Abstract

A lot of fresh food are easily damaged so they use chemical preservatives. Liquid smoke is a natural preservative because it is safe for health and the environment. The raw material used by agricultural waste, namely coconut shell. Liquid smoke that is quality and safe to consume must go through a purification process to eliminating the content of benzo(A)pyrene compounds because it is a carcinogenic compound that is very dangerous for human health if consumed. The purpose of this study was to determine the quality of liquid smoke through a purification process using active zeolite filtration to optimize the performance of pyrolysis reactors to producing liquid smoke. This research was carried out by pyrolysis, distillation and filtration at optimum operating conditions then analyzed using GC/MS and LC/MS. The results of this study are the amount of yield of liquid smoke from coconut shells without drying and drying is 36% and 28.8%. The remaining charcoal from coconut shells is 33% and 50%. The number of components lost from coconut shells was 31% and 21.2%. The performance of liquid smoke equipment from coconut shell is 4.37 g / (jam.m) and 5.59 g / (jam.m). The quality of liquid smoke produced for phenol from coconut shell is 3.04%. The quality of acidity is 7.3%. The pH value is 2.31. Liquid grade 1 smoke from coconut shell was not detected of benzo (A) pyrene after passing the zeolite filtration process. The values ??of phenol content, acidity, pH value and undetectable benzo(A)pyrene compound on liquid smoke are indicate that zeolite filtration is very optimal and produces liquid smoke with good quality.

Abstract

Indonesia has more than 80 thousand villages as the smallest administrative unit of the Republic of Indonesia. Each village needs at least three to four bridges to cross the river, and to access other facilities. The many bridge needs are not accompanied by the state budget allocated to the construction of bridges in villages. One alternative bridge construction is from wood material is also a renewable material. Constraints in the use of wood for building construction are the scarcity of wood with large dimensions. To overcome this problem, there is engineering wood (engineering wood), one of which is the box beam. Box beams are proven to increase the inertia of a material when compared to conventional wooden beams with the same cross-sectional area. This study aims to find a comparison of the strengths between conventional wooden bridges and wooden bridges using Camper box beam elements. The results of this study indicate that from the comparison of box beams and ordinary wood beams it turns out that the box beam produces a voltage of 0.129 MPa and a conventional beam of 0.142 MPa. Based on the results of the study it can be concluded that the box beam has a higher compressive strength than solid wood with the same cross-sectional area. And can be a recommendation for the selection of short span bridge structures for Rural because it is more economical and strong.

Abstract

Intersection is one part of the road that is the area where traffic conflicts occur. The existence of this conflict will result in interference with the movement of the vehicle. This situation is generally known as traffic flow congestion. Geometric condition of unmarked intersection on Mertojoyo - Joyo Utomo roads of Merjosari village Malang city, conflicts often occur which are caused by the approaching width which is less proportional to the current of the vehicle, so it is necessary to analyze. The purpose of this study is to determine the size of the intersection capacity, intersection performance and alternative intersection improvement directions. The method used in analyzing this perverse performance refers to the Indonesian highway Capacity Manual 1997 (MKJI 1997). To analyze this crossing, the average traffic data collected during 12 working days is taken. Based on the recapitulation of traffic volume for 12 working days, the highest QTotal was 2994 smp/hour which occurred on Saturday period 17.00 - 18.00. Based on the results of data analysis of traffic flow on a busy Saturday, the period 17.15-18.15, obtained QTotal = 2994 Smp / Hour, capacity value (C) = 2135.98 smp/hour the degree of saturation (DS) = 1.381 > 0.75 values suggested MKJI 1997. Alternative installation of prohibited traffic signs turn right on the main road, C = 2693,829 smp/hour, degree of saturation (DS) = 1,112 > 0,75. Alternative widening on main roads and minor roads and the installation of prohibited traffic signs turn right on the main road, obtained C = 3178,378 smp/hour, DS = 0,94 > 0,75. Alternative two-phase signaling and widening on the main road and minor road, the capacity of each approach < 0.75 is obtained, thus overcoming the problem at this intersection.
