Abstract
Imperceptibility is one of the most important aspects of the steganography method. Specifically, for steganography in images, embedded messages must not be felt by the human visual system. Humans have a higher sensitivity in color images compared to grayscale images, therefore the method that is still being tested on grayscale images needs to be retested on color images. Previous research has shown that the bit flipping method can increase imperceptibility to around 9dB in grayscale images. In this research the bit flipping method is tested on color images in the RGB format, the message capacity embedded in the image is 1 bit per pixel. The results of the imperceptibility test turned out to result in a more varied increase due to the greater number of layers in the color image. However, the bit flipping method is also proven to work well on color images, and even a maximum PSNR increase of more than 13dB. At the extraction stage, the message image can also be extracted perfectly, namely with the value NC = 1.

Abstract
Four kinds of fruit waste in Blora and Tuban, Java Island, still have calorific values which could be harvested as a daily house hold energy source after they turn to charcoals. A small scale carbonization furnace needs to be designed to fulfil this purpose. This research aims at testing an impact of carbonization period to the yield of secang, roda, ketapang and siwalan (skin) fruit charcoals using PEM A-HRV furnace. The furnace was designed only for 4(four) kg in capacity to minimize emission during carbonization. The carbonization temperature was set at 400 ° C with the optimum carbonization period of 4(four) hours in the maximum furnace capacity. A natural draft inlet oxygen system was used for carbonization. The charcoal yielded was between 21.77 % to 32.57 % weight averaged from the 16 times tests. The Calorific values of charcoals vary from 5240 calorie/gram to 6490 calorie/gram (air dry basis) depending on the type of the fruit charcoal. The volatile matter content was still more than 20 % in weight (air dry basis) in the average, saying that the temperature for carbonization needs to be increased even though this may decrease the charcoal yield.

Authors: Sudarsono I , Aisyah L , Prakoso R N P 
Published: May 2020

Abstract
Pusjatan LWD is an equipment that is purposed to measure the structural strength of a pavement system especially unpaved roads. When the load of LWD falls, it generates vibration recorded by geophones. By using the principles of vibration theory then resulting deflection can be calculated. The deflection value is used for the calculation of modulus elasticity of soil using Boussinesq formula. The LWD is applied to Pusjatan’s yard in Bandung for sample of subgrade, where in each location we have taken ten data using LWD and DCP on the same tested points. The reason of comparing between LWD and DCP is that the former equipment used to measure the subgrade structural strength. The test results are a modulus elasticity then correlated with each other. The test results obtained the determination coefficient r2 = 0.7558, this means that the correlation value is 75.58% determined by the modulus of elasticity value of the DCP measurement, whereas on hard soil the correlation between modulus of elasticity of LWD with DCP Index, with the results r2 = 0.9684 or 96.84%. This indicates a strong correlation. This finding comes to the conclusion that Pusjatan’s LWD can be used to test structural strength of subgrade.

Abstract
Oil palm plantations produce waste that has not been used so far, namely Oil Palm Fronds. This waste can be converted into energy in the form of producer gas using gasification technology. This study aimed to model the gasification process using Aspen Plus in a multi-stage gasifier by adding air at the pyrolysis and oxidation zone. The influence of variations in air ratio (AR) between the pyrolysis and oxidation zones have been analyzed. The results of this model are validated with experimental data to get accurate results. Based on the modeling results H2 content for all variations of Air Ratio (AR) has increased from 8.12% in single-stage to 9% in multi-stage. However, when viewed from the total efficiency was lower than single-stage gasification. It can be concluded that multi-stage gasification can be applied to improve gasification performance, especially to increase volumetric percentage of hydrogen. However, when viewed from the total efficiency was lower than single-stage gasification. Overall, the results of gasification modeling using Aspen Plus can be used as a reference to improve gasification performance.

Abstract
Plastic waste has reached a critical stage because it harms life and ecosystems. Increasing numbers require treatment to reduce the widespread adverse effects. This research uses a literature study to describe various alternatives to plastic waste management. There are various steps in handling to manage plastic waste. Principle 3R (Reuse, Reduce, and Recycle) applied to handle the plastic waste. Recycle is an alternative today to handle the increasing amount of plastic waste, while reuse and reduce are expected to reduce the amount of plastic waste. Waste plastic can do on thermoplastic type plastics, which are plastic products/materials which can be melted again by heating to a specific temperature so that other products can forms as desired. Plastic products that can be recycled include PET (Polyethylene Terephthalate), HDPE (High-Density Polyethylene), LDPE (Low-Density Polyethylene), and PP (Polypropylene). Recycling for plastic waste done through a chemical process that is by thermal cracking/pyrolysis. Plastic that is processed by pyrolysis can convert plastic into fuel oil. With this method, two problems can be solved at once, namely the processing of plastic waste and the fulfillment of increasingly depleting energy needs.
