Abstract

As part of the coastal and marine environment, mangrove ecosystems are often degraded due to more levies/logging, the conversion of nikau forests into ponds shrimp, and pollution.  The decline in the quality of this area originated from anthropogenic factors from land pollution originating from land (land base), as well as pollution from marine activities (seabase). The threat needs to be anticipated through increased awareness and awareness of key stakeholders (logging communities).  In terms of environmental science, this ecosystem is seen as a potential bulwark of carbon and other environmental services.  This activity is an effort to provide understanding to the general public and government officials about the various benefits and importance of mangrove conservation efforts.   Counseling on this topic is very necessary because there is information about community complaints about the high exploitation and threats to the sustainability of its existence in Kampung Rawa Mekar Jaya, Siak Regency.  Counseling is considered important to be carried out because of the increasing degradation of coastal ecosystems (mangroves, coastal waters, estuaries) due to environmental pressures from human activity. From this community service activity, it is hoped that it can increase the knowledge, understanding, and awareness of the local community about the benefits of long Janka to maintaining coastal and marine ecosystems. The mindset of coastal communities is expected to be open and understand what can be done, what can and cannot be done to coastlines and mangrove ecosystems, for the sake of preserving natural resources and the environment related to the lives of the general public and especially fishermen whose lives are largely dependent on these ecosystems. The form of this planned community service activity is counseling on the importance of mangrove forest ecosystem conservation as an effort to preserve the ecology of coastal areas and coastal waters of Kampung Rawa Mekar Jaya, Siak Regency.  Counseling on this topic is considered very necessary considering the increasingly intense community activities that cause overexploitation of mangrove forest areas. This activity is one of the efforts to bring the name of Riau University into contributing to the development of community service specialties, especially education in the field of mangrove forest ecosystem management

Abstract

Hospitals as health service institutions that carry out individual health services in a plenary manner, apart from having a positive impact, they also have a negative impact on the environment and public health by producing medical waste. As a health service provider, hospital managers are obliged to prevent environmental pollution and maintain public health. This can be achieved by carrying out proper and correct medical waste management in accordance with applicable regulations. X Mandau Hospital has implemented medical waste management even though it is not optimal and still has many shortcomings. This study aims to analyze medical waste management at X Mandau Hospital using a regulatory approach and the factors that are considered to influence medical waste management.This type of research is observational research by describing the medical waste management system from the input and process aspects to find out the problems that exist in medical waste management at X Mandau Hospital and to develop a medical waste management strategy based on factors that affect both internal and external use. SWOT analysis. The types of data used are primary data, secondary data and literature studies.     The results of research at X Mandau Hospital show that the stages in medical waste management are still not in accordance with applicable regulations. In the reduction and sorting stage, the storage stage and the processing stage, serious violations were found. With an average medical waste generation of 88.98 kg / day and with the inoperable condition of medical waste treatment equipment, Hospital X is considered to be facing serious medical waste management problems. The main problem found in the input aspect is the absence of good planning in the budgeting process for system development, operation and maintenance, this then has an impact on handling the generation of medical waste. In the process aspect, operational techniques that have not met the applicable regulations have resulted in conflicts with the community which have resulted in the rejection of incinerator operations. On the other hand, the incinerator operation itself has not yet obtained a processing permit from the authorized agency. To deal with this problem, the management strategy that can be taken is to carry out efforts to develop and improve medical waste treatment facilities utilizing government support, availability of human resources, budget, facilities and infrastructure as well as the availability of technology to then take advantage of opportunities for collaboration with other parties in medical waste treatment.

Abstract

Tofu is a traditional food for most people in Indonesia, which is favored by almost all levels of society including those in Riau Province. Besides containing good nutrition, making tofu is also relatively cheap and simple. It tastes good and the price is affordable by all levels of society. At present, the tofu business in Riau Province is on average still carried out with simple technology, so that the efficiency level of resource use (water and raw materials) is felt to be still low and the level of waste production is also relatively high. The purpose of this research is to develop a waste management strategy for the tofu pabarik tofu in Tarai Bangun Village, Tambang District, Kampar Regency. In general, tofu is made by craftsmen or home industries with simple equipment and technology. The process order or method of making tofu in all small tofu industries is generally almost the same and even if there is a difference it is only in the order of work or the type of protein coagulating agent used. This research was conducted in September - November 2010. The research location is a tofu factory in Jalan Sukajadi, Tarai Bangun village, Tambang sub-district, Kampar district. Sampling was done using the AHP questionnaire for the tofu factory waste management strategy. The management of the tofu factory should pay attention to several important things as the researchers recommended. These parameters consist of aspects of ecology, economy, socio-culture, environmental ethics, PP-UU, chemistry and physics. The results obtained based on the distribution of questionnaires can be seen in Figure 5. Based on the seven parameters presented the chemical parameters have the highest value, namely 0.33 and 0.26 physics, while the environmental ethics parameter is 0.17. The hierarchical rankings of the tofu factory business management in this study are, respectively, chemical, physical, UU-PP, environmental ethics, socio-culture, economy and ecology. Even though the ecological parameter is in the last rank in this hierarchy, where ecologically the pollution has not been so severe, it is proven that in the research location it does not cause social conflict with the surrounding community and the ethics used is still on biocentrism.
