ANALISIS KEBUTUHAN AIR DAERAH IRIGASI DESA SUMBERGEDE KECAMATAN SEKAMPUNG KABUPATEN LAMPUNG TIMUR
Get PDFJumlah air irigasi yang masuk ke lahan pertanian dapat diketahui melalui debit air yang mengalir. Data debit air merupakan informasi yang sangat penting bagi pengelola sumber daya air, karena debit aliran puncak diperlukan untuk merancang bangunan pengendali banjir, sedangkan debit aliran kecil diperlukan untuk perencanaan alokasi (pemanfaatan) air untuk berbagai macam keperluan, terutama pada musim kemarau panjang. Usaha meningkatkan produktivitas pertanian dan ketahanan pangan, adalah dengan pemenuhan kebutuhan air, karena air mempunyai peranan yang sangat penting dalam produktivitas pertanian. Banyak usaha yang dilakukan untuk memenuhinya, antara lain dengan pemanfaatan sumber air, baik sumber air permukaan seperti sungai dan waduk, ataupun sumber air tanah dalam dengan sumur bor. Selain kebutuhan akan air, tanaman juga membutuhkan tempat untuk tumbuh (lahan atau sawah). Sawah dan lahan yang baik untuk pertanian ialah tanah yang mudah dikerjakan (dikelola) yang bersifat produktif dan subur serta cukup akan kebutuhan air.Berdasarkan hasil penelitian dan perhitungan yang dilakukan, debit air rata-rata yang masuk pada saluran irigasi KBH 14 A Kiri masih lebih besar dari nilai kebutuhan air sawah, namun kenyataannya beberapa areal persawahan masih kekeringan, ini menandakan kalau air irigasi tidak sampai di lahan persawahan tersebut. Penyebab utama hal tersebut adalah pendistribusiannya yang kurang merata, berarti kordinasi antara para petugas dengan petani harus lebih diperbaik

Desain dan analisis pengaruh parameter PI dan variasi kecepatan pada respon sistem kontrol arah hadap prototype kendaraan listrik
Get PDFElectric vehicles are alternative vehicles that carry energy efficient. At this time the dominant vehicle uses ordinary wheels so that it will become an obstacle in the maneuver function that requires movement in various directions. With mechanum wheels the vehicle can move in various directions by adjusting the direction of rotation of each wheel. The problem is choosing the right control system for the control system needed by the vehicle. The purpose of this study is to determine and analyze the effect of variations in the value of PI (Proportional Integral) and speed of the vehicle to the stability response of the system to control the direction of prototype electric vehicles. This study method is an experiment that is by giving a treatment, then evaluating the effects caused by the research object. The results of this study can be concluded that the variation of PI constant values and speed variations have an effect on the stability parameters of the system, namely rise time, settling time, overshot, and steady state error. To get the best system stability response results can use the constant value PI Kp = 2; and Ki = 17; where the stability response of the system for direction control at each speed condition has a fairly good value with a fast rise time, fast settling time, small overshot and a small error steady state compared to other PI constant values in this study.Keywords: mechanum wheel, PI control, direction, prototype, system stabilit
COMPARATION OF INTERNATIONAL COPYRIGHT LAW IN INDONESIA COUNTRIES - HONGKONG - SINGGAPORE - MALAYSIA AND THAILAND VIEWED FROM THE ASPECT OF CRIMINAL SANCTIONS ON CORPORATION
Get PDFCopyright Law No. 28 of 2014 concerning Copyright in Indonesia has been ratified since 2014, and came into force and can be implemented or operationalized after two years later in 2016. The main problems that arise with the application of the Copyright Act Cipta in Indonesia there are other issues related to juridical issues regarding the formulation of criminal provisions and related to the problem of unclear issues regarding the formulation of criminal offense qualifications or unclear violations, determination of the subject of corporate law is not regulated, corporate criminal sanctions are not regulated, formulation of sanctions for sanctions that are not clear, against criminal offenses in the Copyright Act. Juridical problems in the Copyright Act in Indonesia will have an impact on the implementation and operation of the current and future Copyright Laws. Furthermore, a discussion on the comparative policy formulation of criminal provisions against corporate legal entities in Indonesia with the Copyright Act in other countries. Copyright Regulations, except for the Indonesian state, do not regulate criminal sanctions against corporations, while Malaysia, Singgapura, Malaysia, Hong Kong and Thailand all regulate criminal sanctions against corporations and include them as strict legal subjects in their material and formal laws. That, proving that, copyright infringement in the eyes of foreign countries is considered important and crucial, so it needs to be regulated in the policy formulation of criminal provisions in that country in order to protect copyright holders, related rights and performers of copyright. Unlike the Copyright Act in Indonesia, only regulates the legal subject of individuals, while corporate legal entities are only referred to in the juridical definition in general provisions of the Copyright Act only, but the provisions in the formulation policy of criminal provisions are not clearly and clearly regulated. Though it is clear that criminal liability sanctions between individuals with criminal sanctions corporate legal entities differ in the imposition of sanctions. Corporations are legal entities created by law. The body that it creates consists of a "corpus" that is, its physical structure and into it the law of entering "animus" which makes the body have a personality. Because the legal entity is a legal creation, except for its creator, its death is also determined by law. To identify how the forms of legal entity are called corporations in general. The corporation has an important characteristic namely; is an artificial legal subject that has a special legal position, has a limited life span, obtains power from the state to carry out certain business activities, owned by shareholders. Shareholder responsibility for corporate losses is usually limited to the shares he owns. Furthermore, to support the objectives of this study, the paradigm used in this study is the post-positivism paradigm. Post-positivism paradigm wants to prove everything is based on reality that can be built based on experience, observation, researchers are neutral towards the object of research, even though researchers holding this paradigm remain neutral towards the object of research, but he wants to examine what actually happens from things that actually as if for sure. The post-positivism paradigm ontologically conceptualizes reality as it really is, but it is realized that there are actually many factors that influence that reality. Consequently, ontologically the post-positivism paradigm conceptualizes the law as a set of rules that apply in society whose behavior will be influenced by economic, political, cultural, and other factors. Epistemologically, researchers sit themselves impersonal, separate from the object of research. The researcher's position on the object of research is neutral and impartial

Optimasi nilai keausan pahat dan kekasaran permukaan benda kerja terhadap parameter pemesinan milling dengan benda kerja magnesium menggunakan kombinasi metode taguchi dan grey relational analysis
Get PDFThe Taguchi method is widely used to determine the optimal quality of a process with a single response. While for multi-response cases, Grey Relational Analysis (GRA) and Principal Component Analysis (PCA) are widely used. With multi-phone GRA, it can be simplified into one single response. Tool wear and surface roughness of the workpiece in the milling machining process is affected by the diameter of the tool, depth of feed, spindle speed, and feeding speed. This study examines the response of tool wear and work surface roughness with three levels and four factors. For tool diameters, using 6.8 mm and 10 mm. The depth of feed used 1; 1,5 mm and 2 mm. Spindle speeds at 910, 1280, and 1700 rpm. While the feeding speed is 75 mm/minute, 145 mm/minute, and 220 mm/minute. Optimal results obtained in conditions of 6 mm tool diameter with 1,5 mm depth of feeding, spindle speed of 1280 rpm, and feeding speed of 75 mm/minute. The optimal response obtained is 0,059 mm for tool wear and 0,364 μm for work surface roughness. The significant factor influencing is the feeding speed which influences 76,14 %.Keywords: Grey Relational Analysis, Principal Component Analysis, Taguchi Method, Milling, Tool Wear, Roughnes

Pengaruh Gaya Kepemimpinan Otoriter pada Usia Remaja
Get PDFGaya kepemimpinan otoriter adalah gaya seorang pemimpin yang memusatkan segala keputusan dan kebijakan diambil dari dirinya tanpa harus bertanya atau melihat bagaimana para anggota bawahannya. Segala semua keputusan atau melakukan kegiatan pada gaya otoriter ini seepenuhnya dikontrol oleh pemimpin. Metode yang digunakan pada penelitian ini adalah metode library research atau biasa disebut dengan studi kepustakaan. Penelitian ini bertujuan untuk mengetahui pengertian dari kepemimpinan dan gaya kepemimpinan otoriter, untuk mengetahui kebutuhan-kebutuhan pada anak usia remaja, pengaruh gaya kepemimpinan otoriter terhadap anak usia remaja, untuk mengetahui sisi positif dan negatif dari kepemimpinan otoriter bagi anak usia remaja, serta untuk mengetahui pengaruh jangka pendek dan jangka panjang dari penerapan pola asuh otoriter bagi anak usia remaja. Orang tua dan guru yang mendidik anaknya dengan gaya otoriter ini cenderung lebih mendikte anak dan kurang memiliki hubungan yang erat terhadap anak atau peserta didik tersebut. Sangat jarang dampak positif yang dihasilkan dari gaya kepemimpinan otoriter ini, kecuali orang tua dalam memerintah dan menghukum anak tersebut dapat memberikan alasan mengapa anak tersebut mendapatkan hukuman seperti itu
PERGESERAN NILAI-NILAI DEMOKRASI: SEBUAH REFLEKSI PASCA BERGULIRNYA DANA DESA
Get PDFThe purpose of this research is to look at the shift of the village community in terms of democracy, which was originally from a consensus in determining the village head to be a practical political practice for the village community, without thinking about the consequences that will be felt in the future. The revolving of village funds for development and community empowerment is one factor shifting democratic values. The method in this research is normative juridical. This research shows that developing democratic life in the village is an obligation for the village as a consequence of autonomy, where in the concept of autonomy the given authority is interpreted as a responsibility to accelerate the welfare of the community through improving the democratic system. However, the principles of democracy applied in villages must be developed in accordance with the principles of recognition and subsidiarity based on the socio-cultural village. So that the implementation and development of democratic life in the village is not only done for the sake of democracy itself, but is oriented towards the collective progress of the village community
