Abstract

ABSTRACT: This study aimed to examine the knowledge, attitudes, preferences, and consumption patterns of agarwood tea in KPHP Unit XXIII Sarmi, Papua Province. This research was conducted in Tetom Jaya, Kiren, Bebon Jaya, and Srum, which cultivate agarwood. The sampling procedure for respondents is based on the Slovin formula and a structured questionnaire. The data were then analyzed using a Likert scale and the smart PLS-SEM statistical analysis in further detail. The level of community knowledge regarding the consumption of agarwood tea from both internal and external sources is enough (40-59,99%) - excellent (80-100%). Attitudes are included in the less (20-39,99%) – good (60-79,99%) categories, while preferences are included in the good (60-79,99%) category, and behavior is included in the insufficient (<40-59,99%) category. In addition, the PLS-SEM analysis indicates that T statistics are more significant than 1.96 and p-values are less than 0.05, indicating that exogenous latency variables from external, internal, and attitudes influence preferences, influencing the consumption of agarwood tea sachets.

Abstract

ABSTRACT: Celery is an agricultural crop that has long been cultivated by indigenous Papuan people who live in the Arfak Mountains Regency because the soil structure and climate are suitable for growing celery. Currently, Arfak Mountains Regency is an area that fulfills the celery needs of Manokwari Regency so that celery plants become a source of income for local residents. One of the cultivation problems experienced by farmers is nematode disorders which cause celery to not grow to its genetic potential and even die. This is known by the presence of a kind of knot on the roots which causes abnormal growth in celery. Therefore, the aim of this research is to identify the nematodes that cause root knots and control them biologically using 2 natural control agents for Marigold plants, namely Tagetes erecta and T. patula. This plant produces yellow and red flowers and has a strong odor. The method used is a descriptive method with observation techniques. Data analysis was carried out using the Spearman Correlation test which was narrated with the help of tables and pictures. The research results showed that root knots were identified as being caused by 3 nematode species, namely Meloidogyne javanica, M. incognita, and M. arenaria. The differences between the three nematode species are known through identification of the vulva morphology found in each species. The research results also show that both Marigold species produce 2 types of secondary metabolite compounds, namely phenols and flavonoids, which function to trap and control the population and spread of nematodes. The presence of marigold plants causes celery to achieve maximum growth, number of branches and wet stover weight in suitable with its genetic potential.

Abstract

ABSTRACT: Sidey District has the potential to become a West Papuan tourism icon. Sidey needs to prioritize the development of the tourism industry to guide future development planning. The objective of this study is to identify the key priorities for enhancing the tourism potential in Sidey District. The priorities are segmented into three categories: priority development criteria, priorities concerning tourism actors, and priorities related to tourism alternatives. The descriptive approach is used, and the analytical hierarchy process (AHP) facilitates decision-making. The collection of data involved conducting interviews with 7 experts, including academics, local community representatives, and regional government officials, using a questionnaire. Analysis of the questionnaire processing revealed a consistency value below 0.1, indicating that the weighting is deemed acceptable. According to the study, sidey's tourist potential may be divided into three categories: eco-edutourism, agro-edutourism, and build tourism. According to the findings of the AHP calculations, the allocation tourism development budget (35%) and institutional solid support (27%) were the two most important development criteria. The local government (34%) and the community (24%) are significant tourism actors. Eco-edutourism (48%) and agro-edutourism (40%) are the main alternatives to tourism growth. The alternative development follows the Manokwari Regency RIPPARDA's preferred course of action.

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.

Abstract

ABSTRACT: Tomandin Fakfak nutmeg (Myristica argentea Warb) is an important source of income for the people in Fakfak. The plantation development of this nutmeg requires knowledge of plant propagation techniques, one of which is through cuttings. This study aims to study the effect of giving commercial auxin (Rootone), and auxin in the form of a mixture of NAA, and IBA on the success of Tomandin Fakfak nutmeg cuttings, both using cutting materials from seedlings and adult plants. The study was designed in a Complete Randomized Design (RAL), with auxin treatments: control (without auxin), Rootone applied in paste form, a quick dip in IBA/NAA solution (1000/500 ppm), and IBA/NAA (2000/1000 ppm). The research was carried out in 2 (two) sets of research, i.e. using cutting material from seedlings and adult plants. The results showed that the propagation of Tomandin Fakfak nutmeg plants through cuttings was prospective to be developed as an alternative plant propagation technique, even though the success was still low. The best treatment of seedling origin shoot cuttings was found in the application IBA/NAA solution (1000/500 ppm), with rooted cuttings of 12.5%. Cuttings of shoots from adult plants are only able to form calluses, with the highest live cuttings (56.25%) in the treatment of IBA/NAA (1000/500 ppm) and IBA/NAA (2000/1000 ppm).
