An experiment on retail film packaging system was conducted to compare the atmospheric composition within sealed packs containing rambutan fruits. This research was done in order to study the effect of packaging films with different permeability on the some of physicochemical properties of rambutan during storage at 10 °C. The films used were 0.090 mm low density polyethylene (LDPE), 0.040 mm polyprophylene and 0.057 mm LDPE compared unwrapped fruits. Fruits were evaluated every 5 days for changes in moisture content, total sugars, vitamin C, hardness and color. Unwrapped rambutan had severe browning after 10 days. Sealed packages especially the LDPE had delayed the development of the browning for 20 days of storage and had the lowest weight loss.

Mining crimes on the development of environmental law issues in Indonesia are not only carried out by individuals but also by corporations. The violations committed by mining corporations are a violation of criminal law. Company management related must be responsible for the violations that occurred. Thus, the principle of ultimum remedium is very important for the enforcement of criminal law in environmental issues. The main problems in this research study are how the corporation's responsibility towards environmental criminal law violations and the application of the principle of ultimum remedium in the enforcement of environmental criminal law. The research method used was normative juridical and descriptive-analytical. The results of the study show that the applications of the principle of ultimum remedium in mining criminal law are not implemented following the applicable laws and regulations. The law No. 4 of 2009 regarding Minerals and Coal states that the environmental law enforcement violations must be settled through administrative law first, before being settled in criminal law as an embodiment of the ultimum remedium principle.

The concept of sustainable development comes from the environmental sectors. It covered by sustainable development include the agricultural and fishery sector. The sustainable fishery is a collection of activities that provide long-term production sustainability, maintain the balance of ecosystems through generations, and preserve biological, social, and economic systems. However, irresponsible fishing activities such as illegal fishing greatly disrupt the development of sustainable fishery. Besides that, Indonesia has vast amount of potential agricultural land, specifically 100.7 million hectares consisting of 24.5 million hectares suitable for wetlands (rice fields). Having a tropical climate, it is possible to conduct agricultural activities throughout the year. This study aims at analysing illegal fishing as threat to sustainable fishery development and observing land usage systems in integrated agricultural activities. This research utilizes a legal method with a normative juridical approach. Data was collected through a literature review and analysed qualitatively. The results suggest three elements in implementing sustainable agricultural and fishery development, namely economic, ecological, and social elements. Illegal fishing and sustainable agricultural development both affect the attainment of these elements. As a recommendation, implementing sustainable fisheries and agriculture management system which includes efforts to minimize illegal fishing and increase world food barns are very necessary.

Environmental law is a juridical instrument for environmental management which basically includes structuring and enforcement consisting of administrative law, civil law and criminal law. Environmental law enforcement is considered a tool (an end) which functions as a statutory regulation regulating waste quality standards. In Law Number 23 of 1997 concerning Environmental Management, there are several differences with the UUPPLH Number 32 of 2009, which is the application of the subsidiarity principle of criminal law in Environmental Law Enforcement. The application of the subsidiarity principle in environmental law enforcement according to this study is not measurable, subjective and has no legal certainty. There is a debate in the settlement of environmental disputes that must be analyzed, namely whether the application of criminal law is an ultimum remidium (last resort) or a premium remidium (the main effort). The type of research is normative legal research that uses qualitative juridical analysis techniques with literature study and document observation. So from the research results it can be concluded that in formal criminal acts, the role of administrative law must be prioritized in solving environmental problems, after these efforts are ineffective, then criminal law is optimized as a last resort. This is clarified by the UUPPLH on point 6, which states that the function of criminal law against formal environmental law offenses is ultimum remedium because criminal law is a complement to administrative law and civil law. However, for serious crimes and causing public unrest, environmental criminal law is not an ultimum remedium but a premium remedium.
