Integration of logistic regression and multicriteria land evaluation to simulation establishment of sustainable paddy field zone in Indramayu Regency, West Java Province, Indonesia

One of the photokeratitis risk factors is acute reversible radiation of ultraviolet (UV) rays, which injure the cornea's epithelial tissue. Informal welding workers are susceptible populations to UV rays exposure. This study aimed to confirm the influence of UV radiation exposure on photokeratitis complaints in welding workers in Cimanggis, Depok, West Java. A cross-sectional study was conducted from February to June 2019 and used to select 100 welding workers purposively. A semi-structured questionnaire was used to determine photokeratitis complaints, age, education level, eye protection, safety knowledge, and work period; the UV radiation measured by A UV meter. Data were analyzed using a logistic regression test. We found the proportion of photokeratitis to be 84.0%, with 76.0% of UV radiation exceeding the Threshold Limit Values (TLV). The logistic regression test showed a significant effect of UV radiation on photokeratitis after controlling confounding variables (education level, eye protection, safety knowledge, and welding distance) (p-value = 0.006; AdjOR = 7.236; 95% CI: 1.74–30.07). It can be concluded that UV radiation, more than TLV, constitutes the primary risk factor for photokeratitis complaints. Risks for photokeratitis were influenced by low education level, poor eye protection, limited safety knowledge, and welding distance ≤ 45 cm.

Farmers in the paddy field farming faces some fundamental problems caused by the narrower tenure due to increased population and land inheritance, creation of breakthrough technologies to increase the productivity of rice farming and farmers' income increasingly difficult for farmers to diversify motives are often more oriented to the income stabilization. West Java is better known as the rice granary, is also a center of vegetables in Indonesia. Vegetable farming has been fused with the local community, especially for upland farmers. The last few years this development not only in vegetable crops in the highlands but try also try in the lowlands in the paddy field. Along with the above conditions, the policy support necessary to achieve the expected results. One obstacle in the application of vegetable farming is the lack of use of the means of production as a result of lack of financial ownership of farm households. The purpose of research is (a) reveals variability of farm crops especially <br />vegetables Onion, Long Beans, cauliflower and cucumbers. (b). And to evaluate the extent to which government policy support for horticultural commodities especially vegetables in West Java. The research was conducted in two districts of Indramayu (Chilli Red, Red Onion and Cauliflower), Falkirk (cucumber and bean length) of West <br />Java Province. , Amounted to a total of 50 respondents drawn farmers. The results showed that farm incomes various vegetables (horticulture) is higher than the income of rice farming, especially in the red pepper (673%), onions (415%), while the rate of return based on a variety of vegetable farming is higher than the benefits of rice farming, especially red pepper (776%), onions (279%) cauliflower (200%) and beans (144%).

There are significantly decreasing of rainfall in wet season and dry season, and changed in onset of early season, that all of them can make crouded in plan of planting date, field actifity especially for food crops africulture. In the other side, climate is one of condition that has been ready and can not change, where probability of climate change will be reality that should be happened every time. Increasing frequency of climate extrem will give high impact in agriculture, especialy in rice-based farming system. This paper describes the climate risk based on statistical approaches. The climate risk is focused on flood and drought event. The analysis used was a chance occurrence based on time series data of rainfall and flood/droughts (affected and puso) based on median value from time series data. The goal of this research are : (1) to know rainfall critical value that can be influence flood and drought event in some of central food crops i West Java, (2) to know probability of flood and drought event in some of central food crops in West Java. The result of this research show that critical value of the rainfall that can be influence flood and drought event is very variety. Average of for flood event for paddy field near coastal based on median approach is 140 mm/month with probability 0,6. For another location, 166 mm/month with probability 0,68. Average of critical value of the rainfall for drought event is 64 mm/month for paddy field near coastal with probability 0,73. For another location, critical rainfall value is 119 mm/month with probability 0,76. For spesific research or detail scale (district or sub distric) we can use rainfall critical value and probablity based on data in that specific location because the data is more representative local riil condition.

Penelitian ini bertujuan untuk mengkomparasikan akurasi metode ANN dan LR dalam memprediksi perubahan lahan sawah di Kabupaten Purworejo. Adapun data masukan yang dibutuhkan adalah peta lahan sawah tahun 2008, 2015 dan 2019 hasil interpretasi visual citra satelit resolusi tinggi dan faktor pendorong perubahan lahan sawah. Hasil penelitian menunjukkan bahwa model prediksi lahan sawah yang dibangun dari ANN dan LR secara umum memiliki akurasi yang sama-sama baik. Tetapi jika dilihat dari total nilai false alarm dan misses, model CA yang dibangun dari ANN lebih baik dari LR. Hasil penelitian ini juga menunjukkan bahwa dalam rentang tahun 2008 sampai 2019, luasan lahan sawah di Kabupaten Purworejo berkurang sekitar 194.01 Ha. Kata kunci: artificial neural network; cellular automata; logistic regression; perubahan penggunaan lahan; sawah. This research aims to compare the accuracy of the ANN and LR methods in predicting changes in paddy fields in Purworejo Regency. The input data required is a map of paddy fields in 2008, 2015 and 2019 as a result of visual interpretation of high-resolution satellite imagery and the driving factors for changes in paddy fields. The results showed that the paddy field prediction model built from ANN and LR generally has the same accuracy. But if it is seen from the total value of false alarms and misses, the CA model from ANN is better than LR. This study shows that from 2008 to 2019, the area of paddy fields in Purworejo Regency decreased around 194.01 Ha.

The objective of this research to investigate traditional agricultural irrigation based on indigenious knowledge of customary urug societies in Bogor West Java. The research method use is Ethnoecology qualitative approach. This method is implemented because research have conection among human (cultural & social) and environment including traditional agriculture water management as well as the knowledge about environment. Data are collected by in-depth interview, observation and documentation. In order to determine respondents as major sources information use purposive sampling technique. The outcome is analized with combination numerous of method such as in-dept interview, observation, and documentation (triangulation data). There are some results including rice paddy field in Urug societies exert traditional terrascering for inventing land for cultivating of paddy because geograhpycally location of wet land paddy is mountainious. The another is traditional irrigation of Urug slue river water (main sources of irrigation) to to susukan (traditional reservoir). After that water is flowed to Selokan and continue to rice paddy field. The person who have mandatory for water agriculture management is mentioned as Ulu-ulu. Ulu-ulu is pivotal person because have chores for ensuring all farmer received water from river, Susukan and selokan. The other finding is Urug customary societies applicate gotong royong (mutual cooperation) among member of societies typically in traditional agriculture irrigatin activity.
