Abstract

The role of insects (arthropods) in human life can affect the yield and quality of agricultural products. Insect pests are insects that regularly or occasionally cause damage that can reduce the yield or quality of agricultural products. The purpose of this study was to determine the  preference of arthropods on wild plants, to compare the percentage of interest and time orientation of arthropods on wild plants. This research is a qualitative descriptive that tries to reveal andexplain about the preferences or interests arthro in Poda against wild plants (weeds) Cambodgien Wonosari Tea Garden Area, Singosari Malang. The difference in the percentage interest in insects against wild plants affected by volatile compounds secreted by wild plants. Overall plant contain  volatile compounds produced by the leaves, flowers or fruit of the wild plants cause differences  insect attraction. Insects itself able to select and respond to volatile compounds from plants that are in nature can be visited.Keywords : insects, arthropods, wild plants.

Abstract

Sungai merupakan suatu ekosistem air tawar ditandai dengan aliran yang diakibatkan karena adanya arus. Arus adalah aliran air yang terjadi karena adanya perubahan vertikal per satuan panjang. Sungai juga ditandai dengan adanya anak sungai yang menampung dan menyimpan serta mengalirkan air hujan ke laut melalui sungai utama. Tujuan dalam penelitian ini adalah Untuk mengetahui kualitas air Sungai Brantas di Kota Malang ditinjau secara kimia (BOD dan COD) dan fisika (Suhu dan pH), Untuk mengetahui kualitas air Sungai Brantas di Kota Malang dengan menggunakan Tubifex sp sebagai bioindikator, Untuk mengetahui kesesuaian antara indikator pencemaran kimia-fisika yang digunakan dengan Tubifex sp sebagai bioindikator. Penelitian ini termasuk jenis penelitian deskriptif eksploratif dengan pendekatan kuantitatif. Pengambilan Tubifex sp dilakuakn pada stasiun pengamatan yang terdapat pada beberapa lokasi. Pengamatan dilakukan terhadap Tubifex sp dan beberapa faktor kimia-fisika yang mempengaruhinya di Sungai Brantas. Organisme yang hidup di dalamnya dapat berupa benthos, nekton maupun plankton. Sungai alami dibentuk oleh aliran air tanah, sungai terus mengalami perubahan karena masukan bahan-bahan dari daerah sekitarnya, akibat erosi dan dekomposisi tanah. Perubahan fisika kimia air akan diikuti oleh perubahan komposisi fauna.Kata kunci : Tubifek, bioindikator, faktor fisika-kimia

Abstract

The aim of research to determine the type of stomata in the leaves of plants Xerophyte euphorbia(Euphorbia splendens), mesofit plant Hibiscus (Hibiscus rosasinensis), as well as hidrofit kale plant(Ipomoea aquatica). The research methods is descriptive qualitative to describe and interpret the type of stomata on the leaves. Type of stomata on the leaves of Xerophyte is anomositik. Mesofit planthibiscus (Hibiscus rosasinensis) has a parasitic type of stomata. Hidrofit plant (Ipomoea aquatica) isanisositik, that is cells surrounded cover three neighboring cells that are not as great.Keywords: stomata, of plants hidrofit, mesofit, Xerophyte

Abstract

This research was a classroom action research which was conducted intwo cycles, each cycle consists of planning, implementing, observing, and reflecting. The data used was quantitative data on student observation sheet instruments. The Results of the study which were obtained from the first cycle showed about the students’ thinking skills and scientific works. They were categorized as excellent 18.18%, good 22.73%, enough 52.27%, and sufficiently less 6.82%. As for the scientific attitude with a very active category of 11.36%, 43.18% and less active 45.45%. It has not reached indicators of success, so it was necessary to cycle II. Cycle II demonstrated the excellent category 38.63%, 36.36% good, good enough18.18% and less 6.81%. While the scientific attitude in the cycle II was an active attitude 29.54%, active 54.54%, inactive 15.91%. These results show an increase from the cycle I to cycle II. The conclusion of this study were: 1) learning the basic concepts of science with scientific inquiry in students can be conducible applied.2) Learning the basic concepts of science with scientific inquiry can improve thinking ability and scientific work and students’ scientific attitude. 3) Learning the basic concepts of science with scientific inquiry be able to explore and develop student creativity in designing simple experiments which can be applied in primary schools.

Abstract

This sresearch aims to apply the SETS approach (Sceince, Environment, Technology, and Social) to improve scientific literacy through understanding science concepts, basic science process skills and scientific work on science learning for fifth grade students of SDN 02 Mojorejo Madiun City. The method used in this study is Classroom Action Research (CAR) which consists of 2 cycles. each cycle has 4 stages, namely planning, implementing, observing, and reflecting. the subjects in this study are fifth grade students of SDN 02 Mojorejo. The results of the study using the SETS approach (Sceince, Environment, Technology, and Social) in natural science learning showed an increase in scientific literacy, namely the maintenance of the science concept in terms of an increase in the class average value with a cycle value of 76.71 and an increase in 77 in cycle II. 81, there are basic process skills in students in the first cycle 30% and second cycle 60% and the scientific attitude of students in the second cycle that shows high categories, namely very good. Based on the results of the above study it can be concluded that the use of the SETS approach (Sceince, Environment, Technology, and Social) can improve scientific literacy through understanding the science concept, basic process skills and scientific work of students at SDN 02 Mojorejo Madiun in science learning with green plant matter.
