Abstract

Vertical Clarifier Tank (VCT) has a very crucial role to separate oil, water and sludge by gravity, where oil with a smaller specific gravity of 0.8 grams / cm3 will be in the uppermost layer, while water whose specific gravity is 1 gram / cm3 will be in the middle layer, and sludge with a density of 1.3 grams / cm3 from the Vertical Clarifier Tank (VCT). The experimental design of this study was to determine the appropriate depth of the inlet pipe to obtain low levels of impurities during oil extraction. The results of the study obtained from variations in the depth of 25 cm, 40 cm, 55 cm, and 70 cm inlet pipes used as the inflow of crude oil from Crude Palm Oil with variations in sedimentation time of 100 minutes, 120 minutes, 140 minutes, 160 minutes, 180 minutes, and 200 minutes, obtained the least level of impurities in the Inlet Pipe which has a length of 55 cm with a variable sedimentation time of 200 minutes.

Abstract

This study aims to obtain information about the flow characteristics of Water-Air Flow, Mixture of Glycerin+Water(G20)-Air, and Mixture of Aquadest+Butanol 4%-Air. The two-phase flow characteristics in mini-sized pipes have significant differences with the two-phase flow characteristics in conventional pipes, so it will affect fluid distribution processes involving two-phase flow such as heat transfer processes. Therefore, it is necessary to conduct further studies on the two-phase flow pattern in mini-sized pipes. This research was conducted in a test section in the form of a glass pipe with a diameter of 1.6 mm in a horizontal position. The liquid fluid used is water which has a surface tension (σ) of 71 mN/m, a mixture of glycerin+water (G20) has a surface tension (σ) of 62.5 mN/m, and a mixture of distilled water+butanol 4% has a surface tension (σ) of 36.50 mN/m. Superficial velocity of gas (JG)=0.033–4.935 m/s, and superficial velocity of liquid (JL)=0.025–66.3 m/s. The results showed that stratified flow was not observed in the mini channel as can be found in conventional pipes. The detected flow patterns are: bubbly, slug, slug-annular, churn, and annular. The results of flow pattern maps compared with flow pattern maps from Triplett et al (1999a), Chung and Kawaji (2004) and Sudarja et al (2014), and Aqli et al (2015) show that the higher the viscosity, the higher the annular churn-slug flow transition line will be. decreases while the annular – slug annular transition line tends to be more sloping.

Abstract

This study aims to look at the performance of the solar water heater collector with the addition of a reflector. Reflector is used to increase the absorption of solar radiation. The test was carried out by varying the water flow rate in the pipe, namely 75 l/hour, 150 l/hour and 225 l/hour with a collector tilt angle of 30°. Tests are carried out every one hour, starting at 09.00-16.00 WIB for each variation. Parameters measured in this study included glass temperature, inlet water temperature, outlet water temperature, pipe temperature, absorber temperature, ambient temperature and wind speed. The results showed that the highest efficiency occurred at a flow rate of 225 l/hour, which was 62.44% at IT 3,366 MJ/m2, and the highest ratio of outlet water temperature and inlet water temperature was 1.51 at a flow rate of 75l/h. Adding a reflector to the coverslip can increase collector efficiency.

Abstract

The finned drive wheel technology is widely used for wet rice fields. Currently, finned drive wheels for peat fields have not been developed and still use traditional agricultural tools such as hoes and sickles, while the finned drive wheels for wet rice fields are not yet able to work optimally on peat rice fields. The driving wheel model and testing in peat rice fields were carried out in this research. Design and manufacturing were carried out by referring to previous research literature. This initial research was carried out in wet rice fields on open-close finned drive wheels and standard finned wheels, with the aim of measuring the comparative level of performance of the two wheel models. The wheel performance measured is sinkage and wheel rotational speed. The research produced two models of driving wheels, namely the standard fin type with a driving wheel diameter of 35 cm and a number of 8 fins and the open-close fin type producing a driving wheel diameter of 40 cm with 4 arcuate fins on the top surface of the driving wheel. Standard fin type drive wheels have smaller sinkage (11% on average) compared to open-close fin type wheels. The finned drive wheel with the open-close type has an average speed level that is 27.7% higher when compared to the standard finned type.Keywords – wheel drive, standard fins, open-close fins, sinkage, wheel speed

Abstract

Agricultural technology to support the agricultural sector, especially peaty paddy fields, should be developed, because peat land with a thickness of less than one meter has been recommended for rice crops. supported by a potential peatland area of ​​up to 21 million Ha or 10.8% of Indonesia's land area. Currently, peatland farming communities use sickles to harvest rice and hoes to cultivate the land. So far, hand tractor finned wheel drive technology has been widely used for cultivating wet paddy fields, whereas in conditions of peaty paddy fields it has not been able to be used because of the high level of sinkage and wheel slip, for this reason a new model of wheel is needed that is capable of working in peaty paddy fields. The aim of the research is firstly to find the right model of driving wheel for use in peaty paddy fields, secondly a prototype driving wheel for peaty paddy fields, and thirdly to experimentally test the driving wheel. Research results (1) prototype with a driving wheel diameter of 35 cm and the number of fins is 8 for the standard fin type and for the double fin type the driving wheel diameter is 40 cm with 4 vertical arc fins, which are placed on the surface of the driving wheel. (2) Comparison with the same type of loading shows that the double fin type drive wheel has a relatively smaller level of wheel loading (around 20%) when compared to the standard type drive wheel. (3) The sinkage level of the standard type drive wheel has a smaller sinkage (around 10%) compared to the double finned wheel type, in tests with the same type of loading. test loads for wheels are 20 kg, 40 kg and 60 kg. The double fin type drive wheel is good for use in peaty paddy fields.

Abstract

This study discusses the conceptual design process of an Unmanned Aerial Vehicle (UAV) featuring Long Endurance Low Altitude (LELA) characteristics, intended for long-range surveillance missions. The design is based on a quantitative approach through the estimation of initial performance parameters such as wing loading, power loading, maximum lift coefficient (CLmax), and lift-to-drag ratio (L/D). Technical data were obtained from literature and preliminary numerical calculations, then used to determine the main geometric dimensions and power requirements of the aircraft. The design results show that a UAV with a take-off weight of 15.08 kg, wing area of 0.2317 m², and cruise power of 67.34 Watts is capable of flying for 79 minutes with an L/D ratio of 13.69. The center of gravity (CG) is located 0.454 m from the aircraft nose, indicating good longitudinal stability. This research provides an essential early- stage contribution as a foundation for further development in the preliminary design phase.
