Abstract

Eceng gondok (Eichornia crassipes (Mart.) Solm) merupakan gulma perairan yang mengganggu ekosistem. Eceng gondok mengandung protein dan serat kasar yang tinggi. Kandungan serat kasar sulit dicerna, oleh karena itu, eceng gondok perlu diolah menjadi pakan ternak rendah serat kasar dengan cara fermentasi. Tujuan penelitian ini untuk mendeskripsikan kualitas hasil fermentasi eceng gondok pada berbagai lama waktu fermentasi dan konsentrasi bioaktivator. Jenis penelitian yang digunakan adalah eksperimental dengan 2 perlakuan yaitu konsentrasi bioaktivator dan lama fermentasi. Variasi konsentrasi ragi tempe sebagai bioaktivator meliputi 0 g/kg (V0), 14 g/kg (V1), 17,5 g/kg (V23), 21 g/kg (V3) dan 24,5 g/kg (V4). Variasi lama fermentasi yaitu 5 hari (L5) dan 10 hari (L10). Selanjutnya, proses fermentasi untuk setiap perlakuan adalah 10 kg Eceng gondok dengan 5 kali ulangan keseluruhan sampela berjumlah 50. Parameter yang diukur meliputi kadar protein, serat kasar dan kandungan energi, serta struktur fisik. Hasil analisis menggunakan Anava dua arah menunjukkan bahwa perlakuan V1L5 (14 g/kg dengan waktu fermentasi 5 hari) menghasilkan kandungan protein kasar 11,09%, kadar serat kasar 21,16% serta kandungan energi 1064,27 Kcal/kg menunjukkan kualitas terbaik. Hasil fermentasi eceng gondok secara fisik berstruktur remahan, berwarna coklat kehitaman, dan berbau khas tempe. Berdasarkan hasil tersebut disarankan untuk mengolah eceng gondok menjadi pakan ternak dengan melakukan fermentasi menggunakan ragi tempe 14g/kg berat basah eceng gondok selama 5 hariWater hyacinth (Eichornia crassipes (Mart.) Solm) is an aquatic weed that disrupts the ecosystems. Water hyacinth contains high protein and fiber. However, the content of crude fiber is difficult to be digested; therefore, water hyacinth needs to be transformed into low crude fiber animal feed by fermentation processes. The purpose of this study was to describe the quality of fermented hyacinth on various duration of fermentation and various concentration of bioactivator. The study was an experimental study with two treatments, i.e. variation of bioactivator concentration and fermentation duration. The concentration of bioactivator (yeast of tempe) were 0 g/kg (V0), 14 g/kg (V1), 17.5 g/kg (V23), 21 g/kg (V3) and 24.5 g/kg (V4), whereas the duration of fermentation were 5 days (L5) and 10 days (L10). The fermentation process for each treatment was 10 kg Hyacinth with 5 replications; hence the total number of samples was 50. Parameters measured in this study included the levels of protein, crude fiber, energy content and physical structure. The results of the analysis using two-way ANOVA showed that the best quality was resulted from the V1L5 treatment (14 g/kg and the duration of fermentation was 5 days), namely 11.09% crude protein, 21.16% crude fiber content and energy content of 1064.27 Kcal/kg. The physical structure of fermented hyacinth were crumbs, blackish brown, and it had the distinctive smell of tempe. Based on these results it is advised to process water hyacinth into animal feed by fermentation using yeast of tempe 14g/kg wet weight of water hyacinth for 5 days.

Abstract

One of central goal in ecology is to understand how plants respond to environment and what kind of attributes that can be obtained with an easy way to interpret the complexity of nature, especially on vegetation response. Ecologists use functional traits to understand how plants respond to environmental changes. Plant species may have experienced different environmental conditions during their ontogeny. Thus, they may show different patterns of ontogenetic trait variation (OTV) as their response to different environmental condition. In this study, the relationship between trait variation on different habitat and across ontogenetic stages both on community and population levels were investigated. Five selected leaves traits (leaf area, specific leaf area, leaf thickness, leaf dry matter content, and leaf succulence) were examined to look at plant response along soil water content and light gap interception gradient in Kenting forest dynamics plot (KFDP), Southern Taiwan. Leaf area was the most varied trait across habitat and ontogeny. Leaf thickness reveals an opposite pattern compare to leaf area. Leaf dry matter content (LDMC) showed less variation either between or within species and across ontogeny. Shift of community responses on environmental gradient by trait through ontogeny showed that intraspecific variation is important to be considered in ecological study. The other important finding in this study was by only using mean species we can misleading in understanding of plant responses to the environmental gradient in order to their adaptation both across different habitat and ontogenetic stages.

Abstract

Robusta is the most widely cultivated coffee in Indonesia (90% of the total Indonesian coffee production). Antioxidant activity and polyphenol content of Robusta coffee is higher than Arabica coffee or the other plants. One of the efforts, for coffee market expansion is product diversification through decaffeination of coffee . Decaffeination is one of process to reduce caffeine content. Decaffeinated coffee (decaff coffee) began to become public demand. In addition to its more delicious taste, low caffeine coffee is beneficial for health because it is safer to eat. Coffee decaffeination can utilize organic solvents that contain proteases. Tofu waste was one of protease sources. So that, tofu waste had potential as solvent in decaffeination The objective of the study was to assess the antioxidant activity of Robusta green coffee after going through decaffeination by using tofu waste. The study was used Factorial Completely Randomized Design, i.e . concentration of tofu waste (30%,60%, 90%) and length of immersion (3, 6, 9 hours). Robusta green coffee antioxidant activity was examined by using DPPH method. The results showed that the highest antioxidant activity ( 17.6061) was in the treatment of 90% waste concentration and 9 hours of decaffeination time. In conclusion, the greater the concentration and the longer the decaffeination resulted in the higher antioxidant activity. This study provides information about coffee processing methods that can produce coffee with the best quality. So, It can increasing the value of domestic coffee products especially in the global market and utilizing tofu liquid waste to be more malleable.

Abstract

Mount Seblat, as part a of Kerinci Seblat National Park (KSNP), is a pristine and natural mountain, particularly from disturbances and destructions by human activities. Nevertheless, the richness of biological resources especially plant diversity.in this area has not been more explored. The purpose of this study was to conduct an inventory of plant diversity and to determine the plant species composition. The inventory activities were conducted by plants collection along the ascent route. The results were then be maintained through ex situ conservation method in Cibodas Botanical Garden (CBG). The study was conducted by exploratory method, from Seblat Ulu Village (641 m asl) up to altitude of 1,037 m asl. There were 18 points of plant sample observation with an area of 5 x 5 square meters per point. Plant collection obtained 380 specimens. Five groups of most collected plants were Lauraceae (18 species), Rubiaceae (8 species), Anacardiaceae (6 species), Annonaceae (5 species), and Fagaceae (4 species). In order to enrich the plants collection as well as conduct the ex situ conservation effort, plants from Orchidaceae were also collected which resulted in 33 species. These results were an important initial inventory of plant diversity of Mount Seblat, considering that there was no record as well as very limited current information. When the environment disturbance tends to increase, this information may act as a reference and an initial database to develop plants conservation effort and strategy in the future.

Abstract

Indonesia had a high number of malaria cases where the treatments are only perceived by 10% of patients in health facilities. The resistance of Plasmodium sp. to drugs causes the difficulty of controlling malaria. The use of irradiation to produce malaria vaccine material is being explored until nowadays. In previously study that dose rate of gamma irradiation delivered to parasite was at the low dose rate (380 Gy/hour) which produced several doses that not be able to attenuate the parasite. This research aimed to increase dose rate (740 Gy/hour) and to determine the dose irradiation effect of 150-250 Gy to the protein profile, erythrocyte and leukocyte numbers in mouse blood infected by P. berghei erythrocytic stage. Results showed that there was an influence of dose rate of 740 Gy/hour for doses of 150-250 Gy in treated mice and no difference in erythrocyte, leucocyte and body weight with negative control. Dose of 150 Gy was the optimal dose to attenuate parasites, whereas doses more than 150 Gy effectively killed the parasites. The changes of protein profile marked by the appearance of higher number of bands at molecular weight of 30-37 kDa that predicted as merozoite surface protein of P. berghei and/or antibodies elicited in mouse.How to CiteRosadi, I., Syaifudin, M., & Elfidasari, D.

Abstract

Kecamatan Pangean di Kabupaten Kuantan Singingi memiliki sejarah yang lama dalam pemanfaatan berbagai jenis tumbuhan dalam kehidupan sehari-hari, diantaranya sebagai bahan makanan, obat atau prosesi ritual. Penelitian ini bertujuan memperlihatkan peranan Zingiberaceae oleh Masyarakat di Kecamatan Pangean Kabupaten Kuantan Singingi dan untuk kajian botani, etnomedisin, etnoekonomi, etnofarmakologi, etnoekologi serta etnoantropologi. Pengumpulan data dihasilkan dengan menggunakan kuisioner terhadap Masyarakat yang mengetahui manfaat Zingiberaceae dalam kehidupan sehari-hari, spesimen famili Zingiberaceae dikumpulkan dari lapangan. Karakter morpologi dikoreksi untuk identifikasi spesimen. Total dari sebelas spesies yang ditemukan adalah Curcuma Domestica, Zingiber officinale, Kaemferia galanga, Alpinia galanga, Zingiber cassumunar, Curcuma xanthoriza, Zingiber argenteum, Costus spesiosus, Zingiber sp., Globba pendula dan Alpinia mutica. Secara umum, semua spesies ini berperawakan herba. Dokumentasi kajian etnomedisin yang menggunakan famili Zingiberaceae dengan tumbuhan obat lainnya untuk memperoleh dosis yang tepat. Kajian etnoekonomi memiliki nilai ekonomi yang rendah dari famili Zingiberaceae. Kajian etnoekologi menunjukkan bahwa famili Zingiberaceae lebih banyak dibudidayakan dalam penggunaannya daripada berasal dari hutan, sedangkan dalam bidang antropologi, masyarakat memanfaatkan famili ini untuk ritual tertentu. Famili ini juga memberikan efek farmakologi jika masyarakat tidak memiliki takaran dan penyajian yang tepat.Pangean District in Kuantan Singingi has long history in using variuos kinds of plant in their daily life, either for food, medicine or rituals. The study was aimed to reveal the role of Zingiberaceae by the society of Subdistrict of Pangean, District of Kuantan Singingi, Riau Province, and to study the botany, as well as the role of plants in ethnomedicine, ethnoeconomy, ethnopharmacology, ethnoecology and ethnoanthropology fields. Data collection was conducted by distributing quetionaires to people who know the use of Zingiberaceae in daily life, the Zingiberaceae specimens were collected from the field. Morphological characters were carefully examined for species identification. A total of eleven Zingiberaceae species were identified in this study i.e Curcuma Domestica, Zingiber officinale, Kaemferia galanga, Alpinia galanga, Zingiber cassumunar, Curcuma xanthoriza, Zingiber argenteum, Costus spesiosus, Zingiber sp., Globba pendula and Alpinia mutica. Generally, all of these species were herbaceous. Ethnomedicine study documented the use of Zingiberaceae with other medicinal plants to get accurate dosage. Ethnoeconomic study revealed the low economic value of Zingibeaceae. Ethnoecological study showed that the cultivated Zingiberace was more common used than wild species, while the study of ethnoanthropology showed that people used some Zingiberaceae for specific rituals. This family give farmacological effect if the people didnt use the correct dosage and preparation.
