The target of community service assignments in 2018 is productive communities that need development in the field of environmental management, namely employees of the Quality Control Laboratory of PT. Semen Baturaja OKU. Coal ash is a waste unlike gas from combustion, because it is a solid material that is not easily dissolved and is not volatile so it will be more troublesome in handling. If the amount is large and is not handled properly, then the coal ash can pollute the environment especially caused by fly ash and can be sucked by humans and animals can also affect the condition of the surrounding water and soil so that it can kill the plants. The chemical composition of Fly ash is silica, alumina and iron with little calcium, magnesium, sulfate, and other components. Currently coal fly ash is used in cement plants as a mixture of concrete makers. Because of the smoothness and round shape of the granules, the use of fly ash on the concrete mixture can increase the slack on the concrete mixture. The advantages of using fly ash include increasing the strength of concrete, filling the pores in the concrete so that the porosity of the concrete becomes low, while increasing the density of concrete so that it can increase the tightness of concrete to water. The coal fly ash waste that accumulates also occurs in the industry of PT Semen Baturaja Ogan Komering Ulu. PT. Semen Baturaja is one of the largest cement industries in Sumatra that produces PCC (Portland Composite Cement). PCC type cement is cement made by utilizing inorganic additives such as fly ash and trass. Aside from being an additional material for cement, fly ash can also be used as a raw material for making silica membranes which serves to reduce metal content in acid mine drainage. So that the author wishes to socialize the employees and employees of PT Semen Baturaja especially in the BTA II Quality Control laboratory division to disseminate knowledge about the benefits of coal fly ash as raw material for silica membranes in minimizing B3 waste so that environmental management with a friendly environment will achieved.

Durian waste is the basic ingredient of making this briquette and just piling up into waste in the neighborhood where it sells and can not provide economic value. Now the material we used to call environmental waste will turn into alternative fuels. Through the process of processing, durian waste will be fuel in the form of briquettes and this product will have a fairly high selling value. The briquettes also smell good when used, making them suitable for the food industry, both large and large scale. Because of these several advantages, durian leather briquettes have wide open market potential in both local, domestic and export markets. The method implemented is to socialize the utilization of durian skin by spreading knowledge with the manufacture and processing of durian skin so as to produce the outcome of durian briquette product as a substitute of fuel in the era of expensive energy.

Energi surya merupakan salah satu sumber energi terbarukan yang memiliki potensi besar untuk dikembangkan sebagai alternatif pemenuhan kebutuhan energi listrik yang ramah lingkungan. Salah satu teknologi yang terus dikembangkan adalah solar cell heterojunction berbasis Cu₂O/ZnO/FTO yang memanfaatkan kombinasi material semikonduktor tipe-p dan tipe-n untuk meningkatkan proses pemisahan serta transport pembawa muatan. Performa perangkat sangat dipengaruhi oleh kualitas lapisan penyusun yang dipengaruhi oleh parameter fabrikasi. Oleh karena itu, penelitian ini bertujuan untuk menganalisis pengaruh variasi temperatur pemanasan substrat FTO dan konsentrasi larutan prekursor ZnO terhadap performa solar cell heterojunction Cu₂O/ZnO/FTO serta mengevaluasi efisiensi konversi energi yang dihasilkan. Lapisan ZnO dideposisikan menggunakan metode spray pyrolysis pada temperatur 425°C, 450°C, 475°C, dan 500°C dengan variasi konsentrasi larutan ZnO sebesar 0,3 M:0,03 M; 0,4 M:0,04 M; dan 0,5 M:0,05 M. Selanjutnya, lapisan Cu₂O dibentuk menggunakan metode electrodeposition sehingga diperoleh struktur heterojunction Cu₂O/ZnO/FTO. Karakterisasi dilakukan melalui pengukuran parameter keluaran listrik yang meliputi open-circuit voltage (Voc), short-circuit current (Isc), daya keluaran (P), power density (Parea), dan efisiensi konversi energi. Hasil penelitian menunjukkan bahwa variasi temperatur pemanasan substrat dan konsentrasi larutan ZnO berpengaruh terhadap peningkatan karakteristik listrik solar cell. Kondisi optimum diperoleh pada konsentrasi ZnO 0,5 M:0,05 M dengan temperatur pemanasan 500°C yang menghasilkan nilai open-circuit voltage sebesar 120,5 mV, short-circuit current sebesar 145,8 mA, daya keluaran sebesar 17,57 mW, power density sebesar 0,234 mW/cm², dan efisiensi konversi energi sebesar 0,35%. Hasil penelitian menunjukkan bahwa peningkatan temperatur pemanasan substrat yang dipadukan dengan konsentrasi larutan prekursor ZnO yang tepat mampu menghasilkan lapisan ZnO dengan kualitas yang lebih baik sehingga meningkatkan performa solar cell heterojunction Cu₂O/ZnO/FTO.
