“…The basic ingredients of humic acid are organic materials (organisms and animals) that undergo physical, chemical, and biological processes through a perfect humification process which results in the oxidation polymerization of phenolic compounds, lignin, and proteins from organic materials and also derived from the metabolism of organisms [36,38]. Humic acid can stimulate and activates biological and physiological processes in living organisms due to humic acid being more of a soil conditioner [36,39]. The results showed that the humic acid content in SK fertilizer was 14.99% ± 0.08 and SM 11.69% ± 0.57.…”

Trials of making organic fertilizer using seaweed, fish silage, molasses, and a consortium of microbes were carried out. This study aimed to determine the activity of Bacillus subtilis, Pseudomonas florescent, and Trichoderma sp to produce micro and macro nutrients, humic acid, water content, and growth hormone. The organic fertilizer formula consisted of 26.6% sargassum flour, 16% fish silage, 1.8% molasses, 2.4% K. alvarezii paste; and 53.2% sargassum paste. The treatments consisted of formulated without adding microbial consortium (SK) and with adding microbial consortium (SM) as much as 10% volume per weight (v/w), then fermented for 10 days at room temperature. The balance values of growth hormone auxin (IAA), gibberellin (GA3) and cytokinins in SM treatment were the best measured at 181 ppm, 73 ppm, and 120 ppm, respectively.

“…Pemberian HA diduga berperan dalam peningkatan ketersediaan hara nitrogen (N) pada media tanam sehingga berpengaruh terhadap penambahan tinggi tanaman dan merangsang pertumbuhan akar (Lestari et al, 2020). HA mengandung unsur karbon (C) dan N yang jumlahnya masing-masing mencapai 40-80% dan 0-0,3% (Firda et al, 2016). Pada HA juga terdapat hara kalium (K), fosfat (P), kalsium (Ca), mangan (Mn) dan seng (Zn) (Tahir et al, 2011).…”

“…Hasil penelitian pada Tabel 1 menunjukkan bahwa pemberian HA memiliki pengaruh pada variabel jumlah daun dengan jumlah daun terbaik pada perlakuan P3. Unsur yang terdapat pada HA diantaranya adalah C dan N yang jumlahnya masing-masing mencapai 40-80% dan 0-0,3% (Firda et al, 2016). Selain memperbaiki sifat fisika tanah, C/N ratio yang tinggi pada HA akan mengikat kalium (K) pada media tanam sehingga hara K akan semakin banyak tersedia bagi tanaman terutama pada fase perkembangan daun hingga inisiasi pembentukan organ generatif (Hermanto et al, 2012).…”

Sugarcane (Saccharum officinarum L.) is a plantation crop that is used as raw material for the consumer sugar and industrial sugar. The need for sugar is increasing every year but is not matched by an increase in sugarcane production due to several factors including cultivation management that is not optimal. Sugarcane production begins with good nursery management, including using genetic of seeds and the right planting media. One alternative to improve the quality of growing media is to use humic acid (HA) as a soil enhancer. This study aims to determinate the effect of giving HA on the morphological characteristics of sugarcane seedlings of Bululawang variety (BL). This research was carried out in an integrated laboratory greenhouse at the Polytechnic LPP Yogyakarta from Maret to July 2021. This study used a non-factorial completely randomized design (CRD) with five treatments and three replications consisting of P0 (control), P1 (25 ml.polybag-1), P2 (50 ml.polybag-1), P3 (75 ml.polybag-1), and P4 (100 ml.polybag-1). The morphological characteristics observed is plants height (cm), number of leaves (strands), stem diameter (mm) and longest root length (cm). the results of the study were analyzed using ANOVA at the 5% level and continued using the Duncan Multiple Range Test (DMRT) at the 5% level. The result showed the effect on morphological characters on all observation variables where the P3 treatment had the best growth and morphological characters, so that in general the additional of HA affected the morphological characteristics of sugarcane seedlings of BL varieties.

There are 83 paper mills in Indonesia recorded by the Indonesian Pulp and Paper Association (APKI) spread throughout the archipelago. These paper companies produce products in the form of tissues, various types of paper, and other fiber-based products. Efforts to meet the needs of this raw material produce innovations in the form of using waste paper by separating the ink from the fibers contained in the paper, this separation process is known as the deinking process. Paper mill solid waste can be in the form of sludge, pith, and biosludge. Sludge is a factory solid waste originating from the settling of WWTP which consists of 90% solid and 10% liquid. Paper mill waste in the form of solid waste from sludge contains heavy metals such as Cd, Cr, Pb, Ni, Cu, and Zn. These metals can be overcome by bioremediation using guano fertilizer which is an organic material derived from bat droppings which is rich in phosphate. The purpose of this study was to determine the microbial population in soil contaminated with paper mill sludge waste treated with guano fertilizer. The parameters observed in this study were the total number of bacteria and fungi that survive in soil contaminated with paper mill waste as an indication that the land can still be planted with certain plants. This research was conducted at the Laboratory of Soil Biology, Laboratory of Soil and Land Fertility Agrotechnopark – Faculty of Agriculture – University of Jember. This study used a 3x3 two factorial experimental design with the basic pattern of Randomized Block Design (RAK), namely between the concentration of paper mill effluent and the dose of guano fertilizer, each treatment was repeated three times. The microbial population can be determined by analyzing total bacteria, total fungi. Soil that had been contaminated with paper mill waste was incubated with guano fertilizer, each combination was analyzed at 15 hst and 30 hst for total bacterial and total fungal populations. During the incubation period, irrigation was carried out using a sprayer to maintain moisture in the incubation media. The results showed that the total population of bacteria and fungi in the growing media contaminated with paper mill sludge waste by administering different doses of guano showed results that were not significantly different, but the total population tended to increase. with increasing incubation period. Pollution of sludge waste in the planting medium has a significant effect on increasing the total Fungi Population when compared to the control. The relationship between paper mill effluent pollution and guano fertilization is very low with a coefficient of determination of less than 0.5.
