Abstract

Di desa Sungai Raya Kab. Bengkayang terdapat sungai yang memiliki kualitas fisik yang kurang baik terutama kekeruhan dan warna yang melebihi standar baku mutu air bersih, yaitu Sungai Baong. Agar dapat digunakan oleh masyarakat, diperlukan pengolahan khusus. Tujuan penelitian ini adalah Menganalisis kemampuan Tanah Kaolin dan Tawas sebagai koagulan dalam menurunkan kadar kekeruhan dan warna pada air Sungai Baong di Desa Sungai Raya, Kab. Bengkayang. Penelitian yang akan dilakukan bersifat eksperimen semu ( Quasi Experiment ) dengan populasi tanah kaolin dan tawas, dan sampel yang digunakan dalam penelitian ini, yaitu 30 sampel Air Sungai Baong dengan 5 kali berulang. Hasil penelitian dengan waktu pengendapan selama 30 menit mendapatkan dosis yang paling optimal kombinasi tanah kaolin sebanyak 5gr/l dan tawas sebanyak 0,2 gr/l, dengan penurunan kadar kekeruhan paling efektif, yaitu 5,97 NTU dari kadar sebelum perlakuan yaitu 1731 NTU dan penurunan kadar warna mencapai 18 TCU dari kadar sebelum perlakuan, yaitu 1321 TCU. Kesimpulan dari penelitian ini adalah terdapat perbedaan disetiap penambahan variasi dosis kombinasi Tanah Kaolin dan Tawas terhadap kekeruhan dan warna air sungai Baong sebelum dan sesudah perlakuan dengan nilai uji statistik kedua parameter, yaitu p= 0,000 (< 0,05).

Abstract

Penjamah makanan adalah seorang yang terlibat dalam satu rangkaian proses pengolahan makanan mulai dari persiapan, pemasakan, pendinginan, penyimpanan, pemanasan kembali dan penyajian makanan, dalam proses pengolahan makanan seseorang penjamah makanan dituntut untuk menerapkan personal hygiene yang baik agar tidak terjadi kontaminasi pada makanan yang diolah. Pada kebanyakan kasus, makanan terkontaminasi bukan secara sengaja tetapi karena perilaku kecerobohan penjamah makanan, penjamah makanan tidak menerapkan personal hygiene dan sanitasi selama bekerja. Tujuan penelitian ini adalah mendeskripsikan personal hygiene penjamah makanan pada rumah makan di wilayah kerja Puskesmas Parit Haji Husin II Kota Pontianak. Jenis penelitian ini adalah Deskriftif dengan pendekatan Observasional, yaitu melihat gambaran mengenai Personal hygiene penjamah makanan, seperti penerapan personal hygiene pada rumah makan. Hasil penelitian menunjukkan personal hygiene penjamah makanan yaitu 57 responden (87,69%) memenuhi syarat dan 8 responden (12,31%) tidak memenuhi syarat. Kesimpulan dalam penelitian ini adalah bahwa personal hygiene diwilayah kerja Puskesmas Parit Haji Husin II Kota Pontianak sebagian besar sudah memenuhi persyaratan personal hygiene sebanyak 87,69%. Dari 65 penjamah makanan yang terdiri dari 33 rumah makan, penjamah makanan yang memenuhi syarat personal hygiene sebanyak 57 responden (87,69%) dan yang tidak memenuhi syarat sebanyak 8 responden (12,31%).

Abstract

Household waste management is an important concern in an effort to reduce the potential negative impact on public health due to organic waste generation. This study aims to analyze differences in compost maturation rates based on variations in the time interval of the turning process in Magic Compost, differences in compost maturation rates based on the type of organic waste, differences in C/N ratio, carbon content, and moisture content in compost, differences in nitrogen, phosphorus, and potassium levels in compost, and differences in temperature, pH, and color in compost based on household organic waste criteria. This research uses an experimental approach with a posttest without a control group design and applies a randomized complete group design (RAKL). The tool used is Magic Compost, which is equipped with a temperature and humidity controller. The results showed a significant difference in the rate of compost maturation based on the time interval variation of the turning process on Magic Compost (p value = 0.000). The best turning time interval is 12 hours. There was a difference in the rate of compost maturation based on the type of organic waste generated by households, with mixed waste compost maturing the fastest and rice/starch waste maturing the slowest (p value = 0.001). While there was no difference in the C/N ratio (p value = 0.202), there were significant differences in the carbon content and moisture content of the compost based on the type of organic waste (p values = 0.042 and 0.000). However, there was no difference in the nitrogen and phosphorus content of the compost (p value = 0.144 and p value = 0.663). There was a difference in potassium levels in the compost based on the type of organic waste (p value = 0.000). The temperature of the resulting compost showed no significant difference (p value = 0.000), but there were differences in the pH and color of the compost based on household organic waste criteria (p values = 0.048 and 0.007). This study provides important insights into organic waste management through composting with Magic Compost, which can be an effective solution for reducing the negative public health and environmental impacts caused by organic waste generation.

Abstract

During working hours, Sales Promotion Girl (SPG) is standing in a shopping center, which can cause work fatigue. The objective of this study was to examine the work fatigue of SPG who wore high heels in various variations. The research design was cross-sectional, with the research subjects being 60 employees from the SPG in Pontianak Indonesia Mall. The L 77 reaction timer was employed to measure fatigue before and after work. The findings revealed that workers who wore 7 cm heels experienced higher levels of fatigue than those who wore 5 cm or 3 cm heels. The study results revealed no significant difference in fatigue before and after working various variations of high heels (p ≤ 0.001). When wearing high heels, the average level of fatigue increases. However, there was no statistically significant difference in heel height variation on fatigue level (p=0.173). When working in a standing position, wearing shoes with low heels increases comfort and reduces worker fatigue. The results of this study can be used as a starting point for future research by other researchers. Moreover, the findings of this study can also serve as a starting point for other researchers to conduct additional research.
