Gelidium latifolium is one of red seaweed types potentially can be developed as an industrial raw material. Since Gelidium is currently taken from ocean, the availability of seaweed from aquaculture is necessary to overcome the small number of its availability in nature. In Indonesia, G. latifolium cultivation has not been carried out so that domestication is required. The use of macro and micro nutrients in growth media is essentially needed for the domestication process. Domestication requires fast media and place for growth. The purpose of this study is to determine the growth of biomass and the survival of G. latifolium in different culture media. The study was conducted in a semi-outdoor research laboratory. The method used in this research is laboratory experimental method and Completely Randomized Design (CRD) with the treatment applied using 3 types of culture media (Urea: Za: TSP) by comparison (A) 100: 50: 50% (2 g.L-1), (B) 75: 75: 50% (2 g.L-1) and (C) 75: 50: 75% (2 g.L-1), with 3 replications. The seaweed was kept in 10 L of water in aeration equipped aquarium and filled with 10 g of G. latifolium on each treatment. The best growth rate of G. latifolium biomass is 5.67± 0.58 g and 100±0% are survived in C culture medium with a concentration of 75% Urea: 50% ZA: 75% TSP (2 g.L-1).

Lemna minor is a small water plant that floats on water and has the potential to be fresh feed for fish. Bioslurry is a by-product of the management of biogas from livestock manure which is often used as fertilizer for plants because it contains nutrients in a readily available form. Among the contents contained in bioslurry, manganese and lead are important things related to their use for plants and fish. This study aims to determine the mineral (Mn) and lead (Pb) content in the medium of lemna cultivation which is fertilized with various doses of bioslurry. The study was conducted at the Ciparanje Experimental Pond, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran, Indonesia. This study used an experimental method with Completely Randomized Design (CRD) with four treatments with three replications. The treatment in the form of adding bioslurry to the lemna culture media was 0.00%, 0.25%, 1.00% and 2.50% of the volume of water. The minor density of Lemna used is 800 g/m2. The culture was carried out in 4 cycles for 7 days. The parameters observed were Mn and Pb content in the lemna culture medium shortly after the addition of Bioslurry and after 7 days of lemna cultivation. Based on the results of the study, the use of 2.5% bioslurry concentration can produce the highest Mn content with a range of 2.0-4.6 ppm and 2.92 ppm Pb content after 7 days of lemna cultivation. In addition, the use of 2.5% bioslurry concentration resulted in Mn and Pb values in the culture medium shortly after stirring bioslurry in the lemna culture media. Based on the research results, the treatment of adding 2.5% bioslurry to the lemna culture media is the best dose for produced Mn for fish, as well as the safest Pb for aquaculture activities.

ABSTRACT Brazil is the second largest soybean producer in the world, with a yield of around 96.2 million tons per crop. This high yield leads to a great amount of waste resulting from soybean cultivation, which can reach approximately 41 million tons of waste per year. This material has lignocellulosic properties, which may enable its use as a raw material for particleboard production. Therefore, the objective of this study was to evaluate the use of soybean pods in particleboard production. For particleboard manufacture, wood of the hybrid Eucalyptus urophylla and Eucalyptus grandis was used, added with soybean pods, at proportions of 0%, 25%, 50%, 75% and 100%. For particleboard evaluation, a completely randomized design was used, with five treatments and three replicates, using linear regression and the Scott-Knott test at 5% significance for comparison among the different treatments. The properties apparent density, compaction ratio, water absorption after 2 and 24 hours, thickness swelling after 2 and 24 hours in water immersion, internal bonding, modulus of rupture and modulus of elasticity in bending properties were evaluated. The ratio soybean pod waste and eucalyptus particles in the panels led to an increase in water absorption values and thickness swelling, in addition to a decrease in mechanical properties. The production of panels with approximately 23% soybean pods is feasible.

ABSTRACT Some factors may influence the in vitro culture of native orchids, especially the culture medium, sealing system and light condition. This study aimed to evaluate the addition of banana pulp and peel in the formulation of culture media, sealing system and irradiance, in the in vitro growth of Cattleya nobilior Rchb. f. A completely randomized design was used in a factorial scheme with five culture media [Murashige & Skoog supplemented or not with banana pulp or peel (100 or 200g L-1)], two light conditions [3,000 K LED lamps (43 µmol m-2 s-1 or 86 µmol m-2 s-1)] and two sealing systems (natural and conventional ventilation), with six replicates of one vial each. The plant height, diameter of the largest pseudobulb, length of the largest root and of the largest leaf, fresh weight and number of leaves, roots and shoots were evaluated. The use of both the banana pulp and peel as additives in the culture medium formulation promoted the C. nobilior growth. The natural ventilation system increased the plant height, pseudobulb diameter and leaf length, while the conventional system promoted tillering.
