Abstract

Generally, cement factories produce secondary product in the form of split stone. Split stone products are produced from basalt rock crashed into aggregates of a certain size. This research is based on the results of split stone production, which is not following the target at a cement factory on the island of Sumatra. It creates production losses and financial losses. One of the causes of the incompatibility of the split stone production target is the non-optimal performance of the stone crusher machine. This research conducted a study related to the calculation of the stone crusher machine efficiency. Data in the real production capacity was obtained from recorded data in the field for twelve months. From the data obtained, the highest efficiency of the stone crusher machine of 58.32% occurred in the first month with a total production loss of 1,086 tons or equivalent to Rp. 217,296,000. The lowest efficiency of the stone crusher of 3.52% occurred in the eighth month with a total production loss of 12,133 tons or equivalent to Rp 4,478,112,000.

Abstract

The braking system is one of the crucial components in a vehicle because braking is a vital safety feature of the vehicle. The braking system functions to reduce or slow down the speed and stop the vehicle, as well as to enable the possibility of parking the vehicle on a downward slope. The braking system under investigation is examined in the prototype vehicle called Gardapati, which employs a hydraulic brake system. Gardapati is a vehicle created by students from the University of Riau's Mechanical Engineering Department, affiliated with the UKM Selembayung, following the standard references provided by the Energy-Efficient Vehicle Competition organized by BPTI. This final project will involve several calculations related to the braking system, following the specifications used in the Gardapati vehicle. First, calculations will determine the dynamic braking force required (Fb) when the vehicle is moving at a speed of 50 km/h with a distance of 20 meters, as well as the static braking force (Fb) required when the vehicle is on an incline of 11.2 degrees, adjusted to the requirements and regulations of the 2023 Energy-Efficient Vehicle Competition (KMHE). Then, the braking distance will be calculated for speeds of 30, 40, and 50 km/h on dry and wet asphalt road conditions. From the calculation results and data analysis, it is found that the required dynamic braking force (Fb) is 510,76 N, and the static braking force (Fb) is 830,31 N. Meanwhile, the minimum braking distance is observed on dry asphalt road conditions at a speed of 30 km/h with a percentage error of 1,59 %, where the theoretical value is 5.67 m and the actual value is 5,76 m. On the other hand, the highest braking distance is observed on wet asphalt road conditions at a speed of 50 km/h with a percentage error of 7,39%, where the theoretical value is 14.47 m and the actual value is 15.54 m. Of the two road conditions, the largest percentage error occurs when testing the vehicle at speeds of 30, 40, and 50 km/h on wet asphalt conditions, amounting to 4,61%. With this level of percentage error, it can be concluded that the variation in the obtained data is relatively small, which is less than 10%.

Abstract

Potensi objek wisata yang terdapat di Batu Bersurat belum tergarap dengan serius dan maksimal. Hal ini dapat dilihat dari minimnya sarana informasi dan promosi terkait keberadaan objek wisata di wilayah ini. Selain itu, minimnya keberadaan sarana pendukung turut menjadi penyebab rendahnya kunjungan wisatawan di wilayah ini. Berdasarkan pada permasalahan tersebut. Tim melaksanakan kegiatan pengabdian dalam bentuk pengembangan sarana dan penyediaan akses informasi wisata dalam rangka meningkatkan minat dan kunjungan wisatawan di Kelurahan Batu Bersurat, Kabupaten Kampar. Kegiatan pengabdian ini diawali dengan pembuatan foto udara dan foto landscape di area wisata Batu Bersurat dengan menggunakan wahana pesawat terbang tanpa awak tipe fixed wing. Selanjutnya kegiatan dilanjutkan dengan pembuatan video udara sinematik dengan memanfaatkan dua unit pesawat tanpa awak tipe rotary wing (drone). Hasil dari pembuatan media promosi wisata berbentuk video udara sinematik, foto landscape dan foto udara, selanjutnya diintegrasikan ke dalam media informasi wisata berbasis website yang juga dibuat oleh tim pengabdian. Diharapkan dengan adanya media promosi dan media informasi wisata ini, memudahkan pengelola objek wisata di Batu Bersurat, untuk mempromosikan ke khalayak ramai terkait keindahan objek wisata yang terdapat di Batu Bersurat.

Abstract

Fiberglass is the most common reinforcing fiber used in composites, with polymer matrices having high tensile strength and chemical resistance, including an excellent insulating property; however, they are non-degradable. Natural fiber reinforced polymer composites have advantageous properties such as lower density and price, when compared to synthetic composite products. In addition, hybrid composites may be obtained depending on various properties such as the fibers' length, structure, content and orientation, matrix bonding and arrangement. This study was carried out to determine the effect of adding Maleated Natural Rubber (MNR) from natural rubber as a coupling agent, in order to produce the highest tensile and flexural strength. The hand lay-up and vacuum bag methods with the Response Surface Method-Central Composite Design (RSM). -CCD) were used. The composite arrangement pattern was E-glass/OPEFB/E-glass, the volume fraction of OPEFB (oil palm empty fruit bunches):E-glass was 40:60, 50:50 and 60:40, the fraction volume of OPEFB + E-glass:matrix was 40:60, 50: 50, 60: 40 and the coupling agent were added by 9, 10 and 11% of the total epoxy resin used. Furthermore, the composite mold was made of glass with dimensions of 200mm x 50mm x 50mm. The results showed that the composite product obtained from both methods had a tensile strength value, which was influenced by the variable OPEFB fiber and epoxy resin. Meanwhile, the flexural strength was influenced by the OPEFB fiber and the quadratic factor of the epoxy-MNR resin.

Abstract

Translational motion that happens in the vehicle's suspension due to unevenness of the road surface can be used as a source of electrical energy. A suspension that can convert translational motion into electrical energy is known as regenerative type suspension. To know the characteristics of the dynamic response, such as electrical energy potential and driving coziness which resulted by a suspension system, we need to examine the suspension. In this study, a test will be conducted to a suspension system that has been designed by researchers and was named Hydraulic Motor - Regenerative Shock Absorber (HMRSA). The test will be conducted statically and dynamically. The goal of the static testing is to obtain the spring's constant value and the damping's constant value of HMRSA. In the dynamic testing, excitation was given in the form of periodic and impulse. Periodic excitations are varied between these several frequencies such as 1.4Hz, 1.75 Hz and 2 Hz. Instead of variant of frequencies, electrical resistivity loads are varies in periodic excitations with each resistive loads such as 6 ohm, 12 ohm and 18 ohm. From dynamic testing, the electricity power values and sprung's mass acceleration which resulted by HMRSA suspension system on each frequency and electrical resistivity will be obtained. The sprung's mass acceleration value will be fundamental on how to analyze driving coziness that produced by HMRSA suspension system.
