Abstract

Nowadays, delays in project often occur and cause various losses both for service providers and users. For the contractors, delays create the project cost overruns due to project overtime and can decrease contractor credibility in the future. This study aims to analyze a project delay by minimizing the work delays earlier. The analysis of a hotel building planning regarding the cost and time delays is done qualitatively by distributing questionnaires to the contractors and processing the responses using the SPSS software. The results of the S curve analysis and 30 factors that caused the project delay were identified and indicated that there was a delay value of 1.26% with five variables that most contributed to the delay in the construction project at PT. Wijaya Kusuma Contractors, i.e. reworking due to construction errors, low coordination between contractors and stakeholders, late material delivery, and equipment shortages.

Abstract

Aerated lightweight concrete or called Autoclaved Aerated Concrete, is also one of the alternative substitution material of solid red brick. Aerated lightweight concrete now has been widely marketed in several building materials stores and it is used in the project in Indonesia. Aerated lightweight concrete is a concrete which has a lighter specific gravity than a concrete which is generally made by adding the expandable material to create any cavities within, as thus the weight becomes lighter. Aerated lightweight concrete has two types: the wall panel type and the block type, with varied sizes depending on the manufacturer and type of utility. Aerated lightweight concrete weights around 600 - 1600kg/m3 and it can withstand loads up to ± 1200 psi or ± 84.372kg/cm2. Therefore, it is good for construction, especially for wall-constructing since it reduces the burden which is distributed to the foundation. The installation is faster and precise; hence it will save the time and reduce the cost of repairing

Abstract

Tanaman Eceng Gondok yang tumbuh sangat cepat berdampak negatif bagi fungsisungai, rawa dan danau dimana akar tanaman yang menggantung ini menyerap oksigenyang berada disekitarnya. Aliran air sungai jadi terhambat karena penuh oleh tanamanEceng Gondok, oleh karena itu perlu adanya pemanfaatan Eceng Gondok yang positifseperti sebagai bahan tambah campuran beton.Pengujian laboratorium dilaksanakan dengan menambahkan serat batang EcengGondok pada beton. Penambahan serat sebesar 0,25 %, 0,50 % dan 0,75 % subtitusiterhadap agregat halus. Pengujian yang dilakukan yaitu uji kuat tekan dan uji kuat tarikbeton dengan mutu K-225.Hasil penelitian menunjukan penurunan kuat tekan beton sebesar 7,54 % terhadapbeton normal pada komposisi serat Eceng Gondok 0,25 %. Begitu juga dengan nilai kuattarik beton terjadi penurunan sebesar 7,57 % terhadap beton normal pada komposisi seratEceng Gondok 0,25 %. Seiring dengan pertambahan kadar serat Eceng Gondok, nilai kuattarik dan tekan semakin menurun.

Abstract

Material construction resources are very limited, but the demand for these materials tends to increase. Therefore, it is necessary to search for alternative materials such as utilizing used goods (garbage) as construction materials. An alternative material used in this study was iron shavings waste as an additional material in the concrete brick mixture to replace sand. Therefore, it can minimize the use of sand and reduce iron shavings. The study was conducted by changing the standard size of the brick according to SNI to a size of 10 x 10 x 10 cm. The results showed that the addition of iron shavings in the concrete mixture was able to increase compressive strength value. The percentage increases in compressive strength of normal concrete blocks were: 14.87%, 24.79%, 45.45%, and 71.90%. The compressive strength of ordinary concrete brick of age 7 days is 41,374 KN, and after iron shaving addition the strength improve by 47,529 KN, 51,632 KN, 60,18 KN and 71,123 KN with the percentage of iron shaving of 2.5%, 5% , 7.5% and 10% respectively. These improve value was also categorized as quality I, II and III according to SNI 03-0349-1989 requirement.

Abstract

One reinforced beam element that experiences a shear failure is a high beam; a beam that follows a requirement based on SNI-2847-2013 standard that have the proportion of sliding span (l) and the effective height (d) not more than three. The type of collapse in high beams generally is shear failure in which the crack appears from the area around the placement, propagates and reaching the maximum value at the point of loading. Observation of crack patterns and ultimate loads can be done by several methods based on both non-linearity and linearity of materials. Two specimens consisted of one high beam conventional reinforced concrete and one high beam concrete fiber with a dimension of 170 mm x 420 mm x 850 mm were prepared. Fiber from machine turning waste was used as coarse aggregate substitution with 100% composition in fiber concrete. Both specimens were tested in the laboratory and observed for crack patterns analysis and ultimate load achievement. The experimental test results were then compared with the numerical test results for the non-linearity properties of the material and the Strut and Tie method for the linearity properties of the material. The ultimate high beam of conventional reinforced concrete when experiencing shear failure in the experimental method, numeric method, and strut and tie method were 310 KN, 290 KN, and 236.917 KN respectively, whereas in the high beam fiber concrete, the ultimate load in the experimental method, numeric method, and in the strut and tie method were 280 KN, 260 KN, and 263,917 KN respectively. The biggest ratio of test results were obtained from the comparison between the numerical and the experimental methods in conventional concrete which was equal to 0.94. This showed the similarity of non-linearity properties of the material to produce adjacent test results.

Abstract

Bambu mempunyai sifat mekanik yang baik karena hampir menyerupai sifat mekanik baja. Bambu dapat digunakan pada konstruksi bangunan sipil sebagai material alternatif pengganti baja seperti perkerasan kaku jalan raya (rigid pavement). Pada rigid pavement baja digunakan sebagai tulangan yang berfungsi untuk menahan retak susut akibat suhu dan menambah kapasitas beban jalan. Penelitian ini menggunakan bambu pada rigid pavement. Spesimen yang dibuat adalah meshing tulangan bambu dan baja dengan panjang 5 m dan lebar 3,5 m, diameter 12 mm dan tulangan dipasang pada jarak setiap 100 mm. Meshing tersebut masingmasing dipasang pada tiap segmen jalan yang berukuran panjangxlebarx tinggi yaitu 3,5m x 5m x 0,3m pada kedalaman 20 cm dari permukaan jalan. Uji dilakukan dengan menggunakan beban kendaraan yang divariasikan mulai dari 1000 Kg sampai dengan 14000 Kg dan diamati responnya seperti defleksi, regangan, tegangan. Defleksi terbesar pada perkerasan rigid pavement tulangan bambu adalah 0,6 mm pada beban 9323 Kg. Tegangan maksimum yang dihasilkan pada tulangan baja memanjang dan melintang adalah 1062,6 Kg/cm2 dan 686,7Kg/cm2 dengan nilai E baja 2100000Kg/cm2 , sedangkan pada bambu tegangan terbesar yang dihasilkan adalah 118,62Kg/ cm2 dan 86,87Kg/ cm2 dengan nilai E bambu 313810Kg/cm2 pada kondisi ini tegangan yang terjadi masih dalam batas elastis. Hasil penelitian menunjukkan bambu layak dipakai sebagai tulangan pada rigid pavement

Abstract

This activity aims to optimize the packaging of Sukamukti Village MSME products using a press machine. The method used involves the application of press technology in the packaging process to ensure the compactness and durability of the product packaging. The press tool used is able to produce neater and more uniform packaging, thereby reducing the risk of product damage and improving packaging aesthetics. The results of applying the press show a significant increase in the quality of product packaging, both in terms of durability and visual appearance. This improvement in packaging quality has a positive impact on consumer experience, because they tend to choose products that are packaged well. Thus, the use of press equipment for packaging MSME products in Sukamukti Village has proven to be effective in improving product image and competitiveness in the market. This research provides recommendations for MSMEs in other villages to consider similar technology as part of their packaging strategy.
