The Role of Social Media in Corporate Governance
Authors: Ang James S. , Hsu Charles , Tang Di , Wu Chaopeng 
Published: March 2021

ABSTRACT
We examine whether social media criticisms posted by small investors can predict subsequent firm acquisition decisions. Specifically, we use textual analysis to examine the internet stock message board postings of 303 value-reducing acquisition attempts. Our empirical evidence shows that small investors' negative postings are able to predict a potential acquirer's subsequent decision to withdraw its attempt. We further find that this predictive ability increases with the information quality of postings, and that the predictive information extracted from social media is incremental to that captured by proposal announcement returns, conventional media coverage, analyst reports, and institutional investors' responses related to the proposed acquisition. Finally, we show that message board criticisms are also able to predict governance outcomes beyond acquisition decisions. Overall, our results are consistent with the notion that social media play a role in corporate governance by gathering crowd wisdom and uncovering additional value-relevant information.

The Effect of Receptie Theory on Legal Concept of “Adat Barenti Lako Syara’, Syara Barenti Lako Kitabullah”
Authors: Dianto Dianto 
Published: March 2021

Receptie theory of Snouck Hurgonje's thought requires that Islam be valid if it has been perceived by customary law. The perception of a starting point between Islamic law and customary law was mediated by Syahrial Abbas with his split bamboo theory. However, the concept of "Adat Barenti Lako Syara’, Syara Barenti Lako Kitabullah" requires that customary law be valid or accepted if it has been validated by Islamic law. Employing a normative method and a philosophical approach, this paper examined the effect of the receptie theory on the legal concept of "Barenti Lako Syara', Syara Barenti Lako Kitabullah". This paper concluded that the receptie theory could not influence the legal concept of "Adat Barenti Lako Syara’, Syara Barenti Lako Kitabullah" because customary law can be applied if it has been verified by Islamic law.

Abstract

OBJECTIVE
To determine the dose of coenzyme Q10 (CoQ10) needed to achieve at least a 3-fold increase in plasma CoQ10 concentration in dogs with myxomatous mitral valve disease (MMVD) and congestive heart failure (CHF).

ANIMALS
18 dogs with CHF due to MMVD and 12 healthy dogs.

PROCEDURES
In a randomized, double-blinded, controlled trial, dogs with MMVD were given 50 or 100 mg of water-soluble CoQ10 (ubiquinone; total daily dose, 100 mg [n = 5] or 200 mg [6]) or a placebo (7), PO, twice a day for 2 weeks in addition to regular cardiac treatment. Plasma CoQ10 concentration was measured in dogs with MMVD before (baseline) and at various time points after supplementation began and in healthy dogs once. Concentrations were compared among and within groups.

RESULTS
No significant difference in median baseline plasma CoQ10 concentration was detected between healthy dogs and dogs with MMVD. Fold increases in plasma CoQ10 concentrations ranged from 1.7 to 4.7 and 3.2 to 6.8 for individual dogs in the 100-mg and 200-mg groups, respectively. The change in plasma CoQ10 concentration after supplementation began was significantly higher than in the placebo group at 4 hours and 1 and 2 weeks for dogs in the 200-mg group and at 1 and 2 weeks for dogs in the 100-mg group.

CONCLUSIONS AND CLINICAL RELEVANCE
A daily CoQ10 dose of 200 mg was sufficient to achieve at least a 3-fold increase in plasma CoQ10 concentration and may be used in CoQ10 supplementation studies involving dogs with CHF due to MMVD.

Abstract

OBJECTIVE
To assess the effect of horseshoes with and without traction adaptations on the gait kinetics of nonlame horses during a trot on a concrete runway.

ANIMALS
5 nonlame adult light-breed horses.

PROCEDURES
Kinetic data were obtained for each horse when it was trotted across a force platform within a concrete runway unshod (control) and shod with standard horseshoes; standard horseshoes with high profile–low surface area calks, with low profile–high surface area calks, and coated with a thin layer of tungsten carbide (TLTC); and plastic-steel composite (PSC) horseshoes. Kinetic data were obtained for the control treatment first, then for each of the 5 shoe types, which were applied to each horse in a random order. Kinetic variables were compared among the 6 treatments.

RESULTS
Body weight distribution did not differ among the 6 treatments. Compared with the control, the greatest increase in forelimb peak vertical force was observed when horses were shod with PSC shoes. In the hind limbs, the greatest increase in peak braking force was observed when horses were shod with PSC shoes, followed by the TLTC and low profile–high surface area calked shoes. The PSC shoes yielded the greatest coefficient of friction in both the forelimbs and hind limbs. Stance time was longest when horses were shod with standard shoes.

CONCLUSIONS AND CLINICAL RELEVANCE
Results suggested that PSC and TLTC shoes provided the best hoof protection and traction and might be good options for horses that spend a large amount of time traversing paved surfaces.

Published: March 2021

Udang merupakan salah satu komoditas unggulan bagi Indonesia dari sektor perikanan. Budidaya udang pada tambak, perlu memperhatikan kualitas air. Kualitas air yang perlu diperhatikan dalam pertumbuhan dan kehidupan udang adalah perubahan temperatur, kadar garam, kebutuhan oksigen dan tingkat keasaman atau kandungan pH. Pemantauan secara manual membutuhkan waktu, tenaga dan biaya yang jauh lebih besar karena harus ada petugas yang berkeliling kolam untuk melakukan pengukuran. Dengan Internet of Things (IoT) yang dikembangkan dalam penelitian ini proses monitoring tersebut dapat dilakukan dengan cepat atau realtime. Model yang dikembangkan terdiri dari perangkat node yang dipasang pada setiap kolam dan masterboard untuk pengumpulan data. Sensor yang dipasang pada setiap node adalah sensor salinitas air, sensor pH dan sensor suhu. Nilai salinitas, pH dan suhu selain ditampilkan pada perangkat penampil yang ada pada node juga dikirimkan ke masterboard. Hasil penelitian menunjukkan perangkat sensor bekerja dengan baik, data salinitas air, pH dan suhu dapat ditampilkan pada node. Ujicoba komunikasi data juga dapat berkerja dengan baik yang ditunjukkan dengan data dapat dikirimkan ke masterboard dengan delay 1 detik karena data masuk secara bergantian atau serial. Masterboard dapat bekerja untuk mengirimkan data ke basis data cloud firebase untuk selanjutnya data ditampilkan pada aplikasi monitoring yang telah dikembangkan. AbstractShrimp is one of the leading commodities for Indonesia from the fisheries sector. Shrimp farming, needs to pay attention to pond water quality. The water quality parameter that needs to be considered in the growth and life of shrimp is temperature, salinity, and pH. The farmer usually, monitor the shrimp pond manually that requires much greater time, effort and cost. The process can be automated with the Internet of Things (IoT) developed in this research. The model developed consists of a set of nodes installed in each pond and a masterboard for data collection. The sensors installed at each node are water salinity sensors, pH sensors and temperature sensors. The Salinity, pH and temperature score besides being displayed on the display device at each node, it is also sent to the masterboard through data communication. The results show that the sensor and data communication devices can work well with low latency (1 s) since the data received serially. Masterboard can work to send data to the Firebase cloud database so that the data may displayed in the monitoring application that has been developed.

BUMDESMA Kecamatan Ngantang adalah Badan Usaha Milik Desa Bersama yang ada di Kecamatan Ngantang. Instansi ini adalah instansi baru yang memiliki usaha berupa playground. Dari awal pembukaan playground hingga terakhir yaitu bulan Juli 2019 pemasukan playground mengalami penurunan dikarenakan rusaknya rumput taman selama musim kemarau. Permasalahan yang dialami BUMDESMA adalah pemeliharaan rumput gajah mini untuk taman memerlukan metode penyiraman khusus namun BUMDESMA belum mampu menggunakan jasa penyiraman untuk menyiram taman playground. Dari permasalahan tersebut maka dikembangkan sistem penyiraman taman berbasis Internet of Things (IOT) untuk menekan biaya pengeluaran BUMDESMA. Sistem manajemen penyiraman taman menggunakan aplikasi yang ditanamkan pada perangkat Android untuk mengontrol sistem yang dibuat dan perangkat embedded untuk melakukan mekanisme penyiraman. Hasil pengujian blackbox menunjukan bahwa hasil uji 100% valid. Pengujian usability menunjukan nilai lebih dari kriteria minimum penelitian dengan nilai 72 yang berarti bahwa aplikasi dapat diterima oleh pengguna. Dari hasil pengujian efisiensi biaya menunjukan bahwa penggunaan sistem penyiraman dalam jangka panjang dapat mengurangi biaya pengeluaranan BUMDESMA dibanding penggunaan jasa penyiraman profesional. AbstractBUMDESMA Kecamatan Ngantang is a Joint Village-Owned Enterprises located in Ngantang District, Malang, East Java. This is a new agency that has a playground as one of the core businesses. Along from the beginning of the playground operates until the end of July 2019, playground revenue has gradually decreased. This issue arises due to the bad condition of the grass on the playground causing local people are not willing to visit that place. The playground's grass requires special watering treatment but BUMDESMA is the lack of income so they cannot afford to pay the professional grass maintenance services to actively watering the playground grass. From these problems, We proposed an IOT based garden watering system to reduce BUMDESMA expenditure costs. The garden watering management system uses a mobile application as a user interface to control the system and embedded devices for the watering mechanism. Blackbox testing of the proposed system shows that all the functional requirements are 100% valid. Usability testing shows a value of 72 which is more than the minimum threshold of usability criterion means that the application is acceptable to users. The results of cost-efficiency testing show that the proposed water systems can reduce the cost when compared to using professional watering services.
