Abstract

Pests and diseases of maize plants have the potential to cause crop failure. Lack of information and knowledge about plant pests and diseases and limited field extension workers lead to errors in diagnosing maize pests and diseases. This results in inappropriate crop management that decreases production. Therefore, farmers need a tool to detect pest and disease attacks through physical symptoms seen on plants in the field. This research aims to produce an Agricultural Information System, namely an android-based expert system to detect pests and diseases in corn plants. The method used is software with prototyping to get an overview of the application to be built through a prototype application design and then evaluated by the user. The research stages include; gathering needs, building prototypes, evaluating protoype, coding the system, testing the system, evaluating the system, and using the system.  The result is the symptoms of pest and disease attacks on corn plants in the field, can be detected through the form of symptoms that are matched with images and characteristics of symptoms displayed on the Agricultural Information System software installed on android-based mobile phones or Tablets. Test results from 28 respondents showed that the success rate of detection of pest symptoms on corn plants was 75%, and for disease symptoms was 90%.

Abstract

This research was conducted in Wanggarasi Sub-district, Pohuwato Regency, Gorontalo Province, specifically in Bohusami Village and Bukit Harapan Village. The objectives of this study were (1). To analyze the biophysical land conditions (land capability, land suitability, land carrying capacity, production), as well as the social conditions of the community, particularly population pressure, which can support a sustainable maize land-use system. (2). To develop an appropriate model for optimizing sustainable maize cultivation in Wanggarasi Sub-district, Pohuwato Regency, Gorontalo Province. The method used was land evaluation with a land unit approach. Sampling locations were determined using stratified random sampling, considering land units at the study sites—namely, slope, landform, and land use. The preparation of land capability maps, land suitability maps, and land optimization maps was carried out through interpretation of RBI maps, administrative maps, land unit maps, and LCLP analysis results. Meanwhile, maps of land carrying capacity, population pressure, and production were developed based on RBI maps, administrative maps, and secondary data. Data analysis was conducted using ecological spatial analysis with Geographic Information System (GIS) and supporting socio-economic data were analyzed descriptively. The research results showed that the study area is dominated by land with low optimization categories (R), expressed through the functional formula: OPT (R) = f (KL (III, IV) + KS (S3, N1) + DDL(R) + P(R) + TP(R)). The models and strategies for optimizing land in the low category (R) can be implemented through: (1) Identifying land units combining dry fields and rainfed areas that ensure the availability of land with high (T) or moderate (S) optimization categories, with a minimum area approximately equal to that of land units categorized as moderate or low in the sub-district. (2) Identifying land-use combinations that can yield production categorized as high (T) or moderate (S) land optimization by converting part of the coconut plantation area—particularly those needing replanting—into dryland maize cultivation. Additionally, seeking land-use combinations that ensure the availability of land areas with moderate optimization category (S), such as mixed gardens and dry fields.

Abstract

This study aims to analyze variations in soil physical properties and their implications for corn (Zea mays L.) land management strategies in Pulubala District. This study used a quantitative descriptive survey method on three systematically selected corn land units, with soil sampling at a depth of 0-20 cm for analysis of texture, water content, bulk density, particle density, and porosity in the laboratory. The results showed that points 1 and 3 have a sandy loam texture with a dominant sand content, while point 2 has a clay texture with a dominant clay fraction. The bulk density and porosity values ​​​​illustrate the gradation of soil compaction, where point 1 is relatively looser with high porosity, while points 2 and 3 show lower porosity and indications of compaction that inhibits aeration and root penetration. In terms of management, land with good physical conditions needs to focus on maintaining soil structure, while more compacted land requires intervention in the form of adding organic matter, improving aeration, and regulating drainage to maintain an optimal corn growing environment.

Abstract

Land use change and population growth are the main factors influencing the sustainability of land resource management, particularly in areas experiencing rapid development dynamics. This study aims to analyze the condition and changes in land carrying capacity in Wanggarasi Sub-district using a spatial and temporal analysis approach based on Geographic Information Systems (GIS). The research employs a descriptive quantitative method utilizing secondary data, including population data, land use data, and multi-temporal satellite imagery. The land carrying capacity index was calculated based on several indicators, namely the proportion of the farming population, the area of cultivated agricultural land, farmer involvement in non-agricultural activities, and the availability of land suitable for living. The results indicate that Wanggarasi Sub-district falls into the category of moderate land carrying capacity, with indications of imbalance between the high proportion of the farming population and the limited availability of productive agricultural land and land suitable for living. This condition reflects the presence of socio-ecological pressures that may increase the risk of land carrying capacity deficits if not accompanied by adaptive land management policies. Spatial analysis demonstrates that GIS is effective in identifying the spatial distribution and zoning of land carrying capacity in greater detail. This study is expected to serve as a basis for spatial planning and evidence-based policymaking to support sustainable regional development at the sub-district level.

Abstract

Maize (Zea mays L.) is a significant food commodity in Telaga Biru Subdistrict, Gorontalo Regency; therefore, information on soil fertility is crucial as a basis for effective land management. This study aims to analyze the chemical and physical fertility of soils in maize cultivation areas and to identify efforts to improve maize productivity in Telaga Biru Subdistrict. The study was conducted from April to November 2025 in Telaga Biru Subdistrict, Gorontalo Regency. A descriptive quantitative method with a land unit-based survey approach was employed. Soil sampling was conducted diagonally in three villages: Timuato, Modelidu, and Talumelito, at a depth of 0-20 cm. The analyzed chemical fertility parameters included soil pH, nitrogen, organic carbon, cation exchange capacity, available phosphorus, potassium, and base saturation. Physical soil properties analyzed included soil texture, bulk density, and soil color. The findings showed that the soil pH was slightly acidic, with nitrogen and organic carbon contents falling into the low to moderate categories. The cation exchange capacity and the availability of phosphorus and potassium were moderate, while base saturation was relatively low: The physical soil properties were dominated by clay to clay loam textures with relatively high bulk density values. These conditions indicate that maize cultivation land in Telaga Biru Subdistrict has sufficient fertility to support plant growth; however, appropriate soil management is still required through balanced fertilization, the addition of organic matter, and improvement of soil physical properties to enhance productivity sustainably.
