Abstract

Jagung adalah tanaman yang sangat akrab dengan petani di Sulawesi Tenggara. Komoditas ini merupakan salah satu bahan pangan andalan masyarakat Sulawesi Tenggara. Pupuk hayati Azospirilium mampu meningkatkan hasil panen tanaman pada berbagai jenis tanah maupun wilayah iklim yang berbeda. Azospirilium mendorong pertumbuhan tanaman, terutama merangsang perkembangan akar yang menyebabkan bertambahnya sistem perakaran, yaitu memperbesar dan memperpanjang jumlah akar dan rambut-rambut akar. Penelitian ini disusun berdasarkan rancangan acak lengkap (RAL) pola faktorial dengan 2 faktor, faktor pertama adalah strain Azospirillium, faktor kedua adalah dosis pemupukan dengan 3 taraf sehingga total perlakuan sebanyak 36 pot perlakuan. Pemberian urea (0,75 g) dengan Azospirillium (12,5 ml) berpengaruh nyata terhadap tinggi tanaman jagung, jumlah daun, berat segar, berat kering dan serapan N tanaman jagung dibandingkan dengan perlakuan pupuk Urea tanpa Azospirillium sp. Azospirillium (di inokulasii dari tanaman murbei) berpengaruh nyata terhadap tinggi tanaman, jumlah daun, berat segar, berat kering dan serapan N tanaman jagung, dibandingkan dengan Azospirillium dari strain lain

Abstract

Local Micro Organism Solution (LMO Solution) is a fermentation solution made from various locally available resources, both plants and animals. The LMO solution contains micro and macronutrients and bacteria that have the potential to decompose organic matter in the soil, stimulate plant growth, and act as a pest and plant disease control agent. It is easy to obtain and makes it possible to increase farmers’ desire to process agricultural waste. This research aims to determine the quality of organic fertilizer from livestock manure by utilizing local microorganisms (LMO) in cassava. This research was carried out from March 2023 to December 2023. The research was carried out at the Soil Laboratory of Hasanuddin University and the Greenhouse of the Faculty of Agriculture and Forestry, West Sulawesi University. The experimental design used in this planting test was a Completely Randomized Design (CRD), consisting of four LMO dose treatments, with each treatment carried out three times. The results of the research showed that the planting media provided by LMO tapai cassava had a significant effect on increasing the availability of the nutrients Nitrogen (N) and Phosphorus (P). The treatment regimen involving a dose of 240 ml (M3) showed the highest average values ​​for nutrient content, specifically 0.25% for Nitrogen (N) and 13.75 ppm for Phosphorus (P2O5). Providing cassava tapai LMO in the planting medium had a significant effect on the average height of spinach plants at the observation time of 10 day after planting (DAT) and the average leaf weight. The M3 treatment showed the highest average value of plant height at 10 DAT of 7.17 cm and leaf weight of 0.73 g.

Abstract

Coastal land is identical to marginal land, namely having a low soil fertility level. Liquid organic fertilizer (LOF) made from leachate can be used to increase the availability of nutrients in the soil. This study focuses on increasing the growth and yield of cayenne pepper plants on marginal land using various doses of liquid organik fertilizer made from leachate. This study was conducted from May to September 2023. The treatment was the provision of LOF consisting of 4, namely without LOF, 20%, 40%, and 60%. The results of the study showed that the liquid organic fertilizer treatment was able to increase nutrients in the soil. Treatment without liquid organic fertilizer and 60% liquid organik fertilizer significantly affected plant height. Meanwhile, the treatment without liquid organic fertilizer and 20% liquid organic fertilizer was significant for stem diameter, number of fruits, and fruit weight of cayenne pepper plants. The 20% liquid organik fertilizer treatment is recommended to increase the growth and yield of cayenne pepper plants.

Abstract

In order to achieve optimal production, oil palm plants necessitate adequate conditions that are in balance with the intended growth requirements and the land conditions of the environment in which these plants are grown. This study aims to determine the land suitability classfication and \limiting factors for oil palm plants in the Politani Samarinda oil palm experimental plantation. This study uses a quantitative descriptive methoddology based on in field observations and literature reviews. Data obtained from field observations and literature reviews is classified depending on land characteristics. The data grouping resulted are tabulated and compared with the growth growing requirements for oil palm plants. According to the results of the semi-detailed land suitability analysis for oil palm plants in the Politani Samarinda oil palm experimental plantation. The Politani Samarinda oil palm experimental plantation has limited land suitability (S3) with soil depth as the limiting factor of rooting media (rc).

Abstract

A sensitivity analysis of SWAT parameters was conducted on different spatial resolutions. The sensitivity analysis aimed to determine the input parameters that have the most impact on the of output of the model. Resolution of different inputs in the SWAT analysis can produce different input parameters that can affect the output. The purpose of this study was to identify the level of sensitivity of the parameters used in the SWAT model simulated on two different resolutions, i.e. 1: 100,000 and 1: 250,000. A sensitivity test was conducted manually using the absolute sensitivity method, i.e. a method to test the sensitivity of the parameters of SWAT model that can change (either increase or decrease) one by one while the other parameters are constant. The results show that the Nash-Sutcliffe Efficiency (NSE) coefficients derived after calibration of the SWAT models on both resolutions of maps indicate similar performance of the models, with the category for the daily simulation of excellent (NSE coefficients of 0.55 and 0.54), while the monthly simulation is categorized as very satisfactory (NSE coefficients of 0.80 and 0.82). The sensitive parameters of the SWAT model identified in the current study include CN2 (initial SCS runoff curve number for moisture condition II), Alpha_BNK (flow recession constant or recession proportional to the banks of the river), CH_K2 (effective hydraulic conductivity in main channel alluvium), CH_N2 (Manning’s “n” value for the main channel), ESCO (soil evaporation compensation factor), GW_Delay (groundwater delay), and GW_Revap (groundwater “revap” coefficient).

Abstract

Soil fertility degradation and limited access to sustainable inputs pose major constraints in marginal agricultural lands. Organic waste leachate, although rich in nutrients, often contains phytotoxic compounds that limit its direct application as fertilizer. This study evaluated the effect of leachate-based liquid organic fertilizer (LOF) on soil fertility and the growth response of chili pepper (Capsicum frutescens) in marginal soils amended with biochar. Four treatments were tested: no LOF, 20% LOF, 40% LOF, and 60% LOF. Soil analysis showed that LOF application improved pH, organic carbon, and macronutrient content (N, P,K), with the highest pH in the 20% LOF treatment and the highest C-organic in the 60% LOF treatment. However, the best plant growth was observed in the control treatment, possibly indicating inhibitory effects of phytotoxic compounds such as phenols and organic acids present in the LOF. Although 20% LOF resulted in the highest fruit weight, differences among treatments were not statistically significant. These results suggest that while leachate-based LOF enhances soil quality, its high concentration may hinder plant growth. The findings support the potential use of leachate as a low-cost nutrient source for sustainable agriculture, provided that proper detoxification and formulation strategies are applied.
