Authors: Sukiada Ni Wayan Rainy Priadarsini , Parameswari Anak Agung Ayu Intan
Published: May 2020

Kopi Gunung Catur adalah merek kopi specialty Arabika yang berasal dari Kintamani. Kopi arabika ini memiliki kualitas ekspor. Merek Gunung Catur dibudidayakan oleh kelompok tani bernama Subak Abian Tri Guna Karya. Saat ini, branding memiliki peran penting dalam promosi di pasar internasional. Pemerintah Indonesia mulai membangun nation branding untuk kopi Arabika Indonesia demi menghindari klaim dari negara lain dan memperluas akses pasar. Demikian juga untuk Kopi Gunung Catur, harus ada strategi yang tepat untuk meningkatkan citra kopi ini sehingga akses pasarnya semakin terbuka lebar. Anholt mengatakan ada tiga strategi yang dapat meningkatkan citra produk suatu negara, yaitu kompetensi, kontribusi dan komunikasi. Kopi Gunung Catur yang telah memiliki sertifikat Indikasi Geografis (IG) menunjukkan kemampuan petani di Desa Catur untuk mengolah kopi dengan kualitas yang baik. Karena kopi ini dibudidayakan secara organik, maka membantu meningkatkan citra Indonesia di mata dunia tentang perlindungan lingkungan. Filosofi Tri Hita Karana yang digunakan sebagai landasan pembudidayaannya yang mensinergikan perilaku manusia dan menjaga keseimbangan alam memperkuat citra kopi ini untuk pelestarian alam. Kopi Gunung Catur telah memenuhi strategi kompetensi dan kontribusi. Namun, akses pasar masih dikeluhkan oleh petani dan pengolah kopi Kopi Gunung Catur. Melalui metode deskriptif kualitatif, ditemukan permasalahan bahwa masih kurangnya pengembangan strategi nation branding ketiga, yaitu komunikasi. Strategi komunikasi berkontribusi besar dalam mendukung akses pasar, terutama untuk kegiatan ekspor. Memasuki era industrialisasi 4.0, penguasaan Teknologi Informasi (TI) dan semangat kewirausahaan modern adalah strategi utama untuk mengembangkan kegiatan ekspor. Ini belum dikembangkan secara optimal oleh petani dan pengusaha kopi Gunung Catur. Maka melalui penelitian ini ditemukan bahwa penggunaan teknologi dan semangat kewirausahaan modern (technopreneurship) menjadi basis strategi komunikasi sebagai langkah strategis dalam meningkatkan peluang ekspor bagi produsen Kopi Gunung Catur.

Continuity of sustainable coffee production lines is an importantdemand that needs to be done. The application of coffee production systems with shade(agroforestry) in the catchment area is very important in ensuring environmentalsustainability. This study aims to analyze the income performance of agroforestry coffeebased on the land status in Hulu Das Sekampung. The research uses survey methods. Fielddata exploration conducted in April-November 2016 is located in Datar Lebuay and SinarJawa Villages. Air Naningan, Tanggamus, Lampung. The descriptive statistical analysismethod is used to explain the performance of agroforestry coffee production at the researchlocation. Based on the results and discussion it was concluded that farmers with landownership status had the highest level of coffee farming income compared to the land statusof HKm and non-HKm. Agroforestry coffee farmers obtain sources of income from coffeeproduction, MPTS production, and other crop production (multiple cropping). The averagecontribution of coffee farming income is 22% of the total farm income. Coffee contributes22% to the total income of farmer households. Farmer's household income with the status ofland ownership is the highest compared to the land status of HKm and Non-HKm. Thediversity of income sources of upstream farmers in the watershed. The villages that comefrom various vegetation plants are important in maintaining land cover as a catchment area.The practice of agroforestry coffee is an adaptation of sustainable production in the upperwatershed Sekampung.

Reduced productive rice fields to non-paddy fields, most possible extension of the nationalrice cultivation area to the suboptimal lands reaching Â± 91.9 million ha. Technologypackages that can be applied include the use of new improved rice varieties through theassembling of varieties that have high yield potential, resistant to suboptimal soil stress. Theobjective of the research is to produce new superior rice varieties that are available invarious environments. The study used a split-plot design, as the main plot is an environmentconsisting of rice paddies and gogo, as a subplot is the genotype of rice. The treatment ineach environment is prepared using the Randomized Complete Block Design (RCBD). Thetreatment consisted of 10 new rice strains and four varieties as a comparison. Variablesobserved (1) plant height; (2) the maximum number of shoots; (3) number of productiveshoots; (4) long panicle; (5) the number of grains per panicle; (6) the amount of graincontent of each panicle; (7) the number of empty grains per panicle; (8) weight of 1000grains of grain; (9) grain yield of each clump; (10) grain yield per hectare. Data wereanalyzed by variance if there was a difference between mean, median treatment, followed byLsd test at 5% level. The adaptability and yield stability of each strain was determined basedon the value of the coefficient of diversity (KK) (Francis and Kenneberg, 1978) in Syukur etal., (2012). The results showed that seven new rice strains had adaptations both planted asupland rice and lowland rice, namely strains B3, B4, F2, F3, H1, H4, and L2.
