Abstract

Rambutan is one of the potential fruits to be developed. It is because Rambutan contains many compounds that are beneficial to the body. Rambutan is easily damaged if stored at room temperature. To maintain the quality and shelf life of rambutan requires a variety of techniques one of which is the temperature setting during storage. The damage of Rambutan starts from damage to the skin and fruit hair. Fresh-Cut is one way that rambutan fruit can be consumed in a longer time. Freshcut is a treatment by removing parts that are not consumed in the fruit through the process of stripping, cutting, slicer and so forth. This research was conducted using the complete random design method of factorial and 2 repeats. The first factor includes the long storage of Rambutan fruit consists of 6 levels, namely 0, L, 2, 3, 4, 5, 6. The second factor is the storage temperature of Rambutan fruit consists of two levels of cold temperature (7-12) ï‚°C and freezing temperature ((-4)-0)ï‚°C. Observations conducted objectively include: moisture content, pH, TSS, Vitamin C. Whole fruit storage and fresh-cut rambutan preferably at a temperature of 7-12ï‚°C with a closed packaging. Whole fruit even though the skin has changed brown but the fruit characteristics in it is still good until Day 6, while the best characteristic of Fresh-cut Rambutan until day 3.

Abstract

The provision of adequate quality and quantity rations is expected to increase the productivity of broiler chickens. One effort to improve ration quality is to add chicken feather flour in the making of rations, because chicken feather flour is rich in crude protein. The purpose of this study was to determine the effect of giving chicken feather flour in broiler rations aged 2-5 weeks to the growth of broiler chickens and to find out how much the level of chicken feather flour can give the results of body weight gain, final body weight, feed consumption and feed conversion. best. This study uses a completely randomized design (CRD) with 4 treatments and 3 replications. Each test used 4 CP 707 broilers aged 2 weeks with homogeneous body weight. The four treatments were ration without chicken feather content as a control and ration containing chicken feather flour 2%, 4%, and 6%. The parameters observed were body weight gain, final body weight, feed consumption, and FCR (Feed Conversion Ratio). The data obtained were analyzed by analysis of variance. If between treatments showed a real effect, then proceed with the smallest real distance test from Duncan (Steel and Torie, 1989). From the results of this study it can be concluded that the provision of chicken feather flour in broiler chicken rations had a significant effect on body weight gain and final body weight, but gave no significant effect on initial body weight, FCR and ration consumption.

Abstract

Motivation is the impetus for someone to do something in various activities for which he is responsible. Job satisfaction concerns an individual's general attitude towards his job. Someone with a high level of job satisfaction shows a positive attitude towards their work, while commitment is a level of loyalty to someone like an employee who works optimally for his company. The leaders in the quality control division must pay attention to this, because the motivation given to the quality control division employees is still lacking. In addition, employees with low commitment will also affect their performance. This needs to be considered because the quality control division is an important division and is directly related to the sugar production process. This study aims to determine the effect of motivation, satisfaction and work commitment in the quality control division at PT PG Candi Baru. This research was conducted at PT PG Candi Baru Sidoarjo using primary data. The data collection method used is by conducting interviews and distributing questionnaires to a sample of employees who have worked for at least 5 years. The analysis used in this research is descriptive analysis and correlational analysis. The results showed that motivation and job satisfaction can improve employee performance in the quality control division at PT PG Candi Baru Sidoarjo, while commitment to the organization has not been able to improve employee performance in the quality control division at PT PG Candi Baru Sidoarjo. Motivation, satisfaction and work commitment influence 40% of employee performance, while the remaining 60% are other variables not mentioned in the research.

Abstract

The provision of adequate quality and quantity rations is expected to increase the productivity of the quail. One of the efforts to improve the quality of the ration is by adding fermented bean sprouts waste flour to the ration making, because fermented bean sprouts waste flour is rich in crude protein. The purpose of this study was to determine the effect of giving fermented bean sprouts flour waste in the ration on the appearance of female quail and to determine at what level the provision of fermented bean sprouts flour waste in the ration had the greatest effect on the appearance of female quail. This study used a completely randomized design (CRD) with 4 treatments and 3 replications. Each test used 3 female quail with homogeneous body weight. The four treatments were rations without fermented bean sprouts flour waste as a control and rations containing 5%, 10%, and 15% fermented bean sprouts flour. The parameters observed were initial body weight, body weight gain, final body weight, feed consumption, and FCR (Feed Conversion Ratio). The data obtained were analyzed by analysis of variance. If between treatments shows a significant effect, then proceed with the smallest real distance test from Duncan (Steel and Torie, 1991). Based on the results of the research and discussion, it can be concluded that the addition of fermented bean sprouts flour in the grower-layer phase of female quail ration has an insignificant effect on all variables such as initial body weight, body weight gain, final body weight, ration consumption and FCR (Feed Converstion Ratio).

Abstract

Snakehead fish (Channa striata) is a freshwater fishery commodity in Indonesia which has a high protein content. Many studies on the benefits of snakehead fish have resulted in an increase in the amount of demand for these fish. One of the production factors that support fish farming is feed. The snakehead fish seeds have an average length of 2 cm, with rudimentary digestive organs. Therefore, the most suitable feed as seed feed is natural food. Commonly used natural feed is water fleas (Daphnia sp.) and silk worms (Tubifex sp.). This study aims to determine the effect of a combination of feed on the growth of snakehead fish seeds and to determine the combination of feed that gives the highest growth in snakehead fish seeds. This research was conducted at the Fisheries Resources Development Laboratory, Warmadewa University for 60 days, from March to April 2020. The method used in this study was an experimental study using a completely randomized design (CRD) with six treatments and three replications. The analysis used in this study was Analysis of Variance (ANOVA), and continued with the Least Significant Difference (LSD) test. The results showed that there was an effect of combination feeding on the growth of snakehead fish as indicated by the increase in absolute weight and length. And the sixth treatment is a combination of feed that provides the highest growth in snakehead fish seeds.

Abstract

This research is a field experiment conducted in paddy fields in Sumerta Village, East Denpasar District, with a place height of 40 meters above sea level, with an average temperature of 25-30 oC, which was carried out from 1 May 2018 to 4 June 2018. The purpose of this study was to find the influence of the concentration of liquid organic fertilizer biomi with urea fertilizer on the growth and yield of mustard plants. This experiment used a randomized block design (RBD) with a factorial pattern, which consisted of two factors, namely: the concentration of liquid organic fertilizer biomi (B) and urea (U). The first factor, the concentration of liquid organic fertilizer biomi (B) consists of 4 levels: B0 = (0 ml l-1), B1 = (2.5 ml l-1), B2 = (5 ml l-1), B3 = (7.5 ml l-1). The second factor, the dose of urea (U) consists of 2 levels: U0 = (0 kg ha-1), U1 = (50 kg ha-1). Based on the results of this study, we can conclude the following: the interaction of liquid organic fertilizer dose biomi with urea fertilizer has no significant effect on all observed variables. The administration of 50 kg ha-1 urea fertilizer (U1) gave the fresh weight of the crop per plant ie 99.85 g, increasing by 28.57% compared to without urea fertilizer. The treatment of liquid organic fertilizer biomi concentration of 7.5 ml l-1 (B3) gave the highest yield that can be seen from the highest fresh weight of the crop which and the highest weight of the economic yield is 93.63 g and 80.90 g

Abstract

This study aims to determine the effect of rabbit compost and NPK Mutiara dosage and their interactions on the growth and yield of cucumber plants. The design used in this study was a randomized block design (RBD) with 2 factorials. The first factor is the provision of rabbit compost fertilizer with 3 levels (0, 10, and 20 ton ha-1) and the second factor is giving NPK Mutiara fertilizer with 3 levels (0, 150, and 300 kg ha-1). The interaction between rabbit compost and pearl NPK had no significant effect on all observed variables except for the fruit fresh weight variable, which had a significant effect. The treatment of rabbit compost (K) had a significant to very significant effect on all observed variables, except for the variable number of fruits per plant and staged oven dry weight, which had no significant effect. The treatment of NPK pearl fertilizer (M) statistically has no significant effect on all observed variables, except for the variable fresh weight of fruit and dry weight of the staged oven which has a significant effect. The highest fruit fresh weight was obtained at the interaction between the dose of 20 ton ha-1 rabbit compost with a dose of 300 kg ha-1 NPK pearl of 6322.42 g or an increase of 150.36% when compared to the interaction between without rabbit compost and NPK pearl of 2525.37 g. Provision of rabbit compost of 20 ton ha-1 and NPK pearl 300 kg ha-1 can be suggested to increase the fresh fruit weight of cucumber plants.
