Abstract

Pesatnya pertumbuhan penduduk menyebabkan permintaan energi listrik terus meningkat signifikan setiap tahun, Khususnya di Kalimantan timur yang akan menjadi lokasi pemindahan Ibu Kota Negera (IKN). Berdasarkan estimasi dari Bappenas, pada tahun 2024 diperkirakan sekitar 1,5 juta jiwa penduduk yang akan pindah ke (IKN), hal ini akan meningkatkan kebutuhan energy listrik di kalimantan timur. Disamping pertumbuhan penduduk, pertumbuhan ekonomi dan industri juga akan meningkat, Ibu Kota Negara (IKN) bersama dengan Balikpapan dan Samarinda akan menjadi superhub ekonomi di kawasan timur Indonesia. Menurut Menteri ESDM, pasokan tambahan tenaga listrik yang harus dipersiapkan untuk memenuhi kebutuhan listrik IKN adalah sebesar 1.596 MW sampai dengan tahun 2024, disamping itu tuntutan untuk transisi ke energy terbarukan juga sangat tinggi untuk mengurangi emisi karbon. Hydropower merupakan salah satu energy terbarukan yang dapat diterapkan di kalimantan timur didukung dengan potensi debit Ws Mahakam yang cukup besar rata-rata Q80 1771,41 m3/dtk. Kajian ini akan menganalisis potensi Hydropower di Ws Mahakam, Daerah aliran sungai terbesar di provinsi Kalimantan timur. Dalam kajian ini debit limpasan akan dianalisis dengan menggunakan program bantu SWAT dan penentuan titik potensi Hydropower menggunakan Diversion Algoritm. Karena keterbatasan data hujan, Data hujan global MERRA-2 (Corrected-Precipitation) digunakan sebagai inputan dalam pemodelan debit pada program bantu SWAT. Hasil menunjukkan beberapa titik potensi Hydropower pada DAS Mahakam.

Hydropower merupakan salah satu energi terbarukan yang dapat diterapkan di kalimantan timur didukung dengan potensi debit DAS Mahakam yang cukup besar rata-rata Q80 1771,41 m3/s. Studi ini akan menganalisis potensi hydropower di DAS Mahakam, Daerah aliran sungai terbesar di provinsi Kalimantan timur. Dalam studi ini debit limpasan akan dianalisis dengan menggunakan model hujan-limpasan, SWAT. Data hujan global MERRA-2 (Corrected-Precipitation) digunakan sebagai inputan dalam pemodelan hujan-limpasan. Penentuan titik potensi hydropower menggunakan diversion algorithm. Hasil menunjukkan 111 titik potensi hydropower pada DAS Mahakam dengan kapasitas bervariatif mulai dari 200kW – 5,4MW.

Abstract

Beaches often experience erosion or abrasion problems caused by various factors, such as climate change which triggers rising sea levels, high waves, human activities such as beach reclamation, and infrastructure construction that is not environmentally friendly, triggering erosion on the coast. In the coastal area of the city that supports IKN, which is located in the Balikpapan area, Manggar Beach, also experiences abrasion which causes land to narrow in that area. The abrasion that occurs erodes the coastal area around 7-8 meters every year. To produce environmentally friendly infrastructure, this research carried out the addition of coconut fiber waste components to tetrapod concrete used for breakwater construction. In this research, variations in the addition of coir used were 0%, 1%, 2%, 3%, 4% and 5%. The aim was to find out how much influence the addition of coconut coir waste to the concrete mixture had on the compressive strength, tensile strength and flexural strength of the concrete in tetrapods. and produce concrete that uses coconut fiber waste as an alternative material for tetrapod concrete as breakwater armor. Based on the analysis results, the quality of the concrete was 23 Mpa. This value was determined based on wave generation analysis. In addition, it is known that variations in coconut fiber affect the slump, compressive strength, flexural and split tensile test values of concrete. Based on the slump test results, it was found that the greater the variation of coconut fiber in the concrete, the lower the resulting slump test value. In testing the compressive, flexural and split tensile strength, it was found that the optimal composition for adding coconut fiber was 3%, in this composition the amount of coconut fiber fiber was able to improve the mechanical properties of tetrapod concrete compared to other compositions.

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.
