Pengaruh Penggunaan Zat Aditif Grolen Hp19r Terhadap Beton Mutu F´C 25 Mpa
Full text linkThis research aims to process additives as additional ingredients for concrete mixtures, which aims to maintain the quality of concrete. In this research, the researchers tried to change the composition of the concrete by adding the Grolen HP19R additive to the compressive strength test of FC 25 Mpa concrete to obtain further results in accordance with the compressive strength determined as a reference material. The concrete mixing method uses Grolen HP19R additives using a job mix design fc 25 Mpa which is added to the concrete mixture with variations of 0.4%, 0.6%, 0.8% and 1% of the weight of the cement used. The concrete is cured for 3 days and 28 days then tested to obtain the slump value, compressive strength value and unit weight of the concrete.
From the tests carried out, it was found that the maximum slump value was found in the concrete added with 0.8% BN+Grolen HP 19R compared to normal concrete with a value of 612.50%. Grolen HP19R can increase the density of concrete with a maximum weight at 28 days, namely the BN+GR 1% variation with a value of 2809. Grolen HP 19R also increases the compressive strength value of concrete aged 28 days with a maximum value found at BN+GR 1% with a result of 414.66 %
Studi Eksperimen Pengaruh Kemiringan Seawall Tipe Bertangga Terhadap Redaman Gelombang (Studi Kasus: Pantai Kuala Penampar Jangkang)
Full text linkKuala Penampar Jangkang Beach has experienced a lot of damage to coastal protection structures due to large waves. The problems that occur need to find a solution on how to avoid overtopping of the revetment building which results in the construction becoming unstable or even destroyed. In this study, the researchers redesigned it by conducting experimental tests on the seawall model at Kuala Penampar Jangkang Beach using lightweight concrete base material with modifications to a scale of 1:10 to the actual size, and physically modeling it in a flume tank in the laboratory with variations in the slope of the seawall structure in order to to find out which structural slope is more efficient in reducing overtopping. From the experiments that have been carried out, it can be concluded that the smaller the slope angle or the steeper the slope of the seawall, the smaller the wave run-up (Ru) produced. The largest wave run-up (Ru) at a slope angle of 1:2 is 1.34 m, while at a slope angle of 1:3 the lowest is 0.86 m with a wave height of 0.8 m and a period of 2.3 seconds

Perubahan Garis Pantai Akibat Breakwater (Studi Kasus : Bagian Kiri Breakwater Di Pantai Raja Kecik Desa Muntai)
Full text linkChanges in the Coastline due to Breakwater. Bengkalis Island is one of the archipelagic areas in Bengkalis Regency. Because it is directly facing the open ocean, over time there will of course be changes in the physical condition of the beach due to the dynamic nature of the beach, where these changes can be in the form of erosion and sedimentation The Raja Kecik Beach area is one of the tourist destinations on Bengkalis Island. This area is protected by coastal buildings such as breakwaters which are the case study for this research. The author conducted research at Raja Kecik Beach to determine changes in the coastline caused by breakwaters and changes in sediment in the breakwater area. This research was carried out with a direct field survey. The results of observations showed that after the results of the first, second and third measurement data, it was discovered that the largest sedimentation was in longsection 2 with a volume of 8,632 M3 and the smallest was in longsection 16 with a volume of 5.56 M3
Aplikasi Pencarian Bengkel Dan Pemesanan Servis Sepeda Motor Berbasis Website
Full text linkPeople around Bengkalis Island often face various problems related to motorbike maintenance and repair, especially riders from outside the area. There are several problems experienced, such as flat tires, engine damage, and difficulty finding a repair shop while traveling, which often become annoying problems. Apart from that, long queues at workshops often make motorists feel uncomfortable and bored. Currently, workshops on Bengkalis Island still use a conventional system where customers have to come directly to the location to get service, even though technology has become more advanced and many people are used to using smartphones. To overcome this problem, the proposed solution is a website-based Motorcycle Workshop Search and Service Order Application. This application will help users find the nearest repair shop, know the location accurately, and provide rating information from previous customers. With this application, it is hoped that the motorbike maintenance and repair process will become more efficient and comfortable for riders, especially for those who are not familiar with the Bengkalis Island area
Website Pendaftaran Antrian Praktik Dokter Mandiri
Full text linkIn Bengkalis, Dr. Madya Ulfah Danial's independent paediatrician practice has irregular queues. A website is proposed to help solve this problem. It will allow patients to register from home and create a more organised queue. This website aims to develop an online registration system that can simplify the registration process, and improve the service experience. The website features a queue list on the patient page so that patients can see their queue order. Quota feature, with this quota feature patients can find out the registration limit and the remaining quota available to register. testing this system using the black box method to show the test results that al
