Tumbuhan memiliki manfaat penting dalam kehidupan masyarakat. Pemanfaatan ini penting untuk dikemas dalam bentuk inventarisasi. Inventarisasi memiliki manfaat dalam pengembangan pendidikan lingkungan atau ekopedagogi berbasis kearifan lokal. Penelitian ini bertujuan untuk mengidentifikasi inventarisasi pemanfaatan tumbuhan oleh masyarakat lokal, dan mendeskripsikan kerangka konseptual relevansi hasil inventarisasi sebagai sumber pembelajaran ekopedagogik berbasis kearifan lokal. Penelitian ini dilaksanakan di Desa Paciran, pesisir Utara Kabupaten Lamongan Jawa Timur. Penelitian ini merupakan penelitian kualitatif dengan analisis deskriptif. Pengumpulan data inventarisasi dilakukan melalui wawancara informan kunci, kemudian dilanjutkan dengan analisis relevansi inventarisasi pemanfaatan tumbuhan sebagai sumber pembelajaran ekopedagogik berbasis kearifan lokal dengan pendekatan studi pustaka. Temuan penelitian ini sebanyak 46 spesies tumbuhan dimanfaatkan oleh masyarakat lokal, didominasi pemanfaatan sebagai obat. Informasi tersebut relevan dikembangkan sebagai sumber pembelajaran ekopedagogik berbasis kearifan lokal. Langkah-langkah yang ditempuh adalah merumuskan data potensi daerah dalam hal ini adalah inventarisasi pemanfaatan tumbuhan oleh masyarakat lokal, kemudian data yang tersedia dikembangkan menjadi sumber pembelajaran ekopedagogik melalui berbagai model pengembangan. Indonesia is a megabiodiversity country, one of which is the diversity of plants. Plants have important benefits in people's lives. This utilization is important to package in the form of an inventory. Inventory has benefits in the development of environmental education or ecopedagogy based on local wisdom. This study aimed to identify an inventory of plant utilization by local society, and describe the conceptual framework for the relevance of inventory results as a source of ecopedagogic learning based on local wisdom. This research was located in Paciran Village, north coastal area of Lamongan Regency, East Java. This research was a qualitative research with descriptive analysis. Inventory data collection was carried out through interviews of key informants, then the research was continued with an analysis of the relevance of inventorying the use of plants as a source of ecopedagogic learning based on local wisdom with a literature study approach. This study resulted that 46 plants species were used by local society, dominated by medicinal use. This information was relevant to develop as a source of ecopedagogic learning based on local wisdom. The steps taken were to formulate regional potential data and in this case was an inventory of plant utilization by local society, then the available data was developed into a source of ecopedagogic learning through various development models.","PeriodicalId":31104,"journal":{"name":"Bioeksperimen Jurnal Penelitian Biologi","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82076758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Penelitian ini bertujuan untuk menganalisis motivasi belajar mahasiswa pendidikan biologi dari strata satu (S1) dan strata dua (S2) ditinjau dari pemberian reward selama perkuliahan. Data dikumpulkan menggunakan kuesioner online tentang persepsi mahasiswa secara umum dan khusus terhadap reward yang diadaptasi dari Lloyd (2007). Selanjutnya, data dianalisis secara kuantitatif untuk menjelaskan persepsi dari 190 mahasiswa pendidikan biologi yang terdiri dari 177 mahasiswa strata satu (S1) dan 13 mahasiswa strata dua (S2). Hasil menunjukkan bahwa seluruh mahasiswa pendidikan biologi setuju dan termotivasi untuk belajar ketika diberikan reward saat perkuliahan. Meskipun persentase tipe reward yang diharapkan berbeda, seperti reward nilai sebesar 50%, pemberian semangat/pujian 23%, lalu 20 % berupa hadiah, sedangkan bentuk lain 7%. Selain itu mahasiswa umumnya lebih memilih diberitahu jika ada reward dibanding diberikan secara spontan. Perbedaan spesifik antara mahasiswa S1 dengan S2 terlihat saat pemilihan khusus jenis reward, dimana mahasiswa S1 lebih memilih nilai sedangkan mahasiswa S2 lebih mengharapkan adanya pengayaan materi, pembimbingan, serta pemberian sumber literatur yang dapat membantu tugas mereka. Penerapan reward yang disesuaikan dengan tingkat pendidikan mahasiswa dapat menjadi acuan dalam mendorong semangat belajar mahasiswa selama perkuliahan.  Reward plays an essential role in supporting or increasing student learning motivation because it is believed as one of contributing factors to students' performance in lectures. This study intended to analyze how rewarding students in classes influences undergraduate (S1) and postgraduate (S2) degrees in biology education students' motivation to learn.

Furthermore, 190 biology education students, consisting of 177 undergraduate students (S1) and 13 postgraduates (S2), had their perceptions addressed through quantitative analysis. The results indicated that all biology education students believed that rewards during lectures motivate them to learn. Although the percentage of the type of reward intended varies, such as a reward in the form of a score was 50%, encouragement or praise was 23%, then 20% was in the form of a gift, while other forms were 7%. In addition, students generally prefered to be informed if there was a reward compared to being given it spontaneously.

The components of the yield will be determined by the allocation of photosynthate on rice and the tall phenotype of black rice, which is a significant contributing factor to lodging. The growth inhibitor paclobutrazol prevents the manufacture of gibberellin, which results in the tall phenotype of black rice. The endogenous cytokinin content is high at the beginning of the grain filling and then rapidly decreases after that. The purpose of the study was to compare the effects of paclobutrazol and cytokinin on culm height, internode length, culm diameter, lodging resistance, culm parenchyma cell arrangement, and flag leaf structure. Throughout the inquiry, Cempo Ireng black rice cultivar seeds were employed. The seeds were planted in plastic containers that held 10 kg of soil for growth medium and organic fertilizer, and a random block pattern was used for the experiment's design. At 10 weeks following sowing, paclobutrazol was sprayed as a foliar application at concentrations of 0, 50, and 100 ppm.
