Abstract

Tujuan penelitian adalah menganalisis penggunaan media pembelajaran Kahitna Tampan CQR Paper Mode dalam meningkatkan keterampilan operasi hitung penjumlahan pada siswa kelas IV SDN Tegalrejo. Subjek penelitian adalah siswa kelas IV SDN Tegalrejo yang berjumlah 11 anak dan objeknya adalah keterampilan operasi hitung penjumlahan dengan menggunakan media pembelajaran Kahitna Tampan CQR Paper Mode. Metode pengumpulan data melalui kegiatan observasi untuk mengamati keterlaksanaan penggunaan media pembelajaran dan tes tertulis untuk mengetahui efektivitas media dalam meningkatkan keterampilan operasi hitung siswa melalui hasil belajarnya. Kemudian analisis data dilakukan dengan deskripsi kualitatif. Hasil penelitian menunjukkan bahwa penggunaan media pembelajaran Kahitna Tampan CQR Paper Mode dapat meningkatkan keterampilan operasi hitung penjumlahan. Berdasarkan asesmen diagnostik kognitif yang dilakukan sebelum pembelajaran diperoleh hasil rata-rata ketuntasan klasikal sebesar 54,5%. Sedangkan setelah pembelajaran menggunakan media pembelajaran Kahitna Tampan rata-rata ketuntasan belajar klasikal meningkat menjadi 81,18% dengan persentase ketarampilan operasi hitung sebesar 81,06 atau berada pada kategori terampil.

Abstract

A candlenut peeling machine is a technological innovation aimed at improving the efficiency of separating candlenut seeds from their shells. Hand-peeling candlenuts requires a lot of time and effort, and it carries a high risk of damaging the candlenut kernels due to uneven impact. This candlenut peeling machine is equipped with a mechanism that reduces seed damage and increases productivity. The machine can be operated manually or semi-automatically and works on the principle of utilizing pressure and friction to break the shell without damaging the seeds inside. Experimental results show that this machine has a high success rate in separating candlenut seeds from their shells and reduces the number of damaged seeds compared to traditional methods. The use of this machine aims to increase the productivity of candlenut farmers and add value to the candlenut processing industry.

Abstract

River water plays an important role in human life. Along with the increasing population and waste problems generated from human activities, climate change is a factor that also affects river water quality. Blankahan Village is located in Langakat District, with 3 interconnected rivers, Palma River, Pekan Kuala, and Dosi Valley. This program examines the impact of river water quality on public health in Blankahan Village, with a focus on physico-chemical and social health analysis to support the achievement of SDGs points 3 and 6. It was found to be in a fairly poor and murky condition according to the classification according to Government Regulation Number 22 of 2021. Furthermore, based on statistical tests and One Way ANOVA Tests indicated that there was no statistically significant difference in the mean perception among the age groups. Some indicated women's health problems due to river water use such as dermatitis, skin diseases, and diarrhea continue to increase. River water sources are still used by some communities to fulfill household needs during the dry season despite many negative perceptions that river water quality is poor, dirty and polluted with waste. River water quality is influenced by seasonal factors and pollution, namely the difference in river water quality during the rainy and dry seasons, and is also caused by domestic waste, livestock waste, and industrial waste entering the water.
