Abstract

Donacid bivalves vary in colour, pattern, and the shape of the shells. A population of donacid bivalves had been found in the northern shore of Madura Island, Indonesia. This study aimed to identify the donacids found in northern shore of Madura Island as well as to describe their variation on morphometric and morphological characters. Colour and pattern of 215 shells were observed and carefully photographed. Morphometric of the shells including the shell height, shell length, shell width, dorsal length, and umbo-margin length were measured and then their patterns were analyzed using regression analysis. The results revealed that there were two species of donacid bivalves in Nepa Beach, namely Donax cuneata and Donax faba with different morphological characteristics, including twelve different patterns and colours of the shells. These variations were described completely in this paper. This study contributes to the research on bivalve taxonomy, and is useful for the identification of donacid bivalves based on morphological characteristics.

Abstract

Justicia gendarussa Burm.f., a medicinal plant, is Acanthaceae that has many functions. Furthermore, the compounds in gendarussa must be produced in high quantity and quality by applying callus culture method. Accordingly, it is important to study the effects of plant growth regulators (2,4-D, IBA, and BAP) on callus induction of gendarussa leaves. This research design utilized a factorial design with two factors (2,4-D and IBA: 0.5, 1, 1.5 mg/L and BAP: 0.5, 1, 1.5, 2 mg/L). The experiment consisted of 24 treatments, each of which was repeated 3 times. Observation was carried out in 6 weeks. Data on the time of callus formation, percentage of explants formed callus, and callus morphology were analyzed descriptively,while data on fresh and dry weight were analyzed by Two-Way ANOVA (α = 0.5). Interestingly, the results showed that various concentration of plant growth regulators (2,4-D, IBA, and BAP) affected callus induction from leaf explants of gendarussa. We concluded that the most optimal treatment combination of concentration of plant growth regulators in inducing callus from leaf explants of gendarussa is 1.5 mg/L 2,4-D and 2 mg/L BAP with a relatively long period of callus formation at the earliest, i.e. on day 5, 2.247 g of fresh weight, 0.108 gof dry weight, white callus translucent, and friable. Moreover, the optimum treatment will be used to produce secondary metabolite and seed synthetic by cell suspension culture.

Abstract

Indonesia is the origin and center of diversity of banana. One of an edible banana in Indonesia is Pisang Awak (Musa paradisiaca cv. Awak ). In West Kalimantan, the ripe Pisang Awak has been processed into sale (dried banana). The aims of this research were to describe the morphological and anatomical character of Pisang Awak in West Kalimantan, Indonesia. In this study, Pisang Awak were collected from Padang Tikar I village, Batu Ampar Sub-district, Kubu Raya district, West Kalimantan. Morphological characterizations were conducted by following the instruction on Descriptors for Banana (Musa spp.) from IPGRI. The root, leaf blade, and petiole were fixed in FAA solution. Root, leaf, and petiole anatomy preparats were made by paraffin method. The lamina of Pisang Awak consisted of adaxial epidermis, two hypodermis layers, two palisade layers, spongy layer, bundle sheath cell, abaxial epidermis, laticifer. The petiole of Pisang Awak composed of three tissue systems, i.e., epidermis layer, parenchyma tissue and vascular tissue. The root of Pisang Awak consists of two epidermis layers, parenchyma and vascular cylinder. In the future, morphological and anatomical character in Pisang Awak could be applied as the basis of information for breeding programs of banana cultivars and classification.

Abstract

Mangrove plants are sensitive to environment condition. This research aimed to analyze the linkages of mangrove growth and environment dynamics and to estimate the growth of mangrove along with the environment dynamics. The research was conducted through the field experiment by the plantation of A. marina in silvofishery pond canals. Data collection was conducted for 18 months with 3 months observation interval. The environment variables observed including temperature, salinity, turbidity, pH, dissolved oxygen, TSS, sediment organic matter, nitrogen and phosphorus, and the growth of mangrove seedling. Analysis was conducted through regression and modelling with Powersim software. The result showed that the height growth was affected by dissolved oxygen, temperature, salinity, turbidity and pH, while the diameter growth was affected by TSS concentration. Inversely, the growth of mangrove also had a significant effect on temperature, change of organic matter and nutrient sediment concentration. Simulation showed that the height and diameter growth rates of A. marina seedling were dynamically changed among periods. Simulated seedling growth for one year forecast resulted in the rate of 0.115024 to 0.282294 cm/day for height and 0.001287 to 0.006031 cm/day for diameter. The simulation also indicated the continuous accumulation of organic matter and nitrogen over time. This research concluded that under limited environment dynamic, the growth of mangrove could be estimated. This model is a novelty in ecological studies. This research might initiates the more advanced ecological studies. Systematic estimation of ecosystem behaviour could be applied to formulate the best management practices, particularly in the silvofishery activities.

Abstract

Wild bee pollinators (Hymenoptera : Apiade) diversity and abundance were studied in three types of plantation forest on Mt. Slamet (Central Java Province, Indonesia). The aims of the research was to know the diversity and abundance of wild bee pollinators and to determine the possibility of plantation forest contribution on wild bees conservation. Sampling has been done at three stands: a pine forest (PF, with Pinus merkusii), an Agathis forest (AF, with Agathis damara) and a community forest (CF, with Albizia falctaria). Each habitat was divided into 5 line transect (100 x 5 m) and sweep nets were used to collect the wild bee samples. Sampling was done eah month from April to August 2015. The diversity of wild bees was high (12 species in 9 genera; members of the Apidae (7 species were dominant). The most abundant species across the forests were Apis cerana (343 individuals; 25.5% of total), Trigona laeviceps (195 individuals; 14.5%), and Megachille relativa (165 individuals; 12.3%). Measurements of species diversity (H’), species evenness (E), habitat similarity (Ss) and species richness indicated that the wild bee species diversity in the region was relatively high (H’ = 1.275) to (H’ = 1.730);(E= 0.870) to (E = 0.93). The result showed that the diversity of wild bees in three different plantation forest habitats on Mt. Slamet were similar and can be concluded that plantation forest types were important for pollinator conservation, and an appropriate future preservation strategy should include of the areas of all plantation forest types.

Abstract

Phylogenetic or population genetic studies have been focused on finding genetic variations in mitochondrial DNA (mtDNA) because mutations in this region contained five times higher than other genetic materials. The aim of this research was to generate PCR-RFLP D-loop mtDNA profiles of some Indonesian domestic waterfowl. The samples were 35 local ducks, 5 muscovy duck, and 5 geese. These local ducks included on seven types of Javanese ducks in Central Java, i.e. Magelang duck, Peking duck, Pengging duck, Tegal Branjangan duck, Tegal Jarakan duck, Tegal Blorong duck, and Tegal Lemahan duck. PCR technique was used to amplify the D-loop genes, and RFLP analysis of the D-loop was performed with AluIand RsaI. The results show that muscovy duck has no restriction sites in D-loop gene. Moreover, goose has a restriction site of AluI in D-loop gene at 550 bp and 187 bp; and it has no restriction site of RsaI. The analysis of RsaI-RFLP in mtDNA D-loop region of ducks resulted in 1 restriction fragment pattern which can be applied in the identification of duck to differentiate it from goose and muscovy duck. PCR-RFLP analysis duck D-loop mtDNA using AluI and RsaI restriction enzyme resulted in 3 combinations of restriction fragment pattern shown in 3 haplotypes (A, B, and C). Genetic diversity of Indonesian domestic waterfowl population could be identified by using PCR-RFLP analysis on mtDNA D-loop region. So far, there are few results of research on Indonesian domestic waterfowl genetic characteristics based on PCR-RFLP mtDNA D-loop marker. Also, this research has a good contribution on genetic characterization of local duck. The characterization is an important aspect to maintain breed quality and manage the genetic resources of Indonesian germplasm and in facilitating the breeding program.

Abstract

People’s concern about quail egg consumption has triggered the efforts to produce quail eggs with low cholesterol content by using organic feed. Organic feed is one type of feed rations made of mixing organic material. In this study, standard organic feed (rice bran, yellow corn, soybean, and fishmeal) and organic feed containing mackerel, cassava leaves, and turmeric powder was administere to female japanese quail. Organic feed containing mackerel, cassava leaves, and turmeric powder can affect the Japanese quail (Coturnix coturnix japonica L.) lipid profile. This research used experimental methods. Twenty-seven female Japanese quails were divided into 3 treatment groups (PO: commercial feed, P1: standard organic feed, P2: feed containing organic turmeric powder, cassava leaves, and mackerel) for 145 days with 9 repeat. Data obtained were in the form of average daily feed intake and blood lipid profiles of each treatment group. Further data analysis was performed by analysis of variance (ANOVA) followed by Duncan test. The results showed that administration of organic feed containing mackerel, cassava leaves, and turmeric powder can reduce the levels of cholesterol, triglycerides, and LDL but increase the HDL levels in Japanese quail. Supplementation of turmeric powder improve the chemical quality of Japanese quail eggs, so it is good for the development of quail embryos as well as for consumption. It can be concluded that organic feed and turmeric powder supplementation stabilize blood lipid profile and improve the reproduction of Japanese quail egg low cholesterol, so good for the development of embryo quail and for consumption.

Abstract

Feronia limonia (L.) Swingle better known as wood apple is an identity plant of Rembang Regency, Central Java Province, Indonesia. However, the population is very limited. In order to identify the conservation efforts, this ethnobotany study was aimed to determine traditional knowledge on the existence, economic value, utility, breeding technique and conservation of wood apple. The survey was conducted on a total of 102 local people from 10 sub-districts which were determined by proportionally stratified random sampling. Data were collected by questionnaires and individual interviews and then were analyzed descriptively. The results showed that all of respondents knew the figure of wood apple, but only 79.50% understood its status as an identity plant. Most of respondents (96%) stated that the fruits have low economic value, 80.39% respondents have utilized ripe fruit as ingredients of beverages and stems as firewood. This utilization was only equal to 29.72% compared to the potential usability based on research results. It was concluded that the traditional knowledge about the existence, economic value, and breeding technique were good and on the contrary, the knowledge about the plant’s usability was bad. The results will form a basic knowledge for in-depth studies to provide a government policy of Rembang Regency in order to develop an efficient strategy of management and conservation of wood apple as plant identity.
