Background and objectives

Marijuana use has become more widely accepted in the United States and has been legalized in many areas. Although it is biologically plausible that marijuana could affect kidney function, epidemiologic data are lacking.

Design, setting, participants, & measurements

We conducted a cohort study among young adults with preserved eGFR (i.e., eGFR≥60 ml/min per 1.73 m2) using data from the Coronary Artery Risk Development in Young Adults (CARDIA) study. At scheduled examinations occurring every 5 years and starting at study year 10 (calendar years, 1995–1996), cystatin C was collected over a 10-year period, and urine albumin-to-creatinine ratio was collected over a 15-year period. We investigated the cross-sectional association between current and cumulative marijuana use (in marijuana-years; one marijuana-year equals 365 days of marijuana use) and eGFR by cystatin C (eGFRcys) at year 10. In longitudinal analyses, we investigated the association between cumulative marijuana use and eGFRcys change and rapid (≥3%/year) eGFRcys decline over two 5-year intervals and prevalent albuminuria (urine albumin-to-creatinine ratio ≥30 mg/g) over a 15-year period.

Results

Past or current marijuana use was reported by 83% (3131 of 3765) of the cohort, and the mean eGFRcys was 111 ml/min per 1.73 m2 at year 10. Over the following 10 years, 504 had rapid eGFRcys decline, and over the following 15 years, 426 had prevalent albuminuria. Compared with no use, daily current use and ≥5 marijuana-years of cumulative use were associated with lower eGFRcys at year 10: −4.5% (95% confidence interval, −8.1 to −0.7%; P=0.02) and −3.0% (95% confidence interval, −5.6 to −0.4%; P=0.03), respectively. Marijuana use was not significantly associated with eGFRcys change, rapid eGFRcys decline, or prevalent albuminuria.

Conclusions

Although we identified a modest cross-sectional association between higher marijuana exposure and lower eGFRcys among young adults with preserved eGFR, our findings were largely null and did not demonstrate a longitudinal association between marijuana use and eGFRcys change, rapid eGFRcys decline, or prevalent albuminuria.

Teaching Collegiate Ethics in a Nation with Laws that Permit Mutilation of the Unborn
Authors: Oeding Jill M. , Seitz Jamie L.
Published: August 2017

The devaluing of life through abortion has a detrimental effect on the ethical decision-making processes of a nation of people. Encouraging college students to make ethical decisions in a nation with legalized abortion is challenging. Laws that permit women to have a voluntary abortion are in direct conflict with ethical decision-making. The consequences of decades of abortion in the United States are staggering. Approximately one abortion is performed for every five live births. Over 58,000,000 babies have been aborted in the United States since 1973, when the Supreme Court found that women have the “constitutional right” to have an abortion before “fetal” viability. The authors compared the current abortion law to other “black eyes” in the United States’ history including: slavery, the Separate But Equal doctrine, the treatment of Native Americans, and oppressive child labor. This paper then introduces a four-step ethical decision making model and a “toolbox” of questions that students may use when analyzing ethical issues.
The Opportunity Costs of the Alaska Permanent Fund Dividend
Authors: Marks Roger
Published: August 2017

The Alaska Permanent Fund was established by the State of Alaska in 1976 to save a portion of windfall revenues resulting from the discovery of the large Prudhoe Bay oil field. The Permanent Fund Dividend program, established in 1982, pays out about half the earnings of the Fund to each resident. The dividend was intended to both create a constituency for sound management of the Fund, and directly distribute the State’s resource wealth to its citizens. The dividend has achieved great popularity, and has succeeded in allocating resource rents to boost jobs and personal income, and reduce poverty, while the Fund itself has grown. It has also protected the Fund from frivolous practices. But other sovereign wealth funds without dividends have also prospered. There have been trade-offs associated with the dividend, some of which have become more obvious with the Alaska economy grappling with the impact of chronic low oil prices. These include foregone earnings, political complexity, income inequality, and the question of public vs. private spending.
Comparative effectiveness of indacaterol/glycopyrronium in the treatment of chronic obstructive pulmonary disease
Authors: Cazzola Mario , Rogliani Paola
Published: August 2017

Indacaterol/glycopyrronium has been the first long-acting β
2
-agonist (LABA)/long-acting muscarinic antagonist (LAMA) fixed-dose combination to be approved as a maintenance treatment in chronic obstructive pulmonary disease patients. Comparative effectiveness studies indicate that it is constantly superior to a LAMA or a LABA alone or even a LABA/inhaled corticosteroid combination, regardless of the drugs used. However, definitive data documenting the benefit of indacaterol/glycopyrronium fixed-dose combination over these consolidated therapies are still absent in a real-world setting, although the results of pivotal randomized controlled trials show that this is the case. Therefore, in addition to the large body of evidence already available supporting the use of indacaterol/glycopyrronium, pragmatic observational studies or
ad hoc
designed trials should be planned to collect data that could confirm the high effectiveness of indacaterol/glycopyrronium even in the real-life clinical practice.
Efecto de dos enraizadores en tres especies forestales promisorias para la recuperación de suelos
Authors: Giraldo C. Luz Adriana , Ríos O Héctor Fabio , Polanco Manuel Francisco
Published: August 2017

La erosión es uno de los principales problemas que afecta los suelos de ladera en el mundo. Algunas de las especies utilizadas en obras de bioingeniería se propagan por medio de estacas, sin embargo no todas enraízan fácilmente, por lo que es necesario utilizar sustancias inductoras de enraizamiento. En este trabajo, evaluamos dos sustancias promotoras de enraizamiento en estacas de mataratón (Gliricidia sepium), nacedero (Trichanthera gigantea) y sauce (Salix humboldtiana). La investigación se realizó en el municipio de Dosquebradas, Risaralda, a una altitud de 1450 m. Los tratamientos consistieron en la aplicación de un enraizador de síntesis (Hormonagro®), un enraizador natural (extracto de Aloe vera) y un testigo sin aplicación de inductores. Los resultados obtenidos indican que para las tres especies es necesario emplear estimuladores de enraizamiento. El extracto de A. Vera produjo un mejor efecto sobre el enraizamiento de las tres especies, siendo más notorio sobre S. humboldtiana, 60 días después de la aplicación. La especie T. gigantea no mostró diferencias significativas con respecto a la aplicación de estimulantes de enraizamiento. En cuanto a la tolerancia de las especies al encharcamiento del sustrato de siembra, S. humboldtiana presentó mayor tolerancia mientras que T. gigantea presento los mayores problemas de pudrición.
Miksi minun piti kirjoittaa juuri ruusuista? Autoritaarisuus, autenttisuus ja autoetnografisuus kirjoittamisessa
Authors: Johanna Pentikäinen
Published: August 2017

My essay seeks to discuss the writing process as a very ambivalent object of study, and I aim to use my own experience as a teacher, researcher, and writer in developing the methods for my study. The discourses of creative writing processes produced in classrooms and in textbooks often emphasise certain aspects of the discovering, selecting, producing and editing phases, while language appears as a medium for a set of activities. However, many professional writers have either stated or mentioned that they have a certain need to write or a set of "writing drives" that enforces and leads them to their activity. These driving aspects of motivation and interest are not easily represented in classroom or textbook discourses, due to their unique and particular nature. I have chosen three terms as a starting point for my study: 1) Authority, because
all writing needs to face the questions of authority, sometimes in terms of scientific or aesthetic authority, sometimes in terms of what can or cannot be said in a certain context; 2) Authenticity, because both research and fiction writing need a sense of lived experience and/or some references to real life in order to remain vital and expressive, and 3) Autoethnography, because it too uses the experienced reality as its starting point, and manifests how transformation from silence to voicing is the real process in writing. I am studying my ideas by combining autoethnographic and explorative narrative voices, and I use my own prose text ”Why write about Roses” as an example of the construction of the voice.
Lohdutusten arkisto (An Archive of Consolation)
Authors: Elina Saloranta
Published: August 2017

This exposition consists of my video piece Voices of Consolation (2014) and my essay "Lohdutusten arkisto" ("An Archive of Consolation"). The video shows interior paintings by the Danish artist Vilhelm Hammershøi (1864–1916). On the soundtrack a group of people are trying to console the black-clad woman seen in the paintings. In the essay I describe the process of making the piece. The essay's structure reflects the video: the text is like an apartment with several rooms.
Collaborative Processes and the Crisis of Attentiveness
Authors: Hanna Kuusela
Published: August 2017

Collaborative artistic processes have become increasingly popular in the past decades. Different forms of community art, relational art, and participatory art, as well as artistic collaborations, and art collectives have occupied a central role in the art world. Does this collaborative taken on art, with its focus on the artistic process, entail a move towards openness and communality, or is it rather an obligation put on us? Is the growing interest in the artistic process a fruitful approach that enriches our understanding of art, or is it an unfortunate sign of art being subordinated to capitalism that pressures us to produce constantly new products, without critical reflection or qualitative criteria? This exposition investigates this dialectics between artistic processes and art objects by following my own research process on collaborative writing.
Hard Times. Lecture Performance as Gestural Approach to Develop Artistic Work-in-Progress
Authors: Falk Hubner
Published: August 2017

Artistic work is often an essential mode of articulation within artistic research, specifically when practice is understood as both source and target domain of the research. Therefore, within the performing arts, both process and product are essential gestures of artistic research and are indeed “justified and critical articulations of an interest in knowledge production."

In this exposition, the format of a lecture performance is investigated and discussed as an explicit articulation through which the process of both artistic work and research is shared, rather than functioning merely as a format for disseminating findings. The format of lecture performance that is investigated here frames the artistic work and theoretical-conceptual framework as two distinct, yet interrelated, processes shared with a conference audience. This includes the deliberate choice for a live performance of artistic work-in-progress, adding a gestural and at times very kinaesthetic aspect to otherwise textually-dominated forms of presentation.

The exposition as such has two focuses that are strongly related to each other, approaching the form of a feedback loop: on the one hand, the creation process of a new experimental performance work by Falk Hübner is investigated. "Hard Times" refers to the title of this artistic work: I will carry you over hard times. The performance itself is part of an artistic research into reduction in music, a continuation of the completed PhD research of the author (Hübner 2014). On the other hand, the lecture performance that employs this artistic work-in-progress as "material" as well as the related discussions with conference audiences is also explored.

The exposition will demonstrate how these conference discussions strongly inform the work process of the specific artistic work in question and attempt to shed an alternative light on the well-known concept of "audience talks", which typically serve to generate feedback and insights into audience perspectives for artists after tryouts or performances of unfinished work. The audiences of conferences are, in most cases, considerably different in nature than "standard" audiences, offering the possibility of insightful input on quite different facets of both artistic work and research process––provoked by the very form of a lecture performance as described above. The exposition suggests that this type of lecture performance, explicitly including the audience at a conference as important source of information, feedback and peer-review, forms a gestural method of artistic research in itself, whose full potential within artistic research is yet to be explored.

Onko instrumentaalisen muutosagendan toteuttaminen poliittisen ja yhteiskunnallisen taiteen ainoa mahdollinen muoto?

Miten voi luoda osallisuuden esityksiä, joissa äänet eivät ole uhrien vaan oman elämänsä täysvaltaisten toimijoiden?
Globalisaation varjoisat huoneet. Liikkuvan kuvan installaatiot eettisen ja poliittisen kohtaamisen tiloina.
Authors: Minna Rainio
Published: August 2017

Väitöskirjaani Globalisaation varjoisat huoneet. Kuulumisen ja ulossulkemisen tilat rajanylityksiä käsittelevissä liikkuvan kuvan installaatioissa (Rainio 2015) pohjautuvassa artikkelissani pohdin miten taide – ja omat installaatiomme – osallistuvat yhteiskunnalliseen keskusteluun kansallisista järjestyksistä, muuttoliikkeistä, rajoista ja globaalista eriarvoisuudesta. Monikanavaiset liikkuvan kuvan installaatiot – jotka olen toteuttanut yhdessä kuvataiteilija Mark Robertsin kanssa – pohjautuvat perusteelliseen taustatutkimukseen ja käsittelevät prostituutioon kohdistuvaa naiskauppaa, pakolaisuutta, siirtolaisuutta ja monikulttuurista suomalaisuutta. Taideteokset ovat syntyneet pyrkimyksestä ymmärtää kansallisuuteen liittyviä kuulumisen ja ulossulkemisen prosesseja ja halusta tehdä näkyväksi ja kuuluvaksi tarinoita yhteiskunnan reunoilta, mitkä usein jäävät kertomatta ja kuulematta.
Drawing Exercises
Authors: Tero Heikkinen
Published: August 2017

In this exposition, I present three different exercises for drawing space and form that have been helpful in analyzing the current state of my drawings and refreshing my abilities. I look at the exercises in terms of skill building, reflective research practice and indwelling.

The study is a process of framing and re-framing drawing through devising drawing tasks for the self. These exercises steer the drawing towards different directions or reinforce the skill. The broader practice of drawing also includes this direction-setting, both building and being aware of a space of possibilities for the drawing practice. Thoughtful drawing exercises can become material for research in the arts.
Kokemuksen symbolit – pohdintoja nuotinnoksen ja soivan välisestä suhteesta
Authors: Pasi Lyytikäinen
Published: August 2017

In my article ‘Symbols of the Experience’, I will approach artistic research through the relationship of a musical idea and the notation of it. How can experimental musical ideas be translated to notation, so that other musicians can understand the notation in a similar way? How does the tradition of notation guide me as a composer? How have workshops with other musicians guided my way of notating music? In this article, I will focus on the relationship between the notation and what is sounding – in general and with reference to my own work.
Tilakokemuksia esitysinstallaatiossa
Authors: Elina Lifländer
Published: August 2017

In this writing, I open up the process of a previous site-specific live installation which I was involved in: Between two skies (2012). This piece is the first part of my doctoral thesis in artistic research, dealing with the spatial experience and the transformation of the scenographer’s working methods. The concept of the event was mainly formed collectively by the discussions and experiments of the working group. In this text, I observe the spatial experience from three points of view: via my own experience, from the perception of the visitors and connecting it to a wider perspective, namely reflecting the nature of the live installation to the art critic Claire Bishop’s thoughts and examples in the book Installation Art, A Critical History (2005) and Anna Moszynska's book Sculpture Now (2013). In the end, I am summing up the kind of impact this process and these three different views have had on my research and how the thoughts and questions have evolved during the preparations.
WIND RAIL - Sort of a Beginning / TUULIKAIDE - Eräänlainen alku
Authors: Annette Arlander
Published: August 2017

In this exposition I present a project called Wind Rail as an example of the beginning of a more extensive artistic research project. The experience of this small experiment in performing landscape led to further explorations almost accidentally.
I am recounting my experiences on Mount Randa and presenting some materials of the first experiments I conducted there. By returning to an old work I ask, whether it contains some abandoned or alternative paths worth returning to. Besides an introduction, which forms the main part of the discussion, the exposition consists of appendixes: videos, sketches for video installations, voice-over texts, documentation of the performance and the paper “Landscape as a View” as well as a conclusion.
VIRTUAALISEN MATERIAN JÄLJILLÄ
Authors: Esa Kirkkopelto
Published: August 2017

Kun esiintyjä esiintyy hänen ruumiinsa käy läpi tietynlaisen transformaation. Tuo transformaatio ei koske vain hänen ulkomuotoaan vaan myös hänen ruumiinsa sisäisyyttä. Ilmiö on sinänsä tuttu kaikille esiintyjille, mutta asiaa ei yleensä tavata tarkastella tähän tapaan. Esiintymisen kokemusta hallitsevat joko erilaiset psykologiset tai tekniset kategoriat, ”psykofyysiikka”. Ekspositio kohdentaa huomion ruumiillisen esillä olemisen kokemukseen sen molemmilta puolilta ja johdattaa havainnoimaan sitä kuinka virtuaalinen materiaalisuus voi ilmetä eri yhteyksissä. Tarkoituksena on etsiä esiintymisen tekniikkaa, joka ei ole enää valjastettu palvelemaan ihmisyksilön selviämistä taidemaailmassa ja yhteiskunnassa.
What calls for thinking?
Authors: Mika Elo
Published: August 2017

My video "Mitä ajattelu kutsuu?" exposed here, audiovisually mimics, translates, challenges and transposes Martin Heidegger's essay "Was heißt Denken?". A compilation of passages of Heidegger's essay, which I have translated into Finnish for this purpose, makes up the voice-over accompanying the images in the video. The exposition also includes these passages in Finnish and German writing. The visual language of the video, in turn, edges Heidegger's pondering out of its focus by turning itself towards a series of questions deriving from the margins and lacunae of the essay. In its own peculiar way, the video is a call for thinking. Further, a text, entitled "conversation" in the menu, addresses some aspects of Heidegger's essay as if seen through the video. The conversation revolves around the questions of language and translation. Its form reflects the density and multifaceted character of the audiovisual material. Finally, "epilogue" attempts at unfolding a question concerning "intelligent design" that arises from the material. Here, my main point of reference is Jean-Luc Nancy's notion of struction.
Experience of Resistance -The Potential of Materiality and Spatiality in Artistic Research
Authors: Riikka Makikoskela
Published: August 2017

The working title of my doctoral research is Relation Between Idea, Means and End in Three-dimensional Art Making. By making art, I study how a three-dimensional artwork evolves. I employ a phenomenological research approach in my practice-led, artistic research.

In this exposition, I present one of the case studies of my dissertation, a sculpture called From A Container to A Room for A Female Elk (2011, porcelain, glazed stoneware, rutile and Ikea table, 70 x 50 x 50 cm). I describe in detail the process of creating this artwork, for it discloses the potential of materiality and spatiality in artistic research: the experience of resistance (Biesta 2012). This phenomenon occurs in my art practice, and I study it from within the same activity. While pursuing three-dimensional artworks, I move both the materials and my own body. In my research, I analyze this aspect of three-dimensional art practice through the phenomenological theory of embodiment. In order to stay close to the experiential, I integrate academic research with the art practice. Only the confrontation with the evolving artwork may reveal the material resistance in this art practice.
Videoteos laatukuvana/ A videowork as a genre picture

Published: August 2017

This exposition consists of a 22-minute video piece, Aamu (Morning, 2013), and an essay titled "Videoteos laatukuvana" ("A videowork as a genre picture"). The video shows a family at breakfast. The essay views the piece as a contemporary genre picture — an interior painting depicting everyday life. The whole process reflects the many different ways in which art history can serve as material for contemporary art. In the text the words, too, take on a special, tangible, material form.
Spacing matters: Alternative Thinking about the Nature of Space
Authors: Monica Raya
Published: August 2017

I would like to present my inter-textual reading of some theories concerning the nature of space and my reflections upon the materiality of it. I aim to open an alternative way to think about scenography. I would like to expose the theoretical process, the visual documentation and the artistic outcomes of a particular scenic event.

So far, I have used my artistic practice as a method of inquiry and it is not my interest to offer an objective approach to the knowledge of space. In my process, I have found that reflective practice has been a central productive mode for my creativity. I intend to evaluate the unintended and unexpected findings in my work, and make them available for other practitioners.
New interpretations of visual culture may contribute to the generation of extended knowledge. New insights about well-known concepts may provoke different outcomes, some of which may go beyond the basic concepts of the discipline of origin.

I am interested in sensuality as an object of analysis and reconsideration of human experience. I am excited to engage with the visual, not simply as a mode of recording data or illustrating texts, but ‘as a medium through which new knowledge and critiques may be created’ (Pink 2007, 13). I propose to connect various sources of knowledge in a way that brings alternatives to think as an architect, as a scenographer, as performance designer and as a teacher.

As much as I would like to situate the outcomes of my artistic research in the field of performance design, I hope my reflections may cross several disciplines.
Groundwater Quality Distribution in Development City between Surakarta-Kartasura (Ground Water Hidrologi System Contemplation in Bengawan Solo Recharge)
Authors: Anna Alif Noor
Published: August 2017

This research is conducted in Kartasura-Surakarta s area especially from an area that relatively does not grow (recharge area) to an area growing to became a city (discharge area). The area is phisiographically restricted by a groundwater contour (i.e. 200 m from sea level) and by three rivers (i.e. Pepe, Wiro, and Bengawan Solo). This research has one objective to know the distribution of groundwater quality in Kartasura-Surakarta that is located between Pepe river and Wiro river. This research uses survey model and description comparative model completed by cheking the field. On the one hand, survey model measures physical data and density population data, and on the other hand, description comparative model is used to know the influence of physical factors and density population factors on groundwater quality. Physical data and density population data collected by using purposive proportional random sampling are analyzed with trend analysis model, statistical analysis model (i.e. parsiil correlation and one-way variant analysis). The result of this research shows that the groundwater quality in the field declines. The trend analysis proves that most of the parameter concentrations of groundwater quality increase from the recharge area to the discharge area. Furthermore, the conclusion is also supported by the result of parsiil correlation analysis that shows a positive correlation between the distance and the most of the parameters, although the positive correlation between the depth of groundwater and the parameters of groundwater quality is weak. Moreover, the results of one-way variant analysis to the selected factors (i.e. geology formation, density groundwater contour, and density population) with the parameters of water quality show that there is a strong difference on the most of the parameters.

Land is natural resources within processing needs to the wise action in order to give good returns for human and being prevented it’s conservation. In the utility of it’s land this land is proper to the agriculture land have sometime emergedthe environment problems, namely the balance of nature is disturbed. It doesn’t mean that land is forbidden to use, but in the it’s utility purposes this land must be considered it’s capability or it’s balance. If form and manner of using this land doesn’t disturb the natural balance, it means to be guaranted. In the countrary, if form and remain to be guaranted. In the contrary, if form and manner of using this land disregard with it’s capability, then the natural balance is disturbed, the land is called asland within dangerous condition or critical land. The coresponding problem that arises in Kecamatan Cepogo under Boyolali district on the surface level land and southern land resembles the critical land that the most erosion appearance can be found assuch sheet erosion, gully erosion, erosion in the other side, vallage forest, settlement land. Mixing estate and the infertile land. This recent exploration purpose is to understand physical factor that affects the critical land as well as to collect and to clarity the critical land. The used method is survey and laboratory analysis by land unit approach ascartography unit. The adopted data of this research is used the effectively width of soil, texture, soil permeability, soil slope, and soil appearance. From this research is understood that the explorated land has three critical land levels, namely; the medium critical land level is 4411,09 are or 17,48%, the wight critical soil level is 7909,74 are or 12,86% of the whole exploration area wide.

Published: August 2017

Kartasura, seen formspace point of view, has special position because it is located in the corridor intersection between Semarang-Surakarta-Yogyakarta. Which becomes three central developing cities in central part of Java. This study is carried out in border town area in east part of Kartasura, which consist of four village – Pabelan, Gonilan, Gumpang, and Makamhaji. That are growing fast due to the effect of urban characteristic from Surakarta. The orientation phenomena of the use of house (OPR), the urban population that led to the commercial use is an interesting fact dealing with the influence of urban activities in those areas. The goal of this study is to know the kindsand the spread of the space of OPR population in east part of Kartasura and the factors, which is studied, is the houses in the research areas and the respondents are the owner of the houses. The sampling uses systematic proportional random sampling. The location of house sample (UMS, UNS, Islamic Boarding Shcool of Assalam), health services (RSIS and RSO), and commercial services (ALFA, UMS stores). All of them are located in Pabelan and Makamhaji. While industrial center consist of PT Tyfountex and small industries around it in Gumpang. Every central activities is divided into two cluster based on the relative distance from central activities (far and near), so as a whole there are four clusters which made up of two clusters in service center and the other in industrial center. Sample at every cluster is taken proportional about 2,5% based on homogenity consideration, whether the selecction of house sampling is taken randomly. The numbers of samples as a whole 175 respondents. The collected data are prensented in the form of frequency and cross table. Qualitative data analysis uses logical thought, deductive induccctive, analogy and comparison, while quantitative data analysis is done using frequency table analysis and cross table. The use of both analysis is sadapted with the data and goal of the study. The result of this study shows that 1) OPR population in east part of Kartasura consist of three kinds, commercial OPR, non commercial, and combination. While the spreading space of the kind of OPR follows the concept of distance decay principle-the nearer relative distance of the house to the center of activities, the more commercial orientation the use of the house is. 2) External factor, which influence OPR, is the developing urban activities such industry, commerce, education, and health instrument. While the internal factor which influence to OPR is the size of land ownership.
Pengaruh Perubahan Penggunaan Lahan terhadap Sifat Biofisik Tanah dan Kapasitas Infiltrasi di Kota Malang
Authors: Utaya Sugeng
Published: August 2017

Land use management causes the changes of the function of the land in the city. The change of the function of uncultivated land to be cultivated land has a potential to change soil biophysical characteristic, and at the same time, it decreases the absorption of soil water. This research aims: (1) to study the influence of the landuse change towards soil biophysical characteristics, (2) to study the correlation between soil biophysical characteristics and infiltration capacity, and (3) to study the influence of the landuse change towards the infiltration capacity. The landuse change is studied by comparing the ongoing mapping documents. Soil biophysical characteristics consist of root biomass, number of worms, soil organic matter (SOM), and porosity. The root biomass is obtained by root density, the number of worms is identified with monolith and hand sorting method, the SOM is identified with fraction analysis, and the porosity is identified with cylinder and pignometer method. The water absorption is measured with the plot experiment. The influence of the landuse towards soil biophysical traits is analyzed T-test and the influence of landuse change towards infiltration capacity is analyzed correlatively. This research gains the results that: (1) the landuse change causes the change of soil biophysical traits, too, and the soil biophysical traits change causes, furthermore, the declining of the land capability in absorbing water, and (2) the amount of the infiltration capacity is caused by soil biophysical traits, mostly by root biomass, number of worms, and the SOM, and (3) the landuse change causes the declining of infiltration capacity.

The purpose of this research is to analyze the potency of land water in the post tectonic earchquake at Merapi slope in Klaten regency, Central Java. This research applies a survey method. The result of analysis is made based on the trilinier diagram, Stiff pattern, and the quality standard of drinking water. The collected data are in the form of land form, shallow land water data, suppressed land water, and well or spring. The results of the sesearch show that 1) the land form in Klaten is divided into four sets of landform, they are peak and slope of volcano, feet of volcano, fluvial palin under volcano, and a set of structural morphology. 2) The potency of land water can be tested based on the amount of land water and the quality of land water. The amount of land water in Klaten regency 260,502,274 m3/year or 727,618,722 liter/day. The amount of land water above is taken from free land water 73,301,436 m3/year, suppressed land water 34,138,520 m3/year, and land water taken from well or spring 153,062,784 m3/year. The quality of shallow land water in Klaten regency is proper to consume. 3) The distribution of upland water potency happens in the feet volcano land form, the potency of medium land water happens in the superficial of fluvial under volcano land form, and the potency of lowland water happens in the slope volcano land form and in the structural range of hills at Bayat subdistrict, 4) The tectonic earthquake gives serious effect toward morphological changes, land split, land subsident and the potency of land water in the fluvial plain of land form under volcano and structural range of hills in the area of Bayat subdistrict, and 5) In 2008, the needs of drinking water in Klaten regency is predicted around 1,164,000 people x 150 liter/day = 174,600,000 liter/day.

Rate of infiltrate can be conduct as function of permeability, suction head and moisture of soil parameter. The parameters have close relationship with soil physical characteristics. That relation can be formulated by empirical research. This study have aim to get typical infiltrate quantity based on land characteristics. Method of Green-Ampt infiltrate developed and used to study typically of infiltrate capacity on Upstream of Watershed (Case on Upstream Cimanuk Watershed). Research conducted use empirical and analytical approach.Study conducted at Oxisol Soil occupied by five kinds of land use. There are 96 soil samples was gathered, taken away from 16 observation points. About 12 parameters of soil physical properties were analyzed to each soil sample. The study covering, development of typical capacities infiltrate pursuant on empiric data at multifarious land characteristics (forest; agro forestry; second crops (palawija); settlement; and non-arable land). The precipitation intensity has been formulated as function of rainy duration and its probabilities. K formulated as function of volumetric water content; rapid drainage pores, and slow drainage pores (K = f (θ, ηc, ηl). Parameter of y, formulated as function of soil moisture (ψ = f (θ)). Parameter of F (T) dummy, formulated as function of p and t; (F (T) Dummy=F (t,p)). So that pursuant to empirical data, rate of infiltrate f (t)) of Green Ampt developed as f (t = f (θ, ηc, ηl, τ, π); and infiltrate cumulative can be calculated by F (F = f (t), t). Infiltrate of every kinds of land characteristics have pattern which much the same to, but differ in its quantity.

Western part of the East Jawa Southern Mountains, which is distributed from Parangtritis, Yogyakarta to Pacitan Bay is the Gunung-Sewu Hills. The carbonate rocks on the Baron-Wonosari transect has some litofacies, and the soils overlying the rocks show some color varieties. Topography of Baron-Wonosari transect can be divided into two areas: southern part (Baron-Mulo) and northern part (Mulo-Wonosari). The southern part is a hilly land, whereas the northern part is a lowland plain. Soils on the southern part are dominated by red soils group, whereas on the northern part dominated by black soils group. The phenomenon is very interesting to be studied. The aim of research was to study relationship of soil colour with topography and pores of underlying carbonate rocks. Methods consist of landform especially topography observation, and soil colour by Munsell Soil Colour Chart, whereas laboratory analysis namely micro porosity and geochemical of carbonate rock. The results showed that micro pores of rocks have no effect to the soil colour formation. However, secondary pores (macro and mega) be suggested influent on red soil formation. Concentration of iron (Fe) and mangan (Mn) elements of carbonate rock have no effect on the formation of soil colour. Topography and rock secondary porosity be estimated have a role as controlling factors on the formation of soil colour by leaching process mechanism. An area, which has a high leaching capacity tend to be found much of red soils, whereas an area which has a low leaching capacity will be formed black soils.

Tendency of land use conversion is followed by maximum discharge of Kreo River, but unknown land use type what which can race improvement of runoff. Purpose of the research is study the relation of rainfall runoff at forest, rice field, and mixed garden. Research about rainfall runoff study is including research type of experiment for purpose of descriptive, through observation of rain data and water level at small watershed with one land use types that is forest, rice field, and mixed garden. Instrument of rain and water level attached at small watershed during the rains 2007.Data analysis comprises analysis of stream hydrograph, rain analysis, stream coefficient, and statistic analysis as well. Big the so small runoff value is more determined by rainfall amounts happened non land use type. Number of big rains at one land use will yield big runoff also, while the same rainfall amounts at some land use types will yield varying runoff follows land use type and condition of soil At small watershed (less than 200 ha), the relation of rainfall (P) with direct runoff (DRO) has very strong correlation (R2 bigger than 0.7). Relation between rain intensity (I) with DRO; I with peak discharge (Qp); duration of rain (DR) with DRO; DR with Qp indicated weak reaction (R2 less than 0.3). It indicated there were many factors (more than 70%) which influenced the above mentioned relations. Runoff coefficient value at forest was 0,3566, mix forest was 0,4227, rice field was 0,6661, and mixed garden was 0,4227. Land ability to permeate in the forest (65%) is bigger than mixed garden (57%) and rice field (33%).
