Abstract

Kombinasi nikotinamida, vitamin B6, dan vitamin C sering digunakan dalam suplemen kesehatan. Kandungan ketiga senyawa dalam produk tersebut tergolong rendah, sehingga penentuan kadar mereka memerlukan teknik analisis yang tidak hanya sensitif tetapi juga mampu mengukur secara bersamaan. Salah satu teknik yang digunakan adalah kromatografi cair kinerja tinggi (KCKT). Namun, metode analisis yang sesuai masih terbatas. Penelitian ini bertujuan mengembangkan metode KCKT yang divalidasi untuk mengukur nikotinamida, vitamin B6, dan vitamin C, sekaligus mengaplikasikannya pada produk suplemen kesehatan. Prosedur penelitian memakai KCKT isokratik (Jazco) dengan deteksi UV pada panjang gelombang 272 nm. Fase diam berupa kolom C18 berukuran 125 mm x 4,6 mm, sementara fase gerak adalah campuran metanol, air, dan asam asetat glasial dengan perbandingan 15:85:1 dan kecepatan 1 mL/menit. Validasi metode menunjukkan hasil positif pada parameter linieritas (r = 0,999 untuk ketiga senyawa), akurasi (perolehan krmbali 99,05–100,80%), presisi (nilai %RSD ≤ 2%), selektivitas dengan daya pemisahan minimal 1,5, serta sensitivitas dengan batas deteksi (LOD) dan batas kuantifikasi (LOQ) masing-masing: nikotinamida (LOD 0,554 µg/mL; LOQ 1,846 µg/mL), vitamin B6 (LOD 0,068 µg/mL; LOQ 0,227 µg/mL), dan vitamin C (LOD 0,602 µg/mL; LOQ 2,006 µg/mL). Metode ini berhasil diterapkan untuk mengukur kandungan ketiga zat tersebut dalam tiga merek suplemen kesehatan.

Abstract

This systematic review synthesizes empirical evidence from 2015-2025 on the impacts of Climate-Smart Agriculture (CSA) adoption on farm performance. While CSA is promoted to raise productivity, strengthen resilience, and reduce emissions at the farm level, empirical findings remain fragmented and performance indicators are not yet standardized. This review systematically assesses effects during 2015-2025 on a core set of farm-level indicators yield (t ha⁻¹), cost (USD PPP ha⁻¹), margin/return on investment (ROI), income volatility, resilience, and environmental outcomes distinguishing single practices from bundled packages in the context of Indonesia and the broader ASEAN region. We searched Scopus, Web of Science, ScienceDirect, SpringerLink, and Google Scholar (2015-2025), normalized data to common units (t ha⁻¹, USD PPP ha⁻¹, CO₂e ha⁻¹), and conducted an analytical-comparative synthesis. Water-efficiency practices (e.g., alternate wetting and drying/AWD) generally maintained or increased yields, lowered water/energy costs, and curtailed CH₄ emissions. Multi-season field studies reported ~21-73% reductions in CH₄ and ~26-29% declines in global warming potential (GWP), contingent on adequate nitrogen management. Conservation agriculture improved soil health and medium-term profitability. Moreover, bundled practice packages (e.g., water-nitrogen-advisory) more consistently delivered multidimensional benefits than single practices. Heterogeneity is driven primarily by agroecology, asset and service access, and commodity (predominantly rice), warranting caution when generalizing to non-rice systems. Overall, evidence from 2015-2025 supports scaling CSA packages in tandem with lightweight measurement, reporting, and verification (MRV) based on standardized farmer-level indicators to ensure that technical gains translate into measurable economic and environmental benefits.

Abstract

Anemia pada ibu hamil adalah kondisi ketika kadar hemoglobin <11 g/dL, yang dapat meningkatkan risiko komplikasi seperti prematuritas, berat bayi lahir rendah, dan keguguran. Penyebab utama adalah defisiensi zat besi akibat asupan gizi yang tidak seimbang dan rendahnya kepatuhan konsumsi tablet tambah darah. Tujuan: Menganalisis hubungan antara tingkat pengetahuan gizi pada ibu hamil dengan kejadian anemia. Metode: Penelitian observasional analitik dengan rancangan cross-sectional pada 44 ibu hamil trimester III yang dipilih menggunakan consecutive sampling. Pengukuran kadar hemoglobin dilakukan menggunakan alat digital HemoCue Hb 201+ dengan kalibrasi harian, sedangkan tingkat pengetahuan dinilai menggunakan kuesioner terstandar yang telah melalui uji validitas isi oleh tiga pakar dan uji reliabilitas (Cronbach’s alpha = 0,84).Hasil: Mayoritas responden memiliki pengetahuan baik (68,2%) dan mengalami anemia (59,1%). Uji Chi-square menghasilkan p-value = 0,256 (p>0,05).Kesimpulan: Tidak terdapat hubungan signifikan antara pengetahuan gizi dan kejadian anemia pada ibu hamil di Puskesmas Leyangan. Namun demikian, hasil ini harus diinterpretasikan dengan hati-hati karena ukuran sampel kecil dan potensi selection bias.

Abstract

Geriatric patients are highly vulnerable to the use of Potentially Inappropriate Medications (PIMs) due to age-related physiological changes in pharmacokinetics and pharmacodynamics that may affect the body’s ability to process medications. Therefore, evaluation of medication use is essential to determine the safety of drugs administered to geriatric patients. This study aimed to describe the characteristics of geriatric patients receiving central nervous system (CNS) medications based on sex and disease profiles at the inpatient unit of RSUD Tugurejo Semarang from January to December 2022, to assess the patterns of CNS drug use in geriatric inpatients during the same period, and to evaluate the appropriateness of CNS medication use in geriatric patients in terms of drug appropriateness and patient appropriateness based on the 2023 Beers Criteria. This study employed a descriptive design with retrospective data collection, and purposive sampling was used as the sampling technique. The study subjects were geriatric inpatients who received CNS medications at RSUD Tugurejo Semarang from January to December 2022. The study sample consisted of hospitalized geriatric patients aged ≥65 years. The results showed that male patients accounted for 56% of the total 41 geriatric patients included in the study. The most common age group among geriatric patients receiving CNS medications was 65–69 years, accounting for 59%. The most frequently used CNS medication classified as “to be avoided” in geriatric patients was alprazolam (37%), while CNS medications with disease interactions were most commonly represented by donepezil, with three cases (100%). Evaluation of medication appropriateness revealed 45 cases (67%) of appropriate drug use and 63 cases (94%) of appropriate patient use.
