Every year, West Java Province becomes the third largest rice-producing province in Indonesia, with a production of 9.43 million tons in 2022. However, this condition is inversely proportional to the welfare of food crop farmers when viewed from the exchange rate of food crop farmers (NTPTP), which in the last two years has been below 100%. The purpose of this study is to evaluate the effect of rice crop production, rice crop productivity, the selling price of dry milled grain, production costs, and additional capital on NTPTP in West Java. Secondary data were obtained from the Central Bureau of Statistics and the Directorate General of Food Crops, Ministry of Agriculture, from 2010–2022. Multiple linear regression analysis is used to examine the determinants of the welfare of food crop farmers. The findings of this study show that the selling price of dry-milled grain has a significant effect on increasing NTPTP. In contrast, rice crop production, productivity, production costs, and capital increases are not. The selling price of dry-milled grain influences the welfare of food crop farmers in West Java. Government policymakers can use this study in the agricultural sector to overcome the high expenditure of farmers' production costs by providing subsidies on target and maintaining the cost of goods sold for rice for the welfare of farmers in West Java. Keywords: price of dry grain, exchange rate of food crop farmers, paddy production, paddy productivity, multiple linear regression

Sugar cane (Saccharum officinarum L.) is the main ingredient in sugar production. Sugarcane is widely cultivated in warm and tropical areas and is widely used as a sweetener because it contains a lot of fructose and glucose. National sugar production shows a decline, the majority of which is caused by pathogens, especially the fungus Bipolaris sp. capable of producing up to 85% damage per Ha if no control is applied. Biological control using Trichoderma spp. can control this pathogen and is able to promote sugarcane growth. The purpose of this study was to determine the effectiveness of Trichoderma spp. in controlling Bipolaris sp. in vitro. The results showed isolates TD1, TD2, TD3 were able to inhibit Bipolaris sp. antagonistically and volatilely, the antagonist test showed a result of 86% (TD1) while the volatile test of 65% (TD2). Conclusion Trichoderma spp. can inhibit the growth of Bipolaris sp. on an in vitro scale. Keywords: BCA, Bipolaris sp. Trichoderma spp. ABSTRAK Tebu (Saccharum officinarum L.) merupakan bahan utama dalam pembuatan gula.

The severity of disease symptoms is affected by triangular interactions between pathogens, hosts, and the environment. This study aims to describe the severity of tungro disease symptoms concerning the resistance of rice varieties and various fertilization rates. The research used the potting method in the Center for Rice Research, Sukamandi greenhouse. The experiment was designed using a Randomized Design, with 3 varieties: Ciherang (sensitive), IR 64 (green leafhopper resistance), and Inpari 36 Lanrang (virus resistance) as the main plot, and 4 levels of combination fertilization: (1) compound fertilizer + without urea; (2) compound fertilizer and urea 250 kg/ha; (3) compound fertilizer and urea 350 kg/ha; and (4) compound fertilizer and urea 500 kg/ha, as subplots. The data was processed using Anova and Duncan's multiple distance test. The results showed that rice variety significantly affected vector preference and the severity of tungro symptoms. The dose of nitrogen fertilization does not give different results to the preferences of insects and the severity of tungro in the greenhouse. There is no interaction between the variety and the dose of fertilizing. Resistant varieties are less preferred by green leafhoppers than the sensitive varieties. Keywords: antixenosis, Nephotettix virescens nitrogen fertilizer, preference

Pulu mandoti is a local type of rice that is fragrant and rare. This glutinous rice has a high selling price and can only thrive when planted in Salukanan Village. However, its productivity is still relatively low, so efforts are needed to sustain the farming business. This study aims to analyze farmer households' livelihood patterns and sustainability strategies. The respondents were 50 farmers selected using simple random sampling. The data were analyzed in descriptive, qualitative, and quantitative ways. The results showed that the pattern strategy of pulu mandoti rice farmer households is an intensification and extensification strategy in agricultural landuse, and diversification strategies in the livestock, service, trade, and employment sectors. The sustainability of farming livelihood patterns resulted in an index of 89.66%, included in the sustainable category. The government needs to pay attention to production factors that affect the productivity of pulu mandoti rice farming so that farming can be sustainable.

Rice cultivation without land as an urban farming method is carried out to produce food in a subsistence manner. This experiment aimed to examine the response of rice plants to non-soil planting media based on alternate wetting-drying irrigation. This work was conducted at the screen house in Sumberjeruk Village, Jember Regency (8°07'42.9" S and 113°47'09.3" E) from January to May 2022, using a factorial, fully randomized design of 2-factors with 3-replications. The planting medium without soil (husk:water) as the first factor consists of 4 compositions (v/v): 0:1, 1:4, 1:6, and 1:8 (total volume of 25-L media), while variety as the second factor consists of Inpari 46 and IR 64. The results showed that the combination treatment (husk: water) 1:6 and Inpari 46 had a significant effect on the number of productive tillers (25.17 stems) and grain weight per hill (34.07 g). The planting medium of non-soil husk: water 1:6 gave no significant value to husk: water 1:4 on the total number of grains (124.21 grains) and full grains (83.52 grains). The Inpari 46 varieties showed the highest value for the total number of grains (133.07 grains), the number of full grains (84.88 grains), and the weight of 1000-seeds (22.43 g). The application of husks and water as a planting medium with the right ratio is an ideal medium for landless rice cultivation since it can supply oxygen to the media.

Developing strategic land use issues into agrotourism is increasingly prevalent in Batu City. This condition raises various kinds of farmers' perceptions about who feels the benefits of the presence of tourism. Various backgrounds make these differences in perception even more visible. This study aims to analyze the influence of farmers' characteristics on their perceptions of developing "Bon Deso" agrotourism in Tulungrejo Village, Batu City. The location of the study was determined deliberately with consideration for agrotourism activities. "Bon Deso" is located in the village. This study used quantitative survey methods with data collection techniques through interviews, observations, and instruments. The data were analyzed using descriptive statistics and simple linear regression. The population was 646, with a sample of 87 farmers obtained by calculating the Slovin formula. A simple random technique determined the sample. The results of this study show that characteristic variables simultaneously affect perception. The characteristic sub-variables that affect perception are age, length of formal education, farming experience, and land area. Characteristic sub-variables that do not influence perception are non-formal education and primary income. This finding could be used as a reference for agrotourism managers in determining programs that suit farmers. It is hoped that the presence of a program will get support and participation from farmers to maximize the development of "Bon Deso" Agrotourism.

Java long pepper (Piper retrofractum Vahl.) is a potential export commodity. One of the centers of Java long pepper production in Indonesia is Sumenep Regency. However, in marketing, farmers only act as price takers, and prices fluctuate a lot. This study aimed to describe the structure, conduct, and performance of the Java Long Pepper market in Bluto District, Sumenep Regency. Sampling was carried out using the snowball sampling method to obtain a sample of 31 farmers, 2 small traders, and 1 large trader. The analysis technique used is the SCP (structure, conduct, and performance) with qualitative and quantitative approaches. Market structure is analyzed by calculating CR and IHH, market conduct by analyzing pricing methods, marketing channels, and marketing functions, and market performance by marketing margin and farmer’s share. Based on the research results, it is known that the market structure that occurs is an oligopsony with a high concentration and collusion price leadership types by the dominant firm. Market conduct shows that farmers cannot bargain, and traders determine absolute prices. Market performance is seen from marketing channel I which is considered the best, with a marketing margin IDR2.000,00 and a farmer’s share of 97.30%. This condition of imperfect market competition needs to be controlled and paid attention to so that it can be managed well, create healthy business conditions, and avoid monopoly.

Collagen derived from the eggshell membrane, is an increasingly popular functional material. Native chicken is one of the leading local commodities whose industrial waste has the potential to be used as collagen raw material. This study aimed to evaluate the nutrients and morphology of the eggshell membrane of native chicken eggs as raw material for collagen production. The parameters observed were morphology using electron scanning microscopy, mineral composition, and collagen nutrient content (water and protein). SEM observations showed that the eggshell membrane of native chicken eggs was fibrous. The meshed fiber form represents the extracellular matrix present in collagen proteins. The eggshell membrane contains Cl, K, Ca, P, and Mg macrominerals at 1.696%, 1.796%, 14.30%, 0.437%, and 0.146%, respectively. Microminerals I and Mo were also found at 0.00034% and 0.00014%, respectively. The moisture content of the superior native chicken eggshell membrane decreased by 13.05% after the collagen extraction (p<0.05), with a crude protein content of 25.32% after the extraction. It was concluded that the eggshell membrane of native chicken eggs produces fibrous morphological characteristics that are meshed and contain high minerals so that they have the potential to be used as raw materials for collagen production in various applications.

Native chicken is one of the leading local commodities whose industrial waste has the potential to be used as collagen raw material. This study aimed to evaluate the nutrients and morphology of the eggshell membrane of native chicken eggs as raw material for collagen production. The parameters observed were morphology using electron scanning microscopy, mineral composition, and collagen nutrient content (water and protein). SEM observations showed that the eggshell membrane of native chicken eggs was fibrous. The meshed fiber form represents the extracellular matrix present in collagen proteins. The eggshell membrane contains Cl, K, Ca, P, and Mg macrominerals at 1.696%, 1.796%, 14.30%, 0.437%, and 0.146%, respectively. Microminerals I and Mo were also found at 0.00034% and 0.00014%, respectively. The moisture content of the superior native chicken eggshell membrane decreased by 13.05% after the collagen extraction (p<0.05), with a crude protein content of 25.32% after the extraction.

This study aims to describe the status of soil fertility and corn yield on different slopes of agricultural land in UPT SP3 Saritani Village, Boalemo Regency. The study used survey methods at 3 land slope locations (20--30%, 30–40%, and 50–60%), determined purposively. Soil samples and maize yields were analyzed quantitatively and descriptively. Corn yields were collected and compared over 3 harvesting seasons based on the parameters of agronomic components. Soil fertility was analyzed at BSIP PALMA Manado laboratory, with parameters including macronutrient components. An essential finding of this study is that there is a difference in corn yield and nutrients on the sloping lands. The fertility status of farmers' land on the average sloped land of the three stations is very low levels of nitrogen and carbon nutrients and high levels of phosphate and potassium. The agronomic components of Stations 1 and 2 were relatively similar compared to the yield of components at Station 3. In the 3 harvest seasons, Station 1's yield decreased every season; from Station 2 it also decreased, but only at the time of the third harvest, although it was insignificant. The yield from Station 3, the steepest field, decreased significantly. Keywords: bisi 18 hybrida, maize, sloping land, soil fertility
