Abstract

Annona is a genus belongs to Annonaceae family, consisting of numerous species that produce edible fruit.   Four species namely A. glabra, A. montana, A. muricata and A. squamosa collections of Purwodadi Botanic Garden  were recorded for its flowering and fruiting times, since November 2010 to April 2013. The data were scored and complemented with climate data (temperature, rainfall intensity, humidity) then analyzed using multiple linear regression analysis.  The result showed that humidity was the most affected climate factors on the flowering and fruiting times of those species.  Specifically, rainfall intensity (0-550 mm) affected to  Annona muricata, temperature (25,56-28,33 °C) and humidity (66,83-85,02%) to  Annona squamosa, and  humidity to  A. glabra (71,62-85,02% )  and  A. montana (71,62 to 82,94 %) as well. Flowering time of A. glabra occurs three times a year in wet and dry, and fruiting occurs twice a year in the same month. Annona muricata is flowering throughout the year and fruiting twice a year in wet. A. montana and A. squamosa recorded one a year during the wet month.

Abstract

This study aimed to compare local dairy farmer ration formula with national research council in producing higher feed efficiency and milk production. This study had two stages. The first stage was in vitro study of dairy farmer rations which have different raw materials (R3, R4, and R5) with NRC based ration (R2) and Demo Farm ration (R1). The variables measured in this stage were proximate composition, volatile fatty acid, ammonia, dry matter and organic matter digestibility. The first stage used a randomized block design with five treatments, three groups of ruminal fluid, and three replications. The second stage used nine lactating cows with three periods of lactation (one, three, and other) and used a randomized block design with three treatments, three groups, and one replication. Parameters measured were dry matter intake, manure score, milk production, body weight gain, body condition score, and technical and economical efficiencies. The first stage result showed that R1, R2, and R3 were three best rations in nutrient composition and fermentability (ammonia and volatile fatty acid concentrations were optimum for microbial growth and high digestibility), so in conclusion those three rations were the best rations and should be compared by in vivo method. The result of the second stage showed that all tested rations were not significantly different in milk production, performance and efficiency, so in conclusion those three rations have the same quality. Key words: dairy cattle, milk production, profitability, rations test

Abstract

Annonaceae species of Purwodadi Botanic Garden collections from East Java encountered problems in species identification based on morphological characters. In addition, the unavailability of molecular data to support identification based on morphological characters hinders accurate identification of species. The aim of this research is to discern phylogenetic of Annonaceae species from East Java collections of Purwodadi Botanic Garden based on coding and non-coding sequence DNA. Annonaceae species used in this study are 30 species, includes outgroup from family of Magnoliaceae. Materials for DNA analysis were young leaves which were processed through DNA extraction, DNA amplification through PCR technique, DNA sequencing and data analysis with Maximum Likelihood (ML), Maximum Parsimony (MP) and Neighbour-Joining (NJ) method analysis. The results show that phylogenetic tree is divided into two subfamilies, i.e. Annonoideae and Malmeoideae. The topology of phylogenetic tree from three DNA molecular marker shows that non-coding sequence DNA (trnL-F molecular marker) has the best grouping of relationship and be able to explain the relationship between species of Annonaceae than rbcL and matK molecular marker as coding sequence DNA. Bootstrap value of trnL-F tree is very weak to high (36-100%) while rbcL is very weak to weak (17-63%) and matK tree is high (98-99%).

Abstract

Communication is done not only verbally but nonverbal communication often we use to deliver the message. Nonverbal communication is also used by autistic children to interact with their environment. The formulation of research problem is how nonverbal communication behavior of autistic children during the learning process in SMPN 46 Surabaya along with the meaning of nonverbal communication shown by children with autism are nonverbal communication during the learning process in SMPN 46 Surabaya and to categorize the meaning of nonverbal communication hehavior of an autistic child demonstrated during the learning process takes place that uses kinesics communication theory as a reference. The result of this study indicate that nonverbal communication shown by children with autism is very diverse. However, by using kinesic Theory of Communication as a reference it can be seen how nonverbal communication shown children with autism as well as the meaning of nonverbal communication that is shown by the autistics child.

Abstract

Mesua ferrea L. and Swinglea glutinosa (Blanco) Merr. are two species of plants with recalcitrant seed character. Recalcitrant seed have problem with storage, because they cannot stand being stored for long periods of time. Storage method becomes indispensable in recalcitrant seeds conservation. The storage methods were using 3 treatments, namely media of storage, storage time and room of storage, analyzed by using factorial design with 2 replication. Each treatment combination was tested for seed moisture content, rate of germination and seed germination value. The results showed that the viability of M. ferrea seeds can be maintained up to 55 percent ―90 percent if they were stored for 2 months, at either room temperature or freezer temperature put in a glass jar with silica. Seeds of S. glutinosa have germination percent in a range of  83.33 percent ―93.33 percent after being stored for 1 month at room temperature, wrapped with aluminium foil, as well as stored under freezer temperature put in a glass bottle containing silica. Based on this test, both of seed species are recalcitrant because they cannot stored for long time periods.

Abstract

Diospyros cauliflora Blume and Diospyros lolin Bakh are some of endemic plants from Indonesia which included on Ebenaceae family. Their distribution in Maluku Island, especially in Seram and Morotai Island. Morphometric analysis of D. cauliflora and D. lolin is important to know the genetic diversity of them, because reference of Diospyros morphometric analysis evaluation in Purwodadi Botanical Garden are not documented. Plant materials (branch, trunk, leaf and fruit) of D. cauliflora and D. lolin from Purwodadi Botanic Garden, Pasuruan-East Java, are analysis. The results showed that genetic diversity of D. cauliflora and D. lolin are high. High variation within species of D. cauliflora and D. lolin cause high polymorphism. Morphometric character of D. cauliflora that must conserve in the future are plant height (TT), plant height bole (TTBC), diameter of branch (DC), length of petiole (PP) and sum of seed on one fruit (BI). D. lolin morphometric character are length of petiole (PP), length of leaflet (PL), diameter of canopy (DT) and sum of branch (JC). Their character can be used to key character of plant identification of D. cauliflora and D. lolin. Keywords: Diospyros, Genetic diversity, Morphometric, Purwodadi Botanic Garden
