Kepastian Hukum Pemegang Hak Atas Tanah di Kawasan Hutan (Analisis Putusan Mahkamah Konstitusi Nomor 45/puu-ix/ 2011 Dihubungkan dengan Putusan Mahkamah Agung Nomor 47 P/hum/2011)

The result of the research showed that the Ruling of the Constitutional Court No.45/2011 has judicially reinforced legal certainty for the people entitled to the land rights in the forest area, but it is factually not implemented yet. The Rulling of the Supreme Court No. 47/2011 has also judicially provided legal certainty for the people entitled to the land rights in the forest area, especially in Nort Sumatera. However, the Decree of the Minister of Forestry does not factually accommodate the interest of the people entitled to the land rights. In other words the Decree actually has not yet provided legal certainty for the people entitled to the land rights in the forest area

Implementasi Media Pembelajaran Teknik Pengkodean Barcode Berbasis Multimedia dalam Meningkatkan Kualitas Kegiatan Belajar Mengajar

Science information and communication technology, especially the use of computers is growing rapidly every year. One is the application in multimedia. Multimedia has changed the way people interact with computers. Multimedia applications can quickly attract the attention of someone, to be used according to their individual needs. Today, many multimedia functions involved in various fields of activity. Not only in entertainment but also used in the learning process. Media multimedia-based learning is one application that can be used for students in education today. Because it can provide an interactive learning materials and supported various aspects such as audio, video, animation, text, and graphics. Software development methods of learning media using the Multimedia Development Lifecycle. Multimedia Development is carried out by eleven stages, namely defining the problem, feasibility studies, system requirements analysis, design a concept, designing the content, designing text, graphics designing, producing system, test system, using the system, maintaining the system. Application of instructional media barcode-based multimedia coding techniques to assist teachers in improving the quality of teaching and learning activities so that it becomes more attractive for students

The Effectiveness of Combined Anaerob - Aerob Biofilters and Phytoremediation Using Pistia Stratiotes for Reducing TSS and Ammonia Content in Sago Industrial Liquid Waste

The sago industrial liquid waste is rich in TSS and ammonia and thus need to be processed before being flown to environment. A study aims to reduce the TSS and ammonia in that waste has been conducted in January - April 2017. The sago liquid waste (135 liter) was kept in an anaerob tank (with gravel, sand and palm fiber media) for 10 days. The waste was then flown to an aerobic tank (with charcoal and palm fiber media) for 5 days and finally the waste was treated in a phytoremediation pond that was completed by Pistia stratiotes for 15 days. By the end of the experiment, the TSS reduced from 376 mg/L to 30 mg/L (the effectivity was 88.84% - 92.02%), while the ammonia reduced from 11.82 mg/L to 0.01 mg/L (the effectivity was 48.48% - 99.7%). Other water quality parameters such as pH and DO were improved. The treated waste was used for rearing Cyprinus carpio fingerlings for 7 days and survival rate of the fish was 93%. Based on data obtained, it can be concluded that the combination of anaerob-aerob biofilters and phytoremediation using P. stratiotes is effective to reduce the TSS and ammonia content in the sago industrial liquid waste

Pertumbuhan Akar Pada Perkecambahan Beberapa Varietas Tomat Dengan Pemberian Polyethylene Glikol (Peg) Secara in Vitro

Tomato plants originated from Mexico to Peru region. At the present time the tomato hasbecome more developed, modern cultivars or hybrids can grow well and produce the climate ismuch different from the place of origin. This study aims to create drought tolerant plant of tomatovarieties. The research has done in Tissue Culture Laboratory Fakultuty Agriculture UnivercityNort Sumatera, Medan since Juli-September 2012. Using a completely randomized design with twofactors, that is Polyethylene Glicol (PEG) (0,5,10,15,20%) and Tomato varieties (TO-244, Niki,Kartika, Mio, Super Hawai) with four replications. Observation variable is living root forminginitiation, total of root, and high of roott. The result of research has shown that PEG is significantfor root forming initiation and high of root, but not significant for total of root

Implementation of Business Intelligence Using Highlights in the YII Framework Based Attendance Assessment System

Attendance information conducted by students can now be easily accessed by a supervisor. However, there are 3 (three) difficulties faced by supervisors, one of which is presenting information with tables requiring considerable time and very high accuracy to measure the comparison of information contained within it. In order to facilitate the supervisor in recording and measuring attendance of student tutoring students handled, the Attendance Rating system will present information in the form of graphics using Highchart. Presentation of information in the form of a graph on Attendance Assessment will present information in the form of Nim (Student Registration Number), supervisor, and guidance time. Information on the guidance time in the graph can be used as a comparison to measure the level of student activity in following the guidance. The Attendance Rating System uses the YII Framework-based website because it is also easy to develop web applications and the YII Framework has a good level of security. In this study, there are 5 (five) advantages and 1 (one) deficiency in the Attendance Assessment system. With this research, it is expected that the Attendance Assessment system can improve the quality of student attendance in the tutoring process at Raharja College

The Effectiveness of Al2SO4, CaO and Crude Tannin Extract Originated From Averrhoa Bilimbi Wood to Improve the Quality of Peat Water

Peat water is categorized as low quality water as it has high organic matter, low pH, high TDS and turbidity and brownish colored. Crude tannin extract has been used for improving the peat water, but there is no information on the use of Averrhoa bilimbi tannin extract in improving the quality of the water. To understand effectiveness of the A. bilimbi tannin in improving the peat water quality, a study has been conducted in May – October 2015. There was a CRD method applied, with 4 treatments, P0 (control, without tannin extract), P1(10 mlL-1), P2(20 mlL-1) and P3(30 mlL-1). In each treatment unit, 8 liters peat water was added with Al2SO4 (2 grL-1) and CaO (2.7 grL-1) and then was added with various dosages of tannin extract. The treated water was kept for 3 hours and the water quality parameters were measured. The treated water was then used to rear Cyprinus carpio. Results shown that the treated water quality was improved, there was degradation in organic matter content, turbidity and colour, while pH, DO and TDS was increase. The best treatment was obtained in P1, as the organic matter decrease, from 1,145.5 to 151.97 mg/L, the turbidity decrease, from 1,005.66 to 26 NTU and color also decrease, from 29,000.33 to 389 PtCo. The highest survival rate of C. carpio after being reared for 4 days was also found in the P1 treated water, that was 97%. Based on the data obtained, it can be concluded that the crude tannins extracts from A. bilimbi wood is effective to improve the quality of peat water

Analisis Pilihan (Preferensi) Masyarakat terhadap Permintaan Helm di Kota Pekanbaru
