Abstract

Land evaluation is the process of assessing land potential for various alternative uses. Land suitability evaluation is very flexible, depending on the needs of the area's conditions to be evaluated. Improvement efforts carried out on land will provide an overview of optimal land use in order to increase land productivity. This research aims to determine the level of land suitability for nutmeg plants in Luari Village, North Tobelo District, North Halmahera Regency. This research method uses a purposive sampling method, a type of sampling technique commonly used in scientific research. The main goal of purposive sampling is to produce a sample that can logistically be considered representative of the population. Identification of soil properties in the field is carried out using boring identification techniques, ring samples, and representative profiles. Soil sampling techniques are carried out using a disturbed and undisturbed method to analyze the physical and chemical properties of soil in the laboratory. Research results the actual suitability of land for nutmeg (Myristica. Fragrans Houtt) is divided into marginally suitable class (S3) covering an area of 167.8 Ha at SPL 01, 02, 03, 04, 05 and unsuitable class (N) covering an area of 37.3 Ha at SPL 06, 07, 08, with limiting factors in the marginal suitability class (S3) in the form of soil depth, lack of P2O5, N-Total, and slope, while the limiting factor in unsuitable land suitability (N) is slope.

Abstract

Organic materials refer to substances derived from plant or animal waste and by-products, including manure, composted rice straw, plant residues, sewage, green manure, legume cuttings, and municipal or industrial waste (Zaini et al., 2004, cited in Pirngadi, 2008). This study aims to assess the level of organic material availability and identify the factors influencing it. The parameters analyzed include soil pH, total nitrogen (Total-N), organic carbon (C-organic), organic materials, water content, and the C/N ratio. The research was conducted in Subaim, Bumi Restu Village, in the Wasile District of East Halmahera Regency.The calculation of organic material values involved multiplying the C-organic content by a factor of 1.74%. The findings reveal that the average organic material content across various types of rice field land uses ranges from moderate to high, specifically between 4.12% and 4.43%. The higher levels of organic materials are attributed to the application of rice straw and organic fertilizers during post-harvest and land preparation phases. Conversely, lower organic material values are primarily due to the significant consumption of organic matter by plants during their growth stages

Abstract

Dalam rangka peningkatan produksi pertanian sudah saatnya pengelolaan pertanian diarahkan pada input pemupukan yang ramah lingkungan dan pada lahan-lahan dengan produsktifitas yang rendah terutama dengan kondisi kesuburan rendah baik biofisik dan kimia. Pengelolaan lahan pertanian juga harus mampu memanfaatkan sisa hasil produksi yang tidak terpakai (limbah) dari tanaman maupun hewan untuk dijadikan sebagai pupuk organik. Dalam kegiatan ini sisa limbah pertanian yang digunakan adalah sebagai pupuk organik adalah pupuk kandang ayam, pupuk kandang sapi dan serasah dari cengkeh. Sedangkan media tanah pasir digunakan karena memiliki sifat kesubururan yang rendah baik biofisik dan kimia. Tujuan kegiatan ini adalah memanfaatkan sisa kotoran hewan sebagai pupuk organik dan tanah pasir dalam meningkatkan pengetahuan dan ketrampilan dalam bercocok tanaman sayuran. Sasaran peserta dalam kegiatan ini adalah kelompok tani atau petani yang mengusahakan budidaya tanaman sayuran dengan pendekatan metode penyuluhan dan diskusi mengenai budidaya tanaman serta aplikasi penerapan teknologi pertanian organik. Hasil kegiatan menunjukkan bahwa perlakuan pupuk kandang ayam, merupakan salah satu bahan organik tanah yang mampu memberikan produktifitas berat segar yang lebih baik dibandingkan dengan pupuk kandang sapi dan serasah cengkeh.
