Abstract

In this paper, to strengthen the connection between wood joints is conducted by the use of combination of bolt and epoxy adhesives. There where three variations of connection observed in this study e.g; U1, U2, U3. U1 was using a bolt connecting device. U2 was using a bolt connectors which is reinforced with epoxy adhesive on the bolt hole. U3 was using a bolt connectors which is reinforced with 40 MDGL epoxy adhesives in the joint slice plane. The result of this study indicates that the bolt connection yielding mode is theoretically as same as the yielding mode that occurs in the result of laboratory testing, named mode IIIs. The lateral resistance of bolt joints form laboratory tests result is 108% greater compared to the lateral resistance of bolt joints theoretically. The addition of epoxy adhesive to the bolt hole does not provide the real reinforcement of the joint extension of Ulin Woods with bolt connecting tools. The addition of epoxy adhesives with the amount of 40 MDGL in the joint slice plane, provides 16.6% reinforcement on the joint extension of Ulin Woods with bolt joint tools.Keywords: reinforcement joints, bolt joints, epoxy adhesive joints, lateral resistance

Abstract

Asphalt concrete wearing course (AC-WC) is the top layer in flexible pavement. Asphalt concrete is a mixture of asphalt, coarse aggregate, fine aggregate and filler. Many types of filler have been used to improve asphalt concrete performance. In this research, a combined of brick ash and rice husk ash was used as filler. As wasted products, this mixed filler can be used as an alternative replacement of Portland cement due to their similar chemical compounds. The objective of this research is to analyze Marshall characteristics (stability, flow, volumetric properties and Marshall Quotient) of an ACWC mixture containing a combination of Portland cement and a mixed of 40% brick ash and 60% rice husk ash as filler. Ratios of cement and the mixed ash used were 100:0, 50:50, and 0:100. After obtaining the optimum asphalt content for each different filler variation, Marshall test were performed to obtain flow, stability and density values. The result of tests showed that the composition of filler 50:50 gives Marshall characteristics with stability value of 1250,5 kg and air void of 4,846%. The composition of filler 0:100 gives Marshall characteristics with the highest stability value of 1692,9 kg and the smallest air void of 4,533%, which satisfied the specifications of Bina Marga 2010 Revision 3. Keywords: rice husk ash, brick ash, AC-WC, filler

Abstract

Wi-Fi (Wireless Fidelity) is an application of WLAN (Wireless Local Area Network) using IEEE 802.11 standard. Wi-Ficommunication systems use radio networks with a frequency of 2,4 GHz, a weakness in wireless communication issusceptible to interference called co-channel and adjacent channel. In this research solution given by two methodscalled geographical separation and guard band. Geographical separation is a method that is done by giving thedistance between two interconnecting devices. Separation based on the scope of the coverage area of the device that isby gradually shifting until no interference occurs again. Guard band method is a method by giving the space band onboth interconnected channels of 3 MHz. In this study the parameter in the analysis is the SNR (Signal to Noise Ratio)value, the lowest SNR value occurs in the geographical separation method at a distance of 10 meters on signal channel1 with signal channel noise 1 is 12 dB when interference co-channel. The highest SNR value occurs in testinggeographic separation method in channel 7 with signal channel noise 4 at a distance of 40 meters when adjacentchannel interference occurs is 56 dB. Research result shows the most effective method to reduce the impact ofinterference is the geographical separation method.Keywords: Geographical separation, guard band, interference, Wi-Fi.

Abstract

Road is one of transportation infrastructure which has very important role in economic growth in rural or urban areas. SM Amin Road is located in Payung Sekaki District and this road is an arterial road that has 2 track and 6 lanes. SM Amin road has length of 8.14 km and widthof 8 m. The road was previously overlayed in 2016 because the road was damaged such as swelling, potholes, and cracks. At present (2019) the road is damaged again so that it could be dangerous for road users. This study analyzed deflectometry result from benkelman beam. Theresults reveal that the subgrade is in poor condition. The condition was analyzed using 2017 Bina Marga Method, it shows that overlay is required along STA 03+900 until 05+200 with the thickness of 11 cm. The results of the deflectometry analysis shows that Jalan SM Amin hasa poor subgrade, so it is necessary to be improved. However, handling using structural overlays according to the 2017 Bina Marga Method can be used to reduce the stress which received bythe subgrade so that it can minimize the cost of pavement repair.Keywords: 2017 Bina Marga Method, Benkelman Beam, Deflection, Deflectometry, Overlay

Abstract

Restaurant waste is biomass which has the potential to be developed into renewable energy in the form of biogas. The choice of restaurant waste is the main substrate for biogas production because the waste contains many elements of organic material which have not been widely used, especially for biogas production. Besides of restaurant waste, tofu liquid waste and cow dung are very potential to be used as additional substrates in the biogas formation process. This research aims to study the effect of variations in the composition of organic waste (restaurant waste, tofu wastewater and cow dung) on the quality of methane gas in biogas production. The research was conducted using an 30-liter anaerobic biodigester with a working volume of 22.5 liters. The research variables are substrate variations, namely 100% restaurant waste, 50% restaurant waste : 50% tofu liquid waste, and 93.75% restaurant waste : 6.25% cow dungThe results showed that the initial pH value of the three biodigesters ranged from 6.63 to 6.7 where the pH range was still within the ideal pH value in making biogas, which ranged from 6.6 to 7.6. While the temperature of each reactor in this study has fluctuated, ie 28 ° C - 29.7 ° C, in this temperature range biogas can still be developed.

Abstract

Monoglyceride (MG) is a compound containing one ester group (-COOR) with a long chain of fatty acids and two hydroxyl groups (-OH). MG is the most widely used compound as an emulsifier in the food industry. Emulsifier is a compound that has surface activity so that it can reduce surface tension and stabilize the emulsion. MG has the ability to reduce surface tension and can stabilize oil and water emulsions. MG can be synthesized through esterification of fatty acids with glycerol using an acid catalyst. Esterification reaction is an endothermal reaction that is reversible and the reaction conditions effect the conversion of the reaction obtained. The operating conditions in the esterification of fatty acids with glycerol effect the reaction conversion as well as the quality of the monoglycerides produced. MG production through esterification of fatty acids with reaction conversion and high purity has been found in the use of DES (deep eutectic solvent) as a catalyst. DES is stable and not volatile so that it can be used repeatedly (reused) without reducing its catalytic activity in the esterification of fatty acids for monoglyceride production. Keywords: DES, emulsifier, esterification, fatty acids, monoglyceride
