ABSTRAK Top Soil masih memegang peranan penting untuk menunjang keberhasilan kegiatan reklamasi/revegetasi pada areal bekas tambang, khususnya pertambangan terbuka (open pit/cast). Lapisan/layer top soil yang relatif tipis/sedikit membuat kegiatan reklamasi/revegetasi menjadi tidak maksimal. Diperlukan bahan/sisa organik lain sebagai alternatif untuk menggantikan fungsi/peran top soil untuk memperbesar persentasi keberhasilan kegiatan reklamasi/revegetasi. Penelitian ini bertujuan untuk mengetahui sejauh mana peran dari bahan/sisa organik lain untuk membantu memperbaiki kualitas lahan di areal bekas tambang bauksit. Penelitian dilakukan dari mulai dari tahun 2017 sampai dengan tahun 2019, di areal reklamasi PT ANTAM Tbk UBP Bauksit, Kecamatan Tayan Hilir, Kabupaten Sanggau, Provinsi Kalimantan Barat. Metode yang digunakan adalah pembuatan dem plot ukuran 20m x 6m dengan  kolom 1 (satu) sebagai kontrol (areal tanah asli/bekas tambang),  kolom 2 (dua) untuk TKKS, Kolom 3(tiga) dengan Serasah, serta Kolom 4 (empat) dengan top soil. Keempat kolom tersebut untuk melihat sejauhmana tingkat pertumbuhan tanaman pokok (jambu hutan dan Jambu mete) dan Legume Cover Crop (LCC) dengan menggunakan perlakuan tersebut. Analisa sifat fisik kimia tanah juga dilakukan untuk mengetahui kandungan dari tiap-tiap bahan/sisa organik lain yang kemudian dibandingkan dengan top soil. Hasil penelitian menunjukkan bahwa bahan/sisa organik lain dapat memberikan konstribusi positif pada areal reklamasi/revegetasi, dengan meningkatkan percepatan pertumbuhan cover crop dan tanaman pokok. Hasil penelitian juga saat ini sudah diaplikasikan untuk kegiatan reklamasi/revegetasi PT ANTAM Tbk UBP Bauksit mulai dari tahun 2018 sampai dengan saat ini. Kata kunci : Top Soil, bahan/sisa organik lain, bekas tambang bauksit, open pit/cast, reklamasi, revegetasi, Jambu Hutan, Jambu Mete, LCC.   ABSTRACT Top Soil still plays an important role to support the success of reclamation/revegetation activities in mine out areas, especially open pitcast mining. Top soil layers that are relatively thins/lightly make reclamation/revegetation activities not optimal. Other organic materials/waste is needed as an alternative to replace the function/role of top soil to increase the percentage of successful reclamation/revegetation activities. This study aims to determine the extent of the role of other organic materialswaste to help improve the quality of land mine out areas. The study was conducted from 2017 to 2019, in the reclamation area of PT ANTAM Tbk UBP Bauksit, Tayan Hilir District, Sanggau Regency, West Kalimantan Province. The method used is making a demonstration plot of 20m x 6m size with column 1 (one) as a control (original / mine out area), column 2 (two) for TKKS Treatment, Column 3 (three) for Serasah Treatment, and Column 4 (four) with top soil. The four columns are to see the extent of growth of staple plants (local guava and Cashew) and Legume Cover Crop (LCC) using these treatments. Analysis of soil chemical physical properties was also carried out to determine the content of each other organic material /waste which was then compared with top soil. The results showed that other organic materials/waste can make a positive contribution to the reclamation / revegetation area, by increasing the acceleration of cover crop growth and staple crops. The results of the study have also been applied for the reclamation/revegetation activities of PT ANTAM Tbk UBP Bauxite starting from 2018 until now. Keywords: Top Soil, other organic materials /waste, bauxite mining, mine out,  open pit/cast, reclamation, revegetation, Local Guava, Guava, LCC, Cashew

AbstractMucuna pruriens(L.) DC is a tropical legume cover crop with promising nutritional and agronomic potentials. It is also a key source of 3,4 dihydroxy-L-phenylalanine (L-Dopa) – a precursor of dopamine used in the treatment of Parkinson's disease. However, lack of well-characterized germplasm plus poor accessibility to genomic resources has hindered its breeding programs. Furthermore, the cause and effect of various biotic and abiotic stresses impacting yield is also little studied. Systematic collection and evaluation of Indian germplasm by our group revealed presence of a diverse gene pool in India that can support a variety of breeding needs. The stability of L-Dopa trait across environments examined through Genotype and environment (G × E) interaction studies, as well as feasibility check on barcoding and phylogenetic analyses based on karyotype and conserved nuclear and chloroplast genes showed promising outcome. Germplasm screening for select biotic abiotic stresses identified resilient genotypes. Advances in use of DNA markers for diversity analysis, linkage map development, tagging of genes/quantitative trait loci for qualitative and quantitative traits, and progress in genomics are presented.

This article discusses John Locke’s positive contribution to Newman’s epistemology throughout the latter’s career. Beginning with one of Newman’s earliest published works, his Essay on Miracles, he borrowed and further developed ideas from Locke’s A Discourse on Miracles regarding the necessity of miracles to validate the Christian message and the personal nature and cumulative method of weighing evidence. Later, in Newman’s most mature epistemological work, An Essay in Aid of a Grammar of Assent, one can discern Locke’s influence on Newman’s views on the weaknesses of deductive logic, the personal nature of knowledge, and the role of connecting ideas to arrive at knowledge.

Abstract This study examined the rate of secondary traumatic stress (STS) among social work students and the contribution of background variables, personal resources (mastery and self-differentiation) and environmental resources (supervision satisfaction and peer support) to STS. The sample consisted of 259 social work students at three social work schools in Israel. The findings indicated that the mean level of STS was mild. Of the students, 36 per cent suffered STS to a mild extent, 19 per cent to a moderate extent and 18 per cent reported a ‘high to extreme extent’. A significant contribution was made by the student’s year of study, students in their second year of social work school suffered more severely from STS than did students in their first or third years. A positive contribution was made by the student’s level of exposure and a unique contribution was made by mastery and supervision satisfaction to the explained variance of STS. The findings highlight the importance of raising awareness of STS and its implications for social work students, as well as the necessity of helping students cope with this phenomenon. In addition, the study emphasises the significant role of supervisors in the training agencies and the importance of increasing students’ sense of mastery.

Legume Cover Crop

The influence of winter legume cover crops and of tillage on soil populations of fungal genera containing plant pathogenic species in the subsequent summer sorghum crop were examined in field studies. Legume cover crops significantly increased populations of Pythium spp. throughout the sorghum crop compared with a rye cover crop or no cover crop. This stimulation of the populations of Pythium spp. was not solely due to colonization of cover-crop residue, as populations were significantly greater at the time the legume cover crop was desiccated. Removal of aboveground residue generally decreased populations of Pythium spp. in soil. Incorporation of residue by tillage increased populations of Pythium spp. at some sampling dates. Legumes differed in the magnitude of stimulation, with hairy vetch stimulating Pythium spp. more than crimson clover. Cover crop treatments did not consistently influence soil populations of Fusarium spp., Rhizoctonia solani, Rhizoctonia-like binucleate fungi, or Macrophomina phaseolina. Macrophomina phaseolina populations were significantly greater under no tillage.

Thriving At Work

PurposeThe purpose of this paper is to examine the contribution of agentic work behaviour and decision-making authority (DMA) to thriving at work and, more importantly, the moderating role of DMA in the relationship between agentic behaviour and thriving.Design/methodology/approachThe study has been carried out upon a random sample of 330 employees below supervisory level from manufacturing companies located at Odisha (a state located at the eastern part of India). After verifying the significance of correlation among the study variables through Pearson’s product moment correlation, moderated regression analyses were carried out to examine the independent contribution of agentic work behaviour and DMA to thriving as well as the moderating contribution of DMA towards thriving.FindingsResults reveal that the three dimensions of agentic work behaviour, namely, task focus, exploration and heedful relation, have a direct positive contribution towards thriving at workplace. As far as the moderation is concerned, it is observed that the thriving level is higher for the employees having high DMA irrespective of the level of agentic work behaviour at each dimension.Research limitations/implicationsThe findings imply for designing interventions to enhance task focus, super-ordinate relationship and interest for learning. In addition, the organisations should provide autonomy to employees for decision making.Originality/valueThe study is first of its kind in the Indian context upon employee thriving. In this study, the authors have not only investigated the separate independent contribution of agentic behaviour and DMA, but also their interacting contribution to employee thriving.

INDEPENDENCE OF CHILDREN AGED 5-6 YEARS AT INSTITUTION OF EARLY CHILDHOOD EDUCATION IN THE DAYAK KANAYANT CULTURE. This study aims to get an overview of empirical data information on the Independence of Children 5-6 Years in Early Childhood Education Institutions in the Dayak Kanayant Culture in Nanga Kelampai Village, Tumbang Titi District, Ketapang Regency, West Kalimantan Province. This research is a qualitative research with ethnographic research. Data analysis is Spradley. The data of this study were obtained from observations, interviews and documentation. The findings of the study indicate that the independence of children aged 5-6 years in early childhood education institutions in Kanayant Dayak tribal culture is shaped by the roles and attitudes of parents and teachers and the role of the environment. The conclusion of the research shows that independent children are not formed by themselves. Parents need to equip children from an early age to be able to do their own activities without having to rely on parents.

AbstractCulture sector, which was transferred into the Ministry of Culture and Tourism since2001, was back to the Ministry of Education and Culture in October 2011. The changes oforganizational structure in ministerial level should be followed by changes of organizationalstructure in officials in provincial level. But in reality, the majority of provincial governmentsretain the culture sector together with tourism sector. This case provokes a question why thechange of organizational structure in the ministerial level is not followed by most of the officialsin provincial level. The method of this study is literature study of some articles and essays frombooks and internets, which contain history of culture sector in ministerial level, role of culturefor tourism, role of culture for education, as well as examples of official that manages culturesector in three provinces (West Kalimantan, West Sumatra, and Yogyakarta Special Region). Theresults shows that many officials merge culture sector together with tourism sector because themeaning of culture sector is considered to have a stronger synergy with tourism than education.The provincial government considers that culture sector needs to be empowered for the benefitof tourism sector. Conversely, tourism development will strengthen people’s culture in theirprovinces. Culture-based tourism development will also increase local income for the province AbstrakBidang kebudayaan yang sejak tahun 2001 bergabung dalam Kementerian Kebudayaandan Pariwisata, mulai Oktober 2011 beralih kembali ke Kementerian Pendidikan danKebudayaan. Perubahan struktur organisasi di tingkat kementerian tersebut semestinya diikutidengan perubahan struktur organisasi kedinasan di tingkat pemerintahan provinsi. Namundalam kenyataannya sebagian besar dinas di tingkat provinsi tetap mempertahankan bidangkebudayaan disatukan dengan bidang pariwisata. Hal ini menimbulkan pertanyaan, mengapaperubahan struktur organisasi di tingkat kementerian tersebut tidak diikuti oleh sebagian besardinas di tingkat provinsi? Metode yang digunakan dalam kajian ini adalah dengan melakukanstudi pustaka terhadap tulisan-tulisan dan laman-laman, yang memuat tentang sejarah bidangkebudayaan di tingkat kementerian, peran kebudayaan terhadap pariwista, peran kebudayaanterhadap pendidikan, serta contoh-contoh dinas yang menangani bidang kebudayaan di tigaprovinsi (Kalimantan Barat, Sumatera Barat, dan D.I. Yogyakarta). Hasil kajian menunjukkanbahwa hal tersebut disebabkan pemaknaan bidang kebudayaan yang dianggap lebih bersinergidengan pariwisata daripada pendidikan. Pemerintah provinsi memandang bidang kebudayaandapat diberdayakan untuk kepentingan bidang pariwisata. Sebaliknya, pengembangan pariwisataakan memperkokoh kebudayaan masyarakat di provinsi tersebut. Perkembangan pariwisatayang berbasis kebudayaan juga akan meningkatkan Pendapatan Asli Daerah (PAD) bagi provinsitersebut.
