A sensitive spectrophotometric method for the determination of micro-amounts of phosphorus existing as orthophosphate is proposed. The method is based on a filtration–dissolution preconcentration and flow injection with spectrophotometric detection. In an acidic medium orthophosphate reacts with molybdate to form molybdophosphate, which then reacts with a cationic dye, Malachite Green (MG), to form a coloured ion associate. The ion associate is filtered through a membrane filter (cellulose nitrate; pore size 1.0 µm, diameter 9 mm), then dissolved together with the membrane filter in methyl Cellosolve and their absorbance measured at 627 nm with a flow injection system equipped with an autosampler. For the filtration of the ion associate, a filtration apparatus was designed. The laboratory-made filter holders were made of poly(chlorotrifluoroethylene) and poly(tetrafluoroethylene)(PTFE) and were equipped with a 50 cm³ separating funnel. The filter holders were connected to an aspirator. For the measurement of absorbances of the methyl Cellosolve solutions, a flow injection system was assembled by using a double-plunger micropump, an autosampler, spectrophotometric detector with a 10 mm flow-through cell and a recorder. All of the flow lines were made of 0.5 mm i.d. PTFE tubing. The calibration graph was linear up to 18 ng cm^–3 of phosphorus using a 10 cm^–3 sample, and the limit of detection was 60 ppt of phosphorus. Using the proposed method, phosphorus in sea-water was determined.

The occurrence of COVID-19 has a psychological impact on the elderly which will affect mental health and quality of life. This study aimed to identify the relationship between depression, anxiety, coping strategies with the quality of life of the elderly. This cross sectional study was conducted during the COVID-19 pandemic. Cluster sampling technique was used to select 232 sample. This study employed geriatric depression scale (GDS 15) to measure depression, the geriatric anxiety inventory (GAI) to measure anxiety, brief resilient coping skala (BRCS) to measure coping stratecgies, and the WHOQOOL-BRIEF questionnaire to measure quality of life among the elderly. Data analysis used Multiple Linear Regression statistical test. This study showed that there is a correlation between depression and quality of life (p=0.000), anxiety and quality of life (p=0.000) with coping strategies and quality of life (p=0.027). This study recommended the provision of appropriate psychological interventions to improve and maintain the quality of life among the elderly.

Latar Belakang: Prevalensi penyakit kronis terutama diabetes melitus (DM) dan hipertensi pada lanjut usia (lansia) terus meningkat. Hal ini berisiko menimbulkan kecacatan, penurunan kualitas hidup, bahkan kematian. Sebagian besar lansia mengeluh mengalami gangguan tidur sehingga mempengaruhi status kesehatan dan kualitas hidup. Aspek psikologis diidentifikasi sebagai salah satu faktor penyebab utama masalah tidur pada lansia penderita DM dan hipertensi.Tujuan: Menganalisis hubungan kondisi psikologis dengan kualitas tidur lansia penderita DM dan hipertensi.Metode: Penelitian dilakukan dengan pendekatan cross sectional di Puskesmas Sukodadi Kabupaten Lamongan pada bulan Oktober‒Desember 2019. Sampel penelitian adalah 104 lansia kelompok prolanis secara purposive sampling. Instrumen penelitian menggunakan kuesioner psychological distress dan Pittsburg Sleep Quality Index (PSQI). Analisis data dengan uji Spearman.Hasil: Sebagian besar 65,4% lansia mengalami tekanan psikologis ringan, dan 54,8% lansia memiliki kualitas tidur baik. Hasil uji Spearman rho p=0,004 dan r=0,282, berarti terdapat hubungan kondisi psikologis dengan kualitas tidur lansia penderita penyakit kronis, kekuatan korelasi lemah dan bersifat positif.Kesimpulan: Kondisi psikologis secara statistik berhubungan dengan kualitas tidur pada lansia penderita penyakit kronis pada kelompok prolanis.

Pendahuluan:Tugas perkembangan kemandirian anak pada usia toddlerdapat dilatih dengan toilet training. Faktanya pada anak prasekolah masih ada yang anak yang belum siap dan belum berhasil melakukan toilet training. Hasil studi pendahuluan salah satu TK di Lamongan menunjukkan sebagian kecil anak prasekolah masih mengompol dan memakai pampers saat malam hari. Penelitian ini bertujuan untuk menganalisis hubungan tingkat pengetahuan ibu dengan keberhasilan toilet trainingpada anak prasekolah. Metode:Penelitian cross sectionaldengan jumlah sampel 40 responden memakai teknik simple random sampling. Pengumpulan data menggunakan kuesioner tingkat pengetahuan ibu dan kuesioner keberhasilan anak dalam toilet training. Analisa data meliputi univariat dan uji fishers exact test(p value < 0.05). Hasil:Penelitian menyebutkanadanya hubungan antara tingkat pengetahuan ibu dengan keberhasilan toilet training pada anak prasekolah (p value = 0.013).Simpulan:Perlu adanya pendidikan kesehatan dari puskesmas dan dinas pendidikan tentang toilet training kepada orang tua untuk meningkatkan kesiapan dan keberhasilan toilet training.

Children’s physical, mental, social, and emotional growth and development are influenced by nutrition, health, and education. This factor can be identified by conducting early screening to see growth and development deviations in children. So interventions can be carried out as early as possible as an initial corrective action or deviations do not become more severe, and referrals are made as early as possible according to indications. Data on the coverage of health services for children under five in Lamongan Regency was 1,738 (92.3%) of 1,882 toddlers in 2019, while data in Pucuk Subdistrict contained 36 under-fives with less nutrition than 2,591 under-fives who were weighed aged 0-59 months (1.4%), 29 short toddlers out of 2,588. toddlers 0-59 months height measured (1.1%), and 68 underweight toddlers (2.6%). The target of the activity is to increase the knowledge and skills of cadres in carrying out the Stimulation of Early Detection and Intervention of Growth and Development (SDIDTK). The method is carried out in three stages, the socialization stage in the form of health education and training of cadres, the work stage in the form of mentoring during Integrated Healthcare Center (Posyandu), and the evaluation and recommendation stage. Cadres are very enthusiastic in following the material and are active during mentoring. The increase in knowledge was seen in the pre-test and post-test scores.

Introduction: Psychological well-being is an individual's feelings about everything from trauma to acceptance of life. Diabetes mellitus is a chronic disease that is a major problem in the world of health and a disease that has the most consequences on physical, psychological, and social. Every type 2 diabetes mellitus patient has a different psychological condition, some have high psychological well-being and some have low psychological well-being. This study aimed to analyze the relationship between patient factors and psychological well-being in type 2 diabetes mellitus patients at the Tikung Lamongan Health Center UPT. Methods: This research method is quantitative with a correlational research design. The sampling technique used consecutive sampling, samples were taken on March 24 - April 2, 2022 at the Tikung Lamongan Health Center UPT with a total of 57 respondents. The instruments used were the SPWB Ryff questionnaire (1995), demographic data, and religiosity questionnaire compiled by Kartika (2017), while the data analysis used the chi-square test from SPSS. Results: The results showed no relationship between patient factors based on age, gender, education, and psychological well-being in patients with type 2 diabetes mellitus because it had an Asymp. Sig. (2-sided) value > 0.05, while patient factors based on religiosity were related to psychological well-being because it had an Asymp. Sig. (2-sided) value of 0.000. Conclusions: This study is expected to increase information and knowledge about efforts to prevent and control type 2 diabetes mellitus so that the psychological well-being that is owned increases.
