Harumanis is type of mango in Indonesia that meets the needs of export or local markets. Harumanis mango have not been able to fully boost the rate of export of this Indonesian fresh fruit due to poor postharvest technology. This condition has an adverse impact as it increases postharvest loss. Thus, in these conditions there must be postharvet handling of harumanis mango, one of which is edible coating made from chitosan with the addition of starch. The difference in the value of amylose and amylopectin from starch resulted in differen results. The aim of this research was to determine the effect of addition of starch types in chitosan edible coating on the postharvest loss of harumanis mango based onthe physico-chemical tests. The experiment used completely randomized design with two factor. The parameters observed were physical test including weight loss, texture, and color. Chemical test including respiration rate, vitamin C, and total soluble solids. The result showed that the addition of starch on chitosan edible coating significantly affected postharvest loss to the results of physical and chemical tests. The best treatment was the addition of starh to edible coating with chitosan because it can provide physical and chemical defense during storage at room temperature.

Tobacco is an important commodity in the economy in Indonesia. Tobacco stems are worthless waste. Tobacco stems contain 56.10% cellulose, making it high potential as a particle board raw material. The process of making particleboard that affects quality is the pressing process during printing. Greater pressure printing presses make bonds between particles stronger. Strong bonding between particles is intended so that the board does not change during storage. The purpose of this study is to determine the characteristics of particleboard in various variations of printing pressure load and storage time and to find out the best treatment as a recommendation in the manufacture of tobacco stem particleboard. The research method was factorial CRD with a combination of treatments between 2 factors namely printing load (4 kg and 8 kg) and storage time (0, 12, and 24 days). The results showed 1.13 - 1.25 g.cm-3 for the density value, water content 4.97 - 12.57%, and water absorption 240.03 - 208.00%. MOE and MOR values were 16000.13 - 36222.77 kgf. cm-2 and 824.47 - 1697.83 kgf.cm-2. The recommended treatment load is 8 kg printing pressure with 12 days of storage time.

Waste management that is not good will also have a negative impact on the environment, public health, and this certainly has wider implications such as environmental pollution. This article outlines environmental governance in the waste management process and a model of good urban waste management. Environmental governance is important in understanding the issue of waste management which is a complex environmental issue in urban areas. A good model for waste management is with the unit paying attention to sewage, leachate water treatment, and combustion of methane / flare gas access. The model described as integrated management is widely applied in big cities. The integrated waste management process is carried out by implementing preventive measures and reuse efforts with the aim that the waste does not form.

This study aims to determine the impact of the Meleura Beach attraction for the economic life of the Lakarinta Coastal community, Lohia District, Muna Regency. This research was conducted using qualitative methods or purposive sampling techniques. The results showed that the local community felt a positive impact on the existence of this beach area, especially those directly involved with the development of Meleura beach tourism objects both economically. The development of Maleura Beach also has an economic impact, in the form of changes or shifts in the livelihoods of most Lakarinta villagers, from farmers to traders and service providers. Changes and/or transitions like this are followed by changes in community income which also shows an increasing trend. If before the beach was developed, the majority of residents who had jobs as farmers were only able to receive between Rp 1,000,000-5,000,000 per year, now on average they are able to receive more than Rp 10,000,000 per year, even some of them can receive more than Rp 100,000,000 per year. The need for solid government funding and community institutions to help improve the economic life of the community and help provide solutions that benefit the community.

The amount of mango production in Indonesia is quite high, but the quality of postharvest mangoes is still quite low. The quality of the fruit will decline due to contamination; one of the contaminants is fungi. The way to reduce the damage of postharvest products is by coating applications. The purpose of this study was to study the physical, chemical and antifungal activities of harumanis mangoes’s quality which had been given coating during storage that could cause postharvest losses of harumanis mangoes. There are 3 treatments, each of them are respectively the provision of corn based coating 6% tobacco extract, 8% tobacco extract and 10% tobacco extract. The physical and chemical properties of the antifungal coating of tobacco extract made from corn coating for post-harvest damage on harumanis mangoes were obtained by weight loss, texture, colour, respiration rate, vitamin C and total dissolved solid. Preventing coating can prevent damage after harvest and protect the harumanis mango; therefore the quality of the mangoes can be maintained. The best results from the priority with the largest diameter inhibition zone were given corn starch 10% tobacco extract. Then the higher the concentration of extract used, the greater the diameter of the inhibition zone obtained. Based on all the tests performed (physical, chemical, and antifungal) the best treatment from the treatment was obtained that consisted of mangoes with antifungal layers of corn starch 10% tobacco extract. Because the P3 obtained the best results in maintaining physical, chemical content and fungi for 15 days.

Lack of fish catch is one of the problems faced by coastal communities. From the fish farming activities in the sea, the community can obtain enormous economic benefits and support the economic growth of the family through the sale of fish from aquaculture. The government has given the opportunity and responsibility to the community in managing its resources, where the community itself has a need, goals, and aspirations and the community also makes decisions for their welfare. Socialization is needed regarding the importance of keeping coral reefs because the benefits are very good for coastal communities. The challenge faced is because coastal communities are increasing the ability and knowledge of the community about the importance of protecting ecosystems and capturing fisheries that are safe for the environment.

The importance of isolating a microbe from the environment, such as food (solid substrate), drinks (liquid substrate), and yourself because of the many microbes that are difficult to observe or distinguish directly using the five senses. A sample can contain bacteria or fungi. By isolating, the shape of the colonies and the contents in a sample can be observed. Bacteria from the air and normal flora form colonies with lobate-shaped edges, whereas bacteria found in well water samples form colonies with irregular edges and there are also fungi found in the well water samples.

Ecological sustainability refers to the maintenance of the environmental order on earth so that its sustainability can be maintained. Three aspects must be considered to maintain the integrity of the environmental order, namely; carrying capacity, assimilative capacity and sustainable use of recoverable resources. Environmental development management is essential for ecosystem sustainability. Macroeconomic sustainability guarantees sustainable economic progress and encourages economic efficiency through structural and national reforms. Food security is defined as a condition for the fulfillment of food for households which is reflected in the availability of sufficient food, both in quantity and quality, safe, equitable, and affordable.
