Abstract

‘Diamond river’ is introduction plant that cultivated in Indonesian. Development of longan flower divided into eight stadium  during 28 days. First and second stadium is the induction phase that lasts for 8 days, this phase is characterized by a change in color of the leaves become older by using the Munsell color charts for plant tissues indicate the scale of 7.5 GY (4/4) to GY 7.5 scale (3\2). Third stadium is the phase of flower initiation occurred by day eigth. Initiation stage appearance were showed by merristem axilar, which will form part of primordial flower. Fourth to seventh stadium are phase that a differentiation occurred on day 12 to day 24. Differentiation phase showed the development in suitable with the typical angiosperms are sepals, stamens, petals and pistils. Eighth stadium is the phase of anthesis occurred on day 28. In the phase of anthesis, flowers have undergone a process of pollination and fertilization. Keywords: Development, Diamond river, Flowering, stadium

Abstract

Lengkeng (Dimocarpus longan Lour.) merupakan salah satu tanaman asli dari Asia Tenggara yang termasuk dalam famili Sapindaceae. Tujuan penelitian ini adalah mengetahui struktur anatomi daun lengkeng dan perbedaan antar ke empat kultivar tersebut. Penelitian ini menggunakan dua metode yaitu metode parafin (Suntoro, 1983) untuk preparat anatomi di Fakultas Biologi, UGM dan metode Johansen (1940) dilakukan untuk pembuatan preparat paradermal stomata di jurusan Biologi, FMIPA, Universitas Jember. Hasil menunjukkan bahwa struktur anatomi daun lengkeng terdapat perbedaan dalam hal ketebalannya. Nilai ketebalan daun tertinggi pada kultivar Pingpong dengan mesofil paling tebal diantara ketiga kultivar tersebut yaitu 174,04 μm, dan jaringan palisade yaitu 71,69 μm, epidermis atas yaitu 12,52 μm, kutikula yaitu 5,53 μm, serta mempunyai lengan trikoma paling panjang dengan nilai rata-rata 17,82 μm, Kultivar pingpong juga mempunyai nilai densitas stomata tertinggi di antara ketiga kultivar lainnya yaitu 20,38 mm2, tetapi mempunyai panjang stomata terendah yaitu 21,42 μm. Kata Kunci: Anatomi lengkeng, Dimocarpus longan,, densitas stomata.

Abstract

Induction of somatic embryogenesis in sugarcane requires the composition Plant Growth Hormone (PGH) appropriate. Utilizing of PGH (2,4-D and kinetin) is expected to induce sugarcane somatic embryogenesis. The purpose of this study was to obtain the concentration of 2,4-D and kinetin that effective for the multiplication of sugarcane var. NXI 1-3 through somatic embryogenesis. This study consists of four stages: callus induction, callus proliferation, regeneration of shoots and encapsulation. The plant material used is a spindle leaf sugarcane var. NXI 1-3. Callus induction used 2,4-D with different concentration (2 ppm, 3 ppm and 4 ppm). Callus proliferation used 2,4-D with concentration 1 ppm and 2 ppm. Regeneration of shoots used kinetin 0,5 ppm. The results are showed that the optimal induction of embryogenic callus on medium MS + sucrose 30 g / L + CH 300 ppm + 300 ppm PVP + 2,4-D 4 ppm as indicated by the high percentage of explants forming embryogenic callus that is equal to 40% and the respective concentration 2 ppm and 3 ppm is 33,3% and 37,5%. In proliferation stage, the development callus optimal on medium MS + sucrose 30 g / L + CH 300pm + PVP 300 ppm + 2,4-D 2 ppm and formulations for regeneration shoot on medium MS + sucrose 30 g / L + kinetin 0.5 ppm. The result of encapsulation can be shaped 100 sythetic seed. Keywords: Somatic embryogenesis, spindle leaf, kinetin, 2,4-D

Abstract

Phaeophyta merupakan salah satu kelompok makroalga yang tersebar melimpah di zona intertidal. Alga makrobentik ini memiliki struktur talus yang terdiri atas bagian holdfast, stipe, dan blade. Kelompok tersebut memiliki kandungan warna yang disebut pigmen fukosantin. Metode yang digunakan adalah road sampling dengan melakukan penyusuran seluruh area sampling menggunakan GPS (Global Positioning System). Jenis-jenis alga yang ditemukan diidentifikasi dan dideskripsikan secara morfologi. Analisis komposisi jenis dilakukan secara deskripsi kualitatif . Hasil yang diperoleh yaitu terdapat empat jenis Phaeophyta yang terdiri atas Sargassum sp., Padina australis, Spatoglossum sp., dan Turbinaria ornata. Jenis-jenis yang ditemukan umumnya memiliki karakteristik morfologi holdfastnya bentuk cakram dan lempeng, stipe pendek, serta blade berupa lembaran dan silindris.Kata Kunci: Pantai Pancur, Phaeophyta, Struktur Morfologi, Zona intertidal

Abstract

Dumortiera hirsuta is one of the liverworts that can be used as a medicinal to prevent infection by pathogenic bacteria. The content of secondary metabolites of D. hirsuta has potential as antibacterial properties includes flavonoids, alkaloids and steroids. This research is to analyze the antibacterial activity of moss D. hirsuta against pathogenic bacteria that will be beneficial to humans. Liverworts of D. hirsuta were extracted using ethyl acetate solvent and tested against three types of pathogenic bacteria using the agar well-diffusion method. The results of this study indicated that the ethyl acetate extract of D. hirsuta at 100% concentration could inhibit the growth of Escherichia coli, Staphylococcus aureus, and Salmonella typhi bacteria. The range of antibacterial activity categories of the ethyl acetate extract of D. hirsuta to E. coli, S. aureus, and S. typhi between weak to moderate.
