Abstract

The purpose of this research was to know whether kirinyuh leaf water extract could improve the growth of mekongga varieties rice paddy under the condition of drought stress.This research was conducted at Botanical Laboratory of Biology Department Faculty of Mathematics and Natural Sciences University of Lampung from September to October 2017. The research was conducted in a 3 x 2 factorial experiment. Factor A was Polyethylene glicol 6000 with 3 levels of concentration: 0% w / v, 15% w / v, and 30% w / v. Factor B was kirinyuh leaf water extract with 2 concentration levels: 0% w / v and 2% w / v. As parameters were the mean of shoots length, fresh weight, dry weight, and the relative water content of rice seedling. Levene test, analysis of vaiance, and Tukey test were performed at 5% significant level. The results showed that water extract of kirinyuh leaves had no significant effect on shoot length, fresh weight, and dry weight of rice seedling, but influenced the relatife water content of rice seedling. From the result of research it was concluded that kirinyuh leaf water extract can not improve the growth of Mekongga rice paddy varieties at drougth stress condition

Abstract

The purpose of this research is to know whether the aqueous extract of mango leaves(Mangifera indica L.) affect the growth of purple nutsedge (Cyperus rotundus L.). Thisresearch conducted at Botanical Laboratory of Biology Department Faculty of Mathematicsand the Natural Sciences University of Lampung from September to October 2017. Thisexperiments were carried out in a complete randomized design with the main factors beingaqueous extract of mango leaves with 5 level concentration : 0% w / v ( control), 5% w / v,10% w / v, 15% w / v, and 20% w / v and consist of 5 replications. Parameters measuredwere shoot length, fresh weight, dry weight, and relative water content. The Levene testdetermined the homogeneity of variance at 5% significant level. Analysis of variance andTukey HSD testis did at 5% significant level. The results showed that the concentration ofextract was negatively correlated with shoot length where the shoot length was decreasedsignificantly at 20% extract concentration. Total fresh weight was decreased significantly at20% and correlated linearly negative with extract concentration. Total dry weight wasdecreased significantly at 20% extract concentration. There was no significant effect onrelative water content. From this research, it concluded that aqueous extract of mangoleaves at 20% extract concentration was decreased shoot length, fresh weight and dry weightof purple nutsedge.

Abstract

The purpose of this research is to know whether the aqueous extract of purple nutsedge(Cyperus rotundus) have an effect on the growth and chlorophyll content of upland riceseedling of Inpago 8 varieties. This research was conducted at Botanical Laboratory ofBiology Department Faculty of Mathematics and the Natural Sciences University ofLampung from September to October 2017. The experiments were carried out in a completerandomized design with the main factors being aqueous extract of purple nutsedge with 5 level : 0% v / v (control), 5% v / v, 10% v / v, 15% v / v, and 20%v/v. Parameters measuredwere shoot length, fresh weight, dry weight, relative water content, and total chlorophyllcontent of rice seedling. Homogeneity of variance was determined by the Levene test at 5%significant level. Analysis of variance and Tukey HSD test is done at 5% significant level.The results showed that the concentration of extract correlated quadratic with shoot lengthwhere the maximum shoot length was 3.9 cm at 10% extract concentration. Fresh weight andrelative water content maximum were 73.21 mg and 76% respectively at concentrations of14% and 10%. The minimum total chlorophyll content was 0.47 mg / g tissue at aconcentration of 11%. There was no significant effect on the dry weight of the seedling.From the results of the study, it was concluded that the extract of purple nutsedge at aconcentration below 14% was a growth stimulator, but it was an inhibitor of chlorophyllbiosynthesis.Keyword: Chlorophyll, Growth, Upland rice variety Inpago 8, Purple nutsedge

Abstract

Telah diteliti pengaruh ethrel terhadap kandungan karbohidrat terlarut total dan aktivitas dehidrogenase pada buah pisang Kepok (Musa paradisiaca L.). Penelitian ini dilaksanakan dalam percobaan faktorial 2x2. Faktor A adalah 2 taraf perlakuan yaitu kontrol dan ethrel. Faktor B adalah 2 tahap waktu pengukuran, yaitu 3 dan 6 hari setelah perlakuan. Karbohidrat terlarut total diukur dengan metoda fenol-sulfur dan absorbansi diukur dengan spektrofotometer pada 490 nm. Aktivitas dehidrogenase diukur dengan metode metilen blue, dan transmisi diukur dengan spektrofotometer pada 600 nm. Hubungan antara karbohidrat terlarut total dan aktivitas dehidrogenase ditentukan dengan regresi. Berdasarkan Analisis ragam pada taraf nyata 5% diperoleh bahwa ethrel tidak berpengaruh nyata terhadap kandungan karbohirat terlarut total. Kandungan karbohidrat terlarut total 6 hari setelah perlakuan lebih tinggi dari 3 hari setelah perlakuan. Tidak ada pengaruh ethrel terhadap aktivitas dehidrogenase pada buah pisang Kepok. Aktivitas dehidrogenase 6 hari setelah perlakuan lebih rendah dari 3 hari setelah perlakuan. Hubungan antara karbohidrat terlarut total dengan dehidrogenase bersifat kuadratik.

Abstract

Estimasi table ripe buah pisang Muli berdasarkan laju respirasi klimakterik dan uji iodine telah dilakukan pada bulan Maret 2013. Tujuan penelitian ini adalah untuk menentukan saat table ripe dari buah pisang muli terjadi. Penelitian ini menggunakan rancangan acak lengkap dengan 7 tahap pematangan buah pisang Muli sebagai perlakuan dan 4 ulangan. Laju respirasi diukur menggunakan respirometer. Karbohidrat terlarut total diukur menggunakan metode fenolsulfur dan absorbansi diukur menggunakan spektrofotometer dengan panjang gelombang 490 nm. Pati dideteksi dengan uji iodine. Gula pereduksi dideteksi dengan metode Benedict. Data dianalisis ragam pada taraf nyata 5 %. Hasil penelitian menunjukkan bahwa laju respirasi dan kandungan karbohidrat terlarut total tertinggi terjadi pada tahap 5. Tahap 1 dan tahap 2 mengandung banyak pati, sedangkan tahap 3, 4, dan 5 mengandung sedikit pati. Kandungan pati tidak ditemukan pada tahap 6 dan 7. Tidak ditemukan kandungan gula pereduksi pada tahap 1 dan tahap 2. Pada tahap 3 mengandung banyak gula pereduksi sedangkan tahap 4, 5, and 6 mengandung sedikit gula pereduksi. Tidak ditemukan kandungan gula pereduksi pada tahap 7. Pada tahap 5 kulit buah pisang muli didominasi warna kuning dengan sedikit warna hijau sehingga dapat disimpulkan bahwa table ripe buah pisang Muli terjadi pada tahap 5.

Abstract

Pengaruh ethrel terhadap laju respirasi dan kandungan klorofil buah jeruk nipis (Citrus aurantifolia Swingle) selama pematangan telah diteliti pada bulan Maret 2013. Penelitian ini dilaksanakan dalam rancangan acak lengkap. Perlakuan yang digunakan adalah larutan ethrel 0%, 5%, 10%, 15% and 20% dengan 5 pengulangan. Parameter yang diamati adalah rata-rata laju respirasi dan kandungan klorofil 4 dan 8 hari setelah perlakuan. Laju respirasi diukur dengan respirometer sederhana. Kandungan klorofil diukur dengan spektorfotometer (645 dan 663 nm). Analisis ragam dan uji BNT dilakukan pada taraf 5%. Hubungan antara laju respirasi dan kandungan klorofil ditentukan dengan regresi. Hasil penetlitian menunjukkan bahwa ethrel dengan konsentrasi 15% meningkatkan laju respirasi 4 hari setelah perlakuan sedangkan konsentrasi 10% meningkatkan laju respirasi 8 hari setelah perlakuan. Konsentrasi ethrel 15% menurunkan klorofil a dan total 4 hari setelah perlakuan sedangkan konsentrasi 10% menurunkan klorofil a, b dan total 8 hari setelah perlakuan. Konsentrasi ethrel 15% merupakan konsentrasi optimal untuk meningkatkan laju respirasi dan kandungan klorofil. Dari percobaan ini disimpulkan bahwa ethrel mempengaruhi laju respirasi dan kandungan klorofil buah jeruk nipis.
