Abstract

The potential lines of West Papua local waxy corn has been already obtained in the previous studies, but the yields have not been further tested. In seed certification for the release of varieties from plant breeding results, it is necessary to conduct multilocation tests to obtain stable and superior yields in various locations. The aim of this research is to test the continued yield of potential lines of West Papua's local waxy corn at several areas in West Papua Province. The study was conducted in Prafi and West Manokwari Districts. The method used was an observational method using a Randomized Complete Block Design of 2 factors: Factor 1 was treatment of 7 local corn genotypes and factor 2 was treatment of 2 locations. Each treatment was repeated 3 times. Variables were observed included yield components of the maize genotypes tested. The data obtained were analyzed using ANOVA and if it had a significant effect, further BNJ test was performed at 95% confidence level. The results showed that productivity (seed weight ha-1) of the 7 genotypes tested were: 1) Ranging from 2.72 tons ha-1 (KM-BC3F1) to 7.66 tons ha-1 (AM-BC3F1 ) in the Prafi District, 2) from 3.30 tons ha-1 (AP-BC3F1) to 7.46 tons ha-1 (KL) in the West Manokwari District, and 3) from 3.28 tons ha-1 (KM-BC3F1) to 5.92 tons ha-1 (AM-BC3F1) in the G x L interactions. Genotype AM-BC3F1, AP-BC3F1, and P have higher productivity in Prafi District, on the contrary genotype KM-BC3F1, KP-BC3F1, AL, and KL have higher productivity in West Manokwari District.

Abstract

The purpose of this study was to determine the types of phytochemical compounds in the organs of the bark, leaves, roots and seeds of the zodia plant. Dried materials from zodiac plant organs (roots, bark, leaves, and seeds) were macerated with ethanol compounds for 3x24 hours, then distilled so that the ethanol compounds evaporate, then macerated again with methanol solvent to obtain a clear macerate, and ended with evaporation with a rotary vacuum device at 50oC. The results of simplisia were identified various phytochemicals contained in each organ through GCMS chromatography tool type QP-2010. Types of phytochemicals are identified and what are their concentrations, as well as how their potential for the development of agricultural products from each zodiac plant organ are the objectives of this experiment. The chromatograms identified various phytochemicals, namely, 56 types of roots, 23 types of leaves, 18 types of stem bark, and 13 types of seeds. Benzene, cyclopentane, and hexane compounds were present in all four organs tested, typical compounds in roots (nonadecane), stem bark (aristolone), leaves (evodiamine and selin), and seeds (longiverbenone). Some zodia plant phytochemicals act as antimicrobials, antifungals, and antibacterials, so they have the potential to be utilized as industrial materials for upstream agricultural products.

Abstract

ABSTRACT Kombucha is a beverage made from tea as its basic ingredient and fermented by active starter of microbial consortia. The flavor of this fermented beverage is determined by many factors, such as supplementation of the main raw ingredient with various fruits, sugar, and types of tea used as its main raw ingredient. The main objective of this research was to elucidate the effect of fruit supplementation (addition of Fuji apple and strawberry) on the organoleptic quality of the products, following incubation periods of 4, 8, and 12 days. A triplicate complete randomized factorial design (types of fruits combined with incubation period) was applied in the experiment. Organoleptic tests (include taste, aroma, and color of the products) were conducted by applying quisionere method involving 7 panelis. The results showed that types of fruits and incubation period significantly affected (p<0.05) the organoleptic quality of the kombucha products. Overall, combination of stroberry and incubation period of 4 days gave the best results (p<0.05) when compared to control (commercially sold kombucha) and other treatments, indicating that such product has potential to be widely commercialized. Keywords: Alcohol, fermented beverage, fermentation, kombucha, organic acids ABSTRAK Kombucha merupakan minuman hasil fermentasi yang terbuat dari bahan dasar teh setelah diinokulasi dengan mikroba starter. Cita rasa kombucha sangat ditentukan oleh penambahan suplemen, seperti gula, buah-buahan, dan jenis teh yang dipakai. Tujuan utama penelitian ini untuk mengelusidasi pengaruh penambahan jenis buah (buah apel dan buah strobery) dan lama waktu fermentasi (4, 8, dan 12 hari) terhadap kualitas organoleptik produk kombucha yang dihasilkan. Penelitian ini menggunakan rancangan acak lengkap factorial (jenis buah yang dikombinasi dengan lama fermentasi) dengan 3 kali ulangan untuk setiap kombinasi perlakuan. Uji organoleptik (rasa, warna, dan aroma) dilakukan dengan metoda kuesioner yang melibatkan 7 orang panelis. Hasil penelitian menunjukkan bahwa jenis buah dan lama fermentasi berpengaruh nyata terhadap tingkat kesukaan panelis pada produk kombucha. Secara keseluruhan, perlakuan kombinasi penambahan buah stroberi dan waktu fermentasi selama 4 hari memberikan hasil terbaik, dan berbeda nyata dengan kontrol maupun perlakuan lainnya. Hal ini mengindikasikan bahwa produk penelitian ini berpeluang untuk dipasarkan secara luas. Kata kunci: Alkohol, asam organik, fermentasi, kombucha, minuman terfermentasi

Abstract

Mustard consumption increases due to population growth, therefore it is necessary to increase its yield. One of the cultivation techniques to increase the growth and yield of green mustard can be done by the right plant spacing. This study aims to examine several plant spacings in two planting periods on the growth and yield of green mustard. The research was carried out from April to June 2020, at the Experimental Field of Agriculture Faculty Papua University, Manokwari, West Papua. This study was laid in a Randomized Block Design (RAK), with 3 spacing treatments, namely 25 cm x 15 cm, 25 cm x 20 cm and 25 cm x 30 cm. Each treatment was repeated 5 times. The data was analyzed using analysis of variance at the 95% confidence level, and if it had a significant effect, it was continued with the Least Significant Difference Test (BNT) at the 95% level. To see the comparison of mustard yield between the first and second studies, tabulated analysis was used. The results of the first and second studies showed that the three treatments tested had a significant and very significant effect on the character of plant weight per plant, per plot, and yield per hectare. The 25 cm x 15 cm plant spacing resulted in the highest yield per plot or per hectare. Plant spacing of 25 cm x 15 cm was 12 tons/ha produced the highet yield. On the other hand, a spacing of 25 cm x 30 cm produced the highest yield per plant. The growth and yield components decreased in the second study, except at a spacing of 25 cm x 15 cm which capable of producing 10 tons/ha.

Abstract

The main focus of this research is to examine the impact of the existence of the Final Processing Site (TPA) on the physical condition of the surrounding environment and the socio-economic conditions of the surrounding community. In this study, physical conditions were measured based on Surface Water Conditions, Shallow Ground Water Conditions/Wells, Air Quality, and Soil Quality. The impact on the socio-economic conditions to the community was measured based on the emergence of new livelihoods, health, and main livelihood income. The data will be analyzed using the Spearman Rank correlation method, where the X variable is the impact of the presence of the landfill and Y1-Y7 variables were the impact on the physical environment and socio-economic conditions of the community. The results of this study are that the physical condition of the waste landfill in Sowi Gunung has a negative impact on the community and the environment around the landfill. The social conditions caused by the landfill in Sowi Gunung do not affect the people living around the landfill. The correlation analysis of the relationship between the existence of the Sowi Gunung Final Disposal Site (TPA) on physical environmental conditions including surface water, shallow groundwater/wells, air quality, soil quality with low to very low correlations. The correlation between the socio-economic conditions of the community: livelihoods, health, and income around the TPA, has a low to very low correlation.

Abstract

Kampung Jawa is one of the slums in Manokwari Regency, West Papua Province and the Regency government claims the area as a slum area with regional regulations in 2015 and 2020. Over time; The area is growing so rapidly because, the location of Kampung Jawa is in the economic strategic area of ​​Manokwari Province, namely the Center for Trade, Trade and Services, West Regency of Manokwari Province. The physical development that occurs in the area without any planning process for the wild area of ​​Manokwari Province, so that it has an impact on storage activities. so that the arrangement of buildings in this area is inadequate. Worries about a condition if there is no immediate response by stakeholders (government, community, and private sector) so that it will have a massive environmental degradation impact on the coastal area of ​​Wosi Bay. The aims of this study were 1) to determine the characteristics of the development of slum settlements and the level of slums in Kampung Jawa, Teluk Wosi Area, West Manokwari District; 2) Formulating a strategy for developing slum settlements in Kampung Jawa, Teluk Wosi Area, West Manokwari District; 3) formulating or planning an alternative concept of structuring the coastal area of ​​Kampung Jawa that is good, sustainable and in line with the Manokwari Regency Regulations, as well as applicable laws and regulations. This research is descriptive and uses two methods of analysis, namely quantitative to answer the first problem and qualitative to answer the second and third problems. The results showed that the settlement of Kampung Jawa was included in the typology of the village with the heavy category of slums. The results of the SWOT analysis obtained alternative handling strategies, namely the strategies generated based on a combination of two elements of strength (internal) and elements of opportunity (external) to overcome existing weaknesses and threats. The concept of structuring the area is carried out by applying the concept of a waterfront city with physical and non-physical development based on the original characteristics and functions of Kampung Jawa.

Abstract

Wosi is a sub-district located in Manokwari Regency and is a part of the Wosi River Alisan Area (DAS) which has vulnerability to forest cover due to the conversion of settlements and trade centers. Based on this, it is necessary to mitigate the flood disaster structure or carry out flood risk management. One of the government's efforts or policies in flood risk management in Wosi Village is to restore the function of the Wosi watershed through relocation. The Willingness to Pay (WTP) and Willingness to Accept (WTA) approaches related to relocation problems can estimate the WTP and WTA values so that they can optimize the form of policies in reducing flood risk. The results of the analysis show that first, Willingness to Pay flood disaster management through relocation is significantly influenced by education level, income, number of dependents, length of stay and area of residence. Willing to accept a compensation fund of approximately Rp. 32,000,000 to Rp. 506.666,666 and Total WTA is around 1,096,000,000. WTP funds that are willing to be paid are Rp. 82,655,533 (Average WTP) and Rp. 2,479,666,000 (Total value of WTP). The amount of Willingness to Accept is smaller than Willingness to Pay, proving that the paired comparison method can reduce the WTA-WTP gap. In addition, the community's understanding of flood risk reduction in the Wosi watershed is still not optimal, so that the efforts of all parties, especially the local government, in carrying out various policies, plans, and programs that can contribute to risk reduction.
