"The Impact of Designer's Role in Involving Construction Personnel During the Design Phase on the Performance of Construction Project Schedule in IndonesiaThe study by The Business Roundtable's team in the US found that opportunities to reduce project costs and schedules by using existing and new construction technology are lost because construction too often is relegated to operate as a production function separated from financial planning, scheduling, and engineering or architectural design. Significant savings in both the costs and time required to complete the project can be accrued from careful interaction of planning, design, and engineering with construction into the creation of projects. The Construction Industry Institute's (CII) Task Force defines this term as Constructability, which is the optimum integration of construction knowledge and experience in planning, engineering, procurement, and field operations to achieve overall project objectives. By ignoring constructability in design, designer may be saddling the builder with possible construction problems that could lead to delays, inefficient use of resources, out of sequence work and others. This can be particularly troublesome which may have a devastating effect on project schedule and budget. Designer has an important role in building a receptive interface with construction personnel during the design phase. By communicating the design intent to the construction personnel, designer can gain the information he/she needs to improve the constructability of the project. This thesis study the role of designer in involving construction personnel during the design phase to improve the constructability of the project which leads to an improvement project time performance of construction project in Indonesia. A questionnaire survey was distributed to projects designers in Jakarta area. The data obtained was analyzed quantitatively to find the correlations and to make a regression between the role of designer in involving construction personnel during the design phase and the performance of construction project's schedule. The result of this research shows a positive, nonlinear correlation between the interface of designer with construction personnel during the design phase and schedule performance of the project. The main variables are: communicating the design intent to construction and the involving construction personnel from the construction contractor."

"Indonesia merupakan salah satu pemeran utama dalam industri tuna di dunia dengan rata rata output sebesar 289 metrik ton per tahun. Salah satu efek yang disebabkan besarnya output tuna di indonesia adalah jumlah limbah tulang tuna yang dihasilkan. Limbah yang dihasilkan dapat dimanfaatkan sebagai bahan baku utama ekstraksi kolagen. Kolagen merupakan bahan biopolymer yang memiliki banyak aplikasi dalam kehidupan sehari hari serta bidang biomedis. Beberapa penelitian telah melakukan ekstraksi kolagen pada skala lab. Penelitian ini akan membuat simulasi ekstraksi kolagen dengan metode ASC dari limbah tuna pada skala industri. Untuk membuat simulasi tersebut aplikasi utama yang digunakan adalah SuperPro Designer. Simulasi dijalankan menggunakan 4 masukan yaitu 50kg, 100kg, 500kg dan 1000kg. hasil dari simulasi menunjukkan bahwa variasi 1000kg merupakan yang terbaik scara keekonomian dengan dengan nilai NPV, IRR, dan PBP berturut-turut sebesar USD 3,848,000, 35,55%, 46,36%. Analisis secara keekonomian juga menunjukkan bahwa kapasitas produksi harus dimaksimalkan, namun jumlah limbah tuna yang tersedia menjadi hambatan hal tersebut. Terlebih, metode yang lebih optimal perlu dikaji lagi untuk memaksimalkan output kolagen

Indonesia is one of the main players in the tuna industry in the world with an average output of 289 metric tons per year. One of the effects caused by the large output of tuna in Indonesia is the amount of tuna bone waste produced. The resulting waste can be used as the main raw material for collagen extraction. Collagen is a biopolymer material that has many applications in everyday life and biomedical fields. Several studies have carried out collagen extraction on a lab scale. This research will simulate the extraction of collagen using the ASC method from tuna waste on an industrial scale. To make the simulation, the main application used is SuperPro Designer. The simulation is run using 4 inputs, namely 50kg, 100kg, 500kg and 1000kg. the results of the simulation show that the 1000kg variation is the best economically with the NPV, IRR, and PBP values ​​of USD 3,848,000, 35.55%, 46.36%, respectively. Economic analysis also shows that production capacity must be maximized, however the amount of tuna waste available is an obstacle to this. Moreover, more optimal methods need to be studied again to maximize collagen output"

"Saat ini, teknologi ramah lingkungan giat dikembangkan baik skala riset ataupun sudah diaplikasikan dalam kehidupan sehari-hari. Pada proses ekstraksi, pemilihan pelarut yang tepat sangat menentukan perolehan ekstrak. Sebagai pelarut ramah lingkungan, NADES Natural Deep Eutectic Solvent yang merupakan campuran garam amonium kurterner dan hidrogen bond donor HBD memiliki kelebihan: 1 sifatnya dapat diubah bergantung pada pemilihan garam dan HBD sebagai 39;designer 39; solvent, dan 2 bersifat non-toksik dibandingkan dengan pelarut organik. Oleh sebab itu, potensi NADES perlu terus dikembangkan di masa mendatang. Pada perancangan suatu alat ekstraksi dibutuhkan data kuantitatif tentang kesetimbangan fasa dari campuran fluida yang berinteraksi. Penelitian ini bertujuan untuk mengetahui jenis NADES yang terbaik dalam mengekstrak asam palmitat pada minyak sawit dilihat dari koefisien distribusi dan selektifitasnya. Proses preparasi NADES dilakukan pada berbagai rasio mol betain monohidrat dan HBD. Proses ekstraksi dilakukan pada suhu 50 OC dan rasio berat NADES/minyak sawit 1:2 g/g dengan jumlah asam palmitat yang terkandung dalam minyak sawit 5 -w/w, kandungan tokoferol 1000 ppm serta karoten 700 ppm. Pada penelitian ini didapati NADES dengan HBD 1,2-butanediol merupakan jenis NADES yang mampu mengekstrak asam palmitat yang sangat tinggi yaitu sebesar 2.18 didalam larutan. Nilai selektifitas NADES yang tertinggi dengan menggunakan HBD 1,3 propanediol, terhadap minyak sawit yaitu sebesar 26591 dan tokoferol sebesar 5669.

Currently, green technology developed on research even already applied in life. On the extraction process, the selection of appropriate solvent will determine the acquisition extract. As a green solvent, NADES Natural Deep Eutectic Solvent which is a mixture of ammonium salt quartenary and hydrogen bond donor HBD has advantages 1 their nature can be changed depending on the salt type and HBD as 39 designer 39 solvent, and 2 is non toxic than organic solvents. Therefore, NADES potential needs to be developed in the future. In designing an extraction tools needed quantitative data on equilibrium phase of mixture that interact.

This study aims to determine the best type of NADES in extracting palmitic acid on palm oil seen from the distribution coefficient and the selectivity. NADES preparation process by mixing betaine monohydrate and glycerol at various molar ratio. The extraction process work on temperature 50OC and the weight ratio of NADES palm oil 1 2 g g as well as the amount of palmitic acid contained in crude palm oil 5 w w. Content of tocopherol 1000 ppm and carotene 700 ppm.

Diabetes mellitus is a disease that occurs within the prolonged period of hyperglycemia, it will lead to a condition where the body cannot produce insulin properly. To manage high blood sugar conditions, metformin has been used as an oral anti-diabetic medicine. However, the ever-increasing consumption of metformin and obtaining it need a doctor's prescription have grown an interest in alternative solutions. The alternative medicines utilize the phytochemicals present in melinjo (Gnetum gnemon L.) seed extract that have antidiabetic properties. The study effectively simulated the production of melinjo extracts with an ethanol-water solvent using SuperPro Designer v.13. The simulation projected an estimated annual production of 174,197 extract bottles priced at IDR 300,000 (USD 20) per bottle. The composition of active substances per capsule and the financial analysis indicated favorable ratios for investment (ROI of 152%, PBP of 1.03 years, BEP of 69,918 bottles, IRR of 112%, and NPV of IDR 54,376,500,000 (USD 3,531,000). It can be concluded by melinjo (Gnetum gnemon L.) extracts might become a cost-effective alternative medicine, with industrial possibilities for future investment."
