Indonesia has a program to relocate its capital from Jakarta to East Kalimantan Province. This is a big and complex problem and is very interesting for Infrastructure & Facility Asset Management. Develop reflection on the case is very good to enrich and to develop IFAM knowledge and science. The first step has been done by developing an overview of several capital relocation cases. This research, the second step, is designated to make observations on the spatial plan of three good capitals. Visiting experience of the authors, enriched by literature study has been conducted. The reseach has main conclusions. It is better to develop a new city on an empty inhabited area. The symbolic aspect of the city is very important. A good plan, development, and control must be applied. The city must be green and intelligent. The capital must be divided into core areas for accomodating government offices and the peripheral area for accomodating residential areas and recreational areas. Well designed vast enough open space and several green parks are needed. The whole city must be furnished with good urban public transport. A good domestic and international accessibility is capital.

Asset Management in general and IFAM specifically is very important. The knowledge and science need to be developed step by step. PTPN-9 can be used as an excellent Case Study. A general overview was developed as a base for studying the AM in PTPN-9. PTPN-9 is a state-owned-enterprise, whose duty is to manage the business of yearly plantations and seasonal plantations (sugar-cane plantations and sugar factories), in Central Java. Practically, all of the yearly plantations and seasonal plantations (sugar factories) were started by the Dutch, since the colonialization era. As the first step, this paper observes the production assets, the product, and the market. As production assets, the enterprise has 15 yearly plantations and 8 seasonal plantations. As products, it has 7 consumption commodities, 10 commercial commodities, 8 agro-tourism objects, and 14 restaurants and coffees. The enterprise sells its products into the international market and the domestic market.

Commuter Train is one of the facilities that must be managed properly, economically and efficiently by the principles of Facility Asset Management. The availability of infrastructure and vehicles for this facility is adjusted based on passenger demand. This requires sufficient knowledge on the travel behavior characteristics, i.e., different characteristics composition proportion. Travel behavior survey requires the appropriate formula or method to calculate the minimum sample size, for this case are proportions of pq, pqr, pqrs etc. Therefore, a search for Minimum Sample Size Calculation Method for the Travel Behaviour Survey is needed. A literature study was employed for this search. This is important because the calculation method for the minimum sample size for proportions pq exists, but for the proportion of pqr, pqrs, etc do not yet exist. The results of the study indicates that the SR Method is the most appropriate method for calculating the minimum number of samples for the case of the proportion of pqr, pqrs, pqrst, etc. The SR Method is developed based on Goodnees of Fit method combined with the Maximum Acceptable Error principle. The combination of the two is named the MAECCL (Maximum Acceptable Error on a Certain Confidence Level) principle.

Nowadays, Infrastructure & Facility Asset Management (I&FAM) is essential in Indonesia. Indonesian Law on State Treasury was decreed in 2014, which makes the term I&FAM still relatively new in Indonesia. Therefore, the researcher must develop about I&FAM studies, such as doing a practice. For example, the ITS Medical Center (MCITS) use as a case for learning I&FAM. The first step is to identify the statement of the function, the service, and the infrastructure & facility. This research used a straightforward method by reading related document and reconnaissance survey. The research produces three principal results, giving medical service for the ITS' community and the surrounding area, and giving another income for ITS. The ITS Clinic occupies a special clinic building of 2 stories high, equipped with a garage, parking lot and a sign. As a facility, the clinic is equipped with a building, the building facilities, standard clinic medical equipment, and an ambulance.

One of the assets of land transportation infrastructure that obtained attention now is the road. Road construction can support the developing economy, industry, trade, people and good mobility, regional development. Management of road infrastructure assets require to prioritize natural resources managements efficiently as possible. Reclaimed Asphalt Pavement (RAP) is the result of dredging material with aggregate gradation condition that are not in accordance with the needs of the gradation envelope. Utilization of RAP as a pavement layer is an effort to converse the use of natural materials. The efficiency aspect of RAP aggregate use needs to be done by determining the road pavement layer that is most appropriate to the condition of the RAP aggregate so that the addition of new aggregates is kept to a minimum. The aim of this study was to obtain a suitable pavement layer determination based on the aggregate gradation of RAP and standard specifications.The method used literature study from previous research and RAP aggregate sieve analysis from national roads in East Java Province. The results showed that the utilization of RAP from national roads based on the RAP aggregate conformance value were AC-WC layer of 82.292%, AC-BC layer of 68.75% and AC-Base layer of 41.667%. Based on the gradation analysis, it is found that the RAP aggregate is best suited for the AC-WC layer, because it requires optimal RAP aggregate and the most efficient of additional aggregate.

Furnishing adequate national public infrastructure is an obligation for the government. Financing the infrastructure is not an easy problem. The main problem are that the NREB cannot finance the investment cost and the NREB capacity is not enough to finance he whole infrastructure needed. If in general the public infrastructure is merely a cost, there are certain infrastructure which can generate revenue. Meanwhile the GDP is far higher then the NREB. So, thinking involving private fund in public infrastructure financing is logical. Thus public infrastructure financing should be a mixture of public and private fund. The activity involving the Private Sector must be in an Attractive Comercial Activity. Thus preferably for revenue generator infrastructure. Revenue can be generated in various form. The basic idea of solutions can be grouped into fully financed by public budget, by a mixture of public private fund, and by fully private financed. Each group has its owned characterisitcs and derivative solution.

Reclaimed Asphalt Pavement (RAP) is the residual waste of pavement that has been damaged or has reached the end of the pavement by using a Cold Milling Machine (CMM). The old aggregate undergoes gradation changes due to traffic loads and weather effects so the gradation is not following the ideal gradation plan. The addition of natural aggregates aims to improve the grading envelope to meet the upper and lower limits of the AC-BC layer requirements. This study aims to determine the optimal composition of the RAP material in terms of Marshall characteristics. The use of RAP material variations is 30%, 40%, and 50% of the total composition of the mixture. This study refers to the 2018 Bina Marga specifications and the Marshall method for laboratory testing. The research steps consisted of material extraction testing, aggregate and asphalt properties, sieve analysis tests for mixed grading envelopes, and Marshall tests.The results of this study are the characteristics of the mixture in terms of Marshall stability for the composition of RAP 30%, the stability value is 1433.3 Kg, RAP 40% is 1621.7 Kg, and RAP 50% is 1920.8 Kg. The greater the composition of the RAP, the greater the stability value, which shows the strong mixed nature of holding vehicle traffic loads
