Abstract

Perusahaan Daerah Air Minum (PDAM) Way Rilau Kota Bandar Lampung mengolah air sungai Way Kuripan sebagai baku air bersih. Hingga saat ini, pemantauan kekeruhan dan padatan terlarut (TDS) air baku untuk menentukan dosis koagulan dalam pengolahan air masih dilakukan secara konvensional. Sementara, kualitas fisik air baku bersifat fluktuatif, terutama dipengaruhi curah hujan. Akibatnya, seringkali dosis tidak cukup untuk proses koagulasi/flokulasi sehingga air olahan masih keruh. Penelitian bertujuan membuat prototype alat pengukur kekeruhan dan TDS berbasis Internet of Things dengan sistem sensor. Alat dikembangkan menggunakan microcontroller ATMega-328P, sensor kekeruhan TS-300B, sensor TDS ESP-8266, dan modul SIM-800L V.2. Prinsip kerja alat dengan menangkap nilai kekeruhan dan TDS oleh sistem sensor, selanjutnya data diolah oleh microcontroller dan diteruskan melalui Modul SIM800L V.2 ke penerima (smartphone/PC) melalui jaringan internet. Hasil penelitian mendapatkan tingkat akurasi yang tinggi pada pengukuran kekeruhan (96,89%) dan TDS (97,55%). Analisis statistik tidak menunjukkan perbedaan hasil pengukuran antara prototype dengan alat ukur standar pada kedua parameter (p-value>0,05). Sedangkan kecepatan transfer data selama 30 detik. Hasil penelitian ini menunjukkan bahwa prototype mampu memberikan hasil pengukuran kekeruhan dan TDS secara valid, berbiaya murah, dan real time.

Abstract

Pesticide poisoning is still an important health problem in agricultural areas, especially horticultural agriculture. Various chronic health effects can be caused by long-term exposure to pesticides. This study aims to determine the risk factor of pesticide poisoning in horticultural farmers in West Lampung Regency.The study used a cross sectional design which was conducted in four different areas as the center of horticulture agriculture, West Lampung Regency, Lampung Province. The study involved 289 participants by interviewing, observing and examining blood samples to measure cholinesterase levels as an indicator of pesticide poisoning. In this section, we have applied research ethical procedures. The obtained data were analyzed using Chi squre test, Odds Ratio test and Logistic Regression.The results showed that the risk factors for pesticide poisoning were incomplete use of personal protected equipment (PPE), spraying with the wrong dose and spraying frequency. Unwearing a complete PPE had a 4.54 times (OR = 4.54; 95% CI 2.09-9.83) higher risk of experiencing pesticide poisoning, and statistically suggested, a very significant relationship (p = 0.0001). While the use of excessive dosage has a risk of 4.39 times (OR = 4.39; 95% CI 1.87-10.33; p = 0.001); and the frequency of spraying more than twice a week had a 2.33 times higher risk of experiencing pesticide poisoning (OR = 2.33; 95% CI 1.24-4.40; p = 0.009).Excessive use of pesticide dosage and the frequency of spraying with the cover blanked method are the main factors of pesticide exposure to farmers. On the other hand, the use of PPE is a method of protection from exposure. It needs joint efforts through increasing knowledge about the dangers of pesticides, pesticide management, how to work safely, and the use of PPE.

Abstract

PT Sinar Laut Indah is a concrete manufacturing plant that has a risk of occupational accidents and occupational diseases due to exposure to particulates, use of work tools, and work methods. The purpose of this research is to find out what are the dangers in a factory, to assess the risk (risk assessment) and risk control (risk control) at each work stage using the HIRARC method.The work risk assessment uses the HIRARC method, which consists of three stages of assessment, namely hazard identification, risk assessment and risk control. The research subjects were all activities in the paving block production section including tools, materials and work processes. Data collection was carried out by observing and measuring exposure, which was then standardized using two risk assessment parameters, namely probability/likelihood of hazard and severity of the hazard. Risk control is the final stage formulated based on the results of the risk assessment from the previous stage.The results of the study found 4 activities in the high category, mixing and stirring of materials, checking rolling boxes, paving blocks presseing, and cleaning the remaining material. The highest risk of occupational diseases is respiratory problems and skin or eye irritation during the mixing and stirring activities of the ingredients, as well as cleaning the remaining materials. Meanwhile, the highest risk of work-related accidents is in rolling box-checking activities.The use of the HIRARC method and the application of probability/likelihood of hazard and severity of hazard are good enough to assess the risk of occupational accidents and occupational diseases. Carrying out repair and maintenance of machines, determining danger zones, using personal protective equipment, and administrative controls are efforts that must be made to avoid risks due to work

Abstract

An eye injury is a trauma to the eye that can result in damage to the eyeball, eyelids, eye nerves and orbital cavity. Eye injuries can occur due to work processes in various industries, especially in the metal industry. PT. Bakrie Pipe Industry (BPI) is a metal industry that produces steel pipes by changing steel plate sheets into pipe shapes. One of the risks of work accidents in the production process is eye injury due to exposure to particles/gram of iron during the cutting process. This study aims to determine the risk factors for eye injury in workers in the Production Department of PT. Bakrie Pipe Industries, Bekasi, West Java.This study used a cross-sectional design involving all workers in the Production Department as research subjects, as many as 36 people. Data collection was carried out by interview and observation, then the data were analyzed using the chi-square test. The risk factors assessed were age, knowledge, attitude, noise and personal protective equipment against eye injury.The results showed that the risk factors for eye injury were knowledge (OR = 280.00; p value = 0,000), age (OR = 61.75; p value = 0,000), noise (OR = 39.00; p value = 0,000). , and the use of PPE (OR = 17.00; p value = 0.001).Increasing workers' knowledge about work risks is an effort that must be continuously carried out to avoid eye injuries, in addition to the necessity of using Personal Protective Equipment (PPE), and to carry out more intensive supervision.

Abstract

The increase in population due to the birth rate has put pressure on meeting the water needs of the people. In 2050, the global demand for clean water is to meet the needs of 9.7 billion people. One of the strategies developed for sustainable water use is rainwater harvesting (RWH). From many reports, the RWH system can meet household water needs. However, it needs special attention from the quality aspect due to pollution. This paper presents the factors affecting water quality in the RWH system through three stages. The first stage is when rainfall clears pollutants in the air. In the second stage, the rain removes dirt and particles in the catchment area—the third, flushing dirt on pipes and storage tanks. Maintenance must be done to all parts of the RWH system periodically and must be treated and disinfection before being used as drinking water.

Abstract

Dengue fever (DHF) is an infectious disease caused by the dengue virus through the Aedes aegypti mosquito vector. The use of repellents is an effort to prevent mosquito bites. One of the potential natural ingredients used as a repellent is zodia leaves (Evodia suaveolens) because they contain up to 46% linalool. This study aims to measure the effectiveness of the essential oil from zodia leaves as a repellent. The study was conducted on a laboratory scale following WHOPES recommendations. A total of 960 adult Ae.aegypti mosquitoes (aged 2-5 days) from the rearing process were used in this study. Five volunteers participated as probands. The essential oil is distilled from fresh azola leaves with 70% ethanol as solvent. The repellent lotion is made using an essential oil, lanolin, stearic acid, and other substance. The experiment used an arm-in-cage with two replication and 20 mosquitoes for each treatment. The concentrations tested were 1%, 2%, 3%, with 0% control. The number of mosquitoes that arrived was recorded after using the repellent for 15, 30, 60, 120, 240, and 360 minutes. The study found a significant effect of concentration (p-value <0.0001) and contact time (p-value <0.0001) on the number of mosquitoes that landed. Zodia leaf lotion (Evodia suaveolens) with a concentration of 3% can protect 50% up to 360 minutes after use. Further research is needed to get a concentration that can provide 95% protective power after 30 minutes of use and 90% after 360 minutes

Abstract

Malaria is one of the public health problems that can cause death in infants, children under five, pregnant women and reduces work productivity. Vector control by chemical means leads to vector resistance and environmental pollution and negatively impacts public and animal health. This study aims to determine the effectiveness of the bark extract of Maja (Aegle marmelos L) against the death of Anopheles sp mosquito larvae with concentrations of 5%, 10%, 20%, 40%, and 50% and the observation of contact times every 15 minutes, 30 minutes, 60 minutes, 90 minutes and 120 minutes. The study used a Completely Randomized Design (CRD) with Factorial. Extraction used maceration method, with 70% ethanol as solvent. Larvae of Anopheles sp. instar III obtained from malaria endemic area. The test used a 200 ml container, with two replications. All data were analyzed by two way ANOVA and Tukey HSD test. This study obtained mortality of 93.3% larvae at a concentration of 50% and a contact time of 120 minutes. The results of statistical analysis showed a significant effect of concentration (p=0.0001), contact time (p=0.0001), and interaction concentration-contact time (p=0.004) on the mortality of Anopheles sp. mosquito larvae. This study has proven the use of bark extract of Maja (Aegle marmelos L) as an alternative bio-insecticide in controlling mosquito larvae of Anopheles sp.

Abstract

Demam berdarah dengue (DBD) adalah penyakit infeksi yang ditularkan melalui nyamuk Aedes aegypti dan Ae. albopictus yang terinfeksi. Kasus DBD meningkat 30 kali lipat dengan peningkatan ekspansi geografis ke negara-negara baru dan dalam dekade ini, dari kota ke lokasi pedesaan. Oleh karena itu perlu dilakukan upaya pencegahan penularan, salah satunya dengan repellent anti nyamuk. Tujuan penelitian ini adalah untuk mengetahui kemampuan ekstrak daun cengkeh (Syzygium aromaticum) sebagai repellent semprot nyamuk Aedes aegypti. Eksperimen menggunakan 100 ekor nyamuk Ae. aegypti dewasas (usia 2-5 hari) yang dikembangkan di Laboratorium Entomologi Lokalitbang Kementerian Kesehatan Baturaja. Pengujian dilakukan terhadap lima orang probandus (relawan berusia 18-25 tahun) yang dipaparkan dengan ekstrak daun cengkeh pada lima konsentrasi (3%, 5%, 7%, 9%, dan 12%), selama enam jam. Pengumpulan data dilakukan setiap jam, selanjutnya dianalisis dengan ANOVA. Penelitian mendapatkan bahwa ekstrak daun cengkeh mampu menolak nyamuk hinggap secara signifikan (p-value=0,010). Rerata terendah nyamuk hinggap pada konsentrasi 12% (1,5 ekor), dengan trend selama enam jam sebanyak 2,5 ekor. Namun, hasil perhitungan daya proteksi baru mencapai 43,7%., sehingga belum masuk kategori efektif (80%). Penelitian telah membuktikan bahwa ekstrak daun cengkeh (Syzygium aromaticum) dengan aplikasi spray, dapat menjadi alternatif repellent nyamuk Ae.aegypti. Perlu penelitian lanjutan untuk mendapatkan konsentrasi yang efektif.
