"ABSTRAKPhosphorus is an essential element for living organisms. However, an excess loading of phosphorus produces undesirable eutrophication in water bodies. However, different phosphorus species play different roles in the bioavailability and geochemical cycling of phosphorus in the water column. Few studies on the abundance and form of particulate phosphorus have been conducted in Thailand. This study investigated the abundance of particulate phosphorus, in both organic and inorganic forms, in the Mae Klong river, Thailand. The variation in abundance of particulate phosphorus and its form were examined. Low Total Particulate Phosphorus (TPP) concentrations were found upstream, with two TPP peaks at the MK7 and MK10 stations, which are located near urban areas. Within the TPP pool, Particulate Organic Phosphorus (POP) was the dominant form of particulate phosphorus at eight sampling stations, whereas Particulate Inorganic Phosphorus (PIP) was the dominant form at four sampling stations. The high proportion of POP in the TPP pool and strong relationship between TPP, POP, and chlorophyll a suggested that phytoplankton was a source of particulate phosphorus in the Mae Klong River. Our findings on the abundance and chemical speciation provide a better understanding of the cycle of this bioactive element and, will support the establishment of water management and regulation in the Mae Klong River."

"Mae Teang District is home to many tributaries of the Ping River. Each tributary is associated with different geographical characteristics and uses. This study is the first report on benthic diatom diversity in the designated water bodies and the first comparison of benthic diatom distribution in the Ping River and its tributaries, including the Mae Hao and Mae Luang Streams in Mae Taeng District of Chiang Mai Province, Thailand. The benthic diatom distribution and physico-chemical properties were investigated in August and November 2015 at three locations in each water body. The highest abundance of benthic diatoms was found in the Ping River (143 species), followed by Mae Hao (132 species) and Mae Luang Streams (90 species). The most abundant species found in the Ping River were Planothidium lanceolatum, Nitzschia palea, Navicula cryptotenella and Seminavis strigosa. The most abundant species found in the Mae Hao Stream were Nitzschia palea, Seminavis strigosa, Surirella splendida and Sellaphora pupula. The most abundant species found in the Mae Luang Stream were Navicula cryptotenella, Diadesmis contenta, Karayevia oblongella and Achnanthes brevipes. Additionally, Amphipleura lindheimeri Grunow was identified as a newly recorded species for Thailand. This study revealed that the Ping River and Mae Hao Stream are similar bodies of water when compared with the Mae Luang Stream in terms of benthic diatom diversity and water quality. In addition, indicator species of tolerance and sensitivity to organic pollution were found. In conclusion, the areas of utilization were found to have affected the distribution of benthic diatoms in these water bodies, along with the water quality of the Ping River and its tributaries."

"Litter production is one of the major nutrient enrichments in a mangrove forest. Investigation on nutrient components in litter will lead to evaluation of nutrient accumulation. Therefore, this research aimed to 1) evaluate litter production in tropical mangrove forest at Klong Khone, Samut Songkhram province, Thailand; 2) investigate carbon, nitrogen and phosphorus contents in litter; and, 3) observe sediment quality and existing mangrove condition in the study area. Litter and sediment were collected at Klong Khone, Samut Songkhram province in September-October 2015. Litter samples were analyzed for biomass production, and composition of carbon, nitrogen and phosphorus. Sediment samples were analyzed for pH, salinity, water content, grain size composition, organic carbon, total nitrogen and total phosphorus. Results showed that leaf, branch, and fruit litter production were 65.02, 47.94 and 19.03 g DW/m2/month, respectively. Carbon, nitrogen, and phosphorus content in the litter were 20.36, 0.37 and 4.47 mg/g DW leaf litter, respectively. The value of pH, salinity and water content of sediment ranged from 6.66-7.50, 3.30-9.28 ppt and 52.24-69.65%, respectively. Sediment was composed of fine sand (0.125-1 mm) 7.68%, silt (0.06-0.125 mm) 6.13%, and clay (smaller than 0.06 mm) 86.19%. By using statistical analysis (t-test), results showed no difference of all parameters between months. However, during the research, it was found that organic carbon decreased 2.37 mg C/g DW sediment; meanwhile nitrogen and phosphorus increased 0.44 mg N and 0.12 mg P /g DW sediment, respectively. Finally, carbon, nitrogen and phosphorus accumulation by litterfall were found to be 1877, 34 and 734 mg/m2/month, respectively. These results will help in clarifying nutrient dynamic pathway by mangrove trees which play an important role in coastal and estuarine ecosystem restoration."

"The groundwater problem at Mae Moh mine has drawn attention as the mining excavation goesdeeper, thus resulting in detailed investigation of hydrogeological condition. One of the problemsfacing the mining is floor heave influenced by groundwater. The control of groundwater pressure indeep-seated aquifers with high elevation becomes important in the mining. In addition, theunderground water at Mae Moh mine is naturally contaminated by arsenic. Therefore, thedevelopments of 3D groundwater model of deep pit mine using Modflow simulation and thestudies of underground water treatment are needed for the future planning. The predictivesimulations were carried out for eight years (2007 to 2015). Because stability of the Mae Moh mineshows how can be closely linked to the water environment, this paper aims to report the field Visitsto the water related facilities of the mine, which were conducted during 2010-2013. The resultreveals that the potentiometric head level is strongly increased, which might be a potential risk forthe floor heave; thus, depressurization is required. Field measurements reveal pH level at 8 and arange of total dissolved solid (TDS) at 870-2020 ppm. Treatment efficiency shows that more than95% of the arsenic can be successfully removed using ferric chloride."

"ABSTRACTThis study was to determine albuminuria prevalence and risk associations of albuminuria in people who lived in Klong Luang community. This cross-sectional study was conducted in Klong Luang community, Pathum Thani province, Thailand. The mid-stream urine and blood samples were collected from all participants for albuminuria testing with urine strip and blood urea nitrogen and creatinine analysis, respectively. Binary logistic regression was used for risk association analysis. Among 239 participants enrolled, 32 (13.4%) subjects had albuminuria. Creatinine was a significantly independent risk association for albuminuria (p<0.045, α=0.05). Participants who lived in this community were 13.4% albuminuria prevalence and creatinine was an independent risk association for albuminuria. Thus, Primary Health Care Services should follow up subjects with albuminuria and provide health education program to the Klong Luang community."

"Identitas merupakan suatu hal yang cair, situasional, dan dapat dinegosiasikan. Indonesia merupakan negara yang dihuni banyak etnik di dalamnya. Sebelum berdirinya negara-bangsa bernama Indonesia, etnik-etnik yang mendiami wilayah nusantara telah eskis. Mereka etnik memiliki ciri, tradisi dan keunikan masing-masing. Menurut data terbaru 2016 jumlahnya dari Sabang sampai Marauke sekitar 700-an etnik dan subetnik. Skripsi ini akan mengkaji kontestasi identitas sekelompok pelajar asal Indonesia yang sedang sekolah di Universitas Mae Fah Luang MFU, Chiang Rai, Thailand pada kurun November 2016 mdash Februari 2017. Keberagaman identitas etnik di dalam kelompok pelajar Indonesia yang menamakan diri sebagai PERMITHA Perhimpunan Mahasiswa Indonesia simpul MFU mdash;memberikan warna dalam mosaic kebudayaan Indonesia. Setiap hari mereka berinteraksi dengan orang-orang yang memiliki pemahaman terbatas mengenai orang Indonesia, dan budaya Indonesia. Mereka berada di ruang-waktu space yang mengharuskan mereka untuk melakukan peralihan identitas etnik, nasional dan transnasional.

Identity are fluid, situational, and negoitable. Indonesia is a home for many ethnics. Before Indonesia was established as a nation state, those ethnics already exist. They ethnics have their unique tradition and way of life. Based on the newest source 2016 , there are from Sabang mdash Marauke about 700 ethnics and subethnics. This thesis will criticize the concept of Indonesia as identity, moreover its contest to their ethnic identities of Indonesian student group while they have studied at Mae Fah Luang University MFU , Chiang Rai, Thailand during November 2016 mdash Februari 2017. The diversities of ethnic identity group is called PERMITHA Indonesian Student Group Association that gives their variety in Indonesias cultural mosaic. Generally, they interact each other, yet has no idea about Indonesian and ldquo Indonesian culture. They were in the space which force them to switch their ethnic, national and transnational identity."
