: As part of a poverty alleviation program enshrined in the global sustainable goals numbers one and two, Sedayulawas Village in the Lamongan Regency was selected as a pilot project with abundant agricultural land for crops such as corn, tubers, beans, and collecting salt. However, the declining institutional governance in the farming sector due to conflict has been brought on by the COVID-19 pandemic. To figure out the quality of life (QOL) of the people in Sedayulawas Village, an evaluation was done using a questionnaire about QOL and food security. This strategy completely accomplishes its goals of providing information, identifying food security, and measuring it. This study also evaluates the impact of food security on residents of Sedayulawas Village who work in agriculture. A confirmatory factor analysis (CFA) approach was used, followed by analysis in SEM-PLS with smart-PLS software to develop the resultant model. The results show a positive result of the link between the QOL and food security, with the most important material variable having an effect of 77.9%. Therefore, increasing household food security for farmers is a to their subjective well-being and encourages human capital accumulation. This positively affects productivity and helps keep farming in rural Indonesia sustainable. Food insecurity in rural areas can be reduced by conducting research, developing mitigation strategies, and implementing them. To advance food security at the village level, several programs must be implemented by the government, including readiness programs that reduce hunger risk and improve quality of life.

: A high quantum yield of up to 20% N-CDs from plastic bag waste has been synthesized via the pyrolysis-hydrothermal method. Using plastic bag waste as a carbon source offers several advantages, including their abundant availability, low cost, and potential to reduce plastic waste in the environment. The effect of hydrothermal time and H 2 O 2 concentration as an oxidant was evaluated. The N-CDs acquired exhibit a consistent blue fluorescence, possess an average dimension of 5.94 nm, and consist of graphitic structures that may contain flaws induced by surface functional groups such as amine, imine, alcohol, carboxyl, and carbonyl. Excellent stability of the resulting N-CD toward storage time, NaCl, and phosphate buffered salt (PBS) solution pave the way to possible applications for metal ions sensing in wastewater and human cells.

: Nusantara is the future capital of Indonesia, located on the east coast of Borneo in East Kalimantan province. As of July 2022, Nusantara construction began, with the first phase of clearing land and installing roads. As a matter of fact, Indonesia’s main problem is its high energy consumption. Over one-third of the country’s energy consumption is consumed by buildings. Therefore, energy-saving strategies will be essential to making the cities more sustainable, especially in Nusantara. Since Nusantara was planned to be a model sustainable city that could serve as an example for other Indonesian cities. An analysis of tropical-climate residential building design is presented in this paper. A strategy for energy-efficient buildings is outlined based on literature analysis and results from a case study in tropical cities. An energy simulation analysis shows that middle-rise residential houses adapted from Lamin houses will likely consume less electricity (8%) than typical apartment buildings. The simple adaptation of a traditional local building, Lamin house, to a modern mid-rise residential building suggested an open plan with a long and narrow floor plan, overhang over the window, and cross ventilation through window openings.

: The small-scale low-pressure biodigester is emerging to meet the energy needs of small households. It is important to standardize the biodigesters primarily to protect consumers and provide good quality biogas. The purpose of this research was to determine the quality requirements for the small-scale low-pressure biodigester. The research was conducted using interviews with respondents who are biogas practitioners. Questions from the questionnaire related to the quality parameters of biodigesters. The result generally showed that more than 80% of respondents accepted the quality requirements proposed. Furthermore, the quality requirements from this research will be proposed as the Indonesian National Standard (SNI) .

: The purpose of the study is the examination and detailed analysis of the methodology for assessing the intensity of climate change, its impact vectors at the global, regional and local levels, and the search for possible optimal solutions of a preventive and liquidation nature to minimise negative consequences. The study was conducted using general scientific methods of cognition, namely system analysis, synthesis, abstraction, generalisation, concretisation, and formalisation. The study examines the issues of adaptation to global climate change in Central Asia, in particular, in the Republic of Uzbekistan. The study determined the degree of increase in warming indicators and its impact on degradation processes in the Aral Sea and glacial melting in the region. The use of the developed formula for assessing climate change intensity at the regional level is justified, providing a basis for preventive and eliminative actions. The study's results are practically important for optimizing the National Adaptation Plan and the National Drought Management Plan. Therewith, the priority is the synergy of the goals of environmental prevention and economic feasibility, considering modern innovative opportunities for modelling, forecasting, and the direction of the development vectors of Uzbekistan towards a positive global trend of sustainable development and the prevention of climate change.

: Lubrication is a technique of using a lubricant to reduce friction & wear. There are four major lubrication regimes i.e., boundary, mixed, elasto-hydrodynamic & hydrodynamic. Most of the industrial machines & equipment’s moving surfaces in contact, works in the mixed lubrication regime. Almost the entire major breakdown related to surface pitting & wear resulted from high friction occurs in this regime only. A lot of study & research is required in this field for improving the tribological performance of the surfaces in contact. Hardness of the base material always plays an important role in the performance of the tribological pair in all lubrication regimes especially in mixed lubrication. Therefore, authors consider the tribo pair of brass & EN31 as base material for conducting the study of the effect on various tribological parameters in mixed lubrication regime with VG-46 lubricant. Authors have also focused themselves to investigate the effect of the hardness of the base material (EN31) on the friction & wear parameters for the above mentioned tribo pair & lubricant in mixed lubrication regime because of its wide practical & industrial applications in most of the equipment & machines Also, this tribological pair is the most imperative pair used in enormous industrial applications. VG-46 is also an effective lubricant used in various industrial setups.
