Abstract. We analyze distributions of rain-event sizes, rain-event durations, and dry-spell durations for data obtained from a network of 20 rain gauges scattered in a region of the northwestern Mediterranean coast. While power-law distributions model the dry-spell durations with a common exponent 1.50 ± 0.05, density analysis is inconclusive for event sizes and event durations, due to finite size effects. However, we present alternative evidence of the existence of scale invariance in these distributions by means of different data collapses of the distributions. These results demonstrate that scaling properties of rain events and dry spells can also be observed for medium-resolution rain data.

Abstrak Telah dilakukan penelitian tentang pengaruh El Nino Terhadap Hujan di NTT yang terdiri dari 23 Zona Musim dan dianalisis berdasarkan data Curah Hujan tujuh tahun terakhir kejadian El Nino terhadap data Normal selama 30 tahun. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh El Nino terhadap Awal Musim Hujan, Periode Musim Hujan, Panjang Musim Hujan, Curah Hujan Musim Hujan dan Sifat Hujan. Metode yang digunakan dalam penelitian ini adalah metode komparatif atau perbandingan dan Analisis Curah Hujan tahun El Nino  pada tujuh kali kejadian terhadap Normal Hujan selama 30 tahun. Hasil yang diperoleh dari penelitian ini adalah pada tahun terjadi El Nino, sebagian besar ZOM di NTT  dengan Awal Musim Hujan lebih mundur dari Normal, Periode Musim Hujan lebih pendek dari Normal serta Curah Hujan berkurang dari Normal dan Sifat Hujan menjadi di Bawah Normal. Pengaruh kejadian El Nino terhadap Awal Musim Hujan yang lebih mundur dari Normalnya, Periode Musim Hujan yang lebih pendek dari Normalnya dan Sifat Hujan yang di Bawah Normal dari 23 Zona di NTT pada tahun-tahun kejadian El Nino bervariasi dan ZOM yang dipengaruhi kejadian El Nino tidak tetap. Kata kunci : El Nino, Awal Musim Hujan, Periode Musim Hujan, Sifat Hujan. Abstract [Analysis Of The Influence Of El Nino On Rain In NTT] Studies have been conducted about the influence of El Nino on Rain the province which consists of 23 Zones the Season and analyzed based on Rain data for the last seven years the incidence of El Nino against Normal data for 30 years. The purpose  of this studyis to determine the effect of El Nino to the Beginning of the Rainy Season, Long Rainy Season, Precipitation of the Rainy Season and the Nature of the Rain. The method used in this research is the comparative method or comparison and Analysis of precipitation is the year of El Nino on the seven times genesis against the Normal Rain for 30 years. The results obtained from this research is that in the event of El Nino, most of the ZOM in NTT with the Beginning of the Rainy Season is more bacward than Normal, the Period of the Rainy Season is horter than Normal and precipitation is reduced from the Normal and the Nature of Rain to be Below Normal.this is because in the event of El Nino, monsoons coming from the Southest bring the water vapor that a lot of most of the turn toward the coast of Peru. The influence of El Nino to the Beginning of the Rainy Season which is backwards from Normal, the Period of the Rainy Season is shorter than Normal and the Nature of the Rainfall Below Normal from the 23 Zones in the province in the years of El Nino are varied and ZOM that influence the incidence of El Nino is not fixed. Keywords: El Nino, the Beginning of the Rainy Season, the Period of the Rainy Season, the Nature of the Rain

The widespread drought area in Trenggalek Regency in 2019 needs to be analyzed to reduce negative impacts and as a monitoring tool to anticipate future drought events. The Standardized Precipitation Index (SPI) is a drought analysis method by calculating the rainwater deficit at various time scales used to identify the distribution of drought in Trenggalek Regency. This study using rain data on 13 rain stations for the period 1990-2019 and agricultural production data for 2019. The calculation results show that the highest SPI value occurred in March at the highly wet level with a value of 2.11. The lowest SPI value occurred in May at the extremely dry level with a value of -2.31. The results are then mapped using ArcGIS with the Inverse Distance Weighted (IDW) method to identify the spatial distribution of drought.

Changes in land use not only affect the hydrological component, but also have an impact on the environmental sector, which include increasing the frequency of flooding and inundation, decreasing the availability of subsurface water, and drying up community wells. Various attempts have been made in efforts to reduce flooding and maintain sources of subsurface water, for example by applying infiltration well technology in each settlement. Infiltration wells will be able to function to re-enter rainwater falling on the pavement and can reduce flooding and inundation. This research is conducted with an empirical model that is connecting the amount of runoff that occurs after the availability of recharge wells. The purpose of this research is to get the ability of infiltration wells to reduce the occurrence of flooding in an area. The data used in the analysis are rain data and soil texture data. Based on the analysis results obtained dimensions of 0.8 m, 1 m and 1.2 m infiltration wells with a depth of 2 m. The depth of ground water level is 1.94 m, the permeability value (k) of land is 0.24 x 10ˉ⁴ m / sec. From each of the infiltration well diameters, it can reduce the successive runoff namely; infiltration wells are 0.8 m in diameter from runoff of 0.479 m³ / sec and after an infiltration well is reduced to 0.057m³ / sec, infiltration wells diameter 1.2 from runoff is 0.401 m³ / sec and after an infiltration well is reduced to 0.0475 m / second, and in the diater infiltration well 2 m from runoff of 0.377 m³ / sec and after the infiltration well is reduced to 0.0571 m / sec.

AbstrakBahasa Indonesia, bahasa Melayu Kelantan, bahasa Melayu Patani, dan bahasa Sunda merupakan bahasa kerabat. Keempat bahasa tersebut termasuk rumpun bahasa Austronesia. Ketiga bahasa pertama, yaitu bahasa Indonesia, Melayu Kelantan, dan  Melayu Patani termasuk kelompok bahasa Melayu, sedangkan bahasa Sunda tidak termasuk bahasa Melayu. Bahasa Indonesia dan Sunda terdapat di Indonesia. Bahasa Melayu Kelantan terdapat di Malaysia. Bahasa Melayu Patani terdapat di Thailand. Sebagai bahasa kerabat rumpun Austronesia, keempat bahasa memiliki  kosakata  yang diwariskan dari bahasa yang lebih tua. Ciri-ciri adanya pewarisan tersebut dapat diamati pada kosakata yang memiliki persamaan atau kemiripan bentuk dan makna.  Masalah yang dibahas adalah korespondensi fonemis apa yang menunjukkan perbedaan kata kerabat yang diperoleh dari hasil membandingkan  kata kerabat pada enam glos dari empat bahasa sampel yang diteliti. Dalam tulisan ini diambil enam kata sampel bahasa Indonesia sebagai glos dari 200 glos kosakata dasar Swadesh, yaitu hapus,  hati, hidup, hijau, hitam, dan hujan. Data bersumber dari kamus dan informan. Dari hasil penelitian  terhadap kata kerabat untuk enam glos tersebut diperoleh sembilan perangkat korespondensi fonemis, yaitu (a)  /h ~ ø/ , (b) /s ~ h/, (c) /i ~ ɛ/, (d) /d ~ r/, (e) /p ~ k/, (f) /aw ~ a ~ ɔ/ , (g) /am ~ őŋ ~ ɛ/, dan (h) /-an ~ --ɛ/. Selanjutnya, setiap korespondensi fonemis tersebut menghasilkan pengelompokan bahasa yang memperlihatkan pemilik unsur bahasa yang terdapat pada korespondensi fonemis tersebut dan jika dilakukan rekonstruksi, pengelompokan bahasa tersebutmenunjukkan pencabangan dari bahasa yang lebih tua yang telah menurunkannya.Kata kunci: rumpun bahasa, kata kerabat, korespondensi fonemis, pewarisan. AbstractIndonesian, Kelantan Malay, Patani Malay, and Sundanese are kin languages. The four languages include the Austronesian language family. The first three languages, namely Indonesian, Kelantan Malay, and Patani Malay belong to the Malay language group, while Sundanese does not include Malay. Indonesian and Sundanese are found in Indonesia. Kelantan Malay is found in Malaysia. Patani Malay is found in Thailand. As the languages of relatives of Austronesian families, all four languages have vocabulary inherited from older languages. The characteristics of inheritance can be observed in vocabulary that has similarities or similarities in form and meaning. The problem discussed is the phonemic correspondence of what shows the difference in relative words obtained from the results of comparing relative words in the six glossos of the four sample languages studied. In this paper six Indonesian sample words are taken as glossos from 200 basic Swadesh vocabulary words, namely erase, heart, life, green, black, and rain. Data sourced from dictionaries and informants. From the results of research on the word relatives for the six glossos obtained nine phonemic correspondence sets, namely (a) / h ~ ø /, (b) / s ~ h /, (c) / i ~ ɛ /, (d) / d ~ r /, (e) / p ~ k /, (f) / aw ~ a ~ ɔ /, (g) / am ~ őŋ ~ ɛ /, and (h) / -an ~ --ɛ /. Furthermore, each phonemic correspondence results in a grouping of languages that shows the owner of the language elements contained in the phonemic correspondence and if a reconstruction is made, the grouping of languages shows the branching of older languages which has derived it.Keywords: language family, word relatives, phonemic correspondence, inheritance

Walking is the most accessible form for seniors to engage in daily light or moderate physical activity. Walking activity depends on both individual and environmental factors, the latter including how walkable a given setting is. Recent papers have pointed at the relevance of also considering meteorological conditions in relation to the walking behavior of older adults. This paper explores the combined effect of neighborhood walkability, temperature and rain on daily walking time among seniors residing in Barcelona. Daily walking time was extracted from 7-day GPS (Global Positioning System) devices and accelerometer data of 227 seniors residing in the Barcelona Metropolitan Region (Spain). Temperature and rain data were extracted from official governmental weather stations. Mixed-effects linear regression models were adjusted to test the combined association between weather and walkability on daily walking time. Neighborhood walkability is positively associated with walking time among seniors, while rain generally deters it. Additionally, this study demonstrates that temperature and rain modify the effect of residential walkability on senior walking activity: low temperatures are particularly associated with lower walking activity among those residing in low walkable areas, while the presence of rain presents a negative association with walking time in high walkable environments. The combined effect of walkability and weather should be considered both in design actions that aim at improving walking infrastructure and also in prevention programs aimed at encouraging daily walking among seniors.

It is standard practice in integrated urban water management to apply mathematical models of the total drainage system for calculating the frequency of occurrence of critical states in the receiving water body. The model input for such computations are long term time-series of rainfall data. However, it is inevitable that those rainfall data measurements deviate from reality. This is a result of inaccuracy of the measurement devices, errors in data transmission, local meteorological effects, etc. In this work we investigate the effect of such uncertainty in the rainfall data on the return period of the occurrence of oxygen depletion in the river due to the drainage of storm water. The errors in the rain data measurements are simulated by means of both stochastic and deterministic models. A comparison of the results obtained from the erroneous data series against the reference data reveals the small effect of random deviation in rain measurements. Only a constant and significant offset of the measured data (greater 20%) has an equally significant effect on the modeling result.
