All this infomation above will be`used as main input,instrumental input for developing instructional model that will be able to support thecompetency needed by the Mechanical Engineer that will be held in the second stage ofresearch.Survey in 16 industries producing materials, goods and mechanical engineering service,and 6 (six) States Technical I-Hgher Education in Mechanical Engineering Division hadbeen done in order to gather infomation needed for this research. The (six) StatesTechnical Higher Education in Mechanical Engineering Division were UNSRI, ITB, UI,UGM., ITS, UNHAS. The instmments for survey consist of questiormaire for industriesand for universities. The questionnaire for industry consists of 4 parts, there arerespondent identity, the perception items of basic knowledge competency needed for theprofessional mechanical engineer, the perception of mastering level competency ofMechanical Engineer who works in industries, kind of partnership activities betweenindustry and university. The questionnaire for States Technical Higher Education inMechanical Engineering Division consists of 5 (five) parts, there are respondent identity,the perception of mechanical engineering content to be given in promoting competency,needed for Mechanical Engineer in university, the existing facilities in education, theexisting condition of instructional activities to be handled, kind partnership activitiesbetween industry and university. This research find out : A) From industrial point of view that : (1) The ranking priority of Mechanical Engineer competency, presents from the most important competency were Engineering Planning and Design, Management of Engineering Works, Education and Training, Communication, Professional Engineering Practice Skill and Basic Engineering Knowledge, (2) The ranking mastering level competence of Mechanical Engineer whoworks in industry presents from the lowest level ofmzistcring were Communication,Research Development and Commercialisation, Asset Management, ProjectImplementation and Production ; (3) The ranking of competence needed to be improvedaccording to the industries, presents from the most important competency wereCommunication, Engineering Planning and Design, Education and Training, AssetManagement, Research Development and Commercialisation ; (4) The direction ofmechanical engineering specialist needed to be developed presents from the mostimportant were Energy Conversion & Electric Power, Plant and Piping Engineering,Various Special Industries Machinery Engineering, Automotive Engineering, AgriculturalMachine Engineering ; B) From Higher Education point of view this research find out that2 (1) The competency needed to be improved according to respondent in the highereducation technology was The Professional Ethics and Principles; (2) The competencyneeded to be considered in curriculum development were Communication, EngineeringPlanning and Design, Education and Training, Asset Management, Research.Development and Commercialisation, Professional Ethics and Principles, (3) Almost allhigher education technology in mechanical engineering division ever having activities withindustry ; (4) Almost all higher education technology in mechanical engineering divisionhad done very well the laboratory works ; library facilities and services also in good order; the instructional method and media usage and task to be given to the students were inpoor in variety.Base on the summary above, some suggestions are proposed as follow: __ (l) _In order todevelop instructional model for mechanical engineering division: (a) the ranking priorityof competence needed to be achieved have to be used as the instructional objective , (b) he condition of the mechanical engineering division , such as the characteristics of coursecontent, the characteristics ofthe students, the constraints and strength in the educationinstitution and industries. (2) By knowing the type of collaboration activities betweenuniversity and industry, it can be used as an input for improving a better collaborationwhich can give benefits for both clearly, (3) By knowing the direction of mechanicalengineering specialist needed to be developed _ it can be used as an input for designingspecific instructional task for students in order to increase enrichment in knowledge or forcurriculum development.

"Eksploitasi air tanah dangkal telah menyebabkan penurunan muka air tanah. Penulisan skripsi ini bertujuan memberikan solusi transisi dalam mengurangi ekploitasi air tanah dangkal. Solusi yang ditawarkan yaitu perancangan sumur dalam terpusat disertai sistem perpipaan dengan studi kasus di kawasan perumahan. Metode perancangan sumur dalam terpusat meliputi perancangan sumur dalam menggunakan pompa submersible, serta jaringan distribusi perpipaan dengan metode Hardy-cross. Desain ini kemudian ditinjau kelayakannya dari sisi finansial, sosial, dan lingkungan. Kelayakan finansial meliputi biaya perancangan sumur dalam terpusat, kelayakan sosial berupa peningkatan harga jual properti yang berdampak pada taraf hidup pengguna, dan kelayakan lingkungan meninjau pengaruh penurunan muka air tanah pada kawasan perumahan. Hasil analisa menunjukkan bahwa peningkatan harga jual properti akibat perbandingan sumur dalam terpusat terhadap sumur dangkal sebesar 1,62 kali lebih besar. Penurunan muka air tanah mengakibatkan tersedianya ruang discharge dan recharge. Nilai B/C rasio dari perancangan sumur dalam terpusat adalah 3,05. Secara umum keseluruhan perancangan sumur dalam terpusat layak diterapkan di kawasan perumahan.

The exploitation of shallow ground water has led to the decrease in groundwater. This study aims to offer transition solutions in reducing the exploitation of shallow ground water. Solutions that are proposed consist of the design of centralized deep well equipped with piping system in residential area.

The design method of deep well covers the utilization of submersible pump as well as design of piping distribution system using the Hardy-cross method. The feasibility level of the design is analyzed base on the financial, social, and environmental aspects. The financial analysis deal with the total cost of deep well construction, social feasibility calculate the increasing rate of properties pricing that will directly affect the quality of user’s life, and the environmental feasibility assess the impact of the decrease in groundwater at residential area.

The analysis results show that the increasing rate of property pricing due to the centralized comparison wells in shallow wells is 1.62 times greater, with the decrease itself causes the formation of recharge and discharge areas, and the value of B/C ratio is 3,05. At last, it can be concluded that the design of centralized deep well feasible to be implemented in residential area."

"ABSTRAKKondisi perkerasan jalan di Indonesia sangat dipengaruhi oleh peningkatan suhu dan perendaman air. Kerusakan yang terjadi akibat suhu yang panas dan genangan air merupakan hal yang sudah biasa. Pada penelitian ini, material baru BNA-Rubber diuji setelah dicampurkan pada aspal penetrasi 60/70 untuk mengetahui pengaruh penambahannya terhadap daya tahan akibat suhu dan perendaman. Penelitian dilakukan dengan penambahan BNA-R sebesar 20% dari kadar aspal dan pengujian antara lain adalah dengan uji Marshall, Marshall Immersion, dan juga uji Indirect Tensile Strength dengan alat UMATA. Hasil yang didapat menujukkan bahwa penambahan BNA-R pada campuran aspal memiliki Indeks Kekuatan sisa yang lebih baik ketimbang campuran aspal tanpa BNA-R. Sementara untuk uji Indirect Tensile Strength didapat bahwa hasil Modulus Resilient dari campuran benda uji dengan 20% BNA-R lebih baik ketimbang campuran tanpa menggunakan BNA-R.

ABSTRACTThe condition of road pavement in Indonesia relies deeply upon the increase of temperature and its submersion in water. Heat and puddles of water are usual causes of road damages. This study tests the effects of BNA-Rubber; after being mixed in an asphalt hot-mix, against its vulnerability to an increase in temperature and submersion in water. This study is conducted by applying BNA-R in an asphalt hot mix, as much as 20% of the total asphalt content. This mixture is then tested through a series of tests including Marshall, Marshall Immersion, and the Indirect Tensile Strength by using the UMATA. Results from the test indicates that the addition of BNA-R in an asphalt hot-mix has a better index of retained stability than an asphalt hot-mix without the addition of BNA-R.While the results from the Indirect Tensile Strength test states that the Modulus Resilience of the asphalt hot-mix with the BNA-R is much better than the one without the BNA-R."
