Abstract

Estimation of evaporation rate is needed in hydrological data, especially in irrigation and drainage planning data. The method for estimating the evapotranspiration rate recommended by FAO is the Penman - Monteith method, however apart from this method there are still several methods that can be used if the data obtained in the field are different. Evaluation of the method of estimating the rate of evapotranspration is expected to help in choosing the right method when different data is obtained, so with this evaluation, we can see the accuracy of the methods. The methods that are closest to accuracy with the Penman - Monteith method are Hargreaves, Makkink, Turc, Blaney-Cridlle and Penman. If ordered based on the ranking of the evaluation results, the method that is closest to the Penman - Monteith method is Hargreaves, because of all the evaluation variabels Hargreaves has the best evaluation value. While the closest model based on the best R2 value is the Jensen-Haise model, but the error value of this model is very high.

Abstract

Kenyamanan ruang dapat mempengaruhi perilaku dan psikologis penggunanya. Kenyamanan ruang yang perlu untuk diperhatikan diantaranya adalah kenyamanan termal dan kenyamanan visual. Masyarakat terbiasa menggunakan alat ukur suhu berupa termometer dan alat ukur intensitas cahaya berupa lux meter untuk mengetahui kondisi ruang. Alat ukur tersebut menghasilkan besaran suhu dan intensitas cahaya yang terukur tanpa disertai justifikasi apakah memenuhi baku mutu atau tidak. Tanpa mengetahui pemenuhan baku mutu, tingkat kenyamana termal dan visual tidak dapat ditentukan. Untuk itu diperlukan alat ukur yang dapat mengukur suhu dan intensitas cahaya sekaligus menentukan tingkat kenyamanannya berdasarkan kesesuian dengan baku mutunya. Pada penelitian ini dilakukan perancangan alat ukur kenyamanan termal dan visual ruangan dengan menggunakan mikrokontroller arduino uno, yang dilengkapi dengan sensor DHT11 untuk mengukur suhu dan kelembaban relatif udara, sensor BH1750 untuk mengukur intensitas cahaya. Penentuan tingkat kenyamanan termal berdasarkan baku mutu yang tertera dalam SNI-03-6572-2001 dan baku mutu kenyamanan visual berdasarkan SNI-03-6575-2001. Hasil kalibrasi antara sensor dengan alat ukur standar yakni environment meter diperoleh hasil rata-rata persentase error yang berada dalam batasan wajar. Nilai rata-rata persentase error pembacaan sensor parameter suhu, kelembaban relatif dan intensitas pencahayaan tanpa cover berturut-turut bernilai 1.56%, 2.95%, dan 0.76%. Pada penggunaan tutup pada sensor menghasilkan nilai error berturut-turut 1.74%, 2.73%, 1.31%. Prototype ini membagi tingkat kenyamanan termal menjadi tig akelas yakni Sejuk Nyaman (SN), Nyaman Optimal (NO) dan Hangat Nyaman (HN). Jika suhu udara yang terbaca kurang dari 20.5 oC atau lebih tinggi dari 27.1 oC maka alat akan menampilkan sebagi kondisi Tidak Nyaman (TN). Kenyamanan visual terbagi menjadi 2 yakni Nyaman (NM) jika hasil pengukuran pada rentang 120 – 250 lux, di luar rentang niali tersebut ditampilkan sebagai kondisi Tidak Nyaman (TN). Hasil tersebut menunjukkan alat monitoring yang dibangun dapat beroperasi dengan baik karena nilai pembacaan mendekati sebenarnya.

Abstract

The rapid development of Depok City has led to a high demand for the construction of facilities for housing and commercial areas. This can result in a decrease in water catchment areas, which can cause water shortages and flooding. The purpose of this study was to identify and create a map of water catchment areas using a geographic information system (GIS) and analyze the infiltration rate and cumulative infiltration in Depok City. The method used was spatial data extraction and spatial analysis of the condition of the water catchment area by scoring potential infiltration and actual infiltration. Spatial analysis was also performed by overlapping spatial data for water catchment area zoning. Infiltration measurement using a double-ring infiltrometer based on SNI 7752:2012. Infiltration rate analysis using the Horton model. The mapping results show that Depok City is dominated by slightly critical criteria, covering an area of 15,589.327 ha (77.98%), followed by conditions that are starting to be critical, covering an area of 4,146.347 ha (20.75%), and natural normal conditions, covering an area of 168,515 ha (0.84%). The highest infiltration rate was measured in Cipayung at 0.330 cm/minute, and the lowest was recorded in Cilodong at a rate of only 0.110 cm/minute. The smallest cumulative infiltration value was 15.744 cm/h, and the largest was 51.886 cm/h.

Abstract

Construction projects always have uncertainties even in small projects, especially in terms of time and cost. This study aims to identify and analyze the dominant risks in home renovation projects in Vimala Hills Bogor and design mitigation strategies. Data collection was carried out by distributing questionnaires to all project implementers. Data analysis used the severity index method to measure frequency and severity combined with biserial point tests and KR-20 to measure the validity and reliability of 15 risk variables with 30 respondents directly involved in the project. The results showed that there were two dominant risks in the high category, namely bad weather conditions (frequency of 80,00%, impact of 77,50%, and risk value of 16) and change of work (frequency of 56,67%, impact of 64,17%, and risk value of 12). Other risks are in the medium to low category. The mitigation strategies implemented include adjusting work schedules based on weather forecasts, protecting work areas, finalizing the design before construction begins, and implementing formal procedures for work changes. After mitigation, the risk value of the two dominant variables dropped to the low category. These findings confirm the importance of implementing risk management even on small scale projects to prevent delays and cost overruns and increase efficiency so that contractors can achieve optimal project goals in the future.

Abstract

In irrigation and agricultural planning, the crop coefficient value plays an important role in calculating water planning on land. This study aims to calculate the crop coefficient (Kc) of rice in a Nonpowered Automatic Fertigation (FONi) irrigation system combined with a minapadi system as a reference for irrigation planning. This study was conducted experimentally for 99 days in Dramaga, Bogor, using the FONi Minapadi system consisting of a fiberglass tank, a water supply tank, and an automatic float to maintain the water level. Actual evapotranspiration (ETa) data were calculated based on water balance, while potential evapotranspiration (ETo) was modeled using five methods: Penman-Monteith, Turc, Hargreaves, Makkink, and Blaney-Criddle. Model validation was performed using linear regression against the Penman-Monteith method as the standard reference. The results show that the total ETa during the observation period was 421.93 mm. Among the ETo calculation methods, the Turc model provided results closest to the Penman-Monteith method, with a coefficient of determination (R²) of 0.741 and the lowest sum of squares error (SSE) of 56.026. The calculated Kc values varied throughout the rice growth phase, with the highest value of 1.84 observed during the reproductive phase. The relatively high Kc value reflects significant water demand in the FONi Minapadi system, influenced by system characteristics and environmental conditions. This study concludes that the FONi Minapadi system has the potential to improve irrigation management efficiency in integrated agriculture. However, further research is needed to understand the influence of technical and environmental factors on the Kc value and to compare it with other irrigation systems.
