Abstract

Spent Bleaching Earth (SBE) is a by-product of the refining of Crude Palm Oil (CPO) into cooking oil which is classified as hazardous and toxic materials waste. SBE has the potential to be used as a filler in the production of NPK fertilizer. This study aims to compare the effect of SBE and Deoiled Bleaching Earth (DBE) as the replacement of clay mineral, which is expected to have the same effect as the control treatment in terms of the leaf area, total dry weight, plant height and yield of plant. This experiment used a one-factor Randomized Complete Block Design (RCBD) with three replicates. The treatments of filler in NPK fertilizer were 10% clay minerals, NPK with 5% clay mineral + 5% SBE filler and NPK with 5% clay mineral + 5% DBE filler. Fertilizer was given twice, ie when the plant was 14 days after planting (DAP) as much as 2 g polybag-1 and age 35 DAP as much as 3 g polybag-1 at each treatment. The results showed that the application of NPK fertilization with 5% clay mineral + 5% SBE filler and NPK fertilization with 5% clay mineral + 5% DBE filler had the same effect as NPK fertilization with 10% clay mineral filler on leaf area, total dry weight, plant height and yield of plant. SBE and DBE can be used as substituties for clay mineral in NPK fertilizer production.

Abstract

Indonesian Citrus and Subtropical Fruits Research Institute (ICSFRI) has generated a technology of Bujangseta (bearing fruits throughout the year) to increase citrus plant productivity and to support the sustainable availability of citrus fruits in the market. This study aims to identify the characteristics of Bujangseta technological innovation that might influence the adoption of the technology by farmers. The study was conducted in Banyuwangi Regency in November 2019 by using a census method to all 16 cooperator farmers of Bujangseta technology. This present study applied a descriptive analysis method based on the scoring and category of technological innovation characteristics. The results showed that the innovation characteristics of Bujangseta technology were: 1) it was very profitable since tangerine farming with the application of Bujangseta technology generated higher income than that without the application, 2) it was greatly appropriate with the local conditions as all production supplies were locally available, 3) it was easy to be applied because farmers did not suffer any complication to employ Bujangseta practice, 4) it was easily observed since the results of Bujangseta implementation were easy to be observed visually by farmers and 5) it was easily trial-tested as the method of Bujangseta was easy to try and apply. Therefore, this new technology had a very high adoption opportunity rate, showing that the technology had a great chance of being adopted by farmers.

Abstract

The fluctuation of coffee export from North Sumatra to the three primary destination countries, including the United States, Malaysia and Japan, has never been reported simultaneously. The research was aimed to analyze the factors affecting the volume of coffee export from North Sumatra to the United States, Malaysia and Japan. The research was conducted in November 2019 until March 2020. This study employed secondary data, which were obtained from the Statistics of Sumatera Utara, International Coffee Organization, Bank Indonesia and Trading Economics in the time series of 34 years (1986 until 2019). The data were analyzed using the quantitative descriptive method with the panel data regression analysis by applying the Chow and Hausman tests with the Eviews 10 software. The analysis results show that the Free on Board (FOB) value, Indonesia Coffee Prices (ICP), Rupiah Exchange Rate (RER), Gross Domestik Product (GDP) per capita and coffee yield simultaneously and significantly affected the Coffee Export Volume (CEV) from North Sumatra to the United States, Malaysia and Japan. The FOB value, ICP and coffee yield had a partially significant positive effect on the CEV from North Sumatra to the three countries. The GDP per capita had a partially significant negative effect, while the RER did not put significant effect on the CEV. The FOB value, ICP and coffee yield are necessary to be increased for maintaining and supporting a rise in the volume of coffee export from North Sumatra.

Abstract

Some of the major problems in cashew marketing performance are low production, inefficient marketing system and low income received by farmers. In addition, farmer with a low bargaining position will only receive prices from market players in the midst of increasing demand and competition in the market. The aim of this study is to examine the behavior and performance of the cashew market in South Buton Regency, Indonesia. Furthermore, the marketing channels, margins, costs and benefits received by each agency were used to analyze the technical and economic efficiency. In addition, random and snowball sampling techniques were applied to determine the farmers and traders, respectively. The results showed that the behavior of market price was based on the cost analysis, supply and demand, as well as the expected benefit. Meanwhile, the transactions were made partially (initial payment before and after the products were sold) and some in cash. The market players were unique in providing cooperate capital to farmers. Moreover, the market performance shows an efficient system from the two channel patterns formed, close distance indicates a technically efficient system and low marketing cost indicates economic efficiency.

Abstract

Strawberry is a popular and nutritious fruit. However, its improper post-harvest handling leads to quality degradation. The aim of this study was to investigate the effects of active paper packaging placements methods on strawberry (Fragaria x ananassa) quality during refrigerated storage. Strawberry quality was determined based on the physical (weight loss, hardness, color), chemical (pH, total titratable acid, total soluble solids and vitamin C content) and microbiological (total plate count) properties. The results of this study indicated that different placement methods of active paper packaging had no significant effect on the physical and chemical qualities; but it did affect the microbiological quality of the strawberries. At the end of the experiment (12 days), the microbial content of C (the bottom and walls), D (covering all surfaces) and E (cut into pieces) samples were significantly lower than the A (without active paper packaging) and B (the bottom) samples. The Total Plate Count (TPC) values of the control and B samples were higher than the maximum acceptable limit of 6 log10 colony-forming units (CFU) g-1, while the other samples remained below the limit. These results indicated that a larger surface area of active paper that had contact with the strawberries provided better protection against microbes. Due to their microbial properties, C, D and E treatments maintained the strawberry quality for up to 12 days, compared with 9 days for control and B treatments. Active paper packaging containing oleoresin from solid waste of pressed Curcuma xanthorrhiza Roxb. can be applied to extend the shelf life of strawberries during refrigerated storage.

Abstract

Raja Bulu is one of the banana varieties favored by the community because of its thick fruit flesh and sweet taste. However, its parthenocarpic characteristic and vegetative propagation make this banana variety has limited genetic variation. Attempt to improve the genetic variation was conducted through induced mutation breeding using gamma-ray mutagens. This research aimed to select M1V1 generation of Raja Bulu banana (Musa paradisiaca Linn.) obtained by gamma rays’ irradiation for their growth traits which are expected to produce banana varieties that have an early maturity and high yield. This study used a randomized complete block design without replication by observing the generative growth of each individual of Raja Bulu banana irradiated by gamma rays and without radiation as a control. The results showed that gamma-ray irradiation treatment caused Raja Bulu banana to be harvested earlier and produced higher fruit weight than controls. The gamma-ray irradiation had a random influence on Raja Bulu bananas. The 10 Gy gamma-ray irradiation dosage influenced the morphological diversity in the generative phase of Raja Bulu banana. The treatment of gamma irradiation resulted in 5 individual plants that flowered and matured earlier as compared to controls.

Abstract

Potential food resources can be utilized through food diversification as a part of the government's efforts to minimize socio-economic inequality with sustainable food security development program. The purpose of this study was to observe the role of food diversification in reducing social inequality through sustainable food security development. This study uses descriptive qualitative methods with secondary data collection techniques which include data references as well as documentation related to food security development. The results showed that in Indonesia, food diversification program has an impact on increasing income, household resilience and welfare with a decrease in the number of the rural poor population of 4.7% (from 16.31 people to 15.54 people). It was positively correlated with the increase in farmers' income by (IDR) 30.37 million per capita increase (4.47%). Then, followed by the level of food security in the district area reached 80.53% (335 regions) and for urban areas amounted to 92.85% (91 regions). National food security can be achieved through maximizing the potential use of food resources at the regional level, by diversifying food based on local wisdom and optimally local resources. It can be concluded that food diversification is a policy that can be used by the government to increase community economic income and reduce poverty and social inequality.
