Abstract

Fly ash is a system of dry ash handling system burning coal by b oiler before getting to the chimney so as not to pollute the environment (air). Abu will pass the E lecture Static Recipient ( ESP ) and be temporarily accommodated at hopper . Then the ash will be transferred through the pneumatic AV pump system to fly ash silo . Fly ash transfer system failure occurred due to disruption of the pneumatic control system pump pa da AV system. This is because of the dome valve insert seal on AV pump leak and control system pneumatic fault because of contaminated by fly ash dust . The working intensity of the AV pump system in operation creates friction between the dome valve and dome valve insert seal which can cause erosion and leak on the dome valve insert seal . Frequent leakage at dome valve insert seal , has an impact on the spare part control system pneumatic contaminated by fly ash dust which causes damage to pneumatic spare parts and the cessation of the transfer process of ash to fly ash silos.The research was conducted with the addition of protection to the system pneumatic control AV pump by installing a quick exhaust valve on the system pneumatic AV pump in fly ash system , so that dust does not enter the AV pump's pneumatic control system when a dome valve insert seal leaks .

Abstract

The construction of simple houses is always done, to meet the needs of low and middle-income people. And every time you make a home, it requires a fee to buy materials, equipment and to pay workers. So estimating the cost and material requirements at an early stage is very important. But, there is no simple cost and material estimation method, at the conceptual stage, when there is very little data information, so this is a problem for non-professionals. The solution to the problem is a theory. The theory is a program which consists of models. So this study intends to create a program, as a conceptual estimate. The quantitative method in this study uses 36 data on the Budget Plan. The data is processed using the Burgerlijke Openbare Werken (BOW) method. Then the results of the data process were analyzed using the linear regression analysis method, to get the model. The models then form the formula for the program. So that in this study produce models and applications, to estimate the cost and material requirements for the construction of simple houses. Using the program, enter the building area data information, and automatically, the cost and material requirements for the development of a simple house will be predictable. This program is a simplification of the Burgerlijke Openbare Werken (BOW) method.

Abstract

The objective of this article is to review and represent about automation irrigations that have been gained in irrigation system performance evaluation for cultivation System of Rice Intensification (SRI) combined with Jajarlegowo System. This paper is based on the literature that is concerned with concepts, techniques, and methodologies applied to the automation irrigation and their performance in Indonesia. The development of automation irrigation for paddy field in Indonesia was presented and it was discussed. Several studies of automatic irrigation systems have been conducted in Indonesia. The results showed that the use of irrigation automation system combined with a system of rice intensification (SRI) and combined with jajarlegowo can increase rice productivity. This method is effective because the rice plants are watered according to their needs so that the growth becomes good. The method of irrigation automation is carried out using a water level control system adapted to the age of the rice plant. Water level sensors, irrigation actuators, and drainage actuators are installed in paddy fields to support the irrigation automation. In the application directly in the paddy fields owned by Indonesian farmers, this has not been done thoroughly. The main obstacle from the observation result of the research shows that automatic irrigation system technology has not shown any real difference compared to conventional irrigation. In addition, this automatic irrigation system should also be accompanied by human resources trained in its use and maintenance.

Abstract

The incompatibility of construction of urban or residential drainage channels with design criteria is often found due to difficulties in designing drainage channels. designers often make design mistakes when designing drainage channels. This study aims to evaluate the drainage system and designs a drainage channel that can collect runoff discharge on Residential Area. The results of flood discharge obtained using the Gumbel method for the 10 and 25 year return periods are 298.78 mm and 370.38 mm. From the calculation of the channel capacity in the field and the discharge plan most of the existing channel capacity cannot accommodate the current planned discharge of 2.261 m3s-1 for the primary channel and 1.824 m3s-1 for the secondary channel. The current channel cannot accept runoff discharge during rain, so the channel rehabilitation plan is carried out by expanding and extracting the dimensions of the drainage channel.

Abstract

The high percentage of drop-out students causes a campus management problem, this is because the percentage of students graduating on time is one of the elements of accreditation assessment set by the national accreditation board of higher education. One reason why the drop out rate is still high is because the Management System has not run well, such as lecturer professionalism, campus facilities, academics and administration, student affairs, outside influence and student personality. This study aims to analyze several indicators that can cause student drop outs by comparing the C4.5 method based on particle swarm optimization and Naïve Bayes based on PSO. This study contributes to campus management in anticipating the occurrence of drop outs through indicators that occur and can predict student drop out rates through the classification process. The highest level of accuracy produced from C4.5 + PSO is around 99.32% with AUC from Naïve Bayes is 0.974 categorized as excellent classification.

Abstract

Solar distillation has been used to distill seawater into clean water. The distillation process is largely determined by the effectiveness of the evaporation and condensation processes. This study aimed to investigate the method of condensing air into the water and evaporator space on the effectiveness of the evaporation process. The solar distillation is designed as two units with a single basin type. Type-I solar distillation is designed with the evaporator and condenser chambers in one room. The solar distillation type-II is designed with a modified evaporator chamber so that water vapor can be circulated out and without a condenser room. The solar distillation length and width are 600 mm and 400 mm, respectively, which are made of a 0.6 mm thickness stainless steel plate. At the top, it is covered by a 5 mm thickness glass with a slope of 10°. The test was carried out for 7 days together between the type-I solar distillation and the type-II solar distillation. Data on raw water temperature, room temperature, glass surface temperature, ambient temperature, and solar intensity were recorded during the test. The data is recorded every 30 minutes starting at 08.00 GMT+7 until 17.30 GMT+7. The test results show that the solar distillation performance is influenced by the high and low solar intensity. The volume production of water vapor in the type-II solar distillation is greater than that of the type-I solar distillation. This shows that condensing air into the water and evaporator space can increase the evaporation process's effectiveness on the solar distillation.

Abstract

The use of a dc micro-grid with the interconnection of the main ac power supply, which is provided from renewable energy sources such as the sun, wind, and other sources, was investigated in this article. Micro-grids will play a significant role in the future development of the energy sector, but the generation phase may differ. In this article, we show that when we use green energy sources for dc applications such as smartphone chargers, laptop chargers, and LEDs, the performance of the dc micro-grid device improves by up to 40%. This is due to the reduction of ac to dc and back to ac, which results in excessive power conversion losses in the current system. The PIC16F73 microcontroller is used to power the micro-grid device and solar tracker, increasing the model's performance. When this sort of device is attached to a specific load, it uses more power during off-grid renewable generation, resulting in more pulse width modulation (PWM) waveform generation, demonstrating the system's failure compared to renewable energy sources.

Abstract

In the machining phase, graphite in ceramic reinforced aluminum metal matrix composites improves machining efficiency. As a result of the forming of the tribological sheet, standard machining performance may increase. They need the most precise machining operations in the manufacturing fields, which result in the production of high-quality goods under ideal conditions. Composites' uses in engineering are increasingly expanding due to their unique properties, and these composites need the most detailed machining operations due to their manufacturing costs and applications. The fabrication of the hybrid particulate aluminum metal matrix composite (HPMC) in the sand casting method, as well as the findings of an experimental analysis on the Machinability properties of hybrid particulate aluminum metal matrix composite (HPMC), are presented in this article (Al-SiCp-Gr). The impact of strengthened silicon carbide and graphite particle ratios of 10 and 15 weight percentages was investigated. On the resulting surface roughness and material removal rate of workpieces, control factors of the turning process such as speed, feed rate, and depth of cut were investigated. Using the Taguchi, ANOVA, and S/N ratio techniques, the performance values were evaluated and optimized. It was discovered that increasing graphite strengthening and adding SCP to the mix improved the MRR while maintaining a strong surface finish. The pace and feed speeds of the cutting method are primarily responsible for surface roughness. The pace and DOC of the cutting operation have a significant impact on the MRR.
