Abstract

Land use conversion affects the water management of a watershed, leading to flooding, erosion, and sedimentation. Tallo Watershed located in South Sulawesi is considered critical due to frequent flooding. This study aims to change the land use of the Tallo River Watershed (DAS) and its influence on watershed performance in terms of water management aspects. The methods used include spatial analysis with supervised classification to examine land cover changes and the Ministry of Forestry Regulation No. P61 of 2014 for water management evaluation. The largest land use conversion occurred in paddy fields, which decreased by 3,731.37 hectares, shrubs decreased by 1,484.87 hectares, mixed dryland agriculture by 1,017.29 hectares, water bodies by 317.60 hectares, mangrove forests by 218.27 hectares, and swamp shrubs by 26.99 hectares. These areas were converted into settlements covering 4,348.42 hectares, dryland agriculture 2,070.95 hectares, plantation forests 155.63 hectares, secondary dryland forests 34.01 hectares, airports 93.80 hectares, fish ponds 68.16 hectares, open land 19.16 hectares, and savannas 6.25 hectares. From the water management aspect, Flow Regime Coefficient value was >110, classified as very high, Annual Flow Coefficient was >0.5, also very high; sediment load and flooding were categorized as very high, and Water Usage Index value was <1700, categorized as very poor. As a result, the water management of the Tallo Watershed is classified as very poor, with a score of >130. The water management carrying capacity of Tallo Watershed falls into very poor classification from 2003 to 2022, mainly due to land use conversion and forest area covering only 11% of the total Tallo Watershed area.

Abstract

Technological developments in the agricultural sector are currently increasing for maximum production results. This encourages the use of chemicals or inorganic materials as nutrients for plants, especially mustard greens. Biosaka is a new form of innovation that is suitable for development because the basic materials used come from organic materials or green plants. This biosaka acts as an elicitor, not a fertilizer. This research aims to determine the effect of Biosaka and Gamal Leaves on the growth of mustard greens and is expected to reduce the use of chemicals. This research is divided into five main stages, namely: 1) Making Biosaka; 2) Incubation of Gamal Leaves; 3) Planting and maintaining mustard plants; 4) Application of Biosaka; and 5) Analyze and process data using a Completely Randomized Design (CRD) with 10 levels of treatment combinations (biosaka 4 levels of treatment and gamal leaves 3 levels of treatment). In the parameters of plant height, number of leaves, pH, C-Organic, and N-total, the K2G1 treatment (3 ml of biosaka + 2 liters of H2O + 25 grams of gamal leaves) was the treatment with the best results. Meanwhile, for the parameters of fresh weight, leaf length and Cation Exchange Capacity (CEC), the K3G2 treatment (4.5 ml of biosaka + 2 liters of H2O + 50 grams of gamal leaves) showed the best treatment. The K3G2 treatment was the treatment with the best results with a value of 35.67 grams with a percentage increase of 2.32% from the control treatment. Based on the results of research on the application of Biosaka and Gamal Leaves, it shows a very real influence in the interaction test of the two factors, which means there is an influence on the plants after being treated.

Abstract

This study aims to determine the diversity of soil fauna based on the landscape and soil depth in the cocoa plantation in Parenring Village, Lilirilau District, Soppeng Regency. This research was conducted from October 2020 to January 2021 located on a cocoa plantation in Parenring Village, Lilirilau District, Soppeng Regency. This research was conducted by taking soil samples using the Systematic Sampling (SYS) method, using monolithic soil sampling and disturbed soil samples. The observation of soil biota, hand sorting and microscopy were used. Based on the research results, soil samples in the back area had the highest soil biota diversity (H' = 1.32), followed by the valley area (H' = 1.29) and the middle area (H' = 1.18). Soil biota diversity is included in the medium criteria.

Abstract

Background. Edamame soybeans are a type of soybean with larger pods than common soybeans and contain a relatively high nutritional value. Nitrogen availability is a key factor in determining the productivity of edamame soybean (Glycine max (L.) Merill.), and the application of Rhizobium is one of the effective methods to enhance biological nitrogen fixation. Objective. This study aimed to evaluate the effect of various Rhizobium doses on the productivity of edamame soybean plants. Method. The experiment was conducted at the experimental field of the Soil Research Institute from August to October 2025 using a one-factor randomized block design (RBD) with four Rhizobium dose levels: no inoculation, 7.5 g/kg seed, 15 g/kg seed, and 22.5 g/kg seed, each replicated three times. Local edamame soybean seeds were incubated with Rhizobium according to the treatment dose prior to planting. Observations included root nodule distribution, nodule size, nodule color, number of leaves, plant height, flowering time, and fresh pod weight per plot. Results. Initial soil analysis indicated acidic conditions (pH 5.0–5.5) with low nutrient content. After treatment, all soil chemical parameters improved, with soil pH increasing to 6.15–6.67, organic C to 1.61–1.90%, total N up to 0.29%, available P₂O₅ up to 16.48 ppm, cation exchange capacity (CEC) up to 23.96 cmol(+)/kg, and increases in Ca, Mg, Na, and K cations. The 22.5 g/kg seed Rhizobium treatment (I3) tended to produce the highest plant growth (33.2 cm height and 27.8 leaves) and the highest soil pH, organic C, and P₂O₅ values, although the differences were not statistically significant for all growth and yield parameters. Conclusion. Analysis of variance showed that the Effect of Various Rhizobium Doses had no significant effect on all treatments. Root nodule distribution and color parameters indicated that nitrogen fixation was not occurring effectively.
