ABSTRAKWabah pandemi Covid 19 yang dimulai sejak tahun 2020 tentunya menbawa banyak dampak baik daeri segi kesehatan, sosial, dan tentunya ekonomi. Dampak tersebut dirasakan oleh semua kalangan baik dari pengusaha besar sampai pada level rumah tangga. Konsumsi rumah tangga, sebagai penopang utama perekonomian masyarakat melambat secara signifikan, dimana pada akhirnya memengaruhi kinerja industri dan Usaha Mikro, Kecil, dan Menengah. Usaha mikro sebagian besar di jalankan oleh ibu – ibu rumah tangga yang memiliki kesempatan dan waktu. Di beberapa daerah yang memiliki potensi sumber daya, keberadaan UMKM menjadi hal yang sangat membantu perekonomian rumah tangga. Namun di beberapa daerah, ada pula masyarakat yang masih kesulitan dalam memulai berwirausaha. Hal ini dikarenakan kurangnya pengetahuan, pengalaman, dan motivasi. Oleh karena itu, tujuan dari kegiatan pengabdian masyarakat ini ialah melaksanakan pelatihan kewirausahaan. Berdasarkan keinginan untuk memberikan manfaat yang lebih besar bagi ibu rumah tangga di Kelurahan Karang Joang tepatnya di RT 30, maka dengan segenap pengalaman, pengetahuan, dan berbagai hasil survei serta konsultasi, maka pengabdian ini direncanakan yaitu berupa pelatihan pembuatan produk makanan dan minuman serta produk sampah daur ulang serta edukasi berwirausaha. Kata kunci: wirausaha; ibu rumah tangga; pandemi covid 19. ABSTRACTThe COVID-19 pandemic, which began in 2020, has certainly brought many impacts, both in terms of health, social, and of course the economy. This impact is felt by all groups, from big entrepreneurs to the household level. Household consumption, as the main pillar of the community's economy, slowed significantly, which in turn affected the performance of industry and Micro, Small and Medium Enterprises. Most of the micro-enterprises are run by housewives who have the opportunity and time. In some areas that have potential resources, the existence of MSMEs is very helpful for the household economy. However, in some areas, there are also people who still have difficulty starting entrepreneurship. This is due to a lack of knowledge, experience, and motivation. Therefore, the purpose of this community service activity is to carry out entrepreneurship training. Based on the desire to provide greater benefits for housewives in Karang Joang Village, precisely in RT 30, then with all the experience, knowledge, and various survey results and consultations, this service is planned in the form of training in the manufacture of food and beverage products and waste product recycling and entrepreneurship education. Keywords: entrepreneur; housewife; covid 19 pandemic.

Coastal areas are often in the spotlight related to environmental problems, such as plastic waste. Coastal and coastal areas often face complex problems related to plastic waste, including microplastics. Microplastics (MPs) are tiny pieces of plastic that are as small as ≤ 5 mm and possibly pollute the environment. The study aimed to identify the presence and abundance of microplastics contaminating the coastal areas of Balikpapan City. Sediment samples were taken at a depth 0-10 cm. The observations were carried out in several stages; those stages are the drying stage, volume reduction, density separation, and counting using a microscope. The microplastic observation results with the microscope showed four types: fragment-shaped microplastics, phylum-shaped microplastics, fiber microplastics, and microbead-shaped microplastics. The highest number of microplastic particles was found at the Kampung Atas Air point, about 201 particles / 100 grams of dry sediment and the least number of microplastic particles were found at the Monpera point, about 16 particles / 100 grams of dry sediment. Microplastics with fiber form dominated all the study areas. Environmental conditions and pollutant sources influence the difference in the number of microplastics

Laundry wastewater contains not only detergent but also contains fabric fibres and threads. Microplastic fibres have been discovered as a potential source of microplastic fibres in synthetic clothing washed in the environment. To reduce microplastic concentration in wastewater, many approaches have been developed. Electrocoagulation is one of them. Using both synthetic microplastics and laundry wastewater samples, this study examined the performance of electrocoagulation methods to remove microplastics. The flocculation and deposition mechanisms remove microplastic fibre. This research was set up by using a reactor with a volume of 1 L, 60 V of voltage and 60 minutes of contact time. Electrical current of 5A and 10A was applied to remove microplastic fibres during electrocoagulation (EC). The removal efficiency of polyester fibre was 55-68 per cent for 60 minutes with a current of 5A and 42-85 per cent for 60 minutes with a current of 10A. Polyamide fibre removal efficiency in 60 minutes is 53 per cent to 74 per cent at 5A current and 57 per cent to 72 per cent at 10A current. According to this study, it can be concluded that EC can remove microplastic fibre from laundry effluent.

Balikpapan bay has an important and strategic role, such as a buffer for sustainability of the estuary function as the Balikpapan seaport. In Balikpapan esuary watershed there are large and small rivers, including Somber River. Settlements and industries around the river banks have caused a decrease of river water quality, especially activities that place pollutant loads (waste) on the river bodies. This research is focused on physical and chemical parameters, including Total Dissolved Solid (TDS), temperature, pH, and DO (Dissolved Oxygen).Water quality research was conducted by dividing the river into 7 measurment points. The distribution of measurement points was based on water quality considerations that represent upstream, middle, and downstream water quality, as well as considering easy access. Water samples at each mesurment point ware collected at three different depths (vertically). Concentrations of several parameters that have been obtained were then analyzed using the Pollution Index method (Pollution Index) which is used to determine relative pollutant levels to the allowed water quality parameters. The testing procedure by pollution index refers to procedure poured in the Decree of the State Minister for the Environment No. 115 in 2003 concerning of Determining Guidelines of Water Quality Status. Based on the field measurments, an average value for temperatures obtained ranging from 30.0 - 32.1 ° C, TDS values 4270 mg / L - 10000 mg / L, DO ranges between 1.8 mg / L - 3.1 mg / L, and pH values between 6.6 - 7.1. From the calculation and data analisys of physical and chemical parameters, the research can be concluded that the location of measurement point 1 shows water quality status being lightly polluted, while point 2,3,4,5,6, and 7 shows water quality status being moderately polluted. Keywords: Water quality, estuary, Somber river, pollution index
