New Jobs

The development of the digital economy leads to the loss of several jobs and the emergence of new jobs. It also allows labor shifting between the new jobs and the old jobs. This phenomenon could raise the potential for unabsorbed labor which will cause unemployment problems. The COVID-19 pandemic, which requires large-scale social restrictions (PSBB), has certainly affected the transportation sector. This study aims to examine the influence of the digital economy, investment, the COVID-19 pandemic, and the Job Creation Law on the labor market structure of the transportation sector in Indonesia. The research method used is quantitative. The data used are the time series from January 2018 to November 2020. The results of this study indicate that the digital economy has no effect on the structure of the labor market in the transportation sector in Indonesia. Meanwhile, investment, the COVID-19 pandemic, and the Job Creation Law, respectively, have a significant effect on the structure of the labor market in the transportation sector in Indonesia. The impact of investment and the COVID-19 pandemic on the labor market structure of the transportation sector in Indonesia is negative. Meanwhile, the effect of the Job Creation Law on the labor market structure of the transportation sector in Indonesia is positive. Simultaneously, the digital economy, investment, the COVID-19 pandemic, and the Job Creation Law affect the labor market structure of the transportation sector in Indonesia.

The Impact

Chapter 2 digs more deeply into the outlook for job destruction and job creation, and adds some theory and data to Chapter 1’s anecdotes about how machines can replace human workers. It reports an emerging consensus among leading scholars that automation is already contributing to the polarization, or hollowing out, of the labor market by destroying more middle-skill jobs than it is creating. And it reports on the more concerning prediction—still a minority view though more than plausible—that machines are destined to produce overall net job losses as they continually whittle away at humans’ comparative advantages. The chapter arrives at a working premise for the rest of the book that straddles those two forecasts: We are facing a future of less work—at least less work for those with ordinary human skills and without advanced education, and perhaps less work overall. While that straddle might seem untenable, either forecast is similarly bleak for most workers—if we do not respond constructively; and when it comes to the shape of a constructive response, both forecasts point largely in the same direction.

Advances in synthetic aperture radar (SAR) interferometry have enabled the seamless monitoring of the Earth’s crust deformation. The dense archive of the Sentinel-1 Copernicus mission provides unprecedented spatial and temporal coverage; however, time-series analysis of such big data volumes requires high computational efficiency. We present a parallelized-PSI (P-PSI), a novel, parallelized, and end-to-end processing chain for the fully automated assessment of line-of-sight ground velocities through persistent scatterer interferometry (PSI), tailored to scale to the vast multitemporal archive of Sentinel-1 data. P-PSI is designed to transparently access different and complementary Sentinel-1 repositories, and download the appropriate datasets for PSI. To make it efficient for large-scale applications, we re-engineered and parallelized interferogram creation and multitemporal interferometric processing, and introduced distributed implementations to best use computing cores and provide resourceful storage management. We propose a new algorithm to further enhance the processing efficiency, which establishes a non-uniform patch grid considering land use, based on the expected number of persistent scatterers. P-PSI achieves an overall speed-up by a factor of five for a full Sentinel-1 frame for processing in a 20-core server. The processing chain is tested on a large-scale project to calculate and monitor deformation patterns over the entire extent of the Greek territory—our own Interferometric SAR (InSAR) Greece project. Time-series InSAR analysis was performed on volumes of about 12 TB input data corresponding to more than 760 Single Look Complex Sentinel-1A and B images mostly covering mainland Greece in the period of 2015–2019. InSAR Greece provides detailed ground motion information on more than 12 million distinct locations, providing completely new insights into the impact of geophysical and anthropogenic activities at this geographic scale. This new information is critical to enhancing our understanding of the underlying mechanisms, providing valuable input into risk assessment models. We showcase this through the identification of various characteristic geohazard locations in Greece and discuss their criticality. The selected geohazard locations, among a thousand, cover a wide range of catastrophic events including landslides, land subsidence, and structural failures of various scales, ranging from a few hundredths of square meters up to the basin scale. The study enriches the large catalog of geophysical related phenomena maintained by the GeObservatory portal of the Center of Earth Observation Research and Satellite Remote Sensing BEYOND of the National Observatory of Athens for the opening of new knowledge to the wider scientific community.

There are a large number of lakes with beaded distribution in the semi-arid areas of the Inner Mongolian Plateau, and some of them have degraded or even disappeared during the past three decades. We studied the reasons of the disappearance of these lakes by determining the way of replenishment of these lakes and the impact of the natural-social environment of the basin, with the aim of saving these gradually disappearing lakes. Based on remote sensing image and hydrological analysis, this paper studied the recharge of Daihai Lake and Huangqihai Lake. The deep learning method was used to establish the time-series of lake evolution. The same method was combined with the innovative woodland and farmland extraction method to set up the time-series of ground classification composition in the basins. Using relevant survey data, combined with soil water infiltration test, water chemical, and isotopic signature analysis of various water bodies, we found that the Daihai Lake area is the largest in dry season and the smallest in rainy season and the other lake is not satisfied with this phenomenon. In addition, we calculated the specific recharge and consumption of the study basin. These experiments indicated that the exogenous groundwater is recharged directly through the faults at the bottom of Daihai Lake, while the exogenous groundwater is recharged in Huangqihai Lake through rivers indirectly. Large-scale exploitation of groundwater for agricultural irrigation and industrial production is the main cause of lake degradation. Reducing the extraction of groundwater for agricultural irrigation is an important measure to restore lake ecology.

Abstract. An important aspect to assess the impact of climate change on water availability is to have monthly time series representative of the current situation. In this context, a simple methodology is presented for application in large-scale studies in regions where a properly calibrated hydrologic model is not available, using the output variables simulated by regional climate models (RCMs) of the European project PRUDENCE under current climate conditions (period 1961–1990). The methodology compares different interpolation methods and alternatives to generate annual times series that minimize the bias with respect to observed values. The objective is to identify the best alternative to obtain bias-corrected, monthly runoff time series from the output of RCM simulations. This study uses information from 338 basins in Spain that cover the entire mainland territory and whose observed values of naturalised runoff have been estimated by the distributed hydrological model SIMPA. Four interpolation methods for downscaling runoff to the basin scale from 10 RCMs are compared with emphasis on the ability of each method to reproduce the observed behavior of this variable. The alternatives consider the use of the direct runoff of the RCMs and the mean annual runoff calculated using five functional forms of the aridity index, defined as the ratio between potential evaporation and precipitation. In addition, the comparison with respect to the global runoff reference of the UNH/GRDC dataset is evaluated, as a contrast of the "best estimator" of current runoff on a large scale. Results show that the bias is minimised using the direct original interpolation method and the best alternative for bias correction of the monthly direct runoff time series of RCMs is the UNH/GRDC dataset, although the formula proposed by Schreiber also gives good results.

The Impact

Earlier investigations into the epochal behavior of fluctuations in All India Summer Monsoon Rainfall (AISMR) have indicated the existence of a Low Frequency Mode (LFM) in the 60-70 years range. One of the probable sources of this variability may be due to changes in solar irradiance. To investigate this, time series of 128-year solar irradiance data from 1871-1998 has been examined. The Wavelet Transform (WT) method is applied to extract the LFM from these time series, which show a very good correspondence. A case study has been carried out to test the sensitivity of AISMR to solar irradiance. The General Circulation Model (GCM) of the Center of Ocean-Land-Atmosphere (COLA) has been integrated in the control run (using the climatological value of solar constant i.e., 1365 Wm-2) and in the enhanced solar constant condition (enhanced by 10 Wm-2) for summer monsoon season of 1986. The study shows that the large scale atmospheric circulation over the Indian region, in the enhanced solar constant scenario is favorable to good monsoon activity. A conceptual model for the impact of solar irradiance on the AISMR at LFM is also suggested.

AbstrakRencong merupakan produk budaya lokal Aceh yang diwariskan secara turun-temurun oleh nenek monyangnya suku Aceh. Rencong sebagai senjata tradisional sekaligus simbol identitas diri masyarakat Aceh memiliki sejarah panjang dan bentuk yang menarik. Sampai saat ini rencong Aceh tetap diminati oleh masyarakat Aceh maupun pendatang yang berkunjung ke daerah Aceh. Seiring dengan berlakunya PSBB di Aceh, juga berdampak terhadap pengrajin rencong, Kondisi ini juga menuntut masyarakat harus mencari pekerjaan lain untuk dapat memenuhi kebutuhan hidup sehari-hari, dampak virus covid-19 dirasakan langsung oleh pengrajin rencong yang ada di tiga desa Baet yaitu, Baet Masjid, Baet Lampuot dan Baet Meusago di kecamatan Sukamakmur Kabupaten Aceh Besar. Beberapa pengrajin yang bertahan, dikarenakan tidak adanya pekerjaan lain seperti yang dilakukan oleh bapak Yudi Hidayat, Ibrahin dan Zuhri. Pemerintah Aceh bahkan telah menetapkan kampung-kampung ini sebagai kampung rencong yang menjadi destinasi wisata baru di Aceh. Sebelum Covid- 19 hampir semua penduduknya berpropesi sebagai pengrajin rencong. Membuat rencong dilakukan secara turun-temurun dimana pembuatan kerajinan ini dilakukan oleh laki-laki dan perempuan. Keunikan rencong dapat dilihat dari bentuknya yang menyerupai kalimat Bismillah ditulis dalam bahasa Arab. Hal ini menunjukkan adanya hubungan erat antara rencong dengan Islam. Perubahan zaman tentunya turut mengubah kebudayaan, dalam hal ini turut merubah bentuk rencong dan fungsi rencong itu sendiri, dimana dahulunya bentuk rencong hanya berukuran 35 cm dan dalam perkembanganya bentuk rencong saat ini sudah mulai ber pariasi mulai dari ukuran 15 cm sampai dengan 2 M, selain itu rencong pada saat ini produksi lebih memanfaatkan pamor rencong sebagai salah satu senjata khas Aceh yang ada di Indonesia sehingga fungsinya beralih dari fungsi praktis menjadi fungsi estetis sehingga tujuan produksinya turut mempengaruhinya, dimana rencong saat ini sudah digunakan sebagai aksesoris dalam pakaian adat Aceh dan aksesoris dalam pagelaran pertunjukan. Metode penelitian “Perkembangan Bentuk Kerajinan Rencong di Desa Baet Kecamatan Suka Makmur Kabupaten Aceh Besar” ini dilakukan dengan menggunakan penelitian kualitatif. Metode ini dapat menjawab semua rumusan masalah dalam penelitian ini. metode kualitatif juga dapat menggali informasi secara mendalam.  Kata Kunci: rencong, kerajinan, fungsi estetis.AbstractRencong is a product of local Aceh culture that has been passed down from generation to generation by his Acehnese mony grandmother. Rencong as a traditional weapon as well as a symbol of Acehnese identity has a long history and an interesting form. Until now, Aceh rencong is still in demand by Acehnese people and migrants visiting the area. Along with the enactment of the Large-Scale Social Restrictions in Aceh it also has an impact on rencong craftsmen, this condition also requires people to find other jobs to be able to meet their daily needs, the impact of the covid-19 virus is felt directly by rencong craftsmen in three Baet villages, namely, Baet Masjid, Baet Lampuot and Baet Meusago in Sukamakmur sub-district, Aceh Besar district. Some of the craftsmen who survived, were due to the absence of other jobs such as those done by Yudi Hidayat, Ibrahin and Zuhri. In this case, the Aceh government has even designated these villages as Rencong villages which have become new tourist destinations in Aceh. Almost all residents work as rencong craftsmen. Making rencong has been done from generation to generation. The making of this craft is done by both men and women. The uniqueness of rencong can be seen from its shape which resembles the sentence Bismillah written in Arabic. This shows the close relationship between rencong and Islam. Changes in time have certainly changed the culture, in this case also changing the shape of the rencong and the function of the rencong itself, where previously the shape of the rencong was only 35 cm in size and in its development the shape of the rencong now varies from 15 cm to 2 M in size, besides The current rencong production utilizes the prestige of rencong as one of Aceh's typical weapons in Indonesia so that its function is shifted from a practical function to an aesthetic function so that its production objectives also influence, where rencong is currently used as an accessory in Acehnese traditional clothing and accessories in performances the research method "Development of Rencong Craft Forms in Baet Village, Suka Makmur District, Aceh Besar District. "This is done using qualitative research. This method can answer all problem formulations in this study. Qualitative methods can also digging information.  Keywords: rencong, craft, aesthetic function..
