It has been over 72 years since Indonesia proclaimed her independence on 17 August 1945. However, the 350 years of the Dutch colonization is still impacting the lives of the Indonesian people. The difficulties faced by the Indonesian legal system as the government tries to accommodate adat (custom) and religion principles within the national law and the extent to which this legal mechanism affects the everyday life of the Indonesian people. In a nation where customs and religion are so preeminent, setting up an all-inclusive document meant to be the foundation of the state’s legal system at the dawn of independence was no easy task. This paper discusses the practice of legal pluralism in Indonesia and its struggle to implement rule of law and human rights principles after a half-century of authoritarian regimes. The study involves socio-legal research drawing on empirical data. Survey research was conducted between September 2014 and February 2015 at Utrecht University, the Netherlands, as well as in 5 cities in Indonesia (Aceh, Bali, Batam, Medan, and Padang) to collect data. The research reveals that legal pluralism is not helping to strengthen the Indonesian legal system, and that the foreignness of the Western law along with the neglect of the Indonesian customary and Islamic laws, totalitarianism and military involvement in politics, corruption within the state apparatus and unsynchronized laws weaken the legal system in Indonesia and hinder its effort to implement rule of law and human rights principles.

This laboratory work was carried out to evaluate the insecticidal activity of the extracts of Piper retrofractum (Piperaceae) fruit and Tephrosia vogelii (Fabaceae) leaf and their mixtures against the cabbage head caterpillar, Crocidolomia pavonana. Ground plant materials of the two plant species were extracted separately with n-hexane and methanol. The results of leaf-residue feeding bioassays showed that P. retrofractum (Pr) and T. vogelii (Tv) hexane extracts had strong insecticidal activity against C. pavonana larvae (LC95 < 0.5%) and were more active than their respective methanol extracts. Pr and Tv hexane extract had a moderate and a rather weak contact effect on C. pavonana larvae, respectively. In feeding tests, Pr + Tv (1:1) hexane and methanol extract mixtures indicated synergistic joint effect both at LC50 and LC95 level, whereas in the contact test, the mixture of Pr + Tv (1:1) hexane extract was synergistic at the LC50 level but antagonistic at the LC95 level. In choice tests, antifeedant effects of Pr and Tv hexane extracts at LC25 to LC70 levels on C. pavonana larvae followed a concentration-dependent fashion. Thus, separate or mixed P. retrofractum and T. vogelii extracts are potential alternatives for the control of C. pavonana.

The existence of sovereign rights in the North Natuna Sea has begun to be disturbed since China's claim of traditional fishing rights was strengthened by the nine-dash line claim. This claim includes the North Natuna Sea area into China's territorial sea, which makes this area a conflict area. The problem in this research is the existence of traditional fishing ground rights in UNCLOS III 1982 and the impact of the nine-dash line claim on Indonesia's sovereign rights in the conflict area of ??the North Natuna Sea. This study uses a normative legal research method with a statutory and conceptual approach. The results of the study explained that the 1982 UNCLOS III did not regulate traditional fishing ground, and the impact of the nine-dash line claim is very significant, as can be seen from the activities of Chinese fishers in the North Natuna Sea, which are supported by Chinese coast guard vessels, which have disrupted Indonesia's enjoyment of its sovereign rights. Thus, it can be concluded that the traditional fishing ground rights with the nine-dash line claim are not based on international law but are only based on China's unilateral claims and create conflicts that impact Indonesia.

In the law enforcement of corruption, there are at least 2 (two) articles that are often used to ensnare the defendant, namely Article 2 paragraph (1) and Article 3 of Law Number 20 Year 2001 regarding the Amendment of Law Number 31 Year 1999 regarding Eradication of Corruption. In practice, the provision has been applied by the Judge in the decision of corruption case in the implementation of partnership program and environment development with the actors from the private sector, as the Manager of Lubuk Alung Regional IV branch PT. Sang Hyang Seri (Persero) is found guilty because it has been proven legally and convincingly committed a criminal act of corruption by misusing and using the.
