Abstract

Food commodities can actually be stored for a long term after harvesting, but there are some constraintsof decrease in the quality of the fruit because of several postharvest diseases caused by microorganismssuch as fungi, bacteria, and viruses. The most frequently postharvest diseases trigger found is a group ofpathogenic fungi. The results of identification of fungi causing disease in several types of fruitpostharvest which were performed by blotter test method and medium PDA showed that Colletotricumcapsici fungi was found in chili, Rhizoctonia solani in bananas and tomatoes, Amerosporium sp. inpapaya, Pythium sp. on bananas, Fusarium solani on mango, banana, and papaya, and Phomopsis sp. ontomatoes.Keywords: fungi, food commodity, identification, postharvest diseases

Abstract

Mangifera Sumatera bagian Tengah memiliki kemampuan unik dalam beradaptasi pada wilayah dengan curah hujan yang tinggi, sehingga berpotensi sebagai sumber plasma nutfah Sumatera. Secara morfologi genus Mangifera cukup sulit dibedakan karena tingginya plastisitas morfologi. Mangifera odorata diduga sebagai spesies hibrid dari M. indica dan M. foetida, sehingga diperlukan analisis untuk memperkuat status taksonomi M. odorata. Tujuan penelitian ini untuk merekonstruksi hubungan kekerabatan M. odorata dan kerabatnya berdasarkan gen rbcL. Rekostruksi menggunakan program PAUP* Versi 4.0b10 dengan metode maximum parsimony (MP). Kladogram dengan metode MP membentuk klad monofiletik dengan dua klad utama Mangifera. Klad pertama yaitu M. indica dan klad kedua terdiri dari M. foetida dan M. odorata. Kladogram mendukung asumsi bahwa M. odorata adalah hibrid dari M. foetida dan M. indica.

Abstract

Wild Mango from Sumatera is potentially new immunostimulant. It contains mangiferin, which is potentially become the immunostimulant candidate. This study aimed to prove the immunostimulatory effect of wild mango leaves extract on white rat peritoneum fluid induced by Staphylococcus aureus bacteria. The immunostimulatory effect was determined based on the activity and capacity of macrophage phagocytosis. This study used 54 male white rats about 130 g - 290 g. Based on the results,the highest phagocytosis activity of macrophage cells was found in ethanol extract of Mangga Hutan leaves dose 2 with a percentage of phagocytosis activity was 84%. The highest phagocytosis capacity of the macrophage cells was also found in ethanol extract of Mangga Hutan leaves dose 2 with an average phagocytic capacity of 171.67 from 50 active macrophages. Results of this study indicated that wild mango leaves from Sumatera has the potential immunostimulant activity. This indicates that the wild mango have the potential for therapeutic efficacy for the prevention of degenerative diseases caused by immune deficiencies.

Abstract

AbstrakMacang (Mangifera foetida) adalah jenis mangga kosmopolit dengan vigoritas yang kuat. Macang banyak ditemukan di perkarangan dan kebun dan bersifat semi liar. Penurunan luas lahan seperti deforestasi dapat mengakibatkan keanekaragaman kultivar macang juga mengalami penurunan secara cepat. Penelitian ini bertujuan untuk menganalisis dan merekonstruksi hubungan kekerabatan antar kultivar macang menggunakan sekuen gen rbcL. Sampel berasal dari koleksi hasil eksplorasi mangga Sumatera bagian Selatan, yaitu Provinsi Bengkulu, Lampung dan Sumatera Selatan. Ekstraksi DNA dilakukan dengan menggunakan metode CTAB yang dimodifikasi, kemudian DNA diamplifikasi dengan menggunakan primer spesifik rbcL forward dan reverse, dan dilakukan sekuensing serta analisis filogenetik. Rekontruksi pohon filogenetik menggunakan program PAUP* versi 4.0b10 dengan metode Maximum Parsimony (MP) dan Neighbor Joining (NJ). Kladogram dengan MP diperoleh dua klad, yaitu pada klad I terdiri dari kultivar Macang lonjong dan Macang lado, sedangkan klad II terdiri dari kultivar Macang bulat. Berdasarkan metode NJ, diperoleh Macang bulat memiliki jarak genetik lebih panjang sehingga dianggap sebagai individu yang lebih primitif daripada kultivar yang lain. Dengan demikian, dari penelitian ini diperoleh informasi dan bukti dari status taksonomi kultivar macang.Abstract Mangifera foetida is a species of cosmopolitan mango with strong vigor. Some M. foetida are found in some front houses and gardens and has a character of semi-wild in its cultivation. Decreases in land area, such as deforestation, can lead to a rapid decline in their diversity of cultivars. This study aimed to analyze and reconstructs the phylogenetic relationship among M. foetida cultivars using the rbcL gene sequences. Samples were collected from the exploration within the area of South Sumatra, such as Provinces of Bengkulu, Lampung and South Sumatra. The DNA extraction was carried out using the modified CTAB method, followed by DNA amplification using rbcL-specific primers, sequencing, and phylogenetic analysis. The phylogenetic trees were reconstructed using the PAUP* version 4.0b10 by using the method of Maximum Parsimony (MP) and Neighbor Joining (NJ). Cladogram of the MP tree showed two clades that the clad I consisted of M. foetida (Macang lonjong) and M. foetida (Macang lado) cultivars, whereas clad II consisted of M. foetida (Macang bulat) cultivar. The NJ tree showed that M. foetida (Macang bulat) has a longer genetic distance so it is considered as a more primitive cultivar than others. Therefore, information and evidences from the taxonomic status of the M. foetida cultivars were obtained from this study.

Abstract

Concrete is a common building material and is very vulnerable to cracking caused by unstable temperature/humidity. Concrete crack repair can be done by using microorganism substitution that can produce CaCO3 (calcite) compounds that can be used as an environmentally friendly method in improving structural formation and increasing the strength and durability of concrete, one of which is using ureolytic bacteria. This study aimed to isolate and characterize ureolytic bacteria isolates and then to assess the calcite precipitation potential of ureolytic bacteria isolates from landfills. The ureolytic bacterial isolates were grown on NB-U/Ca and tap water medium. Analysis of Calcite Structure using Fourier Transform Infra-Red (FTIR), and molecular identification using 16S rRNA gene sequences. Bacterial isolate SP. 48 were able to grow and produce calcite in both media, especially in tap water medium. FTIR results showed that the precipitates produced by bacterial isolates on both mediums had strong absorption peaks, which were detected to be calcite. Molecular identification using the 16S rRNA gene sequence showed that the isolate is Bacillus albus. B. albus is a proteolytic bacterium collected from landfills that was proven to be a calcite-producing bacterium, a new finding in this study. B. albus can grow and produce calcite in a tap water medium with low pH. This finding can be used as an alternative to overcome concrete cracks and increase the strength and durability of concrete. This bacterial isolate could be developed as a biocement candidate.

Abstract

Abstract Dysmenorrhea is an important clinical as well as social problem affecting more than 50% of menstruating women. Nanas bongsai (Ananas comosus var. microstachys L.) is commonly used as a medical plant, which local people believe of Riau Province Indonesia, as medicine to reduce pain while the menstruation period (dysmenorrhea). This study was aim to find histopathologic changes in the kidney and liver after being treated with nanas bongsai extract in the female white rat.  Design experimental of this research is complete randomized design with 5 treatments. Each treatment was composed of two control (zero control given with water, positive control given with mefenamic acid) and nanas bongsai extract with 3 different dosage serials. Histology preparations were made by paraffin method and Hematoxylin-Eosin staining. The results showed that given nanas bongsai extract with three serial dosages towards the kidney show a picnosis in the nucleus. However, this damage did not affect the glomerulus structure. While observation towards the liver shows some injury, namely hydropic degeneration, lipid degeneration, and necrosis. Both of these damaged less than 25%. As a result, this percentage did not affect the structure of the kidney and liver. The results of this study indicate that there is no damage to the kidneys and liver due to the use of nanas bongsai so it is safe to use in herbal medicine and can be developed as a dysmenorrhea drug.AbstrakDismenore merupakan masalah klinis dan sosial yang penting yang memengaruhi lebih dari 50% wanita menstruasi. Nanas bongsai (Ananas comosus var. microstachys L.) dipercayai oleh masyarakat Desa Muara lembu, Kabupaten Kuantan Singingi, Provinsi Riau sebagai obat untuk mengurangi nyeri saat haid (dismenore). Penelitian ini bertujuan untuk mengetahui perubahan histopatologi pada ginjal dan hati setelah diberi perlakuan ekstrak nanas bongsai pada tikus putih betina. Rancangan percobaan yang digunakan adalah rancangan acak lengkap dengan 5 perlakuan. Masing-masing perlakuan terdiri dari dua kontrol dan ekstrak nanas bongsai dengan 3 seri dosis yang berbeda. Preparat histologi dibuat dengan metode parafin dan pewarnaan Hematoxylin-Eosin. Hasil penelitian menunjukkan bahwa pemberian ekstrak nanas bongsai dengan dosis tiga seri terhadap ginjal menunjukkan picnosis pada nukleus. Namun, kerusakan ini tidak memengaruhi struktur glomerulus. Sedangkan pengamatan terhadap hati menunjukkan beberapa cedera, yaitu degenerasi hidropik, degenerasi lipid, dan nekrosis. Keduanya rusak kurang dari 25%. Akibatnya, persentase ini tidak memengaruhi struktur ginjal dan hati. Hasil penelitian ini menunjukkan bahwa tidak ada kerusakan pada ginjal dan hati akibat penggunaan Nanas bongsai sehingga aman digunakan dalam pengobatan herbal dan dapat dikembangkan sebagai obat dismenore.
