Abstract

This Floods occur frequently in Indonesai also in Jayapura, one of the negative impacts being felt on the world of education, namely the damage to educational facilities and infrastructure, including damage to the tools used to carry out physics practicums at SMA Negeri 4 Jayapura. Efforts to continue to carry out practicum activities are by utilizing applications found on smartphones as practicum media including the EveryCircuit application and Logic Circuit Simulator in electrical experiments. In carrying out the activity, no significant obstacles were found because the students were accustomed to using smartphones and easily understood the use of the given application because a practicum guidebook was available. The EveryCircuit application and Logic Circuit Simulator can be used as a tool to be used as a virtual laboratory in carrying out physics practicums in schools, especially in the learning process during the post-disaster period and for schools that do not yet have a laboratory or special equipment in the electronics field. Keywords: the everycircuit application; logic circuit simulator; educational facilities and infrastructure; education

Abstract

Telah dilakukan penelitian analisis kosntanta dilektik dan pengukuran total padatan atau partikel terlarut dalam air danau Sentani. Penelitian ini dilakukan untuk mengetahui besar nilai dari konstanta dielektrik dan nilai padatan yang terlarut pada air danau sentani. Penelitian ini mengambil sample di sekitran kampung yoboi kabupaten Jayapura. Dimana dari penelitian ini didapatkan rata rata nilai padatan 112.8 ppm. Untuk penentuan konstanta dielektrik tiap konsentrasi larutan dilakukan pengukuran kapasitansi dengan variasi jarak antar plat. Sebelum pengukuran konstanta dielektrik larutan, dilakukan kalibrasi dahulu terhadap alat dengan mengukur konstanta dilektrik udara dan didapatkan nilai sebesar 1,05. Nilai ini berbeda dengan konstanta dielektrik udara referensi sebesar 1,00054 sehingga didapatkan eror sebesar 4,9 %. Nilai eror ini masih dalam tahap wajar sehingga alat dapat digunakan untuk mengukur konstanta dielektrik larutan. Pengukuran kapasitansi dilakukan dengan range frekuensi 100 – 2000 Hz dengan interval 50 Hz. Hasil penelitian menunjukkan bahwa metode dielektrik dapat digunakan untuk mengukur nilai kapasitansi dan konstanta dielektrik pada cabe air danau sentani. Nilai kapasitansi dan konstanta dielektrik semakin menurun dengan bertambahnya frekuensi.

Abstract

Laundry activities utilizing detergents as cleaning agents generate non-degradable waste, posing environmental and health hazards. Laundry services, or laundries, have experienced rapid growth in Jayapura City, resulting in substantial laundry waste discharge directly into the environment. Activated carbon, with its porous and highly absorptive nature, proves effective to absorb waste particles. This community engagement initiative focuses on providing education and implementing small to medium-scale laundry waste treatment for micro, small, and medium-sized enterprises. The project collaborates with Zifara Laundry, a laundry business located in Waena, Heram District, Jayapura City. The partner receives essential education on the importance of pre-treating laundry waste before disposal into the environment. The engagement team installs waste filters based on activated carbon, augmented with silica sand, gravel, and cotton filters in each layer. As a result, both the business owner and laundry workers gain a profound understanding of the significance of treating laundry waste before environmental discharge. The waste filters installed by the engagement team on the central laundry waste disposal channel contribute to an improvement in laundry wastewater quality. Turbidity levels decrease from a scale of 150-200 NTU to 1-2 NTU after the installation of activated carbon-based laundry waste filters.
