Abstract

Menurut badan Kesehatan dunia WHO Indonesia menempati urutan keempat terbanyak penderita diabetes militus di dunia yaitu 8,4 juta setelah India 31,7 juta, Cina 20,8 juta, dan Amerika Serikat 17,7 juta jiwa. Dan diperkirakan jumlah akan meningkat hampir tiga kali lipat pada tahun 2030, yaitu dari 8,4 juta menjadi 21,3 juta orang. Peningkatan ini dipicu oleh jenis makanan yang di komsumsi dan kurang melakukan olah raga di sisi lain. Berbagai obat berbasis kimiawi dengan berbagai variasi harga telah banyak tersedia. Namun obat berbasis alami juga mulai banyak diperkenalkan ke masyarakat. Tumbuhan galing-galing (Cayratia trifolia) satu diantarnya yang bisa dipakai sebagai obat alternatif alami yang perlu diperkenalkan. Ternyata cairan galing-galing mempunyai kasiat sebagai antidiabetes, melindungi dan memulihkan hati dari racun, menurunkan kandungan kolesterol dalam darah, menurunkan kandungan gula dalam darah, meningkatkan kekebalan tubuh, sebagai antioksidan, antivirus, antibakteri, dan antikanker. Pengabdian kali ini berfokus pada pengenalan tanaman galing ke ibu-ibu PKK RW 03 Kelurahan Semolowaru, Kecamatan Sukolilo-Surabaya. Dan ternyata diketahui bahwa hampir semua (94%) ibu-ibu PKK sama sekali belum mengenal tanaman galing-galing apa lagi bagaimana memanfaatkan sebagai obat alternatif penurun diabetes militus. Setelah dilakukan pelatihan dan terapi cairan galing-galing, dapat disimpulkan bahwa (1) cairan galing memang benar-benar dapat menurunkan kandungan gula dalam darah bagi pasien Diabetes Melitus, (2) mengetahui budidaya tanaman galling-gaing setelah mengetahui cara tanam yang mudah dilakukan.

Abstract

PT. Romi Violeta is a furniture company engaged in the production of rattan and wood products for the global market. The problem that often occurs is that the Finger Joint machine often experiences damage to the engine components. Therefore, the objectives of this research are to identify critical components in the Finger Joint machine, develop a maintenance scheduling for the machine's components, and compare the maintenance costs before and after implementing the scheduling. The analysis revealed that the Hydraulic component has a cumulative value of 40%, followed by the Cutter component with a cumulative value of 34.4%, and the Air Hose component with a cumulative value of 5.6%. Consequently, a preventive maintenance schedule was determined, with the Hydraulic component requiring maintenance every 31 days, the Cutter component every 36 days, and the Air Hose component every 207 days. This resulted in a reduction in maintenance costs from the previous amount of Rp.5,200,000 to Rp.1,210,847.

Abstract

PK. Rosella Baru is a company operating in the plastic sack industry. In the production process of plastic sacks, there are several stages, including the production of plastic thread. The company still encounters a significant number of defects in the plastic thread, exceeding 2%, resulting in obstacles in the weaving process of the sacks and suboptimal production output. The research utilizes the Statistical Process Control method to identify solutions for quality control of the plastic thread products at PK. Rosella Baru. Based on the Pareto diagram, the most dominant defect is found in the unevenness of thread rolls, accounting for 43.3% of the defects. The control chart analysis shows that there are samples exceeding the upper control limit (UCL) in samples 1 and 9, and data exceeding the lower control limit (LCL) in samples 3 and 6. The cause and effect diagram identifies five factors: labor, machine, material, method, and environment. The most dominant cause is the lack of training for the workforce and insufficient maintenance of the machines, resulting in defective plastic thread. Therefore, the suggested solution is to perform regular machine maintenance, provide training to the workforce, and pay attention to machine settings and the quality of raw materials used.
