Abstract

Proses Pembangunan jalan berwawasan lingkungan merupakan faktor utama dalam mewujudkan bangunan yang ramah lingkungan dan rendah emisi. Penelitian ini bertujuan menghitung jumlah karbon yang dihasilkan dari penggunaan material konstruksi jalan serta melakukan optimalisasi jenis material rendah emisi karbon. Metode analisis karbon menggunakan rumusan perhitungan. Hasil penelitian menunjukkan total karbon yang dihasilkan sebanyak 146.569,20 KgCO2 atau 145,57 ton karbon. Material semen sebagai filler dan box culver menghasilkan karbon terbesar yaitu 47% atau sebesar 68,54 ton karbon, jika material ini diganti dengan abu batu diperoleh penurunan sebesar 0,59 ton karbon atau sebesar 98%, sehingga secara total akan menurunkan jumlah karbon sebesar 46,37%. Penurunan ini disebabkan perbedaan besaran koefisien karbon semen yaitu 0,83 KgCO2/Kg sedangkan abu batu sebesar 0,008 KgCO2/Kg. Nilai konversi harga karbon yang berlaku di Indonesia sebesar           Rp. 2.040.000,-. Oleh karena itu penggunaan dan pemilihan material dengan nilai koefisien karbon terendah dapat menurunkan jumlah emisi karbon dari bangunan tersebut secara signifikan

Abstract

The learning carried out in class XI MA Hidayatul Insan uses LKPD which is still limited and has not supported the learning needs of students, so that the learning that takes place is not optimal, the learning process is less interactive, inspiring, and less motivating students to actively participate. Teachers have not maximized the use of LKPD that is attractive to students. This study aims to determine the structure, feasibility, and student response to LKPD based on Liveworksheet Cell material. This research was conducted in class XI MA Hidayatul Insan Palangka Raya and will use data collection instruments in the form of interview guidelines and to determine the quality of E-LKPD using validation from materials, media experts, and linguists. Based on what has been described, it is necessary to conduct research with the title "Development of Liveworksheet-Based LKPD on Class XI MA Hidayatul Insan Palangka Raya Cell Material". The results of the liveworksheet-based LKPD Development Research were obtained from evaluations conducted by validators of material experts, media experts, and linguists. The quality of the material presented in the LKPD developed with an average score of 77.65% is included in the eligibility criteria. The quality of the LKPD display developed The average percentage of score obtained 80% is included in the feasible criteria and, the quality of the language presented in the LKPD developed with an average score of 98.57% is included in the very feasible criteria. Based on a small-scale trial, the results of students' responses to liveworksheet-based LKPD products showed a very positive response with 97.65%. Thus, it can be concluded that the Development of LKPD Based on Liveworksheets in Class XI Mahidayatul Insan Palangka Raya Cell Material is feasible and stated to be usable in the learning process.

Abstract

The construction industry is witnessing a rapid and sophisticated advancement in technology and information, which has led to intense competition among construction service providers. One of the technologies that has completely changed the construction sector is Building Information Modelling (BIM). Acquiring proficiency in this approach will boost productivity and enhance time, expense, quality, and environmental friendliness. Nonetheless, there is still a lack of discernible progress in the application of BIM in the construction industry, particularly for contractors and consultants residing outside of Java Island. This research was conducted in the city of Palangka Raya where most of the construction service actors still use conventional methods, this will provide an opportunity to find out the responses and obstacles experienced by local construction service actors regarding the use of BIM in construction work. The results showed that the advantage factor was occupied by the cost and time management sub-factor with a mean value of 4.158 and a standard deviation of 0.449, while the obstacle factor was the BIM support facility with a mean value of 4.422 and a standard deviation of 0.666 as the dominant factor inhibiting the implementation of BIM in construction projects in Palangka Raya City. The government's participation in enhancing contractors' and consultants' capacity to understand BIM through training and competency programs is necessary to foresee this hindrance factor.

Abstract

This study aims to observe Gram-positive bacteria in eco-enzymes produced from the fermentation of peatland plants in Central Kalimantan and to analyze their potential as biotechnology learning resources for developing students’ scientific explanation skills. The research employed a descriptive qualitative method through eco-enzyme preparation, bacterial identification using Gram staining, and analysis of the role of observational results in the learning context. The findings revealed four Gram-positive bacteria, namely Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, and Lactobacillus bulgaricus. The presence of these bacteria demonstrates the active involvement of microorganisms in the fermentation process, which can serve as a concrete example for students to understand biotechnology concepts. These results emphasize that bacterial identification outcomes are not only scientifically valuable but also hold potential as contextual learning resources that support the development of scientific explanation. Through these observational results, students can practice constructing claims, presenting evidence, and connecting them with scientific reasoning. Therefore, this study concludes that exploring Gram-positive bacteria in eco-enzymes derived from peatland plants has the potential to enrich biotechnology learning while simultaneously developing students’ scientific explanation skills.

Abstract

Literasi lingkungan sebagai infrastruktur publik diperlukan untuk memperkuat kapasitas adaptasi dan mitigasi perubahan iklim. Studi ini menganalisis perspektif pemuda Indonesia khususnya dari daerah Kalimantan Tengah dan Nusa Tenggara Timur, dalam upaya memahami tingkat pengetahuan, sikap kritis, serta preferensi aksi dan kesiapan mereka dalam mendukung literasi iklim. Penelitian dilakukan dengan metode Survei kuantitatif–kualitatif (kuesioner online, n = 222). Analisis kuantitatif dilakukan dengan frekuensi dan persentase, dengan jawaban terbuka dianalisis secara tematik untuk mengekstrak gagasan aksi dan narasi lokal. Hasil penelitian menunjukkan: Responden mayoritas perempuan (52.3%) dan kelompok usia dominan 19–24 tahun (63.5%); 74.8% tinggal di lingkungan perkotaan. Dampak yang paling dirasakan adalah kebakaran hutan dan lahan (37.1%), banjir dan kenaikan muka iar laut (33,5%), kekeringan/gagal panen (14.5%), dan sisanya melaporkan beberapa dampak spesifik. Hambatan utama keterlibatan pemuda adalah rendahnya motivasi probasi (53.2%) dan keterbatasan akses informasi ilmiah (34,5%) dan kurangnya dukungan komunitas. Sumber informasi yang paling dipercaya meliputi institusi resmi dan publikasi ilmiah (63.5%); media sosial, aplikasi iklim khusus dan platform pembelajaran digital (Google Classroom, Moodle, dll) banyak digunakan namun akses dan konten kontekstual menjadi kendala. Responden merekomendasikan aksi lingkungan di komunitas, kombinasi edukasi dan kampanye publik, dan advokasi kebijakan berbasis riset. Untuk menjadikan literasi lingkungan sebagai infrastruktur publik efektif diperlukan intervensi kebijakan, penguatan kapasitas lokal, pengembangan aplikasi digital kontekstual, dan ruang partisipasi pemuda dalam perencanaan kebijakan.
