Fermentation Quality and in Vitro Nutrient Digestibility of Fresh Rice Straw-Based Silage Treated with Lactic Acid Bacteria

The aim of the experiment was to evaluate fermentation characteristics and in vitro nutrient digestibility of fresh rice straw-based silage ensiled with addition of epiphytic lactic acid bacteria (LAB) inoculant. The experiment was arranged in a completely randomized design, with 2 × 2 factorial arrangement of treatments. The first factor was the ratio of fresh rice straw (FRS), tofu waste (TW) and cassava waste (CW) consisted of two levels i.e., 40 : 20 : 40 and 40 : 25 : 35, on dry matter (DM) basis). The second factor was the level of LAB inoculant with two levels ie., 0 and 20 mL/kg FM. The treatments were (A) FRS + TW + CW with the ratio of 40 : 20 : 40, without LAB inoculant; (B) FRS + TW + CW with the ratio of 40 : 20 : 40 + LAB inoculant; (C) FRS + TW + CW with the ratio of 40 : 25 : 35, without LAB inoculant; (D) FRS + TW + CW with ratio of 40 : 25 : 35 + LAB inoculant. Results showed that addition of LAB inoculant in silage increased lactic acid concentration (P0.05) on chemical composition, fermentation quality of silage and in vitro digestibility. It was concluded that mixture silage with ratio of 40 : 20 : 40 with the addition of LAB inoculant had the best fermentation quality and nutrient digestibility than other silages

Exploration of the MSSM with Non-Universal Higgs Masses

We explore the parameter space of the minimal supersymmetric extension of the Standard Model (MSSM), allowing the soft supersymmetry-breaking masses of the Higgs multiplets, m_{1,2}, to be non-universal (NUHM). Compared with the constrained MSSM (CMSSM) in which m_{1,2} are required to be equal to the soft supersymmetry-breaking masses m_0 of the squark and slepton masses, the Higgs mixing parameter mu and the pseudoscalar Higgs mass m_A, which are calculated in the CMSSM, are free in the NUHM model. We incorporate accelerator and dark matter constraints in determining allowed regions of the (mu, m_A), (mu, M_2) and (m_{1/2}, m_0) planes for selected choices of the other NUHM parameters. In the examples studied, we find that the LSP mass cannot be reduced far below its limit in the CMSSM, whereas m_A may be as small as allowed by LEP for large tan \beta. We present in Appendices details of the calculations of neutralino-slepton, chargino-slepton and neutralino-sneutrino coannihilation needed in our exploration of the NUHM.Comment: 92 pages LaTeX, 32 eps figures, final version, some changes to figures pertaining to the b to s gamma constrain

Aplikasi Model GARCH pada Data Inflasi Bahan Makanan Indonesia

In the econometric analysis of time series, data with high volatility will bevery risky to be used as a basis for doing forecasting. Included in this analysis is thevolatility of food inflation in Indonesia. Time series data have a tendency to bully theerror variance (error term) are constant over time. Appropriate econometric model toestimate such behavior is called the Autoregressive Conditional Heteroscedasticity (ARCH)model (Engle, 1982) and the Generalized Autoregressive Conditional Heteroscedasticity(GARCH) model developed by Borreslev 1986. This paper attempts to use models ofARCH / GARCH to explain the behavior of food inflation in Indonesia period 2005.1-2010.6, explained by incorporating elements of ARCH / GARCH this will produce abetter estimation

Anti-terrorism Legal Framework in Indonesia: Its Development and Challenges

Indonesia is a nation that has been subject to many of high profile terrorist cases. In relation to this, Indonesia's legal framework on anti-terrorism contains provisions that have been generally practiced by other countries. After the 2002 Bali Bombing, the Indonesian government issued Government Regulation in Lieu of Law (Perpu) No. 1/2002 on Anti-terrorism and Perpu No. 2/2002 (which made the Perpu No.1/2002 retroactively applicable to the Bali bombings). The parliament adopted both in early 2003 in the form of Law No. 15/2003 and Law No. 16/2003. The Constitutional Court decided that Law No. 16/2003 was in-constitutional, because it was against principle of non-retroactivity stipulated under Article 28I of the 1945 Constitution. Indonesia adalah korban dari beberapa serangan teroris bersakal besar. Terkait terorisme ini, kerangka hukum anti-terorisme telah memuat ketentuan-ketentuan yang secara umum juga diterima oleh berbagai negara. Pasca Bom Bali tahun 2002, lahirlah Peraturan Pengganti Undang-Undang (Perpu) No. 1/2002 tentang Pemberantasan Tindak Pidana Terorisme dan Perpu No. 2/2002 yang memberlakukan surut Perpu 1/2002 untuk peristiwa Bom Bali. Dua Perpu itu kemudian diterima menjadi Undang-Undang (UU) oleh Dewan Perwakilan Rakyat (DPR) dalam bentuk UU No. 15/2003 dan UU 15/2003. Mahkamah Konstitusi memutuskan bahwa ketentuan pemberlakuan surut itu bertentangan dengan asas non-retroaktif yang tercantum dalam Undang-Undang Dasar 1945 khususnya Pasal 28I

Application of Copper Fungicide and Row Covers to Control Phytophthora Seedling Blight Disease on Cocoa

Phytophthora seedling blight disease is one of the important diseases in cocoa. The disease is caused by the fungus of Phytophthora palmivora belongs to class Oomycetes. The aim of this research was to determine the effectiveness of the use of row covers and copper oxide fungicide applications to control seedling blight Phytophthora. Covering treatment was to place cocoa seedlings inside bamboo frame covered by transparent plastic in order to avoid from rainfall effect. The research was conducted in the Kaliwining Experimental Station at Indonesian Coffee and Cocoa Research Institute (ICCRI). Experiments were carried out four treatments and repeated 6 times. Each treatment consists of 100 seedlings planted in polybags and placed in the nursery area with a protective paranet. The treatment consisted of (1) row covers, (2) spraying of copper oxide 0.2%, (3) a combination of row covers and copper oxide 0.2% and (4) control (no covers and spray). Observations made 7 days after treatment with an interval of 7 days for 10 weeks. The results showed that row covers able to prolong the incubation period of the disease for 14 days, while the application of row covers + copper oxide 0.2% was able to save cocoa seedlings by 96.2%

Correlation between direct dark matter detection and Br(B_s -> mu mu) with a large phase of B_s - anti-B_s mixing

We combine the analyses for flavor changing neutral current processes and dark matter solutions in minimal-type supersymmetric grand unified theory (GUT) models, SO(10) and SU(5), with a large B_s - anti-B_s mixing phase and large tan beta. For large tan beta, the double penguin diagram dominates the SUSY contribution to the B_s - anti-B_s mixing amplitude. Also, the Br(B_s -> mu mu) constraint becomes important as it grows as tan^6 beta, although it can still be suppressed by large pseudoscalar Higgs mass m_A. We investigate the correlation between B_s -> mu mu and the dark matter direct detection cross-section through their dependence on m_A. In the minimal-type of SU(5) with type I seesaw, the large mixing in neutrino Dirac couplings results in large lepton flavor violating decay process tau to mu gamma, which in turn sets upper bound on m_A. In the SO(10) case, the large mixing can be chosen to be in the Majorana couplings instead, and the constraint from Br(tau -> mu gamma) can be avoided. The heavy Higgs funnel region turns out to be an interesting possibility in both cases and the direct dark matter detection should be possible in the near future in these scenarios.Comment: 19 pages, 8 figure
