Macroscopic fungi is cosmopolitan-heterotrophic organisms which have an important ecological role in ecocystem. The aim of this study was to explore the diversity of species and the potency of Fungi in the Campus Forest of IPB Unversity. Observation was carried out in March to April 2019 using exploration method. Identification used morphological characteristic such as fruit body shape, hygrophnous, cap color, diameter, edge, and margin, wetness level, himenophore type. Result showed that 11 species of macroscopic fungi were identified, divided into 7 families, 4 order, and 1 class. The Group fungi were identified as Termitomyces sp. 1, Termitomyces sp. 2, Marasmius sp. 1, Marasmius sp. 2, Psathyrella sp., Geastrum sp., Stereum sp., Microporus sp., Polyporus sp., Ganoderma sp. 1 and Ganoderma sp. 2. All identified fungi were Basidiomycota. Some fungi found to be potentially used as food source, medicine, and also played an important role as a decomposer in the IPB university campus forest.

Microalgae is an aquatic microorganism that conducts photosynthesis. It plays a vital role as an oxygen producer in the marine ecosystem. A freshwater microalgae, Haematococcus pluvialis, has been utilized as a health supplement and industrial application which is beneficial for human. In addition to physical and chemical factors, nutrient composition is one crucial thing that contributes to the growth of microalgae. This present study aimed to determine and compare the growth rate of Haematococcus pluvialis cultivated in two culture medium, Walne’s and Guillard. The culture conditions observed were light intensity, photoperiod of light-dark hours, temperature, inoculum concentration of medium’s liquid, and cell density. This study confirmed that Walne’s media produced much higher biomass (247x104 cells/mL) than Guillard’s medium (209.6x104 cells/mL). The aspect to be further performed on H. pluvialis biomass is exploring its high-value bio compound.

The previous study stated that there are 12 species of Amphibians found in Lombok Island, Indonesia. Four of which are the endemic species of Lesser Sunda Islands, namely Oreophryne monticola, Limnonectes kadarsani, Limnonectes dammermani dan Hylarana florensis. However, the information regarding the habitat characteristic which supports animal survival is limited. This study aimed to explore the types of habitat characteristics according to amphibian diversity in the Island of Lombok. The survey study was conducted at 9 locations (3 of habitat type) from March to July 2016. The collected data includes species composition and a sum of individuals of species. Amphibian diversity was analyzed using relative abundance and the Shannon-Wiener index. This study revealed that the nonforest habitat type was appropriate for five species, while secondary and primary forest habitat type was appropriate for seven species. Diversity of species index directly proportional to a natural level of habitat (H’ Nonforest = 1.3; H’ Secondary Forest = 1.7; H’ Primary Forest = 1.8). The highest species abundance was Bufo melanostictus (23.9%), and the lowest species abundance was Oreophryne monticola (0.9%). According to the distribution and relative abundance, the species that require conservation priorities are Oreophryne monticola and Hylarana florensis.

Piebaldism is an autosomal dominant congenital disorder in pigment as a result of mutations in KIT gene, mapped on the long arm of chromosome 4. To Balo lived as a carrier of piebaldism genes. There are only four individuals of To Balo communities remained on Pujananting district, South Sulawesi. This study was a brief report and literature review about suspects of Piebaldism in To Balo. Data was collected by observation of depigmentation, interview and then depicted in pedigree. Phenotypic observations resulted in piebaldism on three individuals of To Balo, showed the same pattern and location of white patches. It is concluded that normal individuals could appear in third-generation when a woman or man carrier of piebaldism married with a normal individual.

Public Service Motivation: The Teaching Performance of Biology Teachers Suhirman Suhirman; Yusuf Yusuf

Publisher : Universitas Islam Negeri Mataram

The objective of this research was to explore the impact of Public Service Motivation (PSM) on the teaching performance of biology teachers at Madrasah Aliyah in Central Lombok Regency. The research method employed was a quantitative approach. This research was conducted on 32 samples of biology teachers at Madrasah Aliyah (High School) in Central Lombok Regency. Data were collected through a structured questionnaire containing statements filled out by respondents using a Likert Scale and scores of the respondent’s answer in each variable. Statistical calculations showed that the correlation value (r) between the Public Service Motivation (PSM) and the Teachers Performance variables was positive (0.278). However, the correlation between the Public Service Motivation and the Teachers Performance variables occurred was not significant. This present study suggests that Public Service Motivation has a positive correlation with the Teaching Performance.

Sintesis dan Optimisasi Produksi Kitosan Asal Cendawan Endofit Akar Cagar Alam ulau Dua Banten Rida Oktorida Khastini; Aris Munandar; Indah Juwita Sari

The cell wall component of root endophytic fungi is a main source of chitosan synthesis. This research aimed to optimize chitosan synthesis from three different isolated species of root endophytic fungi in Pulau Dua Nature Reserve, Banten Indonesia. Three species of root endophytic fungi, namely, Aspergillus niger, Aureobasidium sp., Basipetospora sp., were cultured to produce chitosan. To optimize the production of fungal chitosan, cultures were treated with different conditions such as growth medium (Oat Meal broth, Potato Dextrose Broth, CMMY Broth), pH value (4, 5, 6, 7), and temperature (25, 30, 35, 40°C). Chitosan was extracted from dried mycelium after treated on NaOH 10% at 121°C for 2 min. The degree of deacetylation (DD) of chitosan was then examined and compared with the control (shrimp chitosan). The optimum fungal chitosan condition was higher in CMMY medium, pH 5, and 30°C. The DD value of three root endophytic fungi species, Aspergillus niger, Aureobasidium sp., Basipetospora sp. were 88.5, 83.3, 80.8, respectively, which was lower than DD value resulted from control. This study indicates that Aspergillus niger was a potential endophytic fungi for chitosan synthesis.
