Potensi Formulasi Bioenkapsulasi Bacillus Sp. Terhadap Penyakit Layu Bakteri Pada Tanaman Cabai Rawit
Full text linkCayenne pepper production in Indonesia in 2021 decreased by 8.09% which was caused by many factors, one of which was disease. Bacterial wilt is one of the important diseases of cayenne pepper plants which has caused many losses to farmers. The control carried out by farmers is synthetic chemical pesticides used by farmers to overcome bacterial wilt disease, but this has a negative impact on the ecosystem. As an alternative, biological control uses biological agents such as Bacillus sp, which need to be formulated so that they can effectively inhibit bacterial wilt disease. Bioencapsulation formulations using sodium alginate and extrusion techniques are considered more stable and efficient than liquid formulations. This study used a factorial completely randomized design (CRD) using control factors. The first factor (K) is the concentration of sodium alginate used, K1 = 1% concentration; K2 = Concentration 1.5%; K3 = 2% concentration. The second factor (W) is the application time of the beads, W1 = coincides with transplanting; W2 = 7 days before transplanting. Each treatment was repeated 3 times. Observation of the beads showed that there were colonies of Bacillus sp. on the surface of the beads. The encapsulation efficiency (EE) results show that K3 treatment is the treatment with the highest value. The K2 treatment showed the lowest rate of change in bead diameter, namely 0.15 mm/week. The K2 and K3 treatments were treatments that were able to achieve the highest viability of 106 CFU/ml during the storage period. The K2W1 treatment was the best treatment in inhibiting bacterial wilt disease with a disease intensity of 55.5% and an inhibitory effectiveness of 44.5%. The K3W1 treatment was the best treatment in stimulating plant growth with a plant height of 16.3 cm, root length of 10.3 cm, and root wet weight of 0.56 grams
A Practice and Development of Making Carrageenan Beads with Interphase and Non-Interphase Methods
No full text<p><span>Microencapsulation is a technology that can adsorb substances into the form of beads, with one of the objectives being to facilitate application. There are many kinds of bead-forming materials, one of which is carrageenan. Carrageenan is a polymer derived from seaweed and used extensively in industry. This paper aims to practice and show the differences in producing carrageenan beads with interphase and non-interphase methods. In general, the procedures for the interphase and non-interphase methods are the same, but in the interphase method, vegetable oil is added to form the interphase. The interphase method forms carrageenan beads with perfect spherical shapes, while the non-interphase method forms carrageenan beads with random shapes.</span></p>

EVALUATING THE LONG-TERM STORAGE TIME VIABILITY AND SIZE DYNAMICS OF BACILLUS SP. BIOENCAPSULATION IN SODIUM ALGINATE MATRIX
Full text linkThe use of biological agents such as Bacillus sp. bacteria has begun to be widely used by farmers as a new form of control. Bacillus sp. needs to require special methods in its application because it has certain living conditions, and Bacillus sp. is vulnerable to environmental pressures. Bioencapsulated formulation in the form of granules is considered effective as a form of bacterial application in soil because it is able to protect Bacillus sp. and maintain survival. This study aims to determine the best concentration of sodium alginate in maintaining the viability of Bacillus sp. at the in vitro stage and to see changes in the size of the beads. The beads were made using extrusion method by combining Bacillus sp. suspension and sodium alginate suspension at 1%, 1.5%, and 2% concentration. The concentration of sodium alginate was not a major factor in changes in bead size and viability test results experienced significant changes in each observation. 1.5% and 2% concentrations can reach the highest viability value of 3x106 CFU/mL and decreased during 1 month of observation. Changes in bead size and viability were caused by the alginase enzyme produced by Bacillus sp

Utilization of Organic Waste as Sustainable Electrical Bioenergy with Microbial Fuel Cell Method
No full textThe problem of organic waste is not new in the world, but so far organic waste
management has only become fertilizer. Organic waste is solid waste that is easy
to rot and causes a very strong odor, so it requires new management innovations.
The use of electrical energy sourced from non-renewable and unsustainable
materials can cause environmental problems such as air pollution, noise pollution,
and waste pollution. The two problems that occur in Indonesia that both cause a
lot of disadvantages, especially in the environment, can be turned into a benefit
that will help overcome the problem, namely by utilizing microbial fuel cell
technology. The manufacture of Microbial fuel cells with the main substrate in the
form of organic waste has the aim of solving environmental problems due to
organic waste and non-renewable and unsustainable sources of electrical energy.
Microbial fuel cells have four main components, namely substrate, anode, proton
exchange membrane, and cathode. The working principle of the microbial fuel cell
is to take advantage of bacterial interactions that occur in organic waste and the
results of interactions in the form of chemical energy are converted into electrical
energy. The electrical energy generated by microbial fuel cells can solve the
problem of electrical energy sources and organic waste. Microbial fuel cells in the
future are expected to be able to become an alternative energy source that is
environmentally friendly and sustainable. Low electrical power as well as the
selection of the right organic waste substrate are challenges in developmen
Konstruksi Budaya Pada Komunitas One Piece Tangerang Selatan
No full text<p><em><span>This thesis examines Japanese culture as popular culture which can be a factor in the construction of identity among fans of Japanese culture within the One Piece community, South Tangerang. This thesis aims to identify how Japanese culture can be one of the triggering factors for someone to use his identity as a fan in his daily life by showing a lifestyle that is different from his environment. This thesis uses qualitative methods with data collection techniques of observation, interviews, and in-depth observations of five informants. The concept used to analyze this thesis is Cultural Identity in the perspective of Cultural studies from Hall Stuart and Cris Barker. In the view of cultural studies, cultural identity explains how individuals construct identities beyond their original identities by using signs and symbols. The conclusion of this thesis is that Japanese fan culture can unknowingly enter and become the dominant culture in an individual when the individual starts consuming it. The representations made by fans are different for each fan. This is due to the difference in interpreting the existing symbols. Like, wearing Japanese-themed clothes, interacting with Japanese, using attributes (key chains or pins), and even drawing manga characters. because cultural identity has a dynamic nature that makes cultural identity diverse and developing. An example is a fan who continued to draw manga and eventually he was able to make his own Anime series, which gave rise to a Cultural Imperialism</span></em></p>
