Judul: Analisys of Flexible Working Arrangements Implementation Using Network Analysis on Twitter
Abstrak: Peningkatan penggunaan dan pengembangan teknologi yang didorong oleh pandemi COVID-19 dan konsekuensinya telah mempercepat adopsi teknologi yang baru serta meningkatkan berbagai jenis platform digital di berbagai perusahaan. Salah satunya adalah kebijakan flexible working arrangements (FWA). Penelitian ini bertujuan untuk menganalisis kebijakan terkait FWA, jaringan sosial yang terbentuk dari FWA, serta pandangan pengguna twitter mengenai FWA. Penelitian ini menggunakan metode systematic literature review dan social network analysis. Hasil penelitian menunjukkan bahwa penerapan FWA berdampak positif terhadap kinerja, produktivitas, dan keseimbangan pekerjaan dan keluarga. Dengan demikian, penerapan FWA dapat menjadi alternatif bagi perusahaan dan instansi untuk diterapkan secara permanen.

Judul: Application of Flexible Working Arrangement on Account Representative performance at Directorate General of Taxes Regional Office West Java III
Abstrak: The COVID-19 pandemic has limited many economic activities and has had a tremendous impact on the economic performance of countries in the world. The private sector and the government sector adapt to maintain job activity and maintain work productivity. The implementation of Work From Home (WFH) as part of the Flexible Working Arrangement (FWA) is a new work pattern carried out by the Ministry of Finance during the pandemic. One of the units under the Ministry of Finance that adapts work culture in the form of FWA is the Directorate General of Taxes (DGT). The Account Representative (AR) as one of the employee structures at the DGT also adjusts work patterns during the pandemic. Evaluation of AR performance during the pandemic showed a decline in performance and the many challenges that AR experienced during the pandemic. The purpose of this study was to analyze the effect of WFH on the work environment, work motivation, job satisfaction, and employee performance as well as the relationship between work environment and work motivation on job satisfaction and employee performance. This research was conducted on AR located at the Tax Service Office (KPP) in the West Java III Regional Tax Office. The number of AR that became the population of this study as of February 28, 2022 was 404 AR. The time of data collection was carried out in February 2022– Maret 2022. The types of data used are primary data and secondary data. Primary data was obtained from the results of distributing questionnaires online and secondary data obtained from journals, books, scientific writings, and articles on the internet. This research was conducted on 145 AR respondents who had filled out a questionnaire with a semantic difference scale. This research uses descriptive research method and data processing is done by SEM PLS. The results showed that WFH had a positive effect on performance either directly or through mediation of the work environment, work motivation and job satisfaction. WFH has a positive influence on the work environment, work motivation, job satisfaction and employee performance. This shows that the implementation of WFH is a work model that is quite feasible to use in the long term and has an impact on workers. The managerial implication that DGT needs to do is to formulate a measurable and systematic work model to support FWA in the long term and create evaluations that are in line with work targets. DGT needs to expand the discussion space and e-learning as a means of increasing knowledge of AR. The role of superiors as supervisors is also very important to provide support for AR kinerja performance.

Judul: Phylogeography and Species Limits in the Papuan White Snake (Micropechis ikaheka) (Reptilia: Serpentes: Elapidae)
Abstrak: Papua white snake, Micropechis ikaheka, has been distingushed into two subspecies M.i. ikaheka and M.i. fasciatus. However, due to lack of data on their morphology, distribution and ecology, both subspecies often ignored in scintific discussions and refers only byas , Micropechis ikaheka. This study was designed to document the differences between M.i. ikaheka and M.i fasciatus by using scales characteristics and reproductive organ or hemipenes. The study also examine, zoogeography, habitat, diet and cannibalism of both subspecies to better understanding the the ecology of one of the most venomous snakes in the world. This study consists of three topics with method and also different in the size samples, respectively. The first study is the histology and microtopography of the skin were studied using paraffin method and Scanning Electron Microscope (SEM). The second is the hemipenis were examined by following Myers and Cadle (2003), and Zaher and Prudente (2003). The third is the abdominal surgery was carried out to document diet type and the investigate phenomenon of cannibalism in the snake. Specimens for this study came from the collection from Museum Zoologicum Bogoriense (MZB) and Universitas Negeri Papua’s Laboratory (LZU). The research result also indicated that the markers of skin and hemipenis described the same structure and microornamentation in all M. ikaheka groups being compared. Based specimens examined morphological descriptions do not s support the further differentiation in Micropechis. In short, two markers that used in this study could not sufficiently indicate the differences in the level of species and subspecies of M. ikaheka. The study, however, were able to delineate zoogeography and skin color patterns, which fall into four groups: M. i. ikaheka; M. i. fasciatus. M. i. ssp. “intermediate”; and M. i. ssp “black”. This study also revealed that color variations did not overlap in their geographic distribution. It is therefore, it suggested that environmental factors may contribute to the skin color variations. It also assumed that habitat discontinuous and biogeography factors may also cause the loss of the connection between the original populations (vicarians) or follow colonization events (dispersal). The examined of 22 stomach contents of M. ikaheka shows this species is carnivorous, and prey on vertebrates such as amphibians, fish, reptiles, and Mammals. These snakes are opportunistic predators since they prey on all that can be captured, but mainly reptiles (61.5%), followed by mammals and fish (both 15.4%), and amphibians (7.7%). Although categorized as terrestrial animal, the diet study showed that M. ikaheka snakes often go into the water to hunt for fish (the sample from Yapen island), including eel (the sample from Aru island). Based on prey items indentified, there is evidence that M. ikaheka is cannibal. At this time, there still no record on reason for cannibalism, but it is assumed that cannibalism was due to competition between populations and means to control population.
