Abstract

The intensive use of fossil fuels has led to a significant increase in air pollution, which negatively affects human health and the environment. Fly ash (FA), a byproduct of coal combustion, has great potential as an adsorbent for hazardous gas pollutants due to its physical and chemical properties. This research aims to evaluate the effectiveness of fly ash as an adsorbent in reducing gas pollutants such as CO2, SO2, and NO2, as well as to examine the influence of temperature and material characteristics on adsorption capacity. The results indicate that the maximum adsorption capacity for each gas pollutant is achieved at different temperatures, fly ash demonstrating the highest performance at 150 °C for CO2 adsorption, achieving an efficiency of 94.7%. For SO2 and NO2, the optimum temperatures are 200 °C, with efficiencies of 72.17% and 100%, respectively. This study also emphasizes the importance of selecting the appropriate characteristics of the adsorbent material to enhance adsorption efficiency. This finding has the potential to support the development of more efficient and sustainable air pollution reduction technologies in the future, by utilizing industrial waste such as fly ash as an innovative solution.

Abstract

The utilization of coal combustion waste, specifically fly ash and bottom ash, as a soil amendment offers an opportunity to enhance the fertility of peat soils in East Kalimantan, which typically have low levels of essential nutrients such as nitrogen (N), phosphorus (P), and potassium (K). This study aims to evaluate the impact of adding coal ash on peat soil's chemical composition and quality as a growing medium. The chemical composition analyzed includes alumina (Al₂O₃), silica (SiO₂), phosphorous anhydride (P₂O₅), iron(III) oxide (Fe₂O₃), and calcium oxide (CaO). X-ray Fluorescence (XRF) was used to determine changes in nutrient content. The results indicate that adding coal ash increases the levels of potassium (K) and silica (SiO₂), but decreases the levels of nitrogen (N) and phosphorus (P₂O₅). Additionally, adding coal ash affects soil pH, which impacts nutrient availability. These findings indicate that while coal ash can enhance soil enrichment with potassium and silica, its impact on nitrogen, and phosphorus must be carefully managed to optimize fertilization and promote healthy plant growth.

Abstract

Biomass is a renewable energy source that can be processed into charcoal through a carbonisation process, which depends on temperature to improve the quality of the charcoal produced.  This research focuses on the utilisation of Oil Palm Fronds (OPF) and Palm Kernel Shells (PKS) as biomass feedstock in an effort to produce an alternative fuel that can be used in the co-firing process with Low Rank Coal (LRC). This study heats palm fronds and shells at 300°C to 600°C, then measures moisture content, ash content, calorific value, and sulfur content. Based on the results, a temperature of 600°C was identified as the optimal condition for the OPF and PKS drying process. At this temperature, a significant decrease in moisture content is directly proportional to the increase in ash content and calorific value, indicating an improvement in fuel quality. The highest calorific values achieved were 6095.35 kcal/kg for OPF and 7364.81 kcal/kg for PKS. In addition, the sulphur content of the charred biomass is much lower than that of coal, which provides an advantage in terms of cleaner emissions. In comparison with LRC, the charred biomass showed better quality in terms of calorific value and lower sulphur content, despite the higher ash content of the biomass. OPF and PKS that have undergone the charring process offer a more environmentally friendly fuel alternative and have the potential to replace LRC in combustion applications, resulting in lower emissions. This study thus reinforces the potential of oil palm biomass as a promising renewable energy source.

Abstract

Oil Palm (Elaeis guineensis Jacq.) is a crucial plantation commodity in Indonesia's economy. The increasing global demand for oil palm has driven the expansion of oil palm plantations. However, this expansion is often constrained by limited fertile land. Fly ash, a byproduct of coal combustion, contains essential nutrients such as calcium, magnesium, and silica. Several studies suggest that fly ash potentially improves soil physical and chemical properties, as well as enhance nutrient availability for plants. This research aims to evaluate the effectiveness of adding fly ash in various growing media, dolomite, and organic fertilizers on the growth of oil palm seedlings. The study employs a Completely Randomized Design (CRD) with several treatment combinations, including fly ash, organic fertilizer, dolomite, and NPK 16:16:16 fertilizer doses. The results indicate that combining fly ash and organic fertilizer is the best choice for improving oil palm seedling growth. Additionally, adding NPK 16:16:16 fertilizer at 36 grams per polybag yields excellent growth results. Interaction analysis indicates significant effects of these combinations on seedling growth improvement. This preliminary study is expected to provide foundational information useful for further research on utilizing fly ash and other organic materials in oil palm cultivation and the potential application of this technology on a larger scale.

Abstract

Pertumbuhan industri tekstil yang pesat telah menyebabkan peningkatan limbah cair yang mengandung zat pewarna sintetis. Zat pewarna ini dikenal sulit terurai serta berdampak negatif terhadap lingkungan dan kesehatan manusia. Berbagai metode pengolahan limbah telah dikembangkan, salah satunya adalah metode adsorpsi yang dinilai efisien dan ramah lingkungan. FABA yang merupakan limbah padat dari Pembangkit Listrik Tenaga Uap (PLTU), kini tidak lagi dikategorikan sebagai limbah B3 dan berpotensi dimanfaatkan sebagai material adsorben. Artikel ini mengkaji karakteristik FABA, efektivitasnya dalam mengadsorpsi zat pewarna, serta faktor-faktor yang memengaruhi kinerjanya. Hasil kajian menunjukkan bahwa FABA mampu menurunkan konsentrasi zat pewarna seperti Rhodamine B (RhB), Direct Blue 78 (DB 78), Crystal Violet (CV), dan Direct Fast Scarlet 4BS (DFC 4BS) secara signifikan, dengan efisiensi penyisihan mencapai lebih dari 90%. Pemanfaatan FABA sebagai adsorben tidak hanya menawarkan solusi pengolahan limbah cair industri yang lebih ekonomis dan berkelanjutan, tetapi juga berkontribusi terhadap pengurangan limbah padat PLTU. Kajian ini diharapkan dapat menjadi referensi dalam pengembangan teknologi pengolahan limbah industri yang lebih ramah lingkungan di masa depan.

Abstract

Grape (Vitis vinifera) cultivation is hampered by a lack of suitable land and challenging nurseries. Use of crimson yellow podzolic soil for vine cuttings can be suboptimal. Although podzolic soil has a low capacity to absorb macro- and micronutrients and an acidic pH, it can nevertheless be used as a growing medium. A synthetic growth regulator (ZPT) bath of naphthalene acetic acid (NAA) needs to be added to the local red master grape variety, which has started to develop as a scion in nurseries. In order to assess the impacts of NAA-soaked concentrations on podzolic soil media and identify the morphological traits of local Red Master grape cuttings, this study set out to identify these traits. Its goal was to find out how auxin affected the development and yield of grapes (Vitis vinifera L.) grown in red yellow podzolic soil. A non-factorial totally randomized design with one factor (NAA concentration) was used in the study, with a block of 4 treatments and 3 repetitions. The varied NAA concentrations used in the treatment procedure included F0 (0 g L-1), F1 (2 g L-1), F2 (4 g L-1), and F3 (6 g L-1). The variables that were observed included the number of shoot bursts, the timing of leaf emergence, the number of sheet leaves, the length of the tendrils, and the proportion of live cuttings. ANOVA was used to tabulate and analyze observational data at a 5% level, and DMRT analysis was used to continue the analysis at the same level. According to the results, soaked NAA at a concentration of 0 g L-1 (S0) as the control treatment had the best results for the variable number of shoots and leaves, while a concentration of 2 g L-1 (S1) had the best results for the variable length of tendrils. However, soaked NAA had no significant impact on the variable when leaves emerged. Soaking auxin at the bottom of cuttings had no effect on shoot formation. Reduction of auxin due to defoliation can result in the expression of the isopentenyl-transferase (IPT) gene. Auxins, such as Indole-3-acetic acid (NAA), are usually involved in the regulation of root and leaf growth. If a plant has many leaves and few roots without the use of additional NAA or auxin, several factors may play a role, such as plant genetics, environmental conditions, and environmental stress. The use of additional NAA or auxin can explicitly affect the growth of roots and leaves. The survival percentage of cuttings is still low because it is influenced by the quality (material) of the cuttings, the age of the parent tree, growing media and water availability.

Abstract

Coal ash, stemming from the combustion process in power plants, emerges as a potential pollution source due to its metal content. Recognized for housing various metals with environmental contamination potential, this study meticulously delves into the metal analysis of chromium (Cr) and lead (Pb) within four distinct samples of fly ash (FA) and bottom ash (BA) sourced from diverse coal-fired power plants across Indonesia. Employing the batch leaching method, the coal ash samples (FABA) underwent a 6-hour immersion in deionized water, replicating environmental scenarios akin to rainwater interaction with coal ash at disposal sites. XRF analysis scrutinized the chemical composition of each sample, while the leaching filtrate underwent analysis via pH meter and AAS to ascertain pH values and the concentrations of Pb and Cr. Results unveiled a substantial pH variation in the leachate, fluctuating from the initial deionized water pH of 7.00 to a range between 6.86 and 9.18. Notably, subsequent leaching indicated undetectable concentrations of Pb in all samples, with most exhibiting low Cr concentrations post-leaching, except for FA-2, FA-4, and BA-4, which displayed modest Cr concentrations. The scarcity or low concentrations of Pb and Cr post-leaching suggest an efficacious process inhibiting heavy metal release. This study offers profound insights into the chemical intricacies of coal ash, underlining its potential environmental ramifications. The absence of detectable heavy metal concentrations post-leaching underscores a minimal risk of environmental pollution, underscoring the imperative to comprehend the chemical reactions intrinsic to the leaching process for optimal waste management strategies.

Abstract

Nilai kalori batubara sangat penting bagi batubara itu sendiri. Selain berpengaruh pada proses pembakaran, nilai kalori juga menunjukkan kandungan energi yang terkandung dalam batubara. Nilai kalori batubara dipengaruhi oleh beberapa parameter diantaranya ialah kelembapan, kadar abu, zat terbang, karbon tetap dan total sulfur. Namun 40% cadangan batubara di Indonesia masih kualitas rendah. Hal ini menunjukan perlu adanya teknologi peningkatan nilai kalori yang sesuai, dengan tujuan batubara kualitas rendah ini dapat digunakan secara maksimal serta mengurangi emissi CO2 yang dikeluarkan selama proses pembakaran di PLTU. Teknologi pengeringan batubara menjadi salah satu teknologi peningkatan nilai kalori batubara, dengan konsep pengurangan kadar air yang dipengaruhi oleh suhu dan tekanan. Teknologi ini terbagi menjadi empat kategori yaitu mekanis, evaporasi, non-evaporasi dan pirolisis. Sesuai dengan program hilirisasi kementrian ESDM tentang pemanfaatan batubara, teknologi yang dikembangkan dalam proses upgrading  batubara adalah teknologi UBC (Upgrading Brown Coal) dan teknologi CDB (coal dry briquette). Selain itu campuran batubara kualitas rendah dengan biomassa juga dimanfaatkan menjadi bahan bakar pembangkit listrik atau sering disebut co-firring. Baik diaplikasikan langsung maupun dibentuk menjadi briket. Program ini dijalankan untuk mendorong Program NZE pemerintah yang berkomitmen untuk mencapai nol emisi CO2 di tahun 2050.
