Abstract

Lapis Pondasi Aspal (Aphalt base) adalah bagian dari lapis perkerasan aspal, yang berada dibawah lapisan aus (wearing course) dan lapis antara ( binder course. Dalam hal ini jenis campuran Aspal Base yang d iteliti yaitu HRS-base yang dicampur dengan getah karet (lateks). Penelitian ini bertujuan untuk mengetahui sejauh mana tingkat keelastisan dan kekakuan aspal setelah dicampur getah karet. Penelitian ini dilakukan dengan kadar aspal 6% dan kadar Lateks 0%, 0.5%, 0.75%, 1%, 1.5%, dan 2%. Penelitian ini dilakukan di Laboratorium Sabaritha Perkasa Abadi (SPA) Jalan Tambusan Merek. Penelitian ini dilakukan dengan langkah yaitu Persiapan Benda Uji, Gradasi Agregat, dan Melakukan Marshall Test. Berdasarkan hasil penelitian yang telah dilakukan penambahan getah karet optimum yang dapat digunakan dalam campuran adalah variasi getah karet 0.5%, 0.75%,1% dan 1.5% karena memiliki nilai stabilitas tinggi dan nilai rongga dalam campuran (VIM) rendah, tapi variasi getah karet yang paling baik digunakan yaitu variasi getah karet 1.5% karena variasi tersebut memiliki nilai stabilitas paling tinggi dan nilai rongga dalam campuran paling rendah , nilai stabilitas tinggi mengindikasikan tingkat kekuatan Lataston HRS-BASE terhadap kemampuan menahan beban.Sedangkan nilai rongga dalam campuran rendah mengindikasikan ketahanan aspal terhadap genangan air. Pencampuran Aspal dengan Lateks dapat dijadikan solusi untuk jalan raya yang menerima beban berat dari kendaraan dan juga mampu mengindikasikan ketahanan aspal terhadap genangan air dikarenakan curah hujan di Indonesia tinggi.

Abstract

Contractors in the construction sector have reduced the cause of their profit, namely the large costs incurred for purchasing construction materials. In utilizing material from construction that is not only for reducing costs incurred, it is more in profit in the project being implemented. The effort used to reduce waste is to use Lean construction (lean construction). The purpose of this study was to analyze the amount of waste generated from the implementation stage of the Sidilanitano irrigation network construction project in North Tapanuli Regency. So that the impact on mitigation is carried out in order to maximize the profit value of the contractor. This research method is a descriptive method and analysis is carried out directly at the project site. Data collection was carried out by field observations, interviews. The results showed that the material that caused waste cost was Pek. Reinforcement, Pek. Formwork and Dismantling Formwork and Pek. Cast Concrete K. 225. The level of application of lean construction in the Sidilanitano irrigation project in North Tapanuli Regency is not yet fully effective. However, the rest of the project material has been optimally carried out by the contractor to a minimum. Where the remaining 50 cm of iron material is stored while smaller sizes are sold. The rest of the concrete material is used to cover the stagnant roads around the project.

Abstract

Personal protective equipment is part of the prevention of accidents and occupational diseases. Seeing that the benefits of PPE are very important for workers, it is necessary to review the behavior of workers using PPE in industry. The purpose of this study is to look at the factors that influence workers in using PPE, which later results from the analysis can be used as a basis and reference for academics and practitioners in the application of occupational health and safety culture in industry, especially in the use of PPE. The research method used is Literature Review, data collection is carried out by internet searches through Google Scholar, Researchgate, and ProQuest with the keywords Personal Protective Equipment, PPE, Industry, PPE, and industrial. The articles used are articles in the 2016-2020 timeframe. The initial search results for articles found 1,432 but after screening based on predetermined inclusion criteria, 15 articles were selected consisting of 13 Indonesian articles and 2 international articles. The conclusion obtained in this study is that there are several factors that influence the behavior of workers in using PPE, namely predisposing factors between other attitudes, knowledge, and comfort in using PPE. Driving factors include training, supervision, and policies or regulations. Supporting factors include social support and the completeness of the PPE used.

Abstract

In the implementation of construction, the weakening of structure occurs very frequently. This condition is shown through the crack on the plate floor, on the beam or on the column. This structure weakening is frequently caused by wrong design, the change of the function of the building, or natural factor. To maintain the structure of building, reinforcing is very frequently done on the area of experiencing the weakening process.The result of the experiment value was compared through numerical method to obtain the pattern of crack or the increase of load value that can be carried by the beam after being reinforced. That with this simulation, the writer expects that the reinforcement done to the beam especially the one with fricative crack can be accurately and well implemented.

Abstract

Foundation work is an initial job that is usually done by all engineers in the construction of structures. Beginning with a soil investigation survey, then identification of the type and strength of the soil is carried out to determine the type of foundation that is suitable for the structure. In planning the foundation in building construction, it is necessary to investigate the soil parameters used in the calculation of the bearing capacity of the soil. The bearing capacity of the soil is very influential on the type and dimensions of the foundation, especially regarding the load carried by the foundation to be planned. A foundation is part of an engineering system that transmits the load supported by the foundation and its own weight to and into the soil and rock that lies beneath it. The resulting soil stresses except at the soil surface are in addition to the loads already present in the soil mass from its own weight. The borepile foundation made was 181 piles and the tested piles were 3 piles or 3/181 = 1.7%. The weight of the hammer used should be = ultimate bearing capacity *1% = 244.45 x 1% = 2.5 tons. While the weight of the hammer used in the field is 2.5 tons, meaning that it is sufficient. Hammer fall height = 1 – 1.2 m, so the hammer impact energy efficiency is 3.3-18%. For hammer impact energy efficiency for B-3 piles of 3.3% is considered inadequate.

Abstract

Designing on the Waste Water Treatment Plant, often overlooked by variations in water pressure at the time of empty water reservoirs suddenly, so the designing often assumes that the water load is a static load.The case reviewed on the WWTP wall structure is evident that water also has unique behavior especially in large structures. Careful planning certainly will not lead to anything like the case occurring in this research review.The repair or reinforcement analyzed through the Hydro Test testing behavior concludes that without dismantling the entire building, it can still revert to the planned needs of the WWTP building structure.The analysis performed using the finite element method tool to speed up the calculation states that by increasing the number of existing reinforcement can improve the ability of WWTP structure.

Abstract

The aim of the study was to determine the effect of organic and inorganic fertilizer application on the growth and production of the Batu ijo variety shallots. This research was conducted on the land of UPT Seed Parent Horticulture Kutagadung Berastagi, Berastagi District, Karo Regency, North Sumatra, from June-August 2019. The study used a Factorial Randomized Block Design (RAK) method which consisted of two treatment factors, the first was the dose of Source Organic fertilizer. Sustainable Nature“O” 4 levels: (O0) control, (O1) 270 grams/plot, (O2) 540 grams/plot and (O3) 810 grams/plot. Second, the dose of NPK Mutiara fertilizer with the symbol M consisting of 4 levels: (M0) control, (M1) 44 grams/plot, (M2) 87 grams/plot and (M3) 130 grams/plot, in order to obtain 16 treatment combinations and 2 blocks. The data from the observations were then analyzed for variance with the F test at 5% level and the DMRT test. The results showed that the treatment with Sumber Lestari Alam organic fertilizer had a significant effect on plant height/sample (cm), number of leaves/sample (cloves), number of tillers/sample (stem), number of tubers/sample (cloves), tuber diameter/sample. (mm), and crop production/sample (grams). The treatment of NPK Mutiara fertilizer had no significant effect on the parameters of plant height/sample (cm), number of leaves/sample (cloves), number of tillers/sample (stems), number of tubers/sample (cloves), diameter of tubers/sample (mm), and crop production/sample (grams).
