Abstract

Penelitian ini bertujuan untuk melihat Korelasi antara Status hara N,P,K di lahan pertanaman kentang dengan produksi di 27 desa 9 (Sembilan) Kecamatan Sentra Produksi di Kabupaten Karo. Metode penelitian adalah Survey. Penelitian ini dilakukan pada bulan Juli 2018 sampai dengan September 2018. Parameter yang diamati adalah kandungan N-Total, P-tersedia , dan K-tukar tanah serta Produksi kentang per satuan luas (Ha). Data ini diperoleh dari hasil survey dan analisis sampel tanah di Laboratorium Socfindo Bangun Bandar – Dolok Masihul Kabupaten Serdang Bedagai, diolah dengan menggunakan perangkat lunak / software SPSS versi 24.Sifat Kimia tanah menunjukkan bahwa status hara pada lahan yang diteliti berupa status hara N – Total berada pada kriteria rata-rata 11 % sangat tinggi, 37 % status hara tinggi, 48 % status hara sedang dan 4 % dengan status hara rendah. Status hara P-tersedia (P-Bray-I) 96 %  dengan kriteria sangat tinggi dan 4 % pada kriteria sedang, sedangkan status hara K- tukar pada kriteria sangat tinggi sebesar 55 %, kriteria tinggi sebesar 22 %, kriteria sedang sebesar 17 % dan kriteria rendah sebesar 6 %. Sementara produksi kentang yang dihasilkan berada pada kriteria Tinggi sebesar 7 %, sedang sebesar 78 % dan kriteria rendah sebesar 15 %.  Dari hasil uji Korelasi Spearman disimpulkan bahwa Tidak terdapat hubungan yang signifikan antara status hara N-Total, P-Tersedia dan K-Tukar tanah terhadap produksi kentang di lahan petani.

Abstract

This research was conducted in Tanjung Morawa Subdistrict of Deli Serdang Regency in May 2017 until August 2017. This research was a qualitative descriptive phenomenological research with land survey supported by qualitative laboratory analysis. Soil sampling was done at the survey area sequentially based on the location where the soil characteristics were different from the purposive random sampling method, so the result of soil analysis obtained was expected to reflect the actual value. The soil sampling was taken at the top layer at the top soil depth of 0 -20 cm, 60 cm and recording point coordinates by using GPS (global Positioning System). Soil chemical properties analyzed were P2O5 HCl 25% (mg 100 g-1); K2O HCl 25% (mg 100 g-1), and the status of P and K of rice field of Tanjung Morawa District., Rice field with medium P status was T Morawa B Village (20.20 mg 100 g-1), and that with low P status was Pardamean Village (6.34 mg 100 g-1), Wonosari (14.24 mg 100 g-1), Dalu XB (12,82 mg 100 g-1), and  Naga Timbul (9,51 mg 100 g-1). Rice field with high K status was Pardaeman Village (69,07 mg 100 g-1), and Dalu XB (69,07 mg 100 g-1 ). Rice filed with medium K status was Wonosari Village (27.43 mg 100 g-1). Rice field with low K status was. Morawa B (9,32 mg 100 g-1), and Naga Timbul (19,4 mg 100 g-1). P and K fertilization recommendation need to be corrected especially for soils having high P nutrient for efficient use of P fertilizer and eficcient farming. Rice straw needs to be returned to paddy field to increase K2O level of soil, in addition to K fertilizer K.

Abstract

Provision of Compost Bunkers enriched with palm oil mill effluent Aims to determine the treatment of types of compost and the treatment of NPK fertilizer doses on the provision of compost Bunkers are enriched with palm oil mill effluent on the growth of oil palm seedlings The use of compost in the main nursery is one of the most important ingredients applied in growing media. This study was carried out in the Bangun Bandar garden of PT. Socfindo, Serdang Bedagai district, Dolok Masihul sub-district with a altitude of ± 25 m above sea level. This study used a factorial randomized block design with two treatment factors and five replications. Factor I: Compost Type that cosisted of 5 treatment levels, K0: Control, K1: Compost A (25% POME), K2: Compost B (50% POME), K3: Compost C (75% POME), K4: Compost D (100% POME). Factor II: 15-15-6-4 NPK fertilizer dosage level with 5 treatment levels: F0: F1 Control: 25% Standard Fertilization F2: 50% Standard Fertilization F3: 75% Standard Fertilization F4: 100% Fertilization Standard. The resuls showed that treatment of compost types had a very significant effect on plant height, plant hump diameter, shoot wet weight, shoot dry weight and root-shoot ratio of 25% POME. The treatment of NPK fertilizer dosage had a very significant effect on plant tuber diameter, shoot wet weight and shoot dry weight of 25-50% NPK fertilizer dosage.

Abstract

The increase in people's healthy life style has increased the demand for organic rice.  However, this is not supported by sufficient increase in the organic rice production. Therefore, Field School of Organic Farming (FS-OF) was conducted as an effort to increase the organic rice production. This FS-OF activity is aimed to improve farmers' understanding and skill about the organic rice cultivation through demonstration plots. The service activities that have been carried out include the production of demonstration plots for organic and conventional rice cultivation to compare their production, handover of technology transfer tools, training in organic rice cultivation, making the liquid organic fertilizers and organic pesticides, and biochar. The results of community service have increased the understanding of field school participants and increased organic rice production by 10% when compared to conventional rice cultivation
