Abstract

AbstractCats are domesticated animals whose existence is very close to humans. Maintenance of the wrong cat will cause the risk of zoonotic diseases. to humans caused by ectoparasites. Ectoparasites in cats are fleas, mites, and fleas. Information regarding the prevalence of ectoparsite infestation in cats can be used as a preventive measure. The purpose of this final report is to explain the prevalence of ectoparasites in cats at the Winadivet Animal Clinic in Malang. Prevalence sample examination was carried out on 156 cats divided into 7 breeds, namely Domestic, Persian, Bengal, British Short Hair, Peaknose, Anggora, Himalayan who came to the clinic during April 2021. Examination was carried out macroscopically and microscopically, microscopic method using native method. The results of the examination found 45 cats that were positively infected with ectoparasites, namely the Ctenocephalides felis flea, Felicola subrostatus fleas, Otodectes cynotis mites, and Sarcoptes scabei. The prevalence of infestation obtained was 28.8%. The highest prevalence of ectoparasites in purebred cats is in domestic cats with a prevalence value of Ctenocephalides felis 12.7%, Felicola Subrostatus 5.1%, Otodectes cynotis 3.2%, Sarcoptes scabei 0.6%. Factors that influence the high prevalence are environment, temperature, humidity, maintenance, and direct contact from infected animals.

Abstract

Coffee is one of the drinks that are often consumed by the public Indonesia. Indonesian Coffee and Cacao Research Institute (ICCRI) is a national coffee and cocoa research and development institution has 2 superior Arabica coffee seeds, namely Andungsari 2K Arabica Coffee and Komasti (Andungsari 3 Composite). In general, the sequence of dry processing of coffee cherries includes fruit picking, fruit sorting, fruit drying, pulping and hulling. Next is the roasting process before it becomes coffee grounds. The roasting process converts unsavory raw coffee beans into a drink with a delicious aroma and taste. The perfection of coffee roasting is influenced by 2 factors, namely heat and time, equipment and tools roasting and quality of coffee beans. From the results of treatments 2, 4, 6, 8, 10, 12, 14, 16 and 18 minutes, coffee with city roast criteria was produced in the 7th treatment, namely 14 minutes, with the first crack at 11.30 minutes at 154 °C, the color of the beans dark chocolate, has the most popular taste. For treatment 8 (14 minutes) and 9 (18 minutes) the color is more black, oily and smokey, the taste is more espresso. The roasting equipment used is in the dark roast category at a temperature of 170-195 °C.

Abstract

Fungi are one of Indonesia's potential natural resources which contain various benefits for human life. The existence of macroscopic fungi is not yet well known so that little information about the types and their benefits is known to local people. In fact, information about species of fungi is very important because fungi have economic value and are producers for the food and pharmaceutical sectors. Populations of macroscopic fungi can disappear due to climate change and environmental factors, therefore, it is necessary to collect data on the species of macroscopic fungi. One way to detect the species of fungus is to classify it based on the morphological characteristics of the fungus with K-Nearest Neighbor. The aim of this research is to explore and identify the morphological characteristics of fungi using K-Nearest Neighbor as a classifier found in the Bukit Selebu traditional forest area, Merangin Regency. It is hoped that the results of this research can be the first step in efforts to utilize fungi through further research. This research was carried out in the Bukit Selebu traditional forest area, Merangin Regency and identification continued at the Biology Laboratory of Merangin University. Then the data on the species of fungi found were analyzed using k-Nearest Neighbors (kNN). The results of this research are that there are 27 species of fungi found in the Bukit Selebu traditional forest area, Merangin Regency, consisting of 3 species of Ascomycota divisions and 24 species of Basidiomycota divisions. The K-Nearest Neighbor method is very good in classifying fungi through the extraction of morphological characteristics with the highest accuracy reaching 93%.

Abstract

Dendrobium mussauense has attractive flowers and potential as a parent of a hybrid orchid. The color of this species is cream with violaceous purple venations on the labellum. D. mussauense is an orchid species listed as vulnerable in IUCN. This species is not located in protected areas nor known to be conserved ex-situ. Clonal propagation is an important biotechnological tool for the conservation of orchids. Thin cell layer (TCL) is a micropropagation method using thin-sized explants that facilitate the diffusion of nutrients to tissues. This study examined induction shoot through two explant cutting techniques, namely TCL and non-TCL explant, at various concentrations of BAP. The non-TCL explant was more effective than the TCL explant in inducing the shoot of D. mussauense. The half-strength Murashige and Skoog (MS) medium supplemented with 0.9 mg.L-1 BAP was a suitable concentration to induce the shoot of D. mussauense through non-TCL explant. The average shoot length was 1,8 cm, and the average number of shoots was 5/explant.

Abstract

One of the most biodiverse nations in the world, Indonesia is home to a wide variety of butterflies as well as other animals and plants. Butterflies play a significant role in the ecosystem, both in the pollination process and in the process of detecting environmental changes in the ecosystem. One alternate strategy for preserving biodiversity and natural resources while boosting a nation's economy is ecotourism. This study aims to investigate the perceptions and attitudes of local communities in West Sumatera regarding with butterflies and ecotourism. The study was conducted from February to March, 2023 by using two-page questionnaire developed to collect social information regarding with ecotourism and butterflies through in-depth interview with respondents who was currently living in West Sumatra. A total of 30 respondents (15 Male, 15 female) from various background were questioned. According to the survey’s findings, the majority of the population (93%) was passionate about protecting biodiversity and has extensive understanding of ecotourism and butterflies. Additionally, the majority of respondents (93%) mentioned that they would love to join Butterfly Watching Program. The respondents indicated that West Sumatera has a lot of ecotourism destinations. To draw visitors, a more sophisticated ecotourism program centered on beautiful wildlife and flora should be established.

Abstract

The plankton community structure is a collection of zooplankton and phytoplankton populations that interact with each other in a waters. This study aims to analyze the structure of the plankton community and the influence of environmental conditions (physico-chemical) on the structure of the plankton community in the ponds. The research sample was taken using a purposive sampling method, which represents three types of catfish ponds, namely, earthen ponds, tarpaulins, and biofloc. The results showed that in the three types of ponds studied, there were two species of zooplankton and 45 species of phytoplankton. Phytoplankton in soil ponds was dominated by Stigeoclonium subsecundum. Meanwhile, the zooplankton was dominated by Nebela collaris. Diversity (H') of zooplankton is in the low category with polluted water quality in the three ponds, while phytoplankton is in the high-low category. The equitability index (E) of zooplankton is in the stable category, while phytoplankton is in the depressed-stable category. The dominance index (D) of zooplankton belongs to the medium-low category, while phytoplankton belongs to the low category. As for the physico-chemical parameters of the waters, the three types of ponds have different effects from each parameter tested on the structure of the plankton community.

Abstract

A micro-mushroom namely Sphaerobolus stellatus (BO 24422) and macro-mushroom namely Trichaleurina javanica (BO 24420) were found in Landscape Arboretum of IPB University. The latest identification used morphological characteristic and molecular study of Large Subunit DNA marker respectively. According to their identification, the database of fungal identification is commonly from Internal Transcribed Spacer (ITS) marker for molecular study. But both specimens, S. stellatus BO 24422 and T. javanica BO 24420, have not the ITS sequences yet. This research aim to study the molecular data of two specimens using ITS sequences. The method of this research used the molecular identification using internal transcribed spacer (ITS) primer: ITS 4 as a forward and ITS 5 as a reverse. Two phylogenetic trees were generated by Randomized Axelarated Maximum Likelihood (RAxML) Black box. Bootstrap (BS) values ≥ 90% were displayed on the phylogenetic treebranches. The result showed that the bootstrap value for S. stellatus BO 24422  showed the good value as 96% classified as S. stellatus. Then, T. javanica BO 24420  had a better BS value with 93% classified as T. javanica. The ITS is a general marker and very useful for molecular identification.
