Abstract

Anggrek merupakan tanaman dengan nilai ekonomis tinggi. Pemeliharaan anggrek memerlukan peralatan dan ketrampilan khusus supaya dapat tumbuh dan berkembang dengan baik. Griya anggrek Mekar Sari merupakan salah satu rumah anggrek di wilayah Kalisegoro yang mempunyai potensi besar untuk berkembang. Pengembangan rumah anggrek ini terkendala adanya kurangnya sarana dan keterampilan pengelola dalam budidaya anggrek maupun pemasaran anggrek. Saat ini peralatan yang digunakan masih sangat terbatas. Selain itu pengadaan pupuk dan juga pembasmi hama juga masih terkendala oleh dana. Perawatan anggrek saat ini hanya berkisar penyiraman saja karena masih terbatasnya pengetahuan dan ketrampilan Ibu-Ibu PKK RW 4 Kalisegoro. Dukungan untuk mengatasi hal tersebut perlu adanya penyediaan alat dan bahan yang bekaitan dengan budidaya anggrek, pelatihan mengenai budidaya anggrek dan pelatihan pemasaran anggrek. Strategi pemasaran anggrek akan didukung dengan pembuatan web Griya Anggrek Mekar Sari sehingga Griya Anggrek Mekar Sari tidak hanya dikenal di sekitar lingkungan Kalisegoro tetapi juga daerah lain. Web Griya Mekar sari telah berhasil dikembangkan. Penambahan koleksi anggrek, peralatan dan juga bahan untuk pemeliharaan anggrek meningkatkan kualitas dan kuantitas anggrek. Peningkatan kualitas dan kuantitas anggrek serta adanya strategi pemasaran meningkatkan omzet penjualan anggrek.

Abstract

Penelitian ini menyelidiki respon fisiologis, anatomis, dan morfologis tanaman tembakau (Nicotiana tabacum L.) terhadap cekaman logam berat: tembaga (Cu), kadmium (Cd), dan timbal (Pb). Uji dilakukan pada bulan Januari-April 2014. Sampel yang digunakan adalah tembakau umur 3-4 minggu yang dikecambahkan secara in vitro dan kemudian dipapar logam berat selama 14 hari. Desain penelitian yang digunakan yaitu rancangan acak lengkap dengan satu faktor: yaitu konsentrasi logam Cu (0 µM, 50 µM, 100 µM, 150 µM & 200 µM), Cd (0 µM, 50 µM, 100 µM, 200 µM & 300 µM), dan Pb (0 µM, 5 µM, 20 µM, 50 µM & 100 µM). Parameter yang digunakan antara lain: pertambahan panjang akar, pertambahan jumlah akar, akumulasi logam dalam akar, lokalisasi penimbunan dalam akar, dan warna daun. Bertambahnya konsentrasi logam menghambat pertumbuhan akar dan menyebabkan deposit logam pada jaringan akar dan gejala klorosis. Hasil uji Atomic Absorbtion Spectrosphotometry (AAS) menunjukkan semakin besar konsentrasi semakin banyak akumulasi logam pada jaringan akar. Akumulasi Cd pada konsentrasi 200 µM lebih besar dibanding pada konsentrasi 300 µM. Hal ini menunjukkan ada faktor lain selain konsentrasi seperti respon internal individu dan gangguan permeabilitas. Analisis kualitatif membuktikan bahwa cekaman Cu tidak berpengaruh signifikan terhadap warna daun, sedangkan pada cekaman Cd (100, 150 dan 200 µM) dan Pb (150 µM) daun mengalami klorosis. Secara umum pengaruh konsentrasi logam berat yang rendah seperti 50 µM Cu, 50 µM Cd, dan 5 µM Pb terhadap parameter fisiologis, anatomis, dan morfologis tidak berbeda nyata pada taraf 5 % dengan kontrol. Dengan demikian dapat disimpulkan bahwa tembakau mampu mentoleransi cekaman logam pada konsentrasi yang rendah.This research investigated physiological, anatomical, and morphological responses of tobacco (Nicotiana tabacum L.) stressed by heavy metals: copper (Cu), cadmium (Cd), and lead (Pb).The experiment was conducted from January-April 2014. The samples used are three-four weeks tobaccos germinated by in vitro then were exposed to heavy metals for 14 days. This study used completed random design with single factor: concentrations of Cu (0 µM, 50 µM, 100 µM, 150 µM & 200 µM), Cd (0 µM, 50 µM, 100 µM, 200 µM & 300 µM), and Pb (0 µM, 5 µM, 20 µM, 50 µM & 100 µM. Further, stress response is analyzed based on several parameters includes root elongation, root number, metal accumulation and localization in root, and leaf color. The increased metals had caused growth inhibition, metal deposit in root tissue, and chlorosis symptoms. Atomic Absorption Spectrosphotometry (AAS) results showed that higher concentration will cause root tissue accumulate more metals. Yet 200 µM of Cd accumulated more than 300 µM Cd, so it could be suggested that there are other factors than concentration in determining metal absorbtion such as internal individual respon and membrane permeability disturbance. In other hand,qualitative analysis proved that chlorosis was not found in Cu treatment but consistently notified in high concentrations of Cd (100 µM up to 200 µM) and Pb (100 µM). However, the influence of lower metals concentration such as 50 µM Cu, 50 µM Cd and 5 µM Pband control treatment were not significantly different at the level of 5% in physiological, anatomical, and morphological responses. Therefore, it can be concluded that tobacco was capable to tolerate low concentration of metal stress.

Abstract

Koro benguk (Mucuna pruriens L.) adalah salah satu jenis kacang-kacangan lokal yang bisa digunakan sebagai pengganti kedelai dalam pembuatan tempe. Biji koro benguk merupakan sumber terbesar dari L-Dopa yang menjadi prekursor neurotransmitter digunakan untuk pengobatan penyakit Parkinson. Ekstraksi L-Dopa dalam skala besar membuat populasi Mucuna di alam bebas semakin terbatas. Sehingga, salah satu cara memperoleh bibit yang bermutu tinggi dapat dilakukan dengan perbanyakan tanaman secara in vitro. Penelitian ini bertujuan untuk menentukan respon dan konsentrasi BAP dan NAA yang optimum dalam kalogenesis eksplan setengah biji koro benguk. Rancangan dalam penelitian ini menggunakan rancangan acak lengkap pola faktorial 4x4 dengan perlakuan konsentrasi BAP (2, 3, 4, 5 ppm) dan NAA (0.2; 0,4; 0,6; 0,8 ppm) dengan dua ulangan. Parameter yang diamati adalah waktu inisiasi kalus, persentase eksplan yang berkalus, diameter kalus, warna dan tekstur kalus. Analisis data menggunakan anava dua arah dan uji lanjut Beda Nyata Terkecil. Hasil penelitian menunjukkan interaksi BAP dan NAA berpengaruh nyata terhadap waktu berkalus dan persentase berkalus, sedangkan konsentrasi NAA berpengaruh nyata terhadap diameter kalus eksplan setengah biji Mucuna pruriens. Kombinasi perlakuan yang direkomendasikan dalam penelitian kalogenesis ini adalah perlakuan BAP 2 ppm dan NAA 0,2 ppm karena kombinasi perlakuan tersebut memerlukan waktu berkalus paling pendek, memiliki persentase eksplan yang berkalus & diameter kalus paling besar, kalus berwarna hijau dan tekstur kalus yang friable. Mucuna puriens L. is one of the local leguminoceae which has many variety and used as a main material to substitute the soybean. The seed of M. pruriens are reported to contain L-3,4-dihydroxyphenylalanine (L-Dopa), a neurotransmitter precursor, used in the treatment of Parkinson’s disease. Large-scale extraction of L-Dopa from the wild populations of this plant has led to its limited availability in natural condition. Therefore, in vitro plant culture techniques may be an effective alternative for produce high quality seed. These objectives of this study are to determine the half-seed explants responses and the optimal concentration of BAP and NAA besides it also the interaction between them in caulogenesis. The experiment had been conducted by using 16 combination of BAP (2, 3, 4, 5 ppm) and NAA (0.2; 0,4; 0,6; 0,8 ppm) with Completely Randomized Design (CRD) in 4x4 factorial pattern by two replicates. The emerging of callus, the percentage, callus diameter, color and textur of the callus were the indicators observed. Collected data were analyzed using anova and followed by Least Significance Difference (LSD) (α=5%). The result of this research showed that the interaction of BAP and NAA affect in callus growth process (growth process and growth percentage) on half seed explant of Mucuna pruriens, meanwhile the concentration of NAA affect in the size of callus diameter. Combination treatment recommended in this research were BAP 2 ppm and NAA 0,2 ppm.
