Abstract

The soil aggregate stability index is one of the critical indicators of soil physical quality, primarily related to the soil's ability to absorb water into the soil and the soil's resistance to rainwater splashing and surface flow erosion in the soil erosion process. The study aimed to determine the soil aggregate stability index class criteria using the dry and wet sieving methods on the OSK 10701 sieve type and to identify the stability of soil aggregates on agricultural land, plantations, and forests around the IPB Dramaga campus. The transformation of the soil aggregate stability class criteria from the conventional sieve to the OSK 10701 sieve types gave excellent results with a coefficient of determination (R2) of 0.89. The soil aggregate stability index differs significantly between soil types and land uses. Podsolic Jasinga has a higher aggregate stability index than Podsolik Dramaga, Regosol Dramaga, and Latosol Dramaga in the upper layer (0-20 cm) and the lower layer (20-40 cm). Forests have a better aggregate stability index than conservation agricultural land, conventional agricultural land, rubber plantations, and oil palm plantations. The difference in stability index between land uses is closely related to soil organic matter contents. Although the soil is denser/more compact, the soil in oil palm and rubber plantations has a lower stability index and is classified as unstable.

Abstract

Soil quality is a determining factor for crop production. Therefore, proper assessment of soil quality—by integrating various soil characteristics into a Soil Quality Index (SQI)—is essential to reflect overall soil productivity. This study aimed to determine the SQI and its relationship to fruit crop productivity across seven locations with varying soil characteristics. The research was conducted at SMK PP Saree and SMKN Nisam in Aceh Province; SMKN Gelumbang and SMKN Banyuasin 3 in South Sumatra Province; SMKN Metro and SMKN Gedong Tataan in Lampung Province; and SMKN Kelapa in Bangka Belitung Province. The SQI analysis used eight key soil parameters considered critical for determining and managing crop growth and productivity, namely: effective soil depth, texture, bulk density, pH, organic matter content, cation exchange capacity (CEC), and base saturation. Each parameter was scored on a scale from 0 to 5. The results showed that the Soil Quality Index can effectively assess soil quality using these eight key parameters as a dataset. The studied soils were categorized as having medium to very good quality, with low organic carbon and low CEC identified as the most common limiting factors. Furthermore, the SQI demonstrated a strong positive correlation with fruit crop performance, with a correlation coefficient (r) of 0.832.

Abstract

Kalibaru District is an area in Banyuwangi Regency that has quite a large potential in the agricultural sector, such as Jatirono cocoa farming in Kajarharjo Village. However, the condition of the cocoa plants which tend to be dry and the fruit yields are less than optimal is one of the reasons this study was conducted. The purpose of this study was to determine the factors causing less than optimal growth of cocoa plants by analyzing the physical properties of the soil such as texture, bulk density, and soil permeability. The research methods used were survey methods and laboratory analysis. The soil sampling points for laboratory analysis were taken at 5 points (A, B, C, D, E) with point A as the center point, then points B and D were 50 meters from point A, while points C and E were 62.5 meters from point A. The results obtained for the texture indicators from the five sample points were sandy loam and clay, for the bulk density indicator the results were medium and high, and for the permeability indicator the results were fast and rather fast. So it can be concluded that the sandy clay texture with a more dominant percentage of sand fraction has a texture that tends to be coarse, this texture affects the bulk density of the soil where sand has a greater bulk density compared to clay, this texture also causes the soil's ability to pass water high or fast.

Abstract

The implementation of organic farming in peatland coconut plantations faces challenges such as the low availability of natural nutrients, restrictions on the use of synthetic fertilizers and pesticides, and the demand for soil fertility conservation to ensure sustainable production. One potential solution is the utilization of undergrowth pruning, predominantly composed of Nephrolepis sp., as a source of organic nutrients.This study aimed to determine the decomposition rate and estimate the nutrient release potential from undergrowth pruning in a coconut plantation on peat soil in Riau Province, Indonesia. The litter bag method was employed with an observation period of eight weeks. Results showed that the decomposition rate of the pruned biomass reached 1.92 g per week, with a dry weight reduction of 68%. The most abundant nutrients released during decomposition were potassium (1.79%), phosphorus (0.07%), and copper (5.68 ppm). These findings suggest that undergrowth pruning has the potential to serve as an alternative nutrient source, supporting environmentally friendly coconut cultivation systems on peatlands.

Abstract

The construction of the Soreang-Pasirkoja Toll Road (Soroja) aims to improve connectivity and encourage economic growth in the Bandung area and its surroundings. This study aims to analyze land cover change as well as the economic and environmental impacts caused by the construction of the Soroja Toll Road. The methods used include spatial analysis of land cover changes in 2017-2023 and the Analytical Hierarchy Process (AHP) approach to assess the priority of impacts and formulate recommendations. The results of the study indicate that the construction of the Soroja toll road has caused significant conversion of agricultural land into developed areas by 10,21%, leading to a decline in food production and changes in the livelihood structure of the community. The recommendations include the need to monitor spatial planning, creating green open spaces, managing proper drainage to mitigate environmental deterioration, and involving communities and the government to reduce the impacts caused by the construction of the Soroja Toll Road.

Abstract

Produktivitas sorgum di Indonesia yang masih rendah mendorong pemanfaatan budidaya berkelanjutan. Penelitian ini bertujuan mengetahui sebaran spora FMA pada tanaman hias yang diseleksi, menganalisis pengaruh inokulasi kultur trapping terhadap kepadatan spora dan pengaruh pemberian FMA terhadap pertumbuhan tanaman sorgum. Studi dilakukan Januari-Juni 2025, meliputi identifikasi sebaran spora FMA pada 14 tanaman hias, analisis kultur trapping terhadap kepadatan spora, dan pengaruh aplikasi FMA pada pertumbuhan sorgum. Rancangan Acak Lengkap Faktorial (RALF) digunakan dengan faktor aplikasi mikoriza (tanpa/dengan) dan komposisi media tanam (BIOPOS, sekam, zeolit, dan kombinasinya). Parameter tinggi tanaman dan jumlah daun diamati pada hari ke-30 HST, dianalisis dengan ANOVA dan DMRT (α=5%). Hasil menunjukkan tanaman hias Bugenvil (Bogainvillea sp.) memiliki kepadatan spora FMA tertinggi, dari 14 tanaman hias  dominasi genus Glomus (69.23%) dan Acaulospora (30.77%). Kultur trapping pada tanaman hias Kemuning (Murraya paniculata) (L.) (Rutaceae) menghasilkan kepadatan spora tertinggi (429 spora per 10 g tanah), menjadikannya sumber inokulum potensial. Aplikasi mikoriza dan komposisi media tanam secara signifikan meningkatkan pertumbuhan sorgum. Interaksi mikoriza dengan BIOPOS (A2K1) memberikan pertumbuhan terbaik (tinggi 60.02 cm; 5.50 helai daun), jauh melampaui perlakuan tanpa mikoriza. FMA dari rizosfer tanaman hias berpotensi besar meningkatkan pertumbuhan sorgum, terutama dikombinasikan dengan media tanam yang sesuai seperti BIOPOS, mendukung budidaya sorgum berkelanjutan.

Abstract

Jasa ekosistem pengaturan air di Daerah Aliran Sungai (DAS) Cisangkuy bagian tengah dan hulu mempunyai peran penting untuk kehidupan manusia dan makhluk hidup lain di wilayah bawahnya. Hal ini terkait dengan kebutuhan air sehari-hari ataupun terkait dengan ancaman bencana, dikarenakan kerusakan ekosistem di wilayah atas dapat mendatangkan bencana banjir seperti yang selama ini terjadi di daerah penelitian. Penelitian ini bertujuan memantau jasa ekosistem pengatur air berdasarkan karakteristik biofisik wilayah. Pendekatan yang digunakan berbasis Multi Criteria Evaluation (MCE) terhadap tiga parameter utama yaitu Topographic Wetness Index (TWI), Normalized Difference Vegetation Index (NDVI), dan kemiringan lereng. Data utama yang digunakan adalah DEM SRTM 30m dan citra satelit Landsat 5 TM dan 8/9 OLI-TIRS periode 2000–2024. Hasil kajian menunjukkan bahwa nilai TWI daerah penelitian secara keluasan didominasi oleh kelas “tinggi” (40,72 %) dan “sangat tinggi” (36,79 %). Adapun untuk kelas lereng didominasi oleh kelas “agak curam” (23,09%) dan “curam” (23,07%). Sementara itu untuk kerapatan vegetasi (NDVI) terjadi perubahan luasan yang cukup dinamis. Kelas “sangat rapat” mengalami penambahan luas cukup signifikan dari 0,43 % (2000) menjadi 1,19 % (2004), dan meningkat tajam menjadi 45,26 % (2024). Sementara itu pada kelas “rapat” sempat naik dari 30,53 % (2000) menjadi 38,58 % (2004), namun mengalami penurunan menjadi 26,16 % (2024). Untuk kelas kerapatan “sedang” sempat naik dari 45,05 % (2000) menjadi 47,43 % (2004) namun turun menjadi 18,47% (2024). Dinamika perubahan luas ini berdampak pada nilai jasa ekosistem pengatur air dimana kelas “tinggi” sempat turun dari 37,95% (2000) menjadi 17,23 % (2004), namun meningkat kembali menjadi 37,76 % (2024). Temuan ini menegaskan bahwa telah terjadi perbaikan ekosistem DAS Cisangkuy bagian tengah dan hulu dalam kurun waktu 20 tahun (2004 ke 2024). Diharapkan kondisi ekosistem tetap terjaga atau membaik sehingga dapat menekan dampak banjir wilayah hilir di masa mendatang.

Abstract

Monitoring on irrigated rice field is crucial to anticipate crop damage due to drought and flooding. However, conventional observation methods present complex challenges such as observer bias, point-based data, and limited observational coverage. Observations assisted by multispectral (MS) camera technology mounted on unmanned aerial vehicles (UAVs/drones) were able to address these issues but are still underdeveloped. This study reports the potential use of multispectral cameras mounted on a drone to assess the effects of drought and inundation on rice crops using vegetation indices such as the Normalized Difference Water Index (NDWI), Normalized Difference Vegetation Index (NDVI), and Normalized Difference Red-Edge Index (NDRE). Observations were conducted three times during the vegetative (10 days after transplanting), generative (45 days after transplanting), and ripening (80 days after transplanting) stages on Ciherang and IR64 rice varieties. The rice plants were subjected to different irrigation treatments: drying, flooding, and control. The results showed that the NDRE index had a poor response to vegetation during the vegetative stage but improved during the generative and maturation stages. Meanwhile, the growth of weeds among the rice plants affected the NDVI and NDWI values, especially under dry conditions, making these indices less reliable in such scenarios.

Abstract

Pulau Rupat, dengan 77.39% dari total wilayah daratan 152,371 ha merupakan lahan gambut, mengalami deforestasi, degradasi hutan, dan konversi lahan, sehingga menjadikannya daerah yang rentan terhadap pelepasan emisi gas rumah kaca (GRK) sekaligus strategis untuk pengendalian emisi berbasis lahan. Penelitian ini bertujuan memperkirakan emisi GRK sektor LULUCF melalui identifikasi perubahan penutupan/penggunaan lahan tahun 2000, 2010, dan 2020. Penghitungan emisi dilakukan dengan pendekatan stock difference cadangan biomassa atas permukaan sebagai faktor emisi/serapan setiap penutupan/penggunaan lahan. Proyeksi emisi tahun 2030 dan 2040 dihitung dengan membandingkan perubahan penutupan dan penggunaan lahan historis dengan prediksi penutupan dan penggunaan lahan (skenario Business as Usual/BAU ). Nilai emisi tersebut kemudian dibandingkan dengan nilai emisi sesuai Rencana Tata Ruang Wilayah (RTRW) 2022–2042 (skenario RTRW). Hasil penelitian menunjukkan tren penurunan emisi dari perubahan penutupan/penggunaan lahan dan dekomposisi gambut, yaitu dari 10.37 juta ton CO₂ pada periode 2000–2010 menjadi 7.99 juta ton CO₂ pada periode 2010–2020. Total emisi BAU juga memperlihatkan penurunan, dengan perkiraan 3.79 juta ton CO₂ untuk periode 2020–2030 dan 3.45 juta ton CO₂ untuk periode 2030–2040. Sementara, total emisi berdasarkan skenario RTRW periode 2022–2042 diperkirakan 113% lebih rendah dibandingkan dengan skenario BAU periode 2020–2040 yang mencapai 3.95 juta ton CO2.
