Abstract

This study aimed to predict the need for lowland rice land, and evaluate the suitability of the land to meet food needs in the West Papua province. This study used a descriptive method with food demand projection techniques to predict the need for lowland rice land; and the technique of matching data on physical characteristics of land with land suitability criteria for lowland rice plants based on the Land Evaluation Technical Manual to evaluate the suitability of lowland rice fields. The projection result showed that the demand for food and land tends to increase every year, therefore, based on the comparison between food needs and the production, the West Papua province tends to experience a food deficit. An alternative to increase rice production is the extensification of paddy fields. The results of the evaluation of actual land suitability for lowland rice in the West Papua province ranged from the suitability class moderately suitable (S2) to marginally suitable (S3), with the limiting factor in the S2 land suitability class were nutrient retention (KB, CEC), available nutrients ( P2O5, N-total) and soil texture; while the limiting factors in the S3 land suitability class were slope, temperature and soil texture. If improvement efforts are made by adding organic matter and fertilization, then the distribution of potential land availability (available and suitable) is spread in very suitable land suitability classes (S1) and quite suitable (S2), with the largest land area being in Teluk Bintuni district.

Abstract

This study aimed to determine the carrying capacity of agricultural land in providing food to meet the needs of the population in Susweni Village, East Manokwari District. This study used the method of determining or comparing the carrying capacity of land by comparing the availability and needs of land. The results of the calculation of carrying capacity using the concept of calculation according to the regulation of the Minister of the Environment No. 17 of 2009 showed that the Susweni Village, East Manokwari District had a land carrying capacity status that was in deficit for the population living in Susweni Village, East Manokwari District. The availability of land of 78.47 ha and the need for land is 302,084 ha. Therefore, the need for land in the Susweni village is greater than the availability of land in the Susweni village. The deficit carrying capacity of the land in Susweni Village, East Manokwari District is strongly influenced by the population which continues to increase every year.

Abstract

Land degradation is the result of land use or utilization that exceeds the capacity of the land, which will cause critical land. The impacts that occur due to critical land include land degradation in the quality of soil properties, decreasing conservation and production functions, as well as affecting the social and economic life of the people who use the land. This study aimed to reduce the hazard of critical land, based on modeling changes in land cover/use using the Artificial Neural Network (ANN) method. The results of this study indicated that land classified as dangerous to become critical land includes sloping land with converted land cover/use. Reducing the risk of critical land hazard can be done by using land that is in accordance with the ability of the land, by following the rules of soil and water conservation, as well as the role of the government in conserving upstream areas that are oriented towards regional spatial patterns.

Abstract

The aim of this study was to identify the effects of the peel extract of red dragon fruit on the quality of tomato fruit during storage. Twenty one tomato fruits were immerced in the peel extract with concentrations of 0% (T0), 25% (T1), 50% (T2) and 100% (T3), where T0 to T3 represented the various treatment groups. Three fruits in each treatment were then randomly selected every two days, for quality analysis. The results showed that fruits from group T3 experienced lower weight loss when compared to T0, T1 and T2. Furthermore, there was no significant difference in the total soluble solids, and this indicates that the extract had no effect on fruit sweetness. Interestingly, fruits from T3 did not show any damage caused by fungus. In conclusion, the extract of red dragon fruit peel has antioxidant potential, which can be useful for food storage.

Abstract

Kandungan nitrogen dan kalium dalam selada umumnya rendah, yaitu kurang dari dua persen, sehingga masih memerlukan penambahan sumber lain untuk memenuhi kebutuhan tanaman. Kalium nitrat membentuk ion K+ dan NO3- setelah dilarutkan dalam air sehingga mudah tersedia bagi tanaman. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan kalium nitrat pada media tumbuh terhadap peningkatan pertumbuhan tanaman selada dan mengetahui tingkat kekritisan terhadap konsentrasi atau larutan hara listrik dengan penambahan kalium nitrat pada tanaman selada. Penelitian yang dilakukan berupa percobaan pot menggunakan Rancangan Acak Kelompok (RAK) dengan tiga ulangan. Perlakuan terdiri dari 12 tingkat konsentrasi atau EC larutan nutrisi dengan penambahan kalium nitrat. Hasil percobaan menunjukkan bahwa penambahan KNO3 berpengaruh sangat nyata terhadap peningkatan bobot segar dan berat kering pucuk per tanaman. Berat segar dan kering pucuk per tanaman meningkat secara nyata secara kuadratik dengan meningkatnya konsentrasi KNO3. Konsentrasi KNO3 yang optimum untuk pertumbuhan berat pucuk tanaman adalah 12,23 g dalam 100 L air atau konduktivitas listrik setara dengan 2,01 dS.m-1. Konsentrasi P dan K dalam jaringan pucuk tanaman meningkat nyata secara linier dengan pemberian KNO3. Konsentrasi N, Ca, Mg, S, Na Fe, Mn, Cu, Zn, Al dan B pada jaringan pucuk tanaman tidak terpengaruh KNO3.

Abstract

The program to increase food security is the government's main target in meeting the needs of the Indonesian people. Several programs have been carried out to achieve food security, including improving irrigation networks, optimizing land, and intensifying agriculture. Rice is a national food ingredient that is the main target, because it is still a staple food for almost all Indonesian people. Sorong Regency is part of West Papua Province which has relatively wide land potential for the development of agricultural commodities. This study aims to determine the cropping system and the effect of sago waste that is able to provide the highest productivity of the Mekongga cultivar rice plant in Sorong Regency. The research was conducted at the Experimental Ground of the Agrotechnology Study Program, Faculty of Engineering and Agriculture, Nani Bili Nusantara University, Sorong Regency. The research was carried out from July to November 2021. The research method used was an experimental method and the experimental design used was a single factor randomized block design, with nine treatments repeated three times. There are nine combinations of treatment systems for planting and giving sago waste. The results showed that the cropping system and the application of sago waste for rice (Oryza Sativa L.) cultivar Mekongga had a significant effect on plant heights of 42, 56, and 70 days after planting. The number of tillers at the age of 42, 56, and 70 DAP, the number of panicles per clump, the number of grains per panicle, the Legowo 4:1 planting system and with 300 grams of sago waste gave the highest number of grains per panicle.

Analysis of the growth of the Shoot Root Ratio, Stem Leaf Ratio and Leaf Weight Ratio on pagoda mustard plants are expected to provide an accurate picture of growth and yields. The aim of the study was to determine and analyze the growth of the shoot-root ratio, stem leaf ratio and leaf weight ratio of pagoda mustard greens (Brassica narinosa L.) due to the administration of liquid organic fertilizer Kascing, Papua Nutrient and MA-11. This research is held at the screen house of the Department of Soil Science, Faculty of Agriculture, University of Papua for 2 months. The tools and materials used include: machetes, hoes, polybag shovels, digital scales, 30 cm ruler, stationery, trays seedling, notebook, medication label, sprayer, hand spray, 10 ml liquid measuring tube, oven, f1 pagoda mustard seed, Kascing, Papua Nutrient, MA-11, granulated sugar, vegetable pesticide nem oil, soil media, compost, manure goats and cows. There is a significant effect due to the application of Liquid Organic Fertilizer on the Root Root Ratio, Stem Leaf Ratio and Leaf Weight Ratio. Analysis of variance and further tests showed significantly different results between the control treatment and other treatments (P1, P2, and P3). The results of the 5% BNJ test were carried out by comparing the average difference between each treatment, both P0, P1, P2 and P3 with a critical value of 3.2. Treatment of P1 Liquid Organic Fertilizer vermicompost can be said to have the most significant effect on plant growth variables because it shows the ratio of absolute average prices is greater than the critical value.
