The grain grinding business unit is needed by the farmer to process the harvest but also in particular, it creates air pollution from its dusty materials. The worker or operator has a potential risk of being contaminated by the dusty materials and lungs vital capacity reduction. This research is aimed to analyze the effects of the grain grinding polluting dust to wards the lungs vital capacity of workers at Abiansemal in Badung District. This research is sort of an analytical observation with cross sectional design. The number of chosen samples is 32 workers with a total sampling method among 16 grain grinding business units. The data resources is a primary data which obtained using questionnaire, the measurement and observation include: the worker's characteristic (working term, age, and height), dust value, breath frequency and lungs vital capacity. The data is analyzed using regression statistic. The result of the research indicates that the amount of dust at the grain grinding business unit is around 10,0079-11,6151 mg/m3, working term is one to 44 years, age 22-62, and height 155-175 cm, the condition of the grinding room is 93,75% does not meet the ventilation standard, 100% is not provided with dust control tool, 97,75% does not provide mask and 93,75% is situated in a housing are. The conclusion of the research is that dust level, working term and height in particular has a significant correlation with lungs vital capacity (p < 0,05) but age does not have a significant correlation with the workers lungs vital capacity (p> 0,05). The higher level of dust makes the higher lungs vital capacity reduction, the longer working term makes the lower lungs vital capacity and the taller of workers height .indicates the higher workers lungs vital capacity. The impact of dusty materials of grain grinding business unit towards the workers is the decreasing of workers lungs vital capacity by the disorder of lungs restriction function ( 65,62%). It is suggested to the business owner to conduct technical controls. Workers are strongly recommended to put on mask, have sufficient nutrition supplies and workers with the age over 40 years should not work in j:his area. For the health department of Badung District should implement any efforts of K3, and for other relevant departments which take a part in giving recommendation must consider a requirement to make it outside the housing area.

Wisata terumbu karang sangat diminati oleh wisatawan dalam negeri maupun manca negara. Pulau Menjan gan dan Nusa Penida merupakan salah satu lokasi wisata yang yang sangat diminati karena memiliki ekosistem pesisir seperti terumbu karang, hutan bakau, rumput laut dan lain-lain memiliki kekayaan yang beranekaragam. Dalam penelitian ini, data satelit ALOS (AVNIR-2) yang memiliki 3 spektrum tampak yang digunakan untuk mendeteksi daerah penyebarannya. Tujuan penelitian ini adalah: 1) Untuk mengetahui sebaran terumbu karang secara umum di Pulau Men jangan dan Pulau Nusa Penida dan 2) Untuk mengetahui perubahan terumbu karang di Pulau Menjangan dan Pulau Nusa Penida. Akurasi yang baik (Nusa Penida 81,213% (2007), 80,334% (2009), Menjangan 85,555% (2007), 84,285% (2009)) diperkirakan karena sebagian besar daerah pelatihan sesuai dengan data lapangan. Akurasi dari citra satelit tanpa metode Lyzenga di Nusa Penida Island itu lebih rendah dari keakuratan citra satelit di Pulau Men jangan. Hal ini disebabkan oleh 3 faktor-faktor seperti kesalahan klasifi.kasi sesuai dengan interaksi kompleks dari tata ruang topografi, informasi kesalahan definisi dari kelas spektral dan kesalahan pada citra satelit itu sendiri. Hasil persebaran Pulau Menjangan menunjukkan luasan tutupan terumbu karang 49,04 hektar pada tahun 2009 dan 51,06 hektar pada tahun 2007 dengan perubahan luas terumbu karang meliputi 2102 hektar tingkat persentase 3,95%. Nusa Penida menunjukkan luasan tutupan terumbu karang 399 66 hektar pada tahun 2009 dan 339,65 hektar pada tahun 2007 dan , perubahan cakupan terumbu karang 60.01 hektar tingkat presentase 17,6%. Penurunan terumbu karang di pulau menjangan terjadi karena seperti suhu, serangan predator, gelom bang besar dan aktivitas manusia. Terutama pada suhu tinggi yaitu 30° pada Nopember 2001, Desember 20021 Desember 2006, Desember 2007, November 2008, April 2009, April 2010 dan Desember 2010 Suhu yang tinggi tampaknya memberikan kerusakan besar terhadap terumbu karang sehingga terjadi pemutihan terumbu karang. Peningkatan terumbu karang di nusa penida karena dipengaruhi oleh suhu perairan di Nusa Penida yang optimal bagi pertumbuhan karang.

The study location of landslide is in Hokkaido, Japan which occurred due to the Iburi Earthquake 2018. In this study the landslide has been estimated by the fully Polarimetric SAR (Pol-SAR) technique based on ALOS-2 PALSAR-2 data using the Yamaguchi’s decomposition. The Yamaguchi's decomposition is proposed by Yoshio Yamaguchi et.al. The data has been analyzed using the deep learning process with SegNet architecture with color composite. In this research, the performance of SegNet is fast and efficient in memory usage. However, the result is not good, based on the Intersection over Union (IoU) evaluation obtained the lowest value is 0.0515 and the highest value is 0.1483. That is because of difficulty to make training datasets and of a small number of datasets. The greater difference between accuracy and loss graph along with higher epochs represents overfitting. The overfitting can be caused by the limited amount of training data and failure of the network to generalize the feature set over the training images.

This study was conducted at the Village of Delodbrawah, Jembrana Regency, Bali. It was aimed to know the managementpattern available at the Village of Delodbrawah, the effect of maintenance to the water quality of shrimp pond and river, vegetationcondition and river biota. The study was conducted for approximately 3 months in each pond starting from January up to May 2007.Shrimp ponds found in the Village of Delodbrawah use intensive and semi intensive management with open system where thechange its water maximaly from well and river. Semi intensive pattern used vitamin C as a mixture of food and the intensive one usedgarlic (Allium sativum L) as antibiotic. The use of natural antibiotics can increase the age of the shrimps up to 96 days before it washarvested. While the one using other probiotics, the age of the shrimps was 88 – 90 days shorter after it was harvested.The data of water quality showed that pond 1 that used intensive system had more stable water quality parameter and supportthe culture compared with other blocks. At the end of the culture of PO4 and NO2 tends to increase blooming plankton such asChlorella sp, Oscillatoria sp, Cyclotella sp. But it did not affect the quality of river water which was still under the threshold ofstandard quality of water class III Government Regulation of the Republic of Indonesia Number 82 of 2001 concerning theManagement of Water Quality and Water Pollution Control.Vegetation around the shrimp ponds were dominated by Nipah (Nypa fruticans Wurm) in the location nearing the river estuary.From the production data pond 1 had the best production, related to the nipah functioning as bioremediator of surrounding waters.The other location is near palawija plants. The most prominent river biota is kijing (Bivalvia) which looked bigger and many innumbers in the location where there are two disposal channels, pond disposal and agricultural channel that transports higher organicsubstance to be disposed to the river. Affectiveness of the intensive pond management optimally produces the oldest age of 96 days, the harvest of 3,964 – 4,271kg/1500 m2, Survival Rate (SR) of 98% and Feed Convertion Ratio (FCR) of 1,32

Rice crop is one of the important commodities that must always be available, so estimation of rice production becomes very important to do before harvesting time to know the food availability. The technology that can be used is remote sensing technology using Landsat 8 Satellite. The aims of this study were (1) to obtain the model of estimation of rice production with Landsat 8 image analysis, and (2) to know the accuracy of the model that obtained by Landsat 8. The research area is located in three sub-districts in Klungkung regency. Analysis in this research was conducted by single band analysis and analysis of vegetation index of satellite image of Landsat 8. Estimation model of rice production was developed by finding the relationship between satellite image data and rice production data. The final stage is the accuracy test of the rice production estimation model, with t test and regression analysis. The results showed: (1) estimation of rice production can be calculated between 67 to 77 days after planting; (2) there was a positive correlation between NDVI (Normalized Difference Vegetation Index) vegetation index value with rice yield; (3) the model of rice production estimation is y = 2.0442e1.8787x (x is NDVI value of Landsat 8 and y is rice production); (4) The results of the model accuracy test showed that the obtained model is suitable to predict rice production with accuracy level is 89.29% and standard error of production estimation is + 0.443 ton/ha. Based on research results, it can be concluded that Landsat 8 Satellite image can be used to estimate rice production and the accuracy level is 89.29%. The results are expected to be a reference in estimating rice production in Klungkung Regency.

The objective of this article is to examine the ethnoecological study of "Satoyama" and to present in the form of descriptive case study approach and literature approach to collect reading materials which related in this object through the website of internet and some books. The meaning of Satoyama is the mountains near the village. The mountains are put in the ecosystem that is influenced by the life of the communities. Actually, since 5000 years ago inhabitant of Japan already knew and maintained their forests in harmony. They lived around the fields near the rivers. Approximately 2000 years ago they began to plant rice in their field. Harmonious relationship between humans, forests, land and water ran from year to year in tradisional ways, they utilized the environment as wise as they could. Such conditions made Satoyama as traditional wisdom of use. Due to population growing forest conditions gradually began to change. The forest encroachment and logging for building materials of the giant castles and fuel wood destroyed forest in Japan widely. With the development of science and technology the economic value of forest in Satoyama have been influenced negatively. In short since the early 1960s years Satoyama has no economic value anymore and the traditional wisdom Satoyama society began to fall down, so the economical thinking take precedence because the rapid growth of population and development science and technology. At this time many Satoyama areas have been changed shape and it has been converted to land for housing development on a large scale into the "New Town" by the big city like; "Senri New Town'' area of Northern Osaka "Tama New Town" area of Western Tokyo "Senboku New Town'' area of Southern Osaka
