Abstract

Abstrak Pupuk dan pestisida kimiawi merupakan hal penting pada sistem budidaya tetapi jika  penggunaannya berlebih dapat meningkatkan kandungan logam berat kadmium  (Cd) dalam tanah. Penelitian ini bertujuan menganalisis pertumbuhan tanaman kentang (Solanum  tuberosum L.) pada tanah yang terakumulasi logam berat kadmium. Sampel tanaman berasal dari lokasi pertanian kentang Pangalengan Jawa Barat. Parameter yang diukur yaitu kandungan klorofil, biomassa, kandungan logam kadmium dalam tanah dan umbi kentang. Kandungan kadmium dalam sampel tanah dan umbi kentang diukur dengan menggunakan Atomic Absorption Spectrophotometry (AAS). Hasil penelitian menunjukkan kandungan kadmiumpada lahan pertanian kentang telah melebihi ambang batas. Kadmium terakumulasi dalam umbi kentang, tetapi masih berada di bawah ambang batas. Klorofil, berat kering, dan berat basah mengalami kenaikan setiap minggunya (4-10 Minggu Setelah Tanam). Adanya logam kadmium  yang diserap oleh tanaman kentang dapat menghambat pembentukan  klorofil sehingga akan mempengaruhi biomassa tanaman. Kata kunci: klorofil, biomassa, kentang, kadmium Abstract Chemical fertilizers and pesticides are important in the culture system but if the excessive usage may increase the content of heavy metals cadmium ( Cd ) in the soil. This study aims to analyze the growth of the potato ( Solanum tuberosum L.) on the ground that accumulate heavy metals cadmium. Plant samples derived from potato farming locations Pangalengan West Java.The parameters are chlorophyll content, biomass, cadmium  content in soil and potato tubers. The content of cadmium in soil and potato tuber samples were measured using Atomic Absorption Spectrophotometry (AAS). The results showed cadmium content in potato farms has exceeded the threshold. Cadmium accumulates in potato tubers, but still below the threshold. Chlorophyll, dry and fresh weight increase every week (4-10 Weeks After Planting). The presence of the metal cadmium is absorbed by the potato can inhibit the formation of chlorophyll that will affect plant biomass . Keywords: chlorophyll, biomass, potatoes, cadmium

Abstract

Education is a learning activities to develop according to the times, such as freedom to learn which emphasizes 21st century learning. 21st century learning is inseparable from learning in literacy skills, knowledge analysis, and use the tecnology in the learning process. researchers combined learning models with technology to suit the student centered in this study. This research uses collaborative classroom action research with instruments on student learning outcomes from pre test and post test scores.The result of the analysis achievement of student learning outcome seen from the first cycle is 80,56% with an average value of 80,83 and the second cycle with a percentage of 97,22% with an average value of 86,87. From these results it can be seen that the application of a problem based learning using educational media of finding treasure games can improve student learning outcomes.
