Abstract

Fungal dyes are an eco-friendly alternative to synthetic dye. This study aims to evaluate additives to dye, using mixed fungi, to paint the picture on cloth. In the present study, the cloth was painted with mixed Aspergillus and Paecilomyces dye. The mixed fungi were grown on a mineral salt glucose medium. Five tests were conducted to evaluate additives to dye from mixed fungi that could be used to paint pictures on cloths to evaluate the effect of additives, a combination of additives producing tidy colors and other additives, the dye pH, mordant, and a variety of different mordants and the dye pH on color tidiness and hue. The additives used were alkali, acid, salts, glycerine, and urea.  The Royal Horticultural Society (RHS) color chart was used to measure the color of filtrate and range developed on the painted color on the cloth. The results showed that the mixture of vinegar or lemon as additives and the dye pH of 3 produced tidy colors. The mordant application had a more significant effect on the color that appears than pH treatment. Colors formed on images can add variations to textile painting.

Abstract

Tinjil Island is a semi-natural breeding facility for long-tailed macaques (Macaca fascicularis) managed by Primate Research Center, IPB University, located at the southern of Java Island and surrounded by the Indian Ocean. Long-tailed macaques are considered frugivorous even though they are well-known for their flexible diet. This study aims to analyse the vegetation supporting the population of long-tailed macaques. Data were collected from six tracks using square sampling plots with the size of 20 m x 20 m for trees as the main plot, inside the main plot were square subplots consisting of 10 m x 10 m for poles, 5 m x 5 m for saplings, and 2 m x 2 m for seedlings. The Important Value Index (IVI) was calculated for each level of vegetation. Hanjuang (Dracaena elliptica) dominated the seedlings with 29.35%, followed by Kampis (Hernandia peltata) with 18.73%, and Kalapari (Pongamia pinnata) with 13.73%. Hanjuang (Dracaena elliptica) also dominated the saplings with 26.83%, followed by Pancal (Syzygium antisepticum) with 19.19%, and Laban (Vitex pubescens) with 12.30%. The poles were dominated by Ki Cau (Dolichandrone spathacea) as high as 59.28%, while Waru (Thespesia populnea) and Ki Ciat (Ficus septica) dominated at 40.47% and 36.15%, respectively. Kampis (Hernandia peltata) dominated the trees with 39.28%, followed by Ki Ara (Ficus glomerata) with 35.56%, and Ki Langir (Dysoxylum amooroides) with 28.70%. Species found on Tinjil Island are mostly Moraceae (9.84%) and Fabaceae (9.84%), followed by Malvaceae (8.20%), Euphorbiaceae (4.92%), Myrtaceae (4.92%), and Anacardiaceae (4.92%). The vegetation in Tinjil Island supports the livelihood of long-tailed macaques on the island because they have an abundance of food and staple food such as figs to help them fulfil the energy needed to survive and reproduce.

Abstract

As a commercial fish, bullet tuna is constantly caught in purse seine fisheries to provide economic benefits for coastal communities. Biological information such as food preference has to be known due to their sustainability in the future. This research aims to figure out the food composition and preference of bullet tuna (Auxis rochei Risso, 1810) in Prigi Coast, Trenggalek Regency East Java. A total of 294 fish landed by purse seine fishermen have been collected from March up to May 2018. Each individual was measured in its total length and weight, then was dissected for sex determination,  measured the length of intestine, and analyse the stomach content. The data analysis encompasses frequency distribution of total length, relative gut length, frequency of occurrence, index of preponderance, trophic level, niche breadth, and food overlapping. The research result indicates that the main foods of Auxis rochei are fish and crustacean, while the complementary and additional foods were copepod, mollusc, annelid, and debris. Bullet tuna was a carnivorous fish with the trophic level of 3.7 and shows the existence of competition for food resources. Overlapping of feeding occurred in the 19-20 cm long group against the 23-24 cm long group in male fish and the 19-20 cm size group against the 21-22 cm length group in female fish. Bullet tuna use the same feed resources among the size groups of fish, where females use feed over a wider area than males.

Abstract

Local community groups have handled damage to the mangrove ecosystem on the coast of South Malang by carrying out restoration. The purpose of this study was to evaluate water quality in the restoration mangrove ecosystem based on phytoplankton diversity as bioindicators. A water and phytoplankton sampling was repeated three times with a depth of about 10-15 cm (below the surface water) at each location consisting of 4 restored mangrove ecosystems in Clungup Mangrove Conservation (CMC) and Kondang Merak as well as one natural mangrove ecosystem in Teluk Semut, Sempu Island, Malang Regency. Water quality parameters include water temperature, air temperature, conductivity, pH, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), nitrate, and orthophosphate content. The biotic index includes the Trophic Diatom Index (TDI) as an indicator of water nutrient content and Percentage Pollution Tolerance Value (%PTV) as an indicator of organic pollution. The water quality in the five mangrove ecosystems of CMC, Kondang Merak, and Teluk Semut has met the water quality standard for marine biota except for DO, nitrate, and orthophosphate content in several locations. Water quality in five mangrove ecosystems CMC, Kondang Merak, and Teluk Semut based on phytoplankton indicators did not show any contamination with toxic materials (H’). Based on TDI, it is categorized as eutrophic – hypereutrophic, except at the reference site of Teluk Semut mangrove; based on PTV polluted with moderate to high organic matter except at the reference site locations, namely Teluk Semut, and CMC 2. Thus, a location that has good phytoplankton bioindicators is Teluk Semut.

Abstract

The Lontar Usada Bali is a collection of the science of traditional medicine recorded in the lontar leaves. It contains information about the diversity of medicinal plants and treatment procedures used by Balinese for generations. However, most of the information stored in the lontars is only known by the Balians (Traditional Healers). The aim of the study was to investigate and document the diversity of medicinal plants known by Balians in Buleleng Regency, Bali Province, Indonesia. Direct interview with Balians, combined with purposive sampling (for the usada plants), was used in this study and conducted in August-September 2022. The data obtained comprised plant species, habitat, habitus, local names, plant parts used, and how they were used. The data were analysed qualitatively and quantitatively using diagrams, graphs, and tables and measured by the use-value index. Sixty-five species and 37 families of plants were recorded as a medicinal plant. The most widely used plant families by Balians were Zingiberaceae, Poaceae, Rutaceae, Euphorbiaceae, Lamiaceae, Lauraceae, and Malvaceae. In most cases, leaves were used, followed by tubers, fruits, and other parts. Maceration and powder or mushy were the primary modes of making herbal medicine, and external application was the most common method of drug administration. Most medicinal plants were obtained from the home garden, taken from nature, or bought in the market. Several diseases often treated by Balians were convulsions, itching, cramps, headache, black magic, stroke, herpes and tumor/cancer. This research is important to complete the ethnobotanical data on the diversity of medicinal plants in Bali. This data is important information for the development of new drugs and must be maintained for sustainability.

Abstract

Indonesia, particularly the island of Java, is dominated by a number of Shorea tree species (Dipterocarpaceae). Trees of the genus have been utilized for various practices, and they play a fundamental role in managing the stability of tropical forests. This study was carried out to understand the relationships between biomass and microfibril angle in Shorea spp. growing in West Java, where Shorea spp., are abundant. A total of 35 young trees belonging to 5 species were studied. The average age of these trees was 9 years, but in general there was a wide variation in tree diameter and total height. On average, biomass was the highest in S. leprosura and the lowest in S. palembanica. The lowest average microfibril angles (MFAs) were found in S. leprosura and S. mecistopteryx. The regression relationship between biomass and diameter was strong with an R2 value of 0.85, while the strength of the relationship between MFA and diameter was weaker (R2 = 0.195). In general, the MFA degree decreased with increased biomass accumulation Shorea species, which affects tree resistance to environmental variables and competitiveness in Indonesian tropical forests.

Abstract

Dacrycarpus imbricatus provides essential ecosystem functions and various potential uses. Therefore, studying this distribution and conservation status in Bali Islands is crucial. The Habitat Suitability Model (HSM) and Geospatial Conservation Assessment Tool (GeoCAT) were used to predict this distribution and conservation status. The results showed changes in the predicted habitat suitability in 2050. Climate change conditions will impact the preferential habitat of the current location. The analysis classifies D. imbricatus as an endangered (EN) species in Bali. The model does not consider anthropogenic factors which change the land use/land cover. Therefore, more severe conservation efforts in Bali are needed for this species.

Abstract

Chital is a native animal from South Asia. Chital had been introduced to many countries, including Indonesia. Chital was first introduced to Indonesia in 1811 at Bogor Palace and since had been kept captive around Indonesia. Currently, no research had been done concerning the genetic variation of Indonesian chital. Therefore, the purpose of this research was to analyze genetic variation and phylogenetic relationship of chital from Pusat Inovasi Agroteknologi Universitas Gadjah Mada (PIAT UGM), Prambanan Temple, Gembira Loka Zoo, and Bogor Palace, based on mitochondrial D-loop fragment. This study used a Polymerase Chain Reaction (PCR) method. DNA was extracted from faecal samples and amplified with L15995 and H16498 primers. The analysis used for this research were genetic variations, haplotype networking, and phylogenetic relationships between populations. This study detected 5 haplotypes out of 20 sequences with 10 polymorphic sites and 2 indels. The haplotype diversity and the nucleotide diversity were 0.443 and 0.002 respectively, and the genetic distance was between 0 and 2.03% (average 0.55%). This research also showed one main haplotype, labelled as haplotype 1, which consisted of all individuals from PIAT and Prambanan Temple, four individuals from Bogor Palace, and one individual from Gembira Loka. This grouping proves that the majority of chital population in Indonesia came from Bogor Palace. One individual from Gembira Loka has a considerable genetic divergence from the rest of the samples, which might indicate it originated from a different source population.

Abstract

Erek-Erek Geoforest (EEG) is one of the Biosites of Ijen Geopark located at the eastern slope of Mount Ijen. This location has unique topography of highland forests restricted by mountain ridges. This topography creates dense vegetation and humid ecosystem supporting microhabitats for endemic birds. This study aims to investigate the diversity and uniqueness of avifauna in EEG based on the existing value of birds. The method used is a point count at three potential station for the presence of birds. The data collected are the bird species, individual number of species, and species existence based on conservation status, distribution, and protection status. Data analysis includes the Shannon Wiener diversity index (H’), Evenness index (E), and existence factor (Ef) of bird community. The results show there are 57 species of birds belonging to 46 genera and 31 families. The diversity of birds in EEG Biosite has a high value (H'=3.40) and also a high evenness value (E=0.84). The Ef value of birds in this area is 51.35, which means the uniqueness value is a medium category. There are three bird species that have the highest Ef value, i.e Arborophila orientalis (Ef=80.00), Pycnonotus bimaculatus (Ef=73.33) and Locustella montis (Ef=73.33). The three species are endemic to Indonesia, especially A. orientalis whose distribution is limited to the highlands of East Java. Based on the composition, diversity, and uniqueness of avifauna in the EEG, it becomes valuable information for the government, Ijen Geopark Manager, and local communities to manage EEG Biosite conservatively by maintaining the existence of avifauna and their habitats.
