Abstract

Mango marketing will be profitable for farmers if they are free to determine one of the first buyers in the market and get the maximum profit. But in reality, most mango farmers have a high dependence on selling their crops to middlemen. This is due to farmers' limitations on market information and access to capital. This research aimed at describe variation of first buyers for mango farmers and farmer's behavior in selling mango crops to first buyer parties. This research was conducted by survey research method. Respondents in this study were 50 mango farmers in Sedong District, Cirebon Regency. The data was analyzed using descriptive statistics and crosstabulation analysis. The results show that the variation of first buyers for mango farmers in Sedong District were a) 1 direction: wholesalers, middlemen/traders b) 2 directions: wholesalers, traditional markets; middlemen/traders, traditional markets; middlemen/traders, wholesalers, dan c) 3 directions: wholesalers, exporters, retailers; middlemen/traders, wholesalers, traditional markets. There are mango farmers who have sold to modern retailers, but have stopped doing partnerships because they are unable to fulfill the quality requirements set by modern retailers. However, majority of mango farmers (72%) in Sedong District still sell mango crops to middleman/traders.

Abstract

 Berdasarkan masalah-masalah yang ditemukan dilapangan dan analisis/pembahasan masalah yang terkait dengan tujuan penelitian maka diperoleh hasi bahwa sistem penanggulangan kebakaran hutan berbasis masyarakat telah dilaksanakan secara turun temurun oleh masyarakat dengan menggunakan teknik dan peralatan tradisional. Dalam penyiapan lahan untuk kebun, masyarakat lokal masih melakukan pembakaran, dan selalu membuat sekat bakar berupa rintisan-rintisan di sekeliling areal yang akan dibakar serta melakukan pengawasan pada saat membakar berlangsung untuk menghindari perluasan apiStrategi dalam penanggulangan kebakaran hutan dan lahan berbasis masyarakat adalah peningkatan taraf pendidikan masyarakat, meminimalkan sistem perladangan berpindah (gilir balik) dengan pola tebas bakar dan mencari sumber dana secara mandiri untuk meminimalkan terjadinya bahaya kebakaran yang pada gilirannya akan menambah luasnya lahan kritis, selain itu menghindari  terjadinya konflik kepemilikan lahan, dan juga perlunya keterbatasan tenaga pendamping yang berpengalaman.Rancangan alternatif dalam pengembangan sistem PKHBM adalah upaya-upaya pencegahan dan penanggulangan secara teknis, penerapan pola tanam terpadu, pendekatan partisipatif dalam penyusunan program PKHBM, serta pembentukan usaha kelompok bersama (UKB) dan pendampingan intensif.
