Abstract

This research aims to design an open circuit wind tunnel with a piv (particle image velocimetry) system. This particle image velocimetry system was chosen because this system has the advantage of being easy to make and the equipment used is not too complicated. The method used in this design is a mathematical calculation method with. This tunnel is designed to have dimensions of 8 meters long, 1.75 meters wide and 1.75 meters high. With a maximum planned wind speed of 30 m/s. The design results state that the head loss in the test section is 1.28 m, in the contraction chamber is 0.52 m and the head loss in the diffuser is 0.49 m so the total head is 2.29 m so a pump power of 11.94 hp is needed to be able to simulate a maximum wind flow of 30 m. /s

Abstract

Pesatnya pertumbuhan ekonomi dan berkembangnya industri di dunia yang mengharuskan masyarakat Indonesia memiliki sumber daya manusia yang kompeten, kreatif, dan multitalenta. LKP sebagai lembaga yang mewadahi urgensi yang dihadapi pada kalangan masyarakat, mulai dari kurangnya pemanfaatan potensi alam dan rendahnya perekonomian masyarakat. Lembaga Kursus dan Pelatihan kerja (LKP) Faeyza Jaya Media yang berlokasi di kota Tanjung, Kabupaten Tabalong, Kalimantan Selatan yang melayani kursus dan pelatihan di bidang komputer. Akan tetapi proses pencatatan dan pengelolaannya masih bersifat manual dicatat dalam pembukuan sehingga memerlukan waktu lama dalam pembuatan laporan yang berkaitan dengan kegiatan kursus. Oleh karena itu dirancang aplikasi berbasis web dengan metode waterfall menggunakan bahasa pemrograman PHP yang dapat membantu proses rekapitulasi hasil data siswa yang sudah registrasi dan yang belum registrasi, pembayaran, jadwal dan kelompok kursus, data pengajar, penilaian dan pembuatan sertifikat menjadi sistematis, efisien dan efektif dalam menunjang aktifitas LKP yang lebih kondusif dibandingkan dengan sistem sebelumnya.

Danau yang memiliki jarak 20 km dari Kota Singkawang ini memiliki luas 235 Ha dan berpotensi untuk dikembangkan sebagai sumber air baku bagi Kota Singkawang, khususnya Kelurahan Sagatani. Air baku agar dapat dimanfaatkan sebagai sumber air bersih, jika memenuhi syarat dari kuantitas air dan kualitas air. Tujuan dari penelitian ini adalah untuk mengetahui ketersediaan air dan kualitas air di intake Danau Sarantangan dan sekitarnya. Data primer, meliputi dimensi penampang dan kecepatan aliran di intake sumber air ke Danau Sarantangan, kedalaman Danau Sarantangan, dimensi penampang dan kecepatan aliran di saluran keluar Danau Sarantangan, sampel air di intake sumber air ke Danau Sarantangan, sampel air di Danau Sarantangan dan sampel air di saluran keluar Danau Sarantangan. Data sekunder adalah data curah hujan harian dan data iklim (suhu, kelembaban, kecepatan angin dan lama penyinaran matahari). Debit bulanan ditentukan menggunakan Metode Mock, debit andalan ditentukan menggunakan Metode Hazen. Hasil penelitian menunjukkan bahwa Danau Sarantangan memiliki ketersediaan air sebesar 0,003 m3/detik atau sebesar 259.200 liter/hari dan kualitas air pada Danau Sarantangan memenuhi syarat untuk dapat dikonsumsi dengan melakukan metode peningkatan kualitas air. [EN] Sarantangan Lake is located in Sagatani Village, South Singkawang District. The lake which has a distance of 20 km from Singkawang City has an area of 235 Ha and has the potential to be developed as a source of raw water for Singkawang City, especially Sagatani Village. Raw water is to be used as a source of clean water if it meets the water quantity and quality requirements. This study aimed to determine the availability of water and water quality in the intake of Lake Sarantangan and its surroundings. Primary data, including cross-sectional dimensions and flow velocity in the intake of water sources to Lake Sarantangan, depth of Lake Sarantangan, cross-sectional dimensions and flow velocity in the outlet of Lake Sarantangan, water samples in the intake of water sources to Lake Sarantangan, water samples in Lake Sarantangan and water samples in the outlet of Lake Sarantangan. Secondary data are daily rainfall data and climate data (temperature, humidity, wind speed, and duration of solar irradiation). The monthly debit is determined using the Mock Method, and the mainstay debit is determined using the Hazen Method. The results showed that Lake Sarantangan has a water availability of 0.003 m3/second or 259,200 liters/day and the water quality in Lake Sarantangan is eligible for consumption by improving water quality methods.

Abstract

This report presents the results of research on the management of the Upper Ciliwung River Basin (DAS) in Bogor Regency, which aims to analyze the relationship between upstream area factors and flood events in Jakarta, and provide recommendations for better management. This research was conducted using a qualitative descriptive method through field surveys and literature studies. The results show that the Upper Ciliwung Watershed has diverse physical characteristics, with topography varying from lowlands to steep, and a climate influenced by high rainfall. Land use changes, especially the increase in residential areas, have reduced water absorption capacity and increased surface runoff, which contributes to increased flood risk downstream. In addition, the geological and hydrological conditions of the watershed also affect river flow discharge. Therefore, integrated and sustainable management is needed to maintain ecosystem balance and reduce negative impacts on the environment. Recommendations provided include strengthening land zoning policies, implementing conservation techniques, and increasing community participation in water resource management.

Abstract

This study aims to analyze the effect of work-life balance on employee job satisfaction in the furniture sales industry. Data was collected using a Google Form questionnaire filled out by 75 respondents working in the furniture sales industry. The results of data analysis using SPSS showed that the data were not normally distributed, so non-parametric statistical methods were used for further analysis. Validity tests showed a significant positive correlation between work-life balance and employee job satisfaction (r = 0.574; p < 0.05). Reliability tests showed that the research instrument was reliable with Cronbach's Alpha values for work-life balance variable (α = 0.870), job satisfaction (α = 0.822), and employee loyalty (α = 0.788). Multiple regression analysis showed that work-life balance and job satisfaction significantly affect employee loyalty with R² = 0.672, meaning that 67.2% of the variation in employee loyalty is explained by these two variables. Job satisfaction proved to have a significant positive effect on employee loyalty (β = 0.662; p < 0.05). This study concludes that companies need to pay attention to the work-life balance of employees to improve their job satisfaction and loyalty. Policies such as flexible working hours, employee welfare programs, and mental health support can be effective strategies to achieve these goals.
