Abstract

Biogas is a gas produced from the fermentation process of organic materials bymicroorganisms in closed conditions (anaerobic). Biogas consists of ± 60% CH4 (methane), ±38% CO2 (carbon dioxide), ± 2% N2 (nitrogen), O2 (Oxygen), H2 (hydrogen), and H2S(hydrogen sulfide). In this research, the making of biogas uses raw materials from cow dung.Cow dung is the right raw material because it contains methane-producing bacteria. Thisresearch aims to determine the influence of the EM4 addition of biogas quality produced. Thisresearch was conducted in the Basic laboratory system of energy generation of the SurabayaState Polytechnic electronics. The method of the research is to use a comparison of cow andwater in raw materials, with a ratio of 1:1 with the addition of EM4 (Effective microorganism)as much as 3 liters on variations of 1 and 1.5 liters on variation 2. Biogas making is carried outon the digester with a volume of 200 liters with a batch system with stirring 3 times a day withfermentation for 25 days. The result of this research is with the addition of EM4 as much as 3liters produce biogas with methane gas content with the amount of 53.6%. The resulting biogascombustion test has a yellowish blue flame, a long flame of 56 seconds. While the addition ofEM4 with a total of 1.5 liters produces biogas with methane gas content with the amount of46.8% yellow flame color with a long flame of fire for 34 seconds

Abstract

Water is a fundamental human need. One effort to obtain a constant water supply is by pumpingmethod. The Hydram pump is one of the alternatives that can be used to meet these needs. Inaddition to cost-effective, this pump is also very simple in manufacturing, assembling, andoperation. The installation components of the hydram pumps consist of water tanks, input pipes,output pipes, exhaust valves, sender valves, and air tubes. The workmanship of this final taskwill be measured the number of discharge pumping, tapping the exhaust valve, pressuredischarge, D'aubuisson efficiency, and hydram pump efficiency to the height variation of thereservoir and discharge input. On the workmanship of this final task will be used the hydrampump with specification: 1-inch input pipe diameter, the output pipe diameter of 0.75 inches, thediameter of air tube 2 inch, high air tube 0.75 m, and heavy exhaust valve load 0.4 kg.Variations in working conditions that will be tested on the Hydram pump are high reservoir (1m, 1.25 m, 1.5 m) and discharge input (10 LPM, 12 LPM, 14 LPM). From the experiments thathave been carried out the highest pumping discharge of 2.1 LPM at an altitude of 1.5 m with aninput discharge of 14 LPM. The large pressure discharge value that occurs during the workingcycle of the hydram pump is directly proportional to the reservoir height. Best hydram pumpperformance is obtained at 1.5 m altitude variation with 14 LPM input discharge where theefficiency of D'aubussion is 44.06% and the efficiency of the Hydram pump 29.91%.

Abstract

Competition in the manufacturing industry demands products with high quality and high productivity too. Machining parameters such as cutting angle, cutting speed, and feed speed determine the rate of material works or the rate of material removal (MRR) of the lathe process. Determination of excessive machining parameters will reduce productivity because there is a product that must be reworked. This research will specifically emphasize the lathe process with medium carbon steel workpieces. The problem is how to specify its cutting speed, feed speed, and the primary cutting angle in the lathe process with a medium carbon steel workpiece that will produce a smooth surface of the lathe on the product. The workpiece used in the experiment is ST 60 steel dimensions Ø30 mm x 200 mm with a chuck-tailstock spindle gripping system. The results showed that the ST-60 steel lathe process without followers, with the primary cutting angle machining parameters Kr = 45°, cutting speed 60.5 m /min, feeding speed 44.66 mm/min, and at a depth of cut 0.2 mm obtained surface roughness value 3.72 μm or N8 roughness level. As for the primary cutting angle machining parameters Kr = 90°, cutting speed 60.5 m/min, feeding speed 22.33 mm/min, and at a depth of cut 0.2 mm, the surface roughness value 3.69 μm or N8 roughness level is obtained.

Abstract

The utilization of biomass as an alternative to reduce dependence on fossil energy can be done through briquette technology. Through this technology, alternative energy sources can be obtained with high heating value and easy storage. The current promising source of biomass is sawdust and coconut shell waste because it is available in abundant quantities. This abundant amount has not been optimally used, because it only tends to be burned. Through briquette, technology is expected to increase the added value of waste. Briquette quality is influenced by several factors, one of which is the particle size of charcoal powder. The purpose of this study was to determine the effect of particle size of charcoal powder on the content of fixed carbon and volatile matter on charcoal briquettes. The research method was carried out by varying the particle size of charcoal powder, 10 mesh, 20 mesh, and 40 mesh. The research was carried out in several main stages, there are charcoal (carbonization), particle size reduction (grinding), sieving, mixing of raw materials, molding, drying, and testing of charcoal briquettes. The results showed that the charcoal briquettes produced had an average fixed carbon content of 58.761% and a volatile matter of 33.675% at 10 mesh charcoal powder particle sizes. At a particle size of 20 mesh, it produces charcoal briquettes with an average fixed carbon content of 60.491% and a volatile matter of 31.333%. While at 40 mesh, it produces charcoal briquettes with an average fixed carbon content of 59.216% and a volatile matter of 30.561%. The research results obtained further reinforce that the charcoal briquettes produced are feasible to be developed.
