Abstract

Land use and land cover (LULC) changes can influence policies in a region due to economic and social conditions caused by population growth. The objective of this study is to analyze and map LULC changes in 2002, 2012, and 2022 using the Random Forest approach on Google Earth Engine, and to predict land use in 2042 using Markov-CA, thereby supporting the provision of accurate and sustainable policy data related to LULC in Banggai Islands Regency. This method can provide accurate information about the spatial distribution of rational LULC, balancing development demands with sustainable environmental protection. The study's results indicate that LULC has undergone significant changes from 2002 to 2022. There has been an increase in plantation land, open land, and settlements originating from forest and scrubland. Predictions of LULC changes in 2042 show an increase in plantations, settlements, and open land, while other land uses are declining. Effective land use policies require spatial planning that considers the potential andlimitations of land, as well as the space needs for residential, agricultural, and forest areas. This approach will facilitate the application of land conservation principles in sustainable, balanced agricultural and non-agricultural development in Banggai Islands Regency.

Abstract

Effective agricultural land use necessitates careful and intensive management that considers the unique characteristics of each plot, as these can vary significantly. Given the extensive information on land suitability for coffee plantations in the Tinangkung Selatan sub-district, research is essential to assess the area's substantial potential for coffee cultivation. The primary aim of this study is to determine the suitability of land for coffee plants in situ within the South Tinangkung District. A quantitative descriptive survey approach was employed, matching actual land conditions with coffee land suitability criteria. Analysis of eight sample points revealed three suitability classes: moderately suitable (S2), marginally suitable (S3), and unsuitable (N). At point 2, the land was classified as moderately suitable (S2) for coffee cultivation, covering 567.03 ha, influenced by moderate soil depth, base saturation, very low nitrogen levels, and a gentle slope. The marginally suitable (S3) criteria were affected by nitrogen levels (point 1), altitude (point 3), base saturation, organic carbon, and nitrogen levels (point 4), encompassing 7,898.87 ha. The unsuitable class (N) was identified at points 5, 6, 7, and 8, covering 6,098.42 ha, primarily due to altitude. Improvement efforts indicate potential land suitability, with 2,049.16 ha classified as moderately suitable (S2), 7,479.89 ha as marginally suitable (S3), and 5,035.28 ha as unsuitable (N). Engaging stakeholders, including government, research institutions, communities, and the private sector, is crucial for managing this land effectively, particularly in restoring and enhancing the function of less productive or degraded areas to optimize their potential.

Abstract

 Rice fields are a highly strategic form of land use because they are the main resource for producing rice. Rice is a crop that grows well in flooded conditions. However, above-normal flooding will also affect the condition of the rice plants themselves. Climate change, erratic rainfall and inadequate drainage infrastructure often cause prolonged flooding. Minakarya Village is one of the centres of rice (Oryza sativa L.) production in Moilong Subdistrict, Banggai Regency. Currently, the problem faced in rice paddy production is a decline in productivity due to excessive waterlogging, which causes damage to the land. Therefore, this study aims to formulate strategies for managing rice fields in Minakarya Village, Moilong. managing rice fields in Minakarya Village, Moilong Subdistrict, Banggai Regency. This study also uses the SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis method to evaluate internal and external factors that influence waterlogging problems and formulate relevant strategies. The results of this study show that the recommended strategies for overcoming waterlogging in rice fields in Minakarya Village include improving drainage, applying modern technology, and selecting rice varieties that are resistant to waterlogging.

Abstract

Maize is a key food commodity underpinning the economy of the Simpang Raya District, yet its yield has fallen to 3.6 tonnes per hectare. Imbalanced or inadequate fertilisation can lead to excessive nutrient uptake by plants, resulting in a decline in soil fertility. This study evaluates soil nutrient availability and fertility status to guide effective soil management aimed at optimising maize growth in Simpang Raya District, Banggai Regency. Using field surveys and kriging interpolation, the spatial distribution of soil nutrients was mapped, followed by comparison with soil fertility standards to determine fertility status. The methods used provided a high level of accuracy and the best estimates for determining soil fertility. Overall, this suite of methods represented a cost-effective and efficient solution for mapping soil fertility across extensive agricultural areas. The research results indicated that the study site had a soil pH of 5.6–6.2 (slightly acidic) and organic carbon (C) of 0.35–1.71%, with an average of 0.99% (very low). Phosphorus (P) content ranged from 7.51–32.01 ppm with an average of 18.09 (moderate), whilst potassium (K) ranged from 8.56–24.20 mg/100g, with an average of 16.55 (low). Cation Exchange Capacity (CEC) was classified as moderate, with an average of 20.93 cmol(+)/kg, ranging from 8.79–25.32 cmol(+)/kg, and Base Saturation (BS) averaged 32.68% (low), ranging from 14.02–58.71%. Overall, soil fertility for maize crops in the Simpang Raya District was classified as low to moderate. Management through liming and the application of organic fertiliser were strongly recommended. To improve soil quality, necessary interventions include liming, land rehabilitation, and the application of bio-fertilisers/biochar to increase organic carbon and base saturation. These measures require support in the form of organic fertiliser subsidies and intensive extension services from the government, particularly for the Simpang Raya District.

Abstract

The current understanding of food security significantly impacts agricultural policy, especially regarding the availability of food to meet local and national needs. The Banggai yam is a local carbohydrate crop in Banggai Islands Regency that plays a vital role in food diversification and security. Thanks to its high carbohydrate content, this tuber has great potential as a food reserve and an alternative to rice to support food sovereignty in Banggai Islands Regency. To cope with the increasing demand, a comprehensive development plan is needed. This research aims to develop a model of Banggai yam production and needs as a fulfilment of food availability in the Banggai Islands Regency. This research uses a dynamic system approach. The dynamic system can describe the relationship between various variables in its development. The results of the study indicate that the current level of Banggai yam production is insufficient to meet overall demand. Currently, there is a production deficit of 1,703.54 tons for Banggai yam in 2018, which is projected to decrease to 1,514.9 tons by 2042. Simulation results indicate that with a 1.2 percent increase in the planting index, a 1 percent expansion of new land, and a 4 percent increase in exports in Scenario 1, which is overall moderate, a surplus of 3.3 tons will be achieved, with production reaching 11,846.8 tons and demand at 11,843.5 tons. This scenario will meet the total demand for Banggai yam until 2042. Successful implementation depends on the involvement of various stakeholders, including the government, farmers, and businesses involved in Banggai sweet potato production, making this commodity a flagship food product in Banggai Islands Regency.

Abstract

Pertumbuhan penduduk di Kabupaten Banggai Laut pada tahun 2024, rata-rata sekitar 0,34%, harus diikuti oleh peningkatan ketersediaan pangan secara nasional. Pertanian dunia abad ke-21 akan berlangsung dalam tekanan tantangan yang terus meningkat. Salah satu penyebab utamanya adalah pertumbuhan penduduk, yang pada tahun 2025 diperkirakan akan mencapai 8,5 miliar. Dengan demikian, perlunya kajian daya dukung lahan untuk swasembada pangan. Oleh karena itu, penelitian ini menggunakan pendekatan daya dukung lahan (DDL) dan daya dukung wilayah pertanian (DDWP). Pendekatan ini yaitu membandingkan ketersediaan lahan dan keutuhan lahan yang diestimasi berdasarkan jumlah penduduk dan kebutuhan fisik minimum (KFM). Hasil penelitian diperoleh bahwa daya dukung lahan pertanian tanaman pangan Kabupaten Banggai Laut dari beberapa komoditas tanaman pangan  seperti jagung, kacang tanah, ubi jalar dan talas telah diperoleh hasil  (SL < DL). Tanaman pangan di Kabupaten Banggai Laut, diperoleh hasil yakni (ℓ < 1), yang berarti, wilayah tersebut tidak mampu melaksanakan swasembada pangan. Diharapkan hasil penelitian ini dapat menjadi dasar atau acuan bagi pemangku kepentingan agar dapat meningkatkan luas tanam komoditas pangan, sehingga dapat meningkatkan produktivitas dalam berswasembada.

Abstract

Newly converted land often has a thin topsoil layer, low organic matter content, and a soil structure that is either unstable or tends to be overly porous. Consequently, the process of paddy field formation is not yet complete, meaning that the ability of new paddy fields to absorb NPK is still very limited. This study aimed to evaluate the NPK nutrient status of paddy fields to provide location-specific, effective, and efficient NPK fertilisation recommendations. This study employed a Descriptive Exploratory Survey approach, involving field observations and descriptions of thirteen samples of newly converted paddy soil. Subsequently, each nutrient was analysed in the laboratory using various methods, such as phosphorus (Olsen), potassium (25% HCl), and nitrogen (Kjeldahl). The NPK nutrient content of the soil in the newly developed paddy fields was analysed using the Kriging semivariogram approach. Geostatistical analysis using ArcGIS 10.8 software was employed to interpolate the distribution of NPK nutrient content in the new paddy fields at the study site. The results of this study indicate that the NPK nutrient content of the soil in the new paddy fields in Booy Village, South Balantak Sub-district, is classified as low to moderate. Integrated efforts to improve soil fertility through inorganic fertilisation (such as urea, SP-36, or NPK) to provide rapid nutrient supply, combined with organic amendments to enhance nutrient uptake efficiency, microbial activity, and long-term fertility.
