Abstract

In evaluating the effectiveness of the 5Es model with analogy to providing access of deep understanding and attitudes to learn science, a case study research was brought involving 27 undergraduates who took The Human Anatomy and Physiology course. The data gathered were then analyzed using qualitative descriptive technique. The results informed that most students were successful to have deep understanding towards abstract concepts showing by grade of at least C or acceptable level and good attitudes  to  learn  science  within  which  all  students  possessed  the  same  perception  corresponding  to  interest  and  enjoyment regardless any different level of achievement. Overall, it could be concluded that the 5Es model with analogy was quietly effective to make deep understanding and attitudes to learn science appear in students? learning.Dalam mengevaluasi keefektifan model 5Es dengan analogi terhadap pemahaman mendalam dan sikap belajar sains, sebuah studi kasus dilakukan dengan melibatkan 27 mahasiswa yang memprogram Mata Kuliah Anatomi dan Fisiologi Manusia. Data yang diperoleh kemudian dianalisis dengan metode deskriptif kualitatif. Hasil penelitian tersebut menginformasikan bahwa umumnya siswa berhasil untuk memahami konsep yang abstrak secara mendalam yang ditunjukkan dengan nilai minimal C dan memiliki sikap belajar sains yang baik terkait dengan kesenangan dan minat belajar tanpa menghiraukan pencapaian hasil belajar mereka. Oleh karena itu, dapat simpulkan bahwa model pengajaran 5E dan analogi terbukti efektif untuk memunculkan pemahaman konsep secara mendalam dan sikap belajar sains.

Abstract

Dioscorea spp. were cultivated as alternative food in the garden and yard on dry season, and it’s planted by peoples in the villages. The objectives of the research are to identify the species, the tuber use, and the local wisdom to support the conservation of Dioscorea around Wonosadi forest. Samples and data collection was conducted in 15 villages around Wonosadi forest. Interview survey was done on peoples who are cultivate yam species (Dioscorea spp.) in their garden. Research were emphasized to tuber characteristic, traditional uses, and local wisdom to supporting yam conservation. Data was analyzed descriptively to illustrate the kind of local usage and local wisdom of connect with Dioscorea spp. The results showed that there were found species of gembili (D. esculenta (Lour.) Burk.), uwi (D. alata L.), and gadung (D. hispida dennst.) as cultivated plants, and tomboreso (D. pentaphylla L.), gembolo (D. bulbifera L.), and jebubuk (D. numularia Lamk.) as wild species in the forest. Tuber is raw material for many kind of food based on carbohydrate content. Gadung were used as fickle food with high diversification and insecticide for rice and corn. Peoples more consume gembili and uwi than gembolo and others species as rice substitute at dry season. The local wisdom were indicated that peoples still consume gembili and uwi as rice substitute, while tuber also used as sesaji in traditional concept jajan pasar or tukon pasar, and tuber of uwi was used as diet for diabetes complaint, and row material of uwi ungu tuber was used effectively for diarrhea complaint in the villages.

Abstract

Petrozon Rossy-22 is one of hydrocarbon refrigerants which environmentally safe, since there is no effect on either ozone depletion or global warming. In the refrigeration cycle, imperfect vacuuming process or other factors that permit circulation of air taken place in the system predicted influencing heat transfer rate in condenser. Therefore, research on the influence of air fraction against condensation heat transfer coefficient of Petrozon Rossy-22 inside vertical pipe to be done. A modified refrigeration system of vapor compression was applied in this research, where the condensation was done in the 2 meters straight vertical condenser (double pipe heat exchanger, that further called as test section). The diameter of internal and external pipe were ¾” and 1 ¼” respectively. Electric heater was installed on upstream of the test section. Mixture of air- refrigerant was flowed downward inside internal pipe, while cooling water was flowed upward through annulus. The varied parameters were: air fraction, air-refrigerant and cooling water flow rate. The result of the research indicated that condensation heat transfer coefficient significantly decreased when air fraction increased. The proposed empiric equation is :       Nu = 0.0138. (1-w)8.8198. Re0.7941. Pr4.7315with determination coefficient of 0.6927 and average absolute deviation of 17.65 %. The equation was for Re= 6.922-12.953, Pr= 2,008-2,696, and w= (0,25-1)%.

Abstract

The objective of the current investigation is to find out temperature distribution regimes in a horizontal pipe when condensation process is happened.  The research was conducted at Pusat Studi Ilmu Teknik Universitas Gadjah Mada. The experiment apparatus consists of an inner annulus pipe made from copper (din = 17.2 mm, do = 19 mm) with the length of 1.8 m. The outer annulus pipe is a galvanized iron pipe (din = 108.3 mm, do = 114.3 mm) with the length of 1.6 m. Thermocouples type K 36 TT OMEGA with chromel (+) and alumel (-) materials were used as temperature sensors, to detect the spread of temperature in radial or axial direction along the pipe. The measurement ranged from -50 to 260 oC, with an accuracy of 0.01 °C. A data logger of RX 40 serial (OMRON, 20 Channels) was used to read and record temperature data with the sampling rate of 5 Hz. In the experiment, the water (H2O)was heated using a boiler to generate steam which was then flowed and condensed inside the annulus pipe to form a steam-condensate two-phase flow in horizontal pipe. On the other hand, the water was used as a coolant in the outer of annulus pipe. The results indicated that the temperature distribution regimes are influenced by axial posisition.The farther distances from the inlet the lower the temperatures being recorded which indicate the increase of film condensate thickness. Such phenomena can affect slugging in the location.

Abstract

An experiment of two-phase flow patterns of steam-condensate based on differential pressure measurement in horizontal tube was conducted by varying the flow rate of the steam. The experiment utilised annulus pipe with inner section test pipe was made from copper and outer section was made from Galvanized Iron Pipe (GIP) wrapped with a 10-mm-thick insulation. The pipe was 1.6 meter length, and 4 inch outer diameter and 17 mm inner diameter. The two-phase flow regime was investigated based on pressure gradien between its inlet and outlet. In order to support the result, visualition was conducted using a ¾ inch diameter and 1.3 m length of transparent pipe connected with the test pipe section. Five variations of steam flow rate ranging from 0.00211361 m3/s to 0.007078511 m3/s were selected. The results show that for lowest steam flow rate, stratified flow pattern was identified while for the ot her variations, stratified, wavy, plug and slug flow pattern were observed. Wavy flow pattern occured on transition of stratified to slug or plug. Annular flow pattern was not observed in this experiment. Generally speaking, an increase in steam flow rate resulted in a more significant pressure gradient signals.

Abstract

Sampah merupakan problem yang belum terpecahkan di kota-kota besar termasuk kota Semarang. Penanggulangan untuk mencegah timbunan sampah dan melakukan pengolahan sampah secara tepat perlu dilakukan. Salah satu cara untuk menangani sampah khususnya sampah organik adalah menerapkan teknologi, dengan mengolah sampah menjadi kompos. Dengan bantuan mesin pengolah sampah, pembuatan sampah organik menjadi kompos dapat dilakukan dalam jumlah yang besar yang tidak saja bermanfaat bagi tanaman tetapi juga dapat dijual untuk menambah ekonomi masyarakat. Metode dalam kegiatan Ipteks bagi Masyarakat ini adalah penerapan alat pencacah sampah untuk membantu dalam mencacah sampah organik di pasar Pedurungan dalam kaitannya dengan pengelolaan sampah organik pasar menjadi kompos. Pengumpulan data dilakukan dengan cara observasi dan wawancara. Analisis data dilakukan secara deskriptif. Hasil kegiatan adalah terlaksananya kegiatan pendidikan dan pelatihan kepada pengepul sampah untuk memilah sampah organik dan non organik, juga tentang cara membuat kompos, serta manajemen usaha. Alat pencacah sampah digunakan untuk mencacah sampah dalam skala besar. Hasil lainnya adalah telah diproduksinya kompos dan sudah di packing dalam kemasan yang menarik serta telah dipasarkan di sekitar wilayah pasar termasuk di perumahan sekitar wilayah Pedurungan. Terbentuk pula tim manajemen usaha yang terdiri dari unsur UPTD Pasar Pedurungan Kota Semarang dan pengepul sampah.
