<![CDATA[Indonesia has millions island and big part of Indonesia is sea that is rich in marine biological resources and has the potential to be developed and optimized. One of the abundant marine resources in Indonesia is algae. Algae are plant-like protists. Algae have several important compounds, including protein, carbohydrates, fats, minerals and other useful elements. Proteins contained in algae have the potential to be used as antioxidants. In this study, the levels of protein in red and green algae were tested by using the lowry method and testing the antioxidant activity of red and green algae extracts using the Diphenylpicrylhydrazyl (DPPH) method. Algae extraction was done by maceration, which is soaking the sample in low temperature with phosphate buffer saline (PBS) pH 7. From the extraction results it can be concluded that the red algae (Rhodophyta) has the highest protein content of 5.115 ± 0.126% and the lowest protein content in green algae (Chloropytha) as big as 1.686 ± 0.430%. And from the results of the antioxidant activity test showed that all positive algae showed antioxidant activity but the green algae (Chlorophyta) had the highest antioxidant activity of 71.5946 ± 0.01612% with IC50 value 1.6114.]]>

<![CDATA[Energy evaluation is an important means for an organization to be more competitive in the global era. IKE or the intensity of electricity consumption is a term used to evaluate energy consumption in a system (building). IKE value is obtained by comparing the total use of electrical energy in building area. The evaluation process is done by collecting historical data from Kartika Husada Tambun hospital building., such as data of building area, data of the use of electricity, and the budget spent of electricity needs. From the calculation results, IKE value of the Kartika Husada Tambun Hospital in 2016 was 160,73 kWh / m2/ year, the IKE value in 2017 was 166,04 kWh / m2/ year, and 2018 was 142,79 kWh / m2/ year. This result is in the efficient category because it does not pass the IKE standard for electricity for a hospital building of 380 kWh / m2 per year. For cost savings the author recommends the application of energy-saving technology]]>

<![CDATA[Increasing business opportunities from an economic aspect that includes the financial performance of the Refinery Unit VI is very important to manage. Good financial performance will support the company's business continuity, and also have a positive impact on stakeholders. Refinery Unit VI's commitment to improving financial performance is very high, and strives to achieve predetermined key performance indicators (KPI). Refinery Unit VI measures the achievement of KPI regularly every quarter as part of the evaluation. Targets related to current economic performance are the achievement of KPIs on Refinery Gross Margin and Net Margin. The person in charge for recording and reporting financial performance is under the Financial Function. Refinery Unit VI uses Internal Control over Financial Reporting (ICoFR) to control financial reports, where each function that has the authorization uploads it on the ICoFR web system. In 2017, Refinery Unit VI succeeded in 100% compliance with the IcoFR. The realization of the Refinery Unit VI financial performance from 2015 was always above the target despite fluctuations in product prices. This is a good thing, supported by the achievement of the increasing Gross Refinery Margin and Net Margin from 2015–2017. Refinery Unit VI has continuously succeeded in improving financial performance and achieving the highest Gross Refinery Margin among all Refinery Units owned by PT Pertamina (Persero). The installation of SPM and subsea pipelines is the target of increasing the Refinery Unit VI development program.]]>

<![CDATA[Pengukuran Neutron Porosity pada sumur terbuka (Open Hole) ditujukan untuk mengukur indeks hidrogen yang terdapat pada formasi batuan. Indeks hidrogen didefinsikan sebagai rasio dari konsentrasi atom hidrogen setiap cm3 batuan terhadap kandungan air murni pada suhu 75oF. Neutron Porosity log tidaklah mengukur porositas sesungguhnya dari batuan, melainkan yang diukur adalah kandungan hidrogen yang terdapat pada pori-pori batuan. Secara sederhana, semakin berpori batuan semakin banyak kandungan hidrogen dan semakin tinggi indeks hidrogen. Sehingga, shale yang banyak mengandung hidrogen dapat ditafsirkan memiliki porositas yang tinggi pula. Untuk mengantisipasi uncertainty tersebut, maka pada praktiknya, interpretasi porositas dapat dilakukan dengan mengelaborasikan log density logging. Pengukuran diatas dilakukan pada sumur terbuka (Open Hole) untuk mengetahui respon dari litology, salinity, tipe fluida dan lain-lain. Sedangkan, pengukuran Neutron pada sumur tertutup (Cased Hole) akan sulit dan membutuhkan alat yang khusus. Pada Tesis kali ini penulis ingin memberikan suatu metode penilian formasi dengan mengunakan alat Reservoir Tool Monitoring (RMT) yang dapat bekerja di dalam casing maupun di dalam tubing. Kata Kunci : Alat Pulse Neutron Logging, Hidrocarbon dalam Tubing]]>

<![CDATA[The accumulation of ice on the aircraft's wings can cause a decrease in the aerodynamic properties of the aircraft, increase in weight, and it is difficult to control the aircraft so that it affects aircraft safety. Icing handling on aircraft is growing. One of the newest systems being developed is electrical anti-icing. Therefore, the researcher designed a prototype of an anti-icing electrical wing on a commercial aircraft with advantages in terms of maintenance and lighter components. The purpose of making this prototype is to design an anti-icing electrical wing in the form of a prototype and can be used as an anti-icing. The prototype consists of three parts, namely input, control unit, and heating element. The heating element working system is by attaching the heating element to the surface of the wing, so when the tool is active through the controls, the heating element will work with an indication of the LED on. After testing the Prototype electrical anti-icing function that has been made, it can be used as a de-icing that removes icing that has already frozen on the leading edge.]]>
