Abstract

ABSTRACT : With the limited location and space available for livestock land and to prevent social conflicts that arise in society, due to the impact of environmental pollution from livestock activities, methods or methods are needed to reduce the impact of environmental pollution due to livestock activities, one of which is by modifying feed rations by fermentation method as carried out by the Manokwari Integrated Flamboyan Group. Based on this, it is necessary to measure the level of environmental pollution from pig farms that use fermented feed and to determine the levels of ammonia and methane produced. Measurement of public perception was carried out using a Likert scale and measurement of estimates of ammonia gas and methane produced using estimates based on the production of livestock manure produced. The overall perception of respondents for pig breeders who use fermented feed, all respondents stated that they were not very disturbed, while pig breeders who did not use fermented feed stated that they were quite disturbed. The results of statistical tests show that there is no difference in the estimates of ammonia and methane gas produced by pig breeders who use fermented feed and pig breeders who do not use fermented feed. This shows that the public's perception of pig farmers who do not use fermented feed is quite disturbed due to rations given.

Abstract

ABSTRACT: Byak Indigenous people use Inoknson (noken) as a source of income apart from making houses, machetes, and boats. System of knowledge and art in the life circle of the Biak people understand Inoknson as a medium of communication and expression of life that is lived collectively because it is closely related to the functions, symbols, and meanings of symbols of each Inoknson type and size. The study aimed to identify species of plants used as raw material for inoknson, describes raw material extraction, drying, dyeing, and waving process, as well as the conservation status of the selected plant species. The descriptive method with participatory observation and interview techniques is employed in this research. The results showed Inoknson raw materials are from the inner barks of three species namely: Warmas (Melochia umbellata), Mandwes (Juncus effusus), and Anfan (Hibiscus tiliaceus). The Warmas is more the preferred raw material because it is stronger and more durable. The IUCN 2022 conservation status of the three plant species is the Least concern. The process of making Inoknson starts from taking raw materials, peeling and cleaning the barks, drying the fibers, separating and forming fibers, coloring and weaving Inoknson, and marketing. The transfer of knowledge about inoknson only delivers to women, from mother to daughter or to their relatives interested. Warmas raw materials are collected from the surrounding secondary forest, carried out at a certain time, by collecting from three plants with a diameter of 10-20 cm with a height of ± 2 meters. This method is one of the traditional conservation concepts carried out by the Byak tribal community in maintaining and conserving the raw materials of inoknson.

Abstract

ABSTRACT: This research aims to find out the types of ameliorant and the local West Papua genotypes that have the best influence on corn productivity, identify the yield of several promoting genotypes of the local West Papua red corn using several types of ameliorant in North Manokwari District, and know the right type of the ameliorant for increasing the yield of several promoting genotype of the local West Papua red corn. The study used a split-plot design with the combination treatments of ameliorant types and corn plant genotypes. The types of ameliorant as the first treatment factor which was allocated as a main plot consisted of Control or without ameliorant (Ao), Chicken Manure (A1), and Goat Manure (A2). The second factor (G) as a subplot consisted of 8 types of corn genotypes (AMP-UNIPA 1, AMP-UNIPA 2, AMP-UNIPA 3, AMP-UNIPA 4, AMP-UNIPA 5, AMP-UNIPA 6, AMP-UNIPA 7, and AML-UNIPA (local varieties). The results showed that the combination of ameliorant and corn genotypes treatments produced a different influence on the growth and yield components of corn. Several important variables in the growth component as well as the corn yield component showed the best results as an influence of goat manure ameliorant application.

Abstract

ABSTRACT: This research was conducted at Klamana, KM 14, East Sorong District, Sorong City, Southwest Papua Province, with the objective of analyzing the correlation between water, dry matter, and sugar level and measuring the sensory properties of root storage on several local Papuan sweet potato genotypes. The research used an experimental method with a Randomized Complete Block Design on 5 sweet potato genotypes (Local Sorong, Mokwam, Koya-4, Koya-5, Soribo), which were repeated 4 times, so that there were 20 experimental units. The results showed that Local Sorong and Mokwam genotypes produced the highest sugar content (14.2 and 15.2 Brix), whereas Soribo genotype produced the highest dry matter content (40.58%), followed by Koya-4 and Koya-6. The correlation coefficient results show that there is a very strong positive relationship between water content and tuber sugar content with a value of r = 0.94, whereas a strong negative correlation coefficient is shown by dry matter content and tuber sugar content with a value of r = 0.94. Based on the testing on sensory characteristics, most of the panelists liked the color of the steamed tubers of Local Sorong, Mokwam, and Koya-4 genotypes. The taste sensory were preferred more in the Local Sorong and Mokwam genotypes by the teenage or younger age category panelists, while Koya-4 was more in the category of mature age panelists. The texture and fibrous feel of the local Sorong and Mokwam steamed tubers were preferred by most of the panelists, because the tuber flesh of both genotypes are soft, easy to digest and smooth.

Abstract

ABSTRACT: Manokwari Regency is located in a tropical climate zone that experiences high rainfall in the rainy season so that it has the potential as an area for rainwater harvesting. Rainwater can be used as a source of clean water through rainwater harvesting by applying a filter system. This study aims to design a simple rainwater filtration system and analyze the quality of the filtered rainwater. The filter system is designed using layers of natural materials, in order from top to bottom are gravel, sand, charcoal and juk. Filtered rainwater samples for 3 different rain events were taken for quality testing based on physical parameters and chemical parameters. The results showed that physically, the filter system was able to reduce suspended material (TSS) in rainwater, however, the mineral content in the filter material contributed greatly to the increase in dissolved solids (TDS). Chemically, water passing through the filter system has a consistent increase in concentration of pH, nitrate, iron and sulfate parameters, but is able to reduce hardness and ammonia content In terms of quality, all filtered rainwater samples are still in the clean water quality standards and drinking water standards according to Minister of Health Regulation No. 2 of 2023 and Government Regulation of the Republic of Indonesia No. 22 of 2021 concerning class I water quality standards annex VI, while for pure rain, the chemical content with ammonia parameters does not meet the standards of class I water quality standards annex VI of Government Regulation of the Republic of Indonesia No. 22 of 2021.

Abstract

ABSTRACT: The dynamics of the change in forest cover and its impact on carbon dioxide emissions in Papua Province over the 32 years, from 1990 to 2022. The research was carried out from April to May, using secondary data consisting of land cover maps, slopes of slope, and forest function on a scale of 1:250.000 and administrative territory boundaries on a scale of 1:50.000. The analysis methods involve codification processes, map overlay, land cover change analysis, and CO2 emission calculation. Research results show that during the period, Papua Province suffered significant deforestation. Deforestation was recorded at 256.065 ha at an average rate of 8.002 ha/year, while forest degradation reached 965.955 ha with an average speed of 30.186 ha/year. Further analysis shows that Sarmi district is the region with the highest level of damage, with deforestation of 35.507 ha and forest degradation of 292.860 ha. The impact of deforestation and forest degradation on carbon dioxide emissions is also very significant. Deforestation accounts for about 174.720.433 tons of CO2, with an annual average of 5.460.014 tons of CO2/year, while forest degradation contributes about 193.584.910 tons of CO2, with an average yearly of 6.049.528 tons of CO2/year. Deforestation and forest degradation in Papua Province are complex and interrelated. The leading causes are economic, mining, and social factors. As a result, these findings suggest that the Papua Province needs better forest conservation and management measures and the development of sustainable policies to maintain the sustainability of forest ecosystems and reduce greenhouse gas emissions.
