Abstract

Bread has been chosen as an alternative food because of its availability. In Indonesia, consumptionof breads is increased due to the change of diet pattern into packed and ready-made meals. Therefore, it isimportant to raise the awareness of bakery products quality. The purpose of this study was to detect andidentify the microbial contaminant in bakery products in Yogyakarta City, Indonesia. Bacterial coloniesfrom expired bakery products were isolated into pure isolate then confirmed by API Staph and PolymeraseChain Reaction (PCR) method. The results showed there were five kinds of gram-positive bacteria. Isolatedbacteria identified by API were Bacillus cereus (52.8%), Bacillus subtilis (97.7%), Staphylococcus aureus (97.7%),Staphylococcus epidermidis (97,9%) and Staphylococcus saprophyticus (72,2% and 61,8%).

Abstract

Kesambi (Schleichera oleosa L.) is one of ligneous tree that is abundantly found in Timor island, East Nusa Tenggara Province of Indonesia. Kesambi is known as an important component in local smoked meat home industry. Kesambi is also a promising natural source for the production of biodiesel. Application of three lipolytic fungi that is isolated from kesambi seeds and the use kesambi seeds flour as medium for indigenous lipase synthesis (Aspergillus niger M1407 lipase) by Solid-State Fermentation (SSF) showed good result for lipase and biodiesel industry development. This study aimed to characterize biodiesel synthesis using indigenous lipase from kesambi seeds. Experiments were carried out through five stages namely: oil extraction from kesambi seeds, purification of kesambi oil (degumming), extraction of A. niger M1407 lipase, trans-esterification and esterification activity of A. niger M1407 lipase assay and characterization of biodiesel. Biodiesel synthesis using A. niger M1407 lipase through esterification reaction produced biodiesel with an average acid number of 0.33 and 0.40 mg/g, water content 9.52 % and 10.47 % and density 0.7 g/mL. Biodiesel obtained from kesambi oil has lower acid numbers and densities but higher water content compared to Indonesian National Standard (SNI) value. Optimalization of the biodiesel kesambi oil synthesis could be done through adjusting ethanol and kesambi oil ratio and also by reducing water as a by-product of esterification reaction

Abstract

Orangutan (Pongo pygmaeus morio) merupakan satwa langka yang harus dikonservasi melalui pelestarian Taman Nasional Kutai (TNK). Studi karakteristik sarang orangutan merupakan bagian dari upaya pelestarian. Metode yang digunakan dalam penelitian ini adalah menggunakan jalur transek dengan menghitung sarang orangutan serta mencatat karakteristik sarang orangutan yang meliputi kelas sarang, posisi sarang, tinggi sarang, tinggi pohon, diameter pohon dan jenis pohon sarang. Pada lokasi penelitian ditemukan sebanyak 173 sarang orangutan yang terdiri dari 84 sarang di resort Sangatta dan 89 sarang di resort Sangkima. Jenis sarang didominasi oleh kelas sarang C dan D dengan posisi sarang sebagian besar terdapat pada ujung dahan (UD) di resort Sangatta, posisi sarang terbanyak ada pada ujung dahan (UD) dan pucuk pohon (PP) di resort Sangkima. Rata-rata tinggi sarang orangutan adalah 12,2 - 40,2 m, diameter pohon 17,4 - 110 cm, dan tinggi pohon 12,2 - 40,2 m di resort Sangatta. Pada resort Sangkima rata-rata tinggi sarang orangutan adalah 10,2 - 24,2 m dengan diameter pohon 20 - 109,4 cm dan rata-rata tinggi pohon 14-28,6 m. Karakteristik sarang orangutan menjadi indikator kondisi habitat orangutan yang ada di TNK

Abstract

Bakteri Asam Laktat (BAL) yang terkandung dalam susu fermentasi akan menghasilkan asam-asam organik, hidrogen peroksida, diasetil, asetaldehid, asetoin, reutinin, reuterisiklin dan bakteriosin, dapat sebagai anti-Candida. Spesies Candida non-albicans seperti C. tropicalis dan C. glabrata sebagai penyebab kandidiasis oral cenderung meningkat. Tujuan penelitian ini mengetahui aktivitas antifungi susu fermentasi komersial pada Candida non-albicans dan viabilitas bakteri asam laktat di dalam susu fermentasi komersial. Aktivitas antifungi pada Candida non-albicans dilakukan dengan metode difusi sumuran. Viabilitas bakteri asam laktat dihitung berdasarkan jumlah bakteri asam laktat sebagai jumlah bakteri total (Total Plate Count). Hasil penelitian menunjukkan bahwa susu fermentasi komersial lebih mampu menghambat C. tropicalis dibandingkan C. glabrata. Viabilitas bakteri asam laktat dalam susu fermentasi komersial 107-1010 CFU/mL.

Abstract

Lipstick is one kind of cosmetics which is used as lips colorant to increase self-confidence. Nowadays, lipsticks from natural source is popular to reduce the negative impact of chemical compound or synthetics colorant in lipstick intensively for health. Super red dragon fruit is one kind of natural ingredients which can be used as colorant for lipstick. Moreover, this fruit is rich of antioxidant and antibacterial component that is good for skin health. In this research, extract of super red dragon fruit flesh was added in the lipstick during preparation with variation of concentration 0, 10, 20, 30 and 40%. Antioxidant analysis resulted the IC50 value in 81.55% indicating the strong antioxidant properties. Furthermore, the concentration of dragon fruit extract 40% was able to inhibit the growth of Staphylococcus aureus bacteria.

Abstract

Malaria is known as an endemic disease that often causes death in Indonesia, especially in Papua. The malaria cases control in Papua has not been carried on based on data studies, therefore bionomic of Anopheles sp is important to be studied. Bionomics data are consisted of breeding places, resting places and feeding habits are from direct observation. Interviews and questionnaires were conducted to gain information about respondent behavior. Descriptive and qualitative data were then analyzed. The breeding places of Anopheles sp. were mostly found in swampy areas. Based on the feeding habit, the feeding activity of Anopheles sp. inside the house has only one biting peak at 23.00-02.00 WIT, while outside the house, biting peaks occurred at 21.00-22.00 WIT and 00.00-01.00 WIT. Resting place data shown that Anopheles sp. mostly found in piles of clothes and shoe racks. Recorded factors that affect mosquitos bionomics are temperature, humidity, salinity, pH, community behavior, and the presence of livestock. Environmental factors (temperature, humidity, salinity, and pH), habitual behavior of host (3M action, the habit of using insect repellent, mosquito repellent, and mosquito nets), the presence of livestock, and the type of bait blood type affect mosquito activity
