Modeling Folding Zone in Kedungsari Compassionate Area Kulon Progo Yogyakarta with Gravity Method
No full textThis study aims to determine the condition of subsurface by doing interpretation quantitatively. Quantitative interpretation is done by modeling to determine the shape and boundary of the anomaly. The gravity data reduction is done up to Complete Bouguer Anomaly (CBA) value is obtained. The complete Bouguer anomaly is brought to horizontal plane reduction and separation of local and regional anomalies using the upward continuation method. 2.5 modelling has been made from local anomaly data to illustrate the subsurface condition of the research area more clearly. The result shows R1 density value of 2.55 g / m3 which is a limestone and R2 2,8902 g/m3 which is andesitic rock. The position of the anticline axis is at coordinates 49 S 9128700 N 409844.9 E, while the syncline axis is at coordinates 9129037 N 408694,1 E

Manufacture and Characterization of Sensor for Optimizing the Manufacture of Resistance Sensor for Pure Orange Drink and Unpure Orange Drink
No full textThis research was purposed to design and analyze a resistance sensor. This research was done by three steps which are designing, manufacturing and characterizing of resistance sensor. Sensor design was done by using Fritzing software. The tools we used in manufacturing sensor were PCB, resistor, and copper wire. The tools we used in sensor characterizing were power supply, CRO and samples of pure orange drink and unpure orange drink. Sensor characterizing was done by varying samples of 50 ml and 100 ml. Data acquisitiom for each samples were repeated five times. Data generated from the sensor in the form of voltage. The data result of measurement were calculated by its average and its uncertainty. For pure orange drink 50 mL (2.274 ± 1.137); 100 mL (1.688 ± 0.844) and for unpure orange drink 50 mL (2.582 ± 1.291); 100 mL (1.852 ± 0.926). Therefore in the future we can make quality control system of orange drink by optimizing the manufacture of resistance sensors with high-grade characteristics

No full textEthnobotany is a study of the interaction between local communities and their natural environment, especially regarding the use of plants as food and medicinal ingredients. Food plants are a daily basic need whose existence is a necessity for the people on the slopes of Merapi Merbabu. How to use plants is transferred from generation to generation to form a culture. The research was carried out in March-May 2020 with the aim of digging public knowledge of plants used as food, including staple food, vegetables and medicines by studying the species diversity, including the benefits of organs, habit, how to use, process and how to obtain these species. The data were collected by using a combination of qualitative and quantitative methods with in-depth interviews through 40 respondents who were selected by purposive sampling. The results showed that the communities on the slopes of Merapi and Merbabu still used 74 plant species from 37 families as food plants. The favorite family is Fabaceae, followed by Zingiberaceae and Solanaceae. The most widely used hobbits’ were herbs (36.49%), followed by bush (28.38%), shrubs (18.92%) and trees (16.22%). Plant organs that are widely used are leaves (29.73%), fruit (17.57%), tubers (10.81%), seeds (9.46%), roots, rhizomes and flowers (6.76%), shoots (5.40%), stems (2.70%) and water, skin and heart (1.35%). The most common ways to use it are vegetables (29.73%), boiled (16.22%) and drunk (12.16%). How to obtain it through own cultivation (72.97%), and buying at the market (21.62). The highest use values were Adas (Foeniculum vulgare Mill.) (0.25), Lombok (Capsicum annum L.) (0.20), Kunir (Curcuma dosmetica loir) and Kangkung (Ipomoea aquatica Forsk.) (0.17). The highest importance values were Padi (Oryza sativa L.) (5.23%), and Adas (Foeniculum vulgare Mill.) (4.57%)
Morphology of Javan Broadhead Planarian (Bipalium Javanum)
No full textndonesia is one of the countries at the center richest biodiversity in the world, so that Indonesia is referred to as megabiodiversity country. One of the typical fauna in Indonesia is the broadhead planarian Javan (Bipalium javanum). Javan Broadhead Planarian is a parasitic worm that lives in humid areas and is protected from sunlight. Little research has been done on the Javan Broadhead Planarian, especially in terms of morphology. This research was conducted to determine the morphology and characteristics of the planarian broadhead javan. The research was conducted in two stages. The first stage is taking samples of worms at Kedung Pedut Kulon Progo Waterfall. The second stage is taking morphological image data. Data collection of habitat, behavior, dorsal and ventral body parts was carried out using a macro-lens camera, and headplate and creeping sole image data were taken using a stereo microscope. The data taken is in the form of image data taken using a camera with a macro lens and a stereo microscope. Based on the research conducted, the results obtained from the image data of the habitat, behavior, headplate, dorsal and ventral body parts, and creeping sole
