Abstract

Phytophthora palmivora (Butl.) is a major obstacle in cocoa cultivation worldwide. The study aimed to determine the morphological character and pathogenicity of P. palmivora Pakuwon isolate. The study was carried out from November 2020 to January 2021, which consisted of 3 activities e.g. (1) pathogen isolation, tests on growth rate and colony formation, and stimulation of sporangia, zoospore, and clamydospore formation, which was performed  in CMA, PDA, and mung bean media. The parameters observed were colony shape, growth rate, shape and size of sporangia, papillae, and sporangiophores, also chlamydospore and hyphal diameters; (2) To determine the possibility of different mating types, two isolates were grown on CMA medium in one petri dish; (3) The pathogenicity test, using a detached fruit assay by inoculating the cocoa pods with mycelium plug and zoospores. The patogenicity test was conducted in a completely randomized design with 4 replications, and the parameter observed was the area of the spot. The isolation obtained 3 isolates, the mycelium of all three isolates showed white in color, cottony, and  no pattern in shape. The diameters of hyphae and chlamydospores were 5.6 - 6.3 mm and 39.0 - 43.2 mm, respectively. The sporangia were ovoid, ellipsoid, subsperic, obpyriform, and irregular. Sporangia measured 5.6 - 60.1 mm in length and 30.4 - 32.9 mm in width. Papillae were obviously visible with an average length of 6.8 mm. Test on mating types showed no oospores formed. PPkw1 isolates showed higher growth rates and more pathogenic than PPkw2 and PPkw3. The difference of pathogenicity of each P. palmivora isolates originated from Pakuwon can be used for selection of cocoa resistance in the future.

Abstract

Leaf rust disease (Hemileia vastatrix) is commonly controlled using synthetic fungicides.  Plant oils and extracts are expected to reduce the pathogen. The research aimed to determine the effectiveness of clove, Reutealis trisperma, and neem oils, and Ageratum conyzoides extract against H. vastatrix. The study was conducted in the laboratory and greenhouse of the Indonesian Industrial and Beverage Crops Research Institute and smallholder coffee plantation in Garut, West Java, from January to December 2018. The A. conyzoides were extracted in the laboratories.  Plant oils and extract's effectiveness was tested in vitro against the germination of urediniospore and in a greenhouse to inhibit disease development. The in vitro experiment were evaluated the eight concentrations of extract and oil were:  0 (steril water), 250, 500, 1000,  1500, 3000, and 5000 ppm. Whereas, in the greenhouse experiments used three concentrations of 1000, 2500, and 5000 ppm of the extract and oil, and 2000 ppm of Mankozeb (positive control). The greenhouse test was carried out on Arabica coffee plants, completely randomized design and five replications.  The number of spots, disease intensity, and plant growth were examined periodically. The results showed that all of the the extract and oil inhibited the urediniospores germination, and the most effective concentrations were 500 ppm, 3000 ppm, and 5000 ppm. A. conyzoides extract, and clove oil effectively suppressed the infection of H. vastatrix by 75.99% and 64.00%, respectively, and comparable to the synthetic fungicide (68.00%).

Abstract

Coffee is a commodity that has an important role in the national economy. Currently, coffee cultivation is threatened by climate change caused by global warming due to increased green house gas (GHG) emissions. The organic  plantation model is a farming model that is considered to increase soil and crop productivity, reduce GHG emissions, and increase carbon sequestration effectively. The study was aimed to estimate GHG emissions and carbon stocks in organic and conventional coffee plantations in Badung Regency, Bali Province and  Laboratory in Balai Penelitian Lingkungan Pertanian, Pati, Jawa Tengah Province, in July 2018. The study was conducted in smallholder coffee plantations in Badung Regency and the analysis was carried out at Laboratory of Indonesian Agricultural Environtment Research Institute. This study used a survey method, while the sampling used a purposive sampling method in organic and conventional coffee plantation. GHG emissions measurement was carried out with a close chamber method by simultaneously the carbon stocks measurement was carried out with the non-destructive method for plant biomass and destructive for understorey. The results showed that organic and conventional coffee plantations emitted GHG by 20.71 and 39.75 ton CO2e ha-1 and stored carbon stock by 227.56 and 288.31 ton CO2e  ha-1, respectively. The differences in GHG emissions and carbon stocks are partly due to differences in management system and the diversity of plant. The management system of the organic coffee plantation should be improved to support handling of the impacts of climate change in Bali Province.

Abstract

Peningkatan mutu dan keekonomian merupakan hal yang sangat penting untuk meningkatkan nilai ekspor kopi di Indonesia. Kopi Arabika Sigarar Utang yang merupakan salah satu jenis kopi terbaik di Indonesia dapat ditingkatkan nilai tambahnya melalui penyangraian kompleks yang merupakan metode penyangraian terbaik. Penelitian dilakukan di Balai Penelitian Tanaman Industri dan Penyegar (Balittri), Sukabumi, Jawa Barat, mulai Januari sampai November 2020, dengan tujuannya untuk: (1) mengevaluasi pengaruh temperatur awal dan derajat penyangraian terhadap kualitas biji kopi Arabika Sigarar Utang, dan (2) mengevaluasi neraca massa dan kelayakan ekonomi pada perlakuan penyangraian terbaik. Percobaan dilakukan dengan rancangan acak lengkap faktorial, 2 faktor, dan 2 ulangan. Faktor pertama adalah temperatur awal yang terdiri dari 2 taraf, yaitu: temperatur 185 oC dan 210 oC. Faktor kedua adalah derajat sangrai yang terdiri dari 2 taraf, yaitu: derajat ringan-sedang dan derajat sedang-gelap. Peubah yang diamati adalah kadar air, kadar abu, densitas kamba, nilai brix, total asam tertitrasi, pH, aktivitas antioksidan, dan kadar kafein. Hasil penelitian menunjukkan bahwa metode penyangraian kompleks dengan temperatur awal 210 oC dan derajat penyangraian ringan-sedang menghasilkan mutu kopi Sigarar Utang yang diperoleh dari Kebun Percobaan Gunung Putri, Balittri, paling mendekati mutu I SNI 01-3542-2004. Biji kopi sangrai yang dihasilkan memiliki cita rasa istimewa (skor 86,51) sehingga dapat memberikan nilai tambah yang tinggi. Nilai kelayakan ekonomi produksi sangat meyakinkan sehingga layak untuk diadopsi oleh industri kopi skala kecil-menengah.

Abstract

Coffee is a beverage that is widely consumed around the world. Proper packaging and storage temperature may extend shelf life of ground coffee. The study aimed to analyze the shelf life of ground Arabica coffee stored in different packaging types and temperature, conducted at smallholder coffee plantations in Garut Regency and the Integrated Laboratory of Indonesian Industrial and Beverage Crops Research Institute, Sukabumi, from June to August 2018. A completely randomized design in factorial was used with 3 factors and 2 replications. The first factor was the packaging type  which consisted of 3 types: thick alumunium  foil 65m (AF65), thick alumunium  foil 130m (AF130), and thick lamination 114m (L144). The second factor was the storage temperature which consisted of 3 levels: 25 oC, 35 oC, and 45 oC, while the third factor was the storage period which consisted of 5 levels: coffee unstored, and coffee stored for 2 weeks, 4 weeks, 6 weeks, and 8 weeks. The variables observed were the water and fat content, and the analysis of shelf life was carried out using the ASLT (Accelerated Shelf Life Test) method. The results showed that during storage, the water content increased, whereas the fat content decreased. Fat content is a critical variable in determining the shelf life of coffee. The coffee in AF130 packaging has longer shelf life than in AF65 and L144. To extend the shelf life of coffee packaged in AF130 and L144 is best kept at 45 oC whereas coffee in AF65 packaging  is ideally at 25 oC.
