Abstract

Rice is one of the important food commodities in Indonesia. The extensification of swamp land is expected to play a role in supporting the increase in national rice production. The objective of this study was to evaluate the performance of promising strains of swamp rice produced by BB-Biogen breeding tolerant to Fe poisoning in the shallow swamp area of Sorong-Southwest Papua. The experiment used a randomized block design (RBD) with three replications and 17 genotypes as treatments. The observed characters include the growth and yield component characters. Data analysis included analysis of variance to find out the differences between each test lines and continued with the LSI test to obtain the expected lines that performed well and were superior in the Sorong lebak swamps. The results of the analysis of variance showed that there were significant differences in all the characters tested. The results showed that TT, JAT and JAP showed the best results including the G21 and G11 lines, the G7 line had the highest percentage of filled grain, the G6 line had the heaviest 1000 grain weight. While the G1 and G7 lines had the highest yields per plot equivalent to 6.15 and 5.92 t/ha,

Abstract

 The aim of the study was to analyze the value of coastal local wisdom of the indigenous people of Jeflio Island for the development of mangrove ecotourism. In the research method used qualitative and quantitative approaches. Data analysis includes analysis of local wisdom values. Based on research, the Jeflio community has local wisdom in the form of calls for conservation known in the form of recommendations such as "Nani Mi Wawolom Ti Eges Gu" (the native language of the Moi tribe), Pamali (prohibition) in certain areas/areas, Sasi - Customs and ceremonies," barapen" as well as local handicrafts such as making senate/mats, woven bags, "bayayai", boats, oars and spears. Local Wisdom Through Advice “Nani Mi Wawolom Ti Eges Gu” comes from the language of the Moi tribe which means protecting nature together. Local wisdom, such as local skills, traditional ceremonies and local values, is a cultural tourism attraction that can be empowered by tourism managers as creative industries to develop mangrove ecotourism to attract tourists and support local community economic development. One of the improvements in existing facilities in the Jeflio Mangrove Ecotourism Area is a souvenir shop that can be used to sell local Jeflio community crafts. In order to maintain and maintain the infrastructure of the Jeflio Mangrove Ecotourism Area, local wisdom values such as mutual cooperation and togetherness are very much needed. There are still weaknesses in the use of local wisdom in Jeflio because local wisdom owned by the community has not been legitimized.

Abstract

Food is one of the fundamental requirements that must be fulfilled for everyone. The Food Balance Sheet (FBS) is one of the tools used to describe the food situation of a region. This study aims to analyze and project the requirement of food crops in Manokwari using a dynamic system modeling, i.e. paddy, soybeans, corn, peanuts, green beans, cassava, and sweet potatoes. Generally, this research consists of 4 (four) main stages, i.e. data inventory, data analysis, system dynamic model design, and projection of the requirement of food crops until 2050. The research showed that in 2022 some food crops production is in deficit, i.e. rice, soybeans, and green beans. Furthermore, corn, peanuts, cassava, and sweet potatoes are surplus. One of the solutions to supply food consumption in Manokwari Regency until 2050 is increasing food crop production through the expansion of food cropland and the use of superior varieties. In addition, increasing the Crop Index (CI) of rice plants from 2 times a year to 3 times a year is an alternative solution to increase rice production due to limited agricultural land provided by the government.

Abstract

Nutgrass is a common weed often found in agricultural fields. Its high population in agricultural land can have negative implications for farmers as it may prevent farmed crops from growing and producing as well. However, nutgrass has the potential to be developed into a biopesticide due to its phytochemical compounds. The purpose of this study is to identify secondary metabolite compounds present in nutgrass extract. On nutgrass extracts, the study used phytochemical screening techniques with ethanol (polar) and n-hexane (non-polar) solvents. According to the findings, ethanol and n-hexane solvents produced nutgrass extract yields of 10.81% and 0.65%, respectively. Alkaloids, flavonoids, saponins, tannins, and steroids were all present in nutgrass extracts made with ethanol, whereas only steroid components were present in extracts made with n-hexane. Saponins, tannins, alkaloids, flavonoids, and steroids are only a few of the secondary metabolite substances found in nutgrass extracts.

Abstract

is a fungicide in agriculture that is used for various types of fungi and plant diseases, mainly applied to plant foliage, and is also used as a soil or seed treatment. For this reason, it is necessary to confirm the composition or active substance in the fungicide sample so that it can work as intended. To ascertain the composition of the active substance, a test concentration analysis method is required, namely iodimetry titration. Before a method is used as a standard method, it is necessary to verify the method so that this method provides precise and thorough results. The verification process involves several parameters, namely precision, accuracy and linearity with the acceptance requirements for each parameter being % RSD < 2 % for precision, % recovery in the range of 98-102 % and determination > 0.9970 for linearity. From the tests that have been carried out, it was found that the precision parameters had a % RSD of 0.017320%, the accuracy parameters had a %recovery of 99.80% and the linearity parameters had a coefficient of determination (r2) of 0.027. The results of research on samples showed that Ziram 96% TC levels varied between 95-95.03%. This range is within the permitted content limits based on the CoA (Certificate of Analysis), namely 95-95.2%.

Abstract

Yenusi Village and Ruar, Biak Timur District, Biak Numfor Regency, respectively represent the mangrove rehabilitation caused by the 1996 tsunami by the Environmental Agency of Biak Numfor Regency in 2014 and the natural mangroves in this area. The success of rehabilitation activities can be seen not only from the presence of mangrove species but also through water biota. The aim of the research is to determine the diversity of macrozoobenthos biota in Yenusi Village as a representation of rehabilitated mangroves and Ruar Village as a representation of natural mangroves in the East Biak District, Biak Numfor Regency. Based on the results of the analysis, it is known that there are 43 types of macrozoobenthos from 4 classes, 21 families with a total of 3,263 individuals which include 34 types of snail groups (Gastropoda), 5 types of shellfish groups (Bivalvia), 2 types of shrimp groups (Crustacea), 2 types of groups of marine worms (Polychaeta) with species diversity index values ​​in these two mangrove areas of 2.61 (Ruar village) and 2.99 (Yenusi village) with the criteria "medium. 74.2% of macrozobenthic individuals were found in the mangrove area of ​​Yenusi village and the remaining 25.8% were found in the mangroves of Ruar village which shows that there is quite good adaptation of the species considering that the presence of macrozobenthic species and individuals in the mangrove rehabilitation area (Kampung Ruar) is much higher than natural habitat (Yenusi Village)

Abstract

Momiwaren Village is one of the villages close to the Momiwaren Protected Forest Area. In line with regional development and technological advances, knowledge of the use of plants as medicinal ingredients is starting to disappear. For this reason, it is necessary to conduct research on how many types of plants are still used by the community as medicinal ingredients. The method used in this research is a survey method with interview techniques. The results of this research show that the people of Momiwaren Village still use plants as medicinal ingredients. There are 30 species from 22 families used by the community. If we look at the conservation status of the plants used, the types of plants used are still included in the naturally available (LC/DD) category, but there is one type of plant that is threatened with extinction and requires further silvicultural action so that this plant can be cultivated and not extinct from nature.
