Abstract

Asphalt is a thermoplastic material that will become harder or thicker if the temperature is reduced and will be soft or more liquid if the temperature increases. As developments in asphalt mixtures, several studies have developed the use of plastic waste in an effort to reduce plastic waste that is difficult to recycle. In this research used type of PP plastic (Polypropylene) as alternative of asphalt mixture. the results of the study showed the lowest stability value that is on the normal laston of 1136 kg, but the value still meets the specification of Bina Marga> 800kg. The lowest flow is on the normal laston of 3.62, the value still meets the provisions of Bina Marga > 3. The lowest Marshall Quotient value on the normal 307, is still meets the requirements of Bina Marga > 250. With the addition of PP plastic (Polypropylene) 2% and 4% showed better results than normal asphalt. Judging from the stability, flow and MQ values, they are better than the normal asphalt.

Abstract

HRS-BC (Hot Roller Sheet) is a type of flexible pavement construction because it uses asphalt as a binder between the aggregates. This study uses water hyacinth as a substitute for cellulose fiber in the mixture of HRS-BC. The purpose of this study is to determine the effect of water hyacinth cellulose fiber in HRS mixture to the Marshall characteristics. This research uses trial and error method, resulting 7.19 % asphalt content to the total aggregate weight with the variation of cellulose fibers are 3%, 4%, 5%, 6% and 7%. Marshall Test is performed to determine the effect of adding the cellulose fiber in the mixture to the components of Marshall Properties, for example Marshall Stability, % of Void Filed With Asphalt (VFWA), % of Void in The Mix (VIM), Plastic Fatigue (Flow), and Marshall Quotient (MQ).The result of this study is Marshall evaluation where the greatest score is obtained for stability of 1601 kg, flow of 4.60 mm, Quotient Marshall of 375.44 kg/mm, VMA of 20.45%, VFWA of 86.79 %, and VIM score of 4.19 %. It shows that the best cellulose fiber content is 3 % of asphalt level of 7,19 % and has been in accordance with Bina Marga 2010 Division 6 specification and can be used in asphalt mixture of HRS-BC.

Abstract

ABSTRAKSemen adalah suatu jenis bahan yang memiliki sifat adhesif dan kohesif yang memungkinkan melekatnya fragmen-fragmen mineral menjadi satu massa yang padat. Meskipun definisi ini dapat diterapkan untuk banyak jenis bahan, semen yang dimaksudkan untuk konstruksi beton adalah bahan jadi dan mengeras dengan adanya air yang dinamakan semen hidraulis. Hidraulis berarti semen bereaksi dengan air dan membentuk suatu bahan massa Komposisi kimia semen portland pada umumnya terdiri dari CaO, SiO2,Al2O3 dan Fe2O3, yang merupakan oksida dominan. Sedangkan oksida lain yang jumlahnya hanya beberapa persen dari berat semen adalah MgO, SO3, Na2O dan K2O. Variasi penambahan campuran serbuk kayu berpengaruh terhadap waktu pengikatan awal sedangkan pada waktu pengikatan akhir pasta semen tidak berpengaruh (ada pengaruh tapi sangat kecil) Penambahan prosentase serbuk kayu selalu menunjukan adanya penambahan terhadap waktu pengikatan awal maupun akhir pasta semen hal ini terlihat pada hubungan waktu ikat dan prosentase semen.Kata kunci: Beton Campuran,Serbuk kayu, Semen,Konsistensi semen, waktu ikat semen

Abstract

This research aims to determine how to make bricks with additive Zeolite with a composition of 14%, 16%, 18%, and 20%. This research method using the experimental method, this research concludes that red bricks are added with additive Zeolite with variations in the addition of 14%, 16%, 18%, and 20%. 2 samples were made for each additional percentage of Zeolite Additive, with the mold size according to the fabrication length 21 cm x 10 cm x 5 cm. By going through the drying process for approximately 14 days and burning for approximately 3 days. The resulting increase in compressive strength even though some of the variants experienced a decrease. The addition of the red brick variant with a composition of 0% produces an average compressive strength of 30.95 kg / cm2 . The 14% variant produces an average compressive strength of 35.71 kg / cm2, the 16% variant produces an average compressive strength of 40.48 kg / cm2, 18% and 20% variants produces an average compressive strength of 33.33 kg / cm2. The highest increase in compressive strength is the 16% variant, with an average compressive strength value of 40.48 kg / cm2

Abstract

However, flexible pavement has many disadvantages, such as early damage to the road surface after some time has passed by traffic so the road cannot reach the planned age. For this reason, a research was carried out to add hot asphalt mixture which aims to improve the quality of the mixture, the selected material is natural water hyacinth. The method used is trial and error with reference SNI 03-1737-1989. Variations used were 3%, 5%, and 7% of asphalt weight, the level of asphalt used was 4.48%. Of the 3 variations of the mixture used in Type I Asphalt Concrete Layer, the results obtained that the water hyacinth fiber content that has the best score and meet the specifications of SNI 03-1737- 1989 is the percentage of 7% obtained. from the calculation data using graphs and regression models where Marshall Stability is 889.73 Kg, VFWA (voids filled with asphalt) are equal to 65.97%, VIM (voids in mixtures) are equal to 1.757%, VMA (voids in mineral aggregates ) is equal to 20.30%, density 2.420 gr / cc, Flow 3.37 mm, and Marshall Quotient of 265.80 Kg / mm. Keywords : Flexible Pavement, Water Hyacinth Fiber, Marshall Test. Namun, perkerasan lentur memiliki banyak kelemahan, seperti kerusakan awal pada permukaan jalan setelah beberapa waktu berlalu lalang sehingga jalan tidak dapat mencapai usia yang direncanakan.

Abstract

In every construction work, you will find the remains of building materials no longer used and disposed of as waste, one of which is a ceramic waste. Ceramic waste is waste that has no selling value. Therefore the authors in this study will utilize ceramic waste as a substitute for cement with concrete quality K250. Several studies have also explained that ceramic waste contains silica, which has high adhesion, making it suitable as a substitute for cement. The process of mixing ceramic waste as a K250 quality concrete mixture is carried out according to the Indonesian SNI Standard and ASTM standards by laboratory testing using a variation of 3%, 4%, and 5% as a substitute cement. From these results, the composition of the addition of 3% ceramic waste has an average compressive strength of 330.99 kg/cm2, a composition of 4% has an average compressive strength value of 243.88 kg/cm2, and a percentage of 5% has an average compressive strength value 258.41 kg/cm2. The more the ceramic waste mixture as a substitute for cement, the lower the compressive strength of the concrete

Abstract

Housing is one of the most popular investment objects in Indonesia. According to the Residential Property Price Survey, housing sales were unstable in 2024. Given this condition, a feasibility study is required for housing projects under development in 2024, particularly for subsidized housing types with relatively low prices, which may result in narrow profit margins. This study conducted a feasibility analysis of the Ababil Land Babat Lamongan housing project, specifically for the 30/60 type unit. This research aims to gather information on the profit margin achieved by the company and the overall investment feasibility of the project, providing valuable considerations for companies or developers in their decision-making processes. The method used in this study is a financial aspect approach, including Net Present Value (NPV), Internal Rate of Return (IRR), and Benefit-Cost Ratio (BCR). The results show that the project yields NPV = IDR 115,222,182.95 > 0, IRR = 7.65% > MARR = 6%, and BCR = 1.031 > 1. Therefore, it can be concluded that the Ababil Land Babat Lamongan housing investment project is financially feasible.
