Gas Fuel

Converter kits are equipment used to translate fuel oil (CNG) into gas fuel (CNG) in convertible vehicles. The use of a converter kit with CNG liquefied petroleum gas (LPG) will be used to optimize engine performance while driving, but its use is not yet known among the public because it is not affordable and there is no transition from fuel to consumed gas. Therefore, it is necessary to design a simple converter kit, affordable by the community, and can be supported on two different fuels. This study redesigned the manual converter kit with a research focus on aluminum gas mixer components with variations in the number of intake mixers (1, 2, and 3) and added mixing zones in the mixer area, using 110 cc single cylinder motorized engine with carburetor fuel system with a variation of 1500-9000 rpm. Engine performance testing is done using a chassis dynamometer. The use of LPG fuel in various types of input mixers is able to increase torque and power on the engine. Engine performance test data shows that the best torque value on the use of LPG materials in input mixer 1, 2, and 3 holes respectively are 17.44 Nm, 16.77 Nm and 11.71 Nm, while for gasoline fuel is 16 Meanwhile, the value of power in the use of LPG fuel with the input of mixer 1, 2 and 3 holes is capable of producing maximum power respectively 7.1 Hp, 7.4 Hp and 7.3 Hp, while for gasoline fuel at 7.7 Hp. The use of LPG fuel with the number of 1 hole mixer input is the best variation compared to gasoline fuel and the number of mixer inputs in the other variations.

A Value

Fuel is something that is very important in everyday life. Almost every human being needs fuel to meet their needs and support their activities, for example cooking in household needs. Currently, fossil fuels or fuel oil (BBM) are still widely used to meet demand, however, it should be noted that fossil fuels or fuel oil (BBM) are non-renewable natural resources. The biomass rocket stove is one of the modern stove innovations that uses biomass energy as the main energy source. Rocket stoves are designed to increase fuel efficiency with thermal efficiency, a combination of the increased combustion efficiency and heat transfer associated with burning briquette fuel. The purpose of this research is to design and manufacture rocket stove fired with coconut and bamboo biomass for household needs as well as developing methods and equipment for performance testing of rocket stoves. In this study, several steps were carried out, including designing a rocket furnace, selecting biomass fuel and testing the performance of a rocket furnace. From the design of the biomass stove, it is noteworthy that the design with two holes makes the combustion air easily enters and makes combustion in the furnace more perfect and efficient. Water boiling test using three types of solid fuels with the cold start condition suggested that the highest thermal efficiency was coconut fronds with a value of 38% and the lowest thermal efficiency was found from coconut shell combustion, i.e. 22%. During hot start test, the highest thermal efficiency was obtained from coconut fronds firing with a value of 41%. Moreover, with simmer water boiling test method, firing the rocket stove with coconut fronds showed the highest thermal efficiency with a value of 37%.

ABSTRACTGarbage is solid waste, consisting of organic and inorganic substances or materials that are considered to have no longer beneficial and must be managed properly so as not to endanger the environment. Garbage has been a complicated problem especially in big cities. Singaparna, Tasikmalaya  has been produced 154.72 m3 of plastic waste every day. Plastic waste collected by BST is only sort and sold at low prices to the city. To increase the sale value, the plastic waste needs to be chopped in advance. Therefore, the Laboratory of Agricultural Equipment and Machinery FTIP Unpad had developed a plastic waste counting machine to be applied to the community, especially in BST to produce the desired plastic count. However, this machine not yet performance testing data, so it needs to do research regarding performance tests. The purpose of this study is to examine the performance of the plastic counter machine which includes measuring the capacity of the machine, calculating the rendering yield, calculating the length of the enumeration measuring the engine noise level and measuring the engine vibration level. The research method used had descriptive analysis method, it was measuring and calculating the structural components and engine performance. The results of the study in measuring the performance test showed that the actual capacity of the machine was 19.18 kg / hour, the enumeration chopper was 84%, the percentage of plastic chopping length was 86.89%, the noise level was 104.77dB, and the engine vibration was 18.3 mm / s. Key Note : plastic chopper, performance test, tasikmalaya garbage bank

Expected Values

Performance testing of gas turbine packages is becoming increasingly common to assure that the turbine output power and efficiency meet the expected values during the turbine life cycle. In the conventional Performance Test Analysis (PTA), field measurements and calculations are carried out on the basis of standard codes to find the whole engine performance parameters (i.e. power and efficiency) at test conditions and to compare them with the expected values. Recently, regarding the development of Gas Path Analysis (GPA) and diagnostic techniques to investigate the gas turbine health state, performance test capabilities can be improved by using these analyses to perform further examination on the measured test data and to determine the deviation of gas turbine component health parameters from the “new and clean” health state during the engine operation. Determining the mentioned deviations, potentials of engine improvement in the component level can be obtained and subsequently the action-oriented recommendations are reported as guidelines in the overhaul. Also in the case of performance test after the overhaul, the main result of the GPA application in PTA is the verification of the overhaul effectiveness. Using the GPA in the cases studied in this paper indicates that heath state of engine components can be investigated from the performance test data and as the main result, it is show that applying the GPA, it is possible to distinguish the effect of non-recoverable degradation and that of the poor overhaul on the engine performance and finally to assess technically the effectiveness of overhaul.

The sphere of the unknown, supernatural and miraculous is one of the most popular subjects for everyday discussions in Ayodhya – the last of the provinces of the Mughal Empire, which entered the British Raj in 1859, and in the distant past – the space of many legendary and mythological events. Mostly they concern encounters with inhabitants of the “other world” – spirits, ghosts, jinns as well as miraculous healings following magic rituals or meetings with the so-called saints of different religions (Hindu sadhus, Sufi dervishes),with incomprehensible and frightening natural phenomena. According to the author’s observations ideas of the unknown in Avadh are codified and structured in Avadh better than in other parts of India. Local people can clearly define if they witness a bhut or a jinn and whether the disease is caused by some witchcraft or other reasons. Perhaps that is due to the presence in the holy town of a persistent tradition of katha, the public presentation of plots from the Ramayana epic in both the narrative and poetic as well as performative forms. But are the events and phenomena in question a miracle for the Avadhvasis, residents of Ayodhya and its environs, or are they so commonplace that they do not surprise or fascinate? That exactly is the subject of the essay, written on the basis of materials collected by the author in Ayodhya during the period of 2010 – 2019. The author would like to express his appreciation to Mr. Alok Sharma (Faizabad) for his advice and cooperation.

In the last few years, it has often been said that the current fashion system is outdated, still operating by a twentieth-century model that celebrates the individualism of the 'star designer'. In I- D, Sarah Mower recently stated that for the last twenty years, fashion has been at a cocktail party and has completely lost any connection with the public and daily life. On the one hand, designers and big brands experience the enormous pressure to produce new collections at an ever higher pace, leaving less room for reflection, contemplation, and innovation. On the other hand, there is the continuous race to produce at even lower costs and implement more rapid life cycles, resulting in disastrous consequences for society and the environment.

To have a dis/ability opens the possibilities for seeing (understanding) something different because of difference in the disabled’s lens or worldview. Public administration is awash in self-doubt, discomfort and confusion. As it struggles with setting, moving and removing academic boundaries of the discipline, public administration reveals its own dyslexia. The disabling of public administration offers a view from the balcony (or orchestra pit) granting a greater appreciation of ‘the other’ in the public administration student, public administration theory and public administration practices. The dyslexic individual and institution can suffer and celebrate contradiction, paradox, irony, and other delimiting arenas of learning without resistance. Successful learning and understanding can come not in spite of but because of apparent disabilities.
