Abstract

Pengembangan padi lokal saat ini masih kurang mendapat perhatian karena produktivitasnya masih tergolong rendah dibandingkan dengan padi sawah. Padahal, varietas lokal memiliki adaptasi kesesuaian yang tinggi terhadap daerah tertentu, varietas lokal juga perlu dipertahankan dan dilestarikan sebagai kekayaan plasma nutfah, sekaligus sumber keragaman genetik. Salah satu alternatif untuk meningkatkan pertumbuhan dan produktivitas padi lokal adalah dengan pengembangan teknologi penggunaan kompos. Tujuan dari penelitian ini adalah untuk mempelajari pertumbuhan dan produksi dua varietas padi lokal dengan pemberian beberapa komposisi kompos. Untuk itu dilakukan penelitian di Desa Paya Bakung Kec. Hamparan Perak, Kab. Deli Serdang dengan ketinggian tempat ± 25 meter di atas permukaan laut pada bulan Maret hingga September 2016.Penelitian ini dilakukan dengan menggunakan rancangan acak kelompok faktorial (RAK) dengan 2 faktor. Faktor pertama  adalah media tanam komposdengan 5 taraf yaitu: tanpa pemberian kompos (0 kg/plot) ;kompos blotong 3,6 kg/plot; kompos TKKS 3,6 kg/plot;  kompos blotong 3,6 kg/plot + kompos TKKS 3,6kg/plot; kompos blotong 7,2 kg/plot + kompos TKKS 3,6 kg/plot; kompos 3,6 kg/plot + kompos TKKS 7,2 kg/plot. Faktor II adalah varietas padi gogo, terdiri dari varietas  Sikembiri dan Sigendek-gendek. Hasil penelitian menunjukkan bahwa masing-masing varietas memiliki perbedaan tinggi tanaman sementaraperlakuan kompos nyata meningkatkan tinggi tanaman, dan jumlah anakan per rumpun. Kombinasi perlakuan media tanaman (blotong 7,2 kg/plot+TKKS 3,6 kg/plot)pada varietas Sikembiri dan Sigendek gendek menghasilkan rataaan tertinggi dari tinggi tanaman.

Abstract

ABSTRACT Response the seed germination of betel nut (Areca catechu L.) on some of scarification and gibberelic acid (GA3) concentration. The generative muliplication of betel nut need time to germinate about 8-12 weeks. One of causes is the ossify husk of seed which inhibit water into the seed. Therefore, a research had been conducted at Rumah Kassa, Faculty of Agriculture, USU (± 25 m asl) from March until May 2012 using factorial randomized block design with 2 (two) factors, i.e. scarification (without scarification, base scarification, middle scarification, and tip scarification) and gibberelic acid (GA3) concentration (0, 100, 200, and 300 mg/l). The parameters observed were speed of germination, seedling length, root length root number and leaf number. The result showed that scarification significantly increased on parameter speed of germination up to 64% and leaf number up to 167%. The gibberelic acid (GA3) concentration and interaction between scarification and gibberelic acid (GA3) concentration did not significant on all parameters.   Keywords: Betel Nut, Germination, Scarification, Gibberelic Acid (GA3)   ABSTRAK Respons perkecambahan benih pinang (Areca catechu L.) terhadap berbagai skarifikasi dan konsentrasi asam giberelat (GA3). Perbanyakan pinang secara generatif memerlukan waktu untuk proses perkecambahannya yaitu 8-12 minggu, salah satu penyebabnya adalah adanya dormansi yang disebabkan oleh kulit biji yang keras yang menghambat masuknya air ke dalam biji. Untuk itu suatu penelitian telah dilakukan di Rumah Kasa Fakultas Pertanian USU  (± 25 m dpl) pada Maret-Mei 2012 menggunakan rancangan acak kelompok faktorial 2 faktor yaitu skarifikasi benih (tanpa skarifikasi, skarifikasi pangkal, skarifikasi perut, dan skarifikasi ujung) dan perendaman dengan asam giberelat (GA3) (0, 100, 200, dan 300 mg/l). Peubah amatan yang diamati adalah laju perkecambahan, panjang bibit, panjang akar, jumlah akar dan jumlah daun. Hasil penelitian menunjukkan perlakuan skarifikasi benih nyata meningkatkan laju perkecambahan benih hingga 64% dan jumlah daun hingga 167% dibandingkan tanpa perlakuan skarifikasi. Konsentrasi asam giberelat (GA3) dan interaksi antara skarifikasi dan konsentrasi asam giberelat (GA3) berpengaruh tidak nyata terhadap semua peubah amatan. Kata kunci: Pinang, perkecambahan, skarifikasi, Asam Giberelat (GA3)

Abstract

Tomato is one of the fruits that are beneficial to humans. Tomato has a delicious taste and has acomposition of substances in tomatoes quite complete and well. Composition in tomatoes quiteprominent of these is the composition of vitamin A and C. With vegetables like tomatoes and otherfruits, can be processed into various food products. Nutrient composition of tomato fruit is 100grams of protein (1 g), carbohydrate (4.2 g), fat (0.3 g), calcium (5 mg), phosphorus (27 mg), iron(0.5 mg ), vitamin A (carotene) 1500 SI, vitamin B (thiamine) 60 mcg, vitamin C 40 mg. Vitaminscontained in tomatoes is necessary for the growth and health of the body. Vitamin C is useful toprevent ulcers, to maintain healthy teeth and gums, as well as protect against other diseases causedby lack of vitamin C. Even the U.S. study showed, tomatoes can be used as a preventative ofcancer, particularly prostate cancer, if eaten on a regular basis as much as 5 pieces every week. Oneof the business in order to increase the levels of vitamin C in tomatoes that growth hormone GA3application. Results of research conducted by Meiriani (2011) on the provision of GA3 on tomatoplants results obtained highest levels of vitamin C at a concentration of 450 ppm with a frequencyof 3 times is equal to 123.20 mg/100 g. This research aimed to increase in vitamin C of tomato(Lycopersicum esculentum Mill.) with the hormone GA3. This research aimed to increase vitaminof tomato (Lycopersicum esculentum Mill.) with the GA3 hormone. This Research was conducted atthe Faculty of Agriculture, Universitas Sumatera Utara about + 25 meters above sea level fromJanuary to April 2012. And arrange in randomized block design with two-factors factorialtreatments. The first factor was concentration of GA3 with four levels : 300 ppm, 450 ppm, 600ppm, 750 ppm and the second factor was frequency of GA3 with three levels, i.e : 3 time, 4 timesand 5 times. The result of research showed that application of GA3 at concentration up to 750 ppmwas significantly influenced to increased tomato vitamin C level. Interaction of both treatmentwas not significant to influenced parameter of observation.Key words : GA3, tomato, consentration, application frequency, vitamin C.

The Application of Solid and Liquid Organic Fertilizer of Banana Kepok Bark on the Growth andYield of Mustard (Brassica juncea L.). The research aimed to know differences in growth responseand yield of mustard in various dose of solid and liquid organic fertilizer from banana kepok barkand the interaction of both factors. The research was carried out in the home screen, Agriculture’sFaculty of North Sumatera University from August to Oktober 2013. The experiment design wasFactorial Randomized Block design (FRB) with two factors and three replications. The first factorwas the solid organic fertilizer dose consist of four levels are 0 , 30 , 60 and 90 g/plant. The secondfactor was a liquid organic fertilizer dose are 0 , 25 , 45 and 65 ml/plant/application. The resultsshowed that the solid organic fertilizer give significant effect on lower the plant height 15 daysafter transplanting and the total of leaf area on 30 days after transplanting. The liquid organicfertilizer significant effect on lower plant height 11 , 19 , 23 , and 27 days after transplanting, dryweight of plant on 30 days after transplanting, the plant yield per sample and yield per plot on 40days after transplanting. The interaction of both significantly on parameter plant height 7 days aftertransplanting and the best result treatment is solid organic fertilizer 30 g/plant without liquidorganic fertilizer.Keywords: Solid Organic, Mustard, Bark of Banana

Abstract

Generally, propagation of shallot used bulbs as planting material. Cutting bulbs is one way todecrease the use of planting material. Cutting bulbs cause decreasing of growth point per plant. Bymore small plant spacing can balance growth point decreased, so that it can reach optimalproduction. This research was conducted at Jl. Pasar I No. 89 Tanjung Sari, Medan in Mei-August2013, using factorial randomized block design with two factor, i.e; cutting bulbs (no cutting bulbs,cutting 2 section, cutting 4 section) and plant spacing (10x15, 15x15 and 20x15 cm). Parameterobserved were plant height, number of leaves per plant, number of tillers per plant and dry bulbweight per plot. The result of the research showed that no cutting bulbs significantly increased onplant height, number of leaves per plant, number of tillers per plant and dry bulb weight per plotwhich is higher than the other treatments. 10x15 cm plant spacing significantly increased on drybulb weight per plot which is higher than the other treatments. Interaction between two factor notsignificantly effected on all parameter observed.Key words: cutting bulbs, plant spacing, shallot
