Abstract

This research was conducting to quantify the berberine concentration. Rapid method using 1H-NMR was used to determine berberine quantitative and qualitatively from the crude extract. Tali kuning was collected from Manokwari Papua Barat and powdered with hammer mill. Sonication was employed to extract using methanol at room temperature. 500 µg authentic berberine chloride were dissolved in 5.4 mL methanol-d4 (containing 84.4 µg anthracene). 1H-NMR spectra were recorded in methanol-d4 (99,9%) using JEOL JNM-ECX 500. Each sample was scanned for 100 using the following parameter 0.18 Hz/point, spectral width 14400 Hz, pulse with 4.0 US, relaxation delay 2 sc. Peak areas were used for qualitative analysis and integration of each peach were employed for quantitative analysis. The results demonstrated that 1H-NMR signal pattern of H-13 and H-8 recorded from Tali Kuning, and Amur corktree were well recorded, and in accordance to the berberine chloride standard. Using peak integration of H-13 and H-8, the berberine quantity in Tali kuning is 18.06 mg/g of dried powder, and 22.78 mg//gr for Amur corktree. Berberine percentage based on the weight of oven-dried-extracts was 8.34% (MC 7.54%) and 12.04% (11,54%) for Amur corktree and Tali kuning.

Abstract

Secara umum, permasalahan yang dihadapi oleh guru SD dalam mengenal lagu baru adalah kesalahan dalam menyanyikan lagu sesuai partitur. Penyebabnya adalahrendahnya tingkat kemampuan guru SD dalam membaca notasi balok. Keterbatasan inilah yang menuntut guru SD untuk meningkatkan kemampuannya secara berkelanjutan. Dalam mempelajari notasi balok dibutuhkan media yang tepat, yaitu menggunakan media Encore. Diharapkan melalui media pembelajaran Encore ini, kemampuan guru SD dalam menbaca notasi balok akan meningkat.

Abstract

Penelitian ini bertujuan untuk mengetahui jumlah, jenis limbah, volume dan komposisinya dari beberapa stand kayu di Distrik Manokwari Barat, Kabupaten Manokwari. Dalam pelaksanaan penelitian ini menggunakan metode deskriptif dan teknik survei melalui wawancara pada tiga stand kayu yaitu Farrel Jaya, Hati Murni 2 dan Hati Murni 1. Hasil penelitian memperlihatkan bahwa terdapat tiga jenis bahan baku kayu gergajian yaitu Merbau (Intsia sp.), Matoa (Pometia sp.) dan Rimba Campuran. Jenis limbah yang dihasilkan berupa sebetan, serbuk dan tatal. Dari sortimen olahan balok dan papan sebanyak 30 m³, dihasilkan limbah sebanyak 46,73 %/m³ dengan rata-rata jenis limbah sebetan sebanyak 7,47 %/m³, serbuk 6,80 %/ m³ dan tatal 32,47 %/m³. Proses pengolahan lanjutan dari limbah masih belum terlihat dimana semua limbah biasanya hanya dibakar.

Abstract

Introduction: Intracranial foreign bodies are usually caused by trauma that penetrates the cranium. Gunshot wounds are the most common cause, while non-missile intracranial penetration is rare. The patient’s clinical condition highly depends on the mechanism, anatomical location of the lesion, and related injuries. Possible complications include intracerebral hemorrhage, contusion, major injury on the vascular, and meningitis. In this article, we report case of intracerebral nail extraction from a patient with right cerebral foreign body. Case presentation: A 22-year-old man with a history of unspecified schizophrenia reported with reduced awareness accompanied by weakness of his left limb. During a head CT scan of the head, there are several tubular foreign bodies in the right cerebral. Craniotomy for foreign body extraction and drainage of the cerebral abscess is immediately performed. Four days after surgery, the patient had increased awareness, although there was no significant improvement in motor strength. One month after discharged from hospital there was slight improvement in motor strength. Conclusion: Extraction of foreign bodies by a surgical procedure is mandatory and should be performed thoroughly. The administration of antibiotics, anticonvulsants, physiotherapy, and psychiatric follow-up should be added to the treatment of this patient.
