Sunandar A. 2017. Short Communication: New record of wild banana (Musa balbisiana Colla) in West Kalimantan, Indonesia. Biodiversitas 18: 1324-1330. Kalimantan Island (Indonesia) is part of the center of origin and diversity of wild bananas in Indo-Malesia region. West Kalimantan is one of province in Kalimantan Island. However, only a little information is available about diversity of wild bananas in West Kalimantan. The aims of this study were to study a possible new record of wild banana species in Nipah Panjang and Teluk Nibung Villages, Kubu Raya District and to describe its phenetic relationships among wild banana species based on morphological characters. By examination based on the morphological character, one species of wild banana was identified, i.e. Musa balbisiana found in Teluk Nibung Village (Local name: Pisang Klotok). However, we didn’t found any wild bananas in Nipah Panjang Village. M. balbisiana was a new record in West Kalimantan. Previously, M. balbisiana is widely distributed only in Java and Sulawesi. M. balbisiana was found in roadsides or backyards of residents in Teluk Nibung Village. Dendrogram of phenetic relationship showed that M. balbisiana from West Kalimantan had similarity with M. balbisiana from Sulawesi with coefficient of similarity 80%.

Profile of students’ creative thinking and conceptual understanding is essential to create an initial description of students’ competencies in overcoming their learning difficulties. The research aims to describe profile of concept understanding and creative thinking skills of 7thgrade students of all SMP Negeri (public junior high school) in Rasau Jaya sub-district, Kubu Raya Regency, West Kalimantan, Indonesia in photosynthesis content. The research uses qualitative descriptive method. The sampling technique employs disproportionate stratified random sampling. Samples consist of 143 students of 7th grade from three SMP Negeri in Rasau Jaya Sub-district, Kuburaya Regency, West Kalimantan, Indonesia. The data collection technique utilizes creative thinking skill test in the form of an essay with fluency, flexibility, originality, and elaboration aspects. Students’ concept understanding test is in the form of four-tier diagnostic test. Data analysis employs descriptive statistics with percentage of creative thinking and conceptual understanding in categories of understanding, partial understanding, misconception, and not understanding. The creative thinking skill percentage of SMPN students in Rasau Jaya, Indonesia in the originality and flexibility aspect is in a fairly creative category, whereas in the elaboration and fluency aspect the category is still less creative. The highest percentage of students’ conceptual understanding is misconception of 45.25% and followed by an understanding of 30.64%, not understand of 13.2%, and partial understanding of 10.97%. The obtained data give evidence that natural sciences (IPA) learning knowledge among junior high school students, especially concept understanding and creative thinking, is still low. Therefore, teachers could develop students’ creative thinking skills so their concept understanding could be improved.

Approximately, 325 cultivars of bananas were found in Indonesia. They have variation in shape, taste, color of fruit pulp, essential vitamins and mineral. The β-carotene is one of essential nutrient in banana with various concentration in every cultivar. The aims of this research were to describe the morphological characteristics and to analyze β-carotene content of mature fruits of three different genomic groups of Indonesian dessert and cooking banana cultivars namely Berlin (AA/ dessert), Barangan (AAA/dessert), and Kepok (ABB/cooking). Morphological characterizations of fruits were conducted according to Descriptor for Banana from International Plant Genetic Resources Institute. The β-carotene content of mature banana pulp was analyzed using High-performance liquid chromatography (HPLC) method with three replications. Banana fruit characters were analyzed based on 15 descriptors. The bananas were then subjected to clustering analysis. The result showed that β-carotene content were 27 μg 100g -1 , 5 μg 100g -1 , and 3 μg 100g -1 fresh weight respectively. Berlin showed the highest value of β-carotene. Cluster analyses formed two groups. The first group consists of Berlin and Barangan while the second one consists of Kepok. This study can be used as a reference for people to consume bananas with high content of β-carotene in meeting the needs of vitamin A and as a consideration for the plant breeding especially for β-carotene improvement purpose.

Indonesia is the center of origin of bananas, and also the center of diversity with approximately more than 325 banana cultivars were found in Indonesia. The anatomical feature is essential as a basis for classification as well as the morphological feature. This research aimed to describe the morphological and anatomical characteristics of diploid Musa balbisiana and triploid Musa paradisiaca 'Kepok' bananas. Morphological characterizations were conducted according to the IPGRI descriptors for bananas (Musa spp.). Musa paradisiaca 'Kepok' was collected from Pontianak West Kalimantan and Musa balbisiana was collected from Nipah Panjang village Kubu Raya district West Kalimantan. The root, petiole, and leaf were dissected from banana samples for anatomical preparation. The microscope slide was prepared using paraffin method, stained with 1% safranine and 1% alcian blue. The anatomical characteristics of root and petiole of diploid Musa balbisiana and triploid Musa paradisiaca 'Kepok' were considerably similar. The difference between diploid and triploid banana leaf anatomy was the number of hypodermal layers. These sort of anatomical characterization could be applied as a reference for banana cultivars breeding.

Borneo Island has a large number of wild banana species. As a part of Borneo Island, West Kalimantan has limited information about the diversity of wild bananas. This research aims to update the record distribution of wild bananas from Bonti District of Sanggau Regency and to determine their morphological characteristics. Exploration method and resident information were used in this study. Two species of wild bananas have been identified and considered as new distribution records in West Kalimantan Province, namely-Musa borneensis var. sarawakensis with morphological character pseudostem red-purple colour, sparse black-purple blotches at petiole base, leaf base shape rounded on both sides, male bud red-purple colour and Musa campestris var. sarawakensis with morphological character pseudostem yellow-green colour, inflorescence erect, leaf base one side rounded and one-pointed, the dorsally pink-purple and ventrally pink-purple colour of bract.

Scientific literacy research by the Program for International Student Assessment (PISA) in the period 2000-2015 shows that the scientific literacy ability of Indonesian students is at a low level. This study aims to determine the scientific literacy ability of state high school students in Singkawang City. The method used is descriptive qualitative. The research was conducted in two public high schools in Singkawang City, namely SMA 1 and SMA 2 Singkawang. The samples taken were 127 students selected based on the simple random sampling technique. The research instrument used was a scientific literacy test in multiple-choice questions consisting of the dimensions of context, knowledge and competence. The results showed that the average science literacy test scores of SMA 1 students in the context dimension were 38%, the knowledge dimension was 40%, and the competence dimension was 39% which were very low. SMA 2 has 40% context dimension, 41% knowledge dimension and 39% competency dimension, classified as very low. So it can be concluded that SMA 1 and SMA 2 Singkawang students have very low scientific literacy skills based on three dimensions of scientific literacy ability
