Abstract

The purpose of this study was to analyze anatomical characteristics, fiber morphology, and several important physical properties of nyatoh (Palaquium lanceolatum), pisang putih (Sindora walichii), and sepetir (Mezzettia leptopoda) wood from North Kalimantan in order to support the proper utilization of each wood species. All parameters were analyzed using their standard procedures. Results showed that anatomical characteristics of nyatoh wood are the vessels predominantly are in radial multiples and contained tyloses, ray parenchyma is mostly uniseriate and even, while axial parenchyma is in narrow tangential line with irregularly spaced. For pisang putih wood, the vessels are exclusively solitary, ray parenchyma of two distinct sizes, while axial parenchyma are in continuous tangential bands with irregularly spaced. In case of sepetir wood, the vessel is in radial and diagonal patterns, rays tend to have two different sizes, axial parenchyma is vasicentric to aliform, and has the axial resin canals in continuous tangential bands. Average values of fiber length and fiber wall thickness are 1904 and 3.61 µm (nyatoh), 1708 and 4.51 µm (pisang putih), and 1337 and 3.39 µm (sepetir), respectively; while the mean values of specific gravity and T/R-ratio are 0.42 and 1.41 (nyatoh), 0.37 and 2.34 (pisang putih), and 0.32 and 1.40 (sepetir), respectively. Nyatoh wood is categorized as the Strength Class of III, while pisang putih and sepetir woods are categorized as the Strength Class of IV. Compared to pisang putih and sepetir woods, nyatoh wood is more potential for pulp, paper, and furniture manufacturing.

Abstract

Overfishing can occur in open access fisheries, where fishermen conduct fishing activities without restrictions. Fisheries management based on biological factors alone (Maximum Sustainable Yield approach) is considered inadequate because it does not consider socio-economic aspects in fisheries management. The study aims to analyze the utilization of small-scale fishery resources in Semarang City and determine its policies to be sustainable. Bioeconomic analysis was used to optimize the utilization of fishery resources. Small-scale fisheries management strategic policies, used analysis of Interpretative Structural Modeling (ISM). The results showed utilization of small scale fishery resources in Semarang City can be achieved with optimal production of anchovy (Stolephorus spp.) 1,477.79 tons/year and optimal effort of 324 units; optimal production of Tembang (Sardinella fimbriata) 235.96 tons/year and optimal effort of 516 units; optimal production of mackerel (Rastrelliger kanagurta) 28.51 tons/year and optimal effort of 479 units; and optimal production of Petek (Leiognathus sp.) 25.54 tons/year and optimal effort of 847 units. In conclusion, the Anchovy (Stolephorus spp.) resources have experienced overfishing since 2007-2008; Mackerel (Rastrelliger kanagurta) resources overfishing occurred from 2009-2015; and Petek (Leiognathus sp.) resources have experienced overfishing since 2014-2016; while Tembang (Sardinella fimbriata) resources have not experienced overfishing because they are not the main target. The key sub-elements of small-scale fisheries management in Semarang City include: a) fishermen; b) Semarang City Fisheries Agency; c) overcapacity; d) decreasing catches; e) environmentally unfriendly arrests; f) ineffective regulation; g) conservation fish resources; h) increasing fishermen's income; i) limitation environmentally unfriendly fishing gear.

Abstract

Iron-fortified rice potentially increases iron consumption in order to overcome anemia in Indonesia. Premix kernel can be applied as a fortificant vehicle being formulated into rice. The premix kernel is processed by mixing rice flour and iron source and extruded to yield rice-like extrudate. This research aimed to develop iron premix kernel using a double screw extruder and evaluate the fortificant homogeneity during mixing and stability due to washing as well as overall sensory acceptability of fortified rice. The premix kernel was made by mixing rice flour (1000 g), pyrophosphate ferries (containing 5,000 mg Fe), and GMS (10 g) for 5, 10, 15, 20, 25, and 30 minutes, added with water (450 mL) and passed into an extruder at 80°C. The dry-mixed for 20 minutes yielded a homogenous premix kernel (6,030±135 mg/kg with RSD of 2.25%). The mixing of premix kernel and Pandanwangi rice (1:100) for 25 minutes using a blade mixer yielded fortified rice with iron content of 39 mg/kg and RSD of 13.56%. The washing process of fortified rice decreased iron content, and the percentage of iron loss was affected by the washing frequency. Raw and cooked fortified rice did not differ organoleptically from those without fortification. Keywords: anemia, fortified rice, ferric pyrophospate, homogeneity, premix kernel

Abstract

Bamboo is known as fast-growing species that could be derived into various products. However, bamboo is suspectible to the wood destroying organisms. Preservation is one way to improve the service life of bamboo. This study aimed to analyze the effect of differences in anatomical structures of betung bamboo (Dendrocalamus asper Backer) and andong bamboo (Gigantochloa pseudoarundinaceae (Steudel) Widjaja), and the effect of pressure on the flow time and retention of entiblu preservative in the Boucherie method. Bamboo stems with diameters of 10-14 cm were cut in 1; 1,5; 2; and 2,5 m lengths. The bamboo stems with moisture content of around 30% were preserved by 5% of entiblu preservative solution. The data observed were the flow time of the preservative entiblu solution from base of the stem until dripping on the top of the bamboo culm, and the retention of preservative. The anatomical structure of the bamboo trunk before preserving was also observed. The results showed that the average flow times in andong bamboo and betung bamboo were 37.75 minutes and 41.50 minutes, respectively. The average retention of entiblu solution on andong bamboo was 3.49 kg/m³ and on betung bamboo was 3.60 kg/m³. Keywords: andong bamboo, betung bamboo, anatomical structure, boucherie method, entiblu preservative

Abstract

Sand sea cucumber (Holothuria scabra) is an aquatic product that belongs to Echinodermata, a habitant in almost all Indonesian seas. The main component of the sea cucumber is protein, one of which is collagen. This study aimed to extract and characterize collagen from the species using the acid-base extraction method. The characterization of sea cucumber collagen includes molecular weight, amino acid components, Fourier transform infrared spectrophotometry, and scanning electron microscopy analysis. This study has successfully extracted collagen from the sample using an extraction system: NaOH 0.1 M; CH3COOH 0.1 M; and distilled water under 45°C treatments, gave 6% yield. The collagen has a molecular weight 110-130 kDa. Based on the infrared spectra, the specific functional groups of the collagen are amide A (3379.29 cm-1), amide B (2924.09 cm-1), amide I (1681.93 cm-1), amide II (1560.41 cm-1), and amide III (1249.87 cm-1). The collagen falls into type I. We suggest an alternative resource of collagen from sand sea cucumber, other than poultry and mammals. Keywords: characterization, collagen, extraction, fishery, sand sea cucumber

Abstract

In supporting the replacement of potato varieties with the varieties that are adaptive to drought, effective and fast methods are needed. One of which is through in vitro screening of drought-tolerant genotypes. The aims of this research were to determine the appropriate concentration of sorbitol as a critical limit in the in vitro screening process of drought-tolerant genotypes, as well as to determine vegetative characteristics that could be used as indicators of in vitro selection and also to obtain in vitro drought-tolerant genotypes. To achieve these objectives, we used single-nodal explants of seven genotypes cultured for six weeks on MS media added with four levels of sorbitol concentration. Of the four treatments, sorbitol level that could distinguish susceptible and tolerant plants was 0.2 M sorbitol and at this concentration, the characteristics that showed significant interactions were plant height and root length, so that both characteristics could be used as selection indicators for the analysis of tolerance tests for the seven genotypes. The results of tolerance test using the analysis of relative decline and stress-susceptibility index (SSI) showed that PKHT4 and PKHT6 were the genotypes that were tolerant in vitro. Keywords: drought tolerant, in vitro, Solanum tuberosum, sorbitol

Abstract

People’s lifestyles nowdays tend to want healthy-practical food that is strongly supported by a healthy diet. Cassava as whole food is considered as a healthy food and has the potential to become rice substitute but needs an appropriate technology to facilitate food serving. In this research, ready-to-eat cassava products then called "cassava chunk" were made by applying canning technology using retort pouch packaging. The achieved value of the heat adequacy (F0) is very important in the canning process to ensure food safety. Therefore, this study aimed to produce cassava chunk product as a whole food, optimize the size and amount of brine in the sterilization process, determine the F0 value after blanching and non-blanching treatments, as well as to analyze the chemical characteristics of fresh cassava and cassava chunk. The sterilization was done by using a pressure cooker with a specially designed basket using hermetic retort pouch packaging. The initial characterizations showed that fresh cassava had a pH of 6.70 and 0.9 aw at 24.6°C. The addition of 20% (b/v) 1% brine solution in the sterilization process with 3 x 2.5 cm cassava chunk was the most preferred by the panelists. The sterilization process with blanching treatment before being packaged reached an F0 of 3.43 minutes, which was safe to consume, and with non-blanching treatment before being packaged reached an F0 of 2.73 minutes. The proximate analysis of cassava chunk showed an increase in the water content from 60.89% to 68.44%, the starch content increased from 74.43% to 80.41%, the soluble dietary fiber decreased from 6.78% to 3.34%, but the fat content decreased from 1.54% to 0.65%. Meanwhile, ash, protein, and insoluble dietary fiber did not show any significant differences after the sterilization. Sterilization technology could produce ready-to-eat cassava chunk as a whole food and was acceptable by 45 organoleptic panelists. Keywords: cassava chunk, whole food, proximate analysis, F0
