Abstract

One of the most dangerous environmental factors is noise, which is crucial to control. This research aims to determine the differences in silencer media thickness between patchwork and plywood offsets to reduce noise intensity in cutting yarn engines. The method study characteristic experiment with design research conducted in this study used a design pretest-posttest without control. The population in this study is the whole room production source producing intensity noise by PT Trisula Textile Industries. Sample in the study This machine is cutting yarn, which produces the most noise. Purposive sampling is the technique used to conduct sample studies. e in six repetitions, with 36 temperature and moisture measurements. The measurement of the intensity of noise at the source of noise before being given treatment ranged from 97.26 to 97.43. The results of the decline in noise intensity after a given silencer show that variation 1 decreased the average by 5.66%, variation 2 decreased the average by 8.89%, and variation 3 lowered the average by 11.89% dB. We processed the data using the one-way ANOVA test, and the results showed a P value of 0.0001 (significant), which is less than 0.05, which indicates a significant difference in each variation of thickness. Industry can use thicker plywood thickness boards if applied in areas with a higher noise level and install a wheel on a tool reducer that can be used practically. Further, researchers can use different types of damping media and vary the thickness of the cloth patch.

Abstract

ABSTRAK Telur adalah jenis bahan pangan yang rentan terhadap kerusakan, baik dari segi fisik, kimia, maupun biologi, karena kandungannya yang kaya akan nutrisi yang dibutuhkan untuk pertumbuhan mikroorganisme. Telur merupakan salah satu makananan yang mengandung bakteri  Staphylococcus aureus. Salah satu upaya untuk memperpanjang masa simpan telur dengan cara dioleh menjadi pindang telur dengan menggunakan Daun jambu biji (Psidium guajava). Tujuan penelitian ini untuk mengetahui pengaruh pemanfaatan daun jambu biji  (Psidium guajava L.) sebagai pengawet alami dalam memperpanjang  masa simpan pindang telur. Jenis penelitian ini adalah eksperimen, rancangan sampel menggunakan rancangan acak lengkap dengan 3 perlakuan 6 pengulangan dan 1 kontrol. 1 perlakuan menggunakan 4 buah telur, sehingga  besaran sampel pada penelitian ini sebanyak 72 butir telur. Analisis data menggunakan ONE WAY ANOVA, yaitu untuk melihat perbedaan rata-rata masa simpan pindang telur  dan melihat perbedaan rata-rata penurunan jumlah angka Staphylococcus aureus pada tiap dosis. Hasil penelitian menunjukkan ada perbedaan masa simpan pindang telur diantara ketiga dosis daun jambu biji ( 50 gr, 100 gr dan 150 gr) dengan p-value= 0.000 pada alpha 5 %, ada perbedaan rata-rata penurunan jumlah angka Staphylococcus aureus  pada pindang telur diantara ketiga dosis daun jambu biji( 50 gr, 100 gr dan 150 gr dengan p-value= 0.000. Disarankan untuk melakukan pembubuhan dosis   daun jambu biji (Psidium guajava)  dengan dosis 150 gr untuk memperpanjang masa simpan pindang telur selama 9 hari

Abstract

Pendahuluan: Peralatan makan yang tidak memenuhi syarat bakteriologis dapat menjadi sumber penyakit. Kontaminasi bakteri sering disebabkan oleh proses pencucian yang tidak tepat. Selain membersihkan kotoran, sabun pencuci diharapkan mampu mengurangi mikroorganisme pada alat makan. Penambahan bahan alami seperti ekstrak bunga pukul empat (Mirabilis jalapa) yang mengandung flavonoid dan saponin memiliki potensi antibakteri. Metode: Kegiatan ini melibatkan pelatihan pembuatan sabun pencuci piring cair dengan bahan tambahan larutan daun bunga pukul empat. Sasaran kegiatan adalah kader kesehatan di RW 01, Kelurahan Sukawarna, Kota Bandung. Metode meliputi penyuluhan, pelatihan praktis, dan pendampingan dalam pembuatan sabun cair. Hasil: Terdapat peningkatan tingkat pengetahuan peserta dari skor rata-rata 54 menjadi 75,5 setelah pelatihan. Kader kesehatan menunjukkan antusiasme tinggi dalam praktik pembuatan sabun cair berbahan alami. Kesimpulan: Pelatihan ini memberikan manfaat berupa peningkatan pengetahuan kader kesehatan tentang pembuatan sabun pencuci alat makan yang efektif dan ekonomis. Inovasi menggunakan ekstrak bunga pukul empat sebagai bahan tambahan pada sabun cair membantu masyarakat mengurangi pengeluaran serta meningkatkan kebersihan peralatan makan.

Abstract

The problem of food sanitation hygiene was very important to be addressed, especially in food management facilities such as office canteens. It was found that the number of germs on cutlery in the PT X canteen exceeded the established quality standard, namely 150 colonies/cm2. Attempts to reduce the number of germs on the cutlery of dishes by sterilization using UV-C light. This study aims to determine the variation in power and the length of contact time of ultraviolet lamp type C (UV-C)  using a sterilization cabinet against reducing the number of germs on the cutlery at PT.X This type of research is an experiment with a posttest with control design. The cutlery used as a sample was 25 pieces. Data analysis was bivariate statistic analysis.  Based on the results, it was known that there was a decrease in the number of germs after UV-C light irradiation was carried out. Irradiation with a power of 15 watts long contact 25 minutes lowers the number of germs 96.89%, Irradiation with a power of 15 watts long contact 30 minutes lowers the number of germs 98.65%, Irradiation with a power of 30 watts long contact 25 minutes lowers the number of germs 99.89%, and Irradiation with a power of 30 watts long contact 30 minutes decreases the number of germs 100%. A decrease in the number of effective germs occurs at a lamp power of 30 watts with a time contact duration of 30 minutes.

Abstract

Noise is one of the most dangerous factors in the work environment, so it is essential to control it. This study aims to determine the variation in the thickness of the damping medium from patchwork and plywood waste, with a focus on reducing the intensity of noise in yarn cutting machines. This study iThis study employs an experimental pretest-posttest design without a control group. population comprises all noise sources present in the production room of PT Trisula Textille Industries. The yarn-cutting machine with the highest noise is the sample used in this study. The sampling technique is purposive sampling. The test was carried out on 36 noise, temperature, and humidity measurement results. The results of noise intensity measurements before treatment ranged from 97.26–97.43 dBA. After applying variance 1 dampers, the average noise intensity decreased by 5.66%, variation 2 by 8.89%, and variation 3 by 11.89%. The one-way ANOVA test shows a p value of 0.0001 or < 0.05. According to the decision rules, it means that there is a difference in each thickness variation has a difference. When applied in areas with high noise levels, industries can use thicker plywood boards and install wheels on the dampers so that the tools can be used practically. Researchers can then use different types of damping media and thicker patchwork variations.
