Morphological characterization of Madura cattle in Madura islands was done as an input for "action plans" of national animals genetic resources management according to the global system ofFAO. Assessments were done in Sumenep District and Pamekasan District, East Java. According to the body measurements, Madura cattle can be classified as a small to medium type with withers height of about 120 cm. Because of potential productivity in the limitation of environmental resources, Madura cattle can be classified as a "superior" cattle . Body measurements of Madura cattle in the present study were relatively the same with those of 50 years ago, indicating that there is no breeding improvement activities except natural selection . The variability of body measurements is relatively narrow . Improving productivity by outbreeding is needed . To conserve the unique germ plasm of the Indonesian genotype, such as Madura cattle and a possibility to improve their productivity by a complete prevention of cross breeding in the Madura islands needs further evaluation . Â Keywords: Madura cattle, morphological characteristic, conservation

A complete block design was applied to employ 40 weaner goats, initial weighing average of 14.6 kg, which were grouped into 5 supplementary treatments, i.e. 125, 250, 300, 350 dan 400 g of skim milk/d. Each animal received.1.25 kg gliricidia leaves. Mixed pasture was consumed freely. The research was conducted in Tanjungrejo village, Tongas district, Probolinggo. A digestibility study was conducted for 7 days. Measurements included nutrient intakes and digestibilities, liveweight gain, and feed conversion ratio. Data were analyzed using the GLM procedure of SAS (SAS, 1986). The results showed that the medium skim milk level (300 g/d) gave the highest dry component digestibility. Cell wall digestibility from the group given 125-300 g skim milk/d was higher (P<0.05) than those given 350-400 g/d. No significant (P>0.05) difference in organic matter or protein digestibility was found among treatments. Supplementation with 350 g skim milk/d gave higher protein or digestible protein consumption (P<0.05), while supplementation with 125 g/d gave the best feed utilization efficiency. Levels at 125-250 g skim milk/d gave weight gain of about 65 g/d, while at more than 250 g gave 57 g/d or less. The best feed conversion ratio (7.8) was obtained in the group fed 125 g skim milk/d. In order to optimize microbial activity in the rumen, provision of slowly rumen degradable protein sources such as legumes, or rumen undegradable protein is of great importance.

Improving sheep productivity can be conducted by genetic improvement and improving environmental factors. Genetic improvement usually can be done by selection and creating composite or synthetic breed by crossbreeding. Composite breed created by crossbreeding between different breeds and followed by selection. The study of crossing between Sumatra sheep with fat-tail sheep from East Java, St . Croix hair sheep (US) and Barbados Blackbelly hair sheep has been carried out since 1986, and show that the crossbred are better in term of production and reproduction . In 1996/1997, the first generation (F1) of composite breed (KOM) has been created by crossing between Barbados Cross (BC) rams and St . Croix Cross (HC) ewes or reciprocally. The second generation (F2) of composite breed has been created by inter-se mating . However, F1-KOM and F2-KOM Â vary in their performances, therefore selection should be conducted. The results showed that birth weight and weaning weight of crossing between BC rams and HC ewes tended to be heavier than those of reciprocal crossing between HC rams and BC ewes, but the differences were not significant (P>0 .05) . Birth weight and weaning weight of crossing between BC rams with HC ewes and reciprocal cross were 2.48 _+ 0.70 kg (n=791), 12 .50 _+ 3 .26 kg (n=640) and 2.37 _+ 0.62 kg (n=147), 12 .29 _+ 3.30kg (n=122), respectively . Meanwhile, observations of inter-se mating of Fl-KOM showed that the weight at the first mating was 26 .7 _+ 3.82 kg (n=80), age of dam at the first lambing was 15 .7 _+ 1 .73 months (n=83), weight at post-partum was 29 .86 _+ 3 .30 kg, and litter size at the first parity was 1 .43 _+ 0.59 (n=83) . The mean of age at the first mating of KOM was around 10 .7 months. Mean of mating weight at the second parity was 28 .29 +_ 3 .51 kg (n=11), age of dam at the Â second lambing was 20.6 _+ 1 .99 month (n=11), post-partum weight was 26 .92 _+ 4.03 kg (n=11) and litter size was 1 .64 _+ 0.81 (n=11) .

Publisher : Indonesian Animal Sciences Society

Two years field study has been carried out in the Purwakarta district , West Java, to evaluate sheep productivity of Sumateran Composite (K) and Barbados cross (BC) breeds introduced to the farmers, compared with locally thin tail sheep breed (L) that were maintained by the farmers. Genotype compositions of K sheep were Barbados Blackbelly 25%, St. Croix 25%, and Sumateran sheep 50%; and for BC were Barbados Blackbelly 50% and Sumateran sheep 50%. Sheep those were introduced was new breed from breeding improvement of Indonesian Research Institute for Animal Production. Litter size of K, BC, and L ewes was 1.3; 1.4; and 1.5 respectively. Pre-weaning mortality rate were 5.0; 5.0 and 8.0% respectively for K, BC, and L lambs. Ewe Reproduction Rate (LRI = number of lamb at weaning/ewe/year) of L (2.14) was higher than BC (2.0) and K (1.85). The ewe productivity (PI = kg lambs/ewe/year) is the average of weaning weight timed LRI. Because the weaning weight of L (7.0 kg) were significantly lowest than BC (10.5 kg) and K (9.25 kg) will affect on PI. PI of L (14.98) ewe were significantly (P<00.5) lowest than BC (21) and K (17.11). Body weight of crossbred (K X L and BCxL) under the same physiologic status were similarly with BC and K. According to the result of productivity evaluation of introduced sheep breed in the field condition, can be sumarize that productivity of K and BC sheep were significantly better than locally thin tail sheep.

Under semi-intensive conditions, the composite genotype (K) (25% Barbados Blackbelly; BB, 25% St. Croix; SC, 50% Sumatra Thin Tail; DETS) showed relatively have similar weaning weight as compared to other contemporary crossbred, therefore under intensive conditions (confined), they are expected to have better performances. The objective of the study are to find performances of the second generation composite genotype lambs and the first generation performances of the ewes, as well as several genetics parameters under intensive conditions, and compared to the Barbados Blackbelly Cross (BC) as contemporary crossbred. The growth of pre- and post-weaning of BB crossbred (BC) and the second generation of composite genotype (K-F2) are relatively the same. Growth curve using Von Bertalanffy model with the equation of Wt (t) = A*(1-B*e**(- K*t)), show that the equation for BC is Wt (t) = 26.8(1-0.92e**(-0.01t) and for K-F2 is Wt(t) = 26.1(1-0.92e**(-0.01t). This equation indicate that the growth of BC and K-F2 is not significantly different. The BC and K-F2 genotype reach maturity at the weight of 26.8 and 26.1 kg, respectively, and both with rate of reaching maturity of 0.01. Mating weight and weight at lambing of those two genotypes are around 29 - 30 kg dan 31 kg, respectively. The mean of litter size of BC and K-F1 are 1.52 and 1.48, respectively or around 1.5. The average litter size at weaning are 1.39 and 1.34, respectively for BC and K-F1. This means that pre-weaning mortality are around 5.37 and 9.76%, respectively for BC and K-F1. The lambing interval of BC and K-F1 are 211 and 223 days, or 0.58 and 0.61 year, respectively. Therefore the reproductive rate (RR) of the respective genotype are 1.39/0.58 = 2.39 and 1.34/0.61 = 2.19, respectively. The average of litter weight at weaning (LWW) of BC x BC, SC crossbred (HC) x BC and K-F1 x K-F1 are 11.62, 12.60 and 11.83 kg, respectively. Therefore based on the ewe genotype the LWW of BC and K-F1 are 11.74 and 11.83 kg, respectively. Flock productivity (FP) for those two genotypes per year are 20.24 and 19.39 kg, respectively for BC and K-F1. Dam productivity index (DPI) that calculated as /ewe weight for those two genotypes are 0.67 and 0.66, respectively for BC and K-F1. Meanwhile, the flock efficiency index (FEI) that calculated as FEI = FP/ewe weight0.75 for the respective genotypes are 1.57 and 1.54 for BC and K-F1. The estimates of repeatability of litter weight at weaning show relatively low value (0,092), therefore the estimate of MPPA (Most Probable Producing Ability) for predicting the future productivity is relatively the same. The estimate of MPPA for litter weight at weaning (LWW) for the respective genotype are 11.79 and 11.81 kg, respectively for BC and K-F1. Results of the study show that performances of composite genotypes (F) and the contemporary crossbred (BC) are relatively similar in the traits of growth, dam productivity and the estimate of MPPA.

According to the Presidential Decree, central and local governments must implement electronic-based government systems or sistem pemerintahan berbasis elektronik (SPBE). However, the independent implementations have created various similar applications to support the same field of governmental activities. The situation creates difficulties in achieving effectiveness, integration, sustainability, efficiency, accountability, interoperability, and security of governmental services. Therefore, a common application will be developed for each governmental activity to improve interoperability and data integration. On the other hand, central or local governments must consider the suitable implementation of their public service information systems. This manuscript guides the determination of alternatives using cost, benefit, and risk analysis. We use the proposed guidance for a case study because sistem pengelolaan pengaduan pelayanan publik nasional-layanan aspirasi dan pengaduan online rakyat (SP4N-LAPOR!) has been regulated as the common application for Public Service Complaints Management using PermenPANRB No. 680, 2020. The application of the proposed guidance shows that it can help the stakeholder quantitatively decide on an alternative implementation of the application for the public service complaints management system.

Characterization of Various Kinds, Thickness and Bentonite Sand Ratio as Hardplain Materials: a Basic Concept for Coastal Sandy Land Management (Saparso, Tohari, D. Shiddieq, and B. Setiadi): Coastal sandy land developmentÂ facesÂ the sand characteristics, the lower holding water capacity and the larger nutrient leaching due to heavier rainfall in the tropics, soil porosityÂ and without soil layering so it need alternative technologyÂ forÂ more efficientÂ harvesting water resources inÂ supportingÂ the crop growing. TheÂ laboratory research studied the characteristic of various kind, thickness and ratio of hardplain material was carried out at Laboratory of Agronomy of UNSOED,Â Soil Mechanic of GMU.Â the SEM and X-RD ofÂ Lemigas Jakarta. Permeability determination by Falling Head which is appropriate measurmentÂ was not significantly different with ELE28-290 permeameter. Permeability of Kokap clay soil andÂ Nanggulan bentonite were larger than theÂ rainfall intensity in coastal sandy land.Â The Sentolo Vertisol content 68% calcium smectite had permeability 3,7 mm.day-1.Â Bentonite permeability were not significantly different due to more than 80% clay mineral composition. Therefore the permeability of natrium bentonite like asÂ BPIB andÂ BLUB namelyÂ 1.4 x 10-2 and 10-2Â mm day-1 were lower than the calcium bentonite like as RMBL and BLBKÂ permeability namelyÂ 4.3 x 10-2Â andÂ 2.43 x 10-2 mm day-1. Permeability of 0.5 cm thickness bentonite was notÂ significantly different than 1.0 dan 1.5 cm thickness and those had very low permeability. Bentonite sand mixture 15 and 20 percent produced bentonite sand agregateÂ thatÂ hadÂ mesopores by which allowing the drainage and available soil water so that those had water permeability 13.7 danÂ 10.3 mm day-1 respectively.Â The mixture 30-100%Â had not significantly different permeability namely 7.3 x 10-2Â up to 1.4 10-2 mm day-1. The combination of tickness and the low ratio ofÂ bentonite sand mixutre need to be determined to produce favourable environment in supportingÂ the plant growth.
