Abstract

Indonesia have many local chicken, such as merawang chicken and arab chicken. Arab chickens are layer local chicken that has egg production more than merawang chicken. Crossing between merawang arab chicken and arab merawang chicken aimed to improve genetic quality through heterosis effect. Interse of merawangarab (MAMA) with interse of arab merawang (AMAM) were observed for their production traits. Total of 98 MAMA chickens and 46 AMAM chickens were observed for their body weight, feed consumption, feed conversion and mortality.This research used covariance (ANCOVA) in randomized complete block designed (RAK). Chicken crossing as a treatment and concomitant is DOC weight. The body weight of MAMA and AMAM were not different (P>0.05). Body weight MAMA male and female at age 10 weeks were 843.10 g and 763.5 g respectively. Body weight AMAM male and female at age 10 weeks were 825.82 g and 741.2 g respectively. Feed intake and feed conversion of MAMA and AMAM male were not different (P>0.05) as well as MAMA and AMAM female. Mortality were occurred in early rearing phase of AMAM chicken was 2.2%. Performance of MAMA and AMAM chicken at age 1-10 weeks were same.

Abstract

Panthera tigris tigris is a subspecies of Panthera tigris, which originates from India and has been declared an endangered species. Bengal Tigers are facing a severe decline in their habitat and population. Ex-situ conservation of Panthera tigris tigris has been done in some Indonesian zoos to enhance its population. Serulingmas Zoo is one of the ex-situ conservation sites. This study aims to observe the tigers’ daily behavior in captivity as a conservational database. Behaviors of Bangla tigers (Panthera tigris tigris) in captivity were investigated from February to March 2021 in Serulingmas Zoo, Banjarnegara. Instantaneous Focal animal sampling has been conducted to observe the seven tigers. The results showed that the behavior could be divided into Moving, feeding, resting, social and other behaviors (including drinking, urinating, grooming, stretching, and defecating). The daily behavioral patterns showed resting behaviors as the most significant (33.56 %). The pacing activity (24.43%) counted as a frequent one that showed the tigers had altered their natural behavior. The eating and social 16.42%, and 13.03%), respectively. Defecating was reported as a minor activity (0.22%). Generally, the daily behaviors of Bangla tigers captivated at Serulingmas zoo showed the alteration in behavior patterns.

Abstract

The sophisticated communications could be a tool as a driver to increase of the illegal wildlife trade. Since 2012 there has been a shift in the trend of illegal wildlife trade from the offline market to the online market (advertising, e-commerce and social media). This study aims to determine the role of new media in the dissemination of Indonesian Council of Ulama (MUI) Fatwa No. 4/2014 about The Protection of Endangered Species for the Balance of the Ecosystem (illegal wildlife trade fatwa). The research was carried out in April–August 2020 through the new media Facebook. Collecting wildlife trade data through Google trends for a period of 5 years (2015-2020). Google trends are used as a basic reference in determining targets for video dissemination through Facebook. The approach used is by using research methods through new media, content analysis resulting from video dissemination (such as impressions, engagement, opinions, and feelings). The results of the study show that new media can be an effective medium in conveying and developing conservation messages, particularly to reduce the illegal wildlife trade in Indonesia.

Abstract

Sentul and kampung chicken are known as dual-purpose chicken, and kedu chicken is as laying hens. The crossing of sentul, kampung and kedu chicken produced SKKedu chicken. The crossing is expected to be produced local chickens that have superior meat quality from the combination of the three types of chicken. This study aimed to analyze the physical quality of SKKedu chicken meat. Tests were carried out on the flesh of the chest, upper thighs and lower thighs of 12 SKKedu chickens aged 12 weeks. Analysis of the meat physical characteristics included 4 variables pH value, cooking shrinkage, tenderness, and percentage of water binding power. The pH value of SKKedu meat in the upper thighs and lower thighs were the same (P> 0.05), while the breast meat was significantly different (P <0.05). The tenderness is only done on breast meat and obtained a value of 2.86 ± 0.50 kg cm-2. The different parts of meat did not have a significant effect (P> 0.05) on cooking losses of SKKedu chicken meat. Power binding to water (DMA) of breast and lower thigh meat was different (P <0.05) with the best DMA in the lower thighs. SKKedu chicken meat was still quite tender.

Abstract

Bioplastics, an environmental friendly materials, attracting interest to many scientists around the world. Cassava starch may used as a major ingredient for bioplastics production. The addition of cellulose could improve the quality of starch base bioplastics. Cellulose used for thispurpise is mainly extracted from wood. Extraction of cellulose from wood materials is not easy. Removing contaminant particularly lignin is the major obstacle. The use nata de coco, a pure crystalline cellulose, may of great choice to replace cellulose of wood origin. It is the aim of this study to search the possibility of using nata de coco as filler replacing cellulose of wood origin for the production of bioplastic using cassava starch. The effect of nata de coco as a filler on the quality of bioplastics was studied using a Central Composite Design (CCD) and Response Surface Analysis (RSA). The ratio of tapioca and nata de coco and the ratio of nata de coco and glycerol were evaluated. The performance of bioplastics was measured semi qualitatively based on the structure, color, and its similarity to synthetic plastics. The result shows that the quality of bioplastics affected by nata de coco linearly when the maximum of nata de coco used up to 40% (v / v). Bioplastics may be prepared using 10% (w / v) tapioca, 3% (w / v) glycerol and 40% (v / v) nata de coco. The average degree of swelling of bioplastics is 18.75%, an average tensile test of 0.01494 kgf / mm2 and an average elongation 14.4056%. The results of this study indicate that nata de coco may be used as a filler in the manufacture of starch-based bioplastics re placing wood based cellulose.

Abstract

Indonesia has a variety of local chicken famincluding merawang chicken and arabic chicken. Merawang chickens have potential as dual-purpose type chickens and laying types for arabic chickens. Crossing the merawang chicken with arabic chicken is expected to be an alternative to increase the productivity of local Indonesian chickens through increasing the genetic material of local chickens and developing local chickens. Appropriate feed supports livestock productivity performance. This study aimed to examine the growth performance of merawangarab chickens with 50% merawang and 50% arabian genetic composition fed mixed feeds with commercial feed compositions for broilers with different rice bran from the 4th week to the 12th week. The number of DOC used as many as 80 tails and not differentiated by sex, 60% of the feed used; 80%: 100% commercial broiler feed for starter phase mixed with 40% rice bran; 20%; 0%. The study used a Randomized Block Design (RAK) with a hatching period as a group. The variables measured were feed consumption, body weight, feed conversion, and mortality. Feed and drinking water are provided ad libitum. The results showed that the performance of merawangarab chickens with different compositions of commercial feed and rice bran was the same (P>0.05) for all growth variables. The average body weight at 12 weeks of age was 1064.6-1167.8 g. In conclusion, the growth of merawangarab chicken by replacing commercial feed up to 40% with rice bran is still good.

Abstract

Butterflies are one type of insect that functions as a pollinator. Research on butterflies in the Bodogol Nature Conservation Education Area (PPKAB), has already been published, but research on the correlation of butterflies with flowering plants has not yet been published. The purpose of this study was to determine the correlation between butterflies and flowering plants in the PPKB area. The research was conducted in February-June 2022 in heterogeneous and homogeneous forests. The research was conducted using purposive sampling method. In each observation, 10 plots were observed in heterogeneous on 3 lanes (Rasamala, Canopi, and Aprika), and in homogeneous forest on 3 lanes (Cikaweini-Cipadaranten, and Gembong koneng). Research using cameras and insect nets. In this study, 78 species, 4 families with 261 individuals were found in heterogeneous forests, and 39 species, 5 families with 158 individuals in homogeneous forests. Butterfly families: Papilionidae, Pieridae, Nymphalidae, Lycenidae, and Rionidae. The Nymphalidae family is one of the families with the highest number of species and individuals compared to other families. Based on the index value of butterfly diversity, it is classified as high (heterogeneous) and medium (homogeneous). High evenness index in both habitats. Jamides celeno is one of the dominant species in both habitats. Correlation analysis showed that there was a strong relationship between flowering plants and the number of individual butterflies in both habitats (heterogeneous and homogeneous).

Abstract

Elderly is one of the processes of a person who has entered the final stage of the life phase. Groups categorized as elderly experience a process called the aging process. The nutritional adequacy rate is the average daily nutritional adequacy. Nutritional adequacy is an indicator of food security at the household level and can be measured by the adequacy of energy, protein and fat. The study aims to analyze the cases of nutritional adequacy of the elderly. The method used a quantitative method using a cross-sectional approach that is complemented by interview techniques using a food recall questionnaire. This study shows that the average level of adequacy of energy, and macronutrients (carbohydrates, protein and fat) is included in the sufficient category, while fiber still needs to be improved, because it is included in the insufficient category. The nutritional status of respondents was mostly normal, although some were in the obese category. to maintain a healthy body, an elderly person needs to do routine activities and have food quality by showing the suitability of food intake based on recommendations, namely the existence of a variety of food groups, nutritional adequacy according to needs, moderation and overall balance.
