Abstract

Jatropha is an alternative resource of sustainable energi. Therefore, to support the use of sustainable energi,an increase production of Jatropha seed is important. As Jatropha seeds (fruits) only growth at terminal andaxial bud, therefore the presence of lateral bud is necessary to increase production of Jatropha seed.Formation of lateral bud is affected by the balance between auxin and sitokinin. Defoliation will control thebalance of these two hormone. In this study, defoliation is conducted on seedling at the age of 4 month.Each treatment was replicated    7 times. Variabel were observed and ended after 6 month. Result indicatecthat either defoliation will stimulated the formation and growth of lateral bud.

Abstract

Bunga Krisan (Chrysanthemum sp) merupakan salah satu jenis bunga potong yang popular dan banyak diminati oleh konsumen karena bentuk dan warnanya yang menarik serta ukuran yang bervariasi. Budidaya bunga krisan di Desa Ngasem merupakan mata pencaharian vital bagi petani karena sebagian besar bertanam bunga krisan. Permasalahan dalam budidaya bunga krisan potong yaitu penanganan pascapanen. Bunga yang dipotong, lama kesegarannya berkurang seiring menurunnya kandungan unsur hara dalam tanaman. Petani di Desa Ngasem mempertahankan kesegaran bunga potong krisan hanya direndam dalam air. Penelitian ini bertujuan untuk mengetahui cara penanganan pascapanen bunga potong krisan di Desa Ngasem dan mengetahui pengaruh pemberian vitamin C dalam larutan perendam (pulsing) sehingga dapat memperpanjang lama kesegaran bunga potong krisan. Perlakuan dalam percobaan adalah perbedaan komposisi larutan perendam bunga potong krisan, yaitu perlakuan P0 : larutan perendam berupa air 500 ml; perlakuan P1 : larutan perendam berupa campuran air 500 ml  dan  vitamin  C 100 ppm; perlakuan P2 : larutan perendam berupa campuan air 500 ml dan  vitamin  C 200 ppm. Masing-masing perlakuan diulang sebanyak 3 kali dengan rancangan percobaan berupa Rancangan Acak Lengkap (RAL) dengan pola faktor tunggal.. Parameter yang diamati yaitu lama kesegaran bunga potong krisan. Berdasarkan uji F hasil pengamatan menunjukkan bahwa lama kesegaran bunga potong krisan tidak dipengaruhi oleh pemberian vitamin C dalam larutan perendam tetapi hanya dipengaruhi oleh air tanpa pemberian vitamin C. Perlakuan air sebagai kontrol (perlakuan P0) mampu mempertahankan lama kesegaran bunga potong krisan tertinggi, yaitu 14 hari. Perlakuan dengan pemberian vitamin C (P1 dan P2) hanya mampu mempertahankan lama kesegaran bunga potong krisan selama 12 hari.

Abstract

Patchouly is one of the plants that produce essential oil, i.e. patchouly oil, which is commonl  used in cosmetic industry. Increasing the biomass of patchouly plants by triggering the growth could be one way to increase the production of pathouly oil. Therefore, the purpose of this research is to study the effect of apical bud cutting towards patchouly growth, and also to understand the optimum location of cutting on the nodus. The research used Complete Random Design method with 5 repetitions. There were 3 locations of cutting (R), i.e. R0 (without cutting), R1 (cutting at the first nodus), R2 (cutting at the second nodus). The observed variables are length and amount of lateral bud, wet weight, and dried weight. The data were then analysed using ANOVA with significancy level of 95%. If there were real different, the analysis were then continued using Duncan test with significancy level of 95%. The results showed that apical bud cutting gives real effect to the variable of length and amount of lateral bud. The untreated plant has the most lateral bud shorter than the treated ones. For the variables of wet and dried weight there were not any significant differents. Generally, cutting at the first nodus (R1) of patchouli plant gives better result than any other treatments.

Abstract

Aquaculture is one of important economic activity in Indonesia. The main problem in aquaculture is the low water quality such lower oxygen level . Ceratophyllum demersum is one of aquatic plants that is hypothesized capable in increasing oxygen level through photosynthesis. However the growth of C. demersum it self will consume oxygen from the water  through respiration. The aim of this study is to measure oxygen production and consumption by C. demersum at different density level. From this data, we will understand the potency of  C.demersum as bioaerator to supplay oxygen in the water. This experiment was designed using Completed Randomized Designed (CRD). Three density level of C. demersum was apllied as treatment. They were 100g/100L, 200g/100L dan 300g/100L. Each treatment was replicated by 4 times. Results indicated that in density of 300g/100L produced the highest oxygen level ( 1,65 ppm). The highest growth rate of C. demersum was resulted by density level of 200g/100L.

Abstract

Ascorbic acid and carotenoid are secondary metabolites found in roselle, which show antioxidant activity. These compounds can be obtained from callus induced  by several kinds of explants. The aims of this experiment is to study callus growth from explants which can encourage high level of antioxidant compounds. The callus was obtained from difference organ, i.e. section of leaf, petiole and flower sepal. Sterilized explants were planted in MS (Murashige&Skoog) combined with 2 mg/L Naphtalene Acetic Acid (NAA) dan 5 mg/L Benzyl Adenin (BA).  This experiment has been conducted by completly randomized design with 5 replicates. Besides fresh weight callus, callus respons from each explants were analyzed descrptively.  Ascorbic acid and carotenoid content were analyzed qualitatively and quantitatively by titration and spectrophotometric respectively.  The results showed that all kinds of explant dedifferentiated into callus which antioxidant content. Callus from leaf section had the higgest fresh weight with high level ascorbic acid. Whereas the higgest carotenoid level was obtained from callus-derived flower sepals. It conclused that  in vitro callus was useful for producing plant biochemical compounds. Keywords : Callus induction, antioxidant agents, explants, ascorbic acid, cartenoid

Abstract

Chlorophyll is a pigment of photosynthesis which is also efficacious as a cure for brain, lung, and oral cancer, and can be used as a disinfectant, antibiotic and dietary supplement, while carotenoids are useful as antioxidants. The content of the two pigments is strongly influenced by the age of the plant, especially for vegetable crops used in leaves such as cowpea (Vigna unguiculata (L.) Walp.). The purpose of this research is to know the pattern of chlorophyll content and carotenoid of cowpea leaf during the growth phase and to know the age of the right plant for harvesting cowpea so that the highest chlorophyll and carotenoid content is obtained. Cowpea seeds obtained from seeds are added then planted in pots containing ready-made planting media in the greenhouse. Chlorophyll and carotenoid analyzes were performed at different plant ages from 1 to 11 weeks. The research design used is Completely Randomized Design. Data were analyzed using variance analysis and continued with Duncan test at 95% significance level. The results showed that the highest chlorophyll and carotenoid content was produced by the cowpea leaf in the vegetative phase or before the flowering time. The highest chlorophyll content was obtained at 4WAP (weeks after planting) of age crop, while the highest carotenoid content was obtained in 3WAP.

Abstract

Red okra fruit has high nutritional value and fiber but still has low production. Monosodium glutamate (MSG) consists of sodium and glutamic acid. In plants, sodium can role of replacing potassium, stomata physiology, and chlorophyll biosynthesis. Glutamate as the nitrogen donor in primer metabolism and gibberellic acid precursor. The assumption that MSG in plants has a positive impact. This research aimed to examine the effect of MSG and the optimum dosage for enhances of growth and production. This research was conducted with Completely Randomized Designs (CRD) with one factor, is the MSG dosage (0, 3, 6, and 9 g). Quantitative data were analyzed using analysis of variant (ANOVA) dan Duncan’s Multiple Range Test (DMRT) at a 95% confidence level. The result shows that the MSG treatment enhances the growth of the okra based on parameters of plant’s height, fresh weight of plant, dry weight of plant and the width of the leaf and enhances the production of the okra based on the flowering time, the number of the flower, the number of the fruit, the percentage of flower becoming fruit, the weight of fruit, width of fruit, and the diameter of the fruit. The optimal dosage of MSG for okra production and growth is 3 g/plant.

Abstract

Germination and growth of orchid seeds can be accelerated by the addition of organic supplement and plant extract in culture medium. The objective of this study was to determine the effect of peptone and tomato extract on early stage of embryo development of Dendrobium phalaenopsis orchids. Orchid seeds were sown on NP and VW medium with addition of 10% of CW (NPCW and VWCW).  Five weeks after seed germination, about 58.03% seed germination was observed on VWCW medium, and only 37.45% seed germination on NPCW. Tomato extract and peptone were added in VWCW, resulting VWCWTP medium. After 4-8 weeks on VWCWTP, 94.42% seeds was germinated into plantlet, but only 67.30% germinated seeds on VWCW. To get optimal growth and development of  D.  phalaenopsis orchids embryos in the in vitro condition, supplement of 100 ml.L-1 coconut water, 100 mg.L-1 tomato extract and 2 mg.L-1 peptone into VW basic medium is required.
