Abstract

Energy consumption particularly on electrical energy is continuously rising as a result of economical rising and community development. Therefore it needs to be responded about this condition by developing renewable energy utilization which is available. Renewable energy resources are possibly developed in Bali such as solar energy, wind energy, hydropower, sea energy, and biomass. However, one of renewable energy resources that is mostly possible to be developed in Bali is hydropower in micro scale wich is named microhydro. The microhydro works by using water flow which has debit and head. However, it needs an analysis both on technical and financial analysis. Technical analysis is carried out by checking debit and head of the water flow, and then calculates power would be generated, as well as the microhydro equipments such as a suitable choosen of turbine, generator, and control system. In other hand, financial analisis is carried out by estimating cost for construction the microhydro system, then by using Net Present Value (NPV) analysis to check that the system is profitable to be constructed. The result noted that Bali has some potential microhydros or pycohydros that are profitable to be developed both on rivers and irrigations system. Financial analyses show that microhydro systems are profitable to be constructed (NPV is positive) as long as their heads are at least 10 meters, in other side, debit are more affected their generated powers. However, in their implementations, there are some barriers in utilize those water flow resources as microhydro systems, such as those sites were used for other objects for instant as tourism destinations, or for cultures conservation, and the communities have not knew the advantages of microhydro yet therefore it needs socialization to the communities.

Abstract

Filter air menyaring kotoran yang dikandung dalam air dengan cara melewatkannya melaluiberbagai rintangan fisik yang halus, melalui proses kimia atau proses biologi. Metoda filtrasidapat dilakukan dengan menggunakan saringan, absorbsi atau pertukaran ion. Filter dapatmenyaring partikel yang dikandung dalam air hingga ukuran lubang saringan yang dapatdilalui oleh air tersebut. Jenis media filter air hingga yang kini masih banyak digunakan diberbagai industri dan rumah tangga adalah dengan media filter pasir, zeolit, dan karbon aktifkarena konstruksinya sangat sederhana sehingga pembuatannya relatif mudah dan murahserta dapat menghasilkan kualitas air yang memadai untuk keperluan industri dan rumahtangga. Pasir aktif merupakan salah satu media yang digunakan Untuk memenuhi kebutuhanmedia filter. Fungsi Pasir aktif adalah untuk menyaring partikel besar/kecil dalam air sekaligusmenjernihkan air. Pasir aktif ini berwarna hitam dan banyak dipergunakan sebagai penggantipasir silika untuk penyaringan tahap awal. Pengamatan besar penurunan tekanan air dalamfilter dengan media pasir aktif telah dilakukan secara eksperimen. Dengan diketahuinyainformasi mengenai besar penurunan tekanan air ini, maka besar penurunan tekanan dalamsistem pipa bisa diperoleh lebih teliti sehingga pemilihan spesifikasi pompa yang diperlukanmenjadi lebih akurat. Sebelum dilakukan eksperimen, karakteristik penurunan tekanan airdalam filter pasir, dipelajari terdahulu menggunakan metode analisis dimensional denganTeorema PI Buckingham. Penurunan tekanan (????P), diameter tabung filter (D), tinggi pasirdalam filter (H), debit aliran air (Q), kerapatan air (????????) dan kerapatan pasir (????p) merupakanvariabel – variabel yang dimasukkan dalam analisis dimensional. Dari analisis dimensionaldiperoleh bahwa tekanan air dalam filter bergantung pada beberapa variabel seperti debit air,rasio diameter tabung dan tinggi pasir filter (D/H). Eksperimen di laboratorium telah dilakukanuntuk mengetahui hubungan antara variabel-variabel tersebut secara teliti serta mengetahuiformulasi penurunan tekanan air dalam filter pasir aktif. Pengamatan telah dilakukan denganmemvariasikan laju aliran air pada beberapa rasio diameter dan tinggi tabung. Kemudianhasilnya juga dibandingkan dengan catridge filter dengan media pasir aktif yang dijualdipasar. Akhirnya, formulasi penurunan tekanan air (????P) diperoleh sebagai berikut:?P = K . . Q2Kata kunci: Filter air, pasir aktif, penurunan tekananThe water filter is used to filter out impurities contained by passing it through a variety ofsubtle physical obstacles, through chemical processes or biological processes. Filtrationmethod can be done by using a sieve, absorption or ion exchange. The filter can filterparticles contained in the water according to the size of the strainer holes that can be passedby the water. Type of water filter media which is still widely used in various industries andhouseholds is the sand filter media, zeolites, and activated carbon because its construction isvery simple so it is relatively easy and inexpensive manufacturing, can produce sufficientwater quality for industrial and household purposes. Active sand is one of the media used tomeet the needs of the filter media. The function of active sand is to filter out large/smallparticles in the water of water purification. Active sand is black and commonly used as areplacement for silica sand for the initial screening stage. Observations of water pressure dropin the filter with active sand media has done experimentally. By knowing the information aboutthe water pressure drop value, then the value of the pressure drop in the pipe system can beobtained more accurately so that the selection of pumps required specifications become moreaccurate. Before the experiment, the characteristics of the water pressure drop in the filtersand, earlier studied using dimensional analysis with Buckingham PI theorem. Pressure drop(?P), the diameter of the tube filter (D), tall sand in the filter (H), the water flow rate (Q), thedensity of water (??) and density of sand (?p) are the variables included in the dimensionalanalysis. From dimensional analysis shows that the water pressure in the filter depends on several variables such as the flow of water, the ratio of the tube diameter and high sand filter(D / H). Experiments in the laboratory have been conducted to determine the relationshipbetween these variables carefully and know the water pressure drop in the formulation ofactive sand filters. Observations have been made by varying the flow rate of water on somehigh ratio of diameter and tube. Then the results are also compared with cartridge filter withactive sand media sold in the market. Finally, formulations of water pressure drop (?P) isobtained as follows?P = K . . Q2Keywords: Filter the water, the sand is active, the pressure drop

Abstract

Performa otomotif adalah salah satu aspek penting dalam menentukan daya saing suatu produk otomotif. Salah satu performa yang penting adalah kemampuan kendaraan untuk melakukan percepatan, melawan hambatan angin, melawan hambatan rolling, melawan gaya tanjakan dan kemungkinan untuk menarik suatu beban. Gaya yang timbul pada roda penggerak untuk melawan hambatan tersebut disebut dengan gaya dorong atau gaya traksi. Besar kecilnya traksi untuk setiap tingkat gigi serta kecepatan kendaraan yang mampu dicapai dapat dikendalikan dengan mengatur ratio dan tingkat transmisi. Ratio transmisi berpengaruh terhadap besarnya torsi yang dapat ditransmisikan, sedangkan jumlah tingkat kecepatannya berpengaruh terhadap kehalusan (smoothness) proses transmisi dan transformasi daya pada sistem transmisi tersebut. Untuk mencari perbandingan gigi antara tingkat transmisi terendah dan tertinggi adalah dengan cara progresi geometri. Dasar dari penggunaan metode ini adalah untuk mendapatkan ratio dan jumlah tingkat kecepatan gigi transmisi pada daerah kecepatan operasi mesin yang sama sehingga fuel economy pada setiap gigi akan sama. Modifikasi ratio gigi menghasilkan kurva traksi dimana jarak kurva gigi yang berdekatan semakin dekat. Hal ini menunjukkan kehilangan daya waktu pemindahan gigi transmisi semakin kecil, atau dengan kata lain kinerja traksinya semakin baik. Perancangan ratio dengan pemasangan 6 tingkat kecepatan,menghasilkan kurva traksi dengan jarak antara kurva traksi sengat dekat, berarti kinerja traksinya paling baik.
