Abstract

Indonesia has the highest biodiversity that places ecotourism as a sustainable development sector. The negative impact of ecotourism is the vulnerability to invasive plant species growth. They invade the habitat of the native plants and potentially alter the biodiversity balance. This invasive plant introduction is predicted caused by tourist and hiker visits. Therefore, the inventory of invasive plant species is urgently needed. The field survey was conducted on March 11-12, 2017 to inventory invasive plant species along the Panderman Mountain hiking track that common travelers explored and then identified. Species of Pinus Caribaea, Chromolaena odorata, Lantana camara, Leucaena leucocephala, Pennisetum purpureum are categorized invasive plants. Four species of plants otherwise potentially invasive include Calliandra calothrysus, Ageratum conyzoides, Bidens pilosa, and Acacia deccurens. The widespread access to protected environmental destinations leads to the spread of highly invasive species. The impact of invasive species depends on factors such as reproduction rate, vegetative phase, adaptability of seeds that can withstand adverse conditions and in particular human vectors as a way of spreading them.Keywords: Batu, Ecotourism, Hiking track, Invasive plants, Panderman Mountain.

Abstract

Pisang Kepok is a major local banana cultivar in Indonesia with high economic, social and cultural value. Particularly on the island of Java, there are several variations of Pisang Kepok recognised with their own local names, which makes difficulties in taxonomic identification and grouping. Morphological features are used in conventional banana cultivar classification, but they are deemed less precise due to their subjectivity, thus, it is supposed to be complemented with a molecular approach. This study aims to identify the phenotypic variation of Pisang Kepok local cultivars also their genetic polymorphism using Random Amplified Polymorphic DNA marker. Phenotypic variation was observed using 35 morphological characters. Six RAPD primers were used, i.e. OPA2, OPA3, OPA4, OPA11, OPA12, and OPA18. Clustering analysis, both phenotypic and genetic were performed using PAST v4.02. The morphological characterisation identified four variants of Pisang Kepok i.e. Kepok Abang, Kepok Putih, Kepok Manurun, and Kepok Australi; which all confirmed as ABB genome group. Phenotypic clustering showed that Pisang Kepok cultivars were separated into 3 clusters based on their local name, with a high similarity value of >90%. PCA biplot showed that the fruit flesh colour was the most important character contributed to the cultivar variation. RAPD marker also showed that each specimen was grouped according to its local name and source, with a similarity value of >80%. Both morphology and molecular (RAPD) markers resulted in the branching of Pisang Kepok which was closer to Pisang Klutuk than Pisang Barlin.

Abstract

Porang (Amorphophallus muelleri Blume) dispersed and grows well in Java island. This research aimed to determine the genetic diversity of porang populations in Central Java and West Java based on LEAFY second intron (nuclear genome encoding flower development). DNA samples of porang were from previous study, which are obtained from Central Java (Pamedaran, Grobogan, Wonogiri, Karangtengah) and West Java (Cisompet) as ingroup. A. variabilis from Pamedaran Brebes, A. ochroleucus, A. longituberosus, A. sumawongii, and A. tinekeae from genbank were treated as outgroup. LEAFY second intron was amplified using primers FLint2 F1 5’-CTTCCACCTCTACGACCAGTG-3’ and FLint2 R1 5’-TCTTGGGCTTGTTGATGTAGC-3’. Analysis using dnasp5 showed that 23 samples had 89 invariable sites and 139 variable sites that consisted of 12 singleton two variants sites, 118 parsimony-informative two variants sites and 9 Parsimony-informative three variants sites. The total of haplotype were 7 haplotypes where 16 ingroup samples clumped on haplotype 1 whereas 2 samples of Grobogan (Grobogan I and Grobogan III) clumped on haplotype 2 and outgroup samples occupied at their own haplotype. Genetic distance of all ingroup samples were 0-0,004 showing no differences among individuals. Analysis of phylogenetic tree using Maximum Parsimony, Neighbor Joining and Maximum Likelihood resulting a polytomy branch of ingroup samples except Grobogan which forms a separated sub clad. Key words: Genetic diversity, haplotype, Java, LEAFY, Porang.

Abstract

This activity is motivated by the products of the Gadingkulon villagers who have low bargaining power, their lack of ability in packaging and selling products is also an obstacle. Besides, many business actors have not pocketed and are not sufficiently knowledgeable about halal certification from MUI for the products they produce, so they will find it difficult to market their products to souvenir centers, supermarkets, and other markets. Guaranteed halal products through halal product certificates will provide comfort, safety, safety, and certainty of the availability of halal products for people in consuming and using halal products and can increase added value for business actors to produce and sell halal products. Therefore, they need to be equipped with knowledge and training on halal certification steaming. This service activity consists of 4 stages, namely preparation, meeting, training, and monitoring and evaluation. The community service activities carried out in Gading Kulon Village, Dau District, Malang Regency are going well. The result of community service activities is that people who have joint products with the Halal Center of UIN Maulana Malik Ibrahim Malang help meet and identify all the requirements needed and will then be bridged by the Halal Center of UIN Maulana Malik Ibrahim Malang until the issuance of halal certificates.

Abstract

This study aims to identify tree species and their potential as carbon stock in three urban forests of Malang City. This research was conducted in three urban forests including the Urban Forest of Malabar, Velodrome, and Hamid Rusdi. Data were analyzed with an important value index (IVI) and Carbon stock estimation. There were 41 species of trees in three Malang City Forests. There are differences in tree dominance in the three Malang city forests, namely: the Malabar city forest is Albizia chinensis, the Velodrome city forest is Gmelina arborea, and the Hamid Rusdi city forest is Polyalthia longifolia. The highest value of carbon stock in the Malabar urban forest is A. Chinensis, 6,214.38 kg; in the Velodrome urban forest is Enterolobium cyclocarpum, 7,225.88 kg; and in the Hamid Rusdi Urban Forest is Samanea saman with a carbon stock of 4,757.01 kg.
