Tree architectural model represents one of the important concepts to quip characteristic takson in plant morphology and plant taxonomic. Every tree grows at the watershed has a typical architectural model and different ability in rainfall transformation such as stemflow, throughfall, and interception. This research explores tree architectural models at upstream Cianjur watersheds in Mt. Gede Pangrango National Park. Sampling conducted by using plot method to chose 15 trees at sub-montana zone to measure IVI and elevation bevel. Results of the research indicate that there are 12 tree architectural models at upstream Cianjur watersheds. At sub-montana and montana zone models the architectural models are ATTIMS (1 sp), FAGERLIND (1 sp), KWAN-KORIBA (1 sp), MASART (1 sp), PETIT (3 sp) PREVOST (2 sp), RAUH (2 sp), ROUX (1 sp), SCARRONE (1 sp), STONE (1 sp,) and THEORETICAL I (1 sp).

Payangka fish (Ophieleotris aporos (Bleeker)) is one of the most common fish species in Lake Tondano, North Sulawesi. Due to the availability of this fish throughout the year, it is one of the types of fish consumed by many people. However, the economic value tends to be below. This study diversified payangka fish into nuggets with clove spice (Syzygium aromaticum) and brown seaweed (Sargassum sp) supplementation. The research conducted aims to obtain a proximate profile and fatty acid content of payangka nugget. The research method used is an experimental laboratory method. The study consisted of preparing payangka fish, making payangka nuggets supplemented with clove and seaweed extracts, proximate analysis by gravimetric method and analysis of fatty acid content by gas chromatography method. The results showed that the supplemented payangka nugget had 67% water content, 0.80% ash content, 0.05% total fat, and 10.50% crude fiber. Omega 3 content is 4.75%, while Omega 6 content is 34.16%. Payangka fish nuggets that were supplemented had a higher nutritional content than those without supplementation. Payangka fish nuggets supplemented with clove extract and brown seaweed contain good dietary content.

Patchouli oil (Pogostemon calbin Benth) has economic benefits which are widely used as raw material for the pharmaceutical, perfume and food industries. Although widely used in various fields, patchouli oil or essential oils are generally young to evaporate, are susceptible to high temperatures and humidity, so we need a way / solution to overcome this, one way is encapsulation. Encapsulation is a technique to protect the core material which was originally liquid from becoming a solid / powder form and can protect the core material from losing its taste and aroma. Coating is a material that can mix with the core material, is not reactive to the core material and can form a layer around the core material. Chitosan is a good coating for essential oil encapsulation. This study aims to determine the particle size and microcapsule characteristics of patchouli oil (P.calbin Benth) using chitosan coating. The microcapsules were made using a freeze dryer with the freeze drying method. The dried samples were analyzed for particle size, morphological shape and content using SEM (Scanning Electron Microscopy). The results showed that the samples with a coating material composition of 1:2 were completely dry freeze drying. The average particle size <3.5 µm with a magnification of 10,000x with round morphology and various shapes. Analysis of the chemical content in the sample showed the similarity of the main compounds in patchouli essential oil, namely α-guaiene, azulene, α/β/ γ-patchoulene, seychellene, and α-himachalene and there was the addition of carbon (C) 76.07% and oxygen. (O) 16.46% originating from coating material

The Girian watershed with a length of 17.5 km is the longest river in Bitung City which flows through a densely populated area as well as various industries such as smoked fish, tofu and tempeh, animal husbandry, agriculture, and industrial fish factories whose waste goes directly to the Girian watershed. The great deal of population activities can have an impact on water quality and the Girian watershed ecosystem. This study aims to analyse the water quality of the Girian watershed caused by domestic waste. This study uses a quantitative descriptive approach and the method used in this study is the Indonesian National Standard (SNI) according to the water quality parameters that have been determined. The results of the analysis of water quality upstream to downstream show that there is a decrease in water quality. Upstream is classified as good when compared to the parameters that have been determined. Densely populated areas begin to experience a decrease in water quality, namely with DO and Oil and Fat that exceeds the predetermined quality standard. As well as estuaries that have concentrations of TSS, NH3-N, Oils and Fats, COD, and BOD that exceed the specified quality standards. The results of the calculation of the pollution index show that station point 1 upstream is classified as good in 4 groups, station point 2 in densely populated areas shows lightly polluted results in group 2, and The Station 3 estuary shows moderate pollution results in group 3

Diversity in animals is a variation of the structure, shape, number, and other properties at a particular time and place. Diversity describes a situation that varies from one person to another, objects that occur cause differences in size, shape, texture, and amount. Arthropods are animals with segmented legs, and segments on the body belong to the animals that live both above and below the ground. This research aims to know the diversity and types of ground surface arthropods in the forest surrounding the Department of Biology, Faculty of Mathematics and Natural Science, Manado State University. This research is located in the forest area of the Department of Biology, Faculty of Mathematics and Natural Science, Universitas Negeri Manado, Tonsaru village, South Tondano District, Minahasa Regency, North Sulawesi.
