Abstract

Kopi Robusta diperbanyak secara klonal (vegetatif) melalui setek satu ruas. Pertumbuhan setek dipengaruhi oleh sumber bahan tanam (umur dan nomor ruas) dan faktor genetik. Penggunaan hormon alami dapat menjadi alternatif selain hormon berbahan dasar kimia. Penelitian dilaksanakan di Kebun Percobaan Pakuwon dan Laboratoriun Terpadu Balai Penelitian Tanaman Industri dan Penyegar, Sukabumi, Jawa Barat, mulai bulan September sampai dengan Desember 2020. Tujuan penelitian adalah untuk mengetahui respons pertumbuhan setek enam klon kopi Robusta akibat dari perbedaan perlakuan nomor ruas dan hormon tumbuh yang digunakan. Penelitian menggunakan rancangan split split plot dengan dua ulangan. Petak utama adalah enam jenis klon kopi Robusta (BP 308, BP 913, BP 436, SA 237, BP 358, dan BP 936), anak petak adalah tiga jenis hormon: Root-Up 5%, ekstrak bawang merah 100%, dan pasta bawang merah, dan anak anak petak adalah nomor ruas entres (1, 2, 3, dan 4). Peubah yang diamati meliputi: tinggi tunas per setek, jumlah tunas per setek, jumlah ruas per setek, jumlah daun per setek, panjang akar primer, jumlah akar primer, dan persentase setek hidup. Hasil penelitian menunjukkan tidak terdapat interaksi antara jenis klon, jenis hormon, dan nomor ruas. BP 308 memiliki panjang akar primer dan jumlah akar primer tertinggi dibandingkan dengan klon lainnya. Zat pengatur tumbuh kimia merangsang pertumbuhan tunas, jumlah akar, dan jumlah daun lebih tinggi dari larutan  ekstrak dan pasta bawang. Nomor ruas berpengaruh nyata terhadap jumlah tunas dan panjang akar. Interaksi klon dengan nomor ruas memengaruhi tinggi tunas, jumlah akar primer, dan persentase hidup setek.

Abstract

Recommendation of Robusta coffee fertilizer that available until now is only in general. In fact, the type and amount of fertilizer needed is highly dependent on environmental conditions, clones, and plant age. The study aimed to investigate the effect of combination doses of urea, SP36, and KCl fertilizer on growth, yield, and bean quality of four Robusta coffee clones cultivated in red-yellow podzolic soil type (PMK), North Lampung. The study was conducted at KP. Cahaya Negeri, North Lampung, with the altitude of 250 m above sea level, PMK soil type and climate type of C (Oldemand), from October 2011 to June 2014. The research was arranged in split plot design with four replications. The main plot was four Robusta coffee clones i.e. (K1) = BP 42; (K2) = BP 409; (K3) = BP 936; and (K4) = BP 939, while the subplot was four combination doses of urea, SP36, and KCl i.e. (P1) = 30:20:20 g/tree; (P2) = 40:30:30 g/tree; (P3) = 50:40:40 g/tree; and (P4) = 60:50:50 g/tree. The results showed that four Robusta coffee clones (BP 42, BP 409, BP 936, and BP 939) cultivated in PMK soil type, KP. Cahaya Negeri, North Lampung, had the same response to combination doses of urea, SP36 and KCl fertilizer. The combination doses of urea, SP36, and KCl of 50, 40, and 40 g/tree, respectively were optimal and efficient for growth and yield of those four clones until 2.5 years old. However, the dose has not yet been able to improve the quality of coffee beans.

Abstract

Morphological characterization of superior Robusta coffee plants has been widely studied, but for the anatomical and physiological character is still relatively limited. Result of this characterization is important as a basic information in order to create the new superior varieties. The purpose of this study was to investigate the morphological, anatomical, and physiological characteristics of seven clones of Robusta coffee (SA 203, BP 534, BP 42, BP 409, BP 939, BP 308 and BP 436). The experiment was conducted at Pakuwon Experimental Station and Integrated Laboratory of Indonesian Industrial and Beverage Crops Research Institute, Sukabumi, West Java, from October to November 2019.  The Completely Randomized Design with 7 Robusta coffee clones as treatments and three replications was used in this study. The variable observed were morphological (leaf area), anatomical (stomata shape and density) and physiological characters (chlorophyll a, chlorophyll b and total chlorophyll). The results showed that the leaf area of the first and third leaves of seven clones of Robusta coffee were relatively uniform. The stomata shape of Robusta coffee leaf is parasitic type (Rubiaceous) type. The SA 203 and BP 409 clones have the fewest stomata contents. The content of chlorophyll a, b, and total in the first and third leaves varies between clones. Chlorophyll content in the basal, middle, and apical leaf were relatively uniform, except clones SA 203 and BP 939 for the first leaf, and SA 203 and BP 436 for third leaf. The correlation analysis showed a positive relationship between leaf area and chlorophyll content.

Abstract

Salah satu faktor yang mempengaruhi pertumbuhan dan produksi kopi adalah intensitas cahaya. Intensitas cahaya berhubungan dengan jenis naungan yang digunakan. Tujuan penelitian adalah mengevaluasi pengaruh berbagai jenis tanaman penaung terhadap pertumbuhan dan produksi kopi Arabika. Penelitian dilaksanakan di Kebun Percobaan (KP) Pakuwon, Balai Penelitian Tanaman Industri dan Penyegar Sukabumi dari bulan Februari sampai dengan Desember 2011. Rancangan penelitian yang digunakan adalah acak lengkap dengan 6 ulangan. Perlakuan yang diuji adalah jenis pohon penaung, yaitu: (1) ceremai, (2) belimbing wuluh, (3) kayumanis, dan (4) gliricidia. Pengamatan dilakukan  terhadap parameter tinggi tanaman, jumlah buku cabang primer, jumlah cabang primer, diameter batang, diameter tajuk, jarak antar cabang, dan persentase tanaman berbuah. Hasil penelitian menunjukkan bahwa gliricidia merupakan jenis tanaman penaung yang cocok bagi pertumbuhan dan persentase pembuahan tanaman kopi Arabika varietas Kartika 1 di KP Pakuwon.  Effect of Various of Shading Plant on Growth And Percentage Of Fruiting of Arabica Coffee Variety Kartika 1 ABSTRACT One of many factors that affects to growth and yields of coffee is light intensity. Light intensity will vary with type of shading trees used. The objective of this study was to find out a suitable shading trees for coffea growth and production . The study was carried at The Indonesian Research Institute for Industrial and Beverages Crops (IRIIBC), Sukabumi from Pebruary until December 2011. A randomized complete design with six replications was used in this study. Planting material used in this study was Arabica Coffee (var. Kartika 1) grown under 4 different shading trees tested for their suitability for coffe growing. The shading trees of coffee examined were: (1) Otaheite gooseberry, (2) Bilimbi, (3) Cassiavera, and (4) Gliricidia. Observations made were plant height, number of primary branches internodes, primary branch number, stem diameter, canopy diameter, distance between branches, and percentage of fruiting set. Result showed that Gliricidia was the most suitable of shading trees for growth and fruiting set of arabica coffea variety Kartika 1. Keywords :

Abstract

Sakiroh S, Sasmita KD, Astutik, D. 2021. The impact of shade and altitude on tea shoots production (Camellia sinensis L.). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 209-218. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Tea plants are tropical and subtropical C3 plants. The increasing worldwide demand for tea has a significant impact on Indonesian tea demand. Tea production was observed with the application of appropriate technical culture. Tea plant production and productivity can be raised and maximized by considering the plant's physical and environmental characteristics. Shade plants have an impact on the tea plant's environments. Temporary shade plants include Crotalaria sp. and Tephrosia sp., whereas permanent shade plants contain Grevillea robusta. Temporary shade plants are those that are currently developing and require a light intensity of 65-70 percent to grow. When compared to not applying shade in the tea planting technique, shade can improve tea growth. Shades can offer several benefits, including lowering the temperature, increasing humidity, reducing light intensity of the leaves' surface, and lessening the effect of photoinhibition, Both of these factors would have a long-term impact on tea productivity. Upper leaves with shade had a 65 percent higher photosynthetic rate than leaves without shade. In both the dry and wet seasons, the productivity and production of shaded tea are higher than that of un-shaded tea. Tea productivity in the highlands is higher than tea productivity in the middle and lower regions.
