Abstract

This research objective is to improve the quality of Crude Palm Oil (CPO). In general, CPO contain free fatty acid known as FFA. CPO purification is necessary to eliminate FFA. In this research, CPO purification conducted by using adsorption method with various adsorbent. The adsorbent has to be activated with NaOH 0,087 N before being used. The variable used are variation of adsorbent (zeolite, bioceramics, and carbon active), adsorbent size (mesh of 20,30, 40,80, 100), and mixing time (10, 20, 30, 40, and 50 minutes). CPO quality can be analyzed by acidic-alkaline method to measure the number of acid, proxyde, saponification, iodine, and water value. The result showed that the optimum condition occurred when using zeolite of 100 mesh and 50 minutes mixing time. Before adsorption, the measurement for number of acid, peroxide, saponification, iodine and water value are respectively 1,9889; 16; 150,0675; 19,6695; and 6,572%. While the measurement result after adsorption are 0,1989 for acid number; 2 for peroxide number; 200,5575 for saponification number; 45,684 for iodine number; and 0,242% for water value. Compare to SNI 01-3741-1995 Standar Mutu Minyak Goreng, the result showed that CPO quality is improved and in line with the SNI requirement.

Abstract

At the building, for example the office building, hotels or the apartment, is needed by a controlsystem of the temperature. This is caused the number of rooms so it is difficult to monitor the use ofAir Conditioning (AC) for each room. This control system is used to monitor the temperature ofeach room so as to be able to control the use of AC. This paper will discuss the designing of controltemperature by using technology of Wireless Sensor Network (WSN). WSN technology made use ofthe Zigbee wireless network as the data communication, where each room was installed by atemperature sensor (the node sensor). The node sensor that is installed in each room are connectedwith each other and make the star, the tree or mesh network formation. The advantages of thissystem is using Zigbee wireless that is free of the licence. The results of the temperaturemonitoring of each node sensor are afterwards gathered in the Base Stasion Controller (BSC) thatbecame the centre of managing and processing the data, so as to be formed a control system of thetemperature of each room to this building.

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

Ground Penetrating Radar (GPR) survey using 200 MHz frequency antenna have been conducted in July 2011 at Kedaton Temple Complex, Muarojambi, Jambi, Indonesia. The survey is aimed at providing subsurface information without digging (excavation) as in usual  conventional archaeological methods. The data were collected on six lines around the main building and a courtyard inside the boundary fence of Kedaton Temple Complex. Good quality data were obtained with signal to noise ratio greater than 110 dB. The result of the subsurface model based on the electromagnetic properties of rocks generating three layers of soil, from the youngest are Layer A with a thickness of 0.26 meters to 0.78 meters, Layer B with a thickness up to 1.51 meters, and Layer C coveringthe indication of archaeological object with a thickness of 0.35 meters up to 3.87 meters. The southern part of the main building showsa delineation and spread of thick layers of soil with a total thickness up to 4.50 meters, while the northern part of ancillary buildings shows a delineation and thin layers of soil with a total thickness only 2.60 meters. The indication of archaeological objects in the sub-surface indicated by the presence of anomalous heights which has a depth varying from 1.65 meters to 4.50 meters. This is interpreted to be a sub-surface anomaly that is likely to be archaeological objects still buried. The archaeological object may represent an ancient building in the zone of depression that accumulates due to the great floods, tidal Batanghari River, and sea level fluctuation in the past.Keywords: Archaeology, geophysics, Ground Penetrating Radar (GPR), Kedaton, Muarojambi.
