This research develops a model of characteristic training and character education management to produce academic, profession, and vocational (potential teacher and teacher) teachers who have superior competence in disseminating noble character of the nation. By using Researh & Development approach, this research uses Padepokan Character locus PPKn FIS Unnes Department. The subjects of the study were the newly graduated Unnes students, the young teachers in Semarang City and Central Java Province. The factual model of training management and the development of character education that runs so far contains weaknesses in various aspects, from planning, implementation, to evaluation of activities. On the basis of the analysis of a number of weaknesses of the factual model is then carried out the reconstruction of the conceptual model departs from the review of ethical factors and emotic factors. Conceptual model is then refined again by accommodating the results of focus group discussion with the stake holders and utilize the potential and resources owned by the character padepokan Unnes Political Education and Citizenship. This model has incorporated various aspects of the training, from the refinement of the factual model greed, the consideration of ethical factors and the emotional factors, as well as the aspirations and needs of the stake holders, so it is feasible to experiment in the wider domain.
Abstrak. Biogas merupakan salah satu energi alternatif yang sekarang banyak dikembangkan. Selain murah, biogas juga ramah lingkungan. Metan (CH4) merupakan unsur gas yang menentukan kualitas biogas. Bila biogas memiliki kadar metan yang tinggi maka biogas tersebut akan memiliki nilai kalor yang tinggi. Oleh kerana itu kemurnian biogas tersebut penting. Sehingga perlu melakukan penelitian pemurnian biogas yang bertujuan untuk meningkatkan kadar gas metan (CH4) dengan rancangan alat pemurni dan untuk meningkatkan nilai guna biogas. Metode yang dilakukan adalah adsorpsi menggunakan kombinasi arang aktif dan zeolit alam dengan perbandingan, 30 : 70 m/m, 50 : 50 m/m dan 70 : 30 m/m dengan waktu pemurnian selama 30, 60 dan 90 menit. Hasil penelitian diperoleh alat purifier biogas yang terbuat dari pipa paralon yang dilapisi fiber dengan dimensi panjang 60 cm dan diameter 10 cm. Semakin lama waktu pemurnian maka konsentrasi gas metan yang dihasilkan akan semakin tinggi yaitu pada lama pemurnian 90 menit. Kombinasi arang aktif dan zeolit dengan perbandingan 50 : 50 m/m merupakan kombinasi terbaik dalam melakukan pemurnian biogas.
ABSTRAK Guludan horizontal (searah kontur) telah terbukti sangat efektif menurunkan laju erosi tanah pada lahan kentang, namun efektifitasnya dalam meningkatkan kualitas tanah maupun produktivitas tanaman yang optimal perlu dikaji lebih mendalam. Penelitian ini bertujuan untuk mengidentifikasi pengaruh kombinasi mulsa dan pupuk terhadap erosi dan kehilangan nutrisi tanah pada lahan kentang dengan aplikasi bio-arang dan guludan horizontal. Sebanyak 6 demplot kentang (6 m x 3 m) dengan aplikasi bio-arang (5 ton/ha) dan guludan horizontal (5 lajur) disiapkan masing-masing untuk perlakuan mulsa plastik-pupuk organik (MPO), mulsa jeramipupuk organik (MJO), tanpa mulsa-pupuk organik (TMO/kontrol), mulsa plastikpupuk anorganik (MPK), mulsa jerami-pupuk anorganik (MJK), dan tanpa mulsapupuk anorganik (TMK/kontrol). Laju aliran permukaan (runoff) dan kehilangan tanah (soil loss) pada setiap demplot diukur pada setiap kejadian hujan dengan menggunakan kolektor sedimen, serta kadar N-total dan P-total-nya dianalisis di laboratorium masing-masing dengan menggunakan metode Kjeldahl dan Kolorimetri. Hasil penelitian menunjukkan bahwa MPK mampu menahan laju runoff dan soil loss lebih baik daripada yang lain atau masing-masing 11.9-18.1% dan 41.8-48.1% lebih efektif dibanding kontrol. Lebih jauh, MPK dapat menekan kehilangan N-total dan P-total lebih signifikan daripada yang lain atau masing-masing 30.1-38.9% dan 31.9-44.8% lebih baik dibanding kontrol. Dengan demikian, MPK dipandang sebagai kombinasi yang sesuai untuk budidaya kentang dengan aplikasi bio-arang dan guludan horizontal. KATA KUNCI Budidaya kentang; erosi tanah, guludan horizontal; kehilangan nutrisi tanah; kombinasi mulsapupuk
ABSTRAKKeterangan umur simpan (masa kadaluarsa) produk pangan merupakan salah satu informasi yang wajib dicantumkan oleh produsen pada label kemasan produk pangan. Penentuan umur simpan produk pangan dapat dilakukan dengan menyimpan produk pada kondisi penyimpanan yang sebenarnya. Cara ini menghasilkan hasil yang paling tepat, namun memerlukan waktu yang lama dan biaya yang besar. Metode pendugaan umur simpan dapat dilakukan dengan metode Accelerated Shelf-life Testing (ASLT), yaitu dengan cara menyimpan produk pangan pada lingkungan yang menyebabkannya cepat rusak, baik pada kondisi suhu atau kelembaban ruang penyimpanan yang lebih tinggi. Tujuan dari penelitian ini adalah (1) untuk menduga umur simpan gula kelapa kristal dengan dua jenis bahan kemasan yang berbeda dan menggunakan metode ASLT (Accelerated Shelf Life Testing) (2) untuk memberikan jaminan mutu mengenai keamanan gula merah. Variabel yang diamati pada penelitian ini meliputi : kadar air awal produk (Mo, g H 2 O/g padatan), kadar air kesetimbangan produk (Me, g H 2 O/g padatan), kemiringan/slope kurva sorpsi isotermis (b), kadar air kritis (Mc, g H 2 O/g padatan), konstanta permeabilitas uap air kemasan (k/x, g/m 2 .hari.mmHg), luas permukaan kemasan (A, m 2 ), berat kering produk dalam kemasan (Ws, g padatan), tekanan uap air jenuh (Po,mmHg). Hasil penelitian menunjukkan bahwa umur simpan gula kelapa kirstal yang dikemas menggunakan alumnium foil yang disimpan pada RH 60% adalah 11 bulan, sedangkan yang dikemas dengan Plastik PE adalah 18 bulan. ABSTRACT Information on shelf -life (expiration period) of food products is one of the information that must be included by producers on food product packaging labels. Determining the shelf life of food products can be done by storing the product in actual storage conditions. This method produces the most appropriate results, but requires a long time and a large cost. Estimating method of shelf life can be done using the AcceleratedShelf-life Testing (ASLT) method, which is by storing food products in an environment that causes them to break down quickly, both at higher temperature or humidity conditions. The purpose of this study are (1) to estimate the shelf life of crystal coconut sugar with two different types of packaging materials and use the Accelerated Shelf Life Testing method (ASLT) ,(2) to provide quality assurance regarding the safety of brown sugar. The variables observed in this study are: the initial moisture content of the product (Mo, g H2O/g solids), the product equilibrium moisture content (Me, g H2O/g solids), slope/slope of the isothermic sorption curve (b), critical water content (Mc, g H2O/g solids), vapor permeability constant of bottled wate (k/x, g/m2.day.mmHg), area packaging surface (A, m2), dry weight of packaged products (Ws, g solids), saturated water vapor pressure (Po,mmHg). The results showed crystal coconut sugar using aluminum foil
Social studies have an essential role in applying character values for students. The purpose of social studies is to form good character and prepare students to become good citizens. This is following the goals of character education for children with special needs, namely to meet needs, familiarize social life, and form good behavior and attitudes following the norms prevailing in the society. Therefore, students must live in harmony with the community, and so must be applied in students. So that the problems in the form of a lack of independent nature and self-confidence of SLB students at YPAC Semarang are problems that must be resolved by teachers and schools as facilitators, a low character of student discipline accompanies this lack of attitude, so schools need to implement it. For SMPLB D / D1 YPAC Semarang, character internalization that is trying to be carried out includes the value of the self-confident character to find their potential and develop according to their talents. Have an independent nature to equipping children with special needs to live independently by minimizing assistance from other parties and the character of discipline that will later become provisions before living in society.
