Published: April 2022

Abstract
Sangkuriang catfish (Clarias gariepinus var) is a freshwater commodity fish that has the potential to be developed. Sangkuriang catfish farming activities still often experience problems in their implementation, especially water quality problems in the form of a buildup of organic matter that does not decompose and causes poison to catfish. The determining factor of success in growing heterotrophic bacteria in aquaculture waters is the ratio of C/N in the tank of sangkuring catfish. This study aims to determine the C/N ratio, growth rate, and survival of catfish. The results showed that the addition of a C/N ratio of 10:1 has an effect on the growth, survival rate of catfish and can reduce the ammonia content in catfish culture media.

Published: April 2022

Abstract
The main disease in cocoa pods is fruit rot caused by the fungi Phytophthora palmivora. The loss caused by P. palmivora is almost 90%. Currently, the control is still using synthetic fungicides which are harmful to humans and the environment. Therefore, the use of essential oils as fungicides is a safe control for the environment. This study aims to obtain a combination of nutmeg, cloves, and citronella that are effective as a botanical fungicide to control cocoa pod rot disease. The study was conducted at the Lampung State Polytechnic Plant Laboratory using a completely randomized design with 8 treatments which were repeated 5 times. The treatments tested were (1) negative control (water), (2) positive control (synthetic fungicide), (3) nutmeg oil, (4) clove oil, (5) citronella oil, (6) nutmeg + clove oil, (7) nutmeg oil + citronella, and (8) Clove and citronella oil. Essential oil testing on the growth of P. palmivora was carried out in vitro by inoculating agar pieces containing fungal culture on the surface of PDA containing essential oils. The results showed that all essential oil combination treatments were able to suppress the growth of the P. palmivora on PDA media. The combination of nutmeg oil and clove oil can suppress fungal growth by 77%, while the combination of nutmeg oil and citronella oil reaches 56.5% and the combination of clove oil and citronella oil reaches 27%. However, the single treatment that best suppressed the growth of P. palmivora was citronella oil, which was 32.8%.

Abstract
Abstract As one of the commodities supporting food security is underdeveloped due to marketing problems. Fluctuating supply and prices of organic rice, weak market information, high transportation costs, organic product certification, and limited capital become the basis for the need for analysis strategy for developing an organic rice market. The purpose of this study are: (1) identify the internal and external environmental factors, (2) formulate the best alternative strategy for the development of the organic rice market in South Lampung Regency. The research was carried out in Candipuro sub-district, based on being a center for organic rice production in South Lampung Regency. The data were analyzed qualitative and quantitative using descriptive analysis, identification of Strengths, Weaknesses, Opportunities, and Threats using IFE and EFE matrices, to obtain alternative strategies using the IE matrix and SWOT matrix. The results of the analysis show that the main weakness of the organic rice farmer group is the low performance of human resources and the limited number and types of organic products that cause a lack of market share for organic rice. The result of the IE matrix shows that the Mitra Organic Farmer Group is in the position Diversification. This policy needs to be implemented in preparation for broad diversification into various types of business activities that provide opportunities for improving the role of an institution or institution (conglomerate diversification strategy). Alternative strategies formulated based on the SWOT matrix are (1) increasing the number and types of organic products produced/product diversification, and (2) increasing institutional capacity to become cooperatives to optimize the government’s role in market accessibility and funding.

Published: April 2022

AbstractThe problem of fish feed in Indonesia is currently dominated by import dependence on feed raw materials, especially fish meal and soybean meal. One alternative that currently can be chosen is indigofera leaves (Indigofera zollingeriana).The indigofera leaves used are indigofera leaves that have been cultivated by farmers in Kemiling District, Bandar Lampung City. Harvest is done at the age of 12 months. After harvesting, indigofera leaves are dried in the sun and the flouring process is carried out. Furthermore, indigofera and indigofera leaves were tested proximately and compared with commercial indigofera flour. In addition, the resulting indigofera leaf flour was hydrolyzed with cellulose enzyme at a dose of 10 g/kg for 5 days and a proximate test was carried out afterwards. The results showed leaf protein content of 19.95%, protein content of treated indigofera leaves flour 29.74% while protein content of commercial indigofera flour was 21.95% (dry weight). Meanwhile, the protein content of indigofera leaves flour which had been hydrolyzed with cellulose enzyme at a dose of 10 g/kg for 5 days increased to 31.30% and crude fiber decreased from 28.75% to 1.98%. The conclusion of this study is that the resulting indigofera leaves flour has the lowest crude fiber content and higher protein than indigofera leaves flour without hydrolysis of cellulose enzymes and commercial indigofera flour. Indigofera leaves flour hydrolyzed with cellulose enzymes resulted in a decrease in crude fiber and an increase in protein.
Isolation of Glucoamylase from Aspergillus Niger to Produce Liquid Sugar from Tapioca Flour
Authors: Rina Oktaf , Agustien Anthoni 
Published: April 2022

Abstract
This study aims to isolate the glucoamylase enzyme from Aspergillus niger to produce liquid sugar from tapioca flour. Enzymes are produced in a batch system laboratory-scale bioreactor. The fermentation substrate in an agar medium modified with the addition of starch. Fermentation was carried out for 168 hours at room temperature with an agitation speed of 120 rpm. The manufacture of liquid sugar is done by adding an enzyme as much as 0.3; 0.4; and 0.5 ml while the substrate concentration was varied by 20%; 30%; and 40%. The results showed that A. niger produce extracellular enzymes such as amylase and glucoamylase, particulary at exponential phase and the initial stationary phase. Enzymatic hydrolysis of starch consists of two stages, namely liquification and saccharification. In the liquification process, the enzyme α-amylase is used to break down starch containing amylose and amylopectin into dextrins. Next in the second stage is the saccharification process, where dextrin is hydrolyzed into glucose with the help of the glucoamylase enzyme. Optimal liquid sugar production can be done by adding 0.5 mL of crude enzyme extract at 30% (w/v) tapioca concentration. Further research is recommended to carry out enzyme purification to produce liquid sugar products with higher sugar purity.

Abstract
Efforts to increase the quality of Dendrobium orchids can be made by increasing the genetic quality through crosses while increasing the quantity can be done by propagation through in vitro culture. Information about the compatibility of an orchid species is very important to maximize the acquisition of seeds as propagation material. The seeds from the cross were propagated by in vitro culture technique. The purpose of this study was to obtain a compatible crossing method between crossing and selfing D.Polinela Lampung orchids with selected parents and to determine the effect of giving a combination of media with coconut water concentration in inducing germination and growth of orchid seeds. This study consisted of two experiments, namely (1) the compatibility test of D.Polinela Lampung orchids with three types of Indonesian orchids (D.discolour, D.leporinum, D.lasientera), and (2) the effect of basic media (MS, VW, Growmore, Gandasil) and water concentration CW (0, 50, 150, and 250 ml/1) on seedling growth of D.Polinela Lampung x D.lasientera orchids. In conclusion, among the sixteen crosses of Dendrobium orchids, ten compatibility crosses were found (pollination that produces fruit). The addition of 15 and 25% CW in the growmore medium (91.37% and 98.03%), MS (90.97% and 96.00 %), and Gandasil (90.67% and 92.67%) gave the highest percentage results. Seed germination and protocorm formation. The protocorm that forms the first leaves produced on Growmore media added with 50-150 ml/1 coconut water gave the most results compared to other treatments. The results of the research are expected as basic information in orchid propagation, especially the study of compatibility and germination of orchid seeds.
