Abstract

Kebutuhan lahan untuk permukiman di Kota Jayapura meningkat searah dengan pertambahan jumlah penduduknya. Dampak dari pertambahan jumlah penduduk ini adalah munculnya kantong-kantong kegiatan yang tidak saling menunjang, salah satunya permukiman baru yang berkembang di luar perencanaan sehingga terbentuk permukiman kumuh. Tujuan penelitian ini adalah menentukan strategi penataan kawasan permukiman kumuh perkotaan dan pengendalian munculnya kawasan kumuh baru di Kota Jayapura. Penelitian ini menggunakan pendekatan kualitatif deskriptif dan metode SWOT dengan responden dari para pakar (purposive sampling). Hasil analisis menunjukkan bahwa penataan kawasan permukiman kumuh yang dilakukan adalah lewat: sosialisasi peraturan, penegakkan peraturan, monitoring dan evaluasi, peningkatan ekonomi masyarakat pemilik ulayat dan menentukan posisi yang tegas antara pemerintah dan masyarakat hukum adat. Strateginya berada pada kuadran IV (WT) yang artinya meminimumkan semua kelemahan untuk menghadapi setiap ancaman. Untuk pencegahan terbentuknya permukiman kumuh baru, strategi yang diperoleh adalah SO (kuadran I) yaitu memanfaatkan kekuatan internal untuk mengambil keuntungan dari peluang eksternal. Pada aspek internal, terdapat faktor: masyarakat memiliki keinginan untuk memiliki lingkungan huni yang layak serta adanya tokoh masyarakat yang mensosialisasikan tentang lingkungan huni yang layak. Pada aspek eksternal, terdapat faktor: aturan atau undang-undang yang mendukung pencegahan terbentuknya kawasan kumuh baru dan program tahunan pemerintah pada peningkatan infrastruktur dasar perkotaan.

Abstract

The study aims to analyze the amount of carbon monoxide pollutants produced from transportation activities and per unit of vehicle on Taruna Bhakti Street – Kamwolker Perumnas III Street, to model carbon monoxide and determine the factors that influence the amount of carbon monoxide pollutants. Data processing using IBM SPSS 25 application with multiple linear regression analysis method. The average amount of CO pollutants obtained testing at the location point is 25.6 ppm or 29,296.17 μg/Nm³. And the amount of CO emissions per vehicle unit for motorcycles amounted to 725.45 ppm, gasoline cars amounted to 603.90 ppm, and diesel cars amounted to 708.57 ppm. The model obtained for testing location point 1, Y = 53,294 + 0,008 X₁ - 13,482 X₂ - 0,432 X₃ - 0,141 X₄ for location point 2 Y = 17,025 + 00,007 X₁ - 7,264 X₂ - 0,087 X₃ - 0,078X₄. And per unit of vehicles for motorcycles Y = 893,474 + 13,421X₁ - 0,447X₂ -76,970X₃, for gasoline cars Y = 603,320 + 14,862X₁ + 0,146X₂ - 97,282X₃ and for diesel cars Y = 385,146 + 23,483X₁ + 0,131X₂ - 73,392X₃. Factors that affect testing at the location point are the number of vehicles (X₁) and wind speed (X₂). For motorcycle vehicles, the vehicle maintenance factor (X₃), gasoline cars are the age of the vehicle factor (X₁), and diesel cars are the vehicle age factor (X₁).

Abstract

This research involves several PLN substation projects in the Maluku and Papua regions. The subject of this study consisted of 25 respondents, namely 1 Project Manager, HSE Engineer and project supervisor. The questionnaire that has been given is then analyzed using the severity index method. The results of K3 risk identification on 44 risk variable indicators with high variables are found in the categories of product purchase and control, work safety in SMK3 and monitoring standards. The highest level of K3 risk to cost performance in substation construction projects in Maluku and Papua is the specification of the purchase of goods and services, the verification system of purchased goods and services, emergency planning and recovery, and labour health monitoring. The allocation of K3 risk in substation construction projects in Maluku and Papua is the most allocated risk shared between the owner and the contractor. The most K3 risk response is by holding and partially allocating to the owner by transferring. Recommendations for mitigation of K3 risks in substation construction projects in Maluku and Papua are by preparing procedures for work steps/related documents that are jointly supervised between the owner and owner. Then it is necessary to form an organization related to K3 that will be responsible for emergencies, work accidents and monthly reporting to the local Manpower Office.

Abstract

Tami Weir is one of the weirs that has a vital role in human life. Sandtraps have an essential role in the operation of Tami bending. The objective of the evaluation and strategy for holding the Tami Weir sandtrap for irrigation water needs is to know the capacity of the Tami Weir sandtrap, the operation of the Tami Weir sandtrap, and the performance of the Tami Weir sandtrap. The method and technique for collecting data in this research is that data analysis is carried out after all the data has been collected. The results are adjusted to the purpose of writing and presented as conclusions. The results of this research are the capacity of the sandtrap during the flushing period, namely that a sediment volume of 73,134 m3 was obtained with a flushing time of fourteen (14) days. During deposition in mud pockets, the water speed will increase, and the deposition process will begin to decrease; at that time, the sediment will enter the channel. To overcome this situation, the sandtrap must be drained. The performance of the sandtrap at Tami Dam has decreased, where there is much alluvial sediment. The performance of sandtrap at Tami Weir cannot operate correctly due to the large number of sediment deposits, which are as high as the drain gate's threshold, making hydraulic draining impossible

Abstract

There are many landslide points on the Arso-Waris National road, so it is necessary to conduct research on the potential for landslides from the physical and shear strength properties. The analysis method uses Slope/W software from GeoStudio, using the Bishop and Fellenius analysis method. The results of the study on 4 points along the Arso-Waris section, showed that with a decrease in the value of the shear strength parameter, both the cohesion value (average decrease of 69.91%) and the value of the shear angle (average decrease of 92.77%) in the reverse analysis resulted in a decrease in the value of the safety factor score by 71.5% (Bishop Method) and 71.11% (Fellenius Method). The value of the smallest (critical) safety factor is 0,498, located at point 4 KM.105+193 in combination loading, by using Fellenius method. Changes in physical properties and shear strength have the potential to reduce safety factor so that there is potential for landslides.
