Abstract

The biodiversity or diversity of macrofauna depends on abiotic environmental factors and biotic environmental factors. Macrofauna plays a role in decomposing organic matter so that it can restore and maintain soil productivity. The study aims to determine the diversity of soil macrofauna in the Complex Agroforestry system and its effect on the decomposition of coffee litter. The research was carried out by observation of soil macrofauna and observation of litter decomposition rate using RAK which was composed of 2 factors, namely the type of agroforestry and the difference in the age of coffee plants. The results showed that the macrofauna diversity of soil in Complex Agroforestry and Simple Agroforestry was not different because the amount of shade and diversity were almost the same. The Soil Macrofauna Diversity Index showed a low category (H' < 2) with an average INP value of 40 – 48%. Biotic factors (litter production) and abiotic factors (temperature and humidity) affect the diversity of good macrofauna. A high macrofaunaa population will affect the rate of decomposition of debris where macrofauna plays a role in remodeling organic matter.

Abstract

This study aims to evaluate land suitability for enhancing the production of key crop commodities in Ngancar District, Kediri Regency, particularly pineapple, coffee, and mango. The district has high soil fertility potential due to its location at the foot of Mount Kelud. The research methods include land surveys, soil sampling at depths of 0-30 cm and 30-60 cm, and laboratory analysis to measure soil physical and chemical properties. Results indicate that the land in the study area generally falls into the marginal suitability class (S3), with the main limiting factors being soil texture dominated by sandy loam, low K₂O levels, and high rainfall that affects pineapple growth. Slope gradient is also a limiting factor for coffee and mango cultivation. Adjustments in soil management, such as timely fertilization and planting crops with strong root systems, can improve the land's suitability potential. In conclusion, although the land in Ngancar District has certain limitations, optimizing land use can enhance the productivity of key commodities, particularly through improved soil management and appropriate fertilizer use. Keywords: Crop commodities, Land Assessment, Land Degradation, Mount Kelud.

Abstract

Background: Soil contamination occurs when chemical produced by humans pollute and alter the natural conditions of the soil. Contamination caused by heavy metals is very dangerous and can cause harm to the life of organisms through the food chain.  This study aims to determine the effectiveness of biochar and Bacillus sp in reducing Cd heavy metal levels. This study used contaminated soil with Cd levels of 2.59 ppm, pH 7.52, C-organic 1.30%, and CEC 18.35 Cmol/kg. Methodology: The research method used a factorial randomized block design with 2 treatment factors, each consisting of 3 levels: the first factor is biochar dosage, comprising B0 (without biochar), B1 (biochar 20 tons/ha, and B2 (biochar 40 tons/ha) and the second factor is bacterial concentration, comprising C0 (without Bacillus sp), C1 (Bacillus concentration 105), as well as C2 (Bacillus concentration 108). Further analysis if there are different ANOVA results, the BNJ 5% Test will be performed. Findings: the results showed that the combination of biochar 40 tons/ha with bacillus 105 (B2C1) was able to reduce Cd heavy metal levels by 52% over a 4-week incubation period, in addition to reducing heavy metal levels, it also increased soil pH. Cations that are on the surface of the biochar will exchange ions with heavy metals in the soil. Carboxyl –COOH functional groups found in biochar can be released as H+ ions, forming complexes with heavy metal ions and heavy metal ions will be bind to the surface of Bacillus sp. cells containing carboxyl groups, renderingthe the heavy metals unavailable.  Contribution: this study reveals the combination of biochar and Bacillus, where biochar provides an optimal microbial habitat, thuereby increasing remediation efficiency. In addition to knowing the interaction between organic materials with heavy metals and the development of natural and sustainable remediation

Abstract

Nitrogen is a macronutrient for plants, but its availability in saline soil is a limiting factor, making it difficult to cultivate plants. This study aims to examine the effect of the combination of Azotobacter sp. and cow manure in increasing the available N of saline soil, and to obtain the best combination in increasing the growth of tomato plants in saline soil. This research was conducted in the greenhouse and laboratory of UPN "Veteran" Jawa Timur. Saline soil samples came from the Wonorejo Mangrove land, Surabaya. Azotobacter sp. isolates came from the roots of Wonorejo mangrove trees. The study used a Completely Randomized Design with 2 factors with 3 replications. First factor was addition of Azotobacter sp., consisted of A0 (no addition of Azotobacter), and A1 (addition Azotobacter at 107 CFU/mL. Second factor was cow manure (K) involved 4 levels (in ton/ha): A0 (0); K1 (20); K2 (30); K3 (40). The results of this research showed that application of Azotobacter sp. and cow manure affected the parameters of available N, EC, pH and vitamin C content, but did not affect the parameters of plant root length. Combination of Azotobacter 107 CFU/mL + 40 tons/ha of cow manure produced the best available N of 246.48 ppm. The highest vitamin C content was 36.75 mg/g in the treatment of 107 CFU/mL Azotobacter + 30 ton/ha of cow manure. Cow manure decreased soil EC and increased soil pH.
