Abstract

This article aims to evaluate the performance of the wastewater treatment plant (WWTP) operated by the pharmaceutical industry PT. X. The study assesses the effectiveness of wastewater treatment by testing water quality parameters from both the inlet and outlet, as well as analyzing each treatment unit, such as Oil and Scum Separation, Oil and Scum Collection, Equalization and Neutralization Tank, Aeration Tank, Clarifier, Break Tank, Filtration, Final Tank, and Sludge treatment units, including Sludge Collection and Stabilization Tank and Filter Press. Monitoring results show that PT. X’s wastewater meets the established quality standards. However, operational issues were observed, including overflow in the equalization and neutralization tanks, foam formation in the aeration tank, and sludge bulking in the clarifier unit, all requiring corrective actions. Recommended improvements include installing ultrasonic sensors, increasing dissolved oxygen (DO) concentration and the food-to-microorganism (F/M) ratio, and replacing filter media to optimize the treatment process. This evaluation is essential to ensure optimal wastewater treatment performance and compliance with environmental quality standards.

Abstract

Papaya (Carica papaya L.), a plant commonly found in Indonesia, holds potential as an active ingredient in the pharmaceutical field, particularly in the environmentally friendly synthesis of silver nanoparticles. This study explores the ability of papaya leaf extract to act as a natural reducing agent through a green synthesis method, utilizing the flavonoid content it contains. The extract, obtained through an infusion process, was mixed with a 5 mM AgNO₃ solution at a specific ratio, and the formation of nanoparticles was indicated by a change in the solution’s color. Measurement using UV-Vis spectrophotometry at a wavelength of 350 nm showed a maximum absorbance value of 0.684, confirming the formation of silver nanoparticles. Thus, papaya leaf extract is proven to function effectively as a bioreductor in the synthesis process. Green synthesis offers a green alternative for the production of silver nanoparticles that is safer and more environmentally friendly. This research demonstrates great potential in the development of sustainable green technology in Indonesia by utilizing abundant natural resources. The results of this research can serve as a basis for further development in the application of silver nanoparticles in the fields of pharmacy and health, as well as increasing the economic value of papaya plants (Carica papaya L.). This also open up new opportunities for further research.

Abstract

Musi Rawas Regency is one of the regencies that has experienced significant growth in agriculture, especially rice. The choice to sell in the form of grain or rice is a strategic decision for farmers because it concerns production efficiency, potential profits, and risks that must be faced. This study aims to provide a comparative analysis quantitatively and qualitatively of both forms of sales, including considering cost factors, distribution models and supporting institutions in Musi Rawas Regency. The determination of the farmer sample in this study used purposive random sampling of 75 people. The data sources in this study used primary and secondary data The research results show that selling unhusked rice is more profitable for farmers if done directly, with a 100% profit margin (farmer to Bulog). Unhusked rice sales are more profitable because they don't require post-harvest activities. This differs from selling rice, which requires post-harvest handling and therefore incurs costs. There are three profit comparison models for rice sales: 70%/30%, 50%/50%, and 30%/70%. The largest marketing margin is located in marketing channel 1, with a total margin of Rp 5,300, while the smallest total margin is in marketing channel 3, namely Rp 2,000. From the analysis results, it is known that the marketing margin of agricultural products is influenced by the number of marketing institutions involved, transportation costs. High margins do not necessarily indicate inefficiency, but may reflect the high operational costs and risks borne by intermediaries.

Abstract

Laboratory wastewater at the Environmental Engineering Study Program of Jember University (UNEJ) is wastewater generated from various practical activities and research involving the use of inorganic and organic chemicals. UNEJ Environmental Engineering laboratory wastewater is used as a means of supporting lectures and research for students and lecturers. The UNEJ Environmental Engineering Laboratory has never conducted tests on the characteristics of the wastewater produced. This study aims to examine the effectiveness of sugarcane bagasse in adsorbing COD levels in laboratory wastewater at various adsorbent heights and activator variations. The initial COD content of the laboratory wastewater was 665 mg/L. The variations in adsorbent height in the adsorption column reactor were 2 cm, 3 cm, 4 cm, and 5 cm, while the variations in sugarcane bagasse adsorbent activators were HCl, H3PO4, KOH, and Na2CO3. Based on the results of the study, the best COD removal efficiency was achieved with a column height variation of 5 cm and a KOH activator variation of 92.05%. The COD content in the initial laboratory wastewater of 665 mg/L after undergoing the adsorption process using bagasse waste adsorbent became 52.9 mg/L.

Abstract

Stunting is a serious global problem affecting more than 160 million children under five worldwide. In Aceh Singkil, the stunting rate reached 34.01% (SKI, 2023). This study aims to determine the risk factors associated with stunting in toddlers aged >6–59 months in the Gunung Meriah Community Health Center, Aceh Singkil Regency, in 2025. This study used a descriptive analytical design with a cross-sectional approach. A sample of 98 respondents was selected randomly from the population of mothers with toddlers. Data collection was conducted through interviews and observations using questionnaires and measuring instruments, and analyzed using the chi-square test in the SPSS application. The results showed a stunting prevalence of 38.8%. Factors that had a significant relationship with stunting were complete basic immunization (p = 0.002) and exclusive breastfeeding (p = 0.002). Meanwhile, maternal knowledge, parenting patterns, and information sources did not show a significant relationship. The results of the multivariate analysis showed that immunization has a statistically significant relationship with the incidence of stunting, with a p-value of 0.002 and an OR of 3.846, meaning that toddlers who do not receive immunization have a 3.8 times greater risk of experiencing stunting compared to toddlers who receive complete immunizations. It was concluded that exclusive breastfeeding and complete immunization play an important role in preventing stunting. Therefore, it is recommended that the Health Office strengthen education regarding the importance of exclusive breastfeeding and immunization, as well as encourage parental involvement in monitoring children's growth and development.

Abstract

This study assesses ambient PM2.5 concentrations alongside temperature and humidity at two campus sites, UPN and UGM, utilising a Low-Cost Sensor (LCS) IoT-based device.  LCS-IoT provides a cost-effective and sustainable solution for air quality monitoring, addressing the shortcomings of costly traditional sensors.  Data indicates considerable daily fluctuations in PM2.5 concentrations; UPN documented morning peaks surpassing 100 µg/m³ at approximately 08:00 AM, but UGM exhibited lower peaks, remaining below 45 µg/m³ during the same timeframe.  This discrepancy is associated with the positioning of UGM's sensors within the campus's Green Open Space (RTH)/vegetation zone, whereas UPN is situated adjacent to a bustling roadway.  This observation highlights the effectiveness of green spaces and vegetation in reducing PM2.5 pollution.  The temperature trend at both analogue locations peaked at 31-33°C during the day.  Relative humidity exhibits an inverse correlation with temperature, peaking at 80-90% during the early morning and declining to a low of 59-70% during the day.  The research findings underscore the significance of air quality monitoring within the campus environment and the necessity for specific mitigation strategies to safeguard the health of the academic community.  Extended research with prolonged measuring periods is recommended for a more thorough comprehension.

Abstract

Soil characteristics play a crucial role in determining soil fertility status, land capability, and sustainable land management strategies through the assessment of physical, chemical, and biological properties. Land management practices in oil palm plantations directly affect plant growth and productivity as the plantation ages. This study aims to identify and evaluate the physical and chemical properties of soils under different oil palm planting ages. The research was conducted in Batu Belah Village, Kampar Regency, Riau, using three age categories: T1 (1–5 years), T2 (5–10 years), and T3 (>15 years). A survey method and direct field observations were employed to determine soil sampling locations. The physical parameters measured included texture, bulk density (BD), particle density (PD), total pore space (TPS), fiber content, and moisture content. Chemical parameters included N, P, K, organic C, pH, Pb, and Cd. The results showed significant changes in several soil physical and chemical properties with increasing plant age. These findings indicate that the evaluation of soil characteristics can guide the development of appropriate soil management strategies to support sustainable productivity in oil palm plantations.

Abstract

Pain is a natural signal to tissue damage in the body. One of the plants that has the potential as a natural analgesic is the pacing tawar flower (Costus speciosus) which is known to contain compounds that play a role in providing analgesic effects. This research method uses a pre-post test design to see the effectiveness before and after being given a test suspension in the form of (mefenamic acid, Na CMC, and ethyl acetate fraction of pacing tawar flowers at doses of 125 mg/kgBB, 250 mg/kgBB, and 500 mg/kgBB) in mice induced by pain with the tail flick method. The results of the phytochemical screening study showed that only the ethyl acetate fraction of pacing tawar flowers (Costus speciosus) was positive for containing flavonoid compounds with the formation of a yellow color compared to the n-hexane fraction and the water fraction. Functional groups identified in flavonoid compounds are C-H, C=O, C-O groups. Ethyl acetate fraction of pacing tawar flower at doses of 250 mg/kgBB and 500 mg/kgBB can provide analgesic effects with a p value (<0.05). Based on the research that has been done, it can be concluded that the ethyl acetate fraction of pacing tawar flower contains flavonoid compounds that can inhibit pain with the most optimal and stable fraction dose at a dose fraction of 500 mg/kgBB with a p value (<0.05).

Abstract

Vulgaris acne is a chronic inflammatory condition commonly experienced by adolescents and young adults, with a prevalence reaching up to 85%. Propionibacterium acnes plays a significant role in the inflammatory process of acne, which is influenced by sebum production, hyperkeratinization, and the inflammatory immune response. Acne treatment often involves antibiotics, but resistance to antibiotics such as erythromycin and clindamycin has increased, creating serious challenges in dermatology. Therefore, the development of non-antibiotic therapies for acne is crucial. One promising alternative is the extract of Mimosa pudica L., also known as the sensitive plant, which is recognized for its antimicrobial activity. The extract of Mimosa pudica L. leaves has been shown to inhibit the growth of various pathogenic bacteria and has potential anti-inflammatory effects based on in silico studies, opening up significant opportunities for the development of plant-based treatments for acne and other inflammatory diseases. This study aims to evaluate the effectiveness of ethanol extract of Mimosa pudica L. leaves in inhibiting the growth of Propionibacterium acnes ATCC 6919. The results of the study show that the 30% ethanol extract can inhibit bacterial growth with an inhibition zone diameter of 11.537 mm, indicating the potential of this extract as a safer and more effective alternative treatment for acne.

Abstract

Indonesia, as a tropical country, exhibits rainfall patterns that are strongly influenced by both global and regional atmospheric dynamics. The seasonal climate system in Indonesia, which consists of the wet season, dry season, and transitional periods, plays a crucial role in water resource management, agricultural activities, and disaster mitigation. To better understand these complex atmospheric and hydrological interactions, climatological parameters such as Equivalent Water Height (EWH) serve as important indicators of terrestrial water storage variability. The application of GRACE and GRACE-FO satellite missions provides a novel approach to monitoring hydrological dynamics through EWH, enabling large-scale and continuous observations of terrestrial water storage changes. The results of this study reveal a strong negative relationship between the Oceanic Niño Index (ONI) and EWH at zero time lag, indicating that El Niño events tend to reduce terrestrial water storage across Indonesia. This simultaneous response suggests that changes in atmospheric circulation during El Niño phases immediately affect hydrological conditions over land. In particular, the reduction in water storage is primarily associated with weakened moisture transport from both the Indian Ocean and the Pacific Ocean, which are the main sources of atmospheric water vapor influencing Indonesia’s climate system. As a result, decreased moisture convergence leads to reduced precipitation and a rapid decline in terrestrial water reserves. Bias evaluation further indicates distinct spatial patterns across the Indonesian region. Negative bias predominantly occurs in Sumatra and Kalimantan, whereas positive bias is more commonly observed in Nusa Tenggara and Maluku. In addition, the RMSE analysis shows that EWH estimates are relatively more accurate in regions with homogeneous rainfall patterns, while their performance decreases in areas characterized by high rainfall variability. These findings highlight the importance of considering regional climatic characteristics when interpreting satellite-based hydrological observations and emphasize the role of large-scale atmospheric–oceanic interactions in shaping terrestrial water storage dynamics in Indonesia.
