Integrating Abaca in a Mixed Forest Culture: A Livelihood Option for Smallholder Tree Farmers
Authors: Gonzal Lelita
Published: January 2020

This paper discuses the economic and ecological benefits of integrating abaca in established monoculture fruit trees and mixed forest culture, especially rainforestation farming. Integration of agricultural crops with high tolerance to shade, that will provide additional income to farmers and preserve the environment, is one of the key elements of a sustainable tree farming system. Inclusion of natural fibre plants such as abaca, a natural shade-loving plant, to the smallholder tree farming system will not only provide income opportunities to the farmers but also prevent soil erosion and conserve forest water. However, precautionary measures must be undertaken not to overshade the abaca since overshading causes the production of weak fibre. Integrating abaca in established monoculture fruit trees and mixed forest culture especially rainforestation farming is found to have a number of economic and ecological benefits.

Published: January 2020

Tree registration in the Philippines helps meet the legal requirements for harvesting and transport of timber, and is encouraged by the Philippines Government. To help improve information flow an extension primer was developed. The primer contains basic information on tree registration, harvesting, log transport and marketing. The development process involved input from staff of the Philippine Department of Environment and Natural Resources, tree farmers, furniture dealers, the Philippine National Police, the World Agroforestry Centre, Visayas State University and The University of Queensland. Key stakeholders were brought together at three workshops to review policy information and explore the interactions between, and differing opinions of, the various stakeholders. The primer has been distributed widely. Positive feedback has been obtained, although testing has shown that further improvements are possible. A revised version of the primer is to be produced.
Determinant Factors of Entrepreneurial Spirits among the Minangkabau Migrant Merchants
Authors: Cipta Hendra
Published: January 2020

This research aims to reveal the dominant factors of Minangkabau (the ethnic group native to the highlands of West Sumatra, Indonesia) migrants mainly engaged in merchandise. The Minangkabau hold firmly their customs and traditions which founded upon Islamic law as described in the saying “adat basandi syara’; syara’ basandi kitabullah” (tradition founded upon Islamic law, Islamic law founded upon the Holy Quran). This research was conducted in Ipuh sub-sub-district, Bengkulu province, Indonesia, those 150 respondents of Minangkabau merchants as the samples. The location was selected due to Ipuh sub-district is located near West Sumatra borders, so that the tradition strongly influence the Minang migrant merchants. To answer the research questions, the variables used were independent and dependent. The independent variable is the entrepreneurial spirit, while, the dependent variable is economic factors, adat (in this case, the term used is tradition), descendant, education, and independence. The research used a quantitative method by using multiple linear regressions. The result found that cultural variables influence the entrepreneurial spirits of Minangkabau merchant migrants because they uphold their traditions wherever they are. The insignificant influence of education, economic factor, heredity, and independence are insignificant. To conclude, matrilineal tradition has influenced the entrepreneurial spirits of Minang merchants and the matrilineal tradition can increase entrepreneurs among women.

Published: January 2020

The purpose of the study was to establish the sanitary state of pine plantations, identify the causes of the development and spread of diseases and pathogens, develop recommendations for improving the condition and increase the biological stability of pine plantations between the Dnieper and Desna rivers.
The studies were carried out in middle-aged, mature and over-mature pine plantations of the Ukrainian interfluve of Dnieper and Desna. The sanitary state of the stands was determined on 52 circular trial plots laid in the forest growing conditions of fresh poor site and fresh rich site. On each trial plot, the index of the sanitary state was calculated according to the generally methodology accepted in forestry.
Calculations of the sanitary state index showed that middle-aged plantations are more resistant to biotic and abiotic factors, the dominant number of trees is classified as weakened. In general, the sanitary state index of middle-aged pine forests of fresh poor site and fresh rich site is 2.04 and 1.79, respectively. The mature plantings of fresh poor site with sanitary state index 2.86 are highly weakened, and fresh rich site are weakened, due to the more fertile rich site soil conditions enriched by the biodiversity of the living ground cover. Pine plantations of ІХ and XI age classes, in which the sanitary state index varies between 2.30–2.33, and the percentage of drying and dead trees reaches 10 %, are weakened.
It has been established that the most influential factors of a significant deterioration in the sanitary state of mature and over-mature water-protection pine plantations are changes in the hydrological regime of floodplain territories, which leads to tree damage by the mistletoe Austrian and root sponge. In order to prevent the development of these pathogens, it is recommended to create mixed plantations of Scots pine with the introduction of 20–40 % deciduous species, which will simultaneously serve as a fire barrier to the spread of ground fires.
Key words: biological stability, state categories, indicator of sanitary state, Austrian mistletoe, roots sponge, dry wood.
Kajian Pengaruh Intensitas Suara Terhadap Bangunan Cagar Budaya Berbahan Batu Tahap II
Authors: Adhidhuto Linus Setyo , Kurniawan Jati , Amri Susilo Nur , Santoso Puji , Priyanto Ajar
Published: January 2020

Kegiatan konser musik atau acara lainnya yang menggunakan sound system besar sering dilaksanakan di Candi Borobudur, Candi Prambanan serta candi-candi lainnya. Hal ini menimbulkan kekhawatiran di kalangan pelestari cagar budaya akan dampak buruk suara keras yang dihasilkan oleh speaker terhadap cagar budaya.

Pada kajian tahap pertama telah dilaksanakan pengukuran getaran yang timbul pada lantai dan dinding pemikul beban candi akibat terpapar suara keras ketika berlangsung konser dan acara lainnya. Pada kajian tahap kedua ini dilakukan pengukuran getaran pada komponen batu candi bagian paling atas yang tidak menerima beban di atasnya sehingga tidak ada redaman tambahan akibat beban batu lain. Selain itu juga dilakukan percobaan getaran akibat suara dengan variasi ukuran serta susunan batu untuk dapat membuktikan terjadinya fenomena resonansi getaran.

Pengukuran kecepatan getaran akibat suara konser mencapai 0,0338 mm/s, masih jauh dari batas ambang getaran kejut oleh Kementerian Lingkungan Hidup sebesar 2 mm/s. Hal ini menunjukkan bahwa dengan adanya konser musik yang berlangsung di Candi Borobudur, Candi Mendut dan Candi Prambanan pada tahun 2017 dan 2018 tidak menimbulkan getaran yang berbahaya bagi struktur candi, baik itu getaran pada lantai, komponen pemikul beban dan batu teratas.

Fenomena resonansi batu pada frekuensi naturalnya bisa terjadi dengan pertimbangan bahwa batu berukuran kecil dan ringan, memiliki frekuensi natural yang rendah dalam rentang audiosonik, serta diapit batu lain dengan frekuensi natural yang mirip. Dari hasil kajian ini juga ditetapkan batas intensitas suara di depan speaker pada titik-titik yang sering digunakan sebagai panggung. Penetapan batas ambang ini didasarkan pada kesehatan manusia yang berada di lingkungan candi, mengingat kecilnya dampak suara terhadap bangunan dan struktur cagar budaya berbahan batu.
Comparison of growth and toxicity responses between non-toxic and toxic strains of Prorocentrum hoffmannianum
Authors: Lee TCH , Chan PL , Xu SJL , Lee FWF
Published: January 2020

We aimed to study the growth and toxicity responses of non-toxic (CCMP683) and toxic (CCMP2804) strains of Prorocentrum hoffmannianum under various nitrate and phosphate concentrations. The 2 strains were cultured in L1-Si medium with standard, depleted or 10-fold repleted nitrate or phosphate. CCMP683 cultured in standard L1-Si medium exhibited delayed growth. Nitrate or phosphate depletion decreased the cell density of both strains. Repletion of nitrate slightly increased the cell density of both strains. Repletion of phosphate also slightly increased the cell density of CCMP2804 but surprisingly decreased the cell density of CCMP683. Okadaic acid (OA) and its derivatives were not detected in CCMP683. OA was detected only in CCMP2804. Depletion of nitrate or phosphate increased the cellular concentration of OA, and repletion of nitrate or phosphate had no effect on the cellular concentration of OA. Correlation analysis indicated that the cellular concentration of OA was negatively correlated with cell density. Differences in the growth response to phosphate repletion and in the ability to produce OA suggest that the 2 strains may be good candidates for comparative studies related to phosphate metabolism and OA toxicity.

Nuevas tendencias en tipología: puentes híbridos, un campo para la innovación en la ingeniería estructural
Authors: Romo Martín José
Published: January 2020

Una de las características fundamentales de la actitud de Javier Manterola hacia el proyecto es la innovación. Su búsqueda de soluciones innovadoras le ha llevado a refinar los tipos estructurales canónicos hasta el límite. Además, su trabajo también incluye el desarrollo de soluciones estructurales más complejas que podrían decirse que constituyen estructuras híbridas, sobre las cuales trata este artículo.

Como se explica en el artículo, los puentes híbridos no son una invención contemporánea ya que su uso, más o menos consciente, es constante en la ingeniería a lo largo de su historia. Para el autor, la estructura híbrida podría ser reconocida como uno de los campos obvios para la creatividad y la innovación en la ingeniería estructural, siendo los trabajos de Javier Manterola el mejor paradigma de su uso.
Modern Tools and Methods of Epigenetic Protection of Healthy Aging and Longevity of the Homo sapiens
Authors: Romanchuk P. , Volobuev A.
Published: January 2020

The human brain is the main tool and the most valuable resource on our planet. New epigenetics Homo sapiens and H. sapiens brain manage the interaction of genetic and epigenetic programs of aging and healthy longevity. Epigenetic clocks are mathematical models and artificial intelligence that predict the biological age of a person using DNA methylation data and are the most accurate biomarkers of the aging process. Genetic and epigenetic factors that limit a person’s life expectancy are relevant in biogerontological, biophysical and neurophysiological studies, especially from the point of view of the medical economy. Cerebrovascular aging can be considered from several points of view, including changes in vascular density (number of capillaries and arterioles), vascular plasticity (dynamic regulation of vascular density or structure) and vascular reactivity (adaptation of vessels to acute metabolic changes in tissues). The main control mechanisms in the cerebral circulation are unique in comparison with other vascular channels and include, but are not limited to such features as the blood-brain barrier, perivascular innervation, intracellular communication between neurons, perivascular glial cells and smooth muscle cells, high tissue metabolism, lack of anoxic tolerance and the presence of collateral arteries. Multidisciplinary and multimodal interaction in the triad brain-eyes-vessels makes it possible to identify early biomarkers of both general accelerated and pathological aging, and to diagnose neurodegeneration in a timely manner, and to carry out effective neurorehabilitation of cognitive impairment. Biochipping, neural and brain chips, the next (new) generation sequencing technology will allow the study of the expression of thousands of genes that will be used as biomarkers. Combined and hybrid methods of neuroimaging in collaboration with artificial intelligence technologies are modern tools for the diagnosis and prevention of cognitive impairment and healthy aging of the H. sapiens brain.
Occurrence and Application in Linguistics the Term Chagatai Language
Authors: Akynbekova A.
Published: January 2020

Chagatai writing made a great contribution to the formation and development of culture in the history of Turkic-speaking peoples. Therefore, this article has studied the origin of the anthroponym Chagatai, used by the Turkic-speaking States during the XV–XIX centuries, and its use as a term in scientific works At the time, these issues generated a great interest of Soviet turkologists, and some domestic and Russian-speaking scientists conducted research in this direction, that is, they studied the language of official documentation and written monuments of the XV–XIX centuries. This article gave examples from their writings. In the works it was noted that Chagatai language was the literary language of the Turkic-speaking peoples in the territory belonging to Chagataikhan, the second son of Genghis Khan, after his death. Since then, the anthroponym Chagatai has been widely used as a term in scientific works, subsequently there were such terms as Chagatai writing, Chagatai language, Chagatai culture, Chagatai literature. The result based on the facts in the writings of scholars K. K. Udachin, B. M. Yunusalieva, K. Dyikanova, V. M. Flat, S. Kudaibergenov, V. V. Radlov, N. Ilmenskogo, P. M. Melioransky, K. Berkelman, A. K. Borovkov, N. Samoylovich, N. Vambery, Fuat Koprulu, G. F. Blagova, A. M. Scherbak, who carried out research in this area, it was concluded that the Chagatai language was the literary language of literate among many Turkic peoples who before the October socialist revolution on the basis of their native languages, the formation of the literary language was still at a low level. Therefore, it is concluded that comparing the materials of the modern Kyrgyz language with the Chagatai language, their proximity and kinship should be taken as an object of special research to reveal the causes of the history of the origin of the modern Kyrgyz language in the in-depth study.

This research conducted due to lack of information about fish larvae in Ranau Lake, South Sumatera. This information is quite essential to explore because this can be used as a scientific basis for policy formation in this area. The objectives of this research are to analyze the correlation between fish larvae abundance to physicochemical parameters in Ranau Lake waters. Sampling was carried out at six stations (Muara Silabung, Dermaga, Way Maisin, Pemandian Air Panas, Lumbok, and Talang Teluk). Physico-chemical parameters measured directly in the field are temperature, pH, depth, brightness, CO2, O2, hardness, electrical conductivity, total alkalinity, and turbidity; while the chemical parameters measured in the laboratory are COD, NO2, NO3, NH3, and PO4. Larvae species identified through DNA sequence. Principal Component Analysis (PCA) was used to measure the relationship between fish larvae abundance to the water parameters. Results show that generally there were forty-two fish larvae from nine species. The dominant species was Oreochromis niloticus. The results of the Principal Component Analysis show that the highest abundance of fish larvae was in water with the highest level of turbidity and dissolved oxygen, whereas the lowest abundance was in water with the highest level nitrate and depth.

Water hyacinth is a wild aquatic plant that grows quickly. The growth of water hyacinth need to be controled to prevent the flood and not to disturb paddy irrigation channels. Grass carp as herbivorous fish is used as natural predator to reduce the population of water hyacinth. The interaction between water hyacinth and grass carp is modeled using the prey-predator system. In this model there are harvest factors and predation factors using Holling type III. The optimal control problem is applied to minimize the mass of water hyacinth and harvest efforts of water hyacinth and maximize the mass of grass carp. The solution uses the Pontryagin Principle. The result is that the harvesting of water hyacinth and the grass carp can minimize the water hyacinth biomass at the end of time.
