Abstract

Labuan bajo has several famous tourist such as: Komodo National Park, Lake Kelimutu, Batu Cermin, Kampung Bena, Seventeen Marine Park, Riung Island and Wae Rebo. With the increasing tourist sector in Labuan Bajo, more tourists come. With the increasing number of tourists, accommodation is also increasing and competing. The problem that becomes an issue here first is the existence of homestay residents who are less competitive with existing hotels and cottages. The second is the lack of character of traditional buildings displayed in homestay buildings, hotels, and cottages that already exist. So, this research aims to optimize homestays design to compete with other accommodation facilities. Based on the above problem issues, to solve the problem by analyzing, comparing, and evaluating the sample of tourist residences operating.  The design method used is the Cyclical design Process method in order to get optimal design alternatives. The final result obtained is in the form of a draft proposal that includes the arrangement of the floor plan and the proposal of the appearance of the design that has been adapted to the traditional building character and the needs of tourists.

Abstract

This photobioreactor research was carried out using Chlorella vulgaris algae as an O2-producing reactor and optimizing light energy as its energy source, with dimensions of 40x50x60 cm with control of pH, temperature, and chemical visibility factors. Variations are given by providing a supply of CO2 in both types of photobioreactors. Then it can be seen the concentration of O2 produced from the photobioreactor and its ability to overcome CO2 gas emissions. The use of glass as a reactor-making material is because glass is able to absorb visible light wavelengths in the range of 400–750 nm where at that wavelength microalgae can live and reproduce well. Before selecting the lamp used for the photobioreactor system. Measurements were carried out on two photobioreactors, namely, photobioreactors supplied and not supplied with CO2, and using three types of light sources, namely halogen lamps, LEDs, and sunlight. The maximum oxygen concentration value was produced by the photobioreactor supplied with CO2. The average percent error of the designed tool is 1.383% which is obtained by comparing the value of the designed tool with the reference measuring instrument.

Abstract

The purpose of this study was to utilize residues of the plastic waste pyrolysis process and LDPE plastic as a substitute of cement in the manufacture of paving blocks. The residual pyrolysis process used was a pyrolysis residue of a mixture of polypropylene (PP) and low density polyethylene (LDPE) plastic waste with mass ratio of 100% PP, 75: 25%, 50: 50%, 40: 60%, 25: 75, and 100% LDPE. The mass ratio of LDPE plastic and pyrolysis residue were 70:30%, 60:40%, and 50:50%. The comparison of sand and residual pyrolysis of plastic waste used was 1: 1. The block paving obtained was characterized using SEM and quality tests were carried out with parameters of compressive strength and water absorption. The results of SEM analysis indicate the existence of a bond between sand and plastic pyrolysis residues. The variations in the type of plastic ratio in pyrolysis process indicate the varying of compressive strength and water absorption of the paving blocks

Abstract

One of the control problems that is a challenge for an engineer and the chemical industry itself is chemical processes which are closely related to nonlinear processes. The linear method is the choice for many researchers to overcome problems in nonlinear processes, namely the linearization technique. This causes uncertainty whether the controller is able to work on the actual nonlinear process. The purpose of this study is to integrate Aspen Plus Dynamics and Matlab Simulink to eliminate linearization in order to be able to control nonlinear processes optimally. The method used is to perform steady state and continued dynamics simulation in the case study of the deisobutanizer distillation. Then integration of Aspen Plus Dynamics with Matlab Simulink using AMSimulink. The results show that steady-state and dynamics simulations have been successfully carried out. Aspen Plus Dynamics and Matlab Simulink are integrated and able to run together. The controllers used include reflux drum level control, top column pressure control, and reboiler level control. The response results obtained in the co-simulation run well, the process response can perform setpoint tracking.
