Abstract

he purpose of this study is to design a bio-briquetting machine with screw extruder type to convert biomass into higher density based on quality standard of charcoal briquette SNI 01-6235-2000 and SNI 19-4791-1998. The machine had production capacity of 30 kg/hour, equipped with the motor of 1 HP which transmitted to the machine through pulley and belt, and also has cutter which rotates continuously. The raw materials of the bio-briquette were using bagasse and coconut shells. There are 6 parameters that are used to test the quality of bio-briquette such as calorific value, inherent moisture, ash content, dependability pressure, volatile matter content, and fixed carbon content. The bio-briquette was made from the raw materials using amylum adhesives with ratio 30:70:30. With feed as 5 kg, the machine produced 50 pieces of bio-briquette. The machine could produce good bio-briquettes such as calorific value of 6,511.3 cal/g, inherent moisture of 1.97%, ash content of 5.88%, volatile matter of 27.71%, fixed carbon content of 64.99% and compressive strength was 16.98 kg/cm2.

Abstract

Pokdakan Karya Mandiri Jaya is a group of fish farmers located in Marta Jaya Village, Ogan Komering Ulu Regency, South Sumatra Province. The main problem faced by Pokdakan Karya Mandiri Jaya is the relatively low survival rate of snakehead fish. This group is only able to produce 5000 snakehead fish larvae at a time spawning with the survival rate of the snakehead fish becoming adult snakehead fish around 70-75%. This is due to a decrease in water quality caused by the accumulation of leftover feed which is not handled regularly. Therefore, a system is needed to monitor pH, temperature and turbidity of water so that cultivators can take initial preventive measures. Service activities are carried out in three stages, the first stage was analytical situation, the second is planning and the last is implementation. The IoT device that was previously installed has already carried out the calibration process. The calibration results showed that the IoT tool can be used in the Pokdakan Karya Mandiri Jaya snakehead fish cultivation. It is hoped that from the application of IoT technology, Pokdakan Karya Mandiri Jaya can reduce the risk of death of snakehead fish and increase snakehead fish production.

Abstract

This study aims to examine and analyze: The effect of destination quality on tourist engagement, the effect of destination quality on tourist loyalty, the effect of tourist engagement on tourist loyalty and the effect of destination quality on tourist loyalty mediated with tourist engagement. The data analysis method uses a structural equation model. The research sample is tourists who have visited natural tourist destinations in South Sumatra totaling 320 respondents.  The results of this study prove that the destination quality affects tourist engagement.  Destination quality affects tourist loyalty.  Tourist engagement affect tourist loyalty.  Tourist engagement mediates the effect of destination quality on tourist loyalty. The implication of this finding explains that tourist engagement driven by destination quality will be able to increase tourist loyalty.

Abstract

DLP (Digital Light Process) 3D Printer Technology is a 3 dimensional printing machine made from resin with a lighting system using a light projector with a layer-by-layer printing process. In this research, the writer will make an object, which is one of the machining components, namely the gearbox casing. In this study the authors will analyze the effect of process parameters (exposure time, off time, and their interaction) on the dimensions of the printout and get the most optimal parameters to be applied to components or printing objects. In conducting testing, the measurement of the tester’s dimensions uses the Krisbow KW06-422 calipers. Then the measurement data is processed by the Anova method with the help of software design expert version 10. After the research process obtained the results that the most influential parameters are the interaction factor between exposure time parameters and off time parameters on the dimensions of the printed objects, and the most optimal combination of parameters is found in the exposure time parameters 10 second and off time 1 second with a level of precision of 95%.
