    Perusahaan peti kemas merupakan perusahaan jasa bongkar muat yang memiliki beberapa peralatan kerja untuk mendukung proses bongkar muat. Salah satu peralatan yang digunakan adalah Reach Stacker (RS). RS  merupakan salah satu peralatan yang fleksibel dan tidak terbatas ruang geraknya. Penggunaan RS ini sering kali mengalami kegagalan, sehingga dapat menghambat proses kerja. Kegagalan yang terjadi seperti subkomponen pada engine yaitu accu mengalami kerusakan dan twistlock error/mace . Dengan adanya potensi kegagalan ini peneliti menggunakan metode Failure Mode and Effect Analysis (FMEA) dan Pareto Diagram untuk membantu dalam mengevaluasi kegagalan yang terjadi pada peralatan dengan memperhatikan nilai perkalian SOD yang akan menjadi nilai Risk Pririty Number (RPN). Untuk menentukan nilai kekritisan digunakan diagram pareto. Berdasarkan hasil dari pembuatan FMEA didapatkan 9 komponen dan 40 subkomponen. Didapatkan hasil  39 failure mode dari 39 subkomponen. Dari perhitungan RPN didapatkan twislock memiliki RPN tertinggi dengan skor 168, kemudian dengan skor 90 subkomponen accu dan brake. Kemudian hasil RPN dicari kekritisan komponenya dari pareto didapatkan 11 subkomponen yang masuk dalam kategori kritis yang selanjutnya akan dianalisa untuk diberikan rekomendasi perawatan. Dari hasil analisis menggunakan ketiga metode ini diharapkan dapat membantu perusahaan dalam menjaga keandalan dari Reach Stacker (RS) sehingga dapat menjaga produktivitas kerja Reach Stacker (RS)

    Telah dilakukan penelitianuntuk mengetahui potensi energi angin di wilayah Kalimantan Barat. Perhitungan potensi energi angin menggunakan data kecepatan angin tahun 2006 s.d. 2015 di 14 kabupaten/kota. Data tersebut diolah dengan menggunakan software surfer dan dianalisis berdasarkan empat kondisi musim di Indonesia.Hasil perhitunganmenunjukanrata-rata daya listrik tertinggi pada Musim Barat, Musim Timur dan Musim Peralihan II per wilayah di Kalimantan Barat berada di Kabupaten Ketapang dengan nilai berturut-turut yaitu 562,22 Watt, 1013,39 Watt dan 173,18 Watt. Hasil yang sangat berbeda diperoleh Musim Peralihan I dimanarata-rata daya listriknya hanya berkisar antara 0,10 s.d 0,77 Watt. Hal tersebut menunjukan daya listrik tertinggi terjadi pada Musim Timur dan berada pada Kabupaten Ketapang dengan nilai sebesar 1013,39 Watt. Namun dengan daya listrik tersebut Kabupaten Ketapang belum berpotensi menghasilkan daya listrik kontinu di Kalimantan Barat.  Kata kunci :EnergiAngin, Daya Listrik, Kalimantan BaratTelah dilakukan penelitianuntuk mengetahui potensi energi angin di wilayah Kalimantan Barat.

    Biofilter aquaponic system for nutrients removal from fresh market wastewater

    Get PDF
    Aquaponics is a significant wastewater treatment system which refers to the combination of conventional aquaculture (raising aquatic organism) with hydroponics (cultivating plants in water) in a symbiotic environment. This system has a high ability in removing nutrients compared to conventional methods because it is a natural and environmentally friendly system (aquaponics). The current chapter aimed to review the possible application of aquaponics system to treat fresh market wastewater with the intention to highlight the mechanism of phytoremediation occurs in aquaponic system. The literature revealed that aquaponic system was able to remove nutrients in terms of nitrogen and phosphorus

    A single-center non-blinded randomized clinical trial to assess the safety and effectiveness of PhR160 spray in the treatment of COVID-19 pneumonia

    7-16COVID-19 is an emerging pandemic that caused a very widespread infection with more than 1000000 cases in Iran within a year. The main cause of mortality among patients with COVID-19 is pulmonary failure. In Iranian Traditional Medicine, essences have been used for curing pulmonary diseases. Pinen-Hydronoplacton-Ribonucleic acid (PHR) is an inhaler spray made of seven different plants, which all are used by humans and have desirable pharmacological features for treating pulmonary symptoms of COVID-19 patients. This study was conducted to assess the safety and effectiveness of PHR160 spray in improving pulmonary symptoms of COVID-19 patients. This was a single-centre, non-blinded randomized clinical trial with two parallel groups in two different wards of Baqiyatallah hospital, Tehran, Iran. Participants were 63 male patients diagnosed with COVID-19 pneumonia, divided into 2 groups of 32 in the intervention group and 31 in the control group. The intervention group received 5 days of PHR160 spray, 10 puffs each day, 300 micrograms in each puff in addition to the routine treatment. Oxygen saturation was measured by a pulse oximeter, every six hours and recorded daily. This study showed that administration of PhR 160 in patients of COVID-19 was safe, and it significantly increased the arterial oxygen saturation percentage in COVID-19 patients. In addition, it decreased hospitalization duration, dyspnea score, and cough score significantly in the patients. The statistical modelling test, with adjusting the age and respiratory rate for baseline and 4 days of the intervention, shows that the oxygen saturation percentage mean was significantly more in the intervention group by 5.14 units (p<0.001)

    Honey, a Gift from Nature to Health and Beauty: A Review

    Get PDF
    Benefits of honey are contributed by the composition of its elements such as glucose, fructose, glucose oxidase, vitamins and phenolic compounds. For health, honey can be used to treat wounds due to the antibacterial activity conferred by the hydrogen peroxide produced by glucose oxidase in honey. Anti-inflammatory, anti-oxidant, deodorizing and tissue regeneration activities in honey also help in the wound healing process. It can also be an alternative sweetener for diabetic patients to ensure compliance to a healthy diet. Moreover, honey exerts several effects such as lowering low density lipids and increasing high density lipids, thus reducing risk of atherosclerosis. In terms of beauty, honey can be used on skin and hair. It moisturizes skin through its natural humectant properties contributed by high contents of fructose and glucose. Honey treats acne on the skin due to its antibacterial activity, anti-inflammatory action and tissue repair. The hair can benefit from honey in such a way that the hair has abundance, and becomes easier to comb. However, there have not been as many studies regarding the use of honey in skin in comparison to its use for health. Therefore, future studies on honey could research its use, action and benefits in both cosmetics and dermatology

    Mapping inequalities in exclusive breastfeeding in low- and middle-income countries, 2000–2018

    Get PDF
    Exclusive breastfeeding (EBF)-giving infants only breast-milk for the first 6 months of life-is a component of optimal breastfeeding practices effective in preventing child morbidity and mortality. EBF practices are known to vary by population and comparable subnational estimates of prevalence and progress across low- and middle-income countries (LMICs) are required for planning policy and interventions. Here we present a geospatial analysis of EBF prevalence estimates from 2000 to 2018 across 94 LMICs mapped to policy-relevant administrative units (for example, districts), quantify subnational inequalities and their changes over time, and estimate probabilities of meeting the World Health Organization's Global Nutrition Target (WHO GNT) of ≥70% EBF prevalence by 2030. While six LMICs are projected to meet the WHO GNT of ≥70% EBF prevalence at a national scale, only three are predicted to meet the target in all their district-level units by 2030.This work was primarily supported by grant no.

    Search for dark matter produced in association with a Higgs boson decaying to a pair of bottom quarks in proton-proton collisions at root s=13TeV

    Get PDF
    A search for dark matter produced in association with a Higgs boson decaying to a pair of bottom quarks is performed in proton-proton collisions at a center-of-mass energy of 13 TeV collected with the CMS detector at the LHC. The analyzed data sample corresponds to an integrated luminosity of 35.9 fb(-1). The signal is characterized by a large missing transverse momentum recoiling against a bottom quark-antiquark system that has a large Lorentz boost. The number of events observed in the data is consistent with the standard model background prediction. Results are interpreted in terms of limits both on parameters of the type-2 two-Higgs doublet model extended by an additional light pseudoscalar boson a (2HDM+a) and on parameters of a baryonic Z simplified model. The 2HDM+a model is tested experimentally for the first time. For the baryonic Z model, the presented results constitute the most stringent constraints to date.Peer reviewe
