Abstract

Pada penelitian ini telah dipelajari sintesis mikrokapsul minyak jeruk nipis (Citrus aurantifolia) dan immobilisasinya pada sampel kain kapas. Sintesis mikrokapsul dilakukan dengan metode polimerisasi in-situ menggunakan bahan kulit (shell) melamin formaldehid. Immobilisasi mikrokapsul pada kain kapas dilakukan dengan metode pad-dry dengan menggunakan binderpoliakrilat dan crosslinking agent N-methylol dihydroxyethylene urea. Sebagai bahan pembanding,metode immobilisasi yang sama dilakukan pula pada mikrokapsul minyak jeruk nipis berbasis kulit etil selulosa. Hasil penelitian menunjukkan bahwa mikrokapsul hasil sintesis terkarakterisasi mempunyai bentuk sperik dengan ukuran partikel 0,44 – 2,10 μm. Immobilisasi mikrokapsul berbasis melamin formaldehid memperlihatkan hasil optimum menggunakan binder poliakrilat, sedangkan mikrokapsul berbasis etilselulosa memperlihatkan hasil optimummenggunakan crosslinking agent N-methylol dihydroxyethylene urea.Kedua sampel kain dengan teknik immobilisasi optimummemperlihatkan ketahanan terhadap pencucian cukup baik hingga setara 5 kali pencucian rumah tangga.

Abstract

Dysoxylum merupakan salah satu genus yang memiliki metabolit sekunder dan aktivitas yang beragam, salah satu aktivitas yang menarik adalah mampu bertindak sebagai agen P-gp pada sel kanker payudara MCF-7. Kulit batang D.alliaceum dimaserasi berturut–turut dengan n-heksana, etil asetat dan metanol. Ekstrak n-heksan dipisahkan dan dimurnikan dengan berbagai teknik kromatografi dipandu dengan analisis kromatografi lapis tipis diperoleh dua senyawa stigmast-5-en-3β-ol (1), stigmasterol (2). Struktur kimia senyawa tersebut telah ditetapkan berdasarkan intrepretasi data-data spektroskopi dan dibandingkan dengan data spektra dari penelitian sebelumnya. Semua isolat senyawa dievaluasi aktivitas sitotoksiknya terhadap sel kanker payudara MCF-7. Senyawa 1 dan 2 dirujuk dari literatur menunjukkan aktivitas kuat dengan IC50 8,65 μg/mL.

Abstract

Plumbago zeylanica (Ki Encok) merupakan salah satu tumbuhan obat multifungsi yang banyak ditemukan di Indonesia. Daun dan akarnya berkhasiat sebagai obat pada berbagai penyakit termasuk anti jamur dan anti bakteri. Penelitian ini dilakukan untuk mengetahui senyawa bioaktif antibakteri yang dapat digunakan untuk mengobati penyakit gigi dan mulut. Dari hasil pemisahan dan pemurnann fraksi aktif, tiga senyawa telah berhasil diisolasi dari ekstrak n-heksana dan etilasetat daun Ki Encok (Plumbago zeylamica), yaitu 3β-galaktosasitosterol (1), epi-isoshinanolon (2), dan metil 2,4-dihidroksibenzoat (3). Ketiga senyawa tersebut telah diuji aktivitasnya terhadap bakteri untuk penyakit mulut dan gigi yaitu Streptococcus mutan dan Streptococcus sanguinis. Hasilnya, diameter zona hambat dari senyawa 1, 2, dan 3 terhadap bakteri S. Sanguinis berturut-turut sebesar 12,0; 10,3; dan 12,0 mm, sedangkan terhadap bakteri S. Mutans berturut-turut sebesar 13,3; 11,7; dan 13,5 mm.

Abstract

Spons pencuci piring 200.000 kali lebih kotor dibanding dudukan toilet. Berbagai bakteri penyebab penyakit seperti Eschericia coli, Pseudomonas dan Staphylococcus, berkembang biak di permukaan yang basah. Selain itu, 500 ribu bakteri hidup di dalam saluran pembuangan bak cuci piring. Jika spons dalam kondisi tidak kering (lembab karena direndam), maka akan menjadi markas semua bakteri. Penelitian ini bertujuan untuk menentukan populasi bakteri yang terdapat pada spons cuci piring yang basah. Identifikasi dilakukan dengan metoda molekular berbasis DNA yaitu teknik PCR-RFLP gen 16s rDNA. Metoda PCR-RFLP merupakan genetik fingerprinting yang akurat, cepat dan sederhana. Koloni bakteri yang ditumbuhkan dari spons pencuci piring di lisis dan digunakan sebagai templat untuk PCR. Hasil PCR gen 16s rDNA yang berukuran 1400 pb, dipotong dengan enzim restriksi, Hinf1. Hasil penelitian menunjukkan terdapat empat pola pemotongan yang berbeda-beda. Pola yang berbeda ini menunjukkan terdapat empat populasi yang berbeda hidup pada spons basah. Kami mengidentifikasi bahwa salah satu mikroba yang tumbuh adalah E. coli yang merupakan bakteri patogen.

Abstract

The paper reports the antioxidant activity of a non-volatile fraction of lime processing byproducts from the lime syrup home industry. The activity was measured by spectrophotometry to obtain the 50% inhibition concentration (IC50) using the 2,2- diphenyl-1-picrylhydrazyl (DPPH) method. The sample was extracted by the maceration method with n-hexane, ethyl-acetate, and ethyl-ethanol. The IC50 values of 681 ppm, 458 ppm, and 2,775 ppm were n-hexane, ethyl-acetate, and ethyl-ethanol. The experiments concluded that the ethyl-acetate extract provides the best inhibition value to scavenge free-radicals DPPH. The HPLC and mass spectroscopy were measured to find out the content and group of active compounds. The significant compounds consisted of naringin, poncirin, or neoponcirin, which are known as antioxidant substances. The result shows the potential application of the lime by-products, its volatile fraction, and the nonvolatile fraction, which is the production residue of lime peel. This work can be applied as an alternative to zero-waste lime production, which may benefit the industry and the environment.

Abstract

Introduction: The selection of birth attendants is one of the reproductive rights of individuals in determining where to give birth and who will assist in childbirth. Many factors influence the selection of birth attendants, including maternal knowledge, family roles, and BPJS card ownership. In the Cimanggu Health Center in 2021 48,7% of mothers were assisted by midwives, while 50,3% of mothers who gave birth were assisted by traditional birth attendants. The purpose of the study was to determine the relationship between knowledge, family roles, and health insurance ownership with the selection of birth attendants for pregnant women in Batuhideung Village, Cimanggu District, Pandeglang Banten in 2022.  Methods: The research method used was quantitative analysis using a cross-sectional approach using primary data, the number of samples was as much as 52 third-trimester pregnant women, total sampling technique, data analysis using Chi-Square test.    Result: The results of the univariate analysis revealed that the selection of birth attendants for pregnant women was mostly by health workers (midwives) 63,5%; with good knowledge of 55,8%; the role of the family supporting 71,2% and the ownership of BPJS Health was 65,4%. Based on the results of the chi-square test, there was a significant relationship between knowledge (p = 0,000); family roles (p = 0,011); and BPJS Health ownership (p = 0,000) with the selection of birth attendants for pregnant women.  Discussion: The conclusion of the study there is a significant relationship between knowledge, family roles, and ownership of BPJS Health with the selection of birth attendants for pregnant women. It is hoped that mothers and families can provide mutual support in choosing delivery assistance assisted by health workers, besides having a BPJS card so that mothers and families feel calm during childbirth because they get cost waivers.
