Hukum dan masyarakat memiliki fungsi yang saling berkaitan. Fungsi hukum pada masyarakat adalah untuk mencegah konflik kepentingaan. Jika terjadi, maka hukum menjadi penyedia cara untuk menyelesaikannya berdasarkan kebijakan yang didasarkan pada norma yang berlaku. dengan keterkaitan hukum dan masyarakat, maka perbuatan masyarakat untuk main hakim sendiri akan terhindar. Semua persoalan dan konflik kepentingan yang ada di masyarakat harus diselesaikan melalui jalur hukum. Dari sinilah fungsi hukum dan masyarakat berkaitan. hukum mengandung unsur aturan perilaku manusia, sedangkan regulasi dipegang oleh badan resmi yang memiliki wewenang. Sementara untuk karakteristik yang melekat dalam hukum, menurutnya karena adanya perintah dan larangan. Larangan dan perintah harus dipatuhi dan dipatuhi oleh orang-orang dan adanya sanksi hukum yang ketat. Intinya hukum dimaksudkan untuk mengatur hubungan perilaku dan hubungan yang ada di masyarakat. Baik dilakukan oleh satu orang dengan orang lain, individu dengan negara dan mengatur hubungan institusi yang ada di negara tersebut. dengan hukum, kekuasaan dilaksanakan sesuai dengan fungsi dan tujuan hukum itu sendiri.Kata Kunci: Hukum, Masyarakat, Sosiologi Hukum

Published: July 2021

Penyelesaian kasus kekerasan rumah tangga idealnya mencari alternatif yang memulihkan keadaan seperti semula tetapi realitas sosial menunjukkan tingkat keberhasilan mediasi penal masih cukup rendah sehingga harapan atas keadilan restorative justice untuk menjaga keharmonisan rumah tangga belum tercapai. Penelitian ini bertujuan untuk mendeskripsikan penyelesaian perkara KDRT melalui mediasi penal dihubungkan dengan keadilan restoratif dan menentukan akibat hukum atas kesepakatan damai yang dihasilkan mediasi penal terhadap penyidikan tindak pidana KDRT di Kota Pekanbaru. Penelitian ini menggunakan pendekatan hukum normatif. Spesifikasi penelitian deskriptif analisis, jenis data sekunder, teknik pengumpulan data studi dokumentasi dengan menggunakan teknik analisis kualitatif. Hasil penelitian menunjukan (1) Tindak pidana KDRT di Kota Pekanbaru secara faktual cenderung diselesaikan secara formal (litigasi) diikuti dengan permohonan perceraian disebabkan upaya mediasi penal belum menunjukkan usaha dan hasil yang memadai karena secara empiris ditemukan beberapa persoalan mendasar, yaitu (a) masalah operasional (lemahnya komunikasi penegak hukum dengan para pihak, keterbatasan waktu, tindak lanjut hasil medasi) (b) kualitas (kompetensi) penegak hukum (c) masalah kepatuhan pelaku untuk menjalankan kesepakatan mediasi terbukti dengan adanya pengulangan tindak kekerasan kepada korban (2) Kesepakatan perdamaian antara pelaku dengan korban dan keluarganya sebagai hasil proses mediasi penal menimbulkan akibat hukum terhadap proses penegakan hukum berupa penghentian proses penyidikan tindak pidana kekerasan dalam rumah tangga yang sedang berjalan di Kota Pekanbaru karena akta perdamaian yang disepakati para pihak merupakan produk hukum yang memiliki kekuatan hukum mengikat untuk dihormati dan dijalankan para pihak supaya memberikan kepastian hukum bagi status perkara di masa mendatang. Penghentian penyidikan merupakan kebijakan diskresi penegak hukum di Kota Pekanbaru dengan syarat apabila pelaku mengingkari kesepakatan damai dengan mengulangi tindak pidana kekerasan maka langsung diproses secara formal (pengadilan).  Kata Kunci : Kekerasan Dalam Rumah Tangga, Mediasi Penal, Keadilan Restoratif

Palm liquid sewage is organic waste that contains complex compounds such as water, oil, and organic solids. The organic content of palm liquid sewages is an indication of the abundance of microorganisms. This study aims to obtain anoxygenic photosynthetic bacteria (BFA) that produce carotenoid pigments from palm liquid sewages. Therefore, We isolated and screened of BFA from three palm liquid sewage disposal sites in Jambi Province. This research was conducted by an experimental method using a modified mineral medium. BFA isolates that growth and produced carotenoid pigments are visible because of the distribution of reddish-yellow pigments on the culture media. Screening results obtained 11 isolates of BFA sequentially Bg1K201, Bg1K202, Bg2k201, Bg3k201, Mr1k201, Mr1k202, Sl1k201, Sl1k202, Sl2k201, Sl2k202 and Sl3k202.

Optimal Model Predictive Frequency Control Management of Grid Integration PV/Wind/FC/Storage Battery Based Smart Grid Using Multi Objective Particle Swarm Optimization MOPSO
Authors: Elgammal Adel , Ramlal Tagore
Published: July 2021

This article forecasts the performance of smart-grid electrical transmission systems and integrated battery/FC/Wind/PV storage system renewable power sources in the context of unpredictable solar and wind power supplies. The research provided a hybrid renewable energy sources smart grid power system electrical frequency control solution using adaptive control techniques and model predictive control (MPC) based on the Multi-Objective Practical Swarm Optimization Algorithm MOPSO. To solve the problems of parameter tuning in Load Frequency Control, the suggested adaptive control approach is utilized to accomplish on-line adjustment of the Load Frequency Control parameters. During the electrical grid's integration, the system under investigation is a hybrid Wind/PV/FC/Battery smart grid with variable demand load. To achieve optimal outcomes, all of the controller settings for various units in power grids are determined by means of a customized objective function and a particle swarm optimization method rather than a regular objective function with fluctuating restrictions. To suppress the consumption and generation balance, MPCs were designed for each of the Storage Battery, Wind Turbine Generation, and the model Photovoltaic Generation. In addition, demand response (real-time pricing) was used in this scheme to reduce the load frequency by adjusting the controlled loads. The suggested control strategy is evaluated in the Simulink /MATLAB environment in order to analyse the suggested approach's working in the power system, as well as its effectiveness, reliability, robustness, and stability. The simulation findings show that the proposed control method generally converges to an optimal operating point that minimises total user disutility, restores normal frequency and planned tie-line power flows, and maintains transmission line thermal restrictions. The simulation results further indicate that the convergence holds even when the control algorithm uses inaccurate system parameters. Finally, numerical simulations are used to illustrate the proposed algorithm's robustness, optimality, and effectiveness. In compared to previous methodologies, the system frequency recovers effectively and efficiently in the event of a power demand disturbance, as demonstrated. A sensitivity test is also performed to assess the suggested technique's effectiveness.
Examining LDA2Vec and Tweet Pooling for Topic Modeling on Twitter Data
Authors: Culmer Kristofferson , Uhlmann Jeffrey
Published: July 2021

The short lengths of tweets present a challenge for topic modeling to extend beyond what is provided explicitly from hashtag information. This is particularly true for LDAbased methods because the amount of information available from pertweet statistical analysis is severely limited. In this paper we present LDA2Vec paired with temporal tweet pooling (LDA2VecTTP) and assess its performance on this problem relative to traditional LDA and to Biterm Topic Model (Biterm), which was developed specifically for topic modeling on short text documents. We paired each of the three topic modeling algorithms with three tweet pooling schemes: no pooling, authorbased pooling, and temporal pooling. We then conducted topic modeling on two Twitter datasets using each of the algorithms and the tweet pooling schemes. Our results on the largest dataset suggest that LDA2VecTTP can produce higher coherence scores and more logically coherent and interpretable topics.

It is a well-known concept that bone remodeling occurs during orthodontic tooth movement. The orthodonticliterature is vastly full of information about the changes occurring on the periodontal ligament level.However, changes occurring in the alveolar bone are being elucidated. What we know about bone resorptionhas changed a lot in the last few decades. The osteoclast is the only cell to nibble and breakdown the bone,and also aids in formation and resorption of bone tissue. In this review, we briefly describe the phases andtheories of tooth movement and also the changes involved during orthodontic tooth movement.

Objective: This study aimed to examine the psychological work environments and associated factors among clinical nurses in a provincial tertiary hospital in the North of Vietnam in 2020. Methods: A cross-sectional survey was conducted among all nurses of 22 clinical wards who directly provided care to patients. 261/318 eligible nurses returned the self-reported survey questionnaires that consisted of the Vietnamese version of the Job Content Questionnaire 22 items and originally developed questions on personal characteristics and work conditions. Descriptive analysis, t-test, ANOVA, and multivariate linear regressions were applied to describe the current job demand, job control, and related factors at the significant level p less than 0.05. Results: The response rate of the current study was 82.1%. Nurses reported moderate job demand (29.39±3.64) and job control (66.86±5.79). Increased job control was significantly associated with more frequency of receiving support from superiors (p<0.001), a self-perceived opportunity of promotion (p = 0.011), and more night shifts per week (p=0.004). Less support from co-workers and more night shifts were associated with a higher job demand score among study participants (p = 0.041 and 0.002, respectively). Conclusions: Several nurses in the provincial hospital work in unfavorable work environments with high job demand and low job control, which could adversely affect nurses’ well-being. It is essential to promote social support at work to improve the psychological working conditions and performance of study participants.

Office buildings built before the entry into force of the first thermal regulation in 1991 constitute a relevant group for analysing the energy performance of the Portuguese building sector. A dynamic energy simulation was used to assess the energy performance of an existing office building located in the town of Bragança, Portugal. Four energy efficiency measures were selected and a financial evaluation through the internal rate of return (IRR) method was undertaken to choose the best retrofit option for improving the building’s energy performance. An investment package consisting of the roof insulation and a new equipment for the domestic hot water system presented an IRR higher than the discount rate used in the analysis, and, thus, a positive financial return. The results of the study also suggest that the EU’s comparative methodology framework is not particularly suitable for assessing building retrofit investment at the private investor’s perspective and further refinement in the cost-effective approach to renovations is needed to help stimulate building’s energy renovation market. Suggestions for further studies conducted for office buildings in the different climate zones in Portugal are also proposed.
How Close are Compact Multiplanet Systems to the Stability Limit?

Transit surveys have revealed a significant population of compact multiplanet systems, containing several sub-Neptune–mass planets on close-in, tightly-packed orbits. These systems are thought to have formed through a final phase of giant impacts, which would tend to leave systems close to the edge of stability. Here, we assess this hypothesis, comparing observed eccentricities in systems exhibiting transit-timing variations versus the maximum eccentricities compatible with long-term stability. We use the machine-learning classifier SPOCK (Tamayo et al.) to rapidly classify the stability of numerous initial configurations and hence determine these stability limits. While previous studies have argued that multiplanet systems are often maximally packed, in the sense that they could not host any additional planets, we find that the existing planets in these systems have measured eccentricities below the limits allowed by stability by a factor of 2–10. We compare these results against predictions from the giant-impact theory of planet formation, derived from both N-body integrations and theoretical expectations that, in the absence of dissipation, the orbits of such planets should be distributed uniformly throughout the phase space volume allowed by stability. We find that the observed systems have systematically lower eccentricities than this scenario predicts, with a median eccentricity about four times lower than predicted. This suggests that, if these systems formed through giant impacts, then some dissipation must occur to damp their eccentricities. This may occur through interactions with the natal gas disk or a leftover population of planetesimals, or over longer timescales through the coupling of tidal and secular processes.

We report the discovery of two planetary systems around comoving stars: TOI-2076  (TIC 27491137) and TOI-1807 (TIC 180695581). TOI-2076  is a nearby (41.9 pc) multiplanetary system orbiting a young (204 ± 50 Myr), bright (K = 7.115 in TIC v8.1) start. TOI-1807 hosts a single transiting planet and is similarly nearby (42.58 pc), similarly young (180 ± 40 Myr ), and bright. Both targets exhibit significant, periodic variability due to starspots, characteristic of their young ages. Using photometric data collected by TESS  we identify three transiting planets around TOI-2076  with radii of R

 = 10.356 days. For both TOI-2076c and d, TESS  observed only two transits, separated by a 2 yr interval in which no data were collected, preventing a unique period determination. A range of long periods (<17 days) are consistent with the data. We identify a short-period planet around TOI-1807 with a radius of R

b
 = 1.8 ± 0.04 R
⊕ and a period of P

b
 = 0.549 days. Their close proximity, and bright, cool host stars, and young ages make these planets excellent candidates for follow up. TOI-1807b  is one of the best-known small (R < 2

) planets for characterization via eclipse spectroscopy and phase curves with JWST. TOI-1807b  is the youngest ultra-short-period planet discovered to date, providing valuable constraints on formation timescales of short-period planets. Given the rarity of young planets, particularly in multiple-planet systems, these planets present an unprecedented opportunity to study and compare exoplanet formation, and young planet atmospheres, at a crucial transition age for formation theory.
A Weakening Compton Hump and Soft X-Ray Excess Detected in the Seyfert 1 Galaxy MCG –02–58–22
Authors: Laha Sibasish , Ghosh Ritesh
Published: July 2021

We have carried out an extensive X-ray spectral study of the bare Seyfert 1 galaxy MCG –02–58–22 to ascertain the nature of the X-ray reprocessing media using observations from Suzaku (2009) and simultaneous observations from XMM-Newton and NuSTAR (2016). The most significant results of our investigation are as follows. (1) The primary X-ray emission from the corona is constant in these observations, in terms of both the power-law slope (Γ = 1.80) and luminosity (L
2−10 keV = 2.55 × 1044 erg s−1). (2) The soft excess flux decreased by a factor of 2 in 2016, the Compton hump weakened/vanished in 2016, and the narrow FeKα emission line became marginally broad (σ = 0.35 ± 0.08 keV) and its flux doubled in 2016. (3) From physical model fits, we find that the normalization of the narrow component of the FeKα line does not change in the two epochs, although the Compton hump vanishes in the same time span. Since the primary X-ray continuum does not change, we presume that any changes in the reprocessed emission must arise due to changes in the reprocessing media. Our primary conclusions are as follows. (a) The vanishing of the Compton hump in 2016 can probably be explained by a dynamic clumpy torus that is infalling/outflowing or a polar dusty wind. (b) The torus in this active galactic nucleus possibly has two structures: an equatorial toroidal disk (producing the narrow FeKα emission) and a polar component (producing the variable Compton hump). (c) The reduction of the soft excess flux by half and increase in the FeKα flux by a factor of 2 in the same period cannot be adequately explained by an ionized disk reflection model alone.
Alteration of the feeding behavior of an omnivorous fish, Scardinius acarnanicus (Actinopterygii: Cypriniformes: Cyprinidae), in the presence of fishing lights

Published: July 2021

Fishing with light is an old and common practice yielding a substantial catch volume globally. Despite the popularity of the method and the efforts to improve it, there is a lack of field studies on the effects of light on the feeding preferences of the attracted fishes. A previous report suggested that purse seine fishing lights can differentiate the feeding preferences of the approaching fishes, such as Atherina boyeri Risso, 1810 in Lake Trichonis (Greece). The presently reported study aims to verify these findings by investigating the diet of the endemic Scardinius acarnanicus Economidis, 1991. The feeding behavior of S. acarnanicus was studied from 2016 to 2019 through gut content analysis, in specimens from Lake Trichonis that came from purse seining with light and specimens caught without light. The same investigation was carried out comparatively in specimens taken by gillnets from two nearby lakes (lakes Ozeros and Amvrakia), where S. acarnanicus is present, but no fishing with light is exercised. The stomach content analysis conducted on 699 S. acarnanicus specimens revealed the intense effect of light on its diet resulting in the alteration of its feeding habits towards fish predation and especially Atherina boyeri. On the contrary, the specimens taken with the use of gillnets, from the three lakes, showed a typical omnivorous feeding behavior. The findings of the presently reported study support the assumption that the elevated concentration of fish close to fishing lights alters the feeding behavior of certain species making them predators. Considering that fishing with light is practiced worldwide, this could be of great ecological significance to the ichthyofauna not only of inland waters but also of marine areas, affecting perhaps several commercial species.

The blueline snapper, Lutjanus coeruleolineatus (Rüppell, 1838), is a significant commercial fish species harvested from the traditional fishery in the Sultanate of Oman. Deficient data on this species, however, make the management strategies challenging, especially in fisheries ecology. A total of 978 specimens were obtained from Dhofar Governorate off the coast of the Arabian Sea during the period between February 2015 and March 2016. In total, 296 sectioned otoliths were analyzed and growth was estimated from non-seasonal growth by using von Bertalanffy method. The parameters of von Bertalanffy growth function, total mortality (Z), natural mortality (M), fishing mortality (F), and exploitation rate (E) were determined and compared with those for Lutjanidae fishes elsewhere. The age structure of male fishes was between 1 and 14 years for males while the age of females ranged from 1 to 18 years. Growth rate (K) was 0.21 y–1 and 0.16 y–1 for males and females, respectively. The hypothetical length of female (L∞ = 46 cm) was relatively higher than that of male (L∞ = 42 cm). The natural mortality (M) was 0.296, total mortality (Z) was 0.372, fishing mortality was 0.076, and exploitation rate (E) was estimated as 0.2. The presently reported study is conducted to examine this fish in relation to growth parameters by analyzing otolith structure. The results of the presently reported study will contribute towards planning the regional fishery management policies in Oman.
Short-term change in fish assemblages after the passage of a typhoon in a temperate, coastal bay
Authors: Yagi Mitsuharu
Published: July 2021

To study the effects of a typhoon on a temperate, coastal bay community, the species composition, catch amount, and diversity of epipelagic fish assemblages were investigated. Fish samples were taken from catches of a purse seine fishery in Tachibana Bay, Japan between May and July 2011, covering before and after the passage of a typhoon in the area. Although major changes in total catch amount were not observed before and after the passage of the typhoon, the abundance of the Japanese anchovy, Engraulis japonicus Temminck et Schlegel, 1846, markedly decreased and bycatch of species increased, accompanied by increasing levels of diversity of the fish assemblage. Multivariate analysis showed that community differences before and after the passage were quantitative rather than qualitative. Comparisons in total length frequencies between the two periods indicated that specimens of the species compared were bigger in size for Trachurus japonicus (Temminck et Schlegel, 1844) and smaller for E. japonicus in the “after” period. These results suggest that the passage of the typhoon triggered not only interspecific faunal change but also intraspecific recruitment shifts in and around the bay.
A new record of the brassy chub, Kyphosus vaigiensis (Actinopterygii: Perciformes: Kyphosidae), from the Mediterranean Sea

One individual of the brassy chub, Kyphosus vaigiensis (Quoy et Gaimard, 1825) (41.5 cm TL, 1.27 kg TW), was caught off Annaba, on the eastern coasts of Algeria in December 2013. This circumtropical fish is found for the first time on the south-western Mediterranean coasts. The chronology of its records in the Mediterranean supports the hypothesis of its Atlantic origin.
