Abstract

The frequent drought in Indonesia has caused many farmers to experience a decline in vegetable production, one of which is green mustard. The green mustard is not resistant to drought, so water supply is an aspect that must be given special attention in cultivating green mustard. The objective of this study was to know whether the seedling and growth of seedling of green mustard (Brassica juncea L.) can grow well under drought stress by Polyethylene glycol 6000. This study was conducted in the Laboratory of Plant Physiology, Department of Biology, Faculty of Mathematics and Natural Science, the University of Lampung in 2019. This study was conducted in a Completely Randomized Design with the main factor is Polyethylene glycol 6000 with three levels: 0% w/v, 10% w/v, 20% w/v, and 30% w/v. Each combination of treatments was repeated five times. The number of the experimental unit was 20. The observed variables in this study were the percentage of seed germination, length of leaf, the width of leaf, a,b chlorophyll content, and total chlorophyll content. The data was homogenize using the Levene test, then continued to analyze using ANOVA at a 5% significant level and proceed with HSD test significant level 5% to determine the differences between the treatment. The result showed that under drought stress by Polyethylene glycol 6000 started to affect green mustard seedling and growth of seedling at the level of PEG 6000 concentration 20% w/v while the number of leaves not affected. The conclusion was PEG 6000 gave a negative impact on the green mustard and the green mustard induced by PEG 6000 10% w/v more adaptive than PEG 6000 20 w/v.

Abstract

Anggrek memiliki nilai ekonomis yang tinggi sehingga sangat potensial untuk dibudidayakan. Jenis yang paling banyak diminati masyarakat adalah Dendrobium dan Phalaenopsis. Namun terdapat kendala utama yang dapat memengaruhi pertumbuhan anggrek yaitu infeksi virus. Jenis virus yang dilaporkan paling banyak menginfeksi adalah Odontoglossum ringspot virus (ORSV). Infeksi virus ini dapat menghambat pertumbuhan dan ketahanan tanaman, menurunkan kualitas bunga dan nilai estetika serta daya jual. Didapati pula gejala infeksi virus berupa mosaik, klorotik, streak, dan nekrosis. Salah satu upaya untuk mengatasi infeksi virus adalah dengan memanfaatkan mikoriza. Mikoriza yang dapat digunakan yaitu Rhizoctonia sp. Asosiasi mikoriza pada tumbuhan anggrek dapat memberikan pengaruh positif pada penyerapan nutrisi dan pertumbuhan inangnya, sehingga diharapkan dapat melindungi anggrek dari infeksi virus. Tujuan penelitian ini untuk mengetahui efek induksi Rhizoctonia pada karakter anatomi daun Phalaenopsis amabilis dan Dendrobium discolor yang diinfeksi ORSV dan mengetahui apakah terdapat perbedaan anatomi diantara kedua anggrek tersebut. Penelitian dilakukan di Laboratorium Botani Biologi FMIPA Unila dengan menggunakan Rancangan Acak lengkap Faktorial. Hasil dari penelitian ini adalah terdapat perbedaan ketebalan daun antara daun yang diinokulasi virus dan daun dengan perlakuan mikoriza. Daun anggrek dengan perlakuan mikoriza memiliki ketebalan tertinggi sedangkan yang terinfeksi virus memiliki ketebalan terendah.

Abstract

Anggrek sangat terkenal karena memiliki corak, bentuk, ukuran, dan warna bunga beranekaragam. Phalaenopsis dan Dendrobium termasuk jenis anggrek yang diminati sehingga produksinya perlu ditingkatkan secara kuantitas maupun kualitas. Adanya infeksi virus Odontoglossum ringspot pada anggrek menjadi salah satu kendala dalam budidaya anggrek. Odontoglossum ringspot virus (ORSV) merupakan virus yang banyak menginfeksi anggrek dan menimbulkan gejala pada bagian daun berupa mosaik, nekrosis, klorotik, kelayuan serta daun menggulung. Upaya pengendalian infeksi ORSV dapat memanfaatkan mikroorganisme, seperti Rhizoctonia yang akan berasosiasi dengan perakaran anggrek membentuk simbiosis mutualisme yang kemudian dapat menyediakan nutrisi bagi anggrek. Tujuan penelitian ini adalah untuk mempelajari respon anggrek Phalaenopsis amabilis dan Dendrobium discolor terinduksi Rhizoctonia terhadap infeksi ORSV. Penelitian dilaksanakan dengan Rancangan Acak Lengkap (RAL) faktorial menggunakan 6 perlakuan dan 4 ulangan. Hasil penelitian menunjukkan bahwa Phalaenopsis amabilis lebih rentan terinfeksi ORSV daripada Dendrobium discolor, dengan gejala yaitu daun mosaik, nekrotik, dan malformasi pada kisaran waktu 11 hari setelah inokulasi dengan Rhizoctonia . Hal ini mengindikasikan bahwa inokulasi Rhizoctonia pada Dendrobium discolor yang terinfeksi ORSV memberikan ketahanan yang lebih baik dibandingkan pada Phalaenopsis amabilis.

Abstract

Large red chili pepper (Capsicum annuum L.) has a fairly complete nutrition and economic value. The supply of large red chili in the country is considered low compared to its demand, that’s why we need to increase its production. Increasing production can be done by fertilizing using natural fertilizers is coconut water (Cocos nucifera L.) and administration of Growth Regulatory Substances (ZPT) is atonik. The purpose of this research is to determine the effect of coconut water and atonic to the growth of large red chilli pepper sprouts determine which consentration of coconut water and atonic that has the most effective effect to the growth of large chilli pepper. This research was conducted in October - November 2019 at the Botany Laboratory, Department of Biology, Faculty of Mathematics and Science, University of Lampung. This research was carried out using a 2x3 factorial design using young coconut water (a) with 3 levels of concentration ie 0% v / v (a1), 25% v / v (a2) and 50% v / v (a3) and atonic solution ( b) with 2 concentrations, namely 0% v / v (b1) and 10% v / v (b2). Data analysis is the data homogeneous first with the Levene test at 5% significance level. Data analysis using analysis of variance (Analysis Of Variance) ɑ = 5%. If the interaction between the two factors is real, then proceed with the determination of the simple effect of coconut water at each level of atonic concentration with the F test at 5% significance level. The results of this research shows that the use of atonic and coconut water effects the growth of large red chili plants, and the most effective concentration to the growth of large red chilli pepper plants is the combination of 0% coconut water + 10% atonic.

Abstract

Orchids have a high level of biodiversity, such as Dendrobium and Phalaenopsis, which are epiphytes. Dendrobium can adapt to the condition of where it lives while Phalaenopsis can grow in highlands and depends on sunlight and humidity. Virus infection has become one of the obstacles in cultivating Dendrobium and Phalaenopsis. Efforts to increase fitness and control in Dendrobium and Phalaenopsis cultivation can be done by inducing the plant’s fitness using a mycorrhiza, such as Ceratorhiza. A mycorrhiza is a form of mutualism between fungi and the plant’s root. This research is aimed to give information related to the utilization of Cerathoriza for inducing orchids to suppress Odontoglossum ringspot virus (ORSV) infection, giving it better growth. The research was done in February-March 2021 at Botany Laboratory University of Lampung. A completely randomized factorial design was used on two factors, kind of orchid and mycorrhiza treatment (M), virus (V), and mycorrhiza virus (MV). Variables examined in this research are the amount of living and dead roots and leaves. Data obtained is homogenized using Levene’s test and continued by ANOVA with the significance level of 5% and further testing using Tukey’s test with the significance level of 5%. From this research, it is known that interaction between Phalaenopsis and Dendrobium exists during virus and mycorrhiza administration. It is concluded that Phalaenopsis anabilis is more vulnerable than Dendrobium discolor.

Abstract

Lampung Indonesia is one of the provinces on the island of Sumatra, which has a flora conservation area located in Liwa Botanical Garden, West Lampung Regency. One of the flora species in the area with a high level of diversity is the orchid plant. The Dendrobium is the largest orchid species, where the public widely hunts this orchid for an economic reason due to the beauty of its various flower shapes and colors. Given the high level of human encroachment, this can threaten the existence of natural orchid plants, causing loss of their original habitat and causing the extinction of orchid species. Based on data in Liwa Botanical Garden, there has been no further identification of natural orchids as a plant conservation effort. To protect and immediately save these natural orchids, it is necessary to identify the Dendrobium orchid species based on the leaf morphological approach. This research will be conducted in April-September 2020. Observations of leaf morphology include leaf shape, leaf tip shape, leaf base shape, leaf edge, leaf reinforcement, leaf arrangement, leaf surface texture, leaf symmetry, and leaf sitting based on guidelines for ornamental plant characterization books. Observations as secondary data were added to the character of the pseudobulb shape and orchid habitat. Observations as secondary data were added on the habitat character of pseudobulbs and orchids. The implementation of this activity is still in the period of the Covid-19 pandemic, so most of the activities are carried out online. The coaching and training phase was conducted through internal virtual discussions on Tuesday, July 7, 2020, while the coaching phase was conducted through meetings or verbal communication via telephone groups and WhatsApp. Based on the evaluation data, it is known that there is an increase in knowledge and understanding of training participants by 21.64 points. The percentage increase in value before and after training is 34.72%. Orchid-related activities at Liwa Botanical Garden were never carried out, thus imparting knowledge to Liwa Botanical Garden technicians and workers on the development of natural orchid identification methods based on the morphological character in local natural resource conservation in the 4.0 industrial revolution era.

Abstract

Lactobacillus sp merupakan salah satu spesies yang sering digunakan sebagai probiotik, namun kelemahan dari bakteri tersebut adalah tidak toleran terhadap  pH rendah (asam), di cairan empedu, serta pada suhu yang tinggi. Bakteri probiotik harus tetap hidup sejak mereka dikonsumsi hingga menetap di usus. Hal ini sulit karena bakteri harus melewati pH asam ekstrim di saluran pencernaan. Tujuan dalam penelitian ini adalah meningkatkan viabilitas BAL dalam kondisi simulasi asam lambung (pH=2) dan garam empedu (ox bile 0,5%) yang diimobiliasi dengan zeolite-natrium alginat. Enkapsulasi bakteri probiotik adalah alternatif yang memberikan perlindungan bagi sel-sel hidup yang berada pada kondisi yang merugikan. Berdasarkan hasil uraian di atas maka bertujuan untuk meningkatkan jumlah kelangsungan hidup bakteri Lactobacillus sp dalam kondisi simulasi asam lambung dan garam empedu bakteri probiotik dengan menggunakan imobilisasi natrium alginat-zeolit serta mengetahui gen penghasil antibiotik pada bakteri asam laktat. Metode yang digunakan dalam imobilisasi bakteri adalah ekstrusi. Berdasarkan hasil penelitian maka dapat disimpulkan bahwan Imobilisasi dengan penyalut natrium alginate-zeolit mampu meningkatkan viabilitas bakteri asam laktat. Dalam kondisi simulasi lambung dan garam empedu. Bakteri asam laktat (BAL) menghasilkan bakteriosin yang dapat berfungsi untuk menghambat bakteri Gram positif dan Gram negatif  berasal dari gen penghasil antimikroba yaitu terdapat gen plantaricin, casseicin, acidocin, lactacin B, helviticin Kata Kunci : Imobilisasi,  Natrium Alginat, Bakteri Asam Laktat, Zeolit, Gen Antimikroba
