Abstract

Vanda Douglas orchid is the one of tropical famous plant especially in Indonesia. The beauty of Vanda Douglas orchid is attract people’s attention as an artifial plant, cutting flower, garden decoration and public facility. The aim of research to learn more about : KNO3 fertilization, cytokinin ZPT application which is using Benzyladenine (BA) with or without Thidiazuron (TDZ), detect if there is an interaction or no interaction between application of KNO3 and ZPT cytokinin, also shoot decapitation on the flowering of Vanda Douglas orchids. Research was held in Sanggar Bunga Douglas Kelurahan Sumur Putri, Kecamatan Teluk Betung Utara, Kota Bandar Lampung started from November 2021 to February 2022. First attempt did using a Group Random Design (RAK) with three repetation. The treatment was arranged using factorial 2x5 and the first factor was KNO3 which was K0 (no fertilizer) and K1 (10 g/l of KNO3), and second factor were variant concentrate of BA and TDZ (mg/l) : no ZPT as a control, 200 BA, 400 BA, 200BA+15 TDZ and 400 BA+15 TDZ. Each treatment combination was repeating for three times and every single research consisted of 10 Vanda Douglas orchids and the number of whole plants reach 300 of Vanda Douglas orchids. Second attempt was a factorial research with Group Random Design (RAK) consisted of 2 factor. The first factor was no shoot decapitation (P0) and with shoot decapitation (P1). Second factor were variant concentrate of BA : 0, 200, 400, 200 mg/l + 15 mg/l TDZ, and 400 mg/l + 15 mg/l TDZ. Each treatment combination was repeating for three times and every single research consisted of 10 Vanda Douglas orchids and the number of whole plants reach 300 of Vanda Douglas orchids. Data analyze did by using variant analyze and if showed the significancy, it would continued by BNT test on 5% level. Observation of first attempt started on second week after KNO3 and ZPT sprayed. Observation of second attempt started in week 24 ( or week 12 after shoot decapitation). Variable that observed were : percentage of flowery plant (%) grain length (cm) and number of bud. The result of research showed that combination between KNO3 fertilization and ZPT gave the tiny effect to Vanda Douglas orchid flowering. Application of ZPT (BA or BA+TDZ), shoot decapitation and interaction between both factors was effecting to flowery plant percentage. Only for average of grain length variable and number of bud, the variant analyze did for single factor which was ZPT application. It was caused by no shoot decapitation treatment the whole plants (120 plants) wasn’t flowery. The variant analyze showed that ZPT application had real effect to grain length and bud.

Abstract

Liang Tea Pontianak (LTP) is a functional drink made from several herbal leaves and sucrose as a sweetener. Sucrose has a sufficiently high calorie content that a reduction in sucrose consumption is necessary. Sweetener stevia is a natural sweetener that is sweeter and lower in calories, but the stevia it contains gives the aftertase a slightly bitter taste. Apples have medium sweet and sour properties so that they can be used to add to the taste of liang tea drinks. The purpose of this study was to obtain the ratio of stevia and sucrose in the formulation of LTP apple cider flavor based on physicochemical and sensory characteristics. The design used in this study is a randomized Group Design (RAK) which consists of one factor, namely the comparison of sucrose and Stevia Sweetener (s) with 3 replications and 21 treatment units. The comparison of sucrose and stevia sweeteners is 100%:0%, 99.82%:0.18%, 99.63%:0.37%, 99.44%:0.56%, 99.23%:0.77%, 99.01%:0.99% and 98.78%:1.22%.

Abstract

Sugarcane in Indonesia are very important economically because they were the main raw material for the sugar industry. To meet sugar needs, efforts are needed to intensify and extensify sugarcane cultivation, ensuring high productivity and yield. One of the expansions of sugarcane fields in Yogyakarta is fields with sandy soil. The planting system is an intensification effort, both with single rows and double rows, where each system has a different impact. This research aims to analyze the impact of sugarcane planting (single-row and double-row planting systems) on soil conditions and sugarcane yields on sandy land. This research used a one-factor Randomized Block Design (RAK) with two levels of treatment, namely single-row and double-row systems. Each level was repeated 6 times in blocks, with the land area of ​​one block being 50m2, so the total land area used for research was 300 m2. The analysis was carried out when the plants were 6 months old, by taking samples of 5 plants in each experimental unit and analyzing the Brix percentage, pol percentage, purity value, sap value, and yield. Soil samples were taken from a depth of 10-30 cm from each experimental unit and analyzed for moisture content, organic matter, soil pH, cation exchange capacity (CEC), available nitrogen, available phosphorus, and available potassium. The data obtained was then analyzed using a T-test at a 5% level and correlation analysis using SPSS. The planting system did not have a significant effect on organic C, pH, CEC, available nitrogen, available phosphorus, and available potassium of the soil. Single-row sugarcane planting provides higher and significantly different poll%, sap value, and sugarcane yield compared to double-row planting. There was a strong correlation between soil organic matter and the sugarcane yield content obtained (r=0.52). Maintaining soil organic matter is an alternative to maintain and increase the yield and yield of sugar cane plants.

Abstract

Rusip is a fermented fish product that has a distinctive aroma and taste depending on the fermentation time because it produces peptides and amino acids that contribute to the aroma and taste of rusip. This study aims to determine the optimal fermentation durations to produce rusip with good chemical and functional characteristics. This study used a completely randomized design with 4 replications and 5 treatments of fermentation duration (weeks), namely 0, 1, 2, 3, and 4. The observation parameters included pH, lactic acid bacteria (LAB), peptide content, water content, antioxidant activity, and glutamate acid. The data obtained were statistically analyzed using Barlett's test and Tuckey's test, followed by ANOVA test and Duncan New Multiple Range Test (DNMRT) test at 5% level. The test results on these parameters then selected the best treatment to be tested for protein content. The test results showed that the optimal fermentation time was 3 weeks with a pH of 5.55; moisture content of 62.67%; peptide content of 2.38%; glutamic acid 13.41%; antioxidant activity of 54.75%; the number of LAB 9.51 log CFU/g; and protein content of 15.03%.

Abstract

Sugarcane is one of Indonesia's leading plantation commodities. East Java, with the highest contribution to sugarcane plantations in Indonesia, is experiencing a downward trend in production and land area. Farmers experience a problem with limited capital. Credit is a solution to strengthen farmers' capital structures. However, credit uptake is still not optimal given the available ceiling. This study aims to analyze the factors that influence farmers' decisions to take credit and their effect on the performance of sugarcane farming in East Java. The data used is secondary data from the 2014 Plantation Business Household Survey. The respondents consisted of 1.040 credit farmers and 3.587 non-credit farmers. The methods used were logistic regression and Propensity Score Matching (PSM). The findings demonstrated that factors such as age, land size, seed varieties, cooperative membership, farmer group membership, partnership involvement, and association participation had an impact on farmers' credit decisions. Higher total production, revenue, costs, and income compared to non-credit indicate that credit has a positive impact on farm performance.

Abstract

This study aimed to determine the quality of dried butterfly pea flowers obtained by several post-harvest handling treatments. Post-harvest treatment of butterfly pea flowers according to SOPs includes harvesting, wet sorting, washing and draining, weighing, drying, dry sorting, and packaging. This study consisted of four post-harvest treatments, including P1 (without washing and sorting, direct sun drying), P2 (without washing and sorting, drying using food dehydrator), P3 (with washing and sorting, indirect sun drying), and P4 (with washing and sorting, drying food dehydrator). All treatments were analysed for dried flower quality, including water content, antioxidant content, and organoleptic quality.  The results showed that there was a significant difference in the moisture content of butterfly pea flowers with four post-harvest treatments.  P3 and P4 obtained lower moisture content than P1 and P2, which were 9.7% and 10.7%, respectively.   Washing, wet sorting, and dry sorting are part of post-harvest handling following SOPs.  The antioxidant content data showed no significant difference from the four treatments, but the highest free radical inhibition was obtained from the P3 treatment, which was 80%. From this study, it can be concluded that good post-harvest treatment of butterfly pea flowers consisted of harvesting activities, wet sorting, washing and draining, weighing, undirect sunlight drying or food dehydrator drying, dry sorting, and packaging.

Abstract

Nata de cacao has the potential to be packaged in plastic cups as a type of ready-to-consume product. However, its characteristics and shelf life was not yet known. This study aims to determine the characteristics of nata de cacao products in plastic cup packaging and to determine their shelf life. Estimation of the shelf life of nata de cacao products in plastic cup packaging using the Extended Storage Studies (ESS) Method with two treatments, namely without preservatives and with sodium benzoate preservatives. Freshly harvested nata sheets were soaked, washed, diced, boiled in syrup with treatments without adding Na-benzoate and adding Na-benzoate 0.75 g / l, put in a plastic cup and closed. A total of 10 cups of nata without preservatives were stored for 10 days and observed every day, while 10 cups of nata with preservatives were stored for 33 days and observed every 3 days. Sensory observations were carried out by 8 trained panel members including changes in color, appearance and consistency of syrup, aroma and texture of nata. In addition, pH measurements were also carried out. The results of the study showed that the characteristics of nata de cocoa in syrup packed in plastic cups were close to white in color, chewy texture, clear and non-slimy syrup, and non-sour aroma. However, during storage there tended to be a decline. Based on the consumer acceptance limit for the observed parameters, the nata de cocoa product in syrup without preservatives and packed in plastic cups had a shelf life of 5 days at room temperature. While with the addition of 0.75 g/l sodium benzoate preservative, it had a shelf life of 27 days.
