Published: December 2021

Abstract
The smart city concept has been implemented in countries worldwide as the solution for various urban problems. In Indonesia, the smart city movement was initiated in 2017 to create 100 smart cities. Previous studies identify challenges to the implementation and that smart people or smart citizens are essential dimensions of a smart city. This study aims to gain insights into the smart city implementation and citizen engagement in Indonesia through the online social network by conducting a focus group discussion (FGD) with four academicians and in-depth interviews (IDIs) with six representatives of the related government institutions. FGD and IDIs indicate that the implementation of smart cities should be adjusted according to the local situation. The critical success factors of the implementation are namely, local wisdom, transformational leadership, sustainability, and political content. The results also reveal that, in general, the city residents have been involved in implementing of the smart city through the online social network. However, a kind of incentive system is still required to ensure that the city residents are encouraged to solve the city problems.

Published: December 2021

Abstract
Community empowerment is one of the effective strategies in conservation efforts. However, empowerment-based conservation still leaves some problems to be solved. The most significant issues in empowerment-based conservation are sustainability and human resource issues. This study sees the problem can be solved by integrating religious aspects in empowerment-based conservation efforts. Through its teaching about the environment, religion can instill values and shape the behavior of people and people who care about the environment. For demonstrating this possibility, this study reviews the literature available in discussions on the role of religion in environmental conservation, community empowerment, and conservation efforts. From the existing literature, religion instills values, shapes behavior, and ensures its sustainability. This is possible through features in religion, such as the message of responsibility in the concept of divinity, karma and reward/sin, or other features such as the ability of institutions to spread values that are intertwined with the emotional, cognitive, and even political aspects of society.

Published: December 2021

Abstract
The study aims to analyze the factors affecting community involvement in the waste separation and reduction through waste bank for low participation through benefits offered to its member. Logistic regression was used for the analysis, and there were 26 dependents variables applied to the analysis. The result showed that six variables, i.e., age, occupation, participation in social activities, knowledge of sustainable development, distance from HH to WB, and availability of dissemination of 3R, affect people’s motivation to be member and actively involved in waste reduction through the waste bank. All variables except distance are proportional to the motivation of the community to participate in waste bank. The attained model is used to calculate the probability of community participation in waste banks afterward. Using different conditions, where variables are set with values of zero and one representing absence and availability of related variables, respectively various probability values come out ranging from 0% to 94.8% which is the highest probability value if all significant factors are available.

Published: December 2021

Abstract
Biofuel production as an alternative energy source has been promoted and spread worldwide, but there is actual potential. Malapari (Pongamia pinnata) is a forestry-based biofuel. This paper aims to determine community perception and attitude towards malapari as a biofuel. The research was conducted in August - October 2018 in Patutrejo Village, Grabag District, Purworejo Regency, Central Java. This research was conducted using a survey method. Determination of respondents used a purposive sampling method. Respondents consisted of 38 people. The result showed respondents had poor to feeble perceptions and attitudes towards malapari. It is presumably because public knowledge of the use of malapari as a biofuel is low due to lack of socialization from related parties. There is no evidence of the utilization/processing of malapari seeds as a biofuel.

Abstract
Building construction will increase along with the increase in population in urban areas. For maintaining the carrying capacity of the environment to remain in balance, it is necessary to have a control instrument in the development of urban areas, one of which is through a Building Permit (IMB). To increase the effectiveness of the policy for implementing the IMB, it is essential to know the public’s perception of the IMB and experts regarding their views. Through interviews, questionnaires, spatial analysis, and AHP, this research is expected to be a material consideration for stakeholders in deciding policies for implementing IMB in South Jakarta. Spatial analysis was used to compare land cover, questionnaires were used to see people’s perceptions of building permits as an instrument for controlling and protecting urban areas, and AHP was used to validate the expert team’s opinion regarding IMB. The increase in green land in South Jakarta, the perception of public awareness in South Jakarta regarding the obligation to build a IMB and its impact on the environment is still high, and the accountability factor of the implementing licensing organization is one of the factors that can increase the effectiveness of the application of a building permit (IMB) in South Jakarta.

Abstract
The rate of world population growth gets faster every year, while on the other hand the land available for food production activities is increasingly limited. Efforts to increase income and food crop production by using cocoa farming to support national food security can be done by optimizing of land through crop diversification patterns by planting local tubers under cocoa farming. This research aims to analyze the optimization of land use, revenue and production costs. In addition, analyzing the nutritional content contained in each type of local tubers, namely sweet potato, cassava and taro. The research was conducted in the the buffer zone of Lore Lindu National Park (TNLL), Palolo District, Sigi Regency, Central Sulawesi Province, Indonesia. The results showed that the optimization of land use and revenue was obtained through the diversification pattern of sweet potato and cocoa. Optimization of the costs use occurs in the use of fertilizer production inputs. In addition, sweet potatoes have a higher calorific value, protein and fat compared to cassava and taro. However, the carbohydrate content of cassava is higher than that of sweet potato and taro.

Abstract
This study aimed to screen the activity of methanol extract of sponge-derived actinomycetes as an anti-biofilm and antibacterial agent to Staphylococcus aureus. Nine actinomycetes isolates were selected from the UPT LTSIT deposit. S. aureus was obtained from the skin of patients at Abdul Moeloek General Hospital. An antibiotic susceptibility test was performed by the disk diffusion method. Biofilm formation of S. aureus was tested using the crystal violet method. The viability of pathogenic bacteria was measured using the indicator resazurin. The results of the biofilm formation test in vitro revealed that the organic extracts 33A1T2, 33A2T3, 21A1T11, and 38A1T12 inhibited bacterial growth at 0.5 mg/mL. Meanwhile, 50A2T9, 21A1T11, and 38A1T12 significantly inhibited the formation of staphylococcal biofilm on polystyrene at a concentration of 0.25 mg/mL. This information is very important as a basis for further understanding of the mechanism of action of antibiofilm agents.

Published: December 2021

Abstract
The tourism sector is the economic sector hardest hit during the Covid-19 pandemic. A breakthrough is needed in line with health protocols to maintain physical and social distance. Tourism on the outermost islands is an alternative solution. As the largest archipelagic country globally, Indonesia has the potential for the outermost islands that can be used as tourist destinations. A breakthrough policy is needed in the management of ecotourism in the outermost islands related to the limited capability of the Government, such as the high costs for transportation and logistics arrangements in the outermost islands. Tourism in the outermost islands must be directed towards premium tourism. Its market share is middle to upper-class tourists who want a new atmosphere and challenges and are willing to pay quite a lot of money. This study presents a management model that divides each government agency’s duties in managing ecotourism in the outermost islands with a premium scheme and the National Border Management Agency being the operator. The model is expected to encourage the formulation of targeted policies for the management of the outermost islands, including the presence of cruise ships.

Unir Sirau Subdistrict has the highest percentage reaching 73.37%. The purpose of the study was to analyze human resource factors and local food management to accelerate stunting prevention in Asmat. This research is qualitative with descriptive method. The sampling method is purposive sampling. Data collection was done by interview according to online interview. Results of the interviews state that the high incidence of stunting in Asmat are the influence of people’s habits who still sell their catches and gardening, such as fish, vegetables, corn, etc., to buy less nutritious foodstuffs. Mothers don’t know prepare healthy food for children, often diarrhea due their habit of not washing hands and not having clean water. People are unmotivated to take part in posyandu activities and health education. People come to health services only when the child’s bad condition. Conclusion that stunting can be reduced give education is interesting and direct counseling to monitor people’s lives, provide financial assistance and healthy food is done on a regular basis until the bad habits of the community disappear.
Surface and corrosion properties of Type 430 ferritic stainless steel in parsley (Petroselinum Sativum) essential oil-containing sulphuric acid solution
Authors: Sanni Omotayo , Ren Jianwei , Jen Tien-Chien 
Published: December 2021

Abstract
This study examined the corrosion inhibiting properties of parsley (petroselinum sativum) essential oils, for Type 430 ferritic stainless steel in 0.5 molar sulphuric acid solutions. In this study, weight loss, electrochemical and scanning electron microscope techniques were used in gaining a detailed understanding of inhibition effects of parsley (petroselinum sativum) essential oils (PEO) on Type 430 ferritic stainless steel corrosion. The inhibitor studied exhibits good anti-corrosion performance with 98.65% inhibition efficiency. This result could be ascribed to the adsorbed PEO on the surface of the stainless steel, and this was verified by surface visualization using optical and scanning electron microscope techniques while the crystallographic variation of the inhibited sample is studied by x-ray diffraction (XRD). The adsorption of PEO onto stainless steel surface is controlled by Langmuir adsorption isotherms. Optical images of non-inhibited specimens showed a severely corroded surface with a visible macro pit on the stainless steel from sulphuric solutions. The inhibited sample shows improved surface owing to the surface protection effect of PEO molecules. The corrosion inhibition performance of PEO is due to the presence of active constituents which enhanced the film formation over the surface of the metal, thus, mitigating corrosion.
Synergistic performance of expanded graphite—mica amalgamation based non-asbestos copper-free brake friction composites
Authors: Sathyamoorthy G , Vijay R , Lenin Singaravelu D 
Published: December 2021

Abstract
Recent advancements in brake pad applications emphasise various friction compositions that exclude toxic components such as asbestos, copper etc, in order to provide superior performance without hurting the environment, human life and aquarium species. In this work, brake friction materials were fabricated by the conventional manufacturing process as standard brake pads using expanded graphite with the synergetic effect of thermal resistant material mica flakes. Six standard brake pads were produced based on varying the expanded graphite by 16, 14, 12, 8, 6 & 4 weight percentage, which is compensated using the Mica flakes by 4, 6, 8, 12, 14 & 16 weight percentage, fixing the composition of other ingredients and designated as BM01, BM02, BM03, BM04, BM05 and BM06. Physical, chemical and mechanical, characterisations of the formed friction materials were carried out in accordance with IS 2742 and ISO 6312. A full-scale inertia brake dynamometer was used to determine the fade, recovery characterisations with the pressure and speed sensitivity as of JASO-C-406. From the experimental observations, BM03 friction composites reveal excellent low fade and high recovery characteristics because of the integrated effect of expanded graphite (superior lubricity) & mica (good thermal stability). Worn surface analysis was studied with the help of a scanning electron microscope. The inclusion of expanded graphite-mica as a hybrid ‘lubricant-filler’ combination in composite materials for friction braking application results in performance synergism.

Abstract
Pure bismuth ferrite (BiFeO3, BFO) and ZnO thin films, as well as BFO/ZnO and ZnO/BFO composite thin films were successfully deposited by a sol-gel process on Pt/Ti/SiO2/Si and FTO/glass substrates, respectively. The chemical composition, surface morphology, optical properties, and multiferroicity were systematically investigated. X-ray diffraction and electron microscopy measurements were used to determine the crystalline phase and to analyze the surface morphology. Evidently, the absorption edges of both BFO/ZnO and ZnO/BFO films show a redshift, broadening the absorption range. The leakage current density decreases with the introduction of ZnO, and the ferroelectricity was significantly improved of the bilayers. Thereinto, BFO/ZnO and ZnO/BFO show the highest saturate polarization (2P
s) of 46.7 μc cm−2 and the maximum remanent polarization (2P
r) of 18.5 μc cm−2, respectively. Meanwhile, the magnetization measurement revealed that both BFO/ZnO and ZnO/BFO exhibiting an enhanced magnetization, especially, BFO/ZnO displays the highest saturation magnetization (2M
s, 68.87 emu cm−3) and remanent magnetization (2M
r, 4.87 emu cm−3).

Published: December 2021

Abstract
Welding operation decides the quality of product standards in all metal work products like automobiles, aerospace vehicles, and many more. The quality of the welding process is more reliable by automating the process with robots. In this research work, the GMAW operation is automated with the ‘Fanuc Robot Arc mate 100iC/12’ robot. The material characteristics such as ultimate tensile strength, hardness, and impact strength of weldments are predicted using a fuzzy system using triangular membership function (TrMF) and trapezoidal membership function (TMF). The simulated results are validated by comparing with experimental work, the experiments are designed using orthogonal array L18, and material characteristics are studied using fractography test. The fuzzy system is trained with experimental results using the IF-Then rule base with the help of the L18 orthogonal array. The inference system has predicted the accuracy rate of weldment mechanical properties, showing a lower error rate.
