Abstract

Indonesia merupakan salah satu negara produsen dan eksportir kopi terbesar di dunia. Akan tetapi, pertumbuhan volume ekspor kopi di Indonesia lebih rendah dari pertumbuhan produksinya. Rendahnya ekspor kopi Indonesia disebabkan oleh banyak faktor yang mempengaruhi perdagangan kopi Indonesia di pasar internasional. Tujuan dari penelitian ini adalah menganalisis faktor-faktor yang mempengaruhi perdagangan kopi Indonesia di pasar internasional dan menerangkan potensi perdagangan kopi Indonesia di negara tujuan. Metode analisis yang digunakan adalah analisis data panel dengan gravity model dan analisis potensi perdagangan. Hasil penelitian menunjukkan bahwa peubah yang berpengaruh signifikan terhadap ekspor kopi Indonesia adalah GDP riil/kapita Indonesia, GDP riil/kapita negara tujuan, jarak ekonomi antara Indonesia dengan negara tujuan, dan keanggotaan WTO. Sementara itu, Indonesia memiliki potensi untuk melakukan ekspansi perdagangan kopi ke negara-negara tujuan di masa yang akan datang karena perdagangan kopi Indonesia di negara tujuan masih under trade. Implikasi kebijakan adalah Indonesia harus meningkatkan pangsa pasar dengan memprioritaskan untuk mengekspor kopi ke Mesir dan Aljazair karena kedua negara tersebut memiliki pertumbuhan GDP riil/kapita yang tinggi dan perdagangan kopi Indonesia di Mesir dan Aljazair masih under trade.Kata Kunci: Kopi, ekspor, gravity modelIndonesia is one of the largest coffee producer and exporter in the world. However, the growth of Indonesia’s coffee export volume is lower than that of its production. Indonesia’s coffee export is low due to many factors affecting the Indonesia’s coffee trade in international market. The purposes of this study are to explain the factors that influence Indonesia’s coffee trade in international market and the trade potential of Indonesian coffee in destination countries. The analysis methods used are analysis of panel data with gravity model and trade potential analysis. The results showed that variables that significantly influence Indonesia’s coffee exports are real GDP/capita of Indonesia, real GDP/capita of destination countries, economic distance between Indonesia and destination countries, and WTO membership. Meanwhile, Indonesia has potency to expand coffee trade to the destination countries in the future. Therefore, Indonesia should increase the market share by prioritizing of exported coffee to Egypt and Algeria having high in real GDP/capita growth rate.

Abstract

East Flores is sourced reference of superio cashew seeds, so that this region is potentially a superior seed producer of cashew for development program in the future. This study aimed to analyze supply chain management (SCM) and development strategy of cashew superior seed. The research was conducted in East Flores, East Nusa Tenggara Province in June - August 2010. The data used are primary and secondary data. Analysis used model of supply chain management. The results showed that the demand for cashew seed is dependent on the procurement project undertaken by the government. The time often not coincide with the harvest of cashew seeds. Supply chain management applications has been running optimal although more are caused by government intervention in terms of distribution of seeds, so that the optimization process of SCM has not been produced from a process of good business activity. Strategies that can be achieved are: (i) government needs to encourage the process of seed certification by an official agency, (ii) developing the seed garden in an amount sufficient to consider the projected seed demand in the future, either in the form of seeds and scion, (iii) the farmer / farmer group, the owner of seed source should be able to apply the seed stock management so that demand outside the crop seed remain to be fulfilled, (iv) the breeder needs to make improvements in a poly bag seed distribution methods, (v) The Government needs to introduce grafting technology, particularly to the breeder and farmer groups, (vi) The Government needs to do the planning and mapping needs and promoting improved s eed varieties MPF 1.

Abstract

Volume and type of growing media is important to support the growth of rubber seedling (Hevea brasiliensis) for rootstocks. The objective of this study was to determine the growth of rootstock and green budding success of rubber plants in different size of polybag and growing media. The research was carried out since January to December 2013 at the Pakuwon experimental garden, Parungkuda District, Sukabumi Regency, West Java. The study used a randomized block design (RBD) in factorial with two factors and three replications. The first factor is the sizes of polybag: (1) 30 ´ 20 cm, (2) 35 ´ 20 cm, and (3) 40 ´ 20 cm. Meanwhile, the second factor is the growing medium that consists of the mixture of soil and cow manure with 4 proportions: (1) 1 : 0, (2) 3 : 1, (3) 2 : 1, and (4) 1 : 1. Observations were made on the growth of pre-budding rootstock including seedling height, seedling diameter, number of leaves, and the success percentage of green budding. The results showed that the size of polybag has positive effect on the growth of the rubber seedling as rootstock at 6 months old after planting. Moreover, the use of large sizes of polybag (30 x 20–40 x 20 cm) was good for the growth of rootstocks that would be used for green budding. In addition, growing media that consisted of soil and cow manure at a comparison of 1 : 1 gave the highest effect on the growth of rootstock as well as the highest percentage of green budding success. However, there is no interaction between the size of polybag and growing media to the growth of rootstock and green budding success.
