Abstract

Abstract Utilization of Ambon Banana Peel Extract as a Raw Material for Making Herbal Mouthwash, Ambon banana peel extract was prepared in the form of hand rinse or mouthwash. The treatment in making banana peel extract extract into Mouthwash was made into 2 variables, namely variable 1 Ambon banana peel which had been incubated and extracted for 7 days, and variable 2 Ambon banana peel with an incubation period and extraction for 10 days. The Mouthwash formulation is made in a formulation with the main ingredient being Ambon banana peel extract. Mouthwash evaluation carried out was organoleptic test (shape, smell, color, and taste), pH test, antibacterial activity test. The conclusion of this study is that Ambon banana peel extract can be made in the form of mouthwash which is safe for kids. Keywords:  author guidelines; Ambon banana peel, maceration extraction, Herbal Mouthwash  Abstrak Kulit pisang ambon (Musa Acuminata) merupakan limbah tanaman buah pisang yang mana masih mengandung berbagai macam nutrien. Salah satu komponen terbesarnya yaitu tanin dan flavonoid yang dapat digunakan sebagai bahan baku pembuatan antiseptik. Dalam penelitian ini dibuat ekstrak kulit pisang ambon dalam bentuk sediaan pembilas tangan atau Mouthwash. Perlakuan dalam pembuatan ekstrak kulit pisang menjadi Mouthwash dibuat menjadi 2 variabel yaitu variabel 1 kulit pisang ambon yang telah di inkubasi dan di ekstraksi selama 7 hari, dan variabel 2 kulit pisang ambon dengan masa inkubasi dan ekstraksi selama 10 hari. Formulasi Mouthwash dibuat dalam formulasi dengan bahan utamanya adalah ekstrak kulit pisang ambon. Evaluasi Mouthwash yang dilakukan adalah uji organoleptis (bentuk, bau, warna, dan rasa), uji pH, uji daya antibakteri. Kesimpulan dari penelitian ini adalah ekstrak kulit pisang ambon dapat dibuat dalam bentuk sediaan Mouthwash yang aman. Kata Kunci: kulit pisang ambon, ekstraksi maserasi, Handsanitizer herbal

Abstract

Coal Fired Steam Power Plant (CFSPP) Project is a complex project that requires multidisciplinary knowledge in its implementation. As a result, cost overruns often occur in its implementation. In Indonesia, most power plant projects are using EPC contracts (Engineering, Procurement, and Construction). The contractor is fully responsible for any failures that may occur during the work implementation period. The aim of this study is to compare the realization of completion costs for CFSPP projects with Bill of Quantity (BoQ) and the factors that influence deviations. This research was conducted qualitatively based on the data obtained. Deviations are calculated based on the difference between completion costs and BoQ. Discussions and interviews were conducted with Project Managers and Site Commercial and Risk Managers who were directly involved in construction phase to determine the causes of cost overruns. The result is that the actual cost incurred in the CFSPP project is 3x the cost listed in BoQ. There are cost overruns in each work group including Civil Works, Mechanical Works, Electrical Works and Others Works. Indirect cost realization is 29.84% of total completion cost. The factors that influence cost overruns are: (i) Contractors do not understand the details of the work to be done, (ii) Changes in design and (iii) Realization volume exceeds initial planned volume. The results of this study are expected to be input in preparing owner estimate for CFSPP projects and adding new risk factor lists in CFSPP during construction phase.
