Abstract

Rice is a strategic commodity, so efforts to increase its production continue to be carried out, one of which is by increasing fertilization efficiency. The government has set policies in the field of fertilization, one of which is to provide fertilizer recommendations for rice plants based on specific location. The objective of this research was to evaluate the fertilization policy written in Permentan RI No. 40/Permentan/OT.140/4/2007. The methods were analyzing the variance values for each type of fertilizer recommended and validating N, P, and K levels in selected locations. The results of the study showed that the fertilization recommendations set by the government still need to be improved because there were still many discrepancies with conditions in the field. The adjustment of recommendation dose with the addition of organic materials were relevant and can be implemented, but it is still required further socialization to farmers. Reformulation of subsidized fertilizers, from NPK fertilizer 15-15-15 to NPK fertilizer 15-10-12 also had not been able to increase fertilization efficiency, because it actually made the dose of NPK becomes higher, but did not reduce the addition of a single fertilizer significantly. Subsidy policy also needs to be reviewed, because farmers did not fully get subsidized fertilizer so the farmers could not meet the needs of their fertilizers. Regarding the implementation of fertilization information, a soil big database must be created nationally to make specific location fertilization recommendations, and this must be easily accessed by farmers. Keywords: fertilization policy, organic material, soil big database, subsidy

Abstract

Imagery classification has long been used in analyzing remote sensing data. The use of the classification algorithm model can affect the results in interpreting benthic habitats in shallow water. This study aimed to determine the best classification algorithm model for mapping benthic habitat cover through Sentinel-2 satellite imagery. Three algorithm models were employed: Maximum Likelihood Classification (MLC), Minimum Distance Classification (MDC), and Mahalanobis Distance Classification (MaDC). The benthic habitat types were extracted using Lyzenga correction, giving three categories: coral, seagrass, and sand. The results showed that the application algorithm models of the MLC, MDC, and MaDC on the benthic habitat mapping resulted in an accuracy value that was not significantly different at the 95% confidence interval. However, of the three algorithms used, the MaDC algorithm provides the best results in overall accuracy (78.35%) than the MDC (74.45%) and the MLC (74.33%). It shows that the MaDC algorithm can be referred to as the mapped benthic habitat cover in the Kei Islands. However, this algorithm model needs to be continuously studied and compared to other models in other locations. Keywords: benthic, habitat classification, Kei Islands, sentinel

Abstract

The study aimed to descriptively capture livestock production and food waste and the suitability of border farms in the lowland Merauke region. Data were analyzed on livestock population structure (individual/ST), food crop waste production (dry weight, DW), capacity, and location quotient (LQ), and SWOT. Food crop waste production is 350 thousand tons of DW and so far only provided for ruminant cattle about 11%. Food crop straw waste is still dominated by rice straw (97%), followed by corn waste (2%), sweet potatoes, and peanuts. The capacity to increase the cattle population is close to 315 thousand ST. The LQ value of both livestock and food crops in Merauke is still in the range of 0 -<1 and is still a prospective sector to be optimized. The results of SWOT analysis conclude that the S-O strategy is the intensification and expansion of livestock commodities. Keywords: livestock population structure, location quotient, KPPTR, crop residues, Merauke

Abstract

This study aims to influence the use of monosodium glutamate (MSG) on soil chemical properties and the growth and yield of green spinach (Amaranthus gangeticus) on Silabukan soil. Spinach is grown in polybags with six types of MSG treatment: without MSG (control), with 3, 6, 9, 12, and 15 g, with three repetitions. This study used a Complete Randomized Design, and the differences between treatments were analyzed using the least significant difference and Duncan methods. Observations were made under the auspices of rain at the Faculty of Agriculture Lestari, Universiti Malaysia Sabah, for four weeks. The parameters recorded are the components of plant growth, namely the circumference of the trunk, the number of leaves, the height of the tree, as well as the yield components in the form of wet weights and dry weights. The parameters of soil properties selected are soil pH, electrical conductivity, salinity, cation exchange rate, available-phosphorus, carbon content, hydrogen content, and aluminum exchange, taken before and after planting. Based on the analysis, the use of MSG negatively affects the growth and yield of green spinach. On the other hand, the control treatment showed very high growth and yield. Therefore, using MSG is not recommended to increase the growth and yield of green spinach grown in Silabukan soil. However, MSG increases the soil's pH, electrical conductivity, and salinity. Keywords: Amaranthus gangeticus, agricultural soil, green spinach, soil fertility, soil pH

Abstract

Avian Influenza (AI) is an infectious disease on poultry with a high mortality rate, caused by Avian Influenza type A viruses from the family Orthomyxoviridae. For the layer chicken, the negative impacts of AI are the decrease of egg production until the death. The aims of the study were to analyze disease’s case data, measure the spread of disease, describe the distribution of disease, and mapping the risk of AI occurrence. The data were collected from the records of Dinas Peternakan dan Perkebunan by conducting interviews using the structured questionnaires. The data were analysed by calculating the incidence rate and performing a geographic information system (GIS) for mapping. The results showed that the highest incidence rate among sub-districts for 3 years was in Mattiro Sompe sub-district of 2.015 cases per 10.000 animals-year, while the lowest incidence rate among 3 sub-districts for 3 years was in Duampanua, Lanrisang, and Mattiro Bulu sub-districts of 0 case per 10.000 animals-year. The highrisk district was Mattiro Sompe Subdistrict, so that the control measures need to be emphasized in this area by increasing the biosecurity practices, depopulation and stamping out in new infected area, vaccination, surveillance, routine socialization, monitoring, and provide additional animal health facilities and human resources, especially the veterinarians, to optimize the disease control measures. Keywords: Avian Influenza (AI), incidence rate, layer chicken, Pinrang district

Abstract

As a densely populated industrial area in Bogor Regency, an urban farming program has been initiated in Gunung Putri District. The right strategy to develop and implement urban farming needs to be known so that this program is successful and sustain in Bogor Regency. This study aims to (1) identify aspects of preparation for urban farming development in Gunung Putri District, Bogor Regency; (2) analyze people's perceptions of its development; (3) and formulate its development strategy through qualitative descriptive methods, Likert scale, and SWOT analysis. Based on technical, social, institutional, commercial, financial, and environmental aspects, urban farming activities in this location are potential to be developed to support food adequacy and contribute to household income. The society has an excellent perception of the benefits. However, the community also saw obstacles, including the availability of respondents' time, usable land, capital, and supportive institutions. Most respondents also perceived that the currently limited information related to marketing has the potential to hinder the successful implementation of the urban farming. Nevertheless, the community's desire to participate is quite high, and they will participate if the program is implemented. The highest strength factor in developing urban farming businesses in Gunung Putri District is the public knowledge about cultivation techniques, while the most significant weakness is the marketing of its products. An enormous opportunity is to establish networking with various parties, and the biggest threat is the trend of urban life that does not focus on the agricultural sector. Keywords: aspects of feasibility, community perception, urban farming, SWOT analysis

Abstract

The drying performance technology is one of the most critical operations in copra production. This study aims to identify various drying methods in copra production and determine the best copra drying method based on the criteria of drying operation, environmental impact, and copra product quality. The research was carried out with the stage of identifying the drying methods of copra through literature studies and secondary data collection and continued with the stage of determining the best drying method using the composite performance index (CPI) method. Of nine drying methods, six range were identified as coconut processing scale 20–1200 kg, copra drying temperature 40–70°C, drying time 7.9-48 hours, drying rate 1.05–5.70%/hour, energy use 110.7–32140 kJ/kg-product, and the emission of 0.1–34.074 kg-CO2/kg-product. The nine methods of drying copra produce good quality copra based on copra product standards. Based on the calculation of alternative values using the CPI method, it has been shown that the best drying method was using a dryer with a drying temperature of 68°C and a drying rate of 5.70 %/hour. This drying method uses the energy of 14824 kJ/kg product and produces an emission value of 1.25 kg-CO2/kg product. The copra produced by this drying method gives 5% moisture, 60% oil, and 1% free fatty acid. Keywords: coconut, composite performance index, copra, drying technology

Abstract

By-products such as oil palm empty fruit bunches (EFB), palm kernel cake, and sawdust can be used as alternative feed. It contains nutrients needed by ruminants but is constrained by its high crude fiber content, including lignin, cellulose, and hemicellulose, and is low in protein. This study was conducted to evaluate the physical characteristics of the fermented media from plantation by-products using Pleurotus ostreotus as an alternative to ruminant animal feed. The experimental design was a completely randomized (CRD) with 3'3 factorial patterns with three replications. Factor A was the type of substrate, namely palm kernel cake, EFB, and acacia sawdust. Factor B was the length of fermentation, namely 0, 30, and 60 d. The data collected were analyzed by variance (ANOVA), and the results were significantly different. The observed variables were the mycelium growth rate, media weight, dry matter, organic matter, particle size, specific gravity, pile density, and compacted pile density. We conclude that the fermented sawdust gave the best growth speed of the P. ostreotus mycelia. The palm kernel cake substrate without storage showed good physical quality concerning particle size, pile density, and pile-compaction density. P. ostreotus fungus grew effectively and did not negatively impact the substrates' biomass, dry matter, and organic matter. Different substrate types give different physical characteristics to the P. ostreotus-fermented media. Keywords: acacia, empty fruit bunches, palm kernel cake, fermented media, Pleurotus ostreotus

Abstract

Unit Konservasi Budidaya Biofarmaka (UKBB) and Kampoeng Djamoe Organik Martha Tilaar (KaDO) are two medicinal plantation that possibly as resources for stingless bees nectar and pollen. This study was aimed to describe the foraging behavior of Tetragonula laeviceps in medicinal plantations, determine the plant species which become the pollen resources, and the distance between the colony and medicinal plants. Observation on foraging behavior were divided into three activities, i.e. flying out from the nest, returning the nest with pollen, and returning the nest without pollen. We found a similar pattern of numbers of bees returning to the nest with pollen in both UKBB and KaDO that occurred in the morning with the highest between 9 and 10 am and gradually decreased in the afternoon. The bees in UKBB showed highly number flying out from the nest in around 3 pm which might be the activites of resin collection. We identified 11 and 16 pollen types at the UKBB and the KaDO, respectively. The pollen in both locations are from the families Amaryllidaceae, Anacardiaceae, Clusiaceae, Cucurbitaceae, Ebenaceae, and Sapindaceae. Our results revealed that the distance range of medicinal plants from the bees hives was 13.4-113,3 m. Thus, this data indicate that the hives should be located in the distance of the bee forage. The medicinal pollen identified in the T. laeviceps pollen pot confirmed the role of the bees as the ecosystem service in the medicinal plantations. Keywords: foraging range, medicinal plants, pollination, pollen, Tetragonula
