Abstract

Kinematics analysis includes analysis of position, velocity and acceleration of the rods of a mechanism. The complex number method is a kinematic analytical way to express position, velocity and acceleration vectors in the form of complex numbers. The first step that needs to be done is to determine the position vector of the point to be analyzed, then determine the velocity and acceleration vectors by differentiating with time. After that is done, then the algorithm can be made. The mechanism used for this study is the quick return mechanism. The assumed data for this analysis is the angular velocity of rod 2 is 19.0986 rpm and the acceleration of rod 2 is 0 rad/s2. The results of the position analysis show that if rod 2 rotates one full rotation (360o), then rod 4 rotates about 1/6 circle (232.72o - 294.12o) and the slider moves along the X axis (406.939 - 504.111). The maximum speed behind the slider is 121.45 mm/s while the maximum speed forward for the slider is 101.09 mm/s. A large change in velocity (acceleration) is needed when bar 4 and the slider change direction (from CW to CCW or vice versa), this is indicated by a decrease and increase at the beginning and end of the graphic with significant acceleration

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

Tingginya jumlah limbah sagu yang dihasilkan di sentra-sentra produksi sagu di kabupaten Kepulauan Meranti masih belum dimanfaatkan secara optimal dan banyak yang dibuang ke perairan sehingga dapat menyebabkan pencemaran lingkungan. Salah satu upaya yang dapat dilakukan untuk mengurangi pencemaran lingkungan akibat dari limbah sagu yaitu dengan cara memanfaatkannya sebagai bahan baku alternatif dalam pembuatan pakan ikan. Tujuan dari kajian ini adalah untuk mengetahui potensi limbah sagu di kabupaten Kepulauan Meranti, membuat formulasi pakan ikan dengan bahan baku imbah sagu, dan melakukan uji pertumbuhan ikan menggunakan pakan campuran limbah sagu. Data primer diperoleh dari observasi di lapangan, analisis di laboratorium, dan pengujian pertumbuhan ikan. Produksi sagu di kabupaten Kepulauan Meranti sekitar 198,162 ton/tahun dengan limbah padat berupa ampas sagu sekitar 14% dari total produksi. Ampas sagu tersedia secara kontinyu sehingga memungkinkan untuk digunakan sebagai bahan baku pembuatan pakan ikan. Hasil analisa proksimat ampas sagu dalam bobot kering menunjukkan bahwa kadar protein ampas sagu relatif rendah, berkisar 0.96 – 1.01%. Ampas sagu dapat menyediakan energi relatif tinggi dari karbohidrat dalam bentuk bahan ekstrak tanpa nitrogen (BETN) dengan kandungan berkisar 72.13 – 80.76%. Hasil ujicoba menunjukkan bahwa dengan menggunakan pakan dari ampas sagu, pertumbahan bobot ikan nila lebih besar yakni 26.5 g dibandingkan ikan lele dumbo hanya 1.2 g. Dengan demikian ampas sagu dapat dimanfaatkan untuk ikan herbivora dalam jumlah lebih banyak dibandingkan untuk ikan karnivora.

Abstract

Agave Sisalana is widely grown in the Bukit Bulek area, West Sumatra Province. The Sisal leaf fiber is traditionally utilized by the Bukit Bulek community as a rope material. This indicates it has a great potential to be developed as a composite reinforcement material. This research aims to characterize the flexural and impact strength of Sisal leaf fiber as reinforcement in epoxy matrix composites by varying the fiber volume fractions, 30%, 35%, 40%, and 45% with a 0°/90° fiber orientation laminate. The 20 cm long of fibers and treated with 5% NaOH alkaline solution for 4 hours were employed. The composites were fabricated using the vacuum bagging method. Flexural and impact tests were conducted based on ASTM D-790 and ASTM D-6110 standards, respectively. The results show that the flexural strength increases from 45,20 to 49,67 MPa (maximum) as the fiber volume fraction increases from 30% to 35% fiber. Meanwhile, the impact strength increases as fiber volume fractions from 30% to 45% and reaches a maximum impact strength of 24.60 kJ/m².

Abstract

The Menaming Dam is located in Menaming Village, about 3 km away from residential areas, so it is far from the reach of electricity service providers. From the dam, the water is distributed through irrigation canals to the rice fields and fishery and contains hydraulic power, then could be utilized for electricity generation. The location of the dam has attractive views so that it becomes tourism, but there is no electricity available, causing its development to be hindered. Utilization of water resources in irrigation can be done by developing a waterwheel as driving for electricity generators. The power plant with an undershot waterwheel is very suitable to be developed because it is easy to manufacture and maintain. Besides that, the structure and shape can add to the beauty and attractiveness of visitors to tourist sites. Now a hydroelectric power plant has been installed with a total power of about 70 W. Electricity is transmitted using cables through the power poles and an LED light is installed on each of them. Furthermore, in one of the stalls in the tourist location, the installation of lights and sockets for charging mobile phones was made. Lights were also installed in an adjacent house.
