Abstract

Research aimed to learn and know the bottom intrusion mechanism in Hurun Bay Lampung. Three kinds surveys were conducted consist of mooring survey, synoptic oceanographic survey and 25 hour survey. The monitoring data of water temperature indicated that at Hurun Bay occurred bottom intrusion from middle February until early July. The mass water was colder, more saline and contained less DO than the overlaying water. These phenomena may be caused by eastern monsoon from Java Sea to Lampung Bay and Hurun Bay. Vertical profile distribution showed that there are significant different in temperature, salinity and DO between surface and bottom layer. Along bottom deeper than 22m were identified as a termocline layer which was colder and more saline and contained less DO. Result of 25 hour survey resumed that the lowest DO in this water mass appeared in early July and it propagated from offshore to the coast with velocity 0.07 m/s. This condition will be a treatment for marine cultivation stakeholder in this area.Key words : Bottom Intrusion, Hypoxia

Abstract

Global warming has become an increasingly important issue around the world today due to the rise of anthropogenic greenhouse gases emission, which gives several negative impacts on human life. There are some techniques have been studied and assessed i.e. physical mechanism by injected CO2 to the geological formations, chemical mechanism with artificial tree technology and biological mechanism by increasing the primary production through iron enrichment in high nutrient-low chlorophyll (HNLC) waters as well as mixing of water column below the sea surface. Those technologies, which are well known as Carbon Capture Storage ‘(CCS) technology, are expected to be applied to reduce the oncentration of anthropogenic CO2 in the atmosphere and to minimize the global warming. The Center of Environmental Technology, Agency for the Assessment and Application of Technology (BPPT) will carry out a research concerning CO2 reduction by a phytoplankton culture in a photobioreactor in three years. The main objective of this research is to assess the CO2 uptake capability of tropical phytoplankton. In this paper, we would showed the creteria and design to assembly a photobioreactor esspesially a air lift photobioreactor. To improve performance photobioreaktor, the materials included design criteria and the dynamics of fluids in fotobioreaktor have to considered propoerly. Other the hand, the selection of the most productive species and selection of appropriate media and economically also important to be done. Keywords: global warming, creteria and design, greenhouse gas, air lift photobioreactor

Abstract

Indonesia’s rich supplies of corals and reef fish are endangered by destructive fishing practices. Cyanide and blast fishing are widespread throughout the archipelago even in protected areas. Indonesian reefs are also subject to various pressures from inland activities. Forestation and other land-use changes have increasedsediment discharge onto reefs, and pollution from industrial effluents, sewage, and fertilizer compounds the problem. Cumulatively, these pressures appear to have significantly degraded Indonesia’s reefs over time. Unfortunately, Indonesia has only limited monitoring. Few reefs are regularly studied, making the assessment of condition and change for the country quite difficult. Currently, most monitoringmindicates clearly that reef condition is declining. This article showed the status, biology, and monitoring-rehabilitation method of coral reef in Indonesia.

Abstract

ABSTRACTThe government efforts to maintain national energy stability program through the increase energy supply and saving must be supported by all levels of society. Several energy observers and experts stated that the contribution of the domestic or household sector in the activities of energy saving program is quite significant because the percentage of household customers are relatively high. This paper analyzes the potential of providing research data on the percentage of electricity savings in the domestic or household sectors towards saving electricity nationally. The results of the study show that electrical devices commonly used in households still have the potential to be saved. Electrical devices that are often used at households and have great saving potentials are air conditioners and refrigerators. If each household customer saves 30% of electricity consumption, then the national electricity supply that can be saved will be around 5,679 GW, equivalent to 83.3 trillion rupiah. The saving program resulted in savings of electricity consumption of around 6% of all household consumers or around 2.9% of total national electricity consumption.Keywords: electrical energy, savings, households ABSTRAKUpaya pemerintah dalam menjaga kestabilan energi nasional melalui program peningkatan pasokan dan penghematan energi harus didukung oleh seluruh lapisan masyarakat.
