Abstract

ABSTRAK   Hasil observasi pembelajaran di SMP Negeri 5 Surakarta khusus pada kelas VIII-F menunjukkan belum optimal dalam proses pembelajaran dan pemanfaatan potensi yang ada. Pembelajaran pada umumnya masih didominasi oleh guru.  Guru adalah satu-satunya sumber ilmu sehingga siswa cenderung pasif dan hanya mendengarkan apa yang disampaikan guru, akibatnya siswa tidak mengembangkan kemampuannya untuk menggali segala fenomena alam di bidang biologi. Kegiatan percobaan umumnya jarang dilakukan, apalagi keterlibatan dalam merancang percobaan. Percobaan umumnya sudah tersedia petunjuk pelaksanaan percobaan, sehingga siswa hanya membuktikan yang sudah tersedia pada petunjuk pelaksanaan percobaan. Akibatnya keterampilan siswa dalam merancang eksperimen masih kurang. Penelitian ini bertujuan untuk meningkatkan keterampilan merancang eksperimen siswa kelas VIII F SMP Negeri 5 Surakarta tahun pelajaran 2011/ 2012 melalui penerapan strategi Guided Inquiry. Penelitian ini merupakan penelitian tindakan kelas (Classroom Action Research) yang dilaksanakan dalam 4 siklus. Setiap siklus terdiri dari 4 tahap yaitu perencanaan, tindakan, observasi, dan refleksi. Subyek penelitian adalah siswa kelas VIIIF SMP Negeri 5 Surakarta  tahun pelajaran 2011/2012. Data penelitian diperoleh melalui penyebaran angket pembelajaran dan observasi. Teknik analisis data adalah dengan teknik analisis deskriptif baik secara kualitatif maupun kuantitatif. Validasi data dengan menggunakan metode belah dua (split half method). Hasil penelitian membuktikan bahwa dengan pelaksanaan tindakan kelas melalui penerapan strategi Guided Inquiry dapat meningkatkan keterampilan merancang dan melaksanakan eksperimen dalam pembelajaran Biologi. Hal ini didasarkan pada hasil observasi. Prosentase capaian indikator keterampilan merancang eksperimen berdasarkan hasil observasi siklus I adalah 47,29 (meningkat 32,82%), siklus II 56,53 (meningkat 9,24%), siklus III 71,21 (meningkat 14,68%), dan siklus IV 75,03 (meningkat 3,82%). Berdasarkan hasil tersebut dapat disimpulkan bahwa penerapan strategi Guided Inquiry dapat meningkatkan keterampilan merancang eksperimen siswa kelas VIII F SMP Negeri 5 Surakarta tahun pelajaran 2011/2012.   Kata kunci:  Keterampilan merancang eksperimen, Strategi Guided Inquiry.

Abstract

Water is important natural resources for people and spring is one of clean natural water resources in the village. Indonesia has high rain fall, but water availability varies spacially and temporally. The change of land cover or ecosystem in spring catchment area or surroundings decreases water catchment capacity. Therefore it is necessary to conduct a study of floor vegetation contribution on rain-water infiltration. This study aims to determine the structures and the roles of floor vegetation in regards of water infiltration at various degrees of slope. This study was carried out in two times, end of the dry season from June to October 2013 and end of wet season from March to June 2014. Floor vegetation data were obtained from 6 plots (1x1m2) in each growth forms and slopes. Water infiltration were analyzed using rain simulation method in 0.5x0.5m2 plot size. Results showed that there were 18 species of 5 families and 29 species of 10 families found during the dry and wet season respectively. Rainy season triggered grass and herbaceous (Poaceae and Asteraceae) plant density from 5 to 9 times, and also shrubs density from 3 to 6 times. Based on important value analysis at slope classes, Panicum repens (34.7%), Ischaemum sp. (34.2%), Elephantopus scaber (33.5%), and Desmodium triflorum (11.9%) are grasses and herbaceous dominated all slopes during both seasons. Boerhavia difussa, Chromolaena odorata, Flemingia macrophylla, and Mimosa pudica are shrubs dominated in all slopes, especially at the steep slopes for the last 3 shrubs.  The diversity index of the floor vegetation can be categorized low. Based on the rain simulation with average rate of 67.6 mLs-1, P. repens and M. pudica, can respectively withstand water runoff for 27s and 18s and had infiltration capacity of 83.2 % and 75.9 % in the steep slope, and E. Scaber can withstand water runoff for 15s and had infiltration capacity 71.6% in the gentle slope.

Abstract

Watershed is the land area that could potentially be a source of water. The main components of watershed ecosystem composed of humans, animals, vegetation, soil, climate, and water. Watershed ecosystem components that are interconnected is going to maintain the quality of the watershed. A common problem in a watershed is the sedimentation due to large amounts of waste, landslides, and erosion. Water and soil conservation efforts in the watershed can be cultivated by maintaining the balance of watershed ecosystem components one of which is the condition of the vegetation diversity. This study intends to analyze the potential of vegetation in water and soil conservation in the watershed. In-depth study based on the results of the analysis of vegetation and 3 sub-watershed namely Keduang, Dengkeng, and Samin which is a sub-watershed in the Bengawan Solo watershed. Analysis of the condition of the vegetation around the sub-watershed Keduang, Dengkeng, and Samin shows that vegetation has an important role in maintaining the quality of the watershed. Vegetation affects the ability of soil to retain water, thus increasing soil water reserves, prevent erosion and landslides in the surrounding watershed. Vegetation potentially in favor of water and soil conservation in the watershed are shrub vegetation, grass, and other plant floor coverings.
