PENGARUH DIAMETER MUFFLER TERHADAP EMISI KARBON MONOKSIDA (CO) PADA MOTOR BENSIN
Get PDFABSTRACTThis study aims to determine the effect of muffler design on emissions emitted by gasoline engine smoke and make efforts to reduce it by modifying mufflers. Exhaust gas emissions on gasoline-fueled engines contain pollutants such as carbon monoxide (Co) gas. The scheme that is implemented in reducing gas Co, is by comparing the results of the emission test with 3 muffler diameter variables. The research method used is descriptive analysis of experimental testing directly on samples with a standard diameter (22 mm) muffler and two mufflers that have been modified with modified the diameter is 18 mm and 27 mm. Data analysis using Microsoft Office Excel software in the form of tables and statistical analysis The results showed that the oxidation catalyzing process with the addition of air treatment on modified mild steel / MS material mufflers Ø 10 mm can reduce HC pollutants by 37.74%, CO by 23.18%, temperature rise of 28.92%, MS Ø 15 mm HC of 31.45% and CO of 27.47%, increase in temperature of 31.33%. Stainless steel / SS Ø 10 mm HC of 32.35%, CO of 28.76%, temperature rise of 10, 84%, SS Ø 15 mm HC of 37.74%, CO of 42.92%, and temperature increase of 14.46%

ERANCANGAN AS RODA TROLI PEMANJAT TANGGA BERDASARKAN ANALISIS TEGANGAN DAN FAKTOR KEAMANAN
Get PDFManual material handling using hand truck is limited to flat surfaces. Hand truck equipped with tri-star wheel mechanisms can overcome these problems. On this research is discussed about the design of the tri-star wheel mechanism on the stair-climbing hand truck. For the first step, Design aims to analyze stresses and factor of safety on the shaft that supports the frame and wheels. The shaft is designed through the selection of material and dimensions to determine the factor of safety according to the amount of loading given. The modeling results in the software are then analyzed using the FEA simulation method. The shaft component uses various material ASTM A41, AISI 304, and AL 6061 with diameters of 6 mm, 12 mm, and 18 mm. The shaft receives a load of 400 N. The simulation results show that the materials that can be used are ASTM A41 and AISI 304 with a diameter of 12 mm and 18 mm, while the AL 6061 material can only be used on a diameter of 18 mm

Perancangan dan Analisa Implementasi LTE Home pada Jaringan 4G LTE di Frekuensi 2300 Mhz
Get PDFDesign and analysis of lte home implementation on 4g lte networks in 2300mhz frequency. The demand for data connections for customers is currently increasing. FTTx as one of the Fix broadband technology (FBB) has several weaknesses, especially when applied to rural areas. LTE Home as a smart home technology is a form of WTTx 4G LTE technology service that is expected to be able to meet the data needs of customers. This study aims to design and analyze the implementation of LTE home by measuring the value of QoS Class Identifier (QCI) and the value of Radio Frequency Key Performance Indicator (RF KPI) to improve network reliability for voice and data communication services. Some parameters measured are packet loss, delay, jitter, throughput for QCI values and Radio Signal Received Power (RSRP) and Radio Signal Received Quality (RSRQ) for RF KPI values.The results of RF KPI Measurement show that the value for RSRP is -89dBm. This value is quite good because it matches the predetermined KPI standard, which is between -70 to -90 dBm. For RSRQ values obtained for -11dBM, this result is classified as good according to the KPI standard which is <-8 dBm. These results indicate that the quality of 4GLTE network services provided for LTE Home implementation services has met RF KPI standard values. Whereas for the QCI parameters obtained results that both voice call and video streaming, the value still meets the standard Good for the User Experience KPI (QCI) value that is packet loss <5%, delay <150 ms and jitter <75 msKeywords: LTE home, RF KPI.

PEMISAHAN SUARA TERCAMPUR BERDASARKAN KARAKTERISTIK BINAURAL
Get PDFDalam suatu percakapan di pesta cocktail, seseorang mampu memfokuskan pendengarannya pada seorang lawan bicaranya meskipun bunyi musik latar cukup keras dan disertai percakapan beberapa orang lainnya. Fenomena ini dikenal dengan the cocktail party effect. Dalam sebuah studi awal dijelaskan bahwa binaural hearing memberikan kontribusi penting dalam efek tersebut. Penelitian tentang pemisahan suara yang berdasarkan pada lokalisasi bunyi telah dilakukan sebelumnya. Pada penelitian tersebut, pemisahan suara tercampur hanya berdasarkan binaural cue - interaural time difference. Maka pada penelitian ini, akan dilakukan pemisahan suara dari input binaural dengan 2 sensor mikrofon dari dua sumber suara berdasarkan kedua binaural cue tersebut yaitu interaural time difference (ITD) dan interaural level difference (ILD) menggunakan binary mask. Untuk mengestimasi nilai ITD, digunakan metode cross-correlation yang nilai ITD direpresentasikan sebagai nilai time delay pada pergeseran peak pada unit time-frequency. Binary mask diestimasi berdasarkan pola perubahan nilai interaural time difference dan interaural level difference terhadap nilai relative strength dari sinyal target yang dihitung secara statistik menggunakan probability density estimation. Hasil pemisahan sumber suara tercampur menunjukkan performa yang baik dengan SNR sebesar 3 dB
