Perakitan Kelapa Hibrida Intervarietas Dan Pengembangannya Di Indonesia
Get PDFThe Coconut Hybrid from Intervarieties Hybridization and its Development in IndonesiaThe objective of coconut intervarities hybridization in Indonesia is to find out some coconut accessions which are early bearing, high production, medium input, resistant to pest and diseases, spesific location , and suitable with consumer needs. Some of potential coconut hybrids produced by ICOPRI, such as Tall x Tall hybrids namely KB-1,2,3,4 and coconut hybrid Dwarf x Tall namely KHINA 1, 2, and 3 were released by the Minister of Agriculture in 1984. Moreover, some of Dwarf x Tall hybrids which were suitable for dry area and wet climate had been tested, there were GRA x DMT, GKB X DMT, GKN x DTE, and GKB X DTE. The production of those hybrids were approximately 3 tonnes copra/hectar/year with medium input. Coconut hybrids wich were tolerant to swampy area were GSK x DRU, GTT x DRU, and GKN X DRU, and there were also 25 coconut hybrids which were resistant to bud rot and nut fall diseases. PB-121 and NIWA hybrids were planted around 244,000 hectars, but the productions were not optimal. The problems faced in the field were that these hybrids need high input, sensitive to bud rot and nut fall diseases, and nut size was small so that it was not accepted by the consumers especially coconut factories. In the future, the development of coconut hybrid Dwarf x Tall is still needed to accelerate increasing of coconut productivity. The consept proposed for the development is using local coconut hybrids wich have characteristics early bearing, high production, medium input, medium to big size of nuts, resistant to bud rot and nut fall diseases and spesific location

Key Concepts: Sensory modulation dysfunction, sensory processing disorder, high threshold, low
threshold, sensory profile, low registration behaviour, sensory seeking behaviour,
sensory sensitive behaviour, sensation avoiding behaviour.
In order to treat a child with sensory modulation disorder (SMD), the impact of SMD on the child’s
occupational sphere should be taken into account. This includes the effect of SMD in the parent on
the child’s development and behaviour. This study determined the probability of agreement between
the parent and child’s sensory profiles.
A quantitative, cross sectional study design established the sensory profiles of 81 children and their
parents. Results indicated a moderate probability that a child with SMD may have a parent with
SMD. A moderate to high probability existed for a parent with SMD to have a child with SMD. This
supports the supposition that there is a hereditary component to SMD, with learned sedentary
behavioural patterns.
The treatment implications include considering the parent’s reaction to their own sensory thresholds
and the influence this has on the child’s treatment and learnt behaviour

The experiment was conducted at the District Tabukan Tengah and Manganitu Sangihe Regency, North Sulawesi in May 2012. The purpose of this study was to obtain genetic information for germplasm of sago Baruq, especially to determine the correlation between vegetative characters and the production of starch, which later can be used as the selection of mother palms. One of the tools that can be used to obtain this information was the method of path analysis. Research methods used was direct observation in the field. The number of plants observed for each site 1 0 trees, which were randomly selected. Characters observed were plant height, number of leaves, rachis length, length of petiol, petiol width, length of the leaf, width of leaf, number of leaves, stems weight, pith weight, and weight of starch. The collected data were analyzed to determine the direct and indirect relationship between vegetative characters and weight of starch using path analysis. The result showed that 10 vegetative characters of Baruq sago population in Tabukan Tengah District, Sangihe regency produced six characters directly influence the character of the starch weight and can be used as selection criteria to increasing production of baruq sago starch. Meanwhile, in District Manganitu 9 characters can be used as selection criteria for crop improvement. In addition to the direct effects, 12 indirect effects can be considered as a selection criteria for sago baruq population in District Tabukan Tengah and 10 indirect effects for the population baruq sago in the District Manganitu.

The moving and settling of plastic in the ocean: Forward and reverse time modelling of plastic particles
No full textThe growing amount of plastic pollution in the oceans is worldwide a huge problem. There is an increasing amount of projects that try to clean up this pollution. To remove the pollution efficiently, it is useful to know how plastic litter moves, degrades and sinks. Models are being developed that can describe what happens with plastic in the ocean. To model the behaviour of plastic in the ocean a lot of parameters need to be taken into account. The transport of plastic particles is largely determined by processes like the wind and the current but their movement also has a random character due to dispersion. Due to this random movement, the future position of a particle can be described by a probability distribution. To find that probability distribution, the Kolmogorov forward equation (or Fokker-Planck equation), in this context the same as the advection-diffusion equation, needs to be solved.It is also possible that the plastic particles sink and settle on the bottom of the ocean. One goal of this project was to incorporate the settling of particles as an extra term into the advection-diffusion equation. Forward models are used to predict where particles will go to. It can also be useful to have reverse time models that can describe where particles had their origin. To make reverse time models, it is necessary to solve a reverse time advection-diffusion equation. The main goal of this project was to derive and solve the reverse time advection-diffusion equation that includes the settling of particles. This is done by finding the adjoint of the Kolmogorov forward equation and the settling term.Applied Mathematics | Applied Physic
Modelling the lateral flow and sediment dynamics in estuaries
No full textEstuaries have always been important for mankind and therefore it is essential to have a good understanding of the flow and sediment dynamics there. The goal of this thesis is twofold. One objective is to use an existing model to gain a more thorough understanding of the flow dynamics in an estuary. The second objective is to extend the model such that it can also compute the suspended sediment concentration in a cross-section. The equations governing the flow dynamics are the shallow water equations. The advection-diffusion equation governs the sediment dynamics. To compute the flow and suspended sediment concentration in a cross-section, conditions are assumed to be uniform in the along-channel direction. To solve the equations a coordinate transformation is applied first. After the transformation, the cross-section of the channel is represented in the computational domain by a rectangle. In the vertical direction, an eigenfunction expansion is used with eigenfunctions derived from a special case of the Sturm-Liouville eigenvalue problem. In the horizontal direction, derivatives are approximated with a central finite difference scheme. In the frequency domain, variables are expressed as the sum of tidal components. The Galerkin method is applied in both the vertical direction and the frequency domain to optimise the weight functions for every location along the transect. The system obtained with the Galerkin method is solved using Newton-Raphson iterations and an LU-decomposition. To find the distribution of the erosion coefficient corresponding to a morphodynamic equilibrium, a time integration method is used. The effect of several parameters on the advective contribution to the cross-channel flow is systematically investigated. The results show that the steepness of the bottom slope affects the magnitude of the advective contribution to the residual lateral flow. For a steep bottom slope the contribution is large and for a gradual bottom slope the contribution is small. The curvature of the channel strongly affects the total cross-channel flow, depending on the magnitude of the radius of curvature, but hardly affects the flow caused by advection. The lateral density gradient can largely affect the \mbox{cross-channel} flow. Especially, the amplitude of the M tidal component of the density gradient affects the advective contribution to the flow. Both the magnitude and characteristics of the advective contribution change when the amplitude of the M tidal component of the density gradient is varied. The phase of the M tidal component of the density gradient hardly affects the cross-channel flow and advective contribution of the flow. Measurement data of a cross-section of the Ems is compared with a simulation of this situation. The magnitude of the lateral flow is similar for the measurements and model results but there is a difference in the direction of the flow in the upper part of the water column. This deviation could be caused by the description of the free surface. In the measurements there is a time-varying thickness of the water column whereas the rigid lid assumption is applied in the model. However, other differences between the simulation and the actual situation could have contributed to a deviation between the measurements and model results as well. The results for the sediment module show that the model works as expected for a prescribed erosion coefficient and for computing the erosion coefficient in morphodynamic equilibrium for situations with only diffusive transport. For simple situations the analytical solution is approximated and for more complicated situations the results agree with the physical intuition. The main recommendation for further research is to investigate how the model can be extended such that it is also possible to compute the erosion coefficient in morphodynamic equilibrium for situations with both advective and diffusive sediment transport.Applied Mathematics | Computational Science and Engineerin
Produksi dan Sifat Fisik Hidrogel Komposit Selulosa - Polivinil Alkohol
No full textTelah dilakukan penelitian pembuatan hidrogel berbahan dasar bioselulosa. Penelitian ini dimulai dengan observasi potensi penggunaan MSG sebagai sumber nitrogen dalam pembuatan hidrogel dengan menggunakan 4 perlakuan (ZA 0.5 (kontrol), MSG 0.5, 1.0, and 1.5%). Pada level MSG 0.5 and 1.0%, produksi lembaran tidak berbeda nyata dengan kontrol pada parameter berat gel dan water holding capacity (WHC). Sebagai tindak lanjut, resep pembuatan MSG 0.5% digunakan untuk membuat lembaran bioselulosa. Hidrogel yang telah dibersihkan dengan larutan NaOH dan Sodium Lauryl Sulfate, lalu diperkuat dengan 5% Polivinil Alcohol (PVA) menunjukan tingkat transparansi yang lebih tinggi dibandingkan dengan hidrogen tanpa PVA. Penambahan PVA mampu memperbaiki beberapa kekurangan sifat fisik pada hidrogel. Namun demikian, perlu dilakukan studi lebih lanjut untuk mendapatkan lebih banyak informasi mengenai sifat mekanis dari hidrogel tersebut.

Penelitian ini mempelajari keragaman tiga varietas kelapa genjah kopyor asal Pati yang telah dilepas berdasarkan karakter morfologi, kuantitas endosperma, dan keragaman alel marka SSR. Penelitian dilakukan di Pati dan di Laboratorium Plant Molecular Biology, Departemen Agronomi dan Hortikultura, IPB. Evaluasi dilakukan terhadap tiga populasi kelapa Genjah kopyor (hijau, coklat, dan kuning) dengan 30 tanaman sampel untuk setiap populasi. Rataan data morfologi digunakan untuk menyusun dendogram. Kuantitas endosperma diamati pada satu buah kelapa kopyor per tanaman yang dievaluasi. Karakteristik endosperma dikelompokkan sesuai kategori yang telah ditetapkan. Untuk setiap populasi, analisis marka dengan lima pasang primer SSR dilakukan pada 10 tanaman sampel. Data yang didapat digunakan untuk menentukan keragaman genetik kelapa Genjah kopyor asal Pati. Hasil pengamatan menunjukkan keragaman morfologis dan alel SSR antar tanaman dalam varietasnya (keragaman intra-varietas) rendah. Sebaliknya, keragaman morfologis dan alel SSR antar varietasnya tinggi. Kuantitas endosperma kelapa Genjah kopyor asal Pati bervariasi antara skor 1–6. Keragaman genetik yang rendah dalam varietas dan tinggi antar ketiga varietas (coklat, hijau, dan kuning) memperkuat pelepasan ketiganya sebagai varietas lokal. Selain itu, keragaman genetik antar tanaman dalam varietas yang rendah mendukung penggunaan ketiga varietas lokal sebagai tetua dalam program perakitan varietas kelapa kopyor unggul baru. Tetua yang dipilih dapat diseleksi intra-varietas berdasarkan persentase buah kopyor per tandan dan skor kuantitas endosperma yang tinggi
Strome lewende water : 'n interpretasie van Johannes 7:37-39 met verwysing na die huttefees, vir die konteks van wit Suid-Afrikaners in die 21e eeu
Get PDFThesis (MPhil (Ancient Studies. Centre for Bible Interpretation and Translation in Africa))--Stellenbosch University, 2006.This thesis explores the invitation and promise extended by Jesus in John 7:37-39 from the Jewish perspective against the background of the water libation ceremony that takes place during the Feast of Tabernacles, with the aim of offering an enriched interpretation of the text for Christian believers. Traditionally the words of Jesus in verses 37 and 38 are interpreted according to verse 39 as a reference to the pouring out of the Holy Spirit after Jesus has been glorified. Such an interpretation does not take into account the Jewish background against which the text is set.
The work gives a broad overview of the unique contents and message of the Gospel of John. The genre of the gospel is discussed, the author and the origin of the work are considered, as are the world of the author and the first readers, the composition of the text, the language and language usage and the purpose of the work.
A consideration of the interpretations of John 7:37-39 given by other commentators is offered in detail. Questions resulting from the text are discussed, such as which day is meant by the phrase “the last and greatest day of the feast” in verse 37, and, who is meant to be the source of the living water promised by Jesus in verse 38: Jesus himself or the believer.
The historical background of the Feast of Tabernacles is explored. The institution of the feast as a harvest festival as well as the connection of the feast with the exodus from Egypt and the re-institution of the Law after the Exile are considered. The elements of the feast as expressed in the text of the Old Testament are discussed and references to the feast in the texts of the Old and New Testaments are supplied.
The symbolism of water in the Old and New Testament is studied. Water is used as a symbolic expression of God’s power in the creation narrative and in God’s presence in nature. In the Old Testament water is also used as evidence of God’s blessing but when water is withheld it is seen as a symbol of God’s judgement.
My own interpretation of John 7:37-39 first considers the text as a narrative against the larger background of the Gospel of John, and second uses a socio-historical perspective of the passage with a consideration of the location of Jesus’ invitation against the backdrop of the events of the feast.
The situation of the ‘new’ South Africa after 1994 is described and the general feeling of pessimism amongst white South Africans is explored in the light of reports in the media and letters to newspaper editors. A parallel is drawn with the situation of the Jewish festival goers in John 7:37-39 to suggest that Jesus’ promise can also be applied to white South Africans to generate a positive feeling and a new identity. The conclusion is reached that the new life of blessing as promised by the text should not stop with the receivers but should flow through them to be a blessing to others.Master
