<![CDATA[Project Management must meet the performance criteria of timeliness and budget control agreed between the project owner, contractor and supervisor. However, the level of uncertainty in the project implementation process is very high and causes delays and over budgeting. The Village Nongkojajar is a Proposed Integrated Agropark Project as a result of the revitalization of the non-productive land of the Horticultural Seed Farm owned by the Government of East Java Province. The Landscape Architecture Project has a Creative Value Chain which is divided into Creation - Implementation - Management. Therefore scheduling and controlling the project becomes important in order to to estimate working time and the project remains in accordance with the predetermined project timeline and whenever corrective action is needed. The relevance of Project Management in this research is that with high project problems, require a good planning process. The Project can be completed quickly than the specified time and more cost effective. Critical Chain Project Management (CCPM) is one method for completing and preparing projects that focus on the resource requirements for implementing projects by adding project buffers, feeding buffers and resource buffers. By analyzing using CCPM, researchers can look for optimization and control in implementing project scheduling.]]>

<![CDATA[Public space is one of the important components in the city and participates in improving the quality of life of the people in a city. The city of Surabaya as the capital of East Java with high public space development needs, often the development of public space is more concentrated in the city center. The Public Space of Menanggal Tourism Road located on the border of Surabaya City and Sidoarjo Regency is experiencing a phenomenon that causes a decrease in the image of the region and abuse of the function of public facilities. Behavior of users of public space at the time of the phenomenon is the key to the occurrence of the problem. Therefore an appropriate theoretical approach is needed to understand the phenomenon as a whole. Behavior setting is an approach that connects activity patterns and behavior patterns in a physical environment that is used to understand the phenomenon. This research uses naturalistic paradigms and qualitative strategies with data collection techniques using observation and in-depth interviews. To identify the aspects that most influence on the formation and continuity of the phenomenon of the Tourism Road Region to date these data, data analysis using the Miles and Huberman model is used. The results showed that the affective meaning and activity system were the most influential aspects in the continuity of the phenomenon. These aspects can be used as a basis for developing concepts to overcome the problems that arise during the phenomenon.]]>

<![CDATA[Domestic space is where basic human needs are accommodated and understood to the function and its inhabitants. The basic understanding of using domestic space is human activities as a system of activity and areas as a system of settings. However, visual representation techniques in architecture have led to the discriminatory practices towards visually impaired who have limitations on the sense of sight as a primary tool in spatial perception. Thus, studies are necessary to explore the use of domestic space by visually impaired. This paper aims to study the experience of people with visually impaired doing their activities and using a domestic architecture based on the cognition and percetption of their senses. This phenomenological research is studied at the natural setting of domestic housing from the perspective of women with visual impairment who live in Surabaya. The participants are chosen who have actively and independently carried their daily activities in domestic space. The results of this study show women with visual impairment have a specific system of activities and system of settings related to how the senses affect the spatial behavior of visually impaired in accommodating their activities. By doing so, they are able to compromise and create a friendly and accessible domestic environment.]]>

<![CDATA[Oil and gas companies, contractors and suppliers, under the regulation by the Ministry of Energy and Mineral Resources (EMR), must implement local content implementation in procuring materials and services for oil and gas activities. Company NJH, as one of Production Sharing Contractors, faces problems in the inefficiencies of implementing the local content policy. Three main problems became apparent: unrealistic roadmap implementation, unstandardized contractor performance, and NJH’s human reso urces constraints. Qualitative methodology through interview sessions is used to analyze the current situation within NJH to understand the underlying issues, identify alternative solutions and formulate business solution proposal. Fishbone analysis is used to find the root cause of the inefficiencies. PDCA cycle analysis is also used to formulate business process improvement. The formation of a market research team is recommended to help resolving the roadmap implementation inefficiencies. The goal is to analyze the current SKK Migas PTK 007 Revision 4’s (PTK 007) roadmap adoptability and formulate optimized roadmap to be more practical to contractors and suppliers. A guidance program to support contractor’s documentation format and standards combined with the hiring of local content experts are also recommended as business solution with a goal to expedite verification processes.]]>

<![CDATA[PT. XYZ is a company engaged in fashion which manufactures and sells its own products to consumers. The company sells through various online media including its own website and several marketplace media. However, their consumers make more online purchases through the marketplace than the website, which makes it difficult because the company can only use purchases from the website to obtain complete customer data needed to explore customer behavior. This research will be done using the Fuzzy QFD method to improve the quality of online sales service through the website based on the identified weaknesses of the company website that causes consumers to avoid making online purchases through the website. Fuzzy QFD is a QFD method integrated with fuzzy logic which aims to reduce the vagueness or obscurity of subjective judgments to improve calculation accuracy. The results of this research are 5 technical requirement from FQFD 1st iteration and critical part from 2nd iteration which are expected to produce recommendations needed by company to improve the quality of online sales services through its website based on a more objective and accurate data.]]>

<![CDATA[This research is focused on analyzing strategies for developing SP well production in the B Flowstation offshore platform. The development in question is the construction of platforms and SP gas well production facilities based on the application of the SP gas well production operation mode to the existing Bravo Flowstation production system. The application of the SP well production operation mode will determine the design of the production facility and the amount of investment the company has to operate the SP well. The mode of production operation also affects the continuity and stability of SP gas well production in meeting the company's production targets. Based on seismic results and studies from the company that wells have capacity of 53.5 BCF with a gas production rate of 30 MMSCFD and is capable of producing for 6 years. Incorrect application of operating modes has the potential to cause premature production, which means that production from the well cannot last for 6 years. That is because the occurrence of water coning which has an impact on gas production is hindered by the rate of water production. In addition, the application of the operation mode also affects the continuity of gas well production. Gas production activities may be halted due to production shutdowns due to a mismatch of the SP well production line technology design that is applied to an existing production system. The cessation of SP well gas production activities can also be caused by operational activities such as maintenance activities. From the potential problems that arise, a qualitative analysis is needed by considering every aspect of the problem. With the complexity of things that must be considered in the production development strategy used the AHP (Analytic Hierarchy Process) method. 4 alternative choices of SP well operation modes are determined by the expert. The alternatives include: high pressure mode; low pressure mode; medium pressure mode; and combine high low pressure mode. Criteria identified by the expert include: technology; capital costs; the impact of existing production; operating costs; decline reservoir. From the data obtained in the field as a reference for experts to determine the weighting in the AHP method, the dominant alternative is the development of SP wells based on the combining high low pressure operation mode. The high low pressure operating mode provides continuous production without being affected by existing production processes and has the potential for a medium for water coning. With a sizeable investment the SP well development strategy can be on target in production and on return on investment.]]>

<![CDATA[Mangosteen (Garcinia mangostana Linn) is one of the most well-known plants in Indonesia. Mangosteen contains many derivatives of oxygenated and prenylated xanthones from phenolics which exhibit diverse biological activities such as antioxidants, antimalarials, anti-allergies, anti-tumors, antiviral, antibacterial, anti-inflammatory, anti-fungal, anticancer, and antidiabetic. Modification of xanthone compounds is known to increase antidiabetic activity and it is known that α- and β-mangostin acetylated can be produced from the modification of α- and β-mangostin using acetic anhydride. In this study, as many as 1.43 grams (1.59%) of the γ-mangostin compound were successfully isolated from the ethyl acetate extract of mangosteen pericarp. Modification of γ-mangostin through the acetylation reaction produces acetylated γ-mangostin in the form of 3,6,7-tri-methylester-γ-mangostin as much as 32.9 mg (63%). Antidiabetic test results showed γ-mangostin had an IC50 value of 8.55 μM, while the IC50 value of 3.6.7-tri-methylester-γ-mangostin was 1.82 μM. Acarbose as a positive control has an IC50 value of 4.48 μM. This shows that modification can increase antidiabetic activity.]]>
