Abstract

The social media coverage entitled 75 Years of Indonesia Independence day but we are not yet free shown South Buru hinterland people activities as crossing the Nalbessy river. The safety of user facilities stakes because of breaking up risk, and have fatal consequences washed away by the river current swift. Electronic and print media's rise motivated to examine South Buru hinterland people's facilities need to cross the river. The study aims to trace activities crossing locations and analyzing user potential based on population data. We Presenting roads and bridges history around Liang and Neath Villages in a strip map handling the Namrole - Leksula segment. The method uses Google Earth, structured, and systematic study stages sourced from secondary data. The study results showed that the Nalbessy River coordinate of -3.7628° S and 126.5444° E is Wai Nalbessy III bridge's construction planned location. The Namrole – Leksula segment crosses two villages in South Buru (Liang and Neath). In handling roads until 2019, pavement conditions are still not uniform, consisting of 3 types: Hotmix 7.0 Km, Optional Stockpile of 4.0 Km, and Dirt Road 42.0 Km. The handling of provincial roads has built three bridges out of the 33 bridges plan. Estimated construction cost, the implementation time of the 50 m bridge span Wai Nalbessy III, according to the type of construction, respectively: Rp. 4 billion, four months a symmetrical pedestrian suspension bridge, Rp. 15 billion, ten months of steel frame, and Rp. 20 M, 1 Year for T beam concrete bridge.

Abstract

Penyebaran virus Corona di seluruh dunia telah menimbulkan banyaknya tindakan antisipasi guna meminimalisis penyebaran virus tersebut. Salah satu sifat dari virus corona adalah menempel pada benda. Dengan demikian ketika kita memegang benda yang sudah kena virus corona maka secara otomatis virus tersebut akan berpindah ke tangan orang yang memegangnya. Untuk mencegah terbawanya virus corona maka dianjurkan untuk sering mencuci tangan. Saat ini banyak watafel dan sabun cuci tangan diletakkan di depan rumah, toko ataupun gedung perkantoran dan setiap orang wajib mencuci tangan sebelum masuk kedalamnya. Demikian juga di Politeknik Negeri Ambon telah disediakan wastafel dan sabun cuci tangan di setiap gedung tetapi penggunaannya mengharuskan pengguna memegang tombol pembuka kran dan badan botol agar dapat digunakan. Tangan yang sudah dicuci bisa saja terkena virus kembali ketika memegang tombol kran air untuk menutup kran tersebut. Keadaan tersebut diatas dapat diatasi jika wastafel dan dispenser sabun dibuat otomatis tanpa perlu dipegang oleh pengguna jika ingin menggunakannya. Untuk itu kami memberikan solusi untuk membuat wastafel dan dispenser sabun yang sudah ada di Politeknik Negeri Ambon menjadi alat yang otomatis dapat digunakan tanpa harus bersentuhan dengan pngguna sehingga diharapkan sebaran virus corona dapat diminimalisir. Hasil dari kegiatan ini adalah telah dilakukan Otomatisasi wastafel cuci tangan pada 6 unit wastafel di lingkungan Politeknik Negeri Ambon dan dapat beroperasi dengan baik. Kran putar secara manual tetap dipertahankan pada wastafel untuk mencegah tidak beroperasinya wastafel otomatis ketika sumber listrik mengalami gangguan serta Dispenser sabun otomatis juga telah dipasang pada 6 unit wastafel cuci tangan di lingkungan Politeknik Negeri Ambon dan dapat berfungsi dengan baik

Abstract

Negeri Halong dengan luas wilayah ± 16 KM, memiliki jumlah penduduk mencapai 10.675  jiwa dan bervariasi dalam profesi/pekerjaan dan pendapatan, didalamnya terdapat sekitar 137 orang menekuni profesi sebagai tukang dan pekerja konstruksi untuk menghidupi keluarganya. Para tukang tersebut memiliki ketrampilan yang cukup memadai dalam pelaksanaan pekerjaan konstruksi tetapi tidak memiliki kemampuan untuk menyusun Detailed Estimate/menghitung RAB secara detail dan menentukan durasi waktu pelaksanaan pekerjaan secara pasti, inilah yang menjadi masalah dan perlu dicari solusinya. Tujuan dari pengabdian ini adalah mentransfer ilmu pengetahuan melalui pelatihan agar para tukang dan pekerja konstruksi mampu menyusun Detailed Estimate/membuat RAB secara rinci dan menentukan durasi waktu pelaksanaan pekerjaan secara pasti. Pengabdian dilakukan dengan metode survey awal, pelaksanaan pelatihan dan pendampingan. Hasil pelaksanaan kegiatan disimpulkan bahwa tingkat pencapaian pemahaman para tukang dan pekerja konstruksi adalah diatas 60%. Untuk pendampingan dilakukan selama 3 bulan setelah selesai pelaksanaan kegiatan pengabdian.

Abstract

The construction of the BPKB Service Building of the Maluku Police Traffic Directorate is planned to be completed in 150 calendar days. But in fact the project experienced addendum 1 on November 2, 2020 because at the time of the field inspection the size of the plan drawing did not match the size in the field, so this project experienced a delay of 27.895%. So that delays in project implementation do not recur, the author's goal is to find out cost and time deviations using the result value method. This method uses basic assumptions to make forecasts so that you have enough time to think about how to deal with problems in the future. Data collection techniques carried out are site surveys, observations, and literature. There are two types of variables, namely the independent variable is time and the dependent variable is cost. The data analysis technique used the result value method. The results of the analysis at week 28 of the cost performance index (CPI) < 1 which means the actual costs (ACWP) incurred are greater than the planned work costs (BCWP) so that the project experiences a cost deviation of Rp. 106,014.970.36 from the value a contract of Rp. 21,701,579,200.00 with a percentage of 0.49% and a time performance index (SPI) < 1 which means the project performance is slower than the planned schedule so that the project experiences time deviations for 200 working days with a weight of 6.5845% from the planning schedule 150 working days. Keywords : Earned Value Method, Schedule Performance Index (SPI), Cost Performance Index (CPI)

Abstract

Occupational Safety and Health (K3) is a science for the aticipacion recognizing,  evaluation and control of hazards that arise in the workplace that can have an impact on the welfare and health of workers. The risk of falling is the highest cause of accidents. The use of adequate safety equipment such as guardrails and helmets, as well as the implementation of security procedures such as non-permanent ladders inspection and scaffolding can reduce the risk of accidents.Data analysis was used to calculate the analysis of health and work application in the project "Construction of Hitu Village Primary Hospital". The techniques in data analysis in this study are validity test, reliability test, analytical descriptive, regression analysis test, coefficient of  Determination test, T - test and F test.The results of the analysis show that safety (X1) and health (X2) had a positive effect on work performance from the test results of multiple linear regression analysis from the correlation table or partial correlation, where safety (X1) obtained a value of r = 0.766 with a significance  0.000 <0.05. Health (X2) obtained a value of r = 0.592 with a significant 0.000 <0.05. For the value of the Summary Regression Model Correlation (R) which simultaneously (together) between the variables Health (X1) and Safety (X2), on Work Performance (Y) is r  = 0.767. Among the two aspects of safety and health on the work performance of the Hitu Village Primary Hospital Construction project, the most dominant influencing test results of the partial is the occupational safety aspect of 0.722 or 72.2%.
