Abstract

The objective of this research was to know the influence of organic fertilizer concentration from the wastes of kepok banana peels on the growth of mustard greens. The results of the study used as a source on the preparation of students worksheets. In this experiment, there are four treatments and six repetitions. Fertilizer concentration used were: 0, 20, 40, 60 mls/plant/application. Data were variety analyzed and BNT tested on the level of 5 %. The results of this research showed that liquid organic fertilizer of kepok banana peels influence very real on the growth of a mustard greens plant, which included the height of plant, number of leaves, and width of mustard greens leaves. The concentration of fertilizer that gives best result was the  liquid organic fertilizer from kepok banana peels 20 ml. The average value of student worksheets feasibility on XII class students of SMA was 3.46. Therefore the student worksheets were declared very reasonable used as a source of learning.Penelitian ini dimaksudkan untuk mengetahui pengaruh konsentrasi pupuk organik cair kulit buah pisang kepok terhadap pertumbuhan sawi. Hasil penelitian digunakan sebagai sumber materi penyusunan Lembar Kerja Siswa. Dalam penelitian  ini terdapat empat perlakuan dan enam pengulangan. Kosentrasi pupuk yang digunakan: 0, 20, 40, 60 ml/ tanaman/ aplikasi. Data dianalisis ragam dan diuji BNT pada taraf 5%.Hasil penelitian menunjukkan bahwa pemberian pupuk organik cair limbah kulit buah pisang berpengaruh sangat nyata terhadap pertumbuhan tanaman sawi yang meliputi tinggi tanaman, jumlah daun serta luas daun sawi.

Abstract

The objective of this research was to know effect of citric acid, aluminum, and their itsinteraction on the seedling growth of hibrida maize (Zea mays L.) Var. Bisi-18. Theexperiment was conducted during January 2016 in Plant Physiology Laboratory,Department of Biology, Faculty of Mathematics and Natural Science, University ofLampung. The experiment was implemented in 2x3 factorial experiments. Factor A wasAluminum with 2 levels: 0 mM, 5 mM. Factor B was Citric Acid with 3 levels: 0 mM, 5 mM,and 10 mM. After selected corn seeds were soaked in citric acid solution for 24 hours, andgerminated in plastic tray. After 7 days seedlings were planted in plastic containers thatcontain aluminum solution. Variables in this research were shoot length, seedling freshweight, shoot root ratio, and relative water content after 7 days of growing period. Analysisof variance was conducted at 5% significant level. If interactions between aluminum andcitric acid was not significant, main effect was determined at 5% significant level with LSDtest. If interactions between aluminum and citric acid was significant, simple effect wasdetermined at 5% significant level with F test. The result showed that no aluminum effectobserved on all variables, and citric acid affected negativly all variables. No interctionsbetween aluminum and citric acid on all seedling growth variables of maize hibrida Var.Bisi-18. It is concluded aluminum 5mM was not able to cause stress in maize seedling. Inno stress condition citric acid has negative effect on maize seedling growth.Keyword: Citric acid, Aluminium, Maize Seedling, Shoot Length, Seedling Fresh Weight.

Abstract

The objective of this research was to know whether soaking of upland rice seed in citric acid solution  could  alleviate  subsequent  growth  of  seedling  under  aluminum  stress.  The experiment was conducted in plant physiologylaboratory, Department of Biology, Faculty of Mathematic and Natural Science, Lampung University on January 2016, and implemented in2 x 3 factorial designs. Factor A was aluminum with two levels: 0 mM, 5 mM and factor B was Citric Acid with three levels: 0Mm, 5Mm, 10Mm. Variables in this research were shoot length, seedling fresh weight, relative water content, and shoot root ratio. Analysis of variance was conducted at 5% significant level. If   interaction factor A and B was not significant, main effect was determine with lsd test at 5% significant level, but if  significant simple effect was determine with F test at 5% significant level. The result showed that interaction beetwen aluminum and citric acid decreased the shoot length 16-31%. Aluminum decreased fresh weight of seedling 11%, relative water content 3%, and shoot root ratio decreased 15%. It was concluded that soaking upland rice seed in citric acid solution was not able to alleviate subsequent growth of seedling under aluminum stress. Keyword: citric acid, aluminum, upland rice, shoot length, seedling fresh weight

Abstract

Tujuan dari penelitian ini adalah membuktikan bahwa pada fase awal pertumbuhan vegetatif padi gogo varietas Inpago 8 tahan terhadap alelopati dari ekstrak daun kering babandotan (Ageratum conyzoides L.). Penelitian ini dilakukan pada bulan November – Desember 2018 di Laboratorium Botani Jurusan Biologi Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas Lampung. Penelitian ini menggunakan metode RAL (Rancangan Acak Lengkap) dengan ekstrak daun kering babandotan sebagai faktor utamanyayang terdiri atas 5 taraf konsentrasi yaitu 0% b/v, 2,5% b/v, 5% b/v, 7,5% b/v, dan 10% b/v dan terdiri dari 5 kali ulangan. Parameter yang diukur dalam penelitian ini adalah daya kecambah, panjang tunas, berat segar, berat kering,kadar air relatif, dan kandungan klorofil a,b serta total kecambah. Homogenitas ragam ditentukan dengan uji Levene pada taraf nyata 5%. Analisis ragam dan uji BNJ dilakukan pada taraf nyata 5 %. Hasil penelitian ini menunjukkan bahwa ekstrak daun kering babandotan tidak bersifat alelopati terhadap perkecambahan benih padi gogo varietas Inpago 8. Pada konsentrasi 7,5% b/v menstimulasi pertumbuhan kecambah padi gogo Inpago 8 yang ditunjukkan oleh peningkatan panjang tunas dan berat segar tunas.
