Abstract

The increasing number of motorcycles in Indonesia contributes to air pollution, including exposure to particulate matter and ultrafine particles that may affect human health (Schraufnagel, 2020; Masruroh, 2015). This study developed and evaluated ORFIL, a natural air filter made from cocopeat (coconut husk waste) and rice straw, to reduce motorcycle exhaust emissions. The filter material was prepared by dehydrating 70 g cocopeat and 70 g straw for 48 hours, grinding each into coarse powder, mixing them, and packing the mixture inside a factory filter frame using tulle fabric as a retaining layer. Emission performance was tested on one motorcycle (motorcycle X) by comparing the factory-installed foam filter and ORFIL using measured exhaust parameters (CO, HC, CO₂, and O₂). The ORFIL filter produced lower emissions than the factory filter: CO decreased from 0.04% to 0.027%, HC decreased from 19 ppm to 15 ppm, and CO₂ decreased from 0.6% to 0.48%, while O₂ increased from 20.41% to 22.2%. These results indicate that cocopeat and rice straw have practical potential as low-cost natural filter media, consistent with prior findings on coconut fiber and straw-based filtering materials (Lay & Pasang, 2003; Wahyuningrum et al., 2014; Surjosatyo, 2020).

Abstract

Children with intellectual disabilities require specialized educational support to develop self-help skills, basic academic abilities, and emotional regulation. However, the availability of interactive learning media that integrate these developmental aspects remains limited. This study aimed to develop Bhāra Book as an interactive learning medium designed to support self-help skills, pre-literacy, pre-numeracy, and emotional recognition for children with intellectual disabilities. This research employed a qualitative approach, with data collected through direct observation and in-depth interviews involving teachers and parents at several special schools (SLB) in Cianjur Regency. The findings indicate that Bhāra Book provides practical support for daily self-care training, basic academic learning, and emotional reflection. Observations showed positive engagement from children with mild intellectual disabilities, while feedback from teachers and parents highlighted the usefulness, simplicity, and visual appeal of the media. The results suggest that Bhāra Book contributes to diversifying learning media and supports the rights and opportunities of children with intellectual disabilities to optimize their development.

Abstract

Air pollution is an increasing environmental problem caused by industrial activities, transportation, and human daily activities. One alternative approach to monitoring air quality is the use of bioindicators, which are living organisms capable of reflecting environmental conditions. Mosses have strong potential as air bioindicators because they lack true roots and absorb nutrients directly from the atmosphere, allowing pollutants to accumulate in their tissues. This study aimed to examine the ability of mosses to accumulate air pollutants and to compare air pollution levels across different environments. A descriptive-experimental method was applied by collecting moss samples from industrial areas, high-traffic zones, residential areas, and green spaces. The results showed that pollutant accumulation in moss tissues was higher in industrial and high-traffic areas compared to residential and green areas. These findings indicate that mosses can be utilized as simple, economical, and effective natural bioindicators for air quality monitoring.

Abstract

Essential oils are aromatic compounds produced by plants and widely used in cosmetics, perfumes, pharmaceuticals, and aromatherapy due to their bioactive properties. Sakura flowers (Prunus serrulata) contain phenolic and aromatic compounds with potential antioxidant and aromatic value. This study aimed to produce essential oil from sakura flowers collected at Cibodas Botanical Garden and to analyze its physical and aromatic characteristics. An experimental descriptive method was applied using steam distillation with a Clevenger apparatus. Fresh sakura flowers were processed to obtain essential oil, and the resulting product was evaluated based on yield, color, aroma, density, and refractive index. The results showed that the essential oil yield ranged from 0.2–0.5% (v/b) with a pale yellow to golden color and a characteristic floral aroma. These findings indicate that sakura flowers from Cibodas Botanical Garden have potential as a source of essential oil and may be utilized for cosmetic, aromatherapy, and fragrance applications.

Abstract

This study aimed to formulate and evaluate a natural antiseptic spray using plant-based ingredients derived from vetiver (Vetiveria zizanoides) and rose (Rosa damascena). The research was conducted as a school-based project focusing on simple formulation and descriptive observation rather than advanced laboratory analysis. Vetiver extract was obtained through a basic steam distillation process, while rose extract was prepared using water-based maceration. Both extracts were combined with a bioethanol-based solvent to produce a natural antiseptic spray formulation. The evaluation of the product focused on observable characteristics, including aroma, appearance, ease of use, and user response. Limited testing was carried out through non-clinical observation to assess user acceptance and potential irritation after short-term use. The results showed that the antiseptic spray had a pleasant natural aroma and was well accepted by users. No visible adverse reactions such as redness, itching, or discomfort were reported during limited observation. Based on these findings, the formulated antiseptic spray demonstrates potential as a natural and environmentally friendly product for external use. However, this study did not include chemical composition analysis, antioxidant testing, or microbiological assays. Therefore, the results are limited to formulation outcomes and user acceptance. Further research involving controlled laboratory testing is recommended to evaluate the chemical properties and antimicrobial effectiveness of the product.
