Abstract

Downstream part of the watershed is an area of lowland Sekampung with +3.00 to +4.00 elevation above sea level. Area located between the border regions of South Lampung regency and East Lampung. Originally this area was flooded reservoir area, the Swamp Sragi and surrounding areas, but along with the development of this area is used as a residential area, pertaniandan pond area for the people around the area. Padatahun 2002 River Way Sekampung experience overflow caused flooding in downstream areas which suffered losses of up to 38 billion rupiahIn this study analyzed the incidence of flooding that may occur based on rainfall data available. Based on the results of the input stream and cross sectional design flood discharge is seen that when the flood began when the river reaches flood discharge Q50-year anniversary.In this study flood control analysis performed on the three methods are: the construction of levees, making retention ponds and dredge rivers. The third input method results in HEC RAS 3.1.3 shows that building levees to reduce flooding by 32%, on a flood retention pond can be reduced up to 45% and normalization of the river is only able to reduce flooding by 20%. Most effective flood management recommendation is to build two retention ponds and technical cost reduction by flooding.

Abstract

Penelitian ini bertujuan untuk meningkatkan mutu beton dengan waktu produksi yang cepat. Bahan campuran berupa serbuk kaca digunakan sebagai filler (bahan pengisi) dengan variasi 1%, 2%, 3%, 4%, 5% dan 6% untuk menentukan kadar filler serbuk kaca optimum dan didapat kadar optimum sebesar 3%, kemudian proporsinya dibuat sebagai benda uji untuk pengujian lanjutan dengan curing air panas. Digunakan data sekunder berupa substitusi pasir besi optimum sebanyak 10% dan curing air panas optimum pada suhu 40o C selama 4 jam. Curing air panas dapat mempercepat proses pematangan benda uji yang ditunjukkan dengan kuat tekan rata-rata sebesar 26,69 kg/cm2 saat benda uji berumur 6 jam. Namun, kuat tekan rata-rata di umur lainnya lebih rendah jika dibandingkan dengan benda uji tanpa curing air panas. Kuat tekan rata-rata benda uji dengan curing air panas saat berumur 1 hari sebesar 93,75 kg/cm2 (pengaruh penurunannya -22,58%), umur 3 hari sebesar 129,04 kg/cm2 (pengaruh penurunannya -39,30%), umur 7 hari sebesar 177,56 kg/cm2 (pengaruh penurunannya -41,70%) dan umur 28 hari sebesar 304,71 kg/cm2 (pengaruh penurunannya -10,47%). Selain itu, didapat pula hasil rata-rata kuat tarik belah sebesar 17,83 kg/cm2 dan penyerapan air sebesar 2,48%.

Abstract

Energy needs are increasing, while the energy sources used so far have come from petroleum, natural gas and coal (fossil fuels) which are non-renewable and the amount always decreases from time to time. Energy sources derived from renewable fuels are a solution to this problem. One type of product from renewable energy sources derived from vegetable oil is biodiesel (methyl ester). Biodiesel is a monoalkyl ester of long chain fatty acids contained in vegetable oils or animal fats for use as diesel engine fuel. The implementation stage of this activity begins with the preparation of raw materials in the form of preparation of used cooking oil and filtering. The second stage is dissolving caustic soda (2-3 g) into methanol liquid (5:1 methanol water). The third stage is mixing the oil with a solution of methanol and caustic soda into a bottle and allowed to stand for 24 hours, this stage aims to separate the glycerol content in the oil. The fourth step is to separate the oil with solid glycerol and transfer it to an empty container to be mixed with warm water, this aims to remove excess methanol liquid in the oil, let stand for 24 hours. The last step is to separate the oil from the mixing water. From the results of this experiment, a ready-to-use biodiesel liquid was obtained.

Abstract

West Tulang Bawang Regency is a region experiencing rapid development across various sectors, which has led to increased population mobility and a growing demand for adequate transportation systems. One of the public transportation services operating in this area is the DAMRI public transport on the Daya Murni – Unit 2 route. However, limitations in the number of vehicles and operating hours indicate the need for an evaluation of the quality of service provided. This study aims to analyze users’ perceptions of the DAMRI public transportation service based on the indicators of Safety (security and safety), Comfort, Accessibility, Reliability, Cost affordability, Efficiency of service, and overall user satisfaction, as well as to evaluate service quality across all aspects. The research method employed is quantitative descriptive analysis using a survey approach, with data collected through the distribution of questionnaires to 100 respondents, determined using the Slovin formula. Secondary data were obtained from Perum DAMRI and related institutions. The research instrument utilized a five-point Likert scale, and the results of the analysis were classified using class interval methods. The results of the study indicate that users’ perceptions of the seven indicators show average scores ranging from 3,98 to 4,03 which fall into the “good” category. Furthermore, the overall quality of public transportation services based on all aspects achieved a total average score of 87,93 also classified as “good”. These findings demonstrate that the service quality of the DAMRI public transportation on the Daya Murni – Unit 2 route, based on users’ perceptions, is in the good category.
