Abstract

This study aims to develop virtual laboratory learning media based on discovery learning of the immune system and to determine the feasibility of a virtual laboratory learning media based on discovery learning of the immune system. This study is a research and development adopting the 4-D device development model. In this study the design of the 4-D development was modified into 3 steps (3-D) namely Define, Design, and Develop. The study was conducted at one of the state high schools in Sragen Regency. The research subjects were divided into two, namely limited trial subjects and field trials determined using simple random sampling. The data was analized by using qualitative and quantitative techniques. The results of the study stated that virtual laboratory media based on discovery learning of immune system was created by using adobe animate CC 2017 with a design concept writing, images, animation, and video with characteristics of discovery learning models and virtual laboratory media based on discovery learning of immune system feasible to be used in learning based on validity tests from several experts with a very valid level of validity.

Abstract

Apocynaceae merupakan salah satu famili tumbuhan tingkat tinggi yang memiliki keanekaragaman sekitar 2.000 spesies yang tersebar di daerah tropis dan subtropis. Salah satu tempat eksplorasi keanekaragaman spesies anggota famili Apocynaceae adalah di Kampus Universitas Sebelas Maret, Surakarta yang memiliki potensi sebagai pertumbuhan berbagai tanaman tingkat tinggi. Penelitian ini bertujuan untuk mengetahui keanekaragaman dan hubungan kekerabatan spesies anggota famili Apocynaceae berdasarkan karakteristik morfologi di Kampus Universitas Sebelas Maret, Surakarta. Metode penelitian yang digunakan adalah metode eksplorasi.  Sampel yang didapat kemudian diidentifikasi berdasarkan 15 ciri karakteristik morfologi menggunakan kunci determinasi Flora of Java, lalu mendeskripsikan karakter morfologi sesuai fakta di lapangan. Hasil penelitian ditemukan sembilan spesies anggota famili Apocynaceae yang terdiri dari lima genus berbeda yaitu spesies Tabernaemontana divaricata L., Tabernaemontana corymbose L., Catharanthus roseus L., Catharanthus lanceus L., Cerbera manghas L., Plumeria acuminata L., Plumeria inodora L., Plumeria alba L., dan Adenium obesum L. Analisis klaster berdasarkan parameter 15 ciri karakter morfologi yang dilakukan menggunakan metode pengelompokan UPGMA (Unweighted Pair Group Method using Arithmetic Average) menghasilkan dua klaster. Hasil analisis komponen utama karakter morfologi yang paling mempengaruhi dalam hasil pengelompokan spesies famili Apocynaceae adalah tipe percabangan, warna bunga, bentuk daun, posisi mahkota bunga, tipe perbungaan, pangkal daun, habitus, bentuk buah dan biji.

Abstract

The demand for environmentally friendly textiles has driven the increasing use of plant-based natural dyes, particularly in ecoprint batik products. However, local knowledge regarding dye plant species, utilized plant parts, and dyeing techniques has not been systematically documented. This study aims to examine the utilization of natural dye plants in ecoprint batik fabric production within the GodhongKoe and Cindelaras communities in Surakarta City, Central Java. The research employed a descriptive method using primary data obtained through observations, questionnaires, and interviews with artisans selected through purposive sampling. Data were analyzed qualitatively and quantitatively by calculating the percentage of plant organ usage. The results showed that both communities utilized 10 plant species each. Leaves were the most dominantly used plant organ, accounting for 60% of total usage, due to their easy availability and effectiveness in producing natural patterns and colors. In addition, stems and bark were utilized as sources of strong pigments and natural fixatives. This study concludes that ecoprint practices reflect the utilization of local plant diversity based on ethnobotanical knowledge. These findings contribute to the preservation of local knowledge on the use of natural dye plants while supporting the development of environmentally friendly creative industries based on local biological resources.
