Abstract

Indraigiri Hilir has a very large peatland. Large peatland is constraint in the development of infrastructure of a region. The problems posed ini the field of contruction is the amount of land degradation and low soil carrying capacity. Therefore, an alternative to the soil reinforcement is required by using the cerucuk timber to increase the carrying capacity of the foundation and soil reinforcement. This research was conducted to determine Musculoskletal Disorders (MSDs) in instalation of piles (the cerucuk timber) using Nordic Body Map Questionnaire. NBM happers due to these 28 body parts are ini direct contact with the activities. The primary cause of MSDs is unnatural working attitude and exessive mucle tension began from design of a working system that is designed not ini accordance with the workers’ limitation

Abstract

The cost control is a very important aspect in project management. Poor cost control often results in project construction costs that differ from planned costs. The applying of the Earned Value Concept method for analytical calculations requires the following data: Implementation time along with the S curve; Volume data of each work item; Percentage of work weighted; Standard daily reports, weekly reports, and monthly project reports; Actual project financial data and SPI. The stage of data analysis for each job are: determining of BCWS (Budgete Cost Of Work Schedule); BCWP (Budgeted Cost of Work Performed; ACWP (Actual Cost of Work performed) Analysis of variance and performance index from the Earned Value Concept method. It consists of: Cost Variance (CV) and Schedule Variance (SV), Cost Performance Index (CPI) and Schedule Performance Index (SPI). The results of the analysis of the applied of the Earned Value Concept method of PT. Riau Maju Cemerlang obtained a gross cost gain of around Rp. 173,591,516.52 or 5.00% of the total construction price without VAT value. The initial planning time for project work began on 26 July and the initial planning time ended on 17 December (145 HK) turned out to be 27 December (155 HK). The applied of the Result Value Concept method to the project can find out the remaining value of the project costs for the remaining work and how much the total cost has been used for the project.

Abstract

AbstractConcrete is a composite material (mixture) consisting of cement, coarse aggregates, fine aggregates and water. The concrete formation mixture is designed in such a way as to produce fresh concrete that is easy to work with and meets the plan's compressive strength after hardening.The cement used is PCC type cement, although the composition of cement in concrete is only about 10%, but the role of cement is very important in concrete. Aggregates are mineral granules originating from nature or artificial which have a function as a mixture of fillers in concrete. The aggregate of the concrete mixture filler is divided into fine aggregates used from Javanese Inhu and coarse aggregates from Tanjung Balai Karimun. The fine aggregate is usually in the form of sand that passes through a filter with a diameter of 4.75 mm or 5 mm, while coarse aggregates do not pass through the filter. The water used is well water from Kateman District, Keritang District and Tembilahan District, Indragiri Hilir Regency, Riau Province.The compressive strength of concrete is the amount of load per unit area which causes the concrete specimen to break and there is no more carrying capacity. The average compressive strength of 28 days of cube specimens with well water in Kateman District = 491 kg / cm2, Keritang District = 469 kg / cm2 and Tembilahan District City = 475 kg / cm2. AbstrakBeton merupakan bahan komposit (campuran) yang terdiri dari semen, agregat kasar, agregat halus dan air. Campuran bahan-bahan pembentukan beton dirancang sedemikian rupa, sehingga menghasilkan beton segar yang mudah dikerjakan dan memenuhi kekuatan tekan rencana setelah mengeras.Semen yang digunakan adalah semen tipe PCC, walaupun komposisi semen dalam beton hanya sekitar 10%, namun peran semen sangat penting dalam beton. Agregat adalah butiran mineral yang berasal dari alam atau buatan yang memiliki fungsi sebagai bahan pengisi campuran pada beton. Agregat pengisi campuran beton terbagi atas agregat halus yang digunakan berasal dari Japura Inhu dan agregat kasar berasal dari Tanjung Balai Karimun. Agregat halus biasanya berupa pasir yang lolos saringan dengan diameter 4,75 mm atau 5 mm, sedangkan agregat kasar tidak lolos saringan tersebut. Air yang digunakan yakni air sumur berasal dari Kecamatan Kateman, Kecamatan Keritang dan Kecamatan Tembilahan Kota Kabupaten Indragiri Hilir Provinsi Riau.Kuat tekan beton adalah besarnya beban per satuan luas yang menyebabkan benda uji beton pecah dan tidak ada lagi daya dukungnya. Hasil kuat tekan rata-rata umur 28 hari benda uji kubus dengan air sumur Kecamatan Kateman = 491 kg/ cm2, Kecamatan Keritang = 469 kg/cm2dan Kecamatan Tembilahan Kota = 475 kg/cm2.

Abstract

The waste problem continues to be a complex issue. On the one hand, the use of plastic still cannot be abandoned by humans, but on the other hand the waste produced is very difficult to decompose. In Indonesia, in 2015 the amount of waste reached 64 million tons / year. Palm fiber is one of the materials that can be used as composite fiber. In this study, a research will be conducted on the manufacture of paving blocks made from HDPE plastic combined with variations of 0%, 1%, 2% and 3% palm fiber. Plastic waste is melted and put into a mold and then combined with palm fiber. From the test results, the highest compressive strength (2% fiber variation) was 45.91 kg/cm2 and the average compressive strength was 45.28 kg/cm2. This compressive strength is under the minimum compressive strength standard of SNI Permasalahan sampah masih terus menjadi isu kompleks. Di satu sisi, penggunaan plastik masih belum bisa ditinggalkan manusia, namun di sisi lain sampah yang dihasilkan sangat sulit terurai. Di indonesia, pada tahun 2015 tercatat banyaknya sampah mencapai 64 juta ton/tahun. Ijuk merupakan salah satu material yang dapat digunakan sebagai serat komposit. Pda penelitian ini akan dilakukan penelitian mengenai pembuatan paving block berbahan dasar plastik HDPE yang dikombinasikan dengan variasi serat ijuk 0%, 1%, 2 % dan 3%. Limbah plastik dilelehkan dan dimasukkan ke dalam cetakan lalu dipadukan dengan serat ijuk. Dari hasil pengujian, didapatkan kuat tekan tertinggi (variasi serat 2%) sebesar 45,91 kg/cm2 dan kuat tekan rata-ratanya sebesar 45,28 kg/cm2. Kuat tekan ini berada di bawah standar kuat tekan minimal dari SNI.
