Abstract

Lightweight bricks could be used as the substitute of conventional bricks for building wall materials. Lightweight brick has a weights beetween 600 to 1800 kg/m3. In this research, lightweight bricks were made by trial and errors made by adding combination of 0.3%, 0.6%, 0.9%, 1.2% and 1.5% of foam agent by cellular lighweight concrete (CLC) method. The optimum compresive strength was gain at 0.9% of foam agent. CLC lightweight brick is the type of bricks which is constructed by adding air bubbles/foam agent to mortar mixture. It is necessary for the air bubbles to retain their shapes during the curing process of the mortar without triggering chemical reaction. An airlock was in a mixture of mortar structure of the cells that produce material, which contains the cavity the air with the size of the between 0,1 to 1,0 mm thick and spread uneven so that makes the nature of concrete better to prevent heat and more voice The curing process was performed by storing the samples indoor, in which the room temperatur varies over time. The sample size was 60x20x7.5 cm, made to investigate the impact of foaming agent to the compressive strength of the lightweight bricks. The experiment method was carried out based on SNI 03-6825-2002. As a result, the compressive strength was 0.49 MPa at 7 days, 0.23 MPa at 14 days, and 0.67 MPa at 28 days. In addition, according to the furnace tests, the lightweight bricks resist for heat temperature of 500ºC. Also, The acoustic test results also shows that the lightweight bricks absorb sound by 3%.Keywords : brick light, foam agent, strong press, acoustic monitoring, furnace

Abstract

Project implementation have always refers to the construction assumption and forecast while time plans and schedule were made, Therefore, the contruction problem will arise if there is a discrepancy between plan and assumptions comparing to the actual project. Delays of project implementation is generally always lead to adverse consequences both for the owner and contractor. The project the (SKPD) Unit City Government of Pekanbaru in Riau is having a delay of 75 days. The Best construction time acceleration is 45 days. Construction acceleration can be conducted by 3 alternatives solutions such as: overtime alternative, equipment and workers addition alternative, and shift system alternative. The analysis started from the critical path. Network project the analysis, was obtained from the cost due to delay stands at Rp. 4.761.786.975,00. Cost of construction acceleration caused by overtime alternative is Rp. 2.152.360.596,00 with a total 11.136 hours of extra work for workers, cost of construction acceleration by the workers and equipments additionionally for alternative result Rp. 2.434.965.492,00 with a total 14 new workers, with additional of 2 new equipment units. Cost of construction acceleration from shift alternative is Rp. 2.434.965.492,00 with a total of 14 new workers, a total 2 of equipment units. In conclusion, the most effective construction acceleration method is overtime alternative, obtained the minimum financial loss and recommended to use for the construction acceleration.Keywords : construction delay, construction cost, duration shortening, overtime, work equipment and workers additional.

Dampak nyata perilaku seks pra nikah remaja adalah kehamilan, aborsi dan putus sekolah.  Remaja banyak menghabiskan waktu dengan teman sebaya serta pengaruh teman sebaya dapat membawa akibat positif maupun negatif.  Peer konselor adalah program pemberdayaan teman sebaya untuk dapat memberikan informasi dan pengetahuan kesehatan serta konseling bagi remaja. Tujuan penelitian ini adalah mengetahui efektifitas peer konselor berbasis KERIS-net terhadap perilaku seksual remaja. Desain penelitian ini quasi-experimental design dengan jumlah sampel 180 remaja yang terdiri dari 90 remaja kelompok eksperimen dan 90 kelompok kontrol. Hasil penelitian menunjukkan ada perbedaan yang signifikan antara perilaku remaja sebelum dan setelah penerapan peer konselor berbasis Keris-net (ρ<0,05).
