Abstract

Bivalves are a class of Phylum molluscs which charaterized by soft, nonsegmented body and protected by a pair of shells. These animals are widespread in coastal areas, especially in mangrove ecosystems. Bivalves are suitable to be  used as indicators of aquatic biology because their lives are relatively sedentary and has the ability to respond to water conditions. The purpose of this study was to determine the distribution pattern of Bivalves in the coastal area of Langsa City based on the characteristics of their habitat. Sampling was carried out in March 2021. The method used in this study was the survey method. Determination of the sampling location using the Proposive Sampling method, so that 2 research locations were selected. The collected data was analyzed using the morissita index and dominance index formulas. The results showed that the distribution pattern of Bivalvia in the coastal area of Langsa City was generally classified as a clustered pattern category where the index value of Id>1. The habitat characteristics of the four Bivalvia species are almost the same, namely the texture of the sandy muddy substrate, but different habitat  are found for Anadara granosa, namely the sandy muddy texture with the preference of high salinity.

Abstract

The Auntentik Assessment Instrument is part of the achievement indicator in obtaining information to measure aspects of student knowledge in the learning process. The measurement process carried out for students in the assessment instrument both individually and in groups consists of three affective, psychomotor and cognitive aspects. Ethnobiological studies are part of the understanding of people's culture regarding the knowledge of plants. Science process skills activities are the implementation of an action carried out by students in practicum learning. The basis of the research objectives is to develop an assessment instrument on a high-level botanical practicum learning tool in measuring students' science process skills and measuring feasibility tests and limited tests of assessment instruments in the implementation of science process skills practicum learning activities. The implementation of the method in the research is a development method. The results of this study consist of three aspects of assessment from expert validation, namely aspects of content validity, presentation aspects and language aspects are declared feasible. Meanwhile, the student's response to the assessment instrument was stated to be good to use as a measuring tool in the assessment of students to carry out a high-level botanical practicum.

Abstract

Hutan mangrove memiliki peran dalam mempertahankan fungsi ekologis dan penyangga kestabilan ekosistem daerah pesisir. Aktivitas kegiatan masyarakat dipesisir perairan seperti pelabuhan, jalur transportasi, pemukiman dan pariwisata memberikan dampak terhadap sumbangan jenis-jenis polutan yang masuk kedalam perairan. Jenis tumbuhan mangrove secara alami berpotensi dapat meminimalisir adanya serapan logam berat seperti jenis Buguiera gymnorriza dan Rhizophora apiculata. Penelitian ini dilakukan bulan Mei sampai dengan Juni 2018. Lokasi penelitian di pesisir hutan mangrove Kuala Langsa, Aceh. Metode penelitian ini deskriptif eksploratif dengan mendeskripsikan satuan serapan logam berat Pb, Cu dan Zn pada jenis tumbuhan mangrove dan Fitoremidiasi jenis tumbuhan mangrove. Analisis data dengan Atomic Absorption Spectrophotometer (ASS) dan Fitoremidiasi (FTD), berdasarkan sampel bagian akar, daun  dan sedimen. Hasil penelitian serapan logam pada jenis Buguiera gymnorriza pada akar, daun dan sedimen secara berurutan pada Zn (seng) 5,833 ppm; 0,598 ppm; 6,775 ppm. Cu (tembaga) 0,0008 ppm.

Abstract

Learning media has a very close relationship with the independent curriculum. As a curriculum that gives students the freedom to choose and determine the direction of their learning, an independent curriculum requires appropriate learning media to support and facilitate this freedom. The learning media used in this service activity is virtual laboratory media as a learning media that can be a solution to the problem of learning loss. The aim of this service activity process is to provide an explanation that is presented by presenting material about the importance of technology in learning, introducing examples of technology that can be used in the virtual practicum learning process. To carry out training in creating practical learning media based on simulation and animation media in accordance with the materials contained in science subjects which can be used in online science practicum learning. Carrying out training on creating a YouTube channel to uploading materials and getting YouTube links for materials that have been uploaded on the channel to sharing YouTube links with science teachers through online learning applications used such as Google Classroom. The method used in service activities is the service learning method with 4 activity stages, namely the Investigation Stage, Preparation Stage, Action Stage and Reflection Stage. The results of community service activities at SMA Muhammadiyah Langsa which were given to teachers and students had a positive impact on the use of virtual laboratory media applications to support the Merdeka curriculum
