Abstract

Fire on peatlands takes place not only in areas where preparation for cultivation is in progress, but also in areas that have been cultivated, such as for sago palm growing. One of the important factors that influence the vulnerability of cultivated peatlands to fire is the availability and amount of biomass fuel that easily catches fire, such as ferns, grasses, and broadleaved shrubs in their living as well as dead (litter) stages. The present study concerns the vulnerability of peatland utilized for sago growing by smallholders, focused in Tebing Tinggi Timur, Kepulauan Meranti District, Riau Province. The objectives of this study were to analyze the composition and assess the biomass of fire catchers in the sago palm plantation. Data collection was conducted in three locations in Kepau Baru Village. In each location, a 1000 m-long transect line was drawn and 10 sampling plots of 2 m x 2 m were established along the line with 100 m intervals. Results showed that total biomass of fire catchers in this growing system was averaged at 24681 kg/ha, in which the dead plant fraction was predominating (average at 17478 kg/ha or 70.81%) over the living plant fraction (in average 7203 kg/ha or 29.19%). The latter consisted of ferns that averaged at 2.191 kg/ha or 30.42%, grasses (20 kg/ha or 0.28%), non-woody broadleaved shrubs (581 kg/ha or 8.07%), and woody broadleaved shrubs (4411 kg/ha or 61.24%). The amount of fire catchers in relatively large quantities in this plantation system could magnify fire risk during drier months, especially during El-nino years. Keywords: biomass, fire risk, grasses, non-woody broadleaved shrubs, woody broadleaved shrubs

Abstract

WINS" (Win-Win Strategy) in the management of protected areas is the strategy that benefit both parties. Agroforestry with forest trees accompanied by agricultural crops may benefits the community if it is implemented in line with the management of Meru Betiri National Park (TNMB) policies. The agroforestry plants proposed in this study were aren (Arenga pinnata), java chili (Piper retrofractum), and porang (Amorphophallus muelleri). This study recommends four strategies for better agroforestry practice in TNMB, i.e.,g. 1) strategy I, increasing public awareness of the urgency of the preservation of national park areas; 2) strategy II, formulating policies to support agroforestry as a strategic management effort; 3) strategy III, education and counseling, as a strengthening of the role of extension workers; and 4) strategy IV, facilitating access to relevant data across all participating institutions and is supported in a multidisciplinary manner. This model may be used as a reference for agroforestry models in conservation areas, especially in TNMB, which will optimize the development of native plants in an area. Keywords: agroforestry, Arenga pinnata, Meru Betiri National Park, SWOT analysis, win-win strategy

Abstract

This study was conducted to determine the physiological response of acute heat stress in Kampung Unggul Balitbangtan (KUB) and Walik chickens with four different HSP70 gene haplotypes (H1', H1, H2, and H3). Acute heat stress is carried out at 35°C for one hour. The data was analyzed based on rectal temperature measurements, distribution of body surface temperature (head, neck, body, and leg area), hormone levels (corticosterone and triiodothyronine), and time of panting. Body surface temperature is detected using infrared thermography. The results showed that haplotype H1 Walik chicken is more susceptible to heat stress based on the rectal temperature. In contrast, H1' haplotype Walik chicken released more heat through the body surface in the leg area. Keywords: heat stress, hormone, KUB chicken, infrared thermography, walik chicken

Abstract

This study assesses the short-term effects of selective cutting on the diversity of ground ants (Hymenoptera: Formicidae) in the secondary rainforest. Ground ants were collected using a pitfall trap in a circular sample plot of 0.5 ha. A total of nine sample plots were randomly placed in a 98-ha cutting compartment. Fifteen pitfall traps were planted in each circular plot. A total of 135 pitfall traps were established in the cutting compartment. The average cutting intensity of 8 trees/haas applied in the cutting compartment. Insect sampling and measurement of environmental factors were carried before cutting and two days after cutting. In this study, the abundance, diversity, species richness, and evenness index of ground ants before cutting compared to after cutting. The results of this study indicated that the short-term impact of selective cutting on ground ants was varied. Selective cutting may increase or decrease the abundance and morphospecies composition of ground ants. The abundance of forager and ground-dwelling omnivores increased after selective cutting, whereas for the predator, scavenger, and seed disperser ants were decreased after selective cutting. Keywords: biodiversity, forest conservation, ground ant, selective cutting

Abstract

The upland rice-based cropping pattern is a form of double cropping or crop rotation in which upland rice as a basic commodity (base crop) which can be preceded or alternated with other food crops as a secondary crop. This study was conducted on dry land agro-ecosystems in the Tanimbar Islands Regency (West Southeast Maluku), from March to December 2017. This study was an adaptive research with a field experiment approach in farmer's land. The objective of this research was to obtain the most profitable cropping patterns, efficiency in land use and economically also has the highest net profit so it is appropriate to be recommended as a technology innovation for upland rice-based cropping patterns in dry land. The results showed that upland rice which was cultivated in multiple ways through intercropping or overlapped cropping, namely Introduced Cropping Pattern 1 (Upland Rice + Maize-Peanuts) and Introduced Cropping Pattern 2 (Upland Rice + Corn/Cassava-Green Beans-Peanuts) can increase land productivity (index planting of 222% and 288%, respectively) and farmers' income increased by 244-588% compared to upland rice grown in monoculture. Multiple cropping patterns can be recommended as a technology package for upland rice-based cropping patterns on dry land because of its efficiency in the use of production costs and land use. Furthermore, it gave the highest farm income of IDR63,933,100,-/ha/year with a net profit of IDR45,716,380,-/ha/year or IDR15,238,793,-/ha/ cropping season. Keywords: cropping pattern, farming, land use, upland rice

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

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
