Various data analysis methods can make thermal comfort prediction models. One method that is often used is multiple linear regression statistical analysis. Regression analysis needs to be checked for accuracy with other analytical methods. This study compares the making of a thermal comfort prediction model with regression analysis and naïve Bayes analysis. The research method used quantitative methods for data collection regarding thermal comfort. The thermal comfort variable, consisting of eight independent variables and one dependent variable, was measured at Wonosobo High School, Indonesia. The analysis to make the prediction model was carried out with two different analyses: multiple linear regression analysis and naïve Bayes analysis. The results show that naïve Bayes is more accurate than multiple linear regression analysis.

In the rainy season the condition of the channel on Jalan banyumas Km 7 Wonosobo Regency is not able to accommodate the flow of water so that flooding often occurs. Because of that, it is necessary to redesign new drainage channels. This research is quantitative, the method used is to analyze both hydrologically and hydraulically to get the best drainage building design. From the calculated data, it can be concluded that the drainage channel on the Banyumas km 7 Selomerto road must be expanded or dredged at certain channel points where the expansion must take into consideration the current conditions in the field. For the most discharge (Q) is in the QF section with a discharge of 0.13517 m3 / second and the lowest is in the G7 segment with a discharge of 0.00308 m3 / second. From the calculation results obtained that channels 2, 3, 4, 5, 6 and 7 must be redesigned and made a new building.

The Industrial Workers' Flats, located in the Batang Integrated Industrial Area, are supporting facilities workers use. The building was previously planned using conventional methods. In many cases, demands for fast and efficient construction work often occur, especially in the case of high-rise buildings. The need for multi-storey buildings encourages the need for an economical structural design that can be implemented quickly and efficiently without reducing the stiffness between the components of the building structure. From the explanation above, it is re-planned using the precast concrete method so that the work is neat, precise, and fast. In this planning, the SRPMK system is used. It needs good supervision in precast concrete, especially in joints, because precast joints are not as monolithic as conventional ones. It is necessary to develop precast technology to be more innovative in its use and easier to apply.

Patakbanteng and Jojogan villages are located in the mountains of the Dieng plateau, where there are many springs, but there is no agency or party to provide clean water, although now a small part of the population still uses clean water from wells. For this reason, it is necessary to plan a clean water network for residents who do not have access to clean water. This research was conducted by collecting data in the field, including primary data covering conditions and water resources, spring discharge, elevation and pipelines to consumers, while secondary data covering population, population growth ratio and village maps. The spring discharge of Sendang Panguripan Gunung Prau is 172 m3/sec, to meet the water needs of the people of Patakbanteng Village and Jojogan Village with a population ratio in the 15th plan year is 4193 people according to the pre-design calculation of the required discharge of 5.27 lt/sec.

Di kabupaten Wonosobo terdapat bendung tandu yang sudah lama dibangun untuk mengaliri area irigasi seluas 240 Ha yang belakangan ini mengalami masalah pada lahan pertanian warga yang memanfaatkan bendung tandu. Masalah yang dialami warga yaitu jumlah ketersediaan air yang kurang memenuhi pada area persawahan, bahkan tak sedikit yang mengalami kekeringan panjang dikarenakan air irigasi sudah tidak mengalir lagi ke sawah tertinggi atau terjauh. Oleh karena itu perlu adanya perencanaan ulang bendung tandu. Perencaan bendung tandu melalui tahapan perencanaan badan bendung yang didapat dari hasil analisa debit banjir rencana. Perhitingan Debit banjir rencana ini menggunakan metode rasional dengan periode ulang 50 tahun. Acuan yan didapat dari curah hujan kabupaten wonosobo sehingga mendapatkan debit banjir rencana 430,72 m3/dt. Dimensi saluran primer dengan perhitungan saluran pasangan didapat lebar bawah 0,6 m dengan tinggi air 0,47 m, tinggi jaggaan 0,4 m sesuai aturan tabel koefesien strikler. Panjang saluran primer direncanakan 200 m.
