"ABSTRACTPaddy fields in Northeast Thailand are unusual in that they contain large trees. In recent years, however, in concert with major changes in the agricultural system of Northeast Thailand, including the shift from subsistence to cash crops, mechanization, use of chemical fertilizers, and increased reliance of rural people on manufactured consumer goods, the role of trees in paddy fields has also been changing, leading to a decline in tree densities. This study was conducted in Khok Kwang village, Khon Kaen Province, in order to examine factors influencing variations in density, canopy coverage, and origin of trees in paddy fields there. In recent years, the rate of tree cutting appears to have been increasing and the density of trees declining. This decline reflects many changes in agricultural practices in the village. Farmers now rely on chemical fertilizer rather than litter from the trees to maintain soil fertility. They no longer value any increase in rice yield during dry years in the parts of their helds that are close to the trees because they are now able to pump irrigation water to maintain productivity; and trees are seen as an impediment to the use of four wheel tractors, which have difficulty working efficiently in paddy helds with many trees. In addition, several farmers have begun to plant their paddy Iields with sugarcane, which is less shade tolerant than rice. The density of trees in paddy fields planted with sugarcane (5.7 trees/ha) is much lower than in helds where rice is cultivated (9.6 trees/ha). In upper paddies that are still planted with rice, the trees are retained because they provide valuable goods and services to the farmers and rice yields there are in any case low and unstable. This study illustrates at the micro level how changes in farmer goals, choice of crops, and production technology that are part of the agrarian transformation of Northeast Thailand are reshaping the rural landscape."

ABSTRACTNowadays, the city as the center of driving economic activity has accelerated changes in physical and social aspects of the region. One of the areas of urban administration in Indonesia that experienced rapid development is Palembang City. The high level of trading activities, services, and sport events in Palembang City pushed the local government to develop the development of the new city center and the Jakabaring Sports Complex to accommodate these activities. This development then causes the dynamics of land use in the surrounding area, one of which is the land price. This study tries to analyze the pattern of land price change and the factors that influence these changes such as accessibility and land use as the location aspect and also the status of land rights as legal aspect of the land. The methods used are through secondary data collection, interviews, and validation directly in the field. The analysis is done by overlaying the map of land price changes with land price determinant factors then explained by zone division and using descriptive statistics. The results show that the existence of the Jakabaring Sports Complex triggers a high change in land prices in the surrounding zones. In addition, other factors such as changes in road network connectivity, the percentage of land expansion built, and the coverage of certified land plots is also have an impact on changes in land prices that occur in the research area."

ABSTRACTToll road construction has been carried out and has had an economic impact directly and indirectly, as well as Cipali Toll Road. The high economic activities, the growth of new facilities, and the land use changes around this toll road are signs of new economic ativities. The new economic activity centers has increased the land price in the surrounding area. The objective of this study is to determine the land use price changes at the Cipali Toll Road and understand the factors that influence it, namely the economic activity, distance from toll road gate, land status and land use. Data were colllected by interviewing key informants from the formal agencies and the communities as well. Using overlay technic between land price changes and factors that influence it, the result shows that land price changes did not happen in all areas around the toll road in the same way. Changes in land price also vary. The dominant factor that influence land price changes is distance from the toll road gate. Land price changes mainly occur in areas dominated by built up areas or areas that been dominated by economic facilities. Land status has no effect on land price changes. This result were support by Pearson Product Moment analysis, one way annova, and linier regression. The conclusion of this study showed that land price changes influence by distance from the toll road gate and economic activity center."

"ABSTRAKArmed conflicts create drastic socioeconomic shocks that lead to land use and land cover changes in ways that are not yet well understood. Several studies have used satellite imagery to detect such changes during periods of conflict. However, there has been an insufficient examination of older conflicts before the 1970s. By examining older conflicts, we can examine the effects of conflict on land use and land cover over a long time span. This study reveals land use and land cover changes during the Second Indochina War (1960-75) and the wars immediate and long-term effects on land use and land cover by combining an analysis of aerial and satellite photographs with fieldwork. This study concludes that the war created an abnormal situation in which a large number of people from a different ethnic group came to live amongst the original inhabitants of the research site. This led to a unique farming landscape and vast areas of forest destruction. The study also reveals that forest destruction during the war was a significant milestone in the history of the vegetation of the research site, and the vegetative landscape has still not recovered to its prewar condition. These findings, as well as the results of previous research, suggest that we need to be more conscious of the effects of war on forest degradation in Laos."

"Infiltrasi merupakan fenomena aliran air dari atas tanah ke bawah permukaan. Penelitian ini ditujukan untuk menganalisis laju infiltrasi pada empat jenis tutupan lahan, yaitu di Sawah (SW), Pemukiman (PM), Pertanian Lahan Kering (PLK), dan Pertanian Lahan Kering Campur (PLKC), di daerah Rancamulya, Bandung. Dengan menggunakan double ring infiltrometer dan metode Horton, diperoleh hasil klasifikasi laju infiltrasi yang terbagi menjadi empat kelompok, yaitu sedang, agak cepat, cepat, dan sangat cepat. Stasiun PM-1 memiliki nilai laju infiltrasi konstan terbesar dengan nilai 600 mm/jam, sedangkan SW-2 memiliki nilai terkecil yaitu 48 mm/jam. Perbedaan yang signifikan ini dipengaruhi oleh perbedaan nilai kadar air PM-1 yang hanya 21,2%, sedangkan pada SW-2 sebesar 71,4%. Pengujian selanjutnya dilakukan dengan metode regresi sederhana untuk melihat pengaruh sifat fisika tanah terhadap laju infiltrasi. Hasilnya menunjukkan bahwa urutan sifat fisika tanah yang paling berpengaruh berdasarkan nilai koefisien korelasi adalah kadar air (0,996), ruang pori total (0,737), dan bobot isi (0,679). Selanjutnya, dilakukan analisis terhadap peta klasifikasi laju infiltrasi berdasarkan jenis tutupan lahan. Kesimpulan yang diperoleh adalah variasi laju infiltrasi dapat terjadi bahkan pada satu jenis tutupan lahan yang sama, seperti pada jenis tutupan lahan pemukiman.

Infiltration is the phenomenon of water flow from above the ground to below the surface. This study aimed to analyze the infiltration rate in four types of land use: Rice Field, Residential Area, Dry and Mixed Land of Agriculture, in the Rancamulya area, Bandung. The infiltration rates were collected by using a double ring infiltrometer and the Horton method, and it was classified into four groups: moderate, moderately rapid, rapid, and very rapid. PM-1 has the largest constant infiltration rate with a value of 600 mm/hour, while SW-2 has the smallest value of 48 mm/hour. This significant difference is influenced by the difference in the water content of PM-1 which is only 21.2%, while in SW-2 is 71.4%. The next test was carried out using a simple regression method, and the results show that the order of the most influential soil physical properties towards infiltration rate based on the coefficient of correlation is water content (0.996), total pore space (0.737), and bulk density (0.679). Based on the map, it can be concluded that variations in infiltration rates can occur even in the same type of land use, such as residential land."

Gold Mine And Galena Mountain Region Bolang Cigudeg District of Bogor

Regency. This research was conducted with qualitative research methods and

approaches to the study of documents, observations and interviews relating to the

Conflict Potential Gold Mine Land Use And Bolang Galena Mountain Region,

between 2000 to 2014, Based on research findings, the factors that influence the

presence of conflicts occur due to dissatisfaction with the local community against

the company due to the seizure of land from the public, Environmental

destruction, land compensation is not yet complete, the system of recruitment of

employees by companies that declared nepotism, as well as the existence of illegal

mining / mining region Gurandil always lead to a potential conflict is not there are

rules that can facilitate and oversee their interests to meet the economic needs of

their families. Then the CSR program of community development or mining

company that is not running properly, thereby increasing antipathy of the public

against the company. Statutory system that overlap will cause new problems

diarea mining region. This study has been able to map the actors in the conflict is

between: (1). Local communities versus mining companies get the KSO and the

right of KP by Perhutani KPH Bogor Party (2). Conflict between illegal mining /

Gurandil versus mining companies. (3). conflicts among PETI / Gurandil that

occur due to friction caused by the seizure of gold veins, (4). Government officials

and NGO Walhi Versus. Conflict resolution is implemented as follows: (1) The

Parliament Bogor mediation with the mediator, (2) Public Land compensation fee,

(3) Mine Land Reclamation. These activities still leaves problem because the

number of people who are not satisfied and feel aggrieved. The conflict has the

potential to threaten the Environment and Regional Resilience."

"Urbanisasi merupakan fenomena perubahan pola pemukiman manusia yang dapat dipercepat dengan adanya aksesibilitas dapat mempermudah terjadinya ekspansi penduduk dari perkotaan ke pinggiran kota serta mempermudah mobilitas penduduk menuju pusat kegiatan. Namun adanya pusat kegiatan dan aksesibilitas yang baik akan mendorong semakin tingginya permintaan terhadap tempat tinggal sehingga mempengaruhi nilai tanah yang berada disekitarnya serta terjadinya perubahan sektor pekerjaan dari pertanian menjadi non pertanian, hal ini dapat memotivasi petani pertanian padi untuk melakukan perubahan penggunan lahan dari pertanian ke pemukiman baik pada wilayah urban maupun rural. Penelitian ini bertujuan untuk menganalisis motivasi petani terhadap fenomena perubahan penggunaan lahan yang dilakukan oleh petani pada wilayah rural dan urban serta menganalisis perubahan pendapatan rumah tangga pertanian dari pengaruh perubahan penggunaan lahan. Untuk menganalisis variabel-variabel yang dapat memotivasi petani dalam melakukan perubahan penggunaan lahan di wilayah urban dan rural digunakan analisis deskriptif. Hasil dari penelitian ini adalah petani pada wilayah urban dan rural telah mampu memenuhi kebutuhan dasar sehingga motivasi melakukan perubahan penggunaan lahan adalah karena ajakan petani lain, akan tetapi petani yang mengubah lahan pertaniannya disebabkan oleh motivasi finansial dan petani yang masih berkeinginan untuk bertani menyebabkan pemindahan lokasi sawah. Perubahan penggunaan lahan juga menurunkan pendapatan petani 50% di wilayah urban dan 60% di wilayah rural.

Urbanization is a phenomenon of changes in human settlement patterns that can be accelerated by accessibility, which can facilitate population expansion from urban to suburban areas and facilitate the mobility of residents to the center of activity. However, the existence of an activity center and good accessibility will encourage higher demand for housing so that it affects the value of the surrounding land and changes in the employment sector from agriculture to non-agriculture, this can motivate rice farming farmers to change the land use from agriculture to settlements. both in urban and rural areas. This study aims to analyze the motivation of farmers to the phenomenon of land use changes carried out by farmers in rural and urban areas and to analyze changes in agricultural household income from the effects of land use changes. To analyze the variables that can motivate farmers in making changes to land use in urban and rural areas, descriptive analysis is used. The result of this study is that farmers in urban and rural areas have been able to meet their basic needs so the motivation to change land use is due to the invitation of other farmers, but farmers who change their agricultural land are due to financial motivation and farmers who still want to farm cause relocation of rice fields. Changes in land use also reduce farmers' income by 50% in urban areas and 60% in rural areas."

"Sungai Ciliwung merupakan salah satu sungai di Pulau Jawa yang tercemar oleh limbah dari aktivitas rumah tangga, komersial/industri serta pertanian. Pesatnya pertumbuhan penduduk akan memicu adanya perubahan tata guna lahan. Seiring dengan pertumbuhan penduduk dan perkembangan aktivitas manusia di berbagai sektor, pencemaran air sungai menjadi masalah serius yang dihadapi oleh manusia. Tujuan dari penelitian ini adalah untuk melakukan analisis spasiotemporal terhadap konsentrasi dan beban pencemar air Sungai Ciliwung serta korelasinya dengan tren perubahan tata guna lahan untuk mengetahui faktor-faktor dominan yang memengaruhi beban pencemaran sungai tersebut. Analisis dilakukan terhadap parameter pencemar organik dan nutrien (BOD, COD, DO, TSS, NH3, NO2, NO3 dan Total Fosfat) dengan menggunakan data debit dan kualitas air Sungai Ciliwung dari BBWS Ciliwung – Cisadane. Secara spasial, konsentrasi dan beban pencemar organik dan nutrien dari hulu ke hilir cenderung menunjukkan peningkatan dari hulu hingga ke hilir. Sedangkan secara temporal, konsentrasi pencemar organik (BOD dan COD) memuncak di tahun 2018 kemudian mengalami penurunan hingga tahun 2020. Kemudian, konsentrasi pencemar nutrien (NH3, NO3, T-P) dan TSS paling tinggi adalah pada tahun 2020. Tren beban BOD, NH3, NO2dari tahun 2016 – 2020 meningkat, sedangkan tren beban COD, TSS, NO3, dan Total Fosfat dari tahun 2016 – 2020 menurun. Bila dilihat dari tren perubahan tutupan lahan dan nilai koefisien korelasi, peningkatan persentase lahan permukiman menyebabkan meningkatnya beban pencemar. Hal tersebut ditunjukkan dari hasil uji korelasi yang positif kuat-moderat antara keduanya. Sedangkan hasil uji korelasi persentase lahan pertanian dengan beban pencemar menunjukkan korelasi negatif moderat dengan lahan pertanian. Dari hasil uji tersebut dapat diperkirakan bahwa limbah aktivitas pertanian secara kuantitas tidak lagi signifikan terhadap pencemaran di badan air bila dibandingkan dengan kegiatan domestik. Selain itu, rata-rata rasio BOD/COD didapatkan kurang dari 0,3 (bersifat non-biodgradable) sebagai indikator adanya pencemaran dari kegiatan non-domestik seperti kegiatan komersil/industri dan TPA. Hasil penelitian menunjukkan bahwa aktivitas antropogenik yang paling dominan memengaruhi beban pencemar organik dan nutrien di DAS Ciliwung dalam penelitian ini adalah kegiatan domestik (secara khusus akibat limbah greywater), serta limbah kegiatan komersil/industri yang tidak memenuhi standar yang ditetapkan namun langsung dibuang ke saluran air dan mengalir ke badan air.

Ciliwung River is one of many rivers on the Java Island which is polluted by waste from domestic, commercial/industrial and agricultural activities. The rapid population growth caused changes in land use. Along with population growth and the development of human activities in various sectors, river pollution became a serious problem for humans. The purpose of this study is to conduct a spatiotemporal analysis of the concentration and pollutant load of the Ciliwung River and its correlation with the trend of land use changes to determine the factors that dominantly influence the river pollution. The analysis was carried out on the parameters of organic pollutants and nutrients (BOD, COD, DO, TSS, NH3, NO2, NO3 and Total Phosphate) using the flow and water quality data of the Ciliwung River from BBWS Ciliwung – Cisadane. Spatially, the concentration of organic pollutants and nutrients increased from upstream to downstream. Spatial variations in organic and nutrient pollutant loads also tend to show an increase from upstream to downstream. Meanwhile, temporally, the concentration and load of organic pollutants (BOD and COD) peaked in 2018 and then decreased until 2020. Then, the concentration and load of nutrient pollutants (NH3, NO3, T-P) and the highest TSS was in 2020. The trend of BOD, NH3, and NO2 loads from 2016 – 2020 increased, while the trend of COD, TSS, NO3, and Total Phosphate loads from 2016 – 2020 decreased. From the trend of land cover changes and the value of coefficient correlation, an increasing percentage of residential land caused an increasing pollutant load. This is indicated by the results of a strong-moderate positive correlation test between those two. While the results of the correlation test of the percentage of agricultural land with the pollutant load showed a negative correlation. From that results, it can be estimated that the waste of agricultural activity is no longer significant in terms of pollution in water bodies compared to domestic activities. In addition, the average BOD/COD ratio was found to be less than 0,3 (non-biodgradable) as an indicator of pollution from non-domestic activities such as commercial/industrial activities or landfill runoff. The results showed that the most dominant anthropogenic activities affecting organic and nutrient pollutant loads in the Ciliwung watershed in this study were domestic activities (particularly due to greywater waste), as well as the waste of commercial/industrial activities that did not meet the established standards but were directly discharged and flowed into a water body."
