IndonesianKesenjangan tingkat produktivitas padi di Indonesia cukup besar yang di antaranya dipengaruhi oleh luasnya wilayah pertanaman. Hal ini berdampak pada desain dan penerapan model Asuransi Usaha Tani Padi (AUTP) berbasis produktivitas. Perluasan klaster pada tingkat provinsi diperkirakan dapat mengurangi keragaman produktivitas di tingkat wilayah kota/kabupaten sebagai risiko dasar pemanfaatan skema AUTP berbasis klaster. Klaster, sebagai wilayah atau zona, diperlukan untuk menentukan indeks kritis produktivitas yang akurat dalam rangka penghitungan tingkat premi yang tepat. Kajian ini bertujuan untuk menentukan tingkat produktivitas kritis pada lahan padi yang menerapkan skema AUTP. Kajian ini menggunakan analisis statistik dengan pendekatan batas bawah Two Sigma yang dapat dianggap sebagai batas produktivitas kritis untuk setiap klaster. Teknik ini memberikan persentase yang rendah atas klaim yang terjadi, serta ekspektasi dan simpangan baku dari risiko dasar kerugian. Tarif premi murni yang diperoleh adalah Rp85.191,18, hampir 2,5 kali lipat lebih kecil dibandingkan dengan menggunakan teknik lain sebagai batas poduktivitas. Hasil kajian ini mengungkapkan bahwa penggunaan skema berbasis klaster lebih baik dari skema berbasis provinsi, sebagaimana ditunjukkan oleh nilai TVaR. Kajian ini menyarankan agar Kementerian Pertanian dapat merancang model AUTP berbasis produktivitas berdasarkan klaster dengan setiap klaster memiliki nilai indeks produktivitas kritis yang berbeda untuk menetapkan tingkat premi yang dikenakan.EnglishThere is a large gap in productivity of paddy in Indonesia which is, among others affected by the area size of crop planting. This condition should influence the design and application model of the rice crop insurance scheme. Developing clusters under the province level is recommended to reduce the heterogeneous productivity as basis risk within regencies/municipalities in improving the area yield index of crop insurance policy in Indonesia. Clusters, as the zone, are necessary to determine accurate critical yield index leading to a more precise premium rate making. This study aims to determine critical productivity level on rice crop insurance area. This study applied statistical analysis using the lower bound of Two Sigma as a critical yield for each cluster. This technique provides a small percentage of claim, and the expectation and standard deviation of basis risk loss. The pure premium rate obtained from the analysis is IDR85,191.18, that is almost 2.5 times less than using other methods as trigger productivity. The analysis result emphasized that the use of the cluster-based scheme is better than the province-based as shown by TVaR value. The study suggests that the Ministry of Agriculture could design the area yield index based on clusters as each cluster will have a different critical productivity index with adjusted premium rate value.

Bats have the second largest diversity in mammalian classes after rodentia (Nurfitrianto et al., 2013). Bat population reaches approximately 1100 species (Teeling et.al 2005). In Indonesia there are 205 or 21% of known world bat species (Suyanto 2001). Bats are the only flying mammals. The ability bat to fly is supported by the shape of the extremities and also the adaptation of the cardiovascular organs. Based on empirical studies of cardiovascular was known that cardiac muscle mass is a good indicator for the degree of adaptive specialization of prolonged locomotor activity, in both birds and mammals. Data on cardiovascular muscle morphology and muscles that support flying ability will provide an overview of the behavior, ecology and physiology of certain animals (Bishop 1997).Several studies have been conducted to study the cardiovascular system of bats. Research on bat hematology profile has been done (Heard and Whittier 1997, Mclaughlin et.al 2007, Wawrocka and Bartonicka 2014, McMichael et al. 2015, Ratnasooriya 2016, Rashid et al, 2016, Rahma et al., 2018). Joseph (1908) says that every animal has a different size and heart shape to each other. This heart size difference is influenced by the size of the body and the high energy required by the animal (Joseph 1908).Bat's heart rate is known to increase during flight (Thomas and Suthers 1972). This is causes an increase in the rate of metabolism. Writing this paper will discuss about the uniqueness of the bat's heart so that it can support its ability to fly.

Fruit bats have been reported as the natural reservoir of many emerging and re-emerging zoonotic diseases. Infected bats usually do not show any clinical symptoms and are infected persistently. This unique characters indicate that bats have high immune activity to combat viruses even in its physiological state. High immune activity will affect the size of lymphoid organ and produce high level of reactive oxygen species (ROS). Spleen is one of the important lymphoid organ which have a strategic function in elimination of blood borne pathogens. This study was undertaken to provide information on the normal size of spleen and to analyze malonaldehyde (MDA) and super oxide dismutase (SOD) levels of free range fruit bats (Cynopterus brachyotis). The ratio of body weight/spleen was 0.4% and there were no significance differences between the male and female bats. The spleen MDA levels which represent ROS generation was higher than those of the liver. Male bats with higher levels of MDA tend to have bigger spleen size than the female which has lower MDA levels. High levels of MDA might indicate a high immune activity inside the spleen. Despite the negative effect of ROS to genetic material, high level of ROS can be advantageous to support the bats immune system as a viral reservoir. High levels of MDA are generally accompanied by high levels of SOD which might reduce the negative impact of oxidative stress in the C. brachyotis.

Hematology value is important to evaluate individual health status. This study was purposed to observe the hematological values of male and female Cynopterus titthaecheilus. The study was conducted on 16 C. titthaecheilus (six adult males, six adult females and four juveniles) to study the haematological profiles. Blood samples were taken using tuberculin needles and analyzed by hematology analyzer for hematological values. Females C. titthaecheilus had a higher number of white blood cells than the males, but no differences in the white blood cells differential. Males C. titthaecheilus had a higher number of platelets than the females. Generally, the juveniles had a higher number of leucocytes as well as number of platelets than the adults. Based on the stress index value, it was concluded that young bats had a lower stress level compared to adult bats.

Various efforts have been carried out by the Indonesian Government to increase rice production, especially the construction of new paddy fields and paddy intensification through increasing intensity or planting frequency in a year. Overcoming the problems of chemical and physical soil properties that have caused low soil productivity is an effort that can be made to increase rice production. This study was aimed to assess the quality of soil physical and chemical properties of the paddy fields in order to find out the cause of the low productivity of paddy soils. The study was conducted in 24 locations in Banten and West Java Provinces. In general, based on their soil quality indexes, the study found that the soil physical quality of paddy soil is good and better than soil chemical quality. There was no significantly different between soil physical quality of paddy soil in Banten and West Java Provinces. However, the soil chemical quality of paddy soils in West Java Province is significantly better than in Banten Province. There were no limiting factors for soil physical properties, while in some locations, some limiting factors of soil chemicals properties were found. Dominant limiting factors for plant growth were the low available P, organic matter and total organic N contents, low pH, and low exchangeable K, and high level of Fe.

A non-invasive blood glucose monitoring device is performed without injuring the limbs. One method of measurement in the form of qualitative and relatively simple to use because the process is fast and requires a cheap cost, namely Fourier Transform Infrared (FTIR). Spectroscopic results allow for a shifting of the scatter, since the same object is measured several times incorrectly producing the same spectrum, requiring a preprocessing method to reduce the problem. However, in some cases it is difficult to identify the existing data pattern, so that a nonparametric approach is needed to identify the pattern of data held so that in the process of calibration model obtained accurate results. Smoothing Spline is one nonparametric method is piecewise polynomial, which is a piece of polynomial that has a segmented property on the hose k that formed at knot points, thus providing flexibility in constructing the shape of the curve that we have. The Smoothing Spline method produces an optimum value when the GCV value is minimum on the use of a linear order with sixteen knot points. The resulting varians value after Smoothing Spline method is smaller than before smoothing, this indicates that this method can minimize the effect of liquefaction in the non-invasive blood glucose value spectrum. In addition, Smoothing Spline method can also capture data patterns well.

The evaluation step in school accreditation process includes eight components of national education standard (SNP). The result of accreditation from the evaluation is believed to explicate the academic achievement of student, in this case is National Examination (UN). Thus, it is necessary to further observe the relation between the accreditation results and the score of national examination. One of the analysis that can be used is regression analysis, it is used to observe the relation between the accreditation result and the sroce of national examination also to identify the SNP components that affect the national examination score. However, since the study was conducted at senior high school level where the national examination score for this level covers six subjects, the analysis used is no longer a simple regression but a multiple variable regression. It is because of the relationship between the score of the national examination that characterizes an academic achievement. The application result of multiple variable regression method shows that there is a relation between SNP and national examination score.

Transfer function model with multiple input is a multivariate time series forecasting model that combines several characteristics of ARIMA models by utilizing some regression analysis properties. This model is used to determine the effect of output series towards input series so that the model can be used to analyze the factors that affect the Jakarta Islamic Index (JII). The USD exchange rate against rupiah and Dow Jones Index (DJI) were used as input series. The transfer function model was constructed through several stages: model identification stage, estimation of transfer function model, and model diagnostic test. Based on the transfer function model, the JII was influenced by JII at the period of one and two days before. JII was also affected by the USD exchange rate against rupiah at the same period and at one and two days before. In addition, the JII was influenced by DJI at the same period and also at period of one until five days ago. The Mean Absolute Prencentage Error (MAPE) value of forecasting result was 0.70% and the correlation between actual and forecast data was 0.77. This shows that the model was well performed for forecasting JII.
