This study examines the gap between Nestlé’s sustainability commitments and the reality of ecological damage caused by the use of unsustainable raw materials in its global supply chain. Using a descriptive qualitative approach based on literature reviews and case study analysis, this study evaluates various data sources, ranging from scientific journals and corporate reports to documentation from independent organizations such as Greenpeace and the Rainforest Action Network. Findings indicate that Nestlé’s procurement of key commodities such as palm oil, cocoa, soy, dairy products, and singleuse plastics significantly contributes to deforestation, systemic plastic pollution, water extraction in vulnerable regions, and greenhouse gas emissions exceeding 87.5 million tons of CO₂e per year. In Indonesia, these highrisk areas are evident in palm oil sourcing in Sumatra and Kalimantan and cocoa sourcing in Sulawesi. Theoretically, this study argues that Nestlé’s sustainability governance exhibits a pattern of strategic decoupling, where public reporting on progress in primary supply chains is deliberately used to mask ongoing environmental damage within their hidden supply networks. Thus, this article makes a critical contribution by integrating supply chain management theory, environmental accountability, and the governance of multinational corporations.

The development of electric vehicle technology has encouraged the use of electric bicycles as an environmentally friendly and energy-efficient mode of transportation. One of the main components of an electric bicycle is the hub BLDC (Brushless Direct Current) motor, which is considered more efficient because it is directly integrated into the wheel without requiring a chain transmission system. However, the performance of the hub BLDC motor is affected by operating conditions, particularly variations in load and speed, which influence current consumption and overall electrical performance. This study aimed to analyze the effect of load and speed variations on the current consumption of a hub BLDC motor. A quantitative experimental method was employed by conducting direct tests on an electric bicycle using load variations of 50 kg, 60 kg, and 70 kg, as well as speed variations of 30 km/h, 35 km/h, and 40 km/h. Current measurements were carried out in real time using a PZEM 051 sensor, and the collected data were analyzed using average values obtained from repeated measurements. The results showed that increasing the load and speed led to higher current consumption of the hub BLDC motor, from 4.6 A to 5.0 A under load variation and from 4.5 A to 5.1 A under speed variation. These findings indicate that both load and speed significantly affect the electrical current required by the hub BLDC motor, demonstrating that greater operating demands result in higher energy consumption.

The enactment of the Bharatiya Nyaya Sanhita, 2023 (BNS) and the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) represents a significant transformation in India’s criminal justice system. Although environmental protection in India has traditionally been governed by specialized environmental statutes, the newly enacted criminal laws also contain provisions capable of addressing environmental crimes and ecological harm. This article examines the role of the BNS and BNSS in promoting environmental accountability and strengthening green justice within India’s legal framework. The study adopts a doctrinal and analytical legal research methodology based on statutory interpretation, constitutional analysis, and judicial precedents. The research finds that provisions relating to public nuisance, water pollution, atmospheric contamination, hazardous substances, and acts likely to spread disease collectively establish a broader criminal law framework for environmental protection. Judicial interpretation of Article 21 of the Constitution, together with principles such as the polluter pays principle, precautionary principle, and sustainable development, has further strengthened environmental jurisprudence in India. The article argues that the BNS and BNSS contribute toward mainstreaming environmental protection within criminal law, but effective enforcement, institutional coordination, and stronger implementation mechanisms remain necessary for achieving sustainable environmental justice.

This study aims to examine the strategic role of teachers in instilling anti-corruption educational values in elementary school (SD/MI) students in the digital era. Employing a descriptive qualitative approach, data were collected through in-depth interviews with five SD/MI teachers in Karawang Regency conducted in May 2026.
