Effects of biotic and abiotic environmental stimuli on the morphology and biomass allocation of Mimosa pigra L.

The main focus of this study was to examine the morphology of Mimosa pigra, an invasive weed in response to artificial biotic and abiotic stressors. Seedlings of M. pigra were subjected to stressors such as seed sowing density, leaf defoliation and water regime. Comparatively, morphological performance related to different sowing practices differed significantly (p0.05) in morphological performance under different levels of water regime. However, seedlings that received low water (LW) treatment showed better growth performance than seedlings that received high water (HW) treatment, which had the lowest morphological traits and biomass allocation

Weed survey in different cultural practice in Seberang Perai and Muda Rice Fields in Northern Malaysia

A correlation between weedy species composition and 4 different planting practices in Peninsular Malaysia was being investigated from September 2011 – January 2012. Through this study, the noxious and competitive weed of rice were identified and counted, which should be helpful in developing a more sustainable weed control and management. This study was conducted at 24 different rice field covering four types of planting practices in Seberang Perai and MUDA area, namely wet seeding, water seeding, manual transplanting and mechanical transplanting method, using 0.5 x 0.5 m size quadrat with 20 samples for each field during rice at tillering to heading stage. A total of 27 weed species belonging to 14 families composing of 10 broadleaved, 8 grasses, 7 sedges and 2 submerged weed group were recorded. The dominance weeds species in four planting practices at both areas is Oryza sativa complex (weedy rice). Different dominance weed group observed in both areas due to different planting practices, such as in water seeding practice, broadleaved such Limnochoria flava and Monocharia vaginalis showed the highest I.V. for both areas, for wet seeding practice Echinochloa crus-galli and Leptochloa chinensis under grasses group have the highest I.V. and for manual and mechanical transplanting practice both have the same weed group which is Leptochloa chinensis.

A Snapshot of Woody Plants Composition in Byram Permanent Mangrove Forest Reserve

The term mangrove may refer to an ecosystem or individual plants where the distribution of woody plants usually influenced by climate, water salinity, tides, type of soil in the mangrove swamps and environmental activities including development, housing and industrial. Thus only a certain species that can survive under this extreme condition. A study had been conducted in Byram Permanent Mangrove Forest Reserve to provide baseline information on the distribution pattern of plant growth in mangrove area. The main objective of this study is to determine the composition and the distribution pattern of true-mangrove woody plant species. To assess the species composition, the forest reserve nearest to the sea, which run approximately 2.0 km, parallel to the sea, was divided into three main sections (i.e. 600 m each section with a minimum 50 m wide border between the sections). Species enumeration was conducted in 11 plots, where each plot size is 10m x 10m. In general these plots were established in random stratified manner, from the sea towards the terrestrial part of the mangrove forest. In total, we recorded 290 of individual woody plants. The most abundant species in term of occurrences within all zones and forest section is Bruguiera parvifolia

Effect of Artificial Defoliation on the Emergence of Foliar Buds of Mimosa Pigra

This study was specified in documenting Mimosa reaction in the state of defoliation on the plants. As defoliation was believed to cause plants experiencing both positive and/or negative effects on its growth performance, thus among the aim of this study is to monitor the emergence of foliar buds in respond with vary level of defoliation intensities. The seedlings were grown singly in polybags up to four leaf stage as. Grown seedlings were randomly subjected under four different defoliation intensities: control (un-defoliated), 25%, 50%, and 100% in which 10 replicates of seedling for each treatment. Experiment was ceased at the 6th month after establishment of plants grew. Results shown that, the effect of defoliation on the production of foliar buds was significantly difference between the treatments (P< 0.05). As compared with 25%, 50% and 100% defoliation, un-defoliated plants showed the highest amount of foliar buds production which is 14 buds. While, there were no differences amount of foliar buds production between 25% and 50% defoliation with 5 foliar buds per plants. Emergence of foliar buds was reportedly lowest in 100% defoliation plant when there were no sign of buds emergence. Results concluded that, the subjected plants of control, 25% and 50% leaves defoliation treatments, were able to performed tolerance effect relative to the induced stressor. Apart from that, experiment revealed that the 100% defoliation has probability of detrimental effect on growth and reproduction of Mimosa seedling as it hindrance the germination of foliar buds

Study on micro-patterning process of vertically aligned carbon nanotubes (VACNTs)

Vertically aligned carbon nanotubes (VACNTs) have drawn significant attention by the researchers because of their nanometric size and favorable material properties. Patterning of CNT forests in the micrometric domain is very important for their application in the area of microelectromechanical system (MEMS). For the first time this paper reports, detailed experimental investigation on a post growth m-patterning process of VACNT forests. The micromechanical bending (M2B) process was locally applied at the targeted area in order to change the alignment of VACNT forests. Interestingly, the VACNT forest was transformed from typical black body absorber to reflective mirror as the M2B process was applied. Several parameters were identified that govern the resultant patterns such as rotational spindle speed, lateral bending speed, step size, tool morphology, and total depth of bend. Optimization of the parameters was carried out experimentally to obtain the best surface roughness and integrity of the microstructure. A minimum average surface roughness of Ra D 15 nm was achieved with 2000 rpm spindle speed, 1 mm/min bending speed and 1 mm step size

PELATIHAN PENGOLAHAN BUAH NANAS MENJADI SELAI NANAS SEBAGAI PELUANG BISNIS WARGA

ABSTRAKKecamatan Lembak yang berada di Desa Tapus merupakan salah satu daerah yang berada di Kabupaten Muara Enim yang memiliki potensi sumber daya alam yang sangat bagus. Kecamatan Lembak menjadi tujuan utama (Placeholder1)untuk pelaksanakan KKN - Tematik Universitas IGM. Salah satu potensi alam yang dimiliki Desa Tapus adalah perkebunan nanas. Di Desa Tapus ini memiliki jenis tanah yang kering yang mengandung pasir dan mengandung kapur yang rendah, dengan begitu sangat cocok untuk dibuat perkebunan nanas. Dengan adanya hasil nanas ini, banyak warga sekitar yang menjadikan nanas sebagai salah satu mata pencarian mereka. Namun sayangnya, dengan banyak warga yang mempunyai perkebunan nanas ini menjadikan harga nanas menjadi sangat rendah dan tidak dapat dimanfaatkan dengan baik. Maka dengan diadakannya pelaksanakan KKN - Tematik Universitas IGM ini, kami sebagai mahasiswa bertujuan untuk memajukan UMKM yang ada di Desa Tapus ini dengan membantu warga sekitar bagaimana cara memanfaatkan hasil nanas dengan baik, yaitu menjadikan selai, meneliti bahan pokok yang berpotensi dapat berkembang, dan mengajarkan bagaimana menjual, mempromosikan, bahkan memproduksi hasil nanas agar dapat diperjual belikan dengan harga yang tinggi dengan kualitas yang baik. Maka dari itu, kami sebagai mahasiswa berharap dapat membantu UMKM yang ada di Desa Tapus menjadi berkembang lebih baik lagi. Kata kunci: UMKM; pemberdayaan; nanas ABSTRACTLembak Subdistrict, located in Tapus Village, is one of the areas in Muara Enim Regency which has very good natural resource potential. Lembak District is the main goal for implementing the IGM University Thematic KKN. One of the natural potentials of Tapus village is pineapple plantation. In Tapus Village, the type of dry soil that contains sand and contains low lime is very suitable for making pineapple plantations. With the results of this pineapple, many local residents who make pineapple as one of their livelihoods. But unfortunately, with many people who have pineapple plantations, the price of pineapple is very low and cannot be used properly. So with the implementation of the IGM University Thematic Community Service Program, we as students aim to advance MSMEs in Tapus Village by helping local residents how to make good use of pineapple products, namely making jam, researching staple ingredients that have the potential to grow, and teaching how to sell, promote, and even produce pineapple products so that they can be traded at high prices with good quality. Therefore, we as students hope to help SMEs in Tapus village to develop even better. Keywords: UMKM; empowerment; pineappl
