When the teacher or a student is absent, then the implementation of learning would be problematic. Web community is a media sharing and communication between users. By adding several amenities such as private Chat, Public Chat, Forum, and video sharing will be used as a means of learning process. The author will conduct research to harness advances in internet technology for Developing web-based community to support the process of Interactive Distance Learning. System development method used is the System Development Life Cycle (SDLC). The purpose of this research is the formation of a web community that can be used as a means of sharing information, discussion and delivery of content on line, so that the learning process can be done at any time, even without the presence of teacher or student in the same place.

School students or madrasah students are generally 13-15 years old. Madrasah schools are a transition period from childhood to the world of adolescence. The period of MTS is a critical period for student education because at this time the transition from childhood. At present education is very much influenced by technological developments that provide a variety of conveniences so that it influences students' thinking, so schools must start working hard and pay attention to the education programs and methods used in transferring knowledge from teaching staff to students. The use of electronic circuits allows learning to be carried out in one place or in different places through distance learning. E-learning can be carried out anytime anywhere, but e-learning still has drawbacks, which requires users to deal with electronic equipment that is not flexible t...

This is an experimental study aimed to investigate 2-stage co-digestion of pretreated organic wastes mixed with fresh animal manure (BD) and digester’s operation conditions (digester temperature and pH) to enhance biomethane production. To increase lignocellulose digestibility and biomethane (BM) production, fruit + vegetable waste (FVW) and corn stalks + wheat straw (CR) in ratio (1:1), respectively, were pretreated with inoculum taken from an anaerobic digester of poultry manure at 35 °C. This AD experiment was performed in a fixed dome biodigester with volumetric capacity of 2.3 m 3 . Biomethane potential (BMP) tests were conducted for biomass treatments and inoculum used ( T 1 , T 2 , T i ) at 35 °C. In this study, the temperature of biodigester material was measured in mesophilic (30–40°C) and thermophilic (40–50°C) ranges and pH of fresh feed and slurry feed digesters was in optimum methane production range (7.01–7.52). The total daily methane productions from T 1 and T 2 were 125.13 ml/g VS and 104.89 ml/g VS in mesophilic range (30–40°C) while these values were 148.41 ml/g VS and 132.74 ml/g VS in mesophilic range (40–50°C), respectively. The 2nd stage digestion of slurry from fresh feed digester added 39–45% and 35–38% more methane production in T 1 and T 2 respectively. On calibration with BMP tests, experimental data have shown the synergetic effect on methane production and its thermal characteristics promoted by co-digestion of pretreated organic waste and BD. The economic and feasibility analysis proved the biomass co-digestion project viable and adoptable with positive (5.39 $) net return value (NRV), 2.92 years payback time (PBT), and 1.34 benefit cost ratio (BCR).

Dengan demikian mereka hanya menerima atau mengetahui data nilai tukar suatu Trading Forex yang sedang berlaku pada saat itu saja sehingga sulit untuk menganalisis atau memprediksi pergerakan nilai tukar masa yang akan datang. Pemain Forex biasanya menggunakan indikator untuk memudahkan mereka menganalisis dan memperdiksi nilai masa depan. Indikator merupakan alat bantu pengambilan keputusan. Trading forex adalah transaksi perdagangan mata uang suatu negara, dengan mata uang negara lainnya. Perdagangan berlangsung secara global antara pusat-pusat keuangan dunia dengan melibatkan bank-bank utama dunia sebagai pelaksana utama transaksi. Trading Forex menawarkan Jenis investasi yang menguntungkan dengan modal yang kecil dan tingkat keuntungan tinggi, dengan modal yang relatif kecil dapat memperoleh keuntungan berlipat. Hal ini disebabkan perdagangan forex terdapat sistem leverage dimana modal yang ditanam akan dilipat gandakan jika hasil prediksi buy/sell akurat, namun Trading Forex mempunyai tingkat risiko tinggi, akan tetapi dengan mengetahui saat yang tepat untuk bertransaksi (buy or sell) maka kerugian dapat dihindari. Trader yang melakukan investasi di pasar valuta asing dituntut untuk memiliki kemampuan menganalisis keadaan dan situasi dalam memprediksi selisih nilai tukar mata uang. Pergerakan harga forex yang membentuk pola (kurva) naik dan turun sangat membantu para trader dalam pengambilan keputusan. Pergerakan kurva dijadikan sebagai salah satu indikator dalam pengambilan keputusan untuk beli (buy) atau jual (sell). Penelitian ini membandingkan (Comparation) tipe kernel pada algoritma Support Vector Machine (SVM) untuk memprediksi pergerakan kurva pada live time trading forex menggunakan data GBPUSD, 1H. Hasil penelitian pada penelitian ini dari hasil dan pembahasan dapat di simpulkan bahwa Kernel Dot, Kernel Multiquaric, Kernel Neural tidak tepat digunakan untuk data non linier pada kasus data forex untuk mengikuti pola trend kurva, sebab kurva yang dihasilkan membentuk kurva linier (lurus) kemudian untuk tipe kernel yang kurvanya paling mendekati mirip dengan trend kurva trading forex online adalah kernel Anova dan Kernel radial, yang sedikit mendekati Kernel Gaussian Combination, kernel Epachnenikof dan untuk Kernel Polinomial membentuk kurva parabola terbuka.

In CHAPTER III (INTRODUCTION BOOKING) Article 7 Paragraph 1 states that the Treasurer keeps records of all the money administered. The purpose of this research is to design and produce an Android-based Financial Information System so as to assist the Receiving Treasurer in inputting transactions until the accountability report information is in accordance with the Director General of Treasury Regulation Number PER-47 / PB / 2014. Based on the results of the discussion and making of the Financial Information System at the Gorontalo-based Android University, it can be concluded that the system has been completed and can be used.

In early 2006, Gorontalo's unique handicraft products received attention from both central and provincial governments to fight for patents on products (Hinelo, 2008). It shows that the creative industry business run by the Gorntalo Society has been well developed. The researcher intends to design a mobile geographic information system based on android for mapping the location of craftsmen typical of Gorontalo handicraft. This system is the application of GIS mobile system that is integration between three technology, that is GIS software, Global Positioning System (GPS) technology, and mobile device. This mobile-based designed system is intended to make this system easier to use by the Community because the system can be accessed simply by using a mobile device.
