Abstrak. Proses pembibitan kopi arabika memerlukan nutrisi yang baik dan berimbang dari dalam tanah. Namun, kondisi media pembibitan yang tidak seragam membuat pertumbuhan bibit kopi menjadi tidak seragam. Oleh karena itu diperlukan nutrisi tambahan berupa pupuk organik cair yang diaplikasikan melalui daun. Penelitian ini bertujuan untuk mengetahui kemampuan pupuk organik cair dalam menggantikan C-organik dan N-total Tanah, kemudian dihubungkan dengan pertumbuhan bibit kopi Arabika kultivar Lini S.795. Selain itu juga diharapkan diperoleh rekomendasi konsentrasi pupuk organik cair guna pembibitan kopi arabika. Percobaan dilaksanakan pada tanah Latosol dengan ketinggian tempat 675 meter di atas permukaan laut, memiliki pH 6,4, dengan kondisi curah hujan rata-rata 1963,50 mm/tahun. Metode penelitian yang digunakan adalah Rancangan Acak Kelompok (RAK) yang terdiri dari enam perlakuan dan empat ulangan. Adapun perlakuan konsentrasi pupuk organik cair (Pupuk Js): tanpa dipupuk (0 cc/L), Js1 0,5 ccl/L, Js2 1cc/L, Js3 1,5 cc/L, Js4 2 cc/L, dan Js5 2,5 cc/L. Hasil penelitian menunjukkan bahwa pemberian pupuk organik Js dengan konsentrasi 2 cc/L memberikan pengaruh yang lebih baik terhadap tinggi batang, jumlah daun, dan bobot kering tanaman. Namun tidak berpengaruh terhadap diameter batang bibit kopi arabika kultivar Lini S.795. Abstract. Breeding process of arabica coffee has requires good and balanced nutrition from the ground. However, the various condition of breeding media makes the growth of coffee seedlings was not uniform. Therefore we need additional nutrients from liquid organic fertilizer which is applied through the leaves. This study aims to determine the ability of liquid organic fertilizer in replacing soil organic-C and Total-N, then associated with the growth of arabica coffee seedlings Lini S. 795 cultivars. Nevertheless expected to obtain recommendations the concentration of liquid organic fertilizer for arabica coffee breeding. The experiment was carried out on Latosols with a heigth of 675 m above sea level, having 6,4 of pH, with an average rainfall condition of 1963,5 mm/ year. This research method was used a randomized block design consist of six treatments and four replications. The concentration of liquid organic fertilizer treatment (Js fertilizer): without fertilizing (0 cc/L), Js1 0,5 ccl/L, Js2 1cc/L, Js3 1,5 cc/L, Js4 2 cc/L, and Js5 2,5 cc/L. The results showed that the applications of Js2 with 2 cc/L of concentration had better effect on stem height, number of leaves, and plant dry weight. But had not effect to stem diameters of arabica coffee cultivar Lini S. 795 seedlings.

Potato plants are one of the supporting commodities for the food diversification program because they have a high protein content. In addition, the potato plant is a strategic commodity in the supply of foodstuffs to support food. The need for potatoes is increasing, due to population growth and increasing public awareness of nutrition and the widespread use of potato production for various foodstuffs, foodstuffs. The aim of this research is to effect of NPK dosage fertilizer (15:15:15) on growth and yield. potato (Solanum tuberosum L.) Granola variety and to get the NPK dosege fertilizer (15:15:15) which is the NPK dosege fertilizer (15:15: 15) which is obtained and the yield of potato (Solanum tuberosum L.) granola variety. The experiment was conducted in Sukamenak Village RT 007 RW 018 Pangalengan Village, Pangalengan District, Bandung Regency, West Java Province. With an altitude of 1,400 meters above sea level (m asl). Rainfall 2,844 mm/year including type C2 rainfall based on Oldeman's classification (1979). Andisol soil type with a pH of 6.8. The experiment was carried from September until December 2021. The research method used was a randomized block design (RBD) consisting of six treatments and four replications. NPK fertilizer dosage (15:15:15) treatments are as follows: A (0 kg/ha), B (800 kg/ha), C (900 kg/ha), D (1000 kg/ha), E (1100 kg/ha) and F (1200 kg/ha). The results showed that giving a dosege 800 kg/ha of NPK fertilizer (15:15:15) had a better effect on plant height, number of leaves and tuber weight per plot.

ABSTRACTThe aim of the study was to determine the appropriate age and number of seeds for the transfer process (Tapin) from the nursery to the planting area in order to obtain high growth and yield of black rice.This research was conducted in Lemah Duhur irrigated rice fields, Kiangroke Village, Banjaran District, Bandung Regency, West Java Province.This study used an experimental method with Split Plot Design using 2 factors, namely seed age (U) as the main plot consisting of 4 levels, namely u1 = 10 days after sowing, u2 = 15 days after sowing, u3 = 20 days after sowing scatter and u4 = 25 days after scatter. The number of seeds per planting hole (J) as child plots consisted of 4 levels, namely j1 = 1 seed per planting hole, j2 = 3 seeds per planting hole, j3 = 5 seeds per planting hole and j4 = 7 seeds per planting hole.Parameters observed were: number of tillers per clump, number of panicles per clump, weight of harvested dry unhulled (GKP) per clump, weight of dry harvested unhulled (GKP) per plot, weight of dry milled unhulled (GKG) per plot.The results showed that there was no interaction between the treatment of seed age and the number of seeds operted in the planting hole for all observation parameters. The highest average number of panicles per clump was found in u2j1, the highest average weight of harvested dry grain per clump was found in treatment u4j1, the highest average weight of harvested dry grain (GKP) per plot was found in treatment u4j1, the average the highest average weight of dry milled grain (GKG) per plot was in the u4j1 treatment. Key words : seed age, seed number, black rice, anthocyanin, aleurone
