Penyelesaian Persamaan Poisson 2D dengan Menggunakan Metode Gauss-Seidel dan Conjugate Gradien

In this paper we focus on solution of 2D Poisson equation numerically. 2D Poisson equation is a partial differential equation of second order elliptical type. This equation is a particular form or non-homogeneous form of the Laplace equation. The solution of 2D Poisson equation is performed numerically using Gauss Seidel method and Conjugate Gradient method. The result is the value using Gauss Seidel method and Conjugate Gradient method is same. But, consider the iteration process, the convergence of the value is reached faster using Conjugate Gradient method

A review of Ghana’s food system and its implications on sustainability and the development of national food-based dietary guidelines

Food-Based Dietary Guidelines (FBDG) provide culturally-appropriate and actionable recommendations based on which populations can make healthy food choices. Food systems sustainability, from production to consumption, and disposal of food and foodrelated items, should be a critical consideration for developing such guidelines. This rapid review assesses Ghana's food systems to determine the level of sustainability to inform the FBDG recommendations. Peer-reviewed articles, documents and reports of relevance to Ghana were included in this rapid review. A hundred and eight papers, answering different questions on food system sustainability were reviewed. Bread, cereals, fish and indigenous vegetables are the most frequently consumed food groups. Sugar-Sweetened Beverages are the most consumed imported foods. In rural areas, 53% of dietary protein comes from plant sources. Fish is the main the source of animal protein for most Ghanaian households. There is intensive exploitation of marine and fresh water resources. Most livestock are raised by smallholder farmers using freerange system. Poultry is frequently kept on deep litter system and only a few are largescale. Crop production for household consumption and small-scale animal rearing are predominant, especially in Northern Ghana. By weight, fruits and vegetables are the least cultivated and consumed crops at the household level. Wood is the commonest source of fuel for cooking, especially in rural areas. Single use plastic is the most used and preferred material for food packaging. Indiscriminate and poor management of waste and pesticide misuse is commonly reported. The findings suggest the need for promoting production diversification, use of clean fuel and reusable food packaging as part of FBDGs to enhance sustainability of Ghana’s food systems.&nbsp

METODE LANGSUNG (DIRECT METHOD) TERHADAP PEMBELAJARAN MAKNA KATA PADA ANAK AUTIS

ABSTRACT The autistic students are the students who have social, behavioural, language, and communicatin disturbances. Those make autistic students difficult to live normally, especially on the aspects of language and communication which play an important role in the social interaction. Language learning for autistic students has special characteristics  empashizing on how produced words are suitable to the meaning which has been agreed by communities. Direct method is learning method which assumes that a good language learning is conducted through using the language intensively in the communication, so that the students use each language element that is appropriate to its meaning and intention. It is expected that the language that the autistic students produce words without meaning (ekolalia), but the meaningfull words. The purpose of this research is to describe the level of effectiveness using direct method on learning word meaning of the second year autistic students of Mutiara Hati special education elementary school Mojokerto. This quantitative research used Pre-Experimental Design with one Group Pre-Test and Post-Test. The subjects were 6 autistic students of second class in Mutiara Hati special education elementary school Mojokerto. The data were analyzed by using non parametric statistics with sign test. From the result of statistical test in this research showed that Zh score was 2.05, which means that Zh score = 2.05 is langer than critical value of 1.96, thus the Null hypothesis (Ho) was rejected and alternative hypothesis (Ha) was accepted. Therefore, it can be concluded that direct method is effective to use on learning word meaning of the second year autistic students of Mutiara Hati special education elementary school Mojokerto.   Keywords : Word Meaning Learning, Direct Metho

TINJAUAN ANALITIS TERHADAP MODEL PEMBANGUNAN INDONESIA

Development is generally defined as the fulfillment of individual welfare that includes per capita income, educational needs, health, quality of life including the need for self-esteem. In practice the planning and implementation of development is strongly influenced by the ideological perspective, political or development paradigm adopted by the elite in each country. Evolving paradigm begins with Classical Development Theory that was divided into various sects and schools of lower-schools of capitalism and socialism. Furthermore, also develops theories derivatives such as Dualistic Development Thesis, Structural Change Theory, Theory of Linear Stages/Stages of Economic Growth, International Dependency Theory, Counter-Revolution of Neoclassical Theory, and the latter Paradigm of Sustainable Development. Developing countries have doing many experiments with a mixture of the above theories ranging from a centralized to the schools of the liberal ideology which depends on the views adopted. The important thing to note, none of Developing Countries can solve the problem of development with only one theory unanimously adapt and intact. Because the theories of development is growing locally specific, so not entirely applicable to different situations. Since independence in 1945 Indonesia\u27s development itself can be said to have been changing schools. But there is one distinctive feature, namely applying a liberal theories but in a situation that is very centralized and very dominant role of government. However, due to the specific local situation and deepening less recognizable, always exposed to the dead-lock situation both in the Old Order and New Order

Pandangan tentang keselamatanahl al-kitab dalam tafsir al-maraghiThe Concept of Salvation for ahl al-kitab in the

ABSTRACT The main aim of the research is to review al-Maraghi\u27s interpretations of the all\u27 al-kitiib and its salvations. The model of research is library research. Then, the abundant data was collected from Tafsir al-Maraghi, especially his interpretations related to the topic. All of the data were collected by using Qur\u27anic concordance. The versus are collected by refering to words or phrases which indicates to the conditions, appreciations, and salvation of ahl al-kith\u27\u27\u27. Then they will be classified according to the content and al-Maraghi\u27s interpretations. The primary result of the research is that, according to al-Maraghi, basically all of the ahl al-kita communities will get salvation if they have "surrender to the will of God" or have islam (in its general meaning). However, in another side of his exegeses, he also emphasizes that the salvation for them must be restricted to believe in Muhammad. In other word, in order to get salvation they need to convert as Moslem first. Actually, this kind of doctrine, according to al-Maraghi, has been written down in its own sacred texts, but is corrupted by the writers or the scholars since the first time. Finally, it is worth nothing that most of al-Maraghi\u27s exegeses about the salvation of ahl al-kitiib are inclusive ones, This can be proved by the fact that most of his interpretations tend to appreciate their spirituality and belief.

Dengan memperhatikan aspek penyediaan bahan baku maka pendirian pabrik natrium nitrat di Kawasan Industri Cilegon, Jawa Barat. Bahan baku asam nitrat diperoleh dari PT Multi Nitrotama Kimia, Cikampek, sedangkan natrium klorida diperoleh dari PT Cheetham Garam Indonesia, Cilegon. Pendirian pabrik natrium nitrat direncanakan akan berdiri pada tahun 2017 dan pengoperaian pabrik pada tahun 2020. Reaksi pembuatan natrium nitrat (NaNO3) dilakukan dengan mereaksikan larutan asam nitrat ( HNO3) dengan larutan natrium klorida (NaCl) dalam Reaktor Alir Tangki Berpengaduk (RATB) yang dilengkapi dengan jaket pemanas pada tekanan 1,013 bar dan 60 0C. Pada perancangan ini digunakan rasio mol reaktan antara asam nitrat (HNO3) dengan natrium klorida (NaCl) yang digunakan adalah 1,5 : 1, sehingga akan diperoleh konversi sebesar 95% terhadap natrium klorida (NaCl) (U.S.Patent 221,5450,1940). Produk gas yang keluar dari reaktor masuk ke menara distilasi untuk dipisahkan antara chlorine (Cl2) dengan nitrosyl chloride (NOCl), sedangkan produk cair berupa sisa asam nitrat ( HNO3) dan natrium klorida (NaCl), produk berupa natrium nitrat (NaNO3) dan air (H2O) yang terbentuk di reaktor dialirkan ke evaporator untuk penguapan air dan sebagian asam nitrat. Larutan dari evaporator dikristalkan dalam crystallizer. Dari crystallizer, produk diumpankan ke centrifuge untuk memisahkan kristal dengan mother liquor-nya, dan selanjutnya kristal dikeringkan di dalam rotary dryer. Unit pendukung proses didirikan untuk menunjang proses produksi yang terdiri dari unit penyediaan air 3.239,5882 kg/jam, steam 8.353,9849 kg/jam, tenaga listrik disuplai dari PLN 500 KW dan listrik cadangan dari generator 400 KW, penyediaan bahan bakar menggunakan natural gas untuk bahan bakar boiler 402,7303 L/jam dan diesel oil untuk generator 0,08 L/jam, serta unit pengolahan limbah. Agar mutu bahan baku dan kualitas produk tetap terkendali, maka keberadaan laboratorium sangat diperlukan. Dalam pabrik Natrium Nitrat ini terdapat tiga buah laboratorium, yaitu laboratorium fisik, laboratorium analitik, dan laboratorium penelitian dan pengembangan. Bentuk perusahaan adalah PT (Perseroan Terbatas) dengan struktur organisasi line and staff. Sistem kerja karyawan berdasarkan pembagian jam kerja yang terdiri dari karyawan shift dan non shift. Hasil analisa ekonomi terhadap prarancangan pabrik natrium nitrat diperoleh bahwa Total Cost Investment (TCI) US$11.850.014dan total biaya produksi (Production Cost) US$ 1.832.993. Dari analisa kelayakan diperoleh Return of Investment (ROI) sebelum pajak 50,50% dan setelah pajak 35,35%. Pay Out Time (POT) sebelum pajak 1,71 tahun dan setelah pajak 2,31 tahun, Break Event Point (BEP) 43,29%, Shut Down Point (SDP) 31,94% dan Discounted Cash Flow (DCF) 24,70%. Dari analisis ekonomi yang telah dilakukan, dapat diambil kesimpulan bahwa pendirian pabrik natrium nitrat dengan kapasitas 55.000 ton/tahun layak dipertimbangkan untuk direalisasikan pembangunannya
