"Tujuan dari industri konstruksi adalah bagaimana menciptakan suatu teknologi yang dapat digunakan dengan nyaman dan aman bagi semua orang dengan biaya yang murah dan aman bagi lingkungan. Namun dalam pekembangannya industri-konstruksi telah menyumbangkan limbah yang sangat besar. Banyaknya limbah konstruksi yang dihasilkan menyebabkan dampak yang cukup serius bagi lingkungan. Upaya mereduksi limbah konstruksi merupakan cara yang terbaik dilakukan.
Identifikasi sumber dan penyebab limbah merupakan salah satu tahapan penting dalam usaha mereduksi limbah konstruksi yang terjadi pada proyek konstruksi. Proses konstruksi adalah salah satu pendekatan yang dilakukan, dengan menjabarkan suatu proses hingga bagian terkecil sehingga diharapkan dapat diketahui jenis pekerjaan yang berpotensi menghasilkan limbah konstruksi.
Penelitian ini dilakukan dengan pendekatan survey, melalui angket dan wawancara. Dan hasil analisis deskriptif dan analisis korelasi dapat diketahui bahwa pekerjaan dinding penahan tanah merupakan pekerjaan yang paling banyak menghasilkan limbah, adapun material limbah yang dihasilkan berupa sisa puing adukan dan tanah sisa galian yang menempati urutan pertama dan kedua volume limbah yang dihasilkan pada proses konstruksi basement. Sedangkan faktor pelaksanaan dilapangan merupakan penyebab terbesar terjadinya Iimbah konstruksi berdasarkan Studi deskriptif yang dilakukan."

"Salah satu permasalahan penting dalam pelaksanaan proyek konstruksi, tetapi kurang mendapat perhatian adalah masalah limbah konstruksi. Yang dimaksud limbah konstruksi adalah hasil buangan yang dihasilkan dari rangkaian kegiatan konstruksi rumah, gedung, dam, sekolah, dan struktur lainnya. Limbah konstruksi dapat berupa material seperti kayu, logam, kabel, kaleng, beton, gipsum, dan lainnya. Pengelolaan limbah konstruksi memerlukan suatu manajemen yang dinamakan manajemen limbah konstruksi. Manajemen adalah proses penggunaan sumber daya secara efektif untuk mencapai sasaran. Oleh karena itu manajemen limbah konstruksi dapat diartikan sebagai suatu proses penggunaan sumber daya yang ada secara efektif untuk mengelola limbah yang dihasilkan dari rangkaian kegiatan konstruksi rumah, gedung, dam, sekolah, dan struktur lainnya.
Tujuan yang ingin dicapai dalam penulisan skripsi ini adalah untuk mengetahui penerapan manajemen limbah konstruksi, terutama dalam hal manajemen materialnya, pada pelaksanaan konstruksi jalan layang.
Metode penelitian yang digunakan adalah studi kasus; yaitu proyek Tanjung Barat Flyover dan Raya Bogor Flyover. Pengumpulan data dilakukan dengan cara wawancara dan observasi.
Hasil penelitian menunjukkan pelaksanaan konstruksi jalan layang telah melaksanakan manajemen limbah konstruksi yaitu dalam kegiatan penyimpanan, kegiatan penanganan dan distribusi, manajemen lokasi, seuse dan recycling, serta kegiatan pembuangan (disposal)."

"Industri konstruksi bangunan perlu menerapkan konsep keberlanjutan yang dapat mengurangi dampak lingkungan yang terjadi selama proses konstruksi hingga bangunan tidak terpakai lagi. Banyak ahli menyatakan bahwa konstruksi prefabrikasi bisa menjadi solusi dalam penerapan konstruksi keberlanjutan. Konstruksi prefabrikasi adalah upaya menjadikan elemen bangunan terpecah menjadi komponen atau modul yang dapat diolah secara offsite lalu dibangun secara onsite. Tetapi, pernyataan tersebut perlu dikaji lebih lanjut mengenai keterkaitan antara prefabrikasi dengan keberlanjutan pada konstruksi. Oleh karena itu, kajian ini mencoba mencari tahu keterhubungan antara prefabrikasi dengan keberlanjutan melalui analisis studi kasus yang berlandaskan pada studi literatur. Studi kasus yang diangkat adalah bangunan Tetrapost yang berada di Pulau Untung Jawa, yang diketahui telah menerapkan konsep prefabrikasi. Studi kasus dilakukan dengan observasi pada keseluruhan proses konstruksinya sehingga hasil observasi tersebut dapat menjadi data untuk penilaian yang telah disusun. Hasilnya adalah bangunan Tetrapost merupakan bangunan prefabrikasi yang tidak sepenuhnya menerapkan keberlanjutan pada proses konstruksinya.

The building construction industry needs to apply the concept of sustainability which can reduce the environmental impact that occurs during the construction process until the building is no longer in use. Many experts state that prefabricated construction can be a solution in implementing sustainable construction. Prefabricated construction is an effort to break down building elements into components or modules that can be processed offsite and then built onsite. However, this statement needs to be studied further regarding the relationship between prefabrication and sustainability in construction. Therefore, this study tries to find out the relationship between prefabrication and sustainability through case study analysis based on literature studies. The building that is going to be used for case study is Tetrapost located in Untung Jawa Island. This building is known to have implemented the concept of prefabrication. Case studies are carried out by observing the entire construction process of the building so that the results of this observations can become data for the assessment that has been prepared before. The result is that the Tetrapost building is a prefabricated building that does not fully apply sustainability to its construction process."

Industri konstruksi merupakan kontributor signifikan terhadap masalah lingkungan selama meningkatnya perhatian lingkungan yang disebabkan oleh urbanisasi yang tidak teratur dan ekspansi industri yang cepat. Pemasok hijau dalam konstruksi berkelanjutan memperkenalkan metodologi yang bertujuan mengatasi dampak negatif terhadap lingkungan dan memfasilitasi integrasi praktik konstruksi berkelanjutan di masa depan. Tujuan utama dari penelitian ini adalah untuk mengetahui hambatan dan kriteria pemilihan pemasok hijau dalam industri konstruksi di Indonesia, sebagaimana dipersepsikan oleh kontraktor. Penelitian ini menggunakan dua metode: RII untuk menyelesaikan pertanyaan penelitian pertama dan AHP untuk menyelesaikan pertanyaan penelitian kedua. Penelitian ini menganalisis hambatan yang dihadapi kontraktor saat mengadopsi praktik pemasok hijau, menggunakan metodologi Indeks Kepentingan Relatif (RII). Hambatan-hambatan ini mencakup hambatan ekonomi, teknologi, kesadaran, dan pemerintah. Evaluasi kriteria pemilihan pemasok hijau dari metode AHP didasarkan pada karakteristik perusahaan, tawaran teknis dan komersial, serta aspek sosial-ekonomi. Hasil penelitian mendapatkan pentingnya kriteria ini dalam mempromosikan metode konstruksi berkelanjutan dan meminimalkan dampak lingkungan dalam industri konstruksi di Indonesia.

This undergraduate thesis analyzes obstacles and criteria for green supplier selection in the Indonesian construction industry from a contractor's perspective. The construction industry is a significant contributor to environmental issues during increased environmental concern resulting from unregulated urbanization and rapid industrial expansion. Green suppliers in sustainable construction introduce methodologies that aim to address negative environmental effects and facilitate the integration of sustainable construction practices in the future. The primary aim of this study is to find out the obstacles and criteria for selecting green suppliers in the construction industry of Indonesia, as perceived by contractors. This research employs two methods: RII for solving research question 1 and AHP for solving research question 2. The research analyzes the obstacles that contractors face while adopting green supplier practices, using the Relative Importance Index (RII) methodology. These challenges include economic, technological, awareness, and government obstacles. The evaluation of green suppliers' selection criteria from AHP method is based on firm characteristics, technical and commercial bids, and socio-economic aspects. The results highlight the significance of these criteria in promoting sustainable construction methods and minimizing environmental impacts in Indonesia's construction industry."

ABSTRACT
The concept of disaster management nowadays is risk reductionsparadigm. Each individual, residents are introduced to various threats and vulnerabilities owned, as well as increased capacity in facing any threats. This study aims to assess the risk control model of ammonia gas dispersion.
The designstudy was cross sectional using confirmatory factor analysis (CFA) as the measurement model and structural analysis. Validity and reliability value for Goodness of Fit (GOF) test is good fit for construct of the model. Questionnaires were distributed by cluster, there were626 respondents (risk area 0-2600 meters) divided into 293 and 333 respondents in the inner and outer zones (risk area >1300-2600 meters).
Measurement model produces 5 directly interconnected exogenous variables (environmental, social, economic, biological and capacity condition) to form an endogenous variable risk of ammonia gas dispersion. Environmental conditions consist of danger zone and distance from home to road. Social factors consist of training and job. Economic factors consist of accommodation, salary, assurance and education. Capacity factors consist of hazard knowledge, early warning knowledge, evacuation knowledge and emergency response behavior.Biological factors consist of age >65 year old and family member with chronic disease and disability. The model goodness of fit test result was compatible for RMSEA, CFI, IFI, CN, SRMR, GFI and AGFI. It indicates that the models can describe the ammonia gas dispersion riskformed factors. Social factorscontribute61% of thetotalrisk ofammoniagasdispersion, related toeconomic factors(42%), capacityfactor(36%)andconditionfactor(5.7%).

"ABSTRAK
Serat rayon merupakan polimer alami yang terkandung pada dinding sel tumbuhan tingkat tinggi. Untuk meningkatkan kegunaan serat rayon, pada penelitian ini dilakukan pencangkokan serat rayon dengan monomer metakrilat (MA) dan akrilamid (AAm) dengan metode iradiasi awal dengan media udara sehingga diperoleh serat rayon-g-(PAAm-co-PMA) dengan %G = 95-114% dan %G = 144-179%. Beberapa penelitian telah dilakukan sebelumnya dengan mencangkok gugus akrilamid (F.E. Okieimen 2003), asam akrilat (Istianah, Romlah 2001) serta campuran asam akrilat dan akrilamid (Fatmuanis, Basuki 2000 dan Virlia, Ninda 2003) ke dalam serat rayon. Karakterisasi serat dilakukan dengan FTIR . Pencangkokan MA memberikan puncak serapan 1642.2 cm-1 dan 1202.5 cm-1 yang merupakan rentang karbonil (-C=O) gugus karboksilat dan rentang ?CH3 gugus metil, sedangkan pencangkokan AAm memberikan puncak serapan 1633.9 cm-1 dan 3671.9 cm-1 yang merupakan tekuk amida (-NH2) dan rentang ?N-H. Kapasitas adsorpsi dilakukan dengan metode AES dan titrasi serta selektivitas adsorpsi secara kompetisi dan nonkompetisi. Variasi pH penentuan selektivitas dilakukan pada kisaran 3.0-7.0 dengan buffer asetat. Pada penggunaan serat rayon-g-(PAAm-co-PMA) sebagai adsorben limbah model elektroplating yang mengandung ion logam Ni2+ dan Cr6+(dalam bentuk Cr2O72-) diperoleh hasil bahwa pemisahan kuantitatif dapat dilakukan pada pH sekitar 6.0 karena pada pH tersebut perbedaan penyerapan Ni2+ dan Cr6+ cukup signifikan. Serat kemudian diregenerasi untuk mengetahui apakah serat yang telah menyerap Ni2+ tersebut dapat digunakan kembali atau tidak. Ternyata Ni2+ dapat teregenerasi dari serat sampai 72.75 % (nonkompetisi) dan 88.36 % (kompetisi). Dapat disimpulkan bahwa pada pH 6.0 Ni2+ dan Cr6+ dapat terpisah sehingga larutan keduanya dapat digunakan kembali serta serat yang telah diregenerasipun dapat dipakai berulang.
Kata kunci : elektroplating; Cr6+ ; Ni2+ ; adsorpsi"
