Pengaruh Penambahan Filler Al2O3 dan TiO2 pada Resin Polyester terhadap Sifat Fisik dan Mekanik
Get PDFPolyester composites have been developed to have high strength and light density, but the fracture occurs due to very little plastic deformation or low strain values, pre-failure detection is difficult in these composites due to the rapid propagation of cracks in the composite system. To increase the strength and delay failure, the addition of filler in the form of Al2O3 and TiO2 particles is carried out. The use of particles as fillers in polymer composite materials is increasingly being developed. In this study, Al2O3 and TiO2 particles (0%, 2%, 4%, 6%, 8%, 10% vol.) were added in polyester matrix BQIN EX 157. by casting method; the liquid homogeneous mixture was carefully poured into a simple mould to be air dried. The composites were cut to serve as specimens for density test, mechanical tests such as tensile and compressive tests. The results showed a density of 1.23 g/cm3, a maximum strength of 47 MPa for 2% additional Al2O3 filler, (tensile, decreasing ̴11%) and 120 MPa (compressive) for a maximum of 2% additional Al2O3 (compressive, decreasing ̴3%) with TiO2 filler. The decrease in strength was caused by uneven particle dispersion, voids and agglomeration that occurred during the casting process

Optimasi Pemanfaatan LPG Sebagai Bahan Bakar Genset Untuk Mendukung Program Penghematan Energi
No full textThe use of LPG as a generator fuel needs to be optimized. For this reason, the correct LPG gas flow rate needs to be studied so that it becomes economical. The purpose of this study is to analyze the effect of fuel flow rate variation and Choke Valve variation on the performance of a 4-stroke generator. Gas enters the carburetor with varying gas flow rates of 3 L/minute, 4 L/minute, 5 L/minute and 6 L/minute. Then the generator is set to run stably on fully open, half and closed Choke Valve variations. From these variations, a combination is then sought to produce the smallest LPG flow rate with optimum power. The generator can operate well at flow rates of 4 L/min and 5 L/min with the Choke Valve variation position fully open. This shows that the ratio of LPG and air reaches the ideal condition so that the combustion process is complete. Optimization of LPG consumption in the generator is set at a flow rate of 4 L/minute with the Choke Valve fully open. Thus the excessive use of LPG can be saved

Get PDFParkir merupakan bagian dari fasilitas yang menyatu dari sistem jalan secara keseluruhan. Parkir merupakan permasalah umum pada transportasi perkotaan, baik di kota berkembang maupun di kota besar. Masalah parkir juga merupakan sesuatu yang tidak dapat diatasi oleh beberapa fasilitas umum seperti rumah sakit. Penelitian ini bertujuan untuk mengetahui karakteristik parkir dan manajemen perparkiran. Penelitian ini dilakukan dengan cara survei pencacahan langsung dilokasi Rumah Sakit Tentara Kota Solok. Dari hasil analisa yang dilakukan di area parkir Rumah Sakit Tentara Kota Solok (On Street Parking), didapatkan akumulasi parkir untuk kendaraan roda dua selama 4 hari dalam interval waktu 15 menit didapatkan jumlah kendaraan yang tertinggi pada hari Rabu sebanyak 110 kendaraan dengan 80 SRP, sedangkan untuk kendaraan roda empat sebanyak 26 kendaraan dengan 18 SRP oleh karena itu permintaan kebutuhan ruang parkir tidak dapat dipenuhi karena kapasitas ruang parkir yang tersedia tidak mampu untuk menampung kendaraan pengunjung rumah sakit, sehingga perlu penambahan untuk memenuhi kebutuhan parkir pada jam puncak atau pada waktu akumulasi parkir maksimum yang sesuai dengan Pedoman Teknis Penyelenggara Fasilitas Parkir dengan jumlah tempat tidur 80 maka jumlah SRP yang dibutuhkan sebanyak 104 SRP. Dari 100 responden yang mengisi kuesioner, rata-rata dari 8 pertanyaan mengenai kenyaman, keamanan dan operasional responden memilih cukup. Dengan adanya masalah parkir dibahu jalan sebaiknya pengatur parkir perlu dikembangkan terutama pada waktu sibuk kendaraan memasuki area agar tidak mengganggu siklus kendaraan lainnya, perlu diberi batasan-batasan parkir seperti petak-petak parkir sehingga tidak ada kendaraan yang parkir sembarangan dan memberikan rekomendasi kepada pihak Rumah Sakit Tentara Kota Solok untuk menyediakan lahan parkir yang memadai sesuai dengan Direktur Jenderal Perhubungan Darat 1996 yaitu sebanyak 104 SRP
Photogrammetry Technology by Using DJI Phantom 4 RTK in Batang Mahat, Lima Puluh Kota Regency West Sumatera
Get PDFTechnological developments in the field of engineering have increased rapidly. The use of geospatial information becomes one of the bases for decision-making related to planning, managing, and evaluating a field, especially in engineering, which includes the field of measurement and making topographic maps or Digital Elevation Model (DEM). High-resolution geospatial information can create a high-resolution Digital Elevation Model (DEM) map that can be very useful in making models or maps of flood-affected areas. This research will use the photogrammetry technology with DJI Phantom 4 RTK to create the DEM data of Batang Mahat located in Lima Puluh Kota Regency, West Sumatra Province. 28 flights at predetermined points had carried out to measure the area of about 9 km2. All the results of photos captured by the drone will be imported to Agisoft Metashape 1.8.2 software to create the DEM data. The DEM was then compared with DEM data from DEMNAS and the measurement data of Batang Mahat by the SDABK office. The result shows that photogrammetry technology using DJI Phantom 4 RTK compared to measurement data and DEMNAS have a similar ground elevation but different river elevation. This is because the photogrammetry by using DJI Phantom 4 RTK is not equipped with LiDAR. An alternative to solve the problem is by combining the DEM data by DJI Phantom 4 RTK with data from terrestrial surveys. However, this method is quite expensive and ineffective in analyzing flood inundation compared to DEM data (8 m resolution) from DEMNAS
