Evaluasi Mutu Lada Putih Bubuk Yang Diperdagangkan Di Pasar Tradisional Dan Modern Di Bogor Dan Jakarta

Abstract

<p>Lada putih bubuk mempunyai sifat sangat higroskopis, sehingga mudah mengalami kerusakan, baik fisik, kimia ataupun mikrobiologis. Tujuan dari penelitian adalah menentukan mutu lada putih bubuk, baik secara fisik, kimia dan mikrobiologi dari pasar tradisional dan modern di wilayah Bogor dan Jakarta serta mendapatkan informasi awal/indikasi adanya pencampuran bahan lain pada lada putih bubuk. Metodologi penelitian terdiri atas beberapa tahapan, yaitu metode pengambilan sampel dilakukan secara acak sederhana (<em>simple random sampling</em>), dari pasar tradisional yang dijual secara curah, dan pasar modern yang dikemas dalam botol plastik, masing-masing 3 lokasi dan 3 ulangan. Untuk masing-masing sampel yang diambil dari pasar tradisional dan modern adalah 300 g. Pengujian fisiko-kimia sesuai dengan metode yang dikeluarkan oleh IPC (<em>International Pepper Community</em>), yaitu kadar air, abu, abu tak larut asam, minyak atsiri, piperin dan logam timbal (Pb). Untuk uji mikrobiologis terdiri dari TPC (<em>Total Plate Count</em>), kapang, jamur, <em>Salmonella</em> dan <em>Escheria coli</em>. Selain itu, dilakukanan analisis SEM (<em>Scanning Electrone Microscope</em>) untuk melihat profil morfologi permukaan. Hasil penelitian menunjukkan bahwa untuk kadar air, abu, minyak atsiri masih memenuhi kriteria SNI 01 3717 1995, kecuali kadar abu yang tidak larut asam dan kadar piperin. Cemaran mikrobiologi (TPC, kapang dan jamur) memenuhi kriteria, kecuali <em>E. coli</em> dan jamur pada sampel dari pasar tradisional Bogor. <em>Salmonella</em> memenuhi kriteria SNI untuk semua sampel, yaitu negatif. Cemaran logam berat (Pb) masih memenuhi ketentuan kriteria SNI. Deteksi pencampuran lada putih bubuk dengan bahan lain menggunakan metode kombinasi sifat fisiko-kimia dan SEM baru bisa mendeteksi adanya indikasi pencampuran, dan belum bisa menentukan jenis bahan percampurnya.</p><p> </p><p><strong>Evaluation Of Quality of White Pepper Powder on Trade in Traditional and Modern Markets in Bogor and Jakarta.</strong></p><p>White pepper powder has very hygroscopic properties, so it is easily damaged, physically, chemically, or microbiologically. The purpose of this study was to determine the quality of white pepper powder, physically, chemically, and microbiologically from the traditional and modern markets of Bogor and Jakarta and to obtain information of mixing white pepper powder using other ingredients. The research methodology consists of several stages, namely sampling from traditional markets that are sold in bulk, and modern markets, which are packaged in plastic bottles; the sample has taken from 3 locations and 3 replications. For each sample taken from traditional and modern markets was 300 g. The physico-chemical tested according to the methods issued by the IPC, especially for moisture, ash content, acid insoluble ash, essential oil, piperine and timbal (Pb). The microbiological was tested, including TPC, mold, fungus, <em>Salmonella</em> and <em>Escheria coli</em>. In addition, an SEM analysis was performed to see the surface morphology profile. The results showed that moisture, ash content, ash insoluble in acid, volatile oil still meets the criteria of Indonesian National Standard, except for ash insoluble in acid and piperine content. Microbiological contamination fulfilled SNI criteria except <em>E. coli </em>and mold in samples from PT Bogor. Salmonella was fulfilled SNI criteria for all samples, which are given negative. Heavy metal (Pb) still fulfils the requirement in SNI criteria. Detection of mixing white pepper powder with other ingredients using a combination of physico-chemical properties and SEM can detect the indication of mixing and has not been able to determine the type of mixing material.</p>

Efektifitas Kombinasi Kompres Jahe dan Senam Rematik untuk mengurangi Intensitas Nyeri pada Rheumatoid Arthritis

“…Stoilova (2007) mengatakan beberapa komponen jahe, seperti gingerol, shogaol dan zingeron memberikan efek farmakologi dan fisiologi seperti antioksidan, anti inflamasi, analgesic, antikarsinogenik, non-toksik dan nonmutagenik. 7 Selain terapi modalitas dengan kompes jahe terapi modalitas berikutnya adalah senam rematik. Menurut Arthritis Care and Research senam dapat menstimulasi meningkatnya pelepasan hormon endorphin.…”

Antibacterial Activity of Metanol Extract and n-Butanol Fraction of Euphorbia milii Leaves Against Staphylococcus aureus

“…Pengambilan sampel daun dari pekarangan rumah dilakukan pada pagi hari karena kandungan senyawa berkhasiat yang ada pada tumbuhan berada dalam keadaan maksimal di pagi hari (Hernani, 2012). Sampel penelitian telah dipastikan sebagai tanaman Euphorbia milii berdasarkan hasil determinasi dengan nomor 20/UN18/.7/LBL/2022.…”

Acceptability and Antioxidant Activities of Jelly Drink Ginger (Zingiber officinale R.), Curcuma (Curcuma xanthorriza R.) and Turmeric (Curcuma longa L.) Extract as A Healthy Drink Alternative for People with Hypercholesterolemia

“…Curcuma contains 6-10% essential oil, while the essential oil content of ginger and turmeric is 3.5% [9]- [11]. Essential oils are volatile components that determine the characteristics of spices, especially aroma [12]. The content of essential oils in curcuma extract is more than the other main ingredients, so the aroma of ginger, curcuma, and turmeric jelly drinks is dominated by the sharp aroma of curcuma, while the aroma of ginger and turmeric is masked by the aroma of curcuma which causes the evaluation of the aroma of jelly drink is not much different.…”
