Abstract

Hate speech is a form of abusive language and toxic language aimed at individuals, groups, races or ethnicities, genders and certain religions. The problem that occurs is the absence of a good filtering process on social media. For this reason, a filtering process is needed that aims to distinguish between video content that contains hate speech or not. The filtering process can use a classification model. This classification model uses an artificial intelligence algorithm. The purpose of this study is to conduct a literature review on algorithms that can be proposed for detecting hate speech videos. The algorithm used refers to the concept of green technology, with low energy resource consumption and minimizing negative environmental impacts. The literature study conducted obtained the CNN, BERT and LSTM algorithms for the hate speech video classification model. The three algorithms can be used as a reference to obtain a Green AI model by considering the low performance indicator parameters on the CPU, or using a fusion level that can reduce CPU performance. This is in accordance with the concept of green technology, reducing the use of computing processes that absorb large amounts of electrical energy.

Abstract

The Energy-Efficient Solar Lamp (LTSHE) initiative is a strategic electrification program implemented by the Indonesian government to deliver sustainable lighting solutions to rural communities in Sulawesi that remain beyond the reach of the national electricity grid. The program primarily targets residents in remote, underdeveloped, and isolated areas, including border regions and small frontier islands. The LTSHE system utilizes photovoltaic panels to capture solar energy, which is converted into electrical energy and stored in lead-acid batteries through a capacitor hub, subsequently supplying power to LED lamps for household illumination. To assess system performance, a photometric evaluation was conducted on a sample representing 6,018 installed systems (24,072 lamp units). As of July 31, 2018, nine units (0.037%) were randomly selected for laboratory testing. Illumination intensity was measured at three dimming levels (100%, 50%, and 10%), producing average illumination values of 31.6 lux, 15.4 lux, and 3.2 lux, respectively. Measurements at reduced dimming levels demonstrated consistent light output across samples, with values ranging from 14.4 to 14.8 lux at 50% and approximately 2.8 lux at 10%. Laboratory verification also indicated that the measured direct current injection voltage (8.10 V) exceeded the manufacturer’s specified minimum of 7.40 V, confirming the accuracy and reliability of the testing instruments. Overall, the findings demonstrate that LTSHE units provide adequate and consistent illumination, particularly at lower dimming settings, supporting their suitability for off-grid rural applications in Sulawesi. Future evaluations are recommended to standardize testing across all dimming levels to ensure comprehensive performance validation.

Abstract

Industrial activities potentialy cause river water pollution which can have a negative impact on riparian ecosystems. This study aims to analyze the effect of distance of sugar industry pollutant sources on water quality and riparian vegetation diversity in Sukun River, Malang Regency. Sampling was conducted at three stations located 2 km from each other. Vegetation analysis was conducted using the Index of Important Value (INP), Shannon-Wiener Diversity Index, and Index of Riparian Quality (QBR). The results showed that the farther away from the pollutant source, the better the water quality and riparian vegetation. The highest DO was found at the farthest station (6.8 mg/L), while the lowest was at the nearest station (1.17 mg/L). The Shannon-Wiener diversity index and QBR also increased with distance from the pollutant source. Correlation analysis showed a negative relationship between pH and riparian vegetation quality, and a positive relationship between DO and TDS and vegetation diversity. Overall, this study confirms that industrial pollution has a significant impact on river ecosystems. Therefore, effective environmental management strategies, such as rehabilitation of riparian areas is needed to maintain the river ecosystem and support the biodiversity preservation and ecological balance along the Sukun River.

Abstract

Hatcheries designed to be fair-trade, sustainable, well adapted to sunny countries and operating mainly through thermosiphon flows generated by solar radiation or radiative emission at night, were recently the subject of a theoretical study. The dimensionings of their incubator, solar collector, night and heat discharge radiators, water reserve and chassis for the climatic conditions in Cameroon and Indonesia were deduced from this. However, some secondary but essential functional aspects of the implementation of these hatcheries were not addressed. To facilitate their use and operation, a turbine is used here to check whether the thermosiphon flows take place and what is their intensity. The use of the thermosiphon flow control turbines is proven to give important advantages. Firstly, this design support a more eco-friendly environment by being energy neutral. Secondly, this design uses simple, cheap, and long-lasting materials. As a result, this fair-trade sustainable hatchery represents the environmentally friendly and affordable solution, especially for third world countries such as Cameroon and Indonesia. This will help to realize sustainable development goals, especially SDG 7 (clean and affordable energy).
