Abstract

Green hotel muncul sebagai salah satu solusi atas permasalahan lingkungan yang terjadi. Akan tetapi, apresiasi positif terhadap pelaksanan green hotel masih diperlukan. Penelitian ini mengkaji apakah green hotel sebagai salah satu solusi permasalahan lingkungan mendapatkan apresiasi positif dan diminati oleh pengunjung hotel. Penelitian dilakukan dengan metode deskriptif kualitatif dengan mengajukan kuesioner pada mahasiswa Yogyakarta dan Jawa Tengah terkait pengalamannya menginap di Hotel Yogyakarta. Berdasarkan hasil penelitian didapat bahwa 34,28% sangat setuju lebih memilih tinggal di green hotel yang peduli dengan persoalan lingkungan, 57,14% setuju, 5,71% tidak setuju, 2,86% sangat tidak setuju. Selain itu, minat untuk dapat tinggal di green hotel sangat tinggi dengan persentase 28,57% sangat berminat, 65,71% berminat, 5,72% tidak berminat, 0% sangat tidak berminat. Sehingga green hotel sebagai solusi atas permasalahan lingkungan mendapat apresiasi positif dan minat yang tinggi dari calon pengunjung dan pengunjung hotel dan memiliki potensi besar untuk berkembang lebih baik.

Abstract

The curriculum is the basis for implementing the learning activity method, and the practicum method can be one way to achieve learning outcomes. The acid-base practicum learning method in chemistry learning uses indicators to identify acid-base compounds. The indicator that can be used is the use of natural materials with purple cabbage. Purple cabbage has a distinctive color, namely purple, which is caused by the presence of a color pigment, namely anthocyanin. This study is a qualitative descriptive study with data collection techniques of triangulation data (literature study, observation, and experiment). This study aims to optimize the manufacture of indicator paper from purple cabbage, and to analyze the feasibility of its application experiment through curriculum analysis and learning outcomes. The methods used are maceration, anthocyanin test, indicator paper success test, indicator paper stability and durability test and analysis of learning outcomes. The results obtained are that purple cabbage indicator paper can be used to identify acids and bases effectively, especially strong acid and strong base compounds and can be used in chemistry learning to achieve learning outcomes. The stability and durability test of purple cabbage indicator paper can be used for 15 days of storage at room temperature.

Abstract

Chemistry learning in vocational schools is often limited to general concepts and lacks connection with students vocational expertise, making it difficult for them to apply theory to practice in agricultural product processing. This study aims to develop acidbase teaching materials using the four-step teaching material development (4STMD) method for students in the agricultural product processing agribusiness program at vocational high schools. The research responds to the lack of curriculum-aligned and contextually relevant resources that integrate chemistry with vocational practices. The study employed development research (DR), focusing on the first two stages of the 4STMD method: selection and structuring. In the selection stage, materials were designed based on basic competencies 3.5 and 4.5, producing eight learning indicators and sixteen concept labels. Acidbase concepts were compiled from national and international textbooks and contextualized with agricultural applications, such as pH control in fermentation. In the structuring stage, concept maps, macro structures, and three levels of representation (macroscopic, microscopic, and symbolic) were developed to link chemical theory with agricultural practices. The draft materials were refined through expert review to ensure clarity and scientific accuracy. The results indicate that the developed teaching materials are systematic, scientifically valid, and relevant to the curriculum. They also integrate substantive and pedagogical contexts that support students vocational learning needs. This study shows that the 4STMD method is effective for producing chemistry teaching materials that are structured, contextual, and applicable, thereby enhancing the relevance and quality of chemistry education in vocational high schools
