of the three sacks of cement will result in an additional gain of ± 130 concrete blocks. This indicates that the use of coal fly ash in the manufacture of concrete blocks to provide added value to the concrete blocks makers.

Abstract

Salah satu pusat kegiatan yang perlu analisis dampak lalu lintas adalah gedung pertemuan. Namun, standar tarikan perjalanan belum ada dan akan memberi dampak pada ruas jalan di sekitarnya. Oleh karena itu penelitian ini memiliki tujuan untuk mengetahui besaran tarikan perjalanan serta dampak lalu lintas yang terukur akibat adanya gedung pertemuan pada ruas jalan dan simpang tak bersinyal di Kota Palu. Penelitian dilakukan pada gedung Mary Glow (MG) sebagai salah satu gedung pertemuan terbesar di Kota Palu. Perhitungan tarikan perjalanan menggunakan analogi dari Gedung MG sebelumnya. Survei tarikan perjalanan dilakukan dengan menghitung traffic movement per 15 menit di pintu masuk Gedung MG dan simpang tak bersinyal selama event dan tidak ada event kemudian dibandingkan. Kinerja ruas jalan dan simpang tak bersinyal berdasarkan MKJI 1997. Hasil penelitian menunjukkan bahwa besaran tarikan perjalanan dapat ditentukan berdasarkan kendaraan yang keluar-masuk area gedung pertemuan dengan menggunakan analogi terhadap kapasitas gedung. Kasus pembangunan Gedung MG untuk lima tahun mendatang menunjukkan bahwa pengoperasian gedung pertemuan dapat menurunkan tingkat pelayanan secara signifikan pada simpang tidak bersinyal yaitu dari tingkat pelayanan C menjadi D, sedangkan pada ruas jalan tidak signifikan yaitu tingkat pelayanan tetap B.

Abstract : Basuki Rahmat Street is a National Road with a primary-arterial-function based on the Regional Master Plan of Palu City 2010-2030. The area is focused as a trade and service area which attracts visitors to have economic and social activities. Therefore, each section of the road has other traffic performance. The research was conducted in three road segments: Grand Hero Supermarket, Samsung store, and BCA Bank, and Star Kitchen Electronic Center based on traffic generation of business activity. The study aims to understand Basuki Rahmat street's performance and its activities in each segment. A survey was conducted periodically (early, middle, and end of the month) by taking a workday and a holiday for each period, from 09.00-22.00 WITA. The evaluation method was based on the Indonesian Highway Capacity Manual (IHCM) 1997 urban area on peak hour. The result showed that the Road Segmentation Method (RMS) of Basuki Rahmat street has 0.37 degrees of Saturation (DS) and was included in a B level of service. The differences between DS-RMS and DS on each segment were 0.04. The road segmentation method should be considered to assess the traffic performance of the road link.
