Abstract

Sustainable agriculture plays a crucial role in achieving SDG 2 (Zero Hunger), SDG 9 (Industry, Innovation and Infrastructure), and SDG 12 (Responsible Consumption and Production). One strategic approach to achieving these goals is the utilization of solid organic fertilizers derived from biowaste, which can enhance soil fertility and strengthen food security. The effectiveness of such fertilizers is highly influenced by their macro- and micronutrient content, which must comply with national quality standards. This study analyzes the levels of phosphorus (P), potassium (K), and zinc (Zn) in three samples of solid organic fertilizer (PAP 01, PAP 02, and PAP 03) based on the Indonesian National Standard (SNI) 7763:2018, along with moisture content as an indicator of product stability. Phosphorus was analyzed using UV-Vis spectrophotometry, while potassium and zinc were measured using Atomic Absorption Spectrophotometry (AAS). The results showed moisture content ranging from 5.02% to 45.24%, P?O? from 1.47% to 4.00%, K?O from 1.58% to 2.86%, and Zn at 261.22 mg/kg, with good analytical precision (RPD and RSD < 5%). These findings indicate that solid organic fertilizers meet the minimum nutrient requirements for plant growth. The application of analytical chemistry in this study not only ensures product quality but also supports applied science innovation in promoting sustainable agriculture and community empowerment through science-based development.

Abstract

This study aims to evaluate the effect of biochar-based growing media on the growth of seedlings of three tobacco (Nicotiana tabacum L.) varieties—Jinten, Paiton-2, and Perancak-95—cultivated in clay-textured soil. Clay soil poses challenges for plant growth due to poor drainage and limited aeration, which can hinder root development and nutrient absorption. To address these limitations, biochar is used as a soil amendment, known to improve soil structure, enhance water retention, and increase nutrient availability. The experiment was arranged in a factorial Randomized Complete Block Design (RCBD) with two factors: tobacco varieties and seed soaking treatments (warm water, warm water with Azotobacter, and warm water with biohumic), each replicated three times. Observed parameters included plant height, leaf dimensions, stem diameter, root length and weight, and total fresh biomass. The results are expected to identify the tobacco variety that responds best to biochar treatment and provide recommendations for optimal seedling growth in marginal soils.

Abstract

This study aims to examine the physiological characteristics of seedlings from three national tobacco varieties (Jinten, Prancak 95, and Paiton 2) grown in biochar media under varying soaking treatments. Biochar, as a planting medium, has the potential to improve seedling quality and growth by increasing water retention capacity and soil nutrient availability. Seed soaking treatments were carried out using warm water, warm water + Azotobacter, and warm water + Biohumic to stimulate seed physiology. The Research employed a factorial Randomised Block Design (RBD) with two factors: variety and type of soaking, each repeated three times. The observed physiological parameters included the number of leaves, leaf length, plant height, leaf area, leaf colour, leaf area index, and total chlorophyll content, chlorophyll a, and chlorophyll b. The results showed that the combination of tobacco variety and soaking treatment significantly affected the physiological parameters of tobacco seedlings, both in vegetative growth and internal physiological content. The Prancak-95 variety (A2), treated with warm water + Azotobacter (D2), showed the best physiological performance in terms of plant height and leaf area. Meanwhile, the Jinten variety (A3) under the same soaking treatment showed the best leaf colour quality. In addition, the Paiton-2 variety (A1) with warm water soaking (D1) had the highest chlorophyll a content, indicating high photosynthetic activity. The combination of biochar media and biological soaking treatments effectively supported optimal seedling growth, as indicated by leaf morphology and chlorophyll content. This indicates that selecting superior varieties and appropriate soaking techniques plays a crucial role in enhancing seedling physiological efficiency and ensuring the success of sustainable tobacco cultivation.

Abstract

This study aims to evaluate the effectiveness of bioremediation using bio-fertilizers on the early growth of corn (Zea mays L.) in soil from former nickel mining sites. The study was conducted by observing soil characteristics and plant growth parameters, including soil texture, moisture content, cation exchange capacity (CEC), and macro nutrient content (N, P?O?, and K?O). Treatment L4P1 (location Sorowako with PGPR application) showed the best physical and chemical results, with the highest CEC value (40.65 cmol(+)/kg) and balanced macro nutrient content. Corn plant growth also showed a positive response to this treatment, indicated by the number of leaves (4.67), plant height (39.70 cm), leaf length (29.51 cm), as well as higher dry and wet weights compared to other treatments. Treatment P1 generally provided the most consistent and superior results compared to P2 and P3, demonstrating the effectiveness of the microbial formula in improving soil quality. degraded. In contrast, the L5 treatment showed the lowest results on almost all parameters. These results indicate that bioremediation with biofertilizers, particularly using PGPR (P1), has great potential in reclaiming former nickel mining soils and supporting food crop productivity on marginal lands

Abstract

Local tobacco has an important role in the kretek cigarette industry in Indonesia, because 80% of kretek cigarettes are made using local tobacco. However, in some areas, the quality of local tobacco remains low due to inefficient fertilisation. Using slow-release fertiliser can increase the efficiency of nutrient uptake by plants. This Research aims to examine the use of biochar-based slow-release fertiliser on the morphological characteristics of tobacco plants. The Research method was a field experiment using a randomised block design to test the SRFbiochar SP36 fertiliser treatment. The treatments tested were SRFbiocharSP36 as basic fertiliser, SRF-BiocharSP36, SRF-biocharSP36+Cow urine and SRF-BiocharSP36+Cow urine+Azotobacter on tobacco morphological characters, including: plant height, number of leaves, stem diameter, flag leaf angle and wet weight of tobacco leaves. The Research found that SRF-BiocharSP36, used as a basic fertiliser, produced the best results and significantly affected plant height (68.60 cm) and stem diameter (19.39 mm). Apart from that, this formula gave the best results for the number of leaves (24) and the wet weight of leaves (44.92 g).
