Abstract

Orchid is the general name for all types of plants in the family Orchidaceae (family of orchids). This family is one of the largest groups among other flowering plants. It is estimated that worldwide there are around 15,000-20,000 species of orchids with 900 genera (clans) that grow endemic to forests scattered in various countries. Of all orchid species in the world, 5,000 of them are in Indonesia. Broadly speaking, the classification of orchids is divided into 5 subfamilies, 16 tribes (tribes), and 28 subtribes. Phalaenopsis is a genus of orchids which is popular for its diversity and beauty of flowers. The government through presidential decree (Kepres) No. 4 of 1993, on January 9, 1993, designated the moon orchid as a charm flower named Latin Phaleonopsis amabilis, this orchid grows attached to a tree trunk or branch and is one type of orchid endemic to Indonesia. The development of orchid cultivation has never been separated from disease and pest problems. With few disease infections and pest attacks, the beauty will change, of course, the selling price will fall. Orchid plants require extra care to grow with beautiful flowers. Orchid disease can be caused by bacteria, fungi or viruses. Diseases and pests that attack orchid plants can cause death if allowed to continue. Besides that, mishandling can also cause the death of orchids. The purpose of this study was to determine the pests and diseases of the Phalaenopsis amabilis plant.This research was conducted on December 2, 2020 and January 13-14, 2021 in Carikan Sukoharjo with 10 samples of Phalaenopsis amabilis plants. The tools needed in this research include writing tools, tables, loops and documentation tools (cellphone cameras). The variables to be observed were diseases and pests that attacked. The methods used were direct observation and interviews, the data obtained were analyzed by qualitative descriptive.Research conducted on 10 samples of Phalaenopsis amablis, found 6 pests and 2 diseases. Pests on the Phalaenopsis amabilis Moon Orchid plant are found that very often attack such as ants, snails, grasshoppers, mealybugs, mites and caterpillars. Whereas in the disease of the Moon Orchid plant (Phalaenopsis amabilis) in the search for Sukoharjo, the fungus Fussarium oxyporum and Rhizoctonia solani attack the leaves, stems, roots of Phalaenopsis amabilis. This disease enters the plant tissue through stomata or wounds in plants. In general, the characteristics of a fungal attack include small spots on the leaves, blisters like being scalded, watery, either cloudy or clear.

Abstract

Ethnozoological study is a study that examines the relationship between humans and animals in traditional studies. People's knowledge in relation to these animals has been passed down from generation to generation to become local wisdom. This ethnozoology includes the matter of raising animals, managing animals for medicine, food and customary and ritual activities, as well as the reciprocal relationship between humans and surrounding animals. The people of Kampung Naga are indigenous people located in Tasikmalaya who still adhere to the local wisdom they have today. Due to the absence of a study on ethnozoological studies in the Kampung Naga community, research was carried out on animal maintenance and control of rice pests which were included in the study of ethnozoological studies. The data collection techniques in this study were interview techniques and documentation with qualitative research methods. The results of the study found that the people of Kampung Naga have local wisdom regarding the control of agricultural pests, the main pests are brown planthopper, walang sangit, rats and birds as well as animal maintenance including chickens, goats, fish, guinea pigs and rabbits. This study aims to describe the study of ethnozoological studies of the people of Kampung Naga, Neglasari Village, Salawu District, Tasikmalaya Regency as a source of learning biology in the form of a booklet.ETNOZOOLOGI: STUDI KEARIFAN LOKAL MASYARAKAT ADAT KAMPUNG NAGA TASIKMALAYA

Abstract

Increased consumption of fruit requires consumers to understand how to choose good and ripe fruit. The level of fruit maturity can be known based on physical characteristics, including the parameters of size, weight, skin color, fragrance of the fruit, and the level of hardness of the fruit flesh. Determining the level of fruit maturity based on physical characteristics has a weakness that is subjective and inconsistent. Making indicators based on natural dyes, namely anthocyanins, to determine the level of sweetness of the fruit. The purpose of this research is to use anthocyanin pigments as an indicator of fruit sweetness level to determine fruit maturity. This research is an experimental laboratory and qualitative descriptive analysis with stages; Sample Extraction, Indicator Making, Indicator Application, Fruit Acidity Testing, Data Analysis. Based on the results of the study, there were quite visible color differences on toothpicks after being inserted into the fruit samples with a sweet taste and the fruit samples with a sour taste. The indicator shows that fruit with a sour taste (pH < 3) changes color from blue to reddish purple. If the taste is not too sour (pH 5), it does not experience a significant color change. In conclusion, the anthocyanins in telang flower can be used as an indicator solution because they have a blue color at neutral pH, a reddish color at pH = 2, the red color fades at pH = 3 and 4, and there is no color change at pH 5.
