Abstract

Sorong is one of the most advanced and most populous cities in the province of West Papua, with a population of 2016 reaching 232,833 people and a population growth rate of 3.21 percent per year (BPS, 2016). As the most populous city, of course, the problem of waste becomes a significant threat, especially related to the increasing volume of waste production both from households and businesses and also the tendency to dispose of waste improperly that results in environmental pollution. The purpose of this study was to determine the extent of environmental pollution due to plastic waste in the City of Sorong, then look further at the management of mineral water plastic bottles, and determine what factors influence the amount of plastic bottle waste in the City of Sorong. The analytical method used in this research is descriptive qualitative analysis. Based on the results of the study it can be seen that the waste management process is carried out by several parties, among others: carried out by the Government using an integrated management system, then by the community with an individual management system, and by the private sector through the Sorong Raya Garbage Bank. Factors that influence the amount of plastic bottle waste include: The level of community / business actors' knowledge about waste, their attitude about waste management, their behavior in managing waste, and the activities of government administrators such as studies on waste, socialization of facilities and regulations, and the adequacy of the APBD budget. and also external participation.

Abstract

Transportation is very instrumental directly in the process of development, due to the transportation community easily perform the displacement from a site to the other, thus accelerating the growth of the economy in large cities and villages. However, such transport is not feasible and provide negative impact to the environment in the form of air pollution. The purpose of research was to (1). analyse large concentrations of CO, HC, CO₂ and O₂ in the emission gas exhaust, (2). analyse the effect of emission gas exhaust of vehicles public transport, and (3) analyse the influence of the characteristics of public transport vehicles against the concentration of CO and HC test emissions existed in the District Manokwari. The research was a kind of quantitative research where all the data needed for the analysis were obtained directly. The data directly required were data obtained by measuring the amount of emission, the characteristics of the operational public transport, interviews, and analysis of regression linear multiple by using SPSS 25. The results of the study showed that the average amount of emission gas exhaust of public transport vehicles in the District Manokwari is CO at 2.13 %, HC at 534.60 ppm, CO₂ at 12.96% and O₂ at 2.71%. Most of the public transport operating in the city of Manokwari issued emission gas exhaust exceeded the threshold limit that has been set and has the potential to pollute the air or do not pass the test of emissions by 63.50% and only 36.5% in transport public passed the test of emission gas exhaust. In addition, the results of the test emission coefficient of the regression were simultaneously throughout the variables affecting the emission of CO and HC.

Abstract

Common corn rust disease caused by the fungus Puccinia sorghi, causes small spots on the upper and lower surfaces of the leaves which then spread to the entire leaf surface, causing a decrease in photosynthetic yield. Losses due to this disease are 45-60%. This study aims to explore the resistance of corn varieties to rust disease. This research was arranged in a descriptive research design using 240 plants of corn. The maize varieties tested were Pertiwi 3, Betrass, Bissi 2, Bissi 18, Bima, and Prafi Merah varieties. The results showed that the intensity of disease increased continuously every week from the first appearance of 5 WAP to 11 WAP. At 11 WAP the severity of the disease was 76% Pertiwi 3, Betrass 91%, Bissi 2 82%, Bissi 18 89%, Bima 80% and Prafi Merah 92% so that all test varieties were classified as susceptible varieties. The susceptibility was triggered by the test variety's gene system which was not sufficient to inhibit the rate of development of pathogens with high virulence. In addition, weather factors with rainfall ranging between 73and 90%, adequate optimal temperatures ranging between 25.7oC and 28.8oC and heavy rains that occur continuously for 24-26 days strongly support production and sporadic distribution in the crop resulting in an increase in severity disease.

Abstract

Salah satu daerah yang membudidayakan jagung secara terus menerus setiap musim di Manokwari adalah Kampung Copti Prafi. Kondisi ini menyebabkan mudahnya berkembang penyakit karat daun. Oleh karena itu, tujuan penelitian ini adalah mengevaluasi intensitas serangan penyakit, laju perkembangan penyakit, sifat ketahanan jagung dan pengaruh faktor-faktor iklim terhadap intensitas dan laju perkembangan penyakitnya terhadap penyakit karat daun jagung tersebut. Analisa data dilakukan secara tabulasi dan menggunakan gambar yang dihasilkan dari microsoft excel 2016 untuk membandingkan variabel-variabel pengamatan. Hasil penelitian yang diperoleh menunjukkan bahwa patogen penyebab penyakit karat di Kampung Copti adalah Puccinia polysora. Intensitas serangan dimulai pada 5 minggu setelah tanam, kemudian terus-menerus mengalami peningkatan hingga minggu ke 11 dimana semua varietas yang diuji menunjukkan respons peka. Laju perkembangan penyakit juga mengalami peningkatan seiring dengan meningkatnya intensitas serangan dan dikategorikan berat. Curah hujan sangat menunjang perkembangan penyakit. Peningkatan jumlah curah hujan dapat menyebabkan peningkatan perkembangan penyakit karat. Curah hujan menyebabkan lahan pertanaman menjadi basah dan menimbulkan evapotranspirasi yang menyebabkan kebun menjadi lembab dan memudahkan distribusi penyakit dari satu tanaman jagung ke tanaman jagung yang lainnya pada kebun yang sama atau antar kebun. Kondisi perkembangan penyakit yang meningkat juga disebabkan oleh kepekaan tanaman terhadap ras patogen yang sangat virulen terhadap tanaman jagung.

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

ABSTRACT: The research aims to determine the effect of PGPR application on the incidence of fusarium wilt disease and tomato plant production. The research was carried out using a Randomized Group Design (RAK) with one treatment factor, namely the PGPR dose. Treatment was made in five levels, namely D0 (control/no PGPR), D1 (5 cc PGPR/liter air), D2 (10 cc PGPR/liter air), D3 (15 cc/liter air) and D4 (20 cc PGPR/liter air air). The results of in vitro PGPR testing provided an inhibitory response to Fusarium growth with an average of 47.32% on PDA media and 63.12% on NA media. The PGPR dose treatment tested did not have a significant effect on plant height, number of leaves, production characteristics and disease intensity, except for the average number of branches per tree, root length and root weight. Giving a dose of 20 cc/liter is the best dose to increase root character and number of branches.

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

This study aims to determine the effect of giving several organic fertilizer formulations to the intensity of soybean leaf rust disease and its production, which in turn can increase farmers' income in this area. The study was conducted using randomized block design (RBD) with 3 replications. The treatments were husk ash, compost, chicken manure, and goat manure. The parameters observed included leaf rust disease intensity, disease progression rate, plant height, number of leaves, number of branches, weight of 100 seeds and weight of seeds per plot. Data analysis was performed using Analysis of Variance (ANOVA), if the treatment has a significant effect, it is followed by the DMRT test at the 95% level. The result showed that (1) the fertilizer formulation given caused different responses to the parameters of soybean rust disease intensity, plant height, number of leaves, number of branches, weight per 100 seeds and weight of seeds per plot, (2) The best fertilizer for controlling soybean leaf rust disease is goat manure, and (3) the best fertilizer formulation to produce production is abusekam with a production of 2156.66 gr / plot (equivalent to 3.594 tons / ha)
