Abstract

This study aims to determine the effect of PBL-based LKPD on the material structure and function of tissue in animals on learning motivation and learning outcomes cognitive learners SMAN 1 Labuhanhaji East. The data retrieval took place in September 2016, with true experiment method with pre-test post-test, control group design which was held in SMAN 1 Labuhanhaji Timur, in the odd semester of academic year 2016/2017. This research was conducted in two classes namely XI IPA 1 as control class and XI IPA 2 as experiment class. Data was collected by questionnaire of motivation, to see the influence of LKPD based on PBL on learning motivation with t-test technique at significant level 0,05. The test results were performed to look at the homogeneity and normality of the data and show that the data is homogeneous and normally distributed. The result of t test shows that thitung ttabel is learning motivation value 3,465 1,685. Conclusion there is the influence of LKPD based on PBL on learning motivation of learners on the material structure and function of tissue in animal in SMAN 1 Labuhanhaji East Aceh Selatan.Keywords: Student Work Sheet, Problem Based Learning Model, Learning Motivation, Structure andNetwork on Animals.

Abstract

Lake Laut Tawar is a volcanic lake possessing high ecological significance and supporting the livelihoods of surrounding communities. Phenological analysis provides an essential framework for understanding plant reproductive characteristics, including inflorescence types, fruit morphology, and seed dispersal strategies. However, comprehensive information regarding the phenological traits of flora in the Lake Laut Tawar ecosystem remains limited. This study aimed to identify flower and fruit types and evaluate the diversity of plant reproductive strategies in the vegetation surrounding Lake Laut Tawar, Central Aceh Regency, Indonesia. A quantitative field survey was conducted using transect-based observations covering 48 plant families, involving species identification and documentation of floral and fruit characteristics. The results revealed that cymose inflorescences and capsule fruits were the dominant reproductive forms, while additional inflorescence types included racemose structures, and fruit types comprised drupe, berry, legume, achene, caryopsis, and polydrupe. These findings indicate diverse adaptive reproductive strategies associated with environmental conditions, pollination mechanisms, and seed dispersal interactions. The observed phenological diversity contributes to vegetation regeneration, supports faunal population stability, and enhances ecosystem resilience and landscape aesthetics. This study provides baseline scientific data to support flora conservation planning and sustainable ecosystem management in the Lake Laut Tawar region.
