Why Do Information Technology Projects Fail?
No full textAbstractWith developing technological possibilities, IT projects are becoming increasingly ambitious in both goals and scale. Although technology itself is enabling easy management of project execution, failure can still occur, particularly with respect to an ample number of unique projects. It is argued here that the ampleness and uniqueness of projects provide criteria for such projects to be treated differently from smaller-scale enterprises of the same type. Gaps can be identified in the literature with regards to exact definitions of project success and failure. It is proposed that three main issues can impact a project's ecosystem and determine its failure, namely, uncertainty, volatility, and unknowns. Based on these aspects, future project performance can be estimated and correspondingly managed. At the same time, retrospective assessment of success or failure may be made rigorous based on exact definitions. Two case studies of major technological projects are presented and discussed here as examples of theory application
Pengaruh Pestisida Alami Untuk Membasmi Hama Pada Tanaman Cabai di Rumah Petani Karangjati
No full textAbstrakTanaman cabai merupakan tanaman yang banyak dijumpai di Indonesia. Petani melakukan budidaya tanaman cabai karena minat dari masyarakat akan cabai sangat tinggi. Namun petani selalu dihadapkan dengan permasalahan hama yang sering menyerang tanaman cabainya. Kebanyakan petani menggunakan pestisida kimia untuk memberantas hama pada tanamannya. Memang cepat dalam memberantas hamanya, namun kurang baik dalam segi lingkungan dan kesehatan manusia. Untuk itu, penulis akan memberikan alternatif untuk memberantas hama yang ada ditanaman tanpa adanya efek samping baik tanaman itu sendiri maupun ekosistem disekitarnya. Metode yang digunakan dalam kegiatan pengabdian masyarakat ini yaitu observasi dan wawancara. Pembuatan pestisida alami ini menjadi salah satu alternatif karena ramah lingkungan dan aman untuk kesehatan manusia. Pestisida alami ini terbuat dari kotoran kambing, dan rempah-rempah yang sering digunakan ibu dalam memasak. Pestisida ini disosialisasikan kepada masyarakat khususnya yang bergerak di bidang pertanian. Untuk mengetahui efektif tidaknya penggunaan pestisida alami dalam memberantas hama dilakukan dengan pengamatan setelah penyemprotan pestisida alami secara rutin untuk tanaman cabai yang terserang hama. Sehingga dari pengamatan ini didapati penggunaan pestisida dari kegiatan pembuatan pestisida alami, penyemprotan pestisidanya ke tanaman yang terdapat hama, penyemprotan dilakukan sehingga didapati dari hasil pengamatannya pestisida ini cukup efektif dalam memberantas hama yang terdapat di tanaman cabai. Dari hasil pengamatan didapati penyemprotan pestisida alami secara rutin dapat meminimalisir penyebaran hama ditanaman. Kata Kunci: Pestisida Alami, Hama, Tanaman Cabai. AbstractChili plants are plants that are often found in Indonesia. Farmers cultivate chili plants because the public’s interest in chili is very high. However, farmers are always faced with the problem of pests that often attack their chili plants. Most farmers use chemical pesticides to eradicate pests on their crops. It is fast in eradicating the pests, but it is not good in terms of the environment and human health. For this reason, the author will provide an alternative to eradicate pests that exist in plants without any side effects, both the plant itself and the surrounding ecosystem. The method used in this community service activity is observation and interviews. Making natural pesticides is an alternative because it is environmentally friendly and safe for human health. This natural pesticide is made from goat dung, and spices that mothers often use in cooking. These pesticides are socialized to the public, especially those engaged in agriculture. To find out whether the use of natural pesticides is effective in eradicating pests is carried out by observing after spraying natural pesticides on a regular basis for chili plants that are attacked by pests. So from this observation it was found that the use of pesticides from the activities of making natural pesticides, spraying was carried out so that it was found from the observations that these pesticides were quite effective in eradicating pests found in chili plants. From the observations, it was found that regular natural pesticide spraying can minimize the spread of pests on plants.Key Word: Natural pesticides, pests, chili plants
Taming Foreign Exchange Derivatives Markets? Speculative Finance and Class Relations in Brazil
No full textThis article provides a critical interrogation of the Brazilian tax on foreign exchange derivatives deployed between 2011 and 2013. It analyses the drivers of the policy‐making process that led to implementation of the measure, locates it within the broader policy response regarding the management of cross‐border capital flows and speculative finance, and assesses its political economy significance in light of class dynamics. The author makes three arguments. First, this innovative policy tool must be interpreted in terms of the emergence of a specific form of state power allowing for the continuation of finance‐led strategies of accumulation, while mitigating some of their worst consequences. Second, this form of state power internalizes the subordinate positionality of Brazil in the global financial and monetary system. Third, while financialization processes have eroded the efficiency of a number of policy tools, this policy experiment demonstrates the possibility of regulating complex financial markets, provided that appropriate resources are dedicated to the task, and that there is the political will to do so. The article concludes by discussing theoretical implications, for how to theorize state and financialization, as well as political implications
Eksplorasi Material Alami: Bahan Anti Semut Untuk Produk Dinnerware
No full textAktivitas makan merupakan aktivitas primer sehari-hari yang tak lepas dari kerawanan permasalahan gangguan semut. Semut yang datang tersebut ada kemungkinan membawa bakteri yang dapat mengkontaminasi kualitas makanan. Salah satu cara yang sering digunakan untuk mengantisipasi semut adalah menggunakan bahan kimia seperti kapur semut atau obat semprot. Namun penggunaan bahan kimia mengandung potensi bahaya, terutama jika bahan tersebut tidak termasuk kategori food grade. Adapun cara lain untuk mengantisipasi datangnya semut adalah menggunakan bahan alami seperti kayu manis, cengkeh, kopi dan teh. Bahan-bahan tersebut dapat mengacak sistem sensor pada semut untuk menemukan makanan. Pada penelitian ini penggunaan bahan kayu manis dan cengkeh diekplorasi menjadi produk dinnerware, karena produk dinnerware anti semut masih belum banyak dikembangkan. Metode yang digunakan pada penelitian ini adalah metode eksperimen untuk menemukan komposisi yang tepat agar diperoleh dinnerware yang rigid. Selanjutnya, dilakukan eksplorasi bentuk. Akhirnya dilakukan uji ketahanan produk terhadap semut untuk mengetahui seberapa lama dan seberapa kuat produk dinnerware anti semut alami ini dapat mengantisipasi datangnya semut.===================================================
Dining activity is a primary daily activity that cannot be separated from the Impact of the disorder by ants. The ants are likely to carry bacteria that can contaminate the quality of food. One way that is often used to anticipate ants is to use chemicals such as ant lime or spray insecticide. However, the use of chemicals containing potential danger, especially the ingredients Not in the category of food grade. But another way to anticipate the coming of ants is to use natural ingredients such as cinnamon, cloves, coffee, and tea. These materials will scramble of the sensor system at the ant to find food. In this study, the use of cinnamon and clove ingredients was explored into dinnerware products because ant repellent dinnerware products have not yet been widely developed. The method used in this study is an experimental method to find the right composition to obtain a rigid dinnerware. The next step is the author doing form exploration. Finally, a product endurance test is conducted on ants to find out how long and how strong this natural ant repellent dinnerware product can anticipate of ants
Assessment of primary brain lymphoma using multimodal magnetic resonance imaging and proton magnetic resonance spectroscopy
No full textObjectives: The primary lymphoma of the central nervous system is a cancer rare. The diagnosis of this tumoral entity must be considered as an emergency considering the therapeutical involved. Therefore, we report this entity while reporting diagnostic challenges. Patients and Methods: Unfortunately, the conventional clinical and imaging signs can be confusing and might contribute to delay the diagnosis process of potentially curable pathological entity. The diagnosis confirmation in immunocompetent patients is based on a stereotaxic biopsy. Results and Conclusion: In this paper, we report a case illustrating the contribution of multimodal imaging including diffusion-weighted magnetic resonance imaging (MRI), diffusion tensor MRI, perfusion MRI, and proton MR spectroscopy to the diagnostic approach of the atypical primary lymphoma of the central nervous system.</jats:p
