Abstract

ABSTRACT Processing of coconut fruit in Gunung Megang Village, Gunung Megang Muaraenim District aims to produce pure oil or Virgin Coconut Oil (VCO) which is the result of processed fresh coconut fruit by fermentation without going through a heating process, no additional chemicals, dyes, and preservatives so that it can survive. as vegetable oil. The method in this research is experimental. The results showed that making VCO using 2 coconuts produced 100 ml of VCO while VCO using 3 coconuts produced 300 ml of pure oil. It is hoped that the use of coconut fruit is not only sold in the form of unprocessed fruit but coconut fruit can be processed into pure oil or Virgin Coconut Oil and can be developed more broadly through village entrepreneurship programs so as to increase people's income, especially the people of Gunung Megang Village. Keywords: virgin coconut oil, fermentation, gunung megang village

Abstract

Penelitian non-experimental dapat dilakukan diberbagai bidang salah satunya bidang kesehatan. Dalam bidang kesehatan Randomized Controlled Trials (RCT) tidak dapat dilakukan karena berhubungan dengan nyawa manusia. Kovariat pada penelitian non-experimental biasanya tidak seimbang antara kelompok treatment dan kontrol. Ketidakseimbangan ini menyebabkan estimasi efek perlakuan menjadi bias. Selain itu, adanya variabel confounding juga mengakibatkan estimasi efek perlakuan bias. Metode yang sesuai untuk mengatasi efek perlakuan yang bias adalah metode  Propensity Score (PS). Salah satu metode yang dikembangkan dari propensity score adalah metode Propensity Score Matching (PSM). Pada penelitian ini, peneliti akan membandingkan performa metode propensity score matching-support vector machine dan metode propensity score matching-regresi logistik biner pada kasus infeksi oportunistik HIV/AIDS. Variabel confounding yang digunakan dalam penelitian ini adalah variabel infeksi oportunistik. Data yang digunakan dalam penelitian ini adalah data pasien HIV/AIDS yang di rawat di Puskesmas Grati, Kabupaten Pasuruan pada tahun 2016. Hasil analisis propensity score matching-support vector machine dan metode propensity score matching-regresi logistik biner menunjukkan bahwa variabel pemberian terapi ARV berpengaruh secara signifikan terhadap infeksi oportunistik pada pasien HIV/AIDS. Jika dilihat seberapa bias yang dapat tereduksi, propensity score matching-regresi logistik biner mampu mereduksi bias lebih besar dibanding metode propensity score matching-regresi logistik biner yaitu sebesar 60,25%. Namun, metode propensity score matching-support vector machine dapat menghasilkan nilai bias (setelah matching) yang lebih kecil dibanding metode propensity score matching-regresi logistik biner yaitu sebesar 0,044.

Abstract

This study aims to determine the diversity of butterflies in protected forest of Pulau Panas Village, Tanjung Sakti Pumi, Lahat, South Sumatra. The research was conducted in October – November 2020. The research sites were three different types of habitat, namely primary forest, riverbanks, and transitional or ecotone area of forests and plantations. Data collection uses exploration or roaming techniques following a 300-meter-long path with a width of 2 m to the right and 2 m to left in each habitat type using insect nets. The results obtained 61 species of butterflies (Lepidoptera: Rhopalocera) belonging to 5 families (8 species of Papilionidae, 11 species of Pieridae, 33 species of Nymphalidae, 3 species of Hesperiidae and 6 species of Lycaenidae). The highest diversity (Shannon index) is in primary forest habitat with H'= 3.67; followed by transitiononal forest and plantation areas with H' = 3.62, while the lowest diversity index is riverbanks with H'= 3.24. The evennes index of the species is almost the same (E>0.9). The highest species richness was found in primary forest (Dmg: 9.75). Protected butterfly species (according to the Decree of Ministry of Environment and Forestry No. 106 year 2018) found in this study is Troides helena.Keywords: diversity, lepidoptera, protected forest, rhopalocera, south sumatra

Abstract

Basal stem rot of oil palm caused by Ganoderma boninense is difficult to be controlled due to abundance of inoculum sources in the field. This study was aimed to determined effects of taro plants viz. Belitung taro (Xanthosoma sagittifolium), Bogor taro (Colocasia esculenta), and Japanese taro (Colocasia esculenta var. antiquorum) on decay of G. boninense inocula. Pathogen inocula as rubber wood block (RWB) colonized by G. boninense was attached with main roots of oil palm seedling and buried into soil of oil palm seedling (monoculture), mixed planting of oil palm and taro plants, or of taro plants monoculture. Burying of pathogen inocula for 3 and 6 months on taro plant resulted in 2.1 times higher decay of RWB compared than oil palm monoculture. Increasing of decay also exhibited on mixed cropping system, but it was slightly lower than on oil palm monoculture. This result suggesting the benefit of taro plants either planted under monoculture or mixed cropping to fasten decomposition of infected wood debris as an inoculum source of G. boninense.

Abstract

Indonesia has the potential for abundant natural resources including medicinal plants that have anticancer activity. The aim of this study is to determine the anticancer potential of three Sansevieria plant species extracts using the Brine Shrimp Lethality Test Method. This research is an experimental research method by invitro. Anticancer potency test using the BSLT method on extracts of three species of  lidah mertua leaves consisting of Sansevieria trifasciata, Sansevieria tiger green, and Sansevieria Zeylanica. The results showed that the three species of Sansevieria have potential as anticancer, but the most potential as an anticancer is Sansevieria tiger Hijau because it is very toxic with an LC50 value of 29.646 ppm.

Abstract

Basal stem rot (BSR)  caused by white decay fungus, Ganoderma boninense is known to cause significant losses in oil palm plantation in Southeast Asia. This study determined the effect of oil palm mixed planting with rhizomatous plants, galangal (Alpinia galangal), Java curcumin (Curcuma longa), or ginger (Zingiber officinale) on initial infection of BSR. Plants were inoculated by attachment of rubber wood block colonized with G. boninense to the main roots. Infection was measured as length of root necrosis and confirmed by culturing on Ganoderma selective medium. Infection was also assessed by total activity of ligninase as measured by RBBR decolorization. The results showed that G. boninense infection at 1-month-post inoculation was lower on mixed planting with all rhizomatous plants, and the suppression of infection was still occured in mixed planting with galangal. Total activity of ligninase on oil palm roots was delayed on mixed planting compared to that of higher activity on single planting at 1-month-post inoculation. This result highlights benefit of mixed planting of oil palm with  rhizomatous plants in delaying initial infection of BSR patogen.

Abstract

Background: The immune system is closely related to leukocytes. Leukocytes are part of the immune system which have an important role in every disease-causing agent. One of the efforts that can be made to increase the immune response is to provide an immunomodulator, a substance that can improve the immune system by means of stimulation (immunostimulants). Black cumin is able to stimulate bone marrow and immune cells and is able to protect normal cells from damage by disease agents, an increase in the total number of blood cells and their differentiation. Objectives: The purpose of this study was to determine the effect of giving black cumin oil extract on leukocyte levels in male mice. Methods: This type of research is experimental, to see the levels of leukocytes, after being treated with doses of 150 mg/kgBB, 300 mg/kgBB and 600 mg/kgBB for 21 days. The data obtained were then analyzed statistically using the ANOVA test. Result: The results obtained by the total number of leukocytes on day 7, day 14 and 21 showed a significant difference (p <0.05) for each treatment group. The use of black seed oil extract is very effective for boosting the immune system or immunostimulating. Conclusion: The benefit of this research is that it can provide information to the public that black cumin oil extract can be used as an alternative in increasing the body's immune system. Keywords: immunostimulants, black cumin, male mice
