Abstract

Metal plating frequently employs nickel (Ni) and copper (Cu) as anodes. Cu/ Cu-Ni film formed has many advantages, such as better corrosion resistance and high hardness characteristics. This study aims to assess the properties of Cu/Cu-Ni film, such as phase, surface morphology, crystallographic orientation, hardness, corrosion analysis, and contact angle, which were fabricated using electrodeposition with various Ni salt additions (0.3, 0.5 and 0.7 M). In addition, the cathode current efficiency (CCE) and deposition rate of the Cu/Cu-Ni electrodeposition were also investigated. An increase in Ni salt in the plating bath could enhance the pH, promoting higher CCE and depleting hydrogen evolution at the cathode, leading to the presenting Ni phase in the alloy. The higher concentration of Ni salt in the solution could also enhance the deposition rate due to a shift to a pH value, which affects the roughening of the surface morphology, promoting a higher contact angle. All crystal structures generated by Cu/Cu-Ni electrodeposition were FCC, with the preferred orientation of the (111) plane. Crystallite size and lattice strain depend on the deposition rate. Less crystallite size and lattice strain affect the film’s hardness and corrosion resistance. Moreover, the third bath had the resulting Cu-Ni layer with the best hardness and corrosion rate of around 136 HV and 0.081 mmpy.

Abstract

In the construction of residential buildings such as simple houses, the existence of a door is certainly a basic requirement that must exist. One of the criteria of a good door is weather resistance by having a good door leaf material, not easily weathered and also not easy to shrink (expand or bend). Generally, doors are made using wood materials because they add aesthetic value to the building construction with a variety of grain patterns and unique textures from wood. But on the other hand, the forest current condition as a source of wood production is increasingly concerning. This also has an impact on good quality wood which is difficult to obtain and increasingly expensive. Technological developments in the field of construction materials provide an alternative from the usage of door leaf materials which majority using wood materials to switch to alternative materials usage such as steel, glass, PVC and lightweight concrete. The usage of lightweight concrete began to be widely used as a door leaf material because it is more resistant to weather, has a stable size and is not weathered by termites. From an economical standpoint, the price of lightweight concrete doors is relatively cheaper compared to the price of wooden doors with equivalent specifications. The purpose of this Community Service activity is to increase public understanding, to provide knowledge about alternative wooden door as well as providing examples of alternative materials, namely lightweight concrete doors with wood texture and environmental friendliness. The used method consists of several stages, namely socialization of the development of the construction material technology, installing lightweight concrete panel doors in the Bendung Serang sub-district and showing the installation process and making of lightweight concrete panel doors through videos and photos showcase. The benefits specifically for the people in the Bendung  sub-district is that the innovation of this lightweight concrete panel door material is acceptable.  This community service activity has educated the public about technological innovations in construction material such as alternative materials.

Abstract

Fried food waste can have negative impacts on environmental and health problems. On the other hand, fried food waste can be processed into biodiesel and animal feed. So that the utilization of fried food waste can increase the supply of fuel and animal feed which continues to increase along with the increasing population in Indonesia. Cooking oil is a renewable material because it comes from palm oil, coconut, corn, soybeans and others. So that the manufacture of biodiesel and animal feed can be preserved and developed in the future. Based on these problems, community service activities (PkM) in RT 3 and RT 5 located in RW 13, Curug Village, Bogor. This PkM activity was attended by 20 participants and was carried out in five stages. The first and second stages were in the form of counseling containing the delivery of material on making biodiesel and animal feed. In the third and fourth stages, training was given on making biodiesel and animal feed. While in the fifth stage, monitoring and evaluation were carried out. The indicators of the success of this activity were evaluated based on the pre-test and post-test values ​​carried out for both biodiesel making activities and animal feed making activities. Based on the evaluation of the comparison of pre-test and post-test assessments carried out by participants, it shows an increase in understanding of biodiesel production from an average value of 38 to 75 or an average increase of 99%. While the increase in understanding of animal feed production from an average value of 21 to 69 or an average increase of 224%. This activity received high attention from the local community.

Abstract

Cikarawang Village, Dramaga, Bogor is a village with a large potential for water resources. However, the water in this village has high levels of Mg2+ and Mn2+. High levels of Mg2+ and Mn2+ can cause eye and nose irritation, as well as influenza symptoms. To reduce the levels of Mg2+ and Mn2+ in water, this study used the adsorption method using activated carbon and bentonite. The results of the study showed that the levels of Mg2+ and Mn2+ in water can be significantly reduced using the adsorption method. In sample 1, the level of Mg2+ decreased from 14.64% to 11.64% after adsorption for 30 minutes. In sample 2, the level of Mg2+ dropped to 0% after adsorption for 30 minutes. In sample 3, the level of Mg2+ decreased from 9.60% to 5.76% after adsorption for 30 minutes. In general, the longer the contact time between the sample and the adsorbent, the greater the decrease in the levels of Mg2+ and Mn2+. However, for sample 2, the level of Mg2+ dropped to 0% after adsorption for 30 minutes. This indicates that sample 2 has a very high level of Mg2+ that can be adsorbed perfectly by bentonite in a short time. This study concluded that the adsorption method using activated carbon and bentonite is an effective method for reducing the levels of Mg2+ and Mn2+ in water.

Abstract

This study aims to examine the decomposition method of liquid waste in the home industry, especially in the tofu industry, by using non-thermal plasma and electrocoagulant methods that are environmentally friendly and with low energy. In this study, the plasma method, electro-coagulant method, and a combination of both (electro-coagulant followed by plasma method and plasma followed by electro-coagulant method) were used to decompose liquid waste in the tofu industry. The results showed that non-thermal plasma followed by the electrocoagulation method was the most effective in reducing the T.D.S. value of 1983 ppm (the minimum value of the total control T.D.S. was around 2702 ppm), the minimum value of electrical conductivity (E.C.) was around 3967 (μs/cm), and also obtained a value of 3967 (μs/cm). pH 7.0. Based on the research results, non-thermal plasma combined with the electrocoagulant method can be applied to more optimally decompose liquid waste, especially in the tofu industry. The combination method of plasma and electrocoagulation to decompose the tofu industrial wastewater, which is environmentally friendly, is the novelty of this research
