Abstract

Starch-based bioplastics are safe for the environment. One source of starch that can be used is durian seed flour and cassava flour. Bioplastics made from starch have several disadvantages, so they need to be supported. One material that can be used for support is microcrystalline cellulose (MCC). This study aimed to determine the effect of mixing of durian seeds starch with cassava starch on the characteristic of bioplastic supported by MCC. This study used a Completely Randomize Design (CRD) with 5 treatments and 3 replications. Data were analyzed using analysis of variance (ANOVA) and continued with Duncan’s New Multiple Range Test (DNMRT) at 5% level. The treatment in this study was the mixing durian seeds starch with cassava starch (0%:100%, 20%:80%, 30%:70%, 40:60%, 50%:50%). The results showed that mixing durian seed starch with cassava starch significantly affected thickness and elongation. Based on the analysis of bioplastic characteristics, the best bioplastics were found in treatment E (addition of durian seed starch 50%: cassava starch 50%) with a thickness of 0.27 mm, tensile strength value of 7.17%, elongation of 0.13% and water absorption 91.46%.

Abstract

This study entitled "Effect of Atonic Concentration Doses and Cow Manure Dose on Growth of Oil Palm Seedlings (Elaeis guineensis Jacq.) Prenursery System". This study aims to determine the interaction and influence of atonic concentrations and doses of cow manure on oil palm nurseries (Elaeis guineensis Jacq.) In the prenursery system. This research was conducted at the Experimental Station of the Faculty of Agriculture, University of Warmadewa, with a height of 25 meters above sea level, which was carried out on 17 February 2019 to 18 May 2019. This research used a Randomized Block Design (RBD) with factorial patterns. The treatments that were tried consisted of two factors, namely: The first factor of atonic concentration consisted of: Z0: (Control), Z1: (Concentration of 1 cc l-1), Z2: (Concentration of 2 cc l-1), and Z3: (Concentration 3 cc l-1). The second factor is cow manure (P0) which consists of: P0: (Control), P1: (Cow Manure 15 g / polybag), P2: (Cow Manure 30 g / polybag), and P3: (Cow Manure 45 g / polybag). Thus there are 16 combinations of treatments. Each was repeated 3 times, so there were 48 oil palm seed trial units. Based on this research can be several things as follows : Research shows that the interaction between atonic concentrations and doses of cow manure on all variables observed has no significant effect. The treatment of atonic concentrations of 2 cc l-1 gave the highest average dry weight of the leaf oven at 2.87 g, an increase of 48.70% when compared with the lowest yield at the control atonic concentration of 0 cc l-1 at 1.93 g. The treatment of cow manure doses showed that in the nursery of the oil palm prenursery system all the observed variables had no significant effect.

Abstract

Basil leaves are small clumps of shrubs and have long leaves such as spurs that are widely favored by Indonesian people as fresh vegetables and rich in flovanoid compounds, tannins, safonins, and essential oils function as anti-microbial properties. This study aims to determine the characteristics of the flying fish due to the influence of the use of the concentration of basil extract and soaking time and find out how long the basil extract can maintain the freshness of the flying fish. This research was conducted at the Food Analysis Laboratory of the Warmadewa Faculty, Denpasar Veterinary Center, and LPPMHP Denpasar. This research is a factorial experiment with a randomized block design (RBD) consisting of 2 factors: namely factor I, duration of immersion consisting of 2 levels, namely 1 hour and 2 hours soaking. Factor II, storage time which consists of 3 levels: 2 days, 4 days and 6 days. Variables observed in flying fish include objective observations namely analysis of water content, pH value, Total Volatile Base (TVB) value, and Total Plate Count (TPC) value. Whereas subjective observations included tests on the appearance of eyes, appearance of meat, odor / odor, and texture. The best freshness quality of the flying fish is objectively obtained in the 2 hour immersion treatment with 6 days storage time in cold temperatures (10 ± 5) ˚C and subjectively the effect of each treatment on variables, appearance of meat, odor / odor, and the texture is still good and acceptable. Overall treatment test results compared with Indonesian National Standard No. 2729-2013 shows that the test results variable meets the requirements.

Abstract

The commodity of poultry that has the greatest potential to be developed is broiler chicken, this is because the growth rate is very fast so that the maintenance period is relatively short. Livestock productivity is influenced by 30% genetic factors and 70% environmental factors. One important environmental factor to consider is maintenance management, especially feed. Chicken feather flour is one of the wastes that can be used as chicken feed. The research design used was a Completely Randomized Design (CRD) with 4 treatments and 3 replications each test using 4 chickens. The four treatments are P0 = control ration without adding chicken feather flour, P1 = ration containing 2% chicken feather flour, P2 = ration containing 4% chicken feather flour, P3 = ration containing 6% chicken feather flour. The parameters observed were the weight of the carcass parts (chest, thighs, wings and back). The data obtained were analyzed by analysis of variance, if obtained significantly different data (P <0.05) will be followed by a multiple distance test from Duncan. Addition of chicken feather flour to broiler chicken ration gave no significant difference (P> 0.05) in the weight of carcass parts (chest, thighs, wings and back).

Abstract

This research was conducted with the aim to find out the type of stem borer and the percentage of attack, the type of parasitoid associated with eggs and stem borer larvae. The method used for larval sampling is purposive sampling method, namely deliberate withdrawal. Egg samples are obtained by capturing imago stem borer in the field using a sample bottle then the imago is put into a cage that has been prepared as a place of maintenance to produce eggs. For the purpose of calculating the percentage of stem borer attacks, the location of the sample is determined in rice plantations in the vegetative and generative phases which are spread over 6 planting sites with each location measuring 100 m x 100 m. At each location 5 sample plots were systematically diagonal shaped. Each sample plot consisted of 9 clumps of rice. The results found 5 types of stem borer namely Scirpophaga incertulas Walker, Scirpophaga innotata Walker, Chilo supressalis Walker, Sesamia inferens Walker and Chilo polycrhysus Meyrick. Found 1 type of stem borer parasitoid larvae, namely Stenobracon nicevillei Bingham. Three types of stem borer egg parasitoids were found, namely Tetrastichus schoenobii Ferriere, Telenomus rowani Gahan and Trichogramma japonicum Ashmead. It is known that the percentage of stem borer attacks is 11.94% in the vegetative phase and 11.60% in the generative phase.

Abstract

Plankton is instrumental in the aquatic ecosystem, plankton can be an indicator of fertility and pollution. The quality of a water especially the flooded waters can be determined based on the fluctuations of the plankton population that will affect the trophic levels of the waters. The quality of a water can be measured by knowing the value of the Saprobic Index (SI). The Saprobic index is an index that closely relates to the pollution level. This research aims to determine the level of fertility and pollution levels in the waters of Telaga Tunjung Dam, based on the status of Trophic and Saprobic's structure of Phytoplankton, knowing the relationship (linkage) of trophic status and structure Saprobic phytoplankton with variable water quality in Telaga Tunjung Dam. The methods of study used are descriptive methods of case study. The research was conducted on five stations with four repetitions. Plankton sampling performed actively using plankton net with mesh size 60 μm diameter 25 cm. Based on the results of the status of the trophic waters in Telaga Tunjung Dam is at the head of high Water Fertility (Eutrofik). The pollution level is mild to moderate water with a saprobic index from 0,739 to -0,583. The trophic level relationship and the saprobic structure with the water quality variable show that good water quality affects the abundance of high phytoplankton and mild to moderate pollution levels.
