The leather tanning industry or tannery, mainly in the small and medium scale (SMEs), is not environmentally friendly. Limited capitals drive the SMEs-scale tanneries to dispose of liquid waste directly into water bodies without proper treatment.  It might cause serious environmental problems due to the high content of COD, BOD, chromium, and dyes.  Treatment of liquid waste using constructed wetlands has been widely used because it is efficient, cheap, and powerful. This review discusses the latest studies in the wastewater treatment of tanneries using phytoremediation techniques and constructed wetlands and their potential applications in the SMEs tanneries.

Diarrhea is the excretion of faeces with an increasing frequency (three times a day) with a change in the consistency of the stool to become soft or watery, with or without blood / mucus in the stool. in 2019, there were 4,485,513 cases of diarrhea in Indonesia with diarrhea services for children under five by 40%. The purpose of this study was to provide information about risk factors for the incidence of diarrhea in children under five based on review studies. This research method is a literature review using the Sinta database as a reference. Categorization is done, index 2-4, publications in the last 10 years, and has variables related to risk factors for the incidence of diarrhea in children under five. The results of this study were found that environmental factors such as clean water facilities, latrine facilities, household waste management, liquid waste management, maternal knowledge, and personal hygiene are risk factors that cause diarrhea in toddlers. The conclusion of this research is that there are factors of poor sanitation, maternal knowledge, and personal hygiene which are risk factors for the incidence of diarrhea in toddlers that must be corrected.

Arya Jaya is a trading business that is engaged in making tofu. UD. Arya Jaya began operations in 2003, by Mrs. Siti Aisyah. UD. Arya Jaya is in Bukkolan Village RT.01 RW.01 Paowan Village / Panarukan District Situbondo Regency East Java Province. To run this business, Mrs. Siti Aisyah was assisted by 12 workers.         At UD. Arya Jaya, so far the tofu wastewater has never been used and treated but has been discharged into the river. As a result, various cases of environmental pollution that make a negative impact on public health occur a lot.         Community service activities are also intended to train and foster communities around the tofu industry and tofu entrepreneurs so that they have knowledge about the utilization of tofu liquid waste and can improve skills around 75% to process tofu liquid waste into biogas in processing tofu liquid waste into biogas so it is expected With good management of the waste produced by the tofu making industry, it will add value to the product and be more environmentally friendly. In addition, the management of tofu wastewater in a waste to product manner can efficiently cost the costs, materials used, and energy to make new products from waste raw materials. Besides that, entrepreneurs know that they will no longer be difficult to deal with their waste.         Based on the situation analysis above, the PKM Team together with UD. Arya Jaya seeks to overcome the problem referred to as "The Socialization of Tofu Liquid Waste Management (Whey Tofu) Becoming Biogas As an Alternative Energy Reserve in the Framework of Creating an Environmentally Friendly Industry". The activity that will be carried out has very good prospects and is expected to provide information about the processing of tofu industrial wastewater using anaerobic biodigester technology for biogas production. For tofu industry entrepreneurs, the processing of various wastes can be converted into biogas into added value. By paying attention to environmental problems caused by the disposal of potentially polluting waste, the existence of anaerobic biodigester technology can provide economic and ecological value while reducing the potential for disposal. In addition, it can reduce the effects of pollution resulting in the greenhouse effect.         The final target and output are the publication of scientific articles in journals or proceedings in national community service seminars and newspaper article publications in national newspapers.

Assessment of Management of Liquid Waste and Solid Waste useful to prot>ide a11 Ol'erview for stakeholders in making decision to develop a waste management system of output from ai1port operation which sustainable and environmentally friendly. T71e assessme11t took a case study at Ngurah Rai Airport which is the second largest airport in Indonesia. T7re assessment looks at the waste management procedures, both liquid and solid waste at tlie airport. In addition, this study provides arz overview of relationship between the number of passengers, the number of aircraft and the production of solid waste. Given this assessment can be seen that the waste management system has been implemented and can provide recommendations related to the waste management system to other airports.

Chitosan has been used as biosorbent. In addition to having advantages, chitosan as biosorbent also has disadvantages. Chitosan is very soluble in low pH, so it cannot adsorb Cr (total) at low pH. It is because the active site (amine group) of chitosan undergoes protonation, and its adsorption capability is easily influenced by anions in waters. Therefore, this research studied the use of chitosan coating on active charcoal of coconut shell to increase the adsorption capability of Cr (total), BOD, and COD. This research was done to evaluate the characteristics of the liquid waste quality with or without Wastewater treatment unit (IPAL), and compare them with the Regulation of DIY Governor number 7/2010. It also studied the effect of pH and Concentration of chitosan coating on active charcoal as adsorbent on the decrease of Cr (total), BOD, and COD concentration in the liquid waste of leather tanning. The results indicate that the liquid waste of the leather tanning industry with and without Wastewater treatment unit (IPAL) have exceeded the quality standard for the liquid waste of leather tanning industry. An ANOVA statistical test indicated that Cr (total), BOD, and COD are significant at 0.05 (p < 0.05), with various pH influencing the decrease in Cr (total), BOD, and COD. The highest removal percentage resulting from the effect of chitosan concentration coating on active charcoal is obtained in adsorbent C (K3A1), with Cr (total) (91.9%); BOD (99.5%); and COD (98.47%).;

Influent and effluent data from about 120 small wastewater treatment plants (100 - 2000 PE) have been collected and processed. Seven different types of plants are represented. The effluent quality and the treatment efficiency have been evaluated. The most common type of plant is mechanical/biological treatment plants. Some of them are nitrifying and some are also extended for chemical precipitation of phosphorus. Constructed wetlands and biological sandfilters are also represented among the small wastewater treatment plants.

Histopathological Results

Most reported cases of middle ear adenoma (MEA) have focused on histopathology because MEA is usually diagnosed postoperatively, which is considered as a major setback. We focused on the surgical aspect of the disease to facilitate a preoperative diagnosis, resulting in prompt and proper treatment, without requiring a second stage of surgical treatment. In this report, we present the differential diagnoses in a 40-year-old man with MEA requiring surgical treatment. Preoperatively, the patient was suspected to have an MEA. An analysis of the surgical procedures in similar misdiagnosed tumors has enabled us to assess surgical procedures in cases wherein the preoperative diagnosis does not coincide with the postoperative histopathological results.
