<p>BUMDESMA Kecamatan Ngantang adalah Badan Usaha Milik Desa Bersama yang ada di Kecamatan Ngantang. Instansi ini adalah instansi baru yang memiliki usaha berupa <em>playground</em>. Dari awal pembukaan <em>playground </em>hingga terakhir yaitu bulan Juli 2019 pemasukan <em>playground </em>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 <em>playground</em>. Dari permasalahan tersebut maka dikembangkan sistem penyiraman taman berbasis <em>Internet of Things</em> (<em>IOT</em>) untuk menekan biaya pengeluaran BUMDESMA. Sistem manajemen penyiraman taman menggunakan aplikasi yang ditanamkan pada perangkat Android untuk mengontrol sistem yang dibuat dan perangkat <em>embedded </em>untuk melakukan mekanisme penyiraman. Hasil pengujian <em>blackbox </em>menunjukan bahwa hasil uji 100% valid. Pengujian <em>usability </em>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.</p><p> </p><p><em><strong>Abstract</strong></em></p><p><em>BUMDESMA 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.</em></p><p><em><strong><br /></strong></em></p>

With the recent developments in Internet of Things (IoT) and the increase of smartphone users, patient’s health can be monitored without visiting the hospital for medical services. Nowadays, the cost of healthcare is high and insufficient of workforce in the hospital caused the patient unwilling to visit the hospital. The proposed work is to design a monitoring system using sensor and microcontroller to be used by the patients at their place (eg. home). This paper discusses the designing process of the framework. This system will allow the patient to measure their pulse rate and body temperature by using sensors and data collected from the sensor are integrated by using a microcontroller. These acquired patients data could be viewed in mobile application. In addition, the system will provide features such as consultation or chat facility and medical reminder to further improve the feasibility of patients’ health care system.

The concept of cost efficiency has become tremendously popular in data envelopment analysis (DEA) as it serves to assess a decision-making unit (DMU) in terms of producing minimum-cost outputs. A large variety of precise and imprecise models have been put forward to measure cost efficiency for the DMUs which have a role in constructing the production possibility set; yet, there’s not an extensive literature on the cost efficiency (CE) measurement for sample DMUs (SDMUs). In an effort to remedy the shortcomings of current models, herein is introduced a generalized cost efficiency model that is capable of operating in a fuzzy environment-involving different types of fuzzy numbers-while preserving the Farrell’s decomposition of cost efficiency. Moreover, to the best of our knowledge, the present paper is the first to measure cost efficiency by using vectors. Ultimately, a useful example is provided to confirm the applicability of the proposed methods.

The sewage treatment plant of Uppsala was originally built in 1946 and has since then been extended and upgraded several times up to 1972 when the last major upgrading was completed. In 1987 it was decided to renew the treatment plant for at least another 20-30 years of operation and to upgrade the biological process to include nitrogen reduction. A 7 year plan covering some 18 items with a total investment cost of approximately 120 MSEK was set in action during 1987. The aim was to raise the cost efficiency by introducing modern techniques, new machinery, a better working environment and a better understanding of the processes used. The need to keep the plant in operation during reconstruction work has caused difficulties, delays and unforseen costs but a close cooperation between all parties concerned (operators, contractors, engineers and the regional environment administration) has solved most of the problems. Experiences so far include an improved effluent quality, a better cost efficiency, a healthier and more engaged operating staff. A research team has been engaged to develop and introduce a nitrogen reduction scheme in the activated sludge process. This has been a challenging and fruitful experience.

AbstractGlobal deterioration of marine ecosystems, together with increasing pressure to use them, has created a demand for new, more efficient and cost-efficient monitoring tools that enable assessing changes in the status of marine ecosystems. However, demonstrating the cost-efficiency of a monitoring method is not straightforward as there are no generally applicable guidelines. Our study provides a systematic literature mapping of methods and criteria that have been proposed or used since the year 2000 to evaluate the cost-efficiency of marine monitoring methods. We aimed to investigate these methods but discovered that examples of actual cost-efficiency assessments in literature were rare, contradicting the prevalent use of the term “cost-efficiency.” We identified five different ways to compare the cost-efficiency of a marine monitoring method: (1) the cost–benefit ratio, (2) comparative studies based on an experiment, (3) comparative studies based on a literature review, (4) comparisons with other methods based on literature, and (5) subjective comparisons with other methods based on experience or intuition. Because of the observed high frequency of insufficient cost–benefit assessments, we strongly advise that more attention is paid to the coverage of both cost and efficiency parameters when evaluating the actual cost-efficiency of novel methods. Our results emphasize the need to improve the reliability and comparability of cost-efficiency assessments. We provide guidelines for future initiatives to develop a cost-efficiency assessment framework and suggestions for more unified cost-efficiency criteria.

The five freedoms and, more recently, the five domains of animal welfare provide internationally recognised frameworks to evaluate animal welfare practices which recognise both the physical and mental wellbeing needs of animals, providing a balanced view of their ability to cope in their environment. Whilst there are many techniques to measure animal welfare, the challenge lies with how best to align these with future changes in definitions and expectations, advances in science, legislative requirements, and technology improvements. Furthermore, enforcement of current animal welfare legislation in relation to livestock in Australia and the reliance on self-audits for accreditation schemes, challenges our ability to objectively measure animal welfare. On-animal sensors have enormous potential to address animal welfare concerns and assist with legislative compliance, through continuous measurement and monitoring of an animal’s behavioural state and location being reflective of their wellbeing. As reliable animal welfare measures evolve and the cost of on-animal sensors reduce, technology adoption will increase as the benefits across the supply chain are realised. Future adoption of on-animal sensors by producers will primarily depend on a value proposition for their business being clear; algorithm development to ensure measures are valid and reliable; increases in producer knowledge, willingness, and trust in data governance; and improvements in data transmission and connectivity.

Fault Proneness

Nowadays, modern applications are developed using components written in different programming languages and technologies. The cost benefits of reuse and the advantages of each programming language are two main incentives behind the proliferation of such systems. However, as the number of languages increases, so do the challenges related to the development and maintenance of these systems. In such situations, developers may introduce design smells (i.e., anti-patterns and code smells) which are symptoms of poor design and implementation choices. Design smells are defined as poor design and coding choices that can negatively impact the quality of a software program despite satisfying functional requirements. Studies on mono-language systems suggest that the presence of design smells may indicate a higher risk of future bugs and affects code comprehension, thus making systems harder to maintain. However, the impact of multi-language design smells on software quality such as fault-proneness is yet to be investigated. In this article, we present an approach to detect multi-language design smells in the context of JNI systems. We then investigate the prevalence of those design smells and their impacts on fault-proneness. Specifically, we detect 15 design smells in 98 releases of 9 open-source JNI projects. Our results show that the design smells are prevalent in the selected projects and persist throughout the releases of the systems. We observe that, in the analyzed systems, 33.95% of the files involving communications between Java and C/C++ contain occurrences of multi-language design smells. Some kinds of smells are more prevalent than others, e.g., Unused Parameters , Too Much Scattering , and Unused Method Declaration . Our results suggest that files with multi-language design smells can often be more associated with bugs than files without these smells, and that specific smells are more correlated to fault-proneness than others. From analyzing fault-inducing commit messages, we also extracted activities that are more likely to introduce bugs in smelly files. We believe that our findings are important for practitioners as it can help them prioritize design smells during the maintenance of multi-language systems.

This article presents a simple wideband rectangular antenna in foldable and non-foldable (printed circuit board (PCB)) structures for Internet of Things (IoT) applications. Both are simple structures with two similar rectangular metal planes which cover multiple frequency bands such as GPS, WCDMA/LTE, and 2.4 GHz industrial, scientific, and medical (ISM) bands. This wideband antenna is suitable to integrate into the short- and long-range wireless applications such as the short-range 2.4 GHz ISM band and standard cellular bands. This lowers the overall size of the product as well as the cost in the applications. In this article, the configuration and operation principle are presented as well as its trade-offs on the design parameters. Simulated and experimental results of foldable and non-foldable (PCB) structures show that the antenna is suited for IoT applications.
