/0 Comments/in /by

The dragon fruit peels (Hylocereus undatus) are typically thrown away as agricultural waste. The disposal of bio-wastes, like peels from dragon fruit and microbiological contamination during their mass breakdown, all contribute to environmental degradation. Peel can be used to extract naturally occurring colour for pigments. The objective of this study is to investigate the feasibility of using the peel of Hylocereus undatus as a coating material for wound healing. The extraction method and potential uses of the pigments derived from the peel will be explored. The study aimed to determine the phytochemical components of Hylocereus undatus (peel) extract and the peel can be utilized as a raw material for pigment extraction due to the betalain content. With the use of a magnetic stirrer extraction, the peel of Hylocereus undatus was extracted with aqueous extraction. Thin layer chromatographic techniques are used to identify the pigment components. In the present study, we recorded both UV-VIS and FT-IR profile of peel extract to known the various phytoconstituents and determine the functional group present in Hylocereus undatus (white dragon fruit). The pigment needs to be applied to the wound gauze, and the stain resistance should be evaluated by determining how well the wound gauze can withstand contamination from the outside coating. Furthermore, the pharmaceutical and nutraceutical sectors are interested in Hylocereus undatus peel due to its components, which may have potential health applications such as anti-inflammatory, antioxidant, antibacterial, and anti-cancer characteristics

/0 Comments/in /by

As a huge maritime country, Indonesia has tremendous potential for marine resources. Indonesia is the largest tropical marine country in the world and has the largest biodiversity in the sea. The potential of marine biological resources in Indonesian waters has always been able to provide optimal benefits for the economic and socio-cultural development of the community. However, many fishermen conduct fishing easily and destructively (destructively fishing) of marine ecosystems using fishing gear that is not environmentally friendly to meet the demand for fish needs.  The perpetrators use Dupont Lannate chemicals containing Methomil with mashed fish and then spread it into the sea, then pick up the dead fish.  The use of chemical poisons can kill the animals that make up the coral so that the coral becomes discolored which eventually dies and other fish that are not targeted also die. Therefore in this study, the author examines law enforcement in Indonesia’s marine territory to protect the biodiversity of Indonesia’s marine areas. this study uses a Normative research type that examines national and international legal arrangements regarding the protection of the marine environment. Therefore researchers examine the regulation and effectiveness of law enforcement in Indonesia.

/0 Comments/in /by

Despite of Indonesia’s vast solar energy potential according to the Indonesian Ministry of Energy and Mineral Resources, Indonesia’s total installed capacity of rooftop solar photovoltaic (PV) is very far from Indonesia’s target of 3.6 GW in 2025. Indonesia once applied net metering scheme for rooftop solar PV policy and was expected to be able to boost rooftop solar PV growth. A system dynamics approach is used in the research to develop an assessment model to evaluate the policies’ impact on residential rooftop solar PV system growth. A Causal Loop Diagram was established then transformed into Stock and Flow Diagram (SFD) using software Vensim PLE 10.1.3, which was used to simulate several policies’ scenarios related to residential rooftop solar PV adoption and CO2 emissions reduction. Ten scenarios were simulated in this study involving three groups of intervention: initial net metering tariff, reduction on initial solar PV cost, upper limit of ROI, and combination of initial net metering tariff and initial solar PV cost reduction. The simulations revealed that combination of increasing net metering tariff to 80% & initial cost reduction 30% has the highest potential solar PV installations, the highest CO2 emissions reduction, and the lowest accumulation cost of net metering in 2030. This study can be used as reference by the policy makers in Indonesia to formulate the optimum policy to boost rooftop solar PV growth as the simulations shows that residential rooftop solar PV with the right intervention can meet the government’s target of rooftop solar PV in 2030.
