In investing, there is definitely a risk, as well as the concession of toll roads. Risk analysis is used to anticipate losses due to an element of risk at each investment stage. The results of the analysis show that the highest risk probability for the Solo-Ngawi toll road is land availability and the influence of weather during development and the highest risk impacts are land availability, the potential for revolution in state governance. Based on the results of the analysis, the investment risk level of the Ngawi Solo Toll Road is included in the moderate risk category, so there is a need for cooperation in risk assurance by the Insurance Agency so that the risk level can be reduced to be lower than before.

In this paper, risk acceptability evaluation and risk weight and improved risk level were added in original risk matrix method according to its shortcomings and practicality and need of evaluation of investment risk in international engineering project. A model based on improved risk matrix method was put forward to evaluate investment risk in international engineering project. Firstly, investment risk evaluation index system of international engineering project was established. Secondly, level of risk factors were decided by risk impact level and risk probability scope, borda ordinal value was calculated to form judgment matrix, analytic hierarchy process was introduced to calculate risk weight. Synthetic risk level was determined by product of quantized value of risk level and corresponding risk weight. Risk acceptability evaluation was decided by risk impact level and risk probability scope. Finally, a case study was presented to verify the feasibility of the model which would provide a reliable basis for the investment decision.

The Jakarta inner ring toll road is a toll road that surrounds the inner city of Jakarta. Due to the dense number of vehicles and traffic congestion on the existing inner-city toll roads, the DKI Jakarta Provincial Government plans to increase the number of inner-city toll roads to 6 sections. The project development begins with Section 1A, namely from Kelapa Gading - Pulo Gebang. At present development is still at the stage of foundation work where progress in October 2019 only reached 80.97% of the target of 100%. The work has been delayed and has been extended 2 times. From these problems, this study was conducted to analyze the high risks that affect the time performance of foundation work and corrective and preventive actions. In this study data collection was carried out by distributing 4-step questionnaires, namely expert validation, pilot survey, respondents, and final expert validation. Risk ranking is analyzed using MS. Excel is based on a probability and impact matrix table that aims to determine variables that have a high level of risk. From the results of data analysis, 4 variables fall into the high-risk category, namely the problem of land acquisition, work location is not ready, work drawings are not ready, and the core staff of the project is less competent. The results of expert recommendations for the four variables can be stated in preventive and corrective actions.

Benoa-Bandara-Nusa Dua toll road project is the first toll road project in Bali. This highway connects region Nusa Dua with Benoa Harbour area. Construction of toll roads-Benoa-Bandara-Nusa Dua is claimed as the fastest highway development in Indonesia as completed within 14 months. With time so short that the implementation of development it is necessary to research on the risks that arise in the implementation phase of the construction of the toll road The existence of the risks that arise in the implementation of toll road construction will directly impact the cost and development time. It is necessary in order to study the risks that might occur notably members of the dominant risk category can be used as a basis for decision making by the parties concerned to overcome the negative consequences that occur in the construction of toll roads. The research was conducted by means of interviews with various parties and has expert competence in the implementation of toll road construction to determine how the possibility (likelihood) against a variety of risks and to determine how much influences (Consequences) risk. The number of risks identified in this study was as many as 54 risks. The distribution of revenue risk of the project is a total of 18 (33.33%) classified as unacceptable risk, 25 (46.29%) classified as undesirable risk, 9 (16.67%) classified as acceptable risk, 2 (3.7%) classified as negligible risk. Handling risk (risk mitigation) is only performed on the dominant risks are risks that are categorized as unacceptable and undesirable. Risk mitigation conducted on a total of 18 risk unacceptable risk. 25 risk mitigation undesirable risk. Based on the results of this mitigation is then performed risk management ownership (ownership of risk) to the parties involved in the implementation of toll road construction project.

Tambora sub-district is a sub-district that has the smallest area in West Jakarta with the largest population, causing Tambora sub-district to be a densely populated area. Population density which is not matched by the carrying capacity of the environment causes a region to become slum and prone to fire disasters. This study aims to analyze the level of risk of fire disasters in Tambora Subdistrict, West Jakarta. The methodology used in this study were the Multi Criteria Evaluation (MCE) analysis and fire disaster risk analysis by considering the relationship between the hazard and vulnerability variables. The results of the fire disaster risk analysis showed that the most dominant level of fire risk was a moderate risk level of 65.7%, a high risk level of 27.8% and the smallest was a low risk level of 6.5%. Viewed from the size of the area included in the medium and high risk of fire, indicating that Tambora Subdistrict is a subdistrict prone to fire and has a large potential loss of both property and life.

This paper explores the extent of change in acquired immunodeficiency syndrome (AIDS) risk level and in the numbers of AIDS-related risk behaviors in 602 inner-city adolescents as they enter young adulthood. Youths' risk level for human immunodeficiency virus (HIV) infection during adolescence was categorized as high (engaging in prostitution, male homosexual or bisexual activity, or injectable drug use or having ulcerative sexually transmitted diseases), moderate (having six or more sex partners in a 1-year period or nonulcerative sexually transmitted diseases), or low (none of the above). Although a proportion at high or moderate risk during adolescence did move to lower risk levels by young adulthood, the overall risk level stayed fairly stable: 45% were at high or moderate risk levels during adolescence, and 35% were at those levels by young adulthood. Then change in the total number of risk behaviors engaged in by the youths was examined. Knowledge about AIDS or HIV infection and its prevention was not associated with any change in risk behavior, nor were the number of sources of information about the epidemic, acquaintance with those who are infected, estimates of personal risk, or exposure to HIV-test counseling. In fact, youths whose risk behaviors increased the most were more likely to know someone who had died of AIDS and to estimate their own risk as high. Most youths reported that they did not use condoms regularly, disliked them, and had little confidence in their protective ability. Changes in preventive strategies and further research on the causes of behavior change are needed.

Sukasada Sub-District is a region that is largely a hilly area with steep slopes, rainfall intensity is high enough and unstable ground conditions. This leads that the Sub-District of Sukasada becomes potential for the occurrence of landslides. Mitigation effort is therefore necessary to reduce the risk of landslides that may occur. The purpose of this study was to determine the level of threats, vulnerabilities and capacities of level landslides in Sub-District of Sukasada. In addition to the above objectives, the study also aims to formulate strategies for disaster risk reduction of landslides in the Sub-District of Sukasada. The results showed the threat of landslides in the Sub-District of Sukasada is covering 11.169 hectares or 69,51% of the total area. High threat level area is around 727 hectares, the threat level is covering 7.717 hectares and a low threat level area is around 2.725 hectares. The level of vulnerability of landslides in Sub- District of Sukasada ranges from moderate to high. The highest vulnerability level (0.83) is located in some villages, such as: Pancasari, Pegayaman, Panji and Panji Anom Village. While the lowest level of vulnerability (0.66) is in Padangbulia Village. The level of local capacity to landslides in the Sub-District of Sukasada is low, with the resistance area index of 40,25 or capacity level of 0,2349. The level of risk of landslides in the Sub-District of Sukasada is classified as moderate to high. Areas with moderate risk levels are covering 2.032 hectares and a high level of risk covering 7.171 hectares. Strategies that can be done to cope with disaster risk are to reduce the threat, reduce vulnerability and increase capacity. Areas with moderate risk level can be done non-structural mitigation. Structural mitigation can be done in areas with a high level of risk.

Abstract Objective: Cholesterol is one of the cardiovascular risk factors, but also a core component of the central nervous system. Moreover, hyper-cholesterolemia and hypocholesterolemia are directly related to numerous mental illnesses too. This study intents to examine the association between cholesterol level and autolytic behavior among female psychiatric patients. Methods: The present study involves 123 female subjects, who suffered from suicidal thoughts at the moment of hospitalization. The risk of suicidal intentions was assessed by the Modified Scale for Suicide Ideation (Miller et al) and their total serum cholesterol levels were measured. We performed a case-control, analytical, randomized, observational study at the Clinical Hospital of Neurology and Psychiatry Brasov among adult female psychiatric patients admitted during 2014. Results: By our results we distinguished 3 categories: 38 patients with low suicide risk, 32 with moderate risk and 53 with high suicide risk. Significant difference can be noticed in the higher suicide risk patients’ blood cholesterol levels: 44 patients having under 4,5mmol/L total cholesterol level (83%). Although, in other two categories, this proportion is minimal: in the moderate-risk category were 8 patients, representing just 25 %, and in the low-risk category only 1 patient had her cholesterol level under 4,5mmol/L (2,6%). Conclusions: According to our results, proposing cholesterol-level as a biomarker for the determination of high-risk suicide behavior can be important. The presence of other important risk factors (sociodemographic and psychiatric variables) can increase exponentially the suicide behavior. The limitations of this study are the relatively small number of cases and the lack of longitudinal subsequent follow-up. Further investigations are needed on a larger and more heterogenous sample of patients in order to clarify this suggestive correlation.
