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.
