Authors: Wahyudi D , Noor E , Setyaningsih D , Djatna T , Irmansyah  
Published: June 2020

Abstract
Citronella oil is one of the essential oils derived from the leaves and stem of lemongrass (Cymbopogon nardus). At present, most of the lemongrass oil industry in Indonesia is still in the form of upstream industries which only provide crude purified oils with low purity for export with a fairly low sales value. Technology in improving the purity of citronella oil needs innovation in following the development of the industrial revolution 4.0. This article presents an overview of the research opportunities in the development of distillation for fractionating citronella oil referring to automation of optimization processes in the vacuum fractional distillation accompanied by inspection of the quality of essential oil isolation run in the line process based on smart sensors integrated in a computer program. The combination technique of quality control of essential oils in line process system combined with the optimization technique of the vacuum fractional distillation process has not been studied by advanced researchers. Therefore, this study has a state of the art process engineering and smart sensor-based quality control systems that can be developed for strengthening the Indonesian citronella oil industry.

Published: June 2020

Abstract
Colostrum is the first fluid produced from the mammary gland 24 to 72 hours after the postpartum. Here, we have the psychochemical characteristics of fermented colostrum that fermented with kefir grain for 24 and 48 hours and its activity against eight foodborne pathogens. Bacillus cereus, Bacillus pumilus, Staphylococcus aureus, Listeria monocytogenes, Escherichia coli, Salmonella Typhi, Pseudomonas aeruginosa, and Klebsiella pneumoniae were used as test strains, and antibacterial activity was investigated based on inhibitory zones using disc diffusion methods. Psychochemical characteristics and activity varied according to colostrum kefir type and fermentation time. The widest and the strongest antimicrobial activity is obtained after at least 48 hours of fermentation for all colostrum kefir, although the traditional kefir fermentation method is for 18-24 hours at 25 °C. For the type of colostrum kefir K1, K2, P1, and P2 after fermentation for 48 h, it shows that antimicrobial activity increase along with the increasing of titrable acidity and decrease in pH value.

Abstract
The best strategy is intensively required for small industries in Indonesia nowadays, especially in Aceh. Rimbun Corp, as the oldest chocolate company in Aceh, still has many problems with expanding the production of Socolatte (local chocolate bar brand). The product has become unfamiliar for the tourists in Aceh recently. Moreover, this product has a short shelf life and lower quality if being stocked in an extended period. As a result, this chocolate cannot be sent further from the store, and it is more challenging for the customer to buy the product. The purposes of the research are to identify the main problems and to choose the best strategy using Business Model Canvas (BMC) as a method to collect the current data and to determine the specific problem in the whole production process. The research finds that there are no action in the company to maintain customer relationship, and the main key activities should be priorities for finding a solution. After testing through the Analytical Hierarchy Process (AHP), the crucial criteria for expanding the small industry is the raw material (0,4453). Moreover, the industry should adopt new technology (0,3632) for creating an advanced chocolate product from bean to bar so the company can sell them globally and profitably.

Published: June 2020

Abstract
Online shopping nowadays is one of the most popular ways to make transactions. Customer transactions recorded on the online shopping application can be used by a retail company’s Customer Relationship Management (CRM) manager to make sales strategies and increase customer loyalty. Sales strategies are needed to identify products that will be of interest in the market as well as potential customers who will be interested in products. The implementation of skyline queries produces the most interesting and preferred set of products. Whereas to search for the potential set of customers who are interested in certain products, a reverse skyline query can be used. To find a larger set of customers, a reverse k-skyband query can be implemented. Reverse k-skyband queries can also be applied to determine the level of interest of each customer in each product in the product bundling strategy. Product bundling is a sale of two or more products in one package commonly used by CRM manager to increase customer loyalty. This research proposes reverse k-skyband query to find the most potential customers who like bundling products. This study evaluates the performance of the reverse kskyband query in terms of computation time.

Authors: Sujianto  , Ermiati  , Wahyudi A 
Published: June 2020

Abstract
Institutional clove farmers are still very weak, both in terms of marketing and in a pest control system. The number of damaged plants affected decreases production and productivity. Hence, the farmers’ revenue was lowering and they lost their income. This study aims to analyze the existing institutions in clove production centers and to formulate strategies to strengthen institutional pest control of clove. The survey was conducted in April-October in Sumedang and Sukabumi Regencies in West Java. The results show that there were three institutional models, namely Temu Urip at Sumedang, Maju Bersama, and Tanijaya groups at Sukabumi. All models had only focused on cooperation activities such as land clearing, plant cultivation process, weeding, harvesting, and savings-loans. The model that was specific to the pest control had not been developed. To establish and strengthen their position, farmers should innovate the concept of the Clove Institutional Model. They should take a partnership with other related elements, such as cooperatives, distributors of pesticides, financial institutions, government, universities, and research institutes. In this model, farmers’ association plays an important role as an institution that controls clove pests mainly at the district level and coordinating down to the village level.

Published: June 2020

Abstract

Ralstonia solanacearum is one of the main pathogens in tomato plants that cause bacterial wilt disease. R. solanacearum in the field is difficult to control, because some phytopathogenic bacterial species produce EPS in large quantities. The practices of cultivation, soil fumigation and development of resistant varieties have been carried out as an effort to control these pathogens. Therefore, biological control is another alternative in controlling this pathogen. The research was conducted at the Plant Bacteriology Laboratory and in the Greenhouse of the Plant Protection Department, Faculty of Agriculture, Gadjah Mada University, Yogyakarta. In this study, the bacteria Pseudomonas putida strain Pf-20 and Streptomyces spp (isolates S-4 and S-16), 9 varieties of tomatoes and R. solanacearum were used. This study uses a Completely Randomized Design consisting of 3 treatments of biological control bacteria and 3 replications. The parameters observed were incubation time and disease intensity. Then also calculated the rate of disease progression and the value of the Area Under Disease Progress Curve (AUDPC). Data obtained were analyzed descriptively for all parameters ecxept incubation time was analyzed statistically. Statistical analysis data were then further tested with LSD at 5% level. Based on the results, the application of antagonistic bacteria can suppress the development of bacterial wilt disease. The best suppression of bacterial wilt disease development by biological control agents was seen in amelia and tombatu varieties. Further research is needed to observe the relationship between varieties and the ability of antagonistic bacteria to control R. solanacearum in tomato plants.

Abstract
The G1/01 mutant line is a chili pepper variant resulting from a mutation with Ethyl Methane Sulfonate to the genotype 1 (G1) which is a descendant of a commercial chili pepper varieties Cakra Hijau. In this study the G1/01 line was compared with Capsicum frutescens varieties, Cakra Hijau and Genie and large chili Capsicum annum (CAT2) based on morphology, physiology (capsaicin content) and molecular, Random Amplified Polymorphic DNA (RAPD). The results showed that G1/01 had a similar morphology to the varieties of Cakra Hijau, Genie and CAT2 based on habitus, branching, plant height, flower shape and fruit shape, but G1/01 had greater leaf length and width than the Cakra Hijau, Genie and CAT2 and larger fruit size than the Cakra Hijau and Genie. When compared with CAT2, G1/01 has a shorter fruit size even though its diameter was almost the same. The four types of are included in the spicy and very spicy categories. The fruit of G1/01 line showed a change in the level of spiciness from the spicy category when young to the very spicy category when the fruit was ripe red. The RAPD results showed that the Cakra Hijau and Genie varieties were similar to each other while the G1/01 mutant was different from the two. CAT2 shows quite a distance with the other three types. Dendrogram based on morphological, physiological and molecular data shows that G1/01 changes quite large from the Cakra Hijau, but does not similar as CAT2.

Abstract
This research aimed to improve the quality of cassava starch edible film by addition of gelatin or modified cassava starch. Modified cassava starch was obtained by precipitation of gelatinised cassava starch. First experiment was carried out using a completely randomized design (CRD) with six treatments of addition of gelatin (0%, 1%, 1.5%, 2%, 2.5% and 3% (w/w). Second experiment was carried out by using the addition of modified cassava starch (15% w/w). The results showed that the addition of 3% gelatin produced edible film with highest compressive strength but did not improve its water vapour transmission rate (WVTR). WVTR of cassava starch edible film, however, can be improved by using 15% modified cassava starch.

Authors: Marni H , Fahmy K , Hasan A , Ifmalinda  
Published: June 2020

Abstract
A Michaelis-Menten equation was proposed for predicting the respiration rate of chili as a function of O2 concentration at 15°C. The respiration rate as O2 consumption and CO2 production were measured using the flow-through system method. The low oxygen limit of chili was also determined by the respiratory quotient. Chili was stored at 15°C at various O2 concentration. Using of Michaelis-Menten type respiration model provided an excellent prediction to examine the behavior of the respiration rate of chili at any O2 concentration. The lower O2 limit obtained in this study could be used to estimate the optimum condition in Modified Atmosphere Packaging (MAP) of chili.
