Genetic Relationship of Banana at Bandarlampung City Based on the Number of Chromosome and Genom Type

A banana was rank 4th as food consumed by the world community after rice, wheat, and corn. Identification and characterization were important steps to explore the potential and important value of this plant. This study aims to obtain the kinship profile of banana germplasm in Bandarlampung City based on the number of chromosomes and their genome types. Characterization of banana accession is done by observing the morphological characteristics referring to 15 characters from Simmonds and Shepherd with the expected score of genomic determinants modified by Silayoi and Camchalow. The results of dendrogram analysis showed that on a scale of 20-23 obtained 2 groups of banana accessions. The first group consisted of 7 accessions of bananas, namely Kepok Kapas, Kepok Manado, Kepok Kuning, Rabig, Kepok Batu, Raja Sajen, and Pisang Batu. The second group consisted of 15 accessions, namely Kepok Abu, Horn, Thousand, Janten, Mas Kuning, Mas, Muli, Rejang, Ambon Lumut, Papan, Cavendish, Ambon Kuning, Morosebo, Rajah Sereh, and Raja Nangka. Whereas 4 accessions, namely Ambon Australia, Kepok Lebanon, Kidang and Raja Bakar, could not be analyzed for their kinship because the data collection of the banana generative phase had passed or had not yet entered the generative phase. Whereas 1 accession, namely Musa ornate, is believed to be included in the Rhodhoclamys section so that the genome type cannot be determined. Based on group analysis obtained 2 large groups at a scale distance of 20-23. At a smaller scale distance of 10 obtained a subgroup with a large number of members

Potential of Pineapple Madu Shell (Ananas Comosus (L.) Merr.) as Anti-Browning Agent in Apples Manalagi (Malus Sylvestris Mill)

The purpose of this study was to determine the effect of water extract of pineapple shell in the process of browning apple manalagi (Malus sylvestris Mill). The research was conducted from October to November 2016 in the Laboratory of Plant Physiology Department of Biology, Faculty of Mathematics and Natural Sciences, University of Lampung. As variables were browning index, total soluble carbohydrate content, dehydrogenase enzyme activity, and reducing sugar levels, while the parameter is the mean of all variables. The experiment was conducted in completely randomizes design. The main factor was the water extract of the pineapple shell with 5 concentration levels: 0% v / v, 25% v / v, 50% v / v, 75% v / v, 100% v / v. Levene test, analysis of variance and LSD test was carried out at 5% significance level. The results showed that the water extract pineapple shell was significantly lower the browning index of apples manalagi, and the relationship between the concentration and browning index is quadratic (y = 9E-05x2 - 0.013x + 1.018 R² = 0665). Extract of pineapple shell did not significantly affect total soluble carbohydrate content of apples manalagi but a downward trend in total soluble carbohydrate content with increasing concentrations of the extract (y = -0.049x + 29.66 R² = 0.923). The relationship between the concentration of water extract pineapple shell with dehydrogenase enzyme activity was negative linear (y = -0.082x + 12.04 R² = 0.969). Reducing sugar levels increase at the concentration of 50% v/v,75% v/v, and 100% v/v. The final conclusion was that the water extract of pineapple shell was potential as anti-browning agent for apples manalagi because it was able to reduce browning index 51.89%, and influence other physiological processes

Metode Menghilangkan Cairan Buah Tomat dalam Uji Perkecambahan Biji Tomat( Lycopersicum Esculentum Mill.)

Budidaya tanaman tomat tidak terlepas dari ketersediaan bibit yang baik yang berasal dari biji yang berkualitas sebagai benih. Dalam penyediaan bibit di lapangan, petani tomat lebih senang menggunakan biji tomat dari toko-toko pertanian walaupun harganya lebih mahal dibandingkan dengan menyediakan sendiri. Penyediaan biji sendiri selain memerlukan waktu yang lebih lama juga daya perkecambahannya rendah karena di bagian luar biji tomat terdapat cairan buah yang dapat menghambat perkecambahan biji sehingga tidak menghasilkan bibit yang maksimal. Dengan demikian, perlu dicari metode yang tepat untuk menghilangkan cairan buah tomat pada biji. Penelitian ini dilaksanakan di Laboratorium Botani FMIPA Universitas Lampung, dari bulan Agustus- September 2012. Percobaan dirancang secara Acak Lengkap (RAL) dengan 8 perlakuan diulang sebanyak 4 kali. Parameter yang diukur adalah persentase perkecambahan dan kecepatan perkecambahan. Data yang diperoleh diuji homogenitas kemudian dilakukan uji ANARA dan dilanjutkan dengan uji lanjut Duncan pada taraf α = 5%. Hasil penelitian menunjukkan bahwa: metode yang tepat untuk menghilangkan cairan buah tomat yang menyelubungi biji tomat adalah dengan cara dicuci dan dikeringkan
