Pembangunan pertanian tidak hanya diarahkan pada komoditas pangan tertentu, akan tetapi juga diarahkan pada komoditas-komoditas yang mempunyai nilai ekonomis tinggi (Putri, 2007). Komoditas pangan yang mempunyai nilai ekonomis tinggi dan banyak diusahakan masyarakat akhir-akhir ini yaitu komoditas pangan yang berasal dari subsistem pertanian hortikultura. Pemasaran komoditas hortikultura menjadi tindakan ekonomi yang berpengaruh terhadap tinggi rendahnya pendapatan petani. Sayuran merupakan jenis tanaman hortikultura yang banyak dipilih dalam usahatani, salah satu komoditas pilihan masyarakat adalah cabai merah (BPS DIY, 2016). Cabai merah di Indonesia menjadi sayuran penting didasarkan pada volume perdagangan, baik di pasar produsen maupun pasar konsumen. Produksi yang tinggi secara otomatis akan memberikan keuntungan besar bagi petani jika tidak disertai pemasaran yang baik dan efisien. Pemasaran akan berjalan baik dan efisien apabila informasi tentang produk dapat diketahui oleh semua pihak, baik informasi jenis komoditi, mutu, harga, pasar, dan ketersediaan (Kumalawati dalam Listiyorini, 2008).

4. When the price of chili falls, curly red chili farmers will be harmed
Curly red chili is a vegetable that often experiences price fluctuations
When the price of chili falls, curly red chili farmers will be harmed
Market integration analysis is needed to see whether changes in product prices at the retailer's level will affect changes in market prices at the farm level.
Market integration also shows whether or not information flows smoothly at all market levels. Non-integrated markets will provide inaccurate information that distorts marketing decisions at the market level. The existence of inadequate price information between producers and consumers causes information asymmetry.

5. Objectives
This study aims to determine the price behavior at the producer market in Kulonprogo Regency and the consumer market in Pasar Induk Kramat(PIKJ), and the vertical integration between the two markets.

6. Methodology
The basic method used in this research is descriptive to find out the description of the data to analyze
The type of data used in this study is secondary data in the form of monthly prices of curly red chili at the producer level in Kulonprogo Regency and the consumer market in PIKJ during the period of
The behavior of curly red chili prices is analyzed using a graphical and mathematical approach. Graphic analysis is used to describe the monthly prices of curly red chili during displayed in graphical form.
Graphical analysis is done using Microsoft Excel software. Mathematical analysis is done using Coefficient of Variation (CV) to determine the fluctuations in the price of curly red chili.

7. The CV formula is as follows:
Information:
s = standard deviation
x = the average price of curly red chili
n = number of samples
CV = coefficient of variation

8. Pit = b1 (Pit-1) + b2 (Pat - Pat -1) + b3(Pat -1)
The vertical integration between the producer market in Kulonprogo Regency and the consumer market in PIKJ is analyzed using the Index of Market Connection (IMC) model. The IMC model using the Autoregressive Distributed Lag Model approach is formulated as follows:
Pit = b1 (Pit-1) + b2 (Pat - Pat -1) + b3(Pat -1)
Information:
Pit = the price of curly red chili in the producer market in the month t
Pit-1 = the price of curly red chili in the producer market in month t-1
Pat = the price of curly red chili in the consumer market in the month t
Pat -1 = the price of curly red chili in the consumer market in month t-1
bi = regression coefficient

9. b1 = regression coefficient of Pit-1

Petani di Kabupaten Kulonprogo menggunakan dua jenis lahan untuk membudidayakan cabai merah keriting yaitu lahan pasir serta lahan sawah. Tentunya keduanya memiliki kekurangan dan kelebihannya masing-masing. Budidaya cabai merah keriting di lahan pasir mampu memproduksi cabai merah keriting dalam jumlah yang lebih besar dibandingkan di lahan sawah, karena hama di lahan sawah lebih banyak dan cabai merah keriting cenderung berproduksi dengan jumlah dan kondisi yang baik pada lahan yang tidak lembab yaitu lahan pasir. Cabai merah keriting di lahan pasir masuk musim tanam pada bulan April dan Agustus, sedangkan untuk jenis lahan sawah cabai merah keriting mulai ditanam pada akhir musim penghujan yaitu April.
