Introduction
Indonesia as an archipelagic country has potential problems that become a threat in the national territorial waters (Putra, Hakim, Pramono, & Leksono, 2017).The threats include violations of law covering armed robberies, human smuggling (illegal immigrants), smuggling of goods, illegal fishing, marine pollution, illegal exploration and exploitation of natural resources, as well as other violations in water areas (Poerwowidagdo, 2015).On the other side, the Indonesian Navy (TNI AL ) is a main component to protect maritime security (Susilo, Ahmadi, Suharyo, & Pratisna, 2017).The TNI AL posture is structured on the basis of several components in the integrated fleet weapon system, consists of: Warship, Airplanes, Naval Base and Marine Corps (Yogi, Rizal, Ahmadi, & Suharyo, 2017).
The aim of paper is to formulate a posture of Indonesian navy development strategy to encounter the threat of national maritime security.This paper uses integrating SWOT analysis and Interpretative Structural Modeling (ISM) to formulate the development strategy.SWOT analysis uses to identify and formulate some strategy of Navy posture capability.ISM method uses to identify and map relationships between strategies.
To support the research, this paper has many literatures.SWOT analysis uses to applying the priority model of engineering faculty development strategy (Živković, Nikolić, Djordjević, Mihajlović, & Savić, 2015).SWOT analysis to formulate the development strategy of traditional shipyard industry (Lumaksono, 2014).SWOT analysis to provide an appropriate strategic analysis to plan the relocation of the naval base (Yogi, Rizal, Ahmadi, & Suharyo, 2017).SWOT to prioritization of strategy for viticulture development (Dibokić, Nikolić, Djordjević, Panić, & Živković, 2017).
The literatures about Interpretative Structural Modeling (ISM).ISM for analyzing interactions between barriers to just-in-time (JIT) production operations (Jadhav, Mantha, & Rane, 2015).ISM to analysis of core industry competencies in Pekalongan City (Paramitha & Nurcahyo, 2018).ISM uses for identification of readiness in implementing business Intelligence project (Farrokhi, Pokorádi, & Bouini, 2018).ISM uses to identify the drivers of travel / tourism growth and build relationships between enablers (Roy & Misra, 2016).ISM uses to study various aspects and correlations between youth and sustainable rural development (Panackal & Singh, 2015).
This research is expected to contribute to the science of military operations research in the concept of strength development and ability.
This paper is organized as follows.Section 2 explains the basic concept the model of strategy development.Section 3 gives result of paper.Section 4 describes the analysis of development strategy for Indonesian Navy (TNI AL) posture.Section 5 presents the conclusion of paper.

Navy Ability (Posture of Navy)
The development of posture is projected towards a regional maritime with an active principle that is defensive.This posture is designed to address possible threats, actual problems, and to support defense forces.There are many components in the posture, such as (Ministry of Defence, 2015): 1. Strength.
The main components of strength based on Integrated Fleet Weapon System consist of Warship, Airplanes, Naval Base and Marine Corps.2. Capability.
The capabilities of the Navy are designed for intelligence, diplomacy, defense, security, regional empowerment and support capabilities.3. Deployment.
The deployment of the Navy includes organization, strength and ability.This is aligned with the establishment of a fleet command organizational structure, including centralized, territorial and support unit strength.

SWOT Analysis
SWOT analysis is an effective strategic planning tool for analyzing the organization of internal and external influences (Gürel & Tat, 2017).SWOT analysis consists of internal and external factors.Internal factors (strengths, weaknesses) are used to test assets within an organization (Marić & Ilić, 2012).External factors are used (opportunities, threats) to investigate factors in the environment beyond the organizational control that affect organizational performance (Gürel & Tat, 2017), (Njoroge, Ongeti, Kinuu, & Kasomi, 2016).Information obtained can be integrated in different matrix combinations of the four factors in determining strategies for long-term progress (Yuksel & Dagdeviren, 2007;Živković, Nikolić, Djordjević, Mihajlović, & Savić, 2015).
The SWOT analysis shows the right strategy in four categories (SO, ST, WO and WT) (Dibokić, Nikolić, Djordjević, Panić, & Živković, 2017).Strength-Opportunity (SO), this strategy takes advantage of opportunities by using existing strengths.Strength-Threat (ST), this strategy uses the strength to eliminate or reduce the effects of threats (Marić & Ilić, 2012).Weakness-Opportunity (WO) strategies are used to take benefit from opportunities by external environmental factors with fixing the weaknesses.Last, Weakness-Threat (WT) strategies are used to reduce an impact from threat with fixing the (Dibokić et al., 2017).

Interpretative Structural Modeling (ISM)
The interpretative structural modeling (ISM) used for ideal planning, is an effective method because all elements can be processed in a simple matrix (Wang, 2015).ISM was first proposed by Warfield in 1973.The interpretative structural modeling is a methodology that aims to identify the relationship between a particular item, which defines a related problem or issue (Attri, Dev, & Sharma, 2013) and a suitable modeling technique for analyzing the influence of one variable on another variable (Solke & Singh, 2018).ISM has been well proven to identify structural relationships among system-specific variables.The basic idea is to use practical experience and expert knowledge to parse complex systems into multiple sub-systems and build structured structural models (Firoz & Rajesh, 2012).The ISM-based approach is one of the versatile and powerful techniques that have been used to solve complex multi-factor problems.ISM is interpretative, since the group assessment selected for the study determines whether and how the related variables (Balaji, Velmurugan, Prapa, & Mythily, 2016).There are procedures or stages in the use of the ISM method, such stages as : 1. Identify elements of a system.The system elements and sub-elements of the system are identified.This step can be done through research, brainstorming or other.

Development of Structural Self Interaction
Matrix (SSIM).The development of an interpretive structural model begins with the preparation of a structural self-interaction matrix, indicating the direction of the contextual relationship between elements.

From the self-interaction matrix (SSIM), the relational indicator is converted to binary numbers 0 and 1 to obtain a square matrix, called the reachability matrix (Hussain, 2011).Source: Author

Strategy Formulation
The analysis of Navy ability development strategies using SWOT (Strength, Weakness, Opportunities and Threats) is maximizing Strength and Opportunities, while minimizing Weakness and Threats.The data taken from interviews and observations with six experts.The results of the SWOT analysis are described as follows:

From the Canonical matrix table above, it is found that the variable (SO)1 is the sixth iteration.(SO)1 at the level VI.Variables (SO)3 and (WT)1 are the seventh iteration.(SO)3 and (WT)1 at the level VII.
The next step, create a model produced by the ISM to solve the problem, in this case the development of posture ability of the Indonesian Navy.From the model, then made implementation strategy based on level (level) that formed.This model can provide the process of the program or activities that will be done first to the final stage.

Discussion
The main purpose of the ISM method is to classify the elements under investigation, according to the driver and dependency.From Reachability matrix, it got the value of Driver Power (DP) and dependence value (D)  From the driver and dependency diagram shown in Figure 4, it is explained that no driver has a strong linkage (sector III).Furthermore, in sector I there are six drivers, namely (WO)1; (SO)1; (ST)3; (WT)2; (ST)2; (SO)2.(ST) 1 is in sector II.In sector IV there are 3 drivers (SO) 3; (WO) 2; (WO) 1.
According to the results of data analysis with the ISM method, it shows that the strategy (ST)1 is a key element in the strategy of developing the posture of the Navy.This is highly relevant to threats to existing maritime security.The key strategy is an increase of state budget percentage for the maritime sector in the development of Navy ability.

Conclusion
Based on SWOT analysis, there are several internal factors that become strengths and weaknesses as contained in the table upon.It has eight points for strength analysis factor and seven points for weakness analysis factor.It has seven points for opportunity analysis factor and nine points for threat analysis factor.The total strategy that has been formulated is 10 (ten) sub strategies which determine the development of the Navy posture abilities.
