Waste is the residual product from an industrial process and the household, useless, no economic value and is a serious problem in the industrial era 4.0, where regulations on environmentally friendly industrialization are an important issue. Primary industries such as sugar cane, oil palm, cocoa produce a lot of wastes during the pre-harvest period such as leaves and three litters, and in the post-harvest period such as pulp, fruit skins, and fruit pulp. PT Berau Cocoa processes cocoa skin waste into animal feed which is applied to cattle in Binungan. This research uses a descriptive research method and how to teach data by distributing 50 questionnaires to cocoa farmers. The results of data analysis show the fact that most cocoa farmers are male of 38 peoples (76%), high school education level of 33 peoples (82%), joined along 4-6 years as 45 peoples (90 %), all respondents are married, and own private land. Supporting factors that influence the processing of cocoa waste into animal feed can be seen from the average value of each factor, method factor (0.596), material factor (0.512), human factor (0.416), and money factors (0.404), and the lowest average is the engine factor (0.312).

Based on the concept of a livable and global age-friendly city, pavements are a public facility that the city should provide to the people. Appropriate pavements will be beneficial for the people, particularly for good quality of life for the elderly to move around in the city. This study explored the behaviour of the elderly in the use of pavements and the problems confronted. The study also evaluated the value of the pavement walking area as it reflected the benefits of pavements to the elderly by applying the Contingent Valuation Method (CVM). During March-May 2017, data were collected using interviews with 601 elderly living in Bangkok. The study indicated that the main problem for senior citizens regarding their use of pavements was from being disturbed by motorbikes riding on the pavements. The average value of pavement for the elderly was about THB 160 (USD 5.30) per person per year. Thus, the benefits of pavements to the elderly in Bangkok was approximately THB 158 million (USD 5.2 million) per year. Thus, policy makers should make proper budget allocations for elderly-friendly pavement management and seriously address the problems confronting the elderly in using pavements, to maximize the usefulness of pavements not only for the elderly but also for the public and to support a sustainable urban development.

Ceramic Tile Production

Ceramic tile production is an industrial process where energy efficiency management is crucial, given the high amount of energy (electrical and thermal) required by the production cycle. This study presents the preliminary results of a research project aimed at defining the benefits of using combined heat and power (CHP) systems in the ceramic sector. Data collected from ten CHP installations allowed us to outline the average characteristics of prime movers, and to quantify the contribution of CHP thermal energy supporting the dryer process. The electric size of the installed CHP units resulted in being between 3.4 MW and 4.9 MW, with an average value of 4 MW. Data revealed that when the goal is to maximize the generation of electricity for self-consumption, internal combustion engines are the preferred choice due to higher conversion efficiency. In contrast, gas turbines allowed us to minimize the consumption of natural gas input to the spray dryer. Indeed, the fraction of the dryer thermal demand (between 600–950 kcal/kgH2O), covered by CHP discharged heat, is strictly dependent on the type of prime mover installed: lower values, in the range of 30–45%, are characteristic of combustion engines, whereas the use of gas turbines can contribute up to 77% of the process’s total consumption.

Tegalharjo village is a village in Glenmore sub-district, Banyuwangi district, which has a very large plantation area with a variety of plants. One of the plants that thrives on plantations and people's homes is the cassava tree. But the use of cassava as a village's potential to improve the economy of citizens is less than optimal. Cassava is generally left to rot in the trees, sometimes sold cheaply with a maximum price of Rp 3.000.00 a kilo gram and even ironically it is only used as animal feed. Meanwhile the majority of housewives only depend on the family economy for their husbands' work as farmers, farm laborers, very few who are self-employed and plantation labour majority. Seeing this, there needs to be innovations that can increase the economic value of cassava. One of them by processing cassava into brownies. After being processed into brownies, the selling value automatically increases from a kilo of Rp 3.000,00 to Rp 10,000.00 in a package. This innovation was carried out by the service team through mentoring activities and training in making Brownies of Cassava.

Gnetum africanum Welw. is a plant specie of Central and West Africa, a Non Timber Forest Product (NTFP) with high nutritional, medicinal and economic value. In Cameroon, its leaves are recognized by the forestry administration as a special product. Strong demand combined with destructive harvesting techniques has resulted in its rarity in its distribution area. The objective of this work is to characterize the harvesting and trade of G. africanaum, and to assess its abundance (density and structure) in order to appreciate the economic value of the Lehman agroforest system (ALM) based in Massoumboum, a village located at 30 Km of Douala town, the economical capital of Cameroon. An ethnobotanical survey was conducted among harvesters and sellers of G. africanum in the ALM and in adjacent markets. An inventory of G. africanum stems and leaves was carried out at an overall sampling rate of 9.52%. The study revealed that, harvesting of G. africanum is freely done by women, youngers and elders. They start their activity early in the morning and convey their products to markets located in the periphery and inside the city of Douala. The price of the gramme is too high in the periphery than in the city, averaging 0.58 CFA franc. This price is high in the dry season due to the scarcity of other agricultural vegetables. The inventories conducted revealed densities of 6 191 stems/ha and 119&nbsp;548 leaves/ha, with the high density of leaves obtained in less perturbed plots. The combination of field data (forest inventories) with those obtained in the markets (trade data), what we call &laquo;&nbsp;quantitative ethnobotany&nbsp;&raquo;, allowed us to appreciate the temporal economic value (EV) of the ALM. This EV ranges from 500&nbsp;000 - 700&nbsp;000 CFA franc, for an average value of 37 059.9 CFA franc /ha. If well managed, G. africanum can contribute not only to the economy of the women-harvesters, but also to the economy of the ALM. The glaring development challenge of the background of what precedes is the development of non-detriment findings (NDF) for G. africanum in Cameroon. These consist of setting tools which aims to sustain the resource and trade such as the delimitation of Gnetum Allocation Units (GAU), as well as the development and implementation of simple management plans (SMPs).

The grooved carpet shell clam (Ruditapes decussatus) is one of the most economically essential mollusks in Mediterranean lagoons and sandy beaches, with fisheries and aquaculture both contributing to its abundance. The goal of this research is to see how varying amounts of acidity affect this calcifying organism. 420 ppm (ambient control), 550 ppm, 750 ppm, and 1050 ppm were used to incubate juvenile clams in CO2  enriched saltwater. With increasing pCO2 , the biological parameters evaluated revealed a small decline. Differences, however, were not substantial. In terms of overall weight, the reduction was greatest at 550 and 1050 ppm. Furthermore, clams kept at 550 parts per million had the lowest condition index and the greatest mortality rate of 8%. Both the 550 ppm and the control 420 ppm groups demonstrated an increase in metabolic rate and ammonia excretion in the physiological response testing. With increasing acidification, the algal feed clearance rate declined, with the highest average value in the control (420 ppm) group and the lowest average value in the extremely high pCO2 (1050 ppm) group. Ocean acidification may put further strain on R. decussatus' health and economic value by the end of the century

Organic Waste Treatment

Organic waste is the largest composition of waste generated by the people of Indonesia, which is around 50-60%. This type of waste, especially food waste, is easy to smell if it is stored for too long so that it has the potential to pollute the environment. On the other hand, organic waste has good nutrients that can be generated, including through BSF (Black Soldier Fly) maggot bioconversion treatment. The BSF maggot bioconversion method is a method of processing organic waste which is carried out by converting organic matter into other products that are useful and have added value by utilizing biological processes from microorganisms and enzymes. Organic waste treatment with this method is generally carried out on a community-based basis and is integrated with the development of agriculture, fisheries and animal husbandry, because maggot cultivation produces commodities of economic value such as compost and maggot larvae. Compost contains very good nutrients so that it can be used for organic farming and maggot contains high protein that can be used for animal feed and fisheries. The implementation of this program was piloted in the boarding school community, namely the Az-Zakaria Islamic Boarding School which is managed by the Az-Zakaria Islamic Education Foundation (YPI) in Sindangbarang Village, Jalaksana District, Kuningan Regency. The result of this implementation is the formation of a new group of entrepreneurs engaged in the cultivation and utilization of BSF maggots.
