“…Meanwhile, a higher pH was obtained by Treatment 2, which might be due to the high composition of alkaline RHA. The presence of RHA in compost can ameliorate the acidity of compost; this finding has been proven by Yin et al (2022). Eventually, the pH of both treatments reached close to a neutral level from day 45 onwards.…”

Rice husk ash (RHA), palm oil mill effluent (POME) sludge, and decanter cake can be utilized as compost to reduce environmental pollution. This research attempted to investigate the effect of RHA addition to palm oil-based compost in boosting the nitrogen (N) uptake and the growth of Brassica oleracea var. <i>alboglabra</i> L. (Chinese kale plant). Two categories of compost treatment were prepared in this study: Treatment 1 (control) and Treatment 2 [consisting of 10% (wt/wt) of RHA]. Both treatments were composted for 60 days until it was matured. The temperature and pH of the composts were recorded daily throughout the study. The treatments were analyzed for moisture, water-holding capacity, and nutrient content. The Chinese kale plant was grown in growing media and applied with Treatment 1 and Treatment 2 composts. The progress of plant growth was tracked every week. Based on the analysis, Treatment 2 exhibited a higher temperature and pH profile than Treatment 1. Meanwhile, the contents of N, P, and K were higher in Treatment 1 compost. However, Treatment 2 compost had higher silicon (Si) content, moisture content, and water-holding capacity. Based on the field test study carried out on the Chinese kale plant, the N uptake, and the growth of the plant, were found to be significantly higher when applied with Treatment 2 compost compared to Treatment 1 by 19% to 31% and 13% to 53%, respectively. It was proven that the addition of 10% RHA managed to provide an adequate amount of Si, moisture content, and water-holding capacity in Treatment 2 compost that can enhance the N uptake and improve the growth of the Chinese kale plant in this study.

“…2(a-b)), which may be attributed to Al content, Fe, Ca in alkaline substances of red mud and fly ash [15]. At treatment group 5, the pH is the lowest, which may be attributed to the neutralization of potassium (K), phosphorus (P), calcium (Ca), magnesium (Mg), silicon (Si) in rice husk ash (RHA) and dried sludge [16]. In addition, the pH value of the system reduces by FeSO 4 .…”

To explore the feasibility of reusing solid waste to stabilize high-content arsenic (As) and antimony (Sb) tailings, red mud, fly ash, dried sludge, ferrous sulfate (FeSO 4 ), and rice husk ash (RHA) were used as the stabilizer to stabilize the Sb tailings in Qing Long and Du Shan. The combined treatment with 5% red mud, 10% fly ash, 5% dried sludge, 1% FeSO 4 , and 1% rice husk ash had the best stabilization effects on As and Sb, the leaching concentrations of As and Sb decreased considerably under neutral conditions, this indicates that the leaching behavior of As and Sb is controlled by the alkaline and acid-retarding capacity of the materials. In addition, the leaching of heavy metals decreases with the formation of (C-S-H) and calcite (CaCO 3 ), indicating that heavy metals exist in the form of metal hydration or hydroxide and precipitate on the surface of calcium silicate hydrate (C-S-H) and calcite particles. Leaching of heavy metals in stabilized materials can be considered as a pH-dependent and control process of stabilization products.

“…Serapan hara yang baik diduga dipengaruhi oleh kondisi tanah yang lebih baik setelah diberikan abu sekam. Yin et al (2022) melaporkan peningkatan pertumbuhan tanaman kapas dengan perbaikan tanah berstatus masam dengan aplikasi abu sekam. Abu sekam padi mengandung unsur Silikon yang lebih dari 87% (Suryana et al, 2018) dan sangat berperan dalam pembentukan dan meningkatkan lignin pada batang tanaman (Ma et al, 2001).…”

Minat konsumsi masyarakat di Kalimantan Selatan terhadap Cabai Besar (Capsicum annuum L.) sangat tinggi, namun produksinya masih rendah dan menurun di tahun 2021 dibandingkan 2020. Faktor kemasaman tanah menjadi sebab rendahnya hasil tersebut karena tanah dalam kondisi pelapukan yang lanjut. Sekam padi menjadi material organik berlimpah yang biasa digunakan petani, namun pemanfaatannya belum tepat guna dari sisi bentuk sekam padi yang diaplikasikan, sebab secara empiris belum terbukti memperbaiki tanah mineral rawa sehingga meningkatkan produski tanaman Cabai Besar. Oleh karena itu, penelitian ini bertujuan untuk menetapkan bentuk yang tepat dalam mengaplikasikan sekam padi sehingga pertumbuhan dan produksi Cabai Besar di tanah mineral rawa dapat meningkat. Penelitian ini dilakukan menggunakan desain rancangan acak kelompok satu faktor yakni bentuk sekam padi yang diaplikasikan yaitu, P0 (kontrol); P1 (sekam mentah); P2 (arang sekam); P3 (abu sekam) dengan takaran 250 g per polibag dengan tanah seberat 3 kg. Hasil penelitian menunjukkan bahwa pemberian abu sekam padi dapat meningkatkan pertumbuhan Cabai Besar dibandingkan perlakuan arang sekam padi maupun sekam padi mentah, namun produksi terbaik pada aplikasi arang sekam. Dari hasil penelitian ini, dapat direkomendasikan bahwa untuk meningkatkan hasil tanaman Cabai Besar yang dibudidayakan di tanah mineral rawa dapat diberikan arang sekam padi.
