Abstract

Because of shelf life of salak madu fruit is relatively short and easily spoiled during storage, the fruit is difficult to sell. This study aimed to find the best emulsion combination from the addition of kecombrang leaf extract and sesame oil as an edible coating to preserve quality and extend the shelf life of the fruit. This study used a Randomized Block Design using two factors. The first factor was kecombrang leaf extract with concentrations level are (0%, 4% and 8%) while the second factor was sesame oil with concentrations level are (0%, 0,55% and 1%). Parameters tested were weight loss, color difference, total acid, total dissolved solids, texture and damage intensity. Observations were carried out for 16 days and all samples were storage at room temperature (28-31oC). The results showed that the single treatment of sesame oil influences the total acid, while the single treatment of kecombrang leaf extract has an effect on the color difference. The interaction of sesame oil and kecombrang leaf extract affects weight loss, hardness, total dissolved solids and damage intensity. The emulsion of kecombrang leaves extract 8% and sesame oil 1% was the best to inhibit the deterioration of salak madu’s fruit. This combination was able to inhibit the rate of change in texture, total dissolved solids and weight loss, but the combination could not inhibit the rate of change on total acid and the color of the fruit. Based on the value of damage intensity, kecombrang leaves extract 8% and sesame oil 1% treatment, could inhibit weight loss and hardness until day 10, while inhibiting fungal growth until day 9.

Abstract

The research aims to determine the effect of pulsing solutions and soaking time to extend the freshness of the white roses cut flower (Rosa hybrida L.) as well as to obtain the best treatments combination of the two variables. The research is consisted of 8 treatment combinations, each treatment was repeated 3 times to obtain 24 treatments. The research uses a completely randomized design (CRD) method with two experiment factors. The first factor is the component of the pulsing solution consisting of 3 parts: Sucrose 5% + 250 ppm AgNO3 + Citric Acid 75 ppm, Sucrose 10% + 500 ppm AgNO3 + Citric Acid 150 ppm and Sucrose 15% + 650 ppm AgNO3 + Citric Acid 300 ppm. The second factor is the immersion time consists of two parts, namely: 4 hours and 8 hours. The analysis was carried out every two days with replacement of water every two days stored at room temperature (27 ± 1)0C for 12 days. The combination of pulsing solution treatment and soaking time had a very significant effect (p<0.01) on the total absorption and had no significant effect (p>0,05) on changes in weight, color score test, withered, bent neck and efflorescence of level. The best combination of treatments solution pulsing treatment is 15% sucrose + 650 ppm AgNO3 + 300 ppm Citric Acid with 8 hours immersion resulting in an average total absorption of 10,48 ml, an average rate of weight changes 9,8 %, the average color test score was 3.2, the average wilt level test score was 3.6, the average bent neck test score was 3.6 and average rate of flowering 63,89%. It can be concluded that white roses are affected by the concentration of the pulsing solution because the concentration of the pulsing solution gives changes to white rose cut flowers.

Abstract

Sanur Kaja Village has a special waste management facility for processing waste produced by the village community, namely Depo Cemara. Based on previous research on the effectiveness of waste management in the Depo Cemara, it is known that in general these activities have been running well but are less efficient. This is because of the community has not done waste sorting and the application of the 3R principle at its source, which this is one of the assessment aspects. This study aims to identify the effectiveness of the waste management system that has been implemented by the people of Sanur Kaja Village by comparing the amount of waste managed by households with the 3R principle with the amount of waste wasted in order to obtain a percentage of waste reduction. Data collection was obtained by distributing questionnaires to respondents who were determined by purposive sampling technique. The data obtained were then calculated by analyzing the mass balance of waste and then further analyzed using descriptive statistical analysis methods. The results of research on 96 households show that community-based waste management is still not effective because the percentage of waste reduction that occurs in one day only 22,5% and respondents who sort household waste are 44%. The community agreed to the plan to implement the 3R principle in household waste management and considered it important to add supporting facilities for waste management.

Abstract

When the genetic, soil and cultivation technique are not limiting factors, the fluctuation of yield production is affected by the climate or environmental factors. The objective of this study is to observe the water availability effect (i.e., water deficit, rainfall, and rainy days) on the sex ratio, including the models of oil palm yield production. The study was carried out from November 2016 to October 2017 in the Wilmar International Plantation Region Central Kalimantan. Analysis using the multiple regression and correlation tests, including the classical assumption test (i.e., normality, multi-collinearity, and heteroscedasticity tests) for the statistical analysis in this study. The results show that the rainfall and rainy day significantly affect the sex ratio development during 23 months before harvest (MBH) when the water deficit significantly impacts the sex ratio at 24 MBH. While the estimation of distribution monthly production, budget production, and actual production was not significantly affected. Therefore, it can be used to estimate the monthly distribution production of oil palm accurately.
