Abstract

At mining industry usually use blasting method to breaking hard and compact rock. Blasting operation using two types of stemming material such drill cutting and crushed rock or composite of both. Stemming is column at the top of blast hole that filled by its. Length of stemming column and types of stemming materials can influence the result of blasting fragmentation. Longer stemming will produce a boulder while shorter stemming will produce fly rock and the fragment size is too small. Stemming material too soft can cause the blast energy distribution not separated well so the blasting operation achievement is not optimum.This research observed and evaluated the blasting fragment size, boulder, and blasting recovery that occur from mining blasting activity used two types stemming material such drill cutting and crushed stone.The result indicated use of drill cutting material is not strong enough to withstand the blast energy towards to the top of blasting hole then produce fly rock and 26.6 % boulder. Crushed stone material gives the best result for 10.09% boulder and 93% blasting recovery but need more expense for it. The improvement using double deck method with combine stemming material is better and gives the optimum blasting with 8.8% boulder and 91% blasting recovery.

Abstract

Strengthenning and Retrofitting methods already had applicated in buildings. Beam is One of structure elements can be strengthenned  in  order to maintain efficient serviceability structure that can be caused change of function from structures likes overloading or lack of quality control at construction so it can fulfill the code of structures to day and future.  This research had to know about effectiveness strengthening methods of reinforced concrete beams using longitudinal compression and tension reinforcement with jacketing mortar as flexural strengthening  and had to know effectiviness of theoritical methods for interpreting result . In this research specimen models consist of  four specimens: one was control beam (BK), one was monolith beam (BM) and one was strengthened beam (BP)without bonding agent and BP2 was strengthenned beam with bonding agent . All beams were tested under 2-point loading midspan as flexural load and also instrumented for the measurement of mid-span deflection and crack pattern. Test result were  compared to analytical method and program computer based layer method (software Response-2000). The result shows performanced of Response-2000 as layer method an theoritical methods provided equal performances if compared with experimenta method. It can be shown that the percentags  of  Ultimate Load between Response 2000 with experimental method was 107 % -109% for BK, 110,42-111,40% for BM , 83,77% - 83,81% forBP1 dan 87,66-87,70 for BP2. Failure patterns of the control beam (BK) and monolithical beam (BM) were flexural while the strengthened beams had debonding. At this researched, an analythical method (Response-2000)also presented equal performance at failure patterns. It can be shown two specimens (BK and BM) were flexural failured an others (BP1 and BP2) were debonding failured too.

Abstract

Banjarmasin dan daerah sekitarnya, kondisi wilayah yang keadaan tanah dengan daya dukung rendah, karena daerah terendam dan tanahnya sangat lunak. Kerusakan jalan yang lebih cepat pada kondisi tanah dasar lunak. Pada umumnya urugan menggunakan urugan biasa. Tapi umumnya dengan urugan di atas tanah lunak ini, jalan akan rusak dengan cepat, biaya maintenance tinggi. Diperlukan waktu antara 5-10 tahun baru badan jalan mulai stabil.  Sudah ada contoh di tempat lain, urugan dengan material pilihan diperkuat dengan geotextile ternyata membuat badan jalan lebih stabil dan tahan lama, maintenance relatif rendah, tapi dengan menggunakan material pilihan dari lokasi lain, akan memerlukan biaya (transportasi, waktu), menimbulkan masalah lingkungan, dan juga kesulitan mendapatkan material.

Abstract

Roughness channel factor, widely known as Manning’s value, is an important parameter in open channel flow analysis. For channels with different material composition or composite channels, determination of Manning’s values becomes difficult enough to be done. This study aimed to investigate how flow depth variations affect  Manning’s values of composite channel. The research was done by examining and calibrating the Manning’s values for glass sided flume with gravels on the bed of channel, namely gravel-glass channel . The observation of water surface profiles and flow velocities used  five variation of flow depths in the upstream with a weir in the downstream of channel (0.4 m , 0.35 m , 0.3 m , 0.25 m , 0.2 m) and also without a weir. The channel had a rectangular cross section with a width of 0.3 m and  bed slope 0.0001. The calculation of water surface profiles for composite channel used direct step method. The results pointed out that the Manning’s value of  gravel-glass channel was grealyt influenced by water surface profiles along the channel. For Mild 1 (M1) profile, Manning’s value became smaller as decreasing of flow depths, while for M2 profile, Manning’s value became greater as decreasing of flow depths. Key words: Manning’s coefficient equivalent, composite channel, direct step method, water surface profie simulation

Abstract

This simulation show 2 major problems, first about wind force in Indonesia loading code, 1970 which is older and no revision. Second, about signboard design for wind force in Indonesia loading code and British loading code, which is British code using envirotment, location and  elevation for wind force. Model Simulation are one leg signboard (baliho type) and two leg signboard. This simulation using finite element software. Result show a lower wind force than British code, which might to consider a revision for Indonesia wind force code. Another result show that deflection in one leg signboard is large if there always a maximum than code . This is a reason why two leg is now use in Banjarmasin.

Abstract

Often the cut side of the plate pieces on the lever scissors is not good (distortion occurs). This is due to the incompatibility of cutting variables, such as clearance and cutting angle of both scissors knife. The extent to which the effect of the clearance and the cutting edge of the scissor knife on the cutting of the steel plate is to be studied to obtain the appropriate cutting parameter as reference in the slashing work of the plate with the lever scissors.This research is aimed to know the proper clearance and cutting angle for various variations of steel plate thickness. The thickness of the steel plate as a specimen of the test specimens was of a size 1.61 mm, 2.63 mm, 3.85 mm, 4.95 mm and 5.39 mm, respectively. While the variation of cutting angle of scissor knife include: 75o, 77,5o, 80o, 82,5o and 85o.The test results showed that cutting of 1.61mm thick steel plate with 0.5 mm clearance and 77,5o cutting angle resulted in good cuts with 45% incision depth. On steel plates with thickness of 2.63mm and 3.85mm, the best cut results at 1mm clearance and cutting angle of scissors knife 77,5o, where the depth of incision successively reached 35% and 25%. For thick plates 4.95 mm and 5.39 mm, the best results of the incision depth were respectively 20% and 18% on clearance 2 mm and cutting angle 82,5o.
