Betok fish is very popular with the people because of the delicious and tasty taste of the meat, therefore this type of fish is quite potential for cultivation. (Muslim 2008) in (Anggara et al 2013). Most people who cultivate betok fish (A.testudineus, Bloch) do not understand their character or behavior, so that many farmers experience complaints in maintenance, especially in their growth and survival. As an alternative to the maintenance of Betok fish (A. testudineus, Bloch), the growth rates and viability of the Betok (A. testudineus, Bloch) fry were reared in a container using a shellter. The research design used was an environmental design RAL (completely randomized design) consisting of 4 (four) treatments and 3 (three) replications. The treatments were as follows: Treatment A: Betok fish seeds (A. testudineus, Bloch) without treatment (control), Treatment B: Betok fish seeds (A. testudineus, Bloch) were given a bamboo shellter ,, Treatment C; Betok fish (A. testudineusBloch) was given a coconut shell shellter, Treatment D: Betok fish (A.testudineusBloch) was given a paralon shellter. The results showed that betok (A. tetstudineus, Bloch) seeds were maintained using a shelter (Treatment C and B) resulted in better survival rates (99.35% & 98.07%) than treatments A and D (96.15% & 96.79%).

       The people of Hulu Sungai Utara Regency are very fond of pineapple, this can be seen from the continued increase in market demand for pineapple. Pineapple production in Hulu Sungai Utara Regency from 2010-2013 continues to increase. However, the availability of pineapple is still widely supplied from other regions. This is due to limited land and the availability of superior seeds. Therefore we need a new technique to overcome this problem by multiplying it in vitro. This study aims (i) to determine the response of pineapple plant growth to various concentrations of IBA (Indole Butyric Acid) in vitro and (ii) to obtain the best IBA (Indole Butyric Acid) concentration for pineapple plant growth in vitro. The study was conducted in the Amuntai STIPER tissue culture laboratory from March to June 2014, using a Completely Randomized Design (CRD) with 5 treatment levels, 4 replications.

The need of rice as the staple food of the people of Indonesia has a deficit every year. Upland rice cultivation in dry land such as Ultisols became one of the alternatives to meeting the needs of rice. However, productivity of crop in Ultisols is low because of some problems of acidity and nutrients deficiency. It is necessary input such as ameliorants like biochar cocopeat of oil palm empty bunch compost (OPEBC) and the use of bacterial non-symbiotic nitrogen fixation (NSNF) to fix the problems. The research aims to study the effect of application of ameliorant and suspensions of bacterial isolates of NSNF on growth and N uptake by upland rice in Ultisols medium. The research was conducted at the Green House of the Faculty of Agriculture, University of Riau, Pekanbaru from Mei to September 2017. The research in form factorial experiment was arranged a completely randomized design (CRD). The first factor were ameliorant, consists of six type (biochar, cocopeat, OPEBC, biochar+cocopeat, biochar+OPEBC, each doses 50 g polybag-1 and without ameliorant as a control). The second factor were suspensions of bacterial isolates of NSNF, consists of three levels (10 and 20 ml polybag-1 and without bacterial isolates as a control). The parameters observed were plant height, number of tillers, weight of dry shoot and roots, N uptake by shoot and roots. The results show that the application of ameliorant (biochar, cocopeat, OPEBC, biochar + cocopeat, biochar + OPEBC), each doses of 50 g polybag-1 and suspensions of bacterial isolates of NSNF doses of 0, 10 and 20 ml polybag-1 increased plant height, number of tillers, weight of dry shoot and N uptake by shoot compared to control and the application of without ameliorant with suspension of bacterial isolates of NSNF doses of 0, 10 and 20 ml polybag-1.Key words : biochar, cocopeat, palm oil empty bunch, upland rice, ultisol

The an annual herbaceous tropical plant which is one of the species of the genus Tacca from the Dioscoreaceae family is Tacca chantrieri. T. chantrieri has a unique inflorescence morphology like that of a bat. The people of Southeast China and Thailand have used by T. chantrieri rhizome as traditional medicine because the methanol extract contains secondary metabolites such as diarylheptanoids, pseudofurostan, withanolide, taccalonolide, and saponins. To maintain its sustainability, it is necessary to propagate T. chantrieri by using in vitro culture techniques such as callus culture. The purpose of this study was to determine the response of T. chantrieri leaf callus formation and to determine the optimal concentration with various concentrations of 2,4-D and BAP in vitro. This study used a completely randomized design consisting of control treatments, 1 and 2 mg L-1 2,4-D and concentrations of 0.5; 1.0; 1.5; 2.0 2,4-D combined with 3 mg L-1 BAP. The observations were made for 60 days after planting. The results showed that the concentration of 1.5 mg L-1 2,4-D + 3 mg L-1 BAP affected the percentage of live explants and the percentage of callus formation by 100% respectively, and the time of callus appeared 18.75 days after planting.

Food preservation techniques to improve the oxidative stability of fish-based foods are gaining renewed research interest in natural compounds of vegetable origin as valid alternatives to synthetic preservatives. This study was designed to determine the effect of Onion Top Leaves Extract (OTLE) on the chemical and sensory qualities of smoked Heterotis niloticus using four concentrations (0, 0.25, 0.5 and 0.75% w/w) and three storage periods replicated four times in a Completely Randomized Design (CRD). A total of 48 fresh samples of H. niloticus were treated with the different concentrations of OTLE, sundried for three hours and smoked using a modified portable drum kiln designed in the laboratory. The treated smoked samples were packaged in paper envelopes and stored at room temperature for a period of three weeks. The results indicated that OTLE concentration had significantly affected (P<0.05) moisture content, crude protein, crude fibre, nitrogen and total volatile base – nitrogen (TVB-N). The storage period was significantly affected (P<0.05) by OTLE for all tested chemical parameters except carbohydrates, (P>0.05). The results for sensory qualities indicated that after three weeks of storage, OTLE exerted a significant effect (P<0.05) on all sensory qualities tested in the study except general acceptability. The results for merit analysis showed that the samples treated with OTLE concentration of 0.25% ranked better followed by 0.5% while 0.75% recorded the lowest performance. For better optimisation of shelf life, chemical and sensory qualities of smoked H. niloticus, the product can be preserved in 0.25% w/w OTLE and stored for one week at room temperature in paper envelopes.Res.
