Abstract

Corn (Zea mays L.) is the second most important food crop after rice and is a cereal crop that grows in various regions worldwide. Local varieties of corn in North Sumatra require high nutrient levels for optimal cultivation, particularly nitrogen (N), which is commonly supplied through urea fertilizer. The high demand for nitrogen in urea often leads farmers to apply it in inappropriate doses, resulting in several agronomic issues. This study aims to evaluate the growth of local varieties of corn in North Sumatra in response to different doses of urea fertilizer. The research was conducted in the experimental field in Perbaungan Village, Hulu Bilah District, Labuhanbatu Regency, North Sumatra, from December 2024 to February 2025. A Non-Factorial Completely Randomized Design (CRD) was employed, consisting of five treatment levels, each repeated four times. The urea fertilizer doses applied were as follows: control (no treatment), 2 g/polybag, 4 g/polybag, 6 g/polybag, and 8 g/polybag. The results indicate that varying doses of urea fertilizer significantly influence the growth of local North Sumatra corn plants, particularly in plant height and stem diameter. The optimal dose of urea fertilizer for promoting the development of these corn plants is determined to be 4 g/polybag.

Abstract

Currently, the government continues to encourage the development of oil palm plantation areas with the aim of boosting domestic economic activity. Tanjung Siram has a large area of land and has the potential to be developed into plantations, especially oil palm plantations. This regency has a land area of 1056 ha. Therefore, an evaluation of land suitability needs to be carried out in order to know the actual and potential land suitability class recommendations for oil palm plantations in that village. The stages in the research included secondary data collection, pre-survey, main survey and soil analysis in the laboratory. Land suitability classification is done by matching method. From the research results it is known that the limiting factors in the actual land suitability class at the study site were temperature, water availability, nutrient retention, and erosion hazard. After improvements have been made with good land management, the land suitability class can be increased with a potential land suitability class, which was previously classified as S3, increased to S2, and previously classified as S2, can be increased to S1. Thus, to obtain good oil palm growth in this region, it is necessary to improve the limiting factors on each land.

Abstract

This study aims to determine the analysis of the palm oil processing identification process at PT. Asam Jawa in South Labuhanbatu Regency. The determination of the research location was done intentionally (purposive). The subjects of the study were the parties involved in the study, namely PT. Asam Jawa and the object of the study was the production of crude palm oil. Data collection was carried out using historical data methods and literature studies. The results of the study showed that the palm oil processing process starts from (a) fruit harvesting; (b) transportation of FFB; (c) receipt and sorting of FFB; (d) boiling station (Sterilizer); (e) threshing station; (f) pressing station; and (g) purification station (Clarification Station)

Abstract

Salah satu permasalahan yang dihadapi oleh Masyarakat Desa Tanjung Medan adalah kurangmya pengetahuan mengelola limbah kotoran ternak sapi menjadi pupuk organik cair. Pupuk organik cair merupakan bahan pembenah tanah yang paling baik dan alami dibandingkan dengan pupuk anorganik. Kualitas pupuk organik cair harus memenuhi standar mutu atau persyaratan teknis minimal pupuk organik. Kegiatan pengabdian kepada masyarakat yang dilakukan di Desa Tanjung Medan, Kecamatan Bilah Barat, Kabupaten Labuhanbatu, Provinsi Sumatera Utara bulan Juli 2022 sampai dengan Agustus 2022 dengan tujuan adalah untuk memberikan informasi dan melakukan pembuatan pupuk organik cair dari kotoran sapi secara fermentasi anaerob kepada para petani. Sampel pupuk organik cair dari fermentasi kotoran sapi dianalisis di Laboratorium Analitik PT. Socfin Indonesia. Data tersebut dibandingkan dengan Baku Mutu Pupuk organik cair (SNI) dari Permentan No.261/Kpts/SR.310/M/4/2019. Hasil analisis laboratorium menunjukkan bahwa fermentasi kotoran sapi mempunyai C/N Ratio 5,766; pH 7,31 yang memenuhi standar mutu, namun kandungan hara makro N, P, K masih dibawah standar mutu.

Abstract

The transformation of tropical landscapes due to agricultural expansion constitutes a significant global environmental challenge. Current land-cover classification methods, however, provide limited differentiation among agricultural management systems. This study develops an agriculture-focused land-cover classification workflow that fuses Landsat 9 optical imagery and PALSAR-2 L-band SAR across a ≈2,500 km² study area in Jambi Province, Sumatra, Indonesia, to enhance discrimination of crop systems and improve spatial coherence via object-based enhancement. A 22-class land-cover taxonomy was supported by 14,029 strategically collected training points. Feature engineering produced 29 predictor variables, including conventional vegetation indices, agricultural-specific metrics, water indicators, and SAR-derived structural features. Models were evaluated on an independent test dataset comprising 4,209 samples. An agriculture-weighted Random Forest classifier with strategic class weighting was implemented and followed by Simple Linear Iterative Clustering (SLIC) object-based enhancement to suppress speckle and enforce spatial contiguity. The classification achieved an overall accuracy of 53.7%, with exceptional performance for estate crop systems (F1 = 94%) and reliable forest discrimination. SLIC reduced salt-and-pepper noise by 99.5% and substantially improved spatial coherence metrics, transforming fragmented pixel-based outputs into operationally viable products. Despite these gains, discriminating smallholder mosaics remains challenging and likely requires additional temporal or higher-resolution inputs.
