The increasing need for transportation has prompted the government to provide public transportation to increase mobility and reduce the number of private vehicles. The Department of Transportation of Central Java Province has developed the Trans Jateng BRT (Bus Rapid Transit) mass transportation in the Barlingmascakeb area through activities to improve the Trans Jateng agglomeration transportation service. The BRT that has been operated in the Banyumas area is Corridor 1 on the Purwokerto-Purbalingga route. This study aimed to analyze the characteristics of travel behavior and passengers' willingness to walk. The sampling of the research was random sampling using a questionnaire as the main data collection tool. The results of the discussion of travel behavior in terms of the purpose of the trip were dominated by recreation/shopping and education. The majority of BRT users used public transportation as the mode used before switching to BRT, the connecting mode from home to shelter is dominated by feeders, while from destination to shelter is dominated by walking. The connection distance from the house and from the destination to the shelter is >400 meters. Thus, the majority of respondents came from a buffer range of 0-400 meters. Based on willingness to walk, some respondents walk up to a radius of >400 meters. It is necessary to add more shelter points if the distance between stopping points does not meet the standards and provide better shelter access, especially by walking or using other integrated public transportation.

The problem of setting tariffs is often a point of conflict between communities and managers. On the one hand, the community wants tariffs at the lowest level according to their capabilities with satisfactory service, on the other hand, the management wants high rates that can generate satisfactory profits. Basically, the determination of parking rates in accordance with the ability and willingness of the community will make it easier for users of parking facilities to pay the tariffs, especially if balanced with adequate services and facilities. Formulate the problem in this study is how the ability and willingness to pay parking users in the Banjaran Market area and whether the existing parking rates are in accordance with the ability and willingness of parking users in the Banjaran Market?. The method used in this study is descriptive analysis method, descriptive is a systematic, actual and accurate depiction of facts, data on events being studied. Analysis is the arrangement of data to obtain answers to questions that arise in research. For users of parking facilities for two-wheeled and four-wheeled vehicles on weekdays, the ATP value is obtained. The first hour tariff is Rp. 1,629.39, the progressive parking rate is Rp. 629, 39 WTP the tariff is Rp. Rp 1.388.08. For users of two-wheeled and four-wheeled vehicles on weekends, the ATP value for the first hour is Rp. Rp. 1,388.08 and the next hour tariff is Rp. 388.08 with a fixed WTP rate of Rp. 1388.08. From all calculations ATP is greater than WTP. The difference between the amount of ATP and WTP from the results of the analysis can occur due to several factors, one of which is the large percentage of parking fee allocation used as a component of ATP calculations that is not suitable for the tariffs applied at the Banjaran Market.

The survey of the distribution and damage of the new pest Spodoptera frugiperda is an important activity to determine appropriate control measures. In addition, the search for natural enemies is also needed as an alternative to controlling these pests. The purpose of this study was to determine the level of damage and the types of natural enemies found in several locations in Banyumas Regency. The method used is perposive random sampling in Banyumas Regency in five sub-districts, namely Ajibarang, Baturaden, Gumelar, Kedungbanteng, and Sumpiuh. Observations were made at 08.00-11.00 WIB from March to June 2021. The results showed that the attack rate of Spodoptera frugiperda larvae varied at each observation location. The highest attack rate was in Sumpiuh and Gumelar Districts, followed by Ajibarang, Kedungbanteng and Baturaden Districts. One species of parasitoid was found, namely Apanteles sp. and 9 predators, namely Oxyopes salticus, Dermaptera, Holcocephala sp., Rainieria sp., Orius insidiosus, Dolichoderus sp., Paratrechina sp., Oecophylla sp. and Conocephalus longipennis. At the individual paraistoid level, Apanteles sp. became the most common, followed by the predatory fly Holcocephala sp. and ants Dolichoderus sp., fly Rainieria sp., ladybug Orius insidiosus, Dermaptera, ant Paratrechina sp., ant Oecophylla sp. and the grasshopper Conocephalus longipennis.

Uncertain climate change impacts the difficulty of predicting the intensity of floods that hit rice fields in flood-prone areas, both the duration of the submerged plants and the height of the water surface. In order to evaluate the tolerance level and response of several local rice genotypes to submersion stress in the vegetative phase, 50 rice genotypes were screened (47 North Sumatran local varieties, 3 VUB), using special ponds to simulate flooding or inundation stress. The study used a separate plot design with three replications; the main plot was three immersion models, namely full immersion, partial soaking, and not soaking, and subplots of 50 rice genotypes. The immersion treatment was defined as a different growing environment. The results showed that in the fully submerged treatment, the recovery capacity of local rice plants only ranged from 0-20%. The new, improved varieties tested were Inpari 4 (susceptible), Inpari 3, 10, Ciherang, Inpara 2 (very susceptible), Inpari 30, FR13A (very tolerant). Submersion tolerant genotypes had a slight increase in plant height after being fully submerged. The chlorophyll content in the leaves decreased immediately after the soaking stress period (14 DAP) in all rice genotypes. The local rice genotypes tested were very susceptible to immersion; the new superior variety Inpari 4 was categorized as susceptible, while Inpari 30 and FR13A were very tolerant.

A microclimate is a complex of environmental variables that affect plants, including temperature, radiation, humidity, and wind. One of the additional atmospheric parameters that can be relevant in microclimate studies is the condition of atmospheric stability. The Richardson number derived from the temperature gradient and wind speed can determine the inversion interval in the atmosphere. The research was conducted at the Konawe Selatan Climatology Station to describe the condition of atmospheric stability and the convection process by calculating dynamic stability based on wind and temperature data at the level of 2 meters, 4 meters, and 7 meters in March 2021 from automatic tools. Based on observations in Condition 1, the atmosphere was seen in the morning dominated by neutral conditions, unstable in the afternoon, and stable in the afternoon. In condition 2 the atmosphere on a not rainy day and a rainy day in the morning was dominated by neutral conditions, free convection during the day, and forced convection at night. Free convection illustrated that the wind in the observation area was still dominated by monsoons and was still entering the rainy season. Also, forced convection illustrated that there was orographic rain; this was supported by the topography of the observation area, which was close to the hills and the Boroboro Mountains.

The abundance of pest and natural enemy populations on a land can be given in the diversity and abundance of feeding sources and other available resources. The purpose of this study was to determine the diversity of pests and natural enemies of sweet potato plants. Research on land with three types of sweet potatoes, namely yellow sweet potatoes with narrow leaves, yellow sweet potatoes with broad leaves, and sweet potatoes with white leaves. Around the research area are long beans, papaya, guava, soursop, and durian. Sampling of pests and natural enemies by using a pitfall trap. The data analyzed was in the form of the Shannon-Weaver (H') diversity index. The index of pest diversity of the order Coleoptera on narrow-leaved yellow sweet potato, broad-leaved yellow sweet potato, and white sweet potato was 0,160; 0,1270; and 0,1300. The index of pest diversity of the order Orthoptera on narrow-leaved yellow sweet potato, broad-leaved yellow sweet potato, and white sweet potato was 0,3585; 0,3599; and 0,3632. The index of pest diversity of the order Hemiptera on narrow-leaved yellow sweet potato, broad-leaved yellow sweet potato, and white sweet potato was 0,0635; 0,0771; and 0,1300. Diversity index of natural enemies of the order Araneae on narrow-leaved yellow sweet potato, broad-leaved yellow sweet potato, and white sweet potato 0.2180; 0.3061; and 0.2705. The three sweet potato fields had a low diversity index.

Tidal acid land is a potential land for cassava development. However, the development of cassava in tidal land faces many obstacles, one of which is the low availability of nutrients. This study aimed to determine the effect of NPK fertilizer in increasing the growth and yield of cassava in tidal land. The experiment consisted of two factors, the first factor was two varieties of cassava and the second factor was four levels of NPK fertilizer doses. The experiment was applied in a strip plot design with variety as the horizontal factor and the level of NPK fertilizer as the vertical factor and repeated three times. The growth parameters observed consisted of plant height, stem diameter, plant biomass weight, number of large tubers, number of small tubers, large tuber length, length of small tuber, the diameter of large tuber, the diameter of small tuber, the total number of tubers, the weight of large tuber, the weight of tuber small, and total tuber weight. The results showed that fertilizer application was effective in increasing vegetative growth and yield of cassava but increasing the dose of fertilizer was not effective in increasing the growth and yield of cassava. Differences in varieties generally did not show differences in vegetative growth and some yield components but still showed different results in the components of tuber length and total tuber weight.
