Abstract

Lean Construction atau konstruksi ramping merupakan sebuah metode yang beberapa tahun terakhir digunakan para penyedia jasa konstruksi untuk meminimalkan waste yang terjadi dengan tujuan meningkatkan nilai tambah (value). Dari hasil identifikasi sebelumnya pada proyek Pembangunan Jembatan Sei Alalak Banjarmasin, terdapat 3 faktor penyebab waste yang paling berpengaruh yaitu: cuaca buruk, pengawasan pembuatan beton mulai dari penimbangan berat material hingga batching plan, dan dokumen pengujian. Untuk mengetahui penanganan waste tersebut, maka digunakan beberapa tools yang ada pada lean construction dengan menyebarkan kuisioner kepada para ahli (expert). Dengan menggunakan tools yang ada pada lean construction maka strategi penanganan yang didapatkan yaitu 1. cuaca tidak mendukung: last planner system, increased visualization, first run studies, daily huddle meeting; 2. pengawasan pembuatan beton mulai dari penimbangan berat material sampai dengan batching plant: last planner system, daily huddle meeting, fail-safe quality and safety; 3. dokumen pengujian: last planner system, increased visualization, daily huddle meeting, 5S process.

Abstract

ITK II is an integrated laboratory building construction project currently does not involve identifying hazards, risk assessment, determining risk levels, or comprehensive risk control. The results of observations and interviews by the author show that dangers can arise due to workers' implementation, actions, and unsafe conditions. Based on these conditions, it is necessary to carry out a risk analysis with the aim of knowing what risks may occur, knowing the dominant risk level, and knowing the dominant risk response, as well as providing recommendations for effective risk control on the ITK II Integrated Laboratory Building Construction Project. The approach applied in this research includes a qualitative approach, namely at the survey, observation, interview, and distribution of questionnaire stages, and a quantitative approach is used to assess the probability and impact of risks, sort risks from highest to lowest, categorize risks, and design mitigation. risk.  The severity index method is used to calculate the probability and impact of an event. The calculation is carried out based on responses from respondents using a Likert scale and validated by experts. Then, an analysis of the risk response to the dominant risks is carried out. In the relevance test, the results obtained were 22 relevant variables and 3 irrelevant variables. Furthermore, during the validity test and reliability test, the results of the two tests obtained for each variable were valid and reliable. After that, the risk level was calculated, and 15 dominant sub-risks were obtained with a probability and impact matrix value of 9 in the "high" risk category. Risk responses that can be given are: placing safety signs in the work area, using PPE, increasing signs in each corner of the project, holding short meetings to discuss worker safety aspects regularly before starting work, wearing anti-slip shoes when working in a work environment where there is a risk of slipping, and carrying out regular field supervision.

Abstract

Kota Balikpapan merupakan salah satu kota dengan angka kecelakaan lalu lintas (lakalantas) tinggi. Lakalantas di Kota ini didominasi kalangan usia produktif (Polresta Balikpapan, 2018). Pada Tahun 2017 tercatat jumlah lakalantas di salah satu jalan di Kota Balikpapan yaitu jalan Soekarno Hatta mencapai 47 kasus. Berdasarkan angka lakalantas yang terus meningkat, maka perlu dilakukan tindakan pencegahan. Banyaknya pelanggaran berlalulintas pada anak usia remaja dan usia produktif dikarenakan pada usia tersebut rasa ingin tahu dan ingin mencoba sangat tinggi, sehingga banyak sekali pelanggaran lalu lintas ini dilanggar oleh remaja dan usia produktif. Beberapa pelanggaran ini terjadi akibat pendidikan mengenai disiplin berlalu lintas yang langka dikalangan anak-anak baik di lingkungan keluarga maupun sekolah. Dengan adanya kondisi ini, perlu dilakukan sosialisasi keselamatan pada pengendara pemula kepada siswa di SMK AIRLANGGA Balikpapan. Kegiatan ini dilakukan dengan tujuan agar pengendara pemula memiliki kesadaran dan pengetahuan berkendara dengan baik, aman, serta akan selalu terdorong untuk tertib pada peraturan lalu lintas yang ada. Kegiatan ini dilakukan dengan tiga tahapan meliputi tahap persiapan berupa administrasi, alat dan bahan, serta materi; dilanjutkan dengan tahap pelaksanaan sosialisasi; dan evaluasi. Proses berjalannya kegiatan ini cukup baik terbukti dengan banyaknya jumlah peserta yang hadir dan keaktifan peserta pada saat pelaksanaan sosialisasi.

Abstract

Manggar Baru is one of the sub-districts in East Balikpapan District, Balikpapan City. According to the 2012-2032 RTRW of Balikpapan City, Manggar Baru is planned to become a minapolitan and tourism area based on the geographical conditions which are located along the coast. Optimizing the potential of coastal areas is carried out by developing existing land or open spaces into proper beach tourism and can be enjoyed by residents and visitors. Based on the results of a survey that has been conducted, Kampung Nelayan RT 8 Kelurahan Manggar Baru has unfavorable solid waste conditions. Overcoming this problem regarding waste regulations, several things can be done, namely managing existing waste conditions through the provision of infrastructure such as garbage dumps in front of every house in RT 8 to make it easier to collect and sort waste. Then, conduct outreach to the surrounding community regarding education on waste management based on its type and utilization. One of the uses of waste that can be developed is to use plastic bottles or other plastic waste to make eco bricks. In addition, the results of the ecobrick that has been made can be used as material to build a vertical garden. The garden area can be used to develop toga plants for the local community. Seeing the waste problems that occur in RT 8, it is necessary to empower the community in managing waste. Community empowerment can be carried out using the Asset-Based Community Development (ABCD) approach which first takes inventory of assets owned by the community to be used as resources in waste management. The community empowerment methods that require participation include Rapid Rural Appraisal (RRA), Participatory Rapid Appraisal (PRA), Participatory Learning and Action (PLA) and Participatory Training. It is hoped that some of the solutions described above can be a way out of existing problems and can have an impact on both the surrounding community and the people who come to use these facilities.

Abstract

Analysis of Highest and Best Use of Vacant Land at Soekarno-Hatta Kilo 6.5 Balikpapan City. The use of land as a building or property must be analyzed to get the maximum profit from the building. There is a vacant land located at Jalan Soekarno- Hatta Kilo 6.5 with an area of 9,500 m2 and located in the northern part of Balikpapan City. However, this vacant land is only used as a night market, whereas vacant land has a high probability to be renewed. Highest and Best Use analysis is conducted in order to get the probability of suitable property type based on the highest and best land value. This analysis uses four aspects that must be analyzed, namely physically possible to be established, legally permitted, economically feasible, and has the highest possible productivity. Determination of property alternatives begins with the distribution of questionnaires involving several stakeholders. In the results of the questionnaire, alternative properties were obtained, namely residential properties, hotels and apartments. Physical aspects consist of land location, land shape and size, public facilities and accessibility to the land location. Legal aspect consists of zoning and building code which refers to the regulation of Balikpapan City Regional Spatial Plan and One Map One Data website. Financial aspect consists of investment cost, property income, property expenditure, money flow in and out, and Net Present Value. In the aspect of maximum productivity, it is obtained that the hotel property provides the highest land value of Rp. 36,560,342 from the initial land price of Rp. 5,000,000 and provides a land productivity of 631%. It can be concluded that the hotel property alternative is a suitable property to be built on this land.

Abstract

Currently, in Indonesia the world of construction is growing rapidly, then there is an increasing need for technology to streamline and streamline work in the construction sector. To overcome this, a system called Building Information Modeling (BIM) was created. Compared to conventional methods, the BIM system integrates construction work that can save time and money. To find out the obstacles of contractors in using BIM, this research was conducted to find out the level of understanding of contractors towards BIM and inhibiting factors in implementing BIM. The object of this research is contractors in Balikpapan City, both state-owned and private. By analyzing from various literature and respondents' sources, which make the foundation of this research takes place. In decision making of BIM implementation in Balikpapan City, the results of this research can be considered. The results of the research data analysis and discussion regarding the level of understanding as well as implementation barriers and solutions provided are the results obtained. In implementing the use of BIM, the level of understanding of contractors and practitioners is 0.43 or can be called 43% which means that contractors do not understand BIM. The biggest obstacle in implementing BIM from the analysis of the largest value of 4.4 is the lack of human resources capable of fully operating BIM. Synergizing between all private and state-owned parties to coordinate with each other and provide counseling on the use of BIM in the future is the solution to the obstacles.
