Abstract

Abstrak : Tanaman miana saat ini dimanfaatkan sebagai tanaman hias. Perbanyakan Tanaman miana dapat dilakukan dengan cara generatif maupun vegetatif. Stek pucuk merupakan cara perbanyakan vegetatif tanaman miana yang relatif mudah dilakukan. Pembibitan dengan cara ini merupakan salah satu cara cepat dalam memenuhi kebutuhan bahan tanaman skala besar. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian Zat Pengatur Tumbuh terhadap stek pucuk tanaman miana (Coleus atropurpureus (L.) Benth. Penelitian dilaksanakan di di laboratorium agroekologi, Fakultas Pertanian, Universitas Sultan Ageng Tirtyasa. Penelitian akan dilaksanakan pada bulan pada bulan Maret sampai Mei 2017. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) yang yang terdiri dari empat perlakuan dan diulang tiga kali. Perlakuan yang diuji dalam percobaan ini adalah: kontrol (Tanpa ZPT), IAA 750 ppm, Growtone 500 ppm, dan air kelapa 10%. Hasil penelitian menunjukkan bahwa pemberian zat pengatur tumbuh berpengaruh terhadap jumlah tunas dan jumlah akar. Jumlah tunas terbanyak terdapat pada perlakuan Growtone sebesar 7.50 tunas. Jumlah akar terbanyak terdapat pada perlakuan IAA sebesar 91.00 buah. Rekomendasi budidaya tanaman miana dengan cara stek dapat menggunakan IAA 750 ppm maupun Growtone 500 ppm.Kata Kunci : miana, stek, zat pengatur tumbuhAbstract : Miana plant is currently used as an ornamental plant. The multiplication of miana crops can be done in a generative and vegetative way. Cuttings is a vegetative way of reproduction of miana plant which is relatively easy to do. Breeding in this way is one of the quick ways in meeting the needs of large-scale plant materials. This research aims to determine the effect of giving Plant Growth Regulator to the shoots cuttings of Miana (Coleus atropurpureus (L.) Benth). Research conducted in the Agroecological laboratory, Faculty of Agriculture, University of Sultan Ageng Tirtyasa. The research will be held in the month of March to May 2017. The study conducted by randomized block design (RBD) which consists of four treatments and is repeated three times. The treatment tested in this experiment was: control (without plant growth regulator), IAA 750 ppm, Growtone 500 ppm, and 10% coconut water. The results showed that the treatment of plant growth regulator affected in the number of shoots and the number of roots. The most number of shoots is in the Growtone treatment of 7.50 shoots. The highest number of roots is in the IAA treatment of 91.00 pieces. Recommendations for cultivation of miana crops with cuttings can use IAA 750 ppm maupun Growtone 500 ppm.Keyword : Miana, cuttings, growing regulatory substances

Abstract

Catfish is one of the important fish commodities in Indonesia. There is some problem that becomes trouble in catfish culture, and the most trouble which cause losses in catfish culture is a disease, especially motile aeromonads septicemia (MAS). The purpose of the study was to analyze the effectiveness of giving dry rabal probiotics for the prevention of motile Aeromonas septicemia (MAS) in catfish (Clarias sp.). This experiment consisted of four treatments, namely catfish farming with the addition of dry rabal probiotics with concentrations of 0%, 5%, 10% and 15%. Catfish (6.03±0.38 g) were reared in a rearing tank with a volume (41x50x57 cm) with a density of 15 fish/aquarium for 50 days. Probiotic bacteria were given daily through feed, while the pathogenic bacteria A. hydrophila was infected on day 51. The results showed that the treatment of giving dry rabal probiotics through feed was effective in improving the immune, and increasing the survival of African catfish. The 10% (C) rabal probiotic treatment gave the best results with the highest survival rate of 75.56 ± 3.85%.

Abstract

The purpose of this research is to evaluate the effect of different concentration of Spirulina platensis supplementation on artificial feed for zebrafish (Danio rerio) to increase growth performance and immunity from environmental pressure. The experimental research was carried out from October until November 2020. The purpose of this research is to evaluate the effect of S. platensis different concentration supplementation on artificial feed for zebrafish (Danio rerio) to increase growth performance and immunity from environmental pressure. The experimental research was carried out from October 2020 until November 2020 at Aquaculture Laboratory, Universitas Sultan Ageng Tirtayasa, Serang, Banten. This research used a complete randomized design (CRD) consisted of 4 treatments and 3 replications. Control was commercial pellet which no S. platensis enriched (A), pellet enriched with 3% of S.platensis (B), pellet enriched with 6% of  S. platensis(C), and last treatment were pellet enriched with 9% of  S.platensis (D). The results showed that treatment C was the best dosage of S. platensis for zebrafish rearing for 40 days both growth and immunity performance. Absolute length, Specific growth rate of length, Absolute weight, Specific growth rate of weight were significantly different, but survival rate were not significantly different which were 0.646±0.112g, 0.714±0.10g, 0.102±0.020%, 1.422±0.215%, 100% respectively. Immunity performance was shown by the stress test at low pH. It was also significantly different when exposed to pH at 5 ppt among the treatment. Treatment C was the highest survival rate which was 63.33±5.77% after stress test at low pH.

Abstract

Oil palm is one of the important plantation crops in the plantation sector. Increased oil palm plantation area causes the need for the availability of oil palm seedlings in large quantities. Good quality oil palm seedlings were obtained through intensive maintenance especially fertilization. Fertilizers needed for the growth of oil palm seedlings include calcium and magnesium fertilizers. The objective of this experiment was to determine the optimum rates of calcium and magnesium fertilizer for oil palm seedling (Elaeis guineensis Jacq.). This experiment was conducted at Cikabayan Experimental Station, IPB Darmaga, Bogor, from December 2011 to November 2012. The experimental design used was factorial randomized block design with three replications. The first factor was Ca fertilizer rates i.e., 0, 5, 10,  and  20 g CaCO3 plant-1. The second factor was Mg fertilizer rates, i.e., 0, 24, 48,  and 96 g MgSO4  plant-1. The results showed that calcium affected stomatal density, whereas magnesium fertilizer affected morphological and physiological variables (stomatal density and chlorophyll content) of oil palm seedling. Based on the plant height and stem diameter, the recommended rate of magnesium fertilizer for 8 months oil palm seedlings in the main nursery was 58 g plant-1. This total rate should be applied at different amount every month from 1-8 month, at 2.0, 2.0, 8.0, 9.3, 8.8, 9.3, 9.4 and 9.3 g MgSO4 plants-1, respectively. The optimum rate of calcium fertilizer was not able to be determined in this research. Keywords: chlorophyll, leaf, morphology, physiology
