Penelitian ini bertujuan untuk mengetahui lokasi pegembangan pertanian padi, palawija dan holtikultura dengan menggunakan metode analisis Location Index (LI), Concentration Index (CI), Specialisation Index (SI) dan Location Quontient (LQ). Penelitian ini menggunakan data sekunder Badan Pusat Statistik Kabupaten Bulungan. Berdasarkan hasil analisis (LI) Terdapat 6 “Kecamatan” yang menunjukkan nilai positif. sehingga memiliki presentase terbesar dibanding wilayah lain yaitu: Peso Hilir (6,565) mangga, Tanjung Palas Barat (4,130) durian, Tanjung Palas (32,331) durian, Tanjung Selor (44,216) mangga, Tanjung Palas Utara (36,771) Jagung, Bunyu (64,148) salak. Selanjutnya hasil analisis Concentration Index (CI) juga terdapat 6 “Kecamatan” yang potensial nilai (CI>1).sebagai daerah konsentrasi yaitu: Peso Hilir (3,364) pepaya, Tanjung Palas Barat (1,266) durian, Tanjung Palas (3,794) durian, Tanjung Selor (1.595) mangga, Tanjung palas Utara (6,489) jagung, Bunyu (8,372) salak. Sementara hasil analisis (LQ) Terdapat 10 “Kecamatan” yang memiliki potensial nilai (LQ>1). Sehingga menjadi basis untuk “komoditas” tersebut yaitu: Peso 9,579 mangga, Peso Hilir (3,132) pepaya, Tanjung Palas Barat (3,480) durian, Tanjung Palas (3,064) durian, Tanjung Selor (3,841) mangga, Tanjung Palas Timur (1,464) cabai, Tanjung Palas Tengah (13,058) pepaya, Tanjung Palas Utara (4,255) jagung, Sekatak (49,040) salak, Bunyu (54,148) salak. Terakhir hasil analisis (SI) 10 “Kecamatan” potensial dimana sebagai daerah spesialis untuk “komoditas” tersebut yaitu: Peso (45,533) mangga, Peso Hilir (4,044) pepaya, Tanjung Palas Barat (47,596) durian, Tanjung Palas (43,646) durian, Tanjung Selor (15,078) mangga, Tanjung Palas Timur (128,350) cabai, Tanjung Palas Tengah (22,871) pepaya, Tanjung Palas Utara (31,359) jagung, Sekatak (53,416) salak, Bunyu (37,659) salak. Pusat pengembangan palawija Tanjung Palas Utara, holtikultura Tanjung Palas Timur buah – buahan sekatak. Diharapkan pemerintahan Kabupaten Bulungan dapat mengelola daerah yang menunjukkan keunggulannya.

Kata Kunci: Analisis Location Index, Concentration Index, Specialisation Index dan Location Quontient

This study aimed to determine the location ofthe development of rice, secondary crops and horticulture agriculture using the Location Index (LI), Concentration Index (CI), Specialization Index (SI) and Location Quonient (LQ) analytical methods. This study used secondary data from the Central Bureau of Statistics of Bulungan Regency. Based on the results of the analysis (LI) there were 6 "Districts" which showed positive values. so that it had the most significant percentage compared to other regions: Lower Peso (6,565) mango, Tanjung Palas Barat (4,130) durian, Tanjung Palas (32,331) durian, Tanjung Selor (44,216) mango, Tanjung Palas Utara (36,771) Corn, Bunyu (64,148) snake fruit. Furthermore, the results of the analysis of the Concentration Index (CI) also showed 6 "Districts" with potential values (CI> 1) as concentration areas: Lower Peso (3,364) papaya, West Tanjung Palas (1 ,266) durian, Tanjung Palas (3,794) durian, Tanjung Selor (1,595) mango, North Tanjung palas (6,489) corn, Bunyu (8,372) salak. While the results of the analysis (LQ) there were 10 "Districts" that had potential value (LQ> 1). So that it became the basis for these "commodities"' Peso 9,579 mangoes, Peso Downstream (3,132) papayas, Tanjung Palas Barat (3,480) durians, Tanjung Palas (3,064) durians, Tanjung Selor (3 ,841) mangoes, Tanjung Palas Timur (1,464) chilies, Tanjung Palas Tengah (13>058) papaya, Tanjung Palas Utara (4,255) corn, Sekatak (49,040) zalacca, Bunyu (54,148) zalacca. Finally the results of the analysis (SI) of 10 potential "Districts" where specialist areas for these "commodities" were: Peso (45,533) mangoes, Peso Hilir (4,044) papayas, Tanjung Palas Barat (47,596) durians, Tanjung Palas (43,646) durians, Tanjung Selor (15,078) mango, Tanjung Palas Timur (128,350) chili, Tanjung Palas Tengah (22,871) papaya, Tanjung Palas Utara (31 ,359) corn, Sekatak (53,416) zalacca, Bunyu (37,659) zalacca as the centre for developing palawija in North Tanjung Palas, and horticulture of Sekatak's fruit in East Tanjung Palas. It is expected that the Bulungan Regency government can manage areas showing their superiority. Keywords: Analysis of Location Index, Concentration Index, Specialization Index and Location Quontient.
