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

Pembelajaran di era revolusi 4.0 menuntut kompetensi pendidik yang dapat menguasai teknologi dan pemanfaatannya dalam proses belajar mengajar. Teknologi dalam proses belajar mengajar dapat membantu memvisualisasikan materi serta mampu meningkatkan motivasi belajar siswa. TPACK (Technological Pedagogical and Content Knowledge) merupakan sebuah kerangka kerja dalam mendesain model pembelajaran baru dengan menggabungkan tiga aspek utama yaitu teknologi, pedagogi, dan konten (materi pengetahuan). Pengembangan bahan ajar dengan mengintegrasikan materi, model pembelajaran, dan teknologi menjadi kompetensi yang penting dikuasai oleh pendidik sebagai upaya adaptasi terhadap perkembangan revolusi industri 4.0. Bahan ajar perlu diintegrasikan dengan model pembelajaran tertentu sebagai basis kegiatan siswa. Model pembelajaran guided inquiry menjadi salah satu model pembelajaran yang sesuai dengan ruh pendekatan saintifik. Berdasarkan hasil observasi awal dan beberapa penelitian terdahulu, masih belum banyak guru yang mengembangkan bahan ajar berbasis guided inquiry–TPACK. Solusi yang ditawarkan adalah dengan mengadakan pelatihan tentang pengembangan modul ajar berbasis guided inquiry-TPACK. Kegiatan dilaksanakan pada tanggal 16 sampai dengan 19 Juli 2022 dengan peserta sebanyak 21 orang dari berbagai instansi. Kegiatan dilaksanakan secara daring synchronous melalui zoom untuk penyampaian materi dan secara asynchronous melalui Schoology untuk kegiatan praktik penyusunan bahan ajar. Hasil dari kegiatan ini adalah dokumen bahan ajar elektronik yang disusun oleh peserta pelatihan dengan mengintegrasikan TPACK dan kegiatan pembelajarannya berbasis guided inquiry. Kegiatan ini diharapkan dapat bermanfaat bagi pengembangan kompetensi pedagogi guru.

Abstract

The study was conducted in the home garden of Tanen hamlet in Ngargoyoso, Karanganyar, Central Java, Indonesia, which is situated at an elevation of 772 meters above sea level. The existence of Sukuh Temple near Tanen with Keris reliefs shows Keris culture in this region since ancient times. This study aims to identify plant species in the Tanen home garden suitable for Keris culture and understand their potential roles in Keris culture. Sampling was carried out using the cruising method, following the village road. Data on the plants on-site were collected through surveys conducted in the home garden. The plant species were classified with the assistance of The Mountain Flora of Java and www.theplantlist.com. The plants found were determined to be related to the Keris culture. The data were qualitatively analyzed to determine the role of each plant species in Keris culture and quantitatively assessed using the species richness index. The home garden in Tanen comprises a variety of species, with a species richness of 26 belonging to 19 families. Herbs make up 38% of the plant habitus in Tanen's home garden, which also has shrubs (31%), trees (23%), and bushes (8%). The most commonly used plant organs are leaves (24%) and flowers (24%). The potency of plants in the Tanen home garden for Keris culture is: for the name of the plant called in the blade of the Keris; for warangka (sheath) and deder (hilt); for equipment in Keris making; for cleansing agents; for fragrances (fragrant agents); and offering (food ingredients, spices). The primary potential use of plants in Tanen's home garden is for offering.

Abstract

AbstractThis research aims to identify the types of phytoplankton, identify the abundance of phytoplankton, and study the relationship between environmental factors and the abundance of phytoplankton. This research was carried out on January 10, 2023, at the Jenes River, Surakarta. Sampling was carried out at 3 observation stations to identify environmental factors (pH, DO, CO2, salinity, BOD, light intensity, temperature, and brightness). Observations were carried out at three stations, namely upstream, middle and downstream, namely, in the morning (06.00–07.00 WIB) and during the day (12.00–14.00 WIB). Measurements of environmental factors were carried out at the integrated laboratory at Sebelas Maret University, Surakarta. The results of the research showed that the phytoplankton found were 9 families consisting of 11 species with an average abundance of 6,834 individuals/L in the morning day and an average abundance of 13,088 individuals/L during the day. The most abundant phytoplankton in the morning observations was Ulothrix sp. Meanwhile, the most abundant phytoplankton in the afternoon observations was Chroococcus sp. This abundance is also influenced by environmental factors such as pH, DO, Salinity, BOD, CO2, and temperature. The research found that the middle station had the highest phytoplankton diversity index during the day (1.6), possibly because it was indicated to be lightly polluted, allowing the life of many phytoplankton such as Closterium sp. and Quadrigula sp. The highest abundance of phytoplankton in the morning is Ulothrix sp., in the afternoon, it is Chroococcus sp.AbstrakPenelitian ini bertujuan untuk mengidentifikasikan jenis fitoplankton, kelimpahan fitoplankton, dan analisis hubungan faktor lingkungan dengan kelimpahan fitoplankton di Sungai Jenes Surakarta. Penelitian ini dilaksanakan pada 10 Januari 2023 di Sungai Jenes, Surakarta. Pengambilan sampel dilakukan di 3 stasiun pengamatan untuk mengukur faktor lingkungan (pH, DO, CO2, salinitas, BOD, intensitas cahaya, suhu, dan kecerahan). Pengamatan dilakukan di tiga stasiun yaitu hulu, tengah dan hilir sebanyak 2 yaitu, pagi hari (06.00–07.00 WIB) dan siang hari (12.00–14.00 WIB). Pengujian faktor lingkungan dilakukan di laboratorium terpadu Universitas Sebelas Maret, Surakarta. Hasil penelitian menunjukkan bahwa fitoplankton ditemukan berjumlah 9 famili terdiri dari 11 spesies dengan rata-rata kelimpahan 6.834 individu/L pagi hari dan rata rata kelimpahan 13.088 individu/L pada siang hari. Fitoplankton yang paling melimpah pada pengamatan pagi hari adalah Ulothrix sp., sedangkan siang hari adalah Chroococcus sp. Kelimpahan ini juga dipengaruhi oleh faktor lingkungan seperti pH, DO, Salinitas, BOD, CO2 , dan suhu. Penelitian menemukan bahwa stasiun tengah memiliki indeks keanekaragaman fitoplankton tertinggi pada siang hari (1,6), kemungkinan karena terindikasi tercemar ringan, memungkinkan hidupnya banyak fitoplankton seperti Closterium sp. dan Quadrigula sp. Kelimpahan fitoplankton tertinggi pada pagi hari adalah Ulothrix sp., sementara pada sore hari adalah Chroococcus sp.

Abstract

AbstractFive isolates of endophytic bacteria from the roots of klutuk and ambon banana plants produce indole acetic acid (IAA) hormone. However, the evidence of its potential as Plant Growth Promoting Bacteria (PGPB) has not been observed. Therefore, this study aims to determine the effect of bacterial isolate to increase the growth of rice and maize plants. The growth rates of bacterial isolates were measured before the inoculation into the plant root. The root inoculation was performed following a complete randomized design. Root inoculation was carried out using 5 isolates of endophytic bacteria in rice and maize plant seedlings, and the process was repeated 15 times (n=15). The growth of rice and maize plants was monitored from 1st day after planting (dap) to the 14th dap. The collected data were analyzed by student t-test with a significant level of 5% (a= 0.05). The results showed that the logarithmic phase of all isolates was reached at 4 to 16 hours and K10, K25, K35, K111, and A41 isolates increased the height of plants while the K111 isolate can significantly increase the plant height compared to the control. This experiment revealed that the endophytic bacteria from banana plants increase the rice and maize plant’s growth.AbstrakLima isolat bakteri menghasilkan hormon indole acetic acid (IAA) yang berpotensi memacu pertumbuhan tanaman. Namun, bukti empiris potensinya sebagai Plant Growth Promoter Bacteria (PGPB) belum didapatkan. Penelitian ini bertujuan untuk mengetahui pengaruh isolat bakteri terhadap peningkatan pertumbuhan padi dan jagung. Penelitian ini menggunakan metode eksperimen dengan desain rancangan acak lengkap dan setiap perlakuan diulang 15 kali (n= 15). Hasil pertumbuhan tanaman yang diinokulasi dengan isolat bakteri masing-masing dibandingkan dengan perlakuan kontrol. Sebelum perlakuan, tingkat pertumbuhan bakteri endofit diukur sehingga didapatkan fase logaritmik yang cocok untuk dilakukan inokulasi ke akar tanaman. Setelah perlakuan, pertumbuhan tanaman padi dan jagung dipantau dari hari ke-1 setelah tanam (hat) sampai dengan ke-14 hat. Data dianalisis dengan uji t dengan taraf signifikan 5% (α= 0,05). Hasil penelitian menunjukkan bahwa 5 isolat yang berasal dari tanaman pisang mengalami fase logaritmik pada masa inkubasi 4 hingga 16 jam dan semua isolat bakteri meningkatkan tinggi tanaman serta isolat K111 dapat meningkatkan tinggi tanaman secara signifikan dibandingkan dengan kontrol. Penelitian ini mengungkapkan kemampuan bakteri endofit dari tanaman pisang untuk meningkatkan pertumbuhan tanaman.

Abstract

One of the Basic Competencies (KD) in Biology for Indonesian Senior High School is KD 4.12 which reads "Presents observations of the process of mitosis in the onion root and determines the phases it finds". Based on the basic competency test, students are required to have skills in making and observing mitotic preparations of plant tissue with at least using onion. Observation of mitotic division in plant tissues requires skill in making preparations. Making preparations in observing cells and tissues of plants or animals needs staining. Dyes often used in lab work are synthetic dyes. One of the synthetic dyes commonly used is safranin. However, safranin is quite expensive. This limitation requires teachers to look for alternatives to synthetic dyes that are easily found at a more affordable price, namely with natural dyes. One of the plants that has the potential to overcome this issue is beetroot (Beta vulgaris). The purpose of this study was to determine the quality of plant tissue preparations (Allium cepa) stained with beetroot skin (Beta vulgaris) as a natural coloring agent. The research method used was an experimental method with a Completely Randomized Design consisting of two factors, namely the staining time (1 hour, 2 hours, and 3 hours) and the type of solvent (aquades and citric acid 10%). The results of the study were analyzed with qualitative descriptive methods which included contrast and clarity of the preparations. Based on the results of the study, the quality of Allium cepa root preparations using beetroot (Beta vulgaris) skin extract with variations in the type of solvent and duration of staining showed good results on the staining time of 1 hour and 2 hours. The staining time of the preparations can affect the contrast and clarity of the preparations.
