Karakteristik Fisikokimia, Mikrobiologi, dan Uji Pasar Yogurt Smoothies Rosela Stroberi pada Usia Remaja dan Dewasa di Bogor
Get PDFYogurt is a dairy product that is processed into a fermented drink using lactic acid bacteria. Smoothies are drinks made from fruit or vegetables containing milk, yogurt, or honey. Strawberry Rosella Yogurt Smoothie is yogurt that has been processed by reducing the water content and adding rosella flower extract and strawberry jam. Before being marketed, these products need to be tested for safety and market opportunities. This study aims to analyze the physicochemical characteristics, microbiology, and market tests of strawberry rosella yogurt smoothies in adolescents and adults in Bogor. The physicochemical characteristics tested included pH, water activity (aw), viscosity, and total titrated acid. The microbiological parameters tested were total lactic acid bacteria and Salmonella sp. The market parameters tested include analysis of consumer perceptions and preferences and their correlation with yogurt consumption patterns. The market test was carried out using 100 respondents consisting of 50 students from SMAN 1 Bogor and 50 students from IPB University. The results showed that the physical properties (pH, water activity, viscosity, and total lactic acid) fulfilled the SNI yogurt quality requirements. The chemical properties or nutritional content and microbiological properties of yoghurt smoothies have met the requirements for yoghurt quality standards based on SNI. The results showed that respondents had good perceptions and preferences on the attributes of smoothie yogurt. Consumer preferences regarding the appearance of the packaging in general, color, ingredient content, packaging information, and appearance of the contents of the yogurt are generally positively correlated with the price range of yogurt that consumers buy. Strawberry Rosella Yoghurt Smoothie is safe for consumption and can be marketed.

Perbedaan Jumlah Mata Tunas per Stek dan Populasi pada Pertumbuhan dan Produksi Bibit setelah Panen Ubi Kayu
Get PDFLimitations of cuttings become an essential problem in the expansion of cassava plantations. One strategy that can be taken is to reduce the length of the cuttings and increase the plant population to increase the area planted and produce more stems per unit area for the next growing season. This study aimed to determine the effect of cutting length and plant population per hectare on the growth and production of cassava stems. The research was carried out at the Jambegede Agricultural Technology Research and Assessment Installation in February–December 2020. The treatment consisted of two factors, namely three levels of cutting length (2, 4, and 10 buds/cutting) and three levels of the population (10,000, 30,000, and 40,000 plants/ha). The experiment used the Malang-4 variety and was applied to a completely randomized split-plot experimental design of three groups with the population as the main plot and the number of buds as sub-plots. The results showed that the number of buds/cutting increased the number of growing plants, one and three-month plant height, the number of viable stems, the length of unfit stems for seedlings, and decreased the percentage of dead plants. On the other hand, plant population/ha increases the percentage of dead plants, stem length unsuitable for seeds, and number of stems suitable for seeds. The interaction between the number of buds/cutting and the population was seen in the diameter of the three-month-old stems, the number of stems unsuitable for seedlings, the number of plants grown, the number of dead plants, and the number of plants harvested.

No full textThis study aims to describe the status of soil fertility and corn yield on different slopes of agricultural land in UPT SP3 Saritani Village, Boalemo Regency. The study used survey methods at 3 land slope locations (20--30%, 30–40%, and 50–60%), determined purposively. Soil samples and maize yields were analyzed quantitatively and descriptively. Corn yields were collected and compared over 3 harvesting seasons based on the parameters of agronomic components. Soil fertility was analyzed at BSIP PALMA Manado laboratory, with parameters including macronutrient components. An essential finding of this study is that there is a difference in corn yield and nutrients on the sloping lands. The fertility status of farmers\u27 land on the average sloped land of the three stations is very low levels of nitrogen and carbon nutrients and high levels of phosphate and potassium. The agronomic components of Stations 1 and 2 were relatively similar compared to the yield of components at Station 3. In the 3 harvest seasons, Station 1\u27s yield decreased every season; from Station 2 it also decreased, but only at the time of the third harvest, although it was insignificant. The yield from Station 3, the steepest field, decreased significantly.

Respons Tanaman Padi Pada Media Tanam Tanpa-Tanah Berbasis Irigasi Berselang
Get PDFRice cultivation without land as an urban farming method is carried out to produce food in a subsistence manner. This experiment aimed to examine the response of rice plants to non-soil planting media based on alternate wetting-drying irrigation. This work was conducted at the screen house in Sumberjeruk Village, Jember Regency (8°07\u2742.9" S and 113°47\u2709.3" E) from January to May 2022, using a factorial, fully randomized design of 2-factors with 3-replications. The planting medium without soil (husk:water) as the first factor consists of 4 compositions (v/v): 0:1, 1:4, 1:6, and 1:8 (total volume of 25-L media), while variety as the second factor consists of Inpari 46 and IR 64. The results showed that the combination treatment (husk: water) 1:6 and Inpari 46 had a significant effect on the number of productive tillers (25.17 stems) and grain weight per hill (34.07 g). The planting medium of non-soil husk: water 1:6 gave no significant value to husk: water 1:4 on the total number of grains (124.21 grains) and full grains (83.52 grains). The Inpari 46 varieties showed the highest value for the total number of grains (133.07 grains), the number of full grains (84.88 grains), and the weight of 1000-seeds (22.43 g). The application of husks and water as a planting medium with the right ratio is an ideal medium for landless rice cultivation since it can supply oxygen to the media.

Pengaruh Aplikasi Bioarang dan Zeolit pada Fluks CO2, Populasi Mikrob, dan Aktivitas Enzim Mikrob pada Gambut
Get PDFOil palm plantation on peatlands is considered to contribute to increasing global warming by releasing CO2 as one of the greenhouse gases that cause global warming. The addition of ameliorants, such as biochar and zeolite, can absorb CO2 from soil respiration and store and filter it in their molecular pores. This research aimed to study the effect of ameliorant application on the CO2 flux, water content, microbial population, and enzyme activities. Ameliorant was applied to peat soil with two factors. The first factor was an ameliorant combination with 6 treatment levels: control (A0); zeolite (A1); biochar (A2); zeolite:biochar 75:25; zeolite:biochar 25:75; zeolite:biochar 50:50, and the second factor was 3 levels dose of treatment (% w/w): 1.5%, 3%, and 4.5%. Peat flux CO2 and water content were measured monthly for four months in the laboratory. Without mixing with biochar (A1), the results showed that zeolite suppressed CO2 flux and suppressed the decrease of water content better than other ameliorant combinations. However, different ameliorant dosage percentages did not show any significant results. Ameliorant application and incubation affected the microbial population and enzyme activities, and the results were varied. Chemical characteristics changed after 4 months of incubation. In conclusion, our results indicate that only zeolite amendment can suppress CO2 flux and decrease water content but did not affect microbial population dynamics and enzyme activities.

Get PDFThe balance of ecological and economic utilization plays a real role in maintaining the stability of turtle nesting habitat on the coast. This study aims to calculate the suitability index and visitation carrying capacity (DDK) of sea turtle nesting habitat to maintain the sustainability of its population. The survey was conducted in December 2020 to January 2021 at Batu Kumbang Beach, Pulau Baru Village, Muko-Muko Regency. The analysis used was the Habitat Suitability Index (IKH), Tourism Conformity Index (IKW), and visitation carrying capacity (DDK). The Mukomuko Turtle Conservation Nature Lovers Community (KPAKPM) reported that this beach is still predominantly used as a nesting habitat for green turtles (Chelonia mydas), olive ridley sea turtles (Lepidochelys olivacea), hawksbill turtles (Eretmochelys imbricata), and leatherback turtles (Dermochelys coriacea) in 2018. At least 35 heads of various types landed and laid eggs here and further decreased in 2020 with only 17 heads. The IKH showed that about 84.06%, 75.36%, and 75.36% belonged to the highly appropriate category and were spread out at Stations 1, 2, and 3, respectively. The suitability of the coastal area is at a value of 2.0 ≤ IKW < 2.5, and is categorized as sustainable. The number of visitors allowed according to DDK is only 84 people per day. Batu Kumbang Beach needs to be managed in a balanced manner with a conservation approach and beach ecotourism to ensure the sustainability and sustainability of nesting habitats for various types of turtles.

Efektivitas Bioakumulator Tanaman Hydrilla verticillatapadaCemaran Tanah pada Budi Daya Padi Genangan
Get PDFSoil pollution can occur due to agricultural waste, one of which is the excessive use of pesticides. Contaminants that are often found are heavy metal of copper (Cu). Rice plants will absorb and store heavy metal elements in polluted soil and waters, and these heavy metals will undergo a process of bioaccumulation in plants that affect plant growth. Efforts to deal with heavy metal contaminants have been carried out. In its application, plants such as hydrilla plant (Hydrilla verticillata) can be used to reduce pollution in the environment. This study aims to determine the effectiveness of using hydrilla plants in reducing heavy metal pollutant copper in flooded rice cultivation. This research was conducted from May-November 2022 at the Agrotechnology Greenhouse, and for laboratory testing it was carried out at the CDAST Laboratory, University of Jember. This research was conducted using a completely randomized design consisting of one factor with four replications. Giving hydrilla did not significantly affect the morphology of rice plants but had a significant effect on the increasing levels of chlorophyll. The concentration of copper in rice plants decreased after treatment with hydrilla plants compared to negative controls without hydrilla plants. In this study, it can be concluded that the use of hydrilla was able to reduce the levels of copper metal present in rice plants and did not affect the growth of rice plants morphologically.
