Abstract

Lahan bekas tambang emas dan batu bara di Desa Batu Botuk Kecamatan Muara Komam Kabupaten Paser masih berupa lahan urugan yang belum dimanfaatkan secara optimal. Potensi lahan bekas tambang dapat diketahui dengan melakukan analisis kemampuan lahan serta dapat digunakan untuk meminimalisir risiko kesalahan pengelolaan lahan. Hasil analisis kemampuan lahan diharapkan dapat menjadi pedoman untuk pemangku kebijakan dalam mengolah lahan bekas tambang secara optimal. Tujuan penelitian ini adalah untuk mengetahui kemampuan lahan bekas tambang dan rekomendasi arahan penggunaan lahan berdasarkan kondisi kemampuan lahan eksisting pada daerah penelitian, peraturan daerah yang berlaku, serta hasil FGD. Pedoman analisis kemampuan lahan dalam penelitian ini mengacu kepada Arsyad (2010) dan Peraturan Menteri Negara Lingkungan Hidup Nomor 17 tahun 2009 Tentang Pedoman Penentuan Daya Dukung Lingkungan Hidup Dalam Penataan Ruang Wilayah. Hasil penelitian menunjukkan bahwa 1) kelas kemampuan lahan pada daerah penelitian adalah kelas II dan kelas III. Kemampuan lahan kelas II terdapat pada unit lahan 2 dan unit lahan 3. Kemampuan lahan kelas III terdapat pada unit lahan 1 dan unit lahan 4; 2) arahan penggunaan lahan didasarkan oleh jenis tanaman domestik yang biasanya dibudidayakan oleh masyarakat sekitar, hasil studi literatur, RTRW Kabupaten Paser Tahun 2015 – 2035, dan hasil FGD. Pada lahan kelas II-III yang belum sesuai penggunaannya atau belum dimanfaatkan secara optimal, pilihan penggunaan lahan yang dapat dilakukan yaitu 1) tanaman semusim; 2) tanaman perkebunan; 3) hutan produksi; 4) penggunaan nonpertanian. Berdasarkan hasil FGD bersama penduduk dan pemangku jabatan di Desa Butok maka dihasilkan keputusan bahwa lahan bekas tambang akan ditanami tanaman semusim dan tanaman perkebunan dengan sistem pertanian terpadu. Sisa lahan lainnya berupa danau akan digunakan untuk perikanan dan pariwisata.

Abstract

Oil palm development in Indonesia faces various agronomic constraints, especially related to soil chemical properties that are less supportive of productivity. This study aims to identify the status of soil chemical properties on oil palm land in Saliki Village, Muara Badak District, East Kalimantan, to support more appropriate land management. The research was conducted from September to November 2024 using a purposive random sampling method on 13 hectares of land, with six sampling center points and four subsamples per point. Laboratory analysis was conducted on soil pH, C-organic content, total N, available P, potential K, cation exchange capacity (CEC), and base saturation. The results showed that the soil in the 6-year-old oil palm land had a pH of 3.63-3.93 and base saturation of 13.69-13.81%, while at the age of 15 years, the pH decreased to 3.12-3.38 and base saturation was only 4.62-6.95%. Meanwhile, available P and potential K levels tended to increase with increasing plant age. Based on these findings, fertilization is recommended according to the IOPRI standard for mineral soils as follows: for 6 years old, urea 2.75 kg/year, TSP 1.75 kg/year, and KCl 2.75 kg/year, while for 11 and 15 years old, urea 3.25 kg/year, TSP 2 kg/year, and KCl 3 kg/year. This study emphasizes the importance of periodic monitoring of soil chemical properties as a basis for sustainable management of oil palm plantations.

Abstract

Babulu District in Penajam Paser Utara Regency, East Kalimantan, is an area with high potential in the development of oil palm plantations. However, the increase in oil palm land area raises the issue of land use change, especially rice field conversion. This study aims to map and analyze changes in oil palm land use from 2015 to 2024 using Landsat 8 OLI/TIRS and Landsat 9 OLI/TIRS satellite imagery. The methods used include image pre-processing, onscreen digitization, supervised multispectral classification, and map overlapping to detect spatial changes. The map accuracy test was carried out by cross-checking the results of image digitization and multispectral classification with 30 sample locations in the field that had been checked for veracity. The results of the study show that the use of oil palm land in Babulu District in 2015 was 14,129.25 ha. The use of oil palm land in Babulu District in 2024 will be 15,817.36 ha. The change in the area of oil palm land use in Babulu District increased by 1688.11 ha in a period of nine years, with a rate of change of 187 ha/year. This change is dominated by the northern area of Babulu District which has a steep topography and is the main location for palm oil expansion, driven by topographic factors, the presence of large companies, and the economic value of palm oil commodities. This study shows the importance of spatial monitoring in sustainable land use management and the need for policies that balance economic growth and productive land conservation.

Abstract

This study aims to map the potential of the livestock sector in Berau Regency using the Location Quotient (LQ) and Geographic Information System (GIS) approaches to identify basic commodities and their spatial distribution patterns. A quantitative approach was used to analyze secondary data from the Animal Husbandry Service and related agencies. At the same time, spatial analysis was conducted to visualize the distribution of livestock populations and regional development zoning. The results of the LQ analysis indicate that goats, buffalo, and cattle are basic commodities with significant contributions to the regional economy. Meanwhile, native chickens and ducks serve as complementary sources of food, supporting local food security. The results of the spatial mapping show a contrasting distribution pattern between inland and coastal areas. The integration of LQ and GIS resulted in a livestock development zoning consisting of: (1) a ruminant base zone in the central-southern region, (2) a poultry base zone in coastal and island areas, and (3) a support zone in non-base areas such as Tabalar and Teluk Bayur. These findings confirm that the development of the livestock subsector in Berau Regency requires a spatial and evidence-based planning approach to encourage land efficiency, economic equity, and environmental sustainability. Therefore, the results of this study can serve as a basis for strategic planning in the development of competitive and sustainable livestock areas at the regional level.

Abstract

Oil palm plantations in Babulu District are increasing because they have high economic value. Continuous tillage of the soil can cause nutrients in the soil to decrease and be supplemented by fertilizer application by farmers. This research was conducted with the aim of mapping the soil nutrient status (N, P, K, and pH) on oil palm land in Babulu District. This research was carried out by making a map of oil palm land use in 2024 in Babulu District. Furthermore, soil sampling was carried out using the purpose random sampling method in oil palm land in Babulu District and N-total, P-available, K-available, and pH analysis was carried out at the Soil Laboratory, Faculty of Agriculture, Mulawarman University. Nutrient status mapping was made using IDW (Inverse Distance Weighting) metode which is interpolation data based on the assumption that the value of unsampled points can be predicted as a weighted average of known values. The results of the study showed that the pH status of oil palm land in Babulu District was divided into sour and very sour. The N-total status in Babulu District is divided into very low, low, and medium. The P-available status in Babulu District is divided into very low, low, high, and very high. The K-available status in Babulu District is divided into medium, high, and very high.

Abstract

This study evaluates the sustainability status of the agricultural sector in Berau Regency, East Kalimantan, using a Multiaspect Sustainability Analysis (MSA) approach supported by EXSIMPRO software. The assessment focuses on three main dimensions: economic, institutional, and technological sustainability. Primary data were obtained from 30 key stakeholders, including farmers, extension officers, cooperatives, and local government representatives, and were complemented by secondary data from official sources. The results show that the economic sustainability index is 42.86%, indicating a low level of sustainability, mainly due to low productivity, fluctuating Farmer Exchange Rates (NTP), and limited market access. The institutional dimension records a borderline sustainability status of approximately 50%, reflecting weak farmer organizations, limited extension intensity, and insufficient regulatory support. The technological dimension performs relatively better, with a sustainability index of 65.8%, driven by partial adoption of agricultural machinery, superior seeds, and basic digital technologies. Leverage sensitivity analysis reveals an equal leverage value of 0.5 across all dimensions, indicating strong interdependence and the need for simultaneous, integrated interventions. Scenario simulations suggest that targeted policies could increase the economic sustainability index to 50% and the technological index to 87.5%. Key structural constraints include long marketing chains, inadequate irrigation, land conversion, labor shortages, and low digital literacy. The study concludes that integrated interventions focusing on technology adoption, institutional strengthening, and market access improvement are essential to enhance the overall sustainability of Berau Regency’s agricultural sector.
