Abstract

The increasing degradation of the environment and growing demand for sustainability have shifted the paradigm in assessing corporate performance. Sustainability has three dimensions beyond profit, called the triple bottom line. The mining sector has critical strategic significance for economic growth, although entwined with high environmental hazards. Using EViews tool, this study explores green accounting and environmental performance's impact on financial performance of the business. Despite being based on data from financial statements, annual and corporate sustainability reports, the results are of paramount importance and read like this. These studies show that environmental performance has a strong and positive impact on financial performance, confirming the financial relevance of sustainability initiatives. In contrast, green accounting methods have no significant effects on financial results, indicating a disconnect between conventional accounting scopes and viable eco-initiatives. Collectively, these factors have a material impact on corporate performance. The research sectoral focus and sample confines its generalisability. Future studies need to explore intervening or moderating models and incorporate further variables in order to deepen understanding and broaden applicability. Our study adds to the existing literature debates about how environmental sustainability can be reconciled with corporate financial performance.

Abstract

In the palm oil industry, three-phase induction motors have a very important role in the production process. One of the problems that arises is the quality of the loading power on the motor which can make the motor performance less than optimal. In this study, an analysis and calculation of the power of a three-phase induction motor were carried out with the condition of opening the control valve in stages from 0% to 100%. The motor to be discussed is a three-phase induction motor that works as a pump driver for transferring crude glycerine water to the tank farm at the fatty acid 2 plant at PT. Unilever Oleochemical Indonesia. By using the observation method in conducting research to obtain measurement data, the variables taken are changes in current, power factor, and input power. From the results of this study, the output power value and power efficiency on the motor were obtained when the valve was opened 0%-100%, at the highest valve opening      of 100%, the motor output power was 4.39 KW with a power efficiency on the motor of 95%, at the lowest valve opening, the motor output power was 3.22 KW with an efficiency value obtained 95%.

Abstract

Probiotics  are  microbes  that  are  alive  and  beneficial  to  their  hosts.  Some  probiotic  bacteria  are  Lactobacillus  plantarum  and  Lactobacillus  acidhopillus.  The  performance  of  these  two  bacteria  will  be  optimal  if  prebiotics  are  added  as  a  source  of  nutrition,  namely  kepok  banana  (Musa  acuminata  ×  balbisiana).  The  aim  of  the  research  was  to  analyze  the  comparative  physicochemical  and  microbiological  properties  of  fermented  goat's  milk  using  Lactobacillus  plantarum  and  Lactobacillus  acidhopillus  with  prebiotic  kepok  banana  puree  (Musa  acuminata  ×  balbisiana).  The  study  used  a  completely  randomized  design  with  a  factorial  pattern,  factor  A  percentage  of  kepok  banana  puree  P1=  5%  kepok  banana  puree,  and  P2=  15%  kepok  banana  puree,  factor  B  V1=  Lactobacillus  plantarum  (5%)  and  V1=  Lactobacillus  acidhopillus  (  5%),  done  3  times  repetition.  The  results  of  the  research  were  that  adding  15%  kepok  banana  puree  to  Lactobacillus  plantarum  was  better  at  increasing  lactic  acid  levels  and  bacterial  growth  in  the  Total  Plate  Count,  and  15%  kepok  banana  puree  to  Lactobacillus  acidophilus  was  better  at  lowering  pH,  increasing  protein  levels,  reducing  syneresis  and  increase  the  viscosity  value.  The  conclusion  of  this  research  is  that  the  use  of  15%  can  improve  the  performance  of  Lactobacillus  plantarum  and  Lactobacillus  acidhopillus,  and  in  general  all  research  parameters  are  still  within  the  Indonesian  National  Standard  range. These findings contribute to the advancement of food science and microbiology by demonstrating the potential of kepok banana puree in improving the quality of goat milk-based probiotic products.

Abstract

Business competition in the restaurant sector continues to experience quite rapid development, which means businesspeople have to be careful when making decisions. Therefore, the purpose of this study is to find out and analyze the influence of raw material quality, product quality, and price on purchasing decisions with competitive advantage as an intervening variable in Silungkang Restaurant. The sample of this study is 100 consumers of the Silungkang Restaurant. The model of this research is structural equation modeling (SEM), with an analysis tool using SmartPLS 3. The findings of this study show that raw material quality, product quality, and competitive advantage have a positive and significant influence on purchasing decisions. In addition, it was also found that the quality of raw materials, product quality, and price had a positive and significant effect on competitive advantage. Meanwhile, price has an effect, but significantly, on the purchase decision. For the indirect influence through the competitive advantage variable, it was found that competitive advantage could not play a role in strengthening the influence of price on purchasing decisions. However, indirect influence through competitive advantage variables, a significant influence was found on the quality of raw materials and product quality on purchasing decisions.

Abstract

Ternate Island is part of the administrative area of Ternate City, North Maluku Province which was once the capital of the province and the center of government continues to experience physical development. This study aims to analyze the development of urban growth in Ternate Island in the period 2004-2032. The cellular automata markov chain method uses 2004, 2014 and 2024 land cover data and driving factors consisting of elevation, slope, distance from road and distance from POI to predict urban growth. The results of the analysis show that the urban area continues to increase in area, namely in 2004 the urban area had an area of 1,424.14 ha, 2014 an area of 1,728.45 ha and in 2024 an area of 2,010.78. The prediction results of urban growth on Ternate Island in 2032 show that the urban area has an area of 2,884.37 ha. Based on the research results from the application of the markov chain cellular automata method, it is hoped that these findings can be taken into consideration in designing a sustainable spatial arrangement of Ternate City. So that ecological balance, environmental balance and food security can be maintained and meet the requirements of a city that has the carrying capacity and environmental capacity.

Abstract

This study aims to analyze the role of Quality Education in forming a generation of young leaders through Basic Student Leadership Training (LDKS) implemented in the Asriloka Wonosalam Ecotourism Area. Using the Systematic Literature Review (SLR) method with a comparative qualitative descriptive approach, this research examines various literatures related to leadership education, ecotourism, and sustainable development. The results show that the integration of the Quality Education concept in ecotourism-based LDKS contributes significantly to building adaptive, innovative and sustainability-oriented leadership characters. LDKS participants gain direct leadership experience through experiential learning, which includes managerial skills, decision making, problem solving, and social and environmental awareness. In addition, the ecotourism area provides a supportive learning environment, where participants can develop conservation-based leadership skills, green entrepreneurship, and community empowerment. The implication of this study confirms that the ecotourism-based LDKS approach can be an effective alternative education model in producing young leaders who are not only smart and competitive, but also have high concern for the environment and society. Therefore, it is necessary to strengthen the curriculum, increase collaboration between educational institutions, ecotourism managers, and local communities, as well as continuous evaluation to ensure the effectiveness of the program in the long term.
