Abstract

Seaweed is a low-level plant, does not have exact roots, stems, and leaves, and the plant part is called the thallus. One species that is often cultivated by the seaweed farmers in Bali is Eucheuma cottonii. The initial weight of the seeds planted can affect the growth of seaweed. The results of the study found that good seaweed seeds used ranged from 50-150 g, but has never been studied in detail on E. cottonii using floating raft method. This study aims to determine the initial weight of seaweed seeds that are good for growth using the floating raft method where the seeds are placed in a bag. This study consisted of 3 treatments, namely treatment A with a seed weight of 50 g, treatment B with a seed weight of 100 g, and treatment C with a seed weight of 150 g. This research was conducted at Pandawa Beach, Bali, from March-April 2021, which data was collected once a week for 7 weeks. The results showed that the growth of seaweed increased every week and different between treatments. The final weight of seaweed in treatment A was 558.83 g, treatment B was 552.167 g, and treatment C was 529.67 g. Seaweed growth in treatment A was higher than treatment B and C. The average Specific Growth Rate (SGR) in treatment A was 4.92%, treatment B was 3.48%, and treatment C was 2.57%. The best results from the seeds used were found in seedlings with an initial weight of 50g, compared to the weight of other seeds (P<0.002).

Abstract

Bali has the potency to grow plantation, particularly cacao plants (Theobroma cacao). The increase of cacao production is supported by the increase of the number of productive cacao plants, but the production rate per hectare per year decreased at some districts. One reason of the decreasing cacao production was due to the attack of Plant Disease Organism. This research aimed to investigate the insect families associated with cacao plantations and the fuctions of the insects on cacao plants, at Bedulu Village, District of Blahbatuh, Gianyar Regency. Samples were collected from January to February 2011 and insect identification was conducted for two months at Animal Taxonomy Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Udayana University. Field sample collections were arranged by randomized sampling techniques that the block samples were chosen randomly. Samples were collected with beating technique and trapping with sex pheromone. All insects collected from the field belong to eight groups/types. The highest percentage of insect type collected fuctioned as vector (56.1%) and the lowest was acted as parasites (0.1%). The highest number of two groups insects captured were groups of pests and predators. The insect that function as biological control was the family of Labiduridae, Anthocoridae, Reduviidae, Chrysopidae, Gryllidae and Chalcididae.

Abstract

Research on reproduction patterns of Balinese snake skin fruits (Salak Bali) has been conducted by identifying the availability of pollens on anthers of male and hermaphrodite flowers, the viability of pollens in the pistillum and the present of embryo(s) in the ovulum. Flower samples were collected from Sibetan and Muncan Villages, Karangasem regency. Sample preparations and identifications were conducted in "Stuktur dan Perkembangan Tumbuhan Laboratory" Department of Bilogy, FMIPA Udayana University. The results showed that the pollen has a single apperture, unisulcus, minuta, oblat sferoidal type. The length of polar axis was 15-24 jam (P) and equatorial diameter of 16-24 |im (E). Therefore, the P/E index was 0.99-1.0. The pollen viability before and after anthesis of hermaphrodite flowers was low (71.4% and 50.6% respectively), with very low pollen tube germinations (0.08% of before and 0.48% after anthesis). Similarly, on the anthers of male flowers, the viability of pollens before anthesis was low (75.7%) with pollen germination of 0.18%, and event lower in after anthesis flowers (28.8%) with 0.29% pollen tube germination. Squashed stigma before and after anthesis and 2 days after flowers were opened showed that there was no germination occurred. Therefore, there was no germination in the pistillum, but the embryo developed before flower anthesis, indicates that the reproduction pattern of Salak Bali occurred without fertilizations (agamospermy).
