Judul: Growth of Butterfly Pea Plant (Clitoria ternatea) on Different Media Composition and Shade Levels.
Abstrak: Bunga telang merupakan tanaman leguminosae yang dikenal memiliki bunga berwarna biru yang mengandung antosianin yang berkhasiat untuk manusia. Bunga telang dapat diolah menjadi minuman kesehatan, pewarna makanan, hingga menjadi tanaman obat. Bunga telang dapat tumbuh pada berbagai kondisi yaitu pada kondisi dataran tinggi maupun dataran rendah. Banyaknya manfaat yang dimiliki bunga telang maka diperlukan penelitian untuk mengetahui cara memproduksi tanaman dengan hasil yang terbaik. Penelitian bertujuan mempelajari respon pertumbuhan dan hasil produksi bunga pada kondisi taraf naungan dan komposisi yang berbeda. Penelitian dilakukan di Kebun percobaan Leuwikopo, Kecamatan Dramaga, Kabupaten Bogor. Percobaan dilaksanakan dengan rancangan kelompok lengkap teracak (RKLT) faktorial dua faktor, yaitu naungan (55% dan 0%) dan Komposisi media tanah, campuran tanah dan pupuk kandang, dan campuran tanah, pupuk kandang, dan pasir) dengan 10 ulangan. Tanaman diperbanyak dengan biji dan ditanam pada polybag, Hasil penelitian menunjukkan bahwa tanaman dengan kondisi ternaungi dan komposisi tanah dengan pupuk kandang menghasilkan berbeda nyata tertinggi pada tinggi tanaman sebesar 147,99 cm pada kombinasi dan campuran tanah, pupuk kandang, dan pasir di bawah naungan 55% dan bobot bunga sebesar 0,38 g pada kombinasi campuran tanah dan pupuk kandang di bawah naungan 55%. Pemberian naungan menghasilkan respon berbeda nyata pada kadar antosianin total terbanyak sebesar 2,120 mg/100 g pada kombinasi campuran tanah dan pupuk kandang di bawah naungan 55%. Interaksi antara naungan dan media berpengaruh nyata pada tinggi tanaman, bobot bunga dan waktu berbunga., The butterfly pea plant is leguminosae that are known for its blue flower color which contains anthocyanins and antioxidants which are good for humans. The butterfly pea plant is widely used as a health drink, food coloring, and is used as a medicinal plant. Butterfly pea plants can grow in various conditions, namely in the highlands and lowlands. There are many benefits contained in the butterfly pea flower, so research is needed to find out how to produce plants with the best results. The aim of this research was to study the growth response and yield of flower production under different conditions of light intensity and media composition. The experiment was carried out at the Leuwikopo Experimental Station, Dramaga District, Bogor Regency. The research experimental design used a randomized complete group design (RKLT) factorial with two factors, namely shade (no shade and 55% shade) and media compositon (soil medium, mixed soil media and manure, and mixed soil media, manure and sand) with 10 replicates. Plants were propagated by seeds and planted in polybags. The results showed that plants with shaded conditions and a mixture of soil media with manure gave the best results for plant height which produced the highest plants at 147.99 cm on combination soil, manure and sand had the heaviest flower weights at 0.38 g on combination soil and manure. Shading gave the best response to a total anthocyanin level of 2.120 mg on combination soil and mananure and also have the darker color of flower petals. The interaction between shade and media affects plant height, flower weight and flowering time.

Abstrak: Penelitian ini dilakukan untuk mendapatkan dosis BAP yang terbaik dan menganalisis tingkat toleransi masam pada tanaman kembang telang (Clitoria ternatea) terhadap cekaman masam dengan level yang berbeda melalui teknik kultur jaringan. Penelitian ini didesain menjadi 2 penelitian. Penelitian 1: Dosis terbaik BAP pada tanaman kembang telang, II: Respon tanaman kembang telang berdasarkan cekaman masam. Penelitian I didesain menggunakan rancangan acak lengkap (RAL) dengan 5 perlakuan penambahan dosis BAP yang berbeda dengan ulangan yang tidak sama, terdiri dari (P0 (0 ppm BAP), P1 (0,5 ppm), P2 (1 ppm), P3 (1,5 ppm), dan P4 (2 ppm). Penelitian II didesain menggunakan rancangan acak lengkap (RAL) dengan 6 perlakuan penambahan level AlCl3 yang berbeda dengan ulangan tidak sama, terdiri dari (P0 (0 ppm AlCl3), P1 (100 ppm AlCl3), P2 (200 ppm AlCl3), P3 (300 ppm AlCl3), P4 (400 ppm AlCl3), dan P5 (500 ppm AlCl3)). Data dianalisis menggunakan analisis deskriptif dan analisis varian (ANOVA), jika ada signifikansi akan diuji lanjut menggunakan uji Duncan. Peubah yang diamati adalah pertambahan tinggi tanaman, jumlah daun, jumlah ranting, jumlah anakan, kelayuan daun, penyusutan media, pertambahan bobot tanaman, warna daun, dan perubahan pH media. Hasil penelitian menunjukan bahwa pemberian dosis BAP 0,5 ppm berpengaruh nyata terhadap tinggi tanaman dan bobot tanaman. Level dosis pemberian BAP terbaik pada tanaman kembang telang adalah level 0,5 ppm. penambahan AlCl3 dengan level lebih dari 300 ppm berpengaruh nyata menurunkan pertumbuhan tanaman kembang telang terhadap pertambahan tinggi tanaman, perubahan pH media, jumlah ranting, jumlah anakan, kelayuan daun, bobot tanaman dan susut media, namun tidak berpengaruh nyata terhadap jumlah daun. Tingkat toleransi tanaman kembang telang terhadap cekaman masam adalah level ≤ 300 ppm (pH 3,73)., This study was conducted to get the best dose of Bap and to analized the level of tolerance butterfly pea (Clitoria ternatea) plants to stress acidity at different levels through tissue culture technique. The study was designed as 2 studies. Research I: the best BAP dose of the butterfly pea plant, II: response of butterfly pea plant based on acidity stress. Research I was designed used a complete randomized design with the the different level BAP addition with the different number of replications (P0 (0 ppm BAP), P1 (0,5 ppm), P2 (1 ppm), P3 (1,5 ppm), dan P4 (2 ppm). Research II was designed used a complete randomized design with 6 treatments with the different level of AlCl3 addition with the different number of replications (P0 (0 ppm AlCl3), P1 (100 ppm AlCl3), P2 (200 ppm AlCl3), P3 (300 ppm AlCl3), P4 (400 ppm AlCl3), dan P5 (500 ppm AlCl3)). Data were analyzed using analysis of variance (ANOVA) and if there was significant difference, data were further analyzed using Duncan’s multiple range test. The variables observed were plant height increasing, number of leaves, number of branches, number of shoots multiplication, percentage of leaf withering, media depreciation, increased of plant weight, leaf color, and acidity media changes. The results showed that adding the dose level of 0,5 ppm BAP had a significant effect of increased plant height and plant weight. The effective level of adding BAP to butterfly pea plant is level 0,5

Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
