"Seiring dengan perkembangan populasi, urbanisasi dan industrialisasi, kebutuhan terhadap jaringan lalu lintas berupa jalan tol semakin meningkat. Jalan tol dapat memudahkan manusia dalam kehidupan sehari-hari. Akan tetapi dengan melajunya perkembangan proyek infrastruktur tersebut memberikan dampak terhadap konsumsi energi dan polusi lingkungan. Salah satu solusi untuk menangani ini adalah dengan implementasi jalan tol hijau. Melihat bahwa penerapan jalan tol hijau di Indonesia hanya mencapai 2% dilakukan penelitian ini dengan tujuan untuk menganalisis faktor yang mempengaruhi implementasi tersebut dan hubungan antar faktor. Metode peneltian yang digunakan untuk mencapai tujuan adalah validasi pakar, pilot survei dan survei responden. Dengan metode uji PLS-SEM dengan aplikasi SMARTPLS. Berdasarkan hasil validasi pakar ditemukan terdapat 17 indikator yang mempengaruhi implementasi jalan tol hijau di Indonesia. Berdasarkan nilai T-Statistics tahap konstruksi merupakan tahap dengan signifikansi tertinggi. Regulasi mengenai proyek jalan tol hijau, pengalaman dalam mendesain, training terkait metode konstruksi serta apresiasi dari pemerintah merupakan indikator yang paling signifikan dari setiap siklus hidup proyek. Berdasarkan penelitian ini implementasi jalan tol hijau paling signifikan pada jalan tol eksisting yang belum bersertifikat hijau.

Along with population development, urbanization and industrialization, the need for a traffic network in the form of toll roads is increasing. Toll roads can facilitate humans in everyday life. However, the accelerated development of these infrastructure projects has an impact on energy consumption and environmental pollution. One solution to deal with this is the implementation of green toll roads. Seeing that the implementation of green toll roads in Indonesia has only reached 2%, this research was conducted with the aim of analyzing the factors that influence this implementation and the relationship between factors. The research methods used to achieve the goal are expert validation, pilot surveys and respondent surveys with the PLS-SEM test method with the SMARTPLS application. Using PLS-SEM with the help of SMARTPLS application it was found that there are 17 indicators that influence the implementation of green toll roads in Indonesia.  Based on T-statistics, construction stage is the stage with the highest significance. Regulations regarding green toll road projects, experience in designing, training related to construction methods and appreciation from the government are the most significant indicators base of project life cycle. Green toll road implementation is most significant applied in existing toll road."

In line with the rate of population growth in Indonesia, there has been an increase in the number of construction projects to meet the needs of the population. This presents many problems, such as excess cost and time, as well as the resulting large amount of construction waste. One of the solutions offered to deal with this problem is smart construction. Smart Construction is the process of a construction project that utilizes digitalization, networking, intelligence, and technological developments for development. However, the application of smart construction in Indonesia is still small and experiencing several problems. Therefore, this research is aimed at identifying factors and the relationship between factors that can influence the implementation of smart construction in Indonesia. The methods used in this research are expert validation, questionnaire surveys, and data processing using Partial Least squares structural equation modeling (PLS-SEM). The results of this study show that there are six variables that influence the implementation of smart construction in Indonesia: compatibility, accessibility, organizational readiness, funding, knowledge, and market conditions. Variables that have a high level of significance for the implementation of smart construction in Indonesia based on the T-Statistics values sequentially are knowledge, compatibility, organizational readiness, and funding. Influence factor variables affect the views of construction workers on the benefits of implementing smart construction in Indonesia."

Precast concrete is a form of sustainable construction application, which incorporates sustainable aspects into several factors, such as combining an integrated design, efficient use of materials, reducing construction waste generated, reducing disturbance at work sites, and reducing noise. Although precast concrete components have started to be used in Indonesia, their use is still much less than the use of cast in situ concrete. The theoretical framework of Technology, Organization, and Environment (TOE) has been considered as a suitable context for researching the adoption of an innovation in the construction industry. This study aims to identify the factors that influence the intention to adopt precast concrete in Indonesia based on the TOE framework and analyse the relationship between the factors that influence the intention to adopt precast concrete in Indonesia based on the TOE framework. The research method used in this research is expert validation and respondent survey which is processed by Structural Equation Modeling. The results of this study are obtained 6 (six) variables that affect the intention to adopt precast concrete, including: (1) risk perception; (2) costs; (3) organizational readiness; (4) government support; (5) competitive pressure; (6) compatibility. The value of R-Square for the variable of intention to adopt precast concrete is 0.496. Variables that have a high significance level of influence on the intention to adopt precast concrete based on the T Statistics value are (1) competitive pressure; (2) costs; (3) organizational readiness."

The rapid growth of Indonesia's local cosmetics industry will lead to increased market demand which will have social, environmental, and economic impacts. Corporate social responsibility can help improve the life cycle of cosmetic products in every phase, from design to post-consumer use. However, this needs to be implemented by considering all existing aspects so that the execution is fruitful. This study will analyse the critical factors for the life cycle of Indonesian local cosmetic products using the DEMATELbased ANP method. This study uses the assistance of five experts who will help evaluate the factor criteria by filling out a two-stage questionnaire. This study uses the Modified Kappa method to validate factors with a minimum value of 0.4 and the DEMATEL-based ANP method in analysing the importance and influence of critical factors. This research resulted in 28 critical factors in 6 life cycle phases which were validated by experts. There are three factors with a significant weight of influence in the life cycle of local Indonesian cosmetic products, all of which are within the distribution phase namely: shipping and handling regulatory compliance, collaboration and communication with retail partners, and product safety during transportation and storage."

"Dengan hanya melakukan perbaikan jalan ketika luas kerusakan sudah membesar, dana yang dikeluarkan akan menjadi boros dan tidak efektif. Penelitian ini bertujuan untuk mengetahui biaya pemeliharaan untuk jalan lingkar luar Universitas Indonesia dengan menggunakan metode Life Cycle Cost Analysis (LCCA) dan menentukan strategi pemeliharaan jalan yang paling cost-effective berdasarkan analisis biaya pemeliharaan jalan. Berdasarkan tiga skenario pemeliharaan jalan, didapatkan hasil bahwa strategi pemeliharaan jalan yang paling cost-effective adalah skenario pertama berupa pemeliharaan jalan setiap dua tahun sekali memiliki nilai Net Present Value (NPV) terendah yaitu sebesar Rp 23.490.602,00. Hasil perbandingan nilai NPV menunjukkan potensi penghematan biaya sebesar Rp 18.826.750,00 dari anggaran biaya pemeliharaan jalan dengan cara overlay di jalan lingkar luar Universitas Indonesia jika strategi skenario pertama diterapkan.

By simply doing pavement repairs when the area of damage has been enlarged, the amount of cost expended would be wasteful and ineffective. This study aims to determine the pavement maintenance cost for outer ring road of University of Indonesia using Life Cycle Cost Analysis (LCCA) method and determine the most cost-effective maintenance strategies based on the analysis of pavement maintenance costs. Based on three three pavement maintenance scenarios, the result shows thatthe most cost-effective maintenance strategy is the first scenario, pavement maintenance every two years, with the lowest value of Net Present Value (NPV) Rp 23.490.602,00. The comparison result of NPV value shows potential reduced cost Rp 18.826.750,00 from University of Indonesia?s pavement maintenance budget using overlay work if the first scenario strategy is implemented."
