Abstract

This study modified current bentonite with zinc oxide (ZnO) and investigated the performance of phenol adsorption. The material bentonite-ZnO was successfully synthesized and characterized with X-ray diffraction (XRD), scanning electron microscopy-energy dispersive X-ray (SEM-EDX), and Fourier transform infrared (FT-IR). The adsorption performance was determined by adsorption equilibrium, kinetics, and thermodynamic parameters. The adsorption, kinetic, and thermodynamic parameters were compared alternatively. The phenol adsorption capacity was obtained from Langmuir and Freundlich adsorption isotherm models, which for bentonite-ZnO was fit with both isotherm models (Langmuir R2 = 0,997 and Freundlich R2 = 0,9515) and was favorable than activated bentonite (n value bentonite-ZnO = 2.389; activated bentonite = 0,898). A kinetic model was tested with pseudo-first-order, pseudo-second-order, and intraparticle diffusion models which bentonite-ZnO and activated bentonite fit in the pseudo-second-order with an excellent agreement (R2 = 0,999). Several thermodynamic parameters such as enthalpy, Gibbs free energy, and bentonite-ZnO have an entropy more than zero (ΔS = 0.008 J/molK), which demonstrated the feasibility and spontaneity (ΔG < 0) and endothermic nature (ΔH = 3,056 kJ/mol) of the phenol adsorption process.

Abstract

Stunting adalah kondisi gagal tumbuh pada anak balita akibat dari kekurangan gizi kronis sehingga anak terlalu pendek untuk usianya. Stunting masih menjadi fokus perhatian pemerintah Indonesia karena tidak hanya menyebabkan kelainan fisik namun juga kognitif yaitu berupa kecerdasan yang kurang pada balita sehingga saat dewasa akan menurunkan produktivitas. Metode yang digunakan melalui beberapa tahapan yaitu, 1) koordinasi dengan masyarakat dan toko masyarakat setiap dusun yang ada di Desa Jadi Mulya dalam menentukan perwakilan kader stunting setiap dusun, 2) Melakukan pelatihan kader stunting dengan metode penyuluhan dan demonstrasi di Balai Desa Jadi Mulya; penyuluhan tentang pencegahan dan penatalaksanaan stunting, penyuluhan antropometri gizi terkait stunting, serta demonstrasi pangan lokal dan bergizi, 3) Serah terima SK dari toko masyarakat desa Jadi Mulya kepada kader stunting. Tingkat pengetahuan kader diukur dengan melihat perbedaan skor pengetahuan sebelum dan sesudah pelatihan. Hasil kegiatan ini menunjukkan bahwa ada peningkatan tingkat pengetahuan kader stunting setelah diberi pelatihan dengan perubahan nilai rata-rata menjadi 87. Peningkatan pemahaman kader stunting terpilih tentang pencegahan stunting, serta komitmen para kader stunting sebagai agen perubahan yang merupakan bagian integral dalam mengurangi angka stunting, meningkatkan kesehatan di Desa Jadi Mulya dan perkembangan anak-anak di masa depan.

Abstract

Heavy metal pollution, including lead (Pb), zinc (Zn), and copper (Cu) in swamp environments, is increasing and poses a significant threat to ecosystem integrity and human health. This study aims to evaluate the phytoremediation potential of Eleocharis dulcis in accumulating heavy metals in root, stem, and leaf tissues. The experimental method involved growing Eleocharis dulcis for 20 days in media artificially contaminated with Pb, Zn, and Cu metals at concentrations of 5, 10, and 15 ppm. Observations were made on metal accumulation in plant tissues on days 5, 10, 15, and 20. The results showed that concentration and duration of exposure significantly influenced the pattern of metal accumulation. The highest accumulations were recorded in leaf tissue, specifically Pb at 87.527 mg/kg, Zn at 32.93 mg/kg, and Cu at 43.522 mg/kg. These findings indicate that Eleocharis dulcis has selective metal uptake and translocation mechanisms and high tolerance to heavy metal stress, and has the potential to be an effective phytoremediation agent for the rehabilitation of heavy metal-contaminated wetlands and support sustainable environmental management.

Abstract

The escalating contamination of heavy metals such as lead (Pb), zinc (Zn), and copper (Cu) in wetland ecosystems poses a significant threat to environmental integrity and public health. This study aims to assess the phytoremediation potential of purun tikus (Eleocharis dulcis) for the accumulation and reduction of these heavy metals in contaminated sediment and water matrices. An experimental approach was employed wherein purun tikus specimens were cultivated for 20 days in media artificially contaminated with varying concentrations of Pb (5, 10, 15 mg/L), Zn (80, 90, 100 mg/L), and Cu (80, 90, 100 mg/L). There was no significant difference (p > 0.05) in the accumulation of heavy metals Pb, Zn, and Cu in the roots, stems, and leaves of purun plants between treatment times of 5, 10, 15, and 20 days. The duration of treatment did not significantly affect the ability of purun plants to accumulate these heavy metals. The descriptive differences seen although not statistically significant are likely due to the small sample size and high variability of the data. The highest removal efficiencies were observed for Pb in stems (95.97%), Zn in roots (81.59%), and Cu in stems (66.10%). These findings indicate that purun tikus exhibits selective metal uptake and distribution mechanisms coupled with high tolerance to heavy metal stress, affirming its efficacy as a phytoremediator for rehabilitating heavy metal-contaminated wetlands and supporting sustainable ecosystem management.

Abstract

Nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), Particulate Matter (PM10) and TSP are the most common and harmful air pollutants to humans. In short period, air pollution exposure at 5 ppm for 10 minutes to humans causes dyspnea, and when the level is increase to 800 ppm could cause 100% mortality in animals. This study was an analytical research, with cross sectional design and risk analysis. One hundred subjects were analyzed in this study. The results showed that non-cancer Hazard Index (HI) for realtime exposure with mean value was NO2: 1.85; SO2: 2.92; TSP: 7.09; and PM10: 11.7 (HI value ≥1). The results of the analysis test for FVC lung capacity to non-cancer risk estimation of NO2, SO2, TSP and PM10 indicated that there was no significant relationship (p > 0,05). Variable of smoking habit is the most dominant variable (OR = 12,542) which affect respiratory disorders. The exposure of NO2, SO2, TSP and PM10 in Palembang City bus drivers is considered risky to non-cancer health subjects, so control is needed. This control could be performed by lowering the level of inhalation intake (I) of the RfC and the first simulation model for exposure could start from the second year to the sixth year.

Abstract

Pesticide poisoning, especially paraquat, is a significant health problem for agricultural workers, including sugarcane plantation workers in Indonesia. This study aims to evaluate the relationship between pesticide use and hemoglobin levels. This study is a descriptive study to find the correlation between paraquat pesticide exposure and hemoglobin levels. Quota sampling technique was used to collect 51 samples. Data were collected through interviews, observation of the use of Personal Protective Equipment (PPE), and measurement of hemoglobin levels by laboratory methods on 51 workers exposed to paraquat pesticide. The Chi-Square test was used to analyze the relationship between the use of PPE and the level of pesticide poisoning as measured by hemoglobin levels. The results showed that incomplete use of PPE was associated with a decrease in workers' hemoglobin levels. As many as 40% of workers who did not use PPE experienced a significant decrease in hemoglobin levels compared to workers who used complete PPE. The calculated Chi-Square value is 6.45 with a p value = 0.011 (p < 0.05) which indicates a significant relationship between the use of PPE and hemoglobin levels in sugarcane plantation workers. Based on these results, it can be concluded that proper use of PPE can reduce the risk of pesticide poisoning and maintain hemoglobin levels at normal levels.

Abstract

This research aims to synthesize chitosan-graphene oxide (chitosan-GO) material using the hydrothermal method at varying material ratios and adsorption studies on Congo red. Chitosan-GO composites were synthesized with mass ratios of (1:1), (1:3) and (1:5). The synthesized chitosan-GO composite was applied to absorb Congo red dye. The adsorption process is carried out by varying pH, contact time, concentration and temperature. The chitosan-GO composite was characterized using XRD, BET and SEM-EDS. The results of XRD characterization of the chitosan-GO composite with a ratio of 1:1 showed a diffractogram of 2θ = 22.3°, at a ratio of 1:3 the diffractogram angle was 2θ = 22.1°, while the ratio (1:5) of the diffractogram peak obtained was 2θ = 22.8°. The surface area obtained in chitosan-GO composite was 11.60 m2/g. The morphology of the chitosan-GO composite (1:5) is in the form of crystalline lumps with the constituent elements C (65.98%), O (32.68%), Na (0.22%) and S (0.09%). Adsorption of Congo red dye using chitosan-GO composite obtained optimum conditions at pH 7, contact time 50 minutes, Congo red concentration 45 mg/L and temperature 50°C. The adsorption isotherm is in accordance with the Langmuir isotherm model and the maximum adsorption capacity (Qm) is 10.245 mg/g.
