Abstract

The Phycochemical Study of Kristal Guava (Psidium guajava L.) During Storage under Difference Cultivation Techniques and Fruit Maturity Levels. Kristal guava (Psidium guajava L.) is one of guava variety with high economic value, thick flesh and seedless. This research studied the effects of cultivation techniques and maturity level toward the physical and chemical characteristics of kristal guava during storage. Research was conducted at the farmland in Banjar Semanik, Pelaga, Badung and the storage was implemented in Postharvest Engineering Laboratory, Faculty of Agricultural Technology, Udayana University in April to December 2016. This study used a completely randomized design (CRD) with two factors and the treatments were repeated four times. The first factor was with 2 levels of cultivation techniques (non intensive and intensive) and the second factor was with 3 levels of maturity (green, light green and yellowish green). The results showed that there were interaction between cultivation techniques and maturity level toward the physical and chemical characteristic of kristal guava in average weight per fruit and the organoleptic test color of the fruit observed 9 day after storage. The highest average weight per fruit (248.33 g) was obtained from combined treatment of intensive cultivation techniques with the third maturity level which is yellowish green was significantly different with the lowest average weight per fruit (143.33 g) that was obtained from combined treatment of intensive cultivation techniques with the first maturity level which is green. The best combined treatment that affect the physical and chemical characteristics of kristal guava during storage is combined treatment in intensive cultivation techniques with the third maturity level which is yellowish green, but statistically not significantly different from non intensive cultivation technique.

Abstract

Learning about integrated farming could be done by visiting site locations directly. This is a problem for universities that are located in urban areas. The distance of the integrated agricultural location from the campus often raises a significant cost burden. Therefore, providing a learning model around the university would be more efficient, and students could interact and practice directly. The design concept was compiled based on a literature review. The design was produced by direct observation at Condongcatur experimental garden, then continued SWOT analysis. The design was created using software based on the information gathered. The design development included a general description of the experimental garden, landscape biophysical aspect, concept planning, and design. The resulting design was then validated by experts descriptively using a questionnaire. Meanwhile, user acceptance was measured qualitatively through an interview. Based on the results obtained, theoretically, a small-scale integrated farming design has been successfully compiled and met the requirements to be developed as an agricultural learning model. The design also received a good response from the management, which would then be followed up in the long-term development plan of the experimental garden.

Abstract

Bali is one of the grape-producing regions in Indonesia, and grape cultivation is carried out in the North Bali area of Buleleng Regency. Grape growers in Bali began to plant other grape varieties, namely green grapes (Vitis vinifera L. var. Muscat Saint Vallier). This grape variety originates from France and grows successfully in the tropics. Currently, there needs to be more information about the yield potential and quality of green grape varieties. This study aims to determine the productivity and quality of green grapes at several harvest periods and locations. The research was conducted from January 2021 to September 2022 at three sub-district locations: Gerokgak, Kalisada, and Seririt. The research was conducted at six locations, namely Gerokgak 1, Gerokgak 2, Gerokgak 3, Kalisada 1, Kalisada 2, and Seririt. Data collection was carried out during three pruning to harvest periods: January–March, April–June, and July–September. Harvest period and planting location show a significant influence on green grape productivity. Observations on grape productivity in different years showed no significant results, and there was no interaction between location and harvest period. The harvest period for two consecutive years shows that the July–September harvest period gives the best yields. The quality of the yield of green grapes shown in the fruit obrix at both locations at different harvest periods shows that the obrix of this variety remains the same.

Abstract

This research aims to examine the viability of sunflower seeds against different drying methods and fungicide applications. This experiment consisted of two factors with a Completely Randomized Design (CRD). The first factor is the drying method, namely drying in the sun (control) with an average of 31°C for six days, cake oven and costume oven with temperatures ranging from 36.5-37.5°C for four days. The second factor is the application of fungicides, namely without fungicides and fungicides. Seed quality testing is carried out using the UKDdP method. The experiment consisted of 6 treatment combinations which were repeated three times so that there were 18 experimental units. Each experimental unit used 25 seeds. The results showed that the lowest water content was 6.25% from sun drying and the highest germination rate was 73.33%. The sun drying method and the use of fungicides can produce the lowest water content, and have the highest values ​​in the percentage of germination, vigor index, maximum growth potential, normal dry weight of sprouts, as well as the use of fungicides. It is necessary to test the temperature and drying period using a cake and custom oven to get the right time to maintain seed viability.

Abstract

Phytoremediation is usually applied to passively treat Acid Mine Drainage (AMD) by constructing a wetland. To increase the success of the AMD treatment method, laboratory trials were carried out on a pilot scale, and the experimental results were applied on an actual scale. Therefore, a simple design will be prepared for this research that replicates the wetland work system. This research aimed to produce a prototype that could be used for initial testing of phytoremediation on a smaller scale before being applied to field conditions. The installation design was created using Adobe Illustrator software. The trial lasted two months, using modified acid water and flowing it periodically as controlled droplets via an infusion tap into the media that used Typha sp and Pistia stratiotes L as phytoremediator agents. This equipment was tested with three acidity levels, 4, 5, and 6, repeated twice for two months. Results showed that the prototype was built using three buckets arranged in layers, each with its function. The phytoremediation process had successfully occurred in this study, and installation was suitable to support the process. There was a change in AMD acidity around the plants for five weeks and an increase in acidity the fourth week after treatment at the outlet. It could be seen that AMD with lower acidity levels resulted in greater plant damage in the sixth week, but Typha sp still showed resistance to an acidic environment.

Abstract

Rice (Oryza sativa L.) is the main staple food commodity in Indonesia. This study aimed to evaluate the seed quality of several local rice varieties obtained from e-commerce, based on standard seed quality parameters. The experiment was conducted using a Completely Randomized Design (CRD) with a single factor consisting of five local rice varieties: Rojolele, Sedayu, Mentik Susu, Ketonggo, and Jeliteng. Each treatment was replicated four times, resulting in 20 experimental units. The assessed parameters comprised seed moisture content,vigor index, germination percentage, maximum growth potential, pure seed content, proportion of other crop seeds, inert matter content, and seed health (pathology) assessment. The results showed that the Ketonggo variety had the lowest moisture content and the highest germination rate, vigor index, and maximum growth potential. The Mentik Susu variety exhibited the highest percentage of pure seeds and the lowest percentages of other crop seeds and inert matter. The was non-compliant with the established genetic quality standards with a pure seed percentage of less than 98%. Three types of fungi were identified using the blotter test method, namely Aspergillus niger, Aspergillus flavus, and Alternaria sp.

Abstract

Rapid Multiplication Technique (RMT) is a technique used to produce large scale cuttings of sweet potato in a short period by using mini cuttings and proper fertilizer management. The research was carried out from October 2019 to March 2020 and composed of two experiments The first experiment involved a randomized complete block design, with clones (“Ase Kapas” and “Ase Merah”) as the first factor, and tuber weight (150 ± 25 g, 250 ± 25 g, and 350 ± 25 g) as the second factor. The second experiment was arranged in a split-plot design involving different doses of NPK compound fertilizer (as main plot) and different source of cuttings (as subplots). The different doses included NPK 16:16:16 at 100 kg.ha-1 (0.3 g per polybag), 200 kg.ha-1 (0.6 g per polybag), 300 kg.ha-1 (0.9 g per polybag), and without fertilizer as control. The source of cuttings were from the tip, middle and bottom stem of the plants. Results showed that the “Ase Kapas” showed the highest number and the longest shoots, number of nodes, and length of vines. Additionally, tuber weight of ± 350 g produced the highest number of shoots. When it comes to NPK compound fertilizer treatment, a dose of 0.9 g per polybag increased cutting production in “Ase Kapas”, and also responded better to fertilizer treatment. On the other hand, dose of 0.3 g increased cutting production in “Ase Merah”. “Ase Kapas” produced more cuttings from the middle stem, whereas “Ase Merah” produced more cuttings from the . The application of RMT in “Ase Kapas” produced cuttings with ratio of 1:31, which is higher than those in “Ase Merah” with a ratio of 1:17.
