Abstract

Rabbits are livestock that has the potential to provide meat in a relatively short time, so people's consumption of animal protein is expected to be fulfilled. Market vegetable waste can also be used as feed, especially for rabbits. When processed into rabbit feed, waste is not only a product, but from the feed consumed by rabbits, it can produce meat of good quality. This study aimed to determine whether feeding vegetable waste can increase rabbit body weight and whether combining pellets and vegetable waste can increase rabbit body weight. This study used a quantitative experimental method using an experimental design that was Completely Randomized Design (CRD) with six treatments and four replications. The survey results showed that feeding vegetable waste was effective as feed for rabbits because it could increase the body weight of rabbits (Oryctolagus Cuniculus L.). The more balanced the market vegetable waste feed in the form of cabbage, carrots, pattern (young corn shoots) and pellets were given, the higher the weight gain of rabbits (Oryctolagus Cuniculus L.). Market vegetable waste is not recommended as a good feed. Still, it can be used as a supplement only because research results show that market vegetable waste does not have a significant effect.

Abstract

Tamba Beach has several ecosystems, namely seagrass beds, sandy and rocky. Ecologically, seagrass beds are home to marine life, including Echinodermata. Echinoderms play an important role as an integral part of the food chain, eating organic waste. The purpose of this study was to analyze the community structure of Echinoderms at Station I (Seagrass Zone), Station II (Sandy Zone) and Station III (Coral Zone). Two methods are used in this study. The first is a qualitative description method by directly observing and quantitatively calculating the diversity index, uniformity index, dominance and abundance index formulas. The echinoderms found consisted of 4 classes, namely Holothuidea, Ophiuroidea, Echinoidea and class Asteroidea. The echinoderms found at the study site used a diversity index classified as stable. The dominance index is low because there are no dominant individuals, and the uniformity index is low. From the results obtained from the abundance in Tamba Beach, the highest value was in the Diadema setosum species with 113 individuals. Diadema setosum has the highest quantity at the three existing stations. This species can adapt to environmental changes.

Abstract

This study aims to inventory orchid species in the West Tomohon area using the accidental sampling method of exploration in a predetermined place. Orchids are a type of flowering plant that comes from the Orchidaceae family. Each type of orchid has its own characteristics. Tomohon City has abundant natural resources, including ornamental plants such as orchids. Data on orchid diversity in West Tomohon Sub-district has never been reported. Orchid inventory is an activity that records the diversity of orchid species in an area. This research is descriptive-qualitative research. The results of this study have yielded 10 species of orchids belonging to nine genera in one family. The orchid species found in the West Tomohon area consist of Arachnis sp., Arundina graminifolia, Cattleya sp., Dendrobium biggibum, Dendrobium moschatum, Epidendrum secundum, Oncidium flexuosum, Phaius tankervilleae, Phalaenopsis amabilis, and Vanda arcuata. The most common orchid found in this area is the moon orchid, Phalaenopsis amabilis.
