ABSTRACTThis study aims to determine the extent of how the Islamic entrepreneurship and environment course at pesantren based colleges are able to build the character of preneur students. The research method is a quantitative descriptive method with data analysis techniques of SPLS3 which is an alternative method of SEM to analyze how the influence of Islamic entrepreneurship and environment course on the formation of preneur students’ characters. The population in this study was 33 students of the Islamic Broadcast Communication Study Program of STIBA Ar Raayah Sukabumi, with the sample also 33 students but the one who filled out the questionnaires only 28 students which consist of 9 male students and 19 female students. The data collection technique is saturated sampling technique, which is a sampling technique using all population numbers as the respondents through a google form questionnaire. The results showed that the Islamic entrepreneurship course had no significant effect on the formation of the character of mahasantri preneur, this indicates that we need innovation in the learning process in this course. On the other hand, the environment has a great influence, this is because mahasantri always interact with asatidzah (lecturers) who run a business in their daily lives.JEL : A22, I20, M20.Keywords : islamic entrepreneurship, environment, mahasantri, college, pesantren. ABSTRAKPenelitian ini bertujuan untuk mengetahui sejauh mana mata kuliah kewirausahaan Islam dan lingkungan pada perguruan tinggi berbasis pesantren mampu membentuk karakter mahasantri preneur. Metode penelitian yang digunakan adalah metode deskriptif kuantitatif dengan teknik analisis data SPLS3 yang merupakan salah satu metoode alternatif SEM untuk menganalisis bagaimana pengaruh mata kuliah kewirausahaan Islam dan lingkungan terhadap terbentuknya karakter mahasantri preneur. Populasi dalam penelitian ini sejumlah 33 mahasantri Prodi Komunikasi Penyiaran Islam STIBA Ar Raayah Sukabumi, dengan sampel juga sebanyak 33 orang akan tetapi yang mengisi kuesioner hanya sejumlah 28 orang yang terdiri dari 9 mahasantriwan dan 19 mahasantriwati. Teknik pengambilan data berupa teknik sampling jenuh yang merupakan teknik pengambilan sampel dengan menggunakan semua jumlah populasi sebagai responden melalui kuesioner google form. Hasil penelitian menunjukkan bahwa mata kuliah kewirausahaan Islam tidak berpengaruh signifikan terhadap pembentukan karakter mahasantri prenenur, hal ini menunjukkan bahwa perlu ada inovasi dalam proses pembelajaran dalam mata kuliah ini. Sebaliknya, lingkungan memiliki pengaruh yang besar, hal ini dikarenakan para mahasantri dalam kesehariannya selalu berinteraksi dengan para asatidzah atau dosen yang pada umumnya menjalankan usaha.

AbstractMost efforts to understand snakebite burden in Nepal have been localized to relatively small areas and focused on humans through epidemiological studies. We present the outcomes of a geospatial analysis of the factors influencing snakebite risk in humans and animals, based on both a national-scale multi-cluster random survey and, environmental, climatic, and socio-economic gridded data for the Terai region of Nepal. The resulting Integrated Nested Laplace Approximation models highlight the importance of poverty as a fundamental risk-increasing factor, augmenting the snakebite odds in humans by 63.9 times. For animals, the minimum temperature of the coldest month was the most influential covariate, increasing the snakebite odds 23.4 times. Several risk hotspots were identified along the Terai, helping to visualize at multiple administrative levels the estimated population numbers exposed to different probability risk thresholds in 1 year. These analyses and findings could be replicable in other countries and for other diseases.

AbstractThe Banyuwangi Regency Government, through the Livestock Service Office, is very active in improving the community's economic level through the livestock sector. It is proven through a variety of dynamic population numbers in 2014 namely, 108,139 beef cattle. For this reason, it is necessary to get broad attention in terms of increasing the productivity of livestock. The success of increasing livestock productivity is determined by the factors of seed, feed, and management, while the largest component, which is 70%, comes from the feed factor. So far, it is rarely known that forage feed or additional feed in the form of tofu dregs or concentrate, is not completely digested in the small intestine but only about 60-70%, while the rest is excreted through feces and urine. For this reason, it is necessary to provide feed supplementation in the form of probiotics for ruminants containing several non-pathogenic microorganisms (bacteria) that can help increase feed digestibility. Probiotics can be defined as food supplements containing live microbes that have a beneficial effect on animals as their host through improving the balance of microflora in the digestive tract. Community service activities that have been carried out include the provision of probiotics for ruminants which are given directly to farmers by visiting the location of the beef cattle pen. The community service program is carried out for 5 months including counseling, training, evaluation, and cadre development. It can be concluded that there is an increase in cognitive, affective, psychomotor and substance aspects in the partner community.Keywords: beef cattle; Wongsorejo; Gombengsari; Banyuwangi AbstrakPemerintah Kabupaten Banyuwangi, melalui Dinas Peternakan sangat gencar dalam meningkatkan taraf perekonomian masyarakat melalui sektor peternakan. Terbukti melalui beragam jumlah populasi dinamis pada tahun 2014 yakni, sapi potong 108.139 ekor. Untuk itu perlu mendapat perhatian yang luas dalam hal peningkatan  produktivitas hewan ternak. Keberhasilan peningkatan  produktivitas peternakan ditentukan oleh faktor bibit, pakan dan pengelolaan, sedangkan komponen terbesar yaitu sebesar 70 % berasal dari faktor pakan. Selama ini jarang diketahui  bahwa pakan hijauan maupun pakan tambahan berupa ampas tahu atau konsentrat, tidak seluruhnya dicerna dalam usus halus melainkan hanya sekitar 60-70 %,sedangkan yang sisanya dibuang lewat feses dan urine. Untuk itu  perlu dilakukan pemberian suplementasi pakan berupa pro biotik untuk Ruminan yang mengandung beberapa mikroorganisme (bakteri) non patogen yang mampu membantu peningkatan kecernaan pakan. Probiotik dapat didefinisikan sebagai suplemen makanan yang mengandung mikrobial hidup menimbulkan efek menguntungkan hewan sebagai induk semangnya melalui peningkatan  keseimbangan mikroflora di dalam saluran pencernaan. Kegiatan pengabdian kepada masyarakat yang telah dilakukan meliputi pemberian probiotik untuk ruminan yang diberikan secara langsung kepada peternak dengan mendatangi lokasi kandang sapi pedaging. Program pengabdian masyarakat dilakukan selama 5 bulan meliputi penyuluhan, pelatihan, evaluasi, dan pembinaan kader. Dapat disimpulkan terdapat peningkatan aspek kognitif, afektif, psikomotor dan substansi pada masyarakat mitra.Kata kunci: sapi potong; Wongsorejo; Gombengsari; Banyuwangi

The dolphins Inia geoffrensis—boto and Sotalia fluviatilis—tucuxi are threatened cetaceans inhabiting river ecosystems in South America; population numbers are still lacking for many areas. This paper provides density and abundance estimations of boto and tucuxi in 15 rivers sampled during the past nine years as part of a multinational research alliance. Visual boat-survey data collection protocols and analyses have been developed since 2012 (based on Distance Sampling methods) and recently reviewed (2019) to improve robustness and comparability. Differences across the sampled rivers and the analyzed river basins (Amazon and Orinoco) pointed to a density/population size gradient with lower densities and abundances observed in the Orinoco basin (0.9–1.5 ind./km²), passing through the eastern Amazon basin (2–5 ind./km²), and the largest numbers found at the central Brazilian Amazon (lower Purus River—2012 (14.5 boto/km², N = 7672; 17.1 tucuxi/km², N = 9238)). However, in other parts of the central Amazon, the density of dolphins was smaller than expected for high productive whitewater rivers (1–1.7 ind./km² in the Japurá and Solimões rivers). We attributed these differences to specific features of the basin (e.g., hydro-geomorphology) as well as to the cumulative effects of anthropogenic activities.

The Covid-19 pandemic has caused within a period of one year and eight months over 200,000,000 infections and more than 4,000,000 deaths. It is of paramount importance to design powerful and robust tools in order to be able to predict the evolution of the disease. In this paper, the computational framework COVID-LIBERTY is introduced, in order to assist the study of the pandemic in Europe. In Part 1, important parameters that should be taken into consideration and their parametrizations were given, as well as the details and mathematics of the computational engine of COVID-LIBERTY, a feed-forward, back-propagation Artificial Neural Network. In Part 2, the CPRT index is introduced, the framework setup around the Artificial Neural Network is presented and the algorithm of ensemble modeling is discussed, which improves the accuracy of the predictions. In the simulations, 4 European countries with similar population numbers were considered. The capabilities of the COVID-LIBERTY framework for accurate predictions for periods up to 19 days will be demonstrated.

Abstract A recent study published in The Lancet predicts a remarkable drop in population numbers following a peak that will be reached by 2064. A unique feature of the upcoming population drop is that it will be almost exclusively caused by decreased reproduction, rather than factors that increase rates of mortality. The reasons for decreased reproduction are also unique, as, unlike previous centuries, limited reproduction today is hardly due to a shortage in resources. In other words, the predicted population drop is almost exclusively due to changes in reproductive behavior and reproductive physiology. Today, global changes in reproductive behavior are mostly explained by social sciences in a framework of demographic transition hypotheses, while changes in reproductive physiology are usually attributed to effects of endocrine-disrupting pollutants. This review outlines a complementary/alternative hypothesis, which connects reproductive trends with population densities. Numerous wildlife and experimental studies of a broad range of animal species have demonstrated that reproductive behavior and reproductive physiology are negatively controlled via endocrine and neural signaling in response to increasing population densities. The causal chain of this control system, although not fully understood, includes suppression of every level of hypothalamic-pituitary-gonadal cascade by hypothalamic-pituitary-adrenal axis, activated in response to increasing stress of social interactions. This paper discusses evidence in support of a hypothesis that current trends in reproductive physiology and behavior may be partly explained by increasing population densities. Better understanding of the causal chain involved in reproduction suppression by population density–related factors may help in developing interventions to treat infertility and other reproductive conditions.

The enigmatic ghost orchid, Dendrophylax lindenii (Lindley) Bentham ex Rolfe, is a showy leafless epiphyte restricted to low-lying forests in south Florida and western Cuba. Because of its appeal and reputation for being difficult to cultivate, D. lindenii remains vulnerable to poaching and environmental changes. About 2000 individuals are assumed to remain in Florida, most confined within water-filled cypress domes in the Fakahatchee Strand, but virtually no information exists on current population numbers throughout the region. This paper provides a preliminary summary of the ghost orchid’s projected status based on six continuous years of data collected within the Florida Panther National Wildlife Refuge (FPNWR) from 2015–2020. The orchids were clustered in seven different populations, each separated by ca. 5 km. Quantitative data were collected spanning three age classes (seedlings, juveniles, mature plants) for each population, and survival, flowering, and fruiting were noted. To estimate the temporal variability in the demographic rates, size-structured integral projection models (IPMs) were constructed for each annual transition (e.g., 2015–2016, 2016–2017). Results for all seven populations pooled suggest that D. lindenii numbers will decline by 20% during the next decade in the absence of external adverse factors. Seedling recruitment is not expected to keep pace with the projected decline. Only one population, which was also from the wettest location, continuously harbored spontaneous seedlings, suggesting that most populations within the FPNWR lack conditions suitable for reproduction.

Density dependence in reproduction plays an important role in stabilising population dynamics via immediate negative feedback from population density to reproductive output. Although previous studies have shown that density dependence is associated with strong spacing behaviour and social interaction between individuals, the proximal mechanism for generating density-dependent reproduction remains unclear. In this study, we investigated the effects of density-induced stress on reproduction in root voles. Founder population enclosures were established by introducing six (low density) and 30 (high density) adults per sex into per enclosure (four enclosures per density in total) during the breeding season from April to July 2012 and from May to August 2015. Faecal corticosterone metabolite (FCM) levels, reproductive traits (recruitment and the proportion of reproductive condition), and founder population numbers were measured following repeated live-trapping in both years. The number of founders was negatively associated with recruitment rates and the proportion of reproductive conditions, displaying a density-dependent reproduction. FCM level was positively associated with the number of founders. The number of founder females indirectly affected the proportion of reproductive females in 2012 and recruitment in 2015 through their FCM levels; the effect of the number of male founders on the proportion of reproductive condition was mediated by their FCM level in 2012, but the effect was not found in 2015. Our results showed that density-induced stress affected density-dependent reproduction and that density-induced stress is one ecological factor generating density-dependent reproduction.

Human populations have grown to such an extent that our species has become a dominant force on the planet, prompting geologists to begin applying the term Anthropocene to recognize the present moment. Many approaches seek to explain the past and future of human population growth, in the form of narratives and models. Some of the most influential models have parameters that cannot be precisely known but are estimated by expert opinion. Here we apply a unified model of ecology to provide a macroscale summary of the net effects of many microscale processes, using a minimal set of parameters that can be known. Our models match estimates of historic and prehistoric global human population numbers and provide predictions that correspond to some of the more complicated current models. In addition to fitting the data well they reveal that, amidst enormous complexity in our human and prehuman past, three key ecological discontinuities have occurred in turn: 1) becoming dominant competitors of large predators rather than their prey, 2) becoming mutualists with food species rather than acting as predators upon them, and 3) changing from a regime of uncontrolled population growth to one of controlled fertility instead. All three processes have been interlinked with cultural evolution and all three ushered in developments of the Anthropocene. Understanding the trajectories that have delivered us to this stage can help guide prudent paths into the future.
