Abstract

Luas areal dan produksi pala di kepulauan di Sulawesi Utara paling banyak terdapat dikepulauan Sitaro, Talaud dan Sangihe dan untuk daratan di kabupaten Minahasa Utara,Minahasa dan Minahasa Tenggara. Pala yang dihasilkan dari kepulauan dan daratan yang adadi Sulawesi Utara umumnya diperdagangkan dalam bentuk biji dan fuli. Untuk mendapatkanmutu minyak pala yang baik dipengaruhi oleh jenis pala, agroklimat lokasi penanaman, umurpanen dan teknik penyulingan dalam mendapat minyak pala. Penelitian ini bertujuan untukmengetahui rendemen minyak pala serta mengidentifikasi sifat fisiko kimia dari minyak palakepulauan dan daratan di Sulawesi Utara. Penelitian menggunakan metode deskriptif dandilakukan dalam 2 tahap yaitu menyuling pala untuk mendapatkan minyaknya dan minyak hasilpenyulingan diidentifikasi sifat fisiko kimianya. Hasil penelitian menunjukan bahwa rendemenminyak pala kepulauan berkisar 4,89-5,11% dan pala daratan 4,08-5,01%. Komponen kimia α-pinen, β-pinen, limonene, linolool, miristisin pada minyak pala daratan dan kepulauan diSulawesi Utara memiliki presentase yang berbeda. Kadar miristisin dari minyak pala yang adadi Sulawesi Utara kepulauan berkisar 13,43-16,75% dan daratan berkisar 11,52-13,54%. Kadarmiristisin tersebut lebih tinggi dari yang dipersyaratkan SNI 06-238-2006 yaitu minimal 10%.Kata kunci : minyak pala, miristin, fisiko kimia

Abstract

Vegetable oil company produced large amount of fly ash as a solid waste. This waste has to be placed in a special space and this requirement causing problem for the vegetable oil company, such as decreasing of open space and aesthetics value of a place. This study has been aimed to know addition effect of fly ash on paving block quality. This research used variation of fly ash and coarse sand volume, while fine sand and Portland cement volume as a constant value. The result showed that fly ash can be used as filler material of paving block. Sample was analyzed using SNI 03- 0691-1996 procedure and showed highest value of compresisive strength on A1B2 treatment (22.34 Mpa), while the lowest was showed on A3B3 treatment (18.58 MPa). Water absorption values were ranged from 2.41% to 4.48%, and fulfill standart requirement. Based on test result paving block from A1B1, A1B2, A1B3,A2 B1, A2B2 and A2B3 treatment complied quality standart as B grade of paving block (used for parking yard), when A3B2 and A3B3 treatment complied quality standart as C grade of paving block (used for pedestrian base). The best treatment was A1B2 which consisted of (parts) 2 : 8 : 2 of fly ash, sand and Portland cement respectively, with compressive strength value 22.34 MPa and water absorption value 2.60%

Abstract

ABSTRAKPenelitian pembuatan komposit bata beton ringan dari fly ash dan  bottom ash hasil pembakaran batubara di unit boiler pabrik minyak nabati sebagai pengganti agregat pasir, dengan bahan perekat semen Portland telah dilakukan dengan tujuan untuk mendapat komposit bata beton ringan. Bahan limbah batubara ( fly ash dan bottom ash ) diambil dari boiler industri minyak nabati di kota Bitung. Penelitian dilaksanakan dengan membuat prototype benda uji ukuran (100 x 100 x 100) mm dari fly ash dan b ottom ash sebagai variabel bebas dan agregat pasir, semen serta larutan foam agent sebagai variabel konstan. Prototype benda uji di cetak sebanyak 12 buah tiap perlakuan, dilakukan pemeliharaan (curing) selama 28 hari kemudian dilakukan pengamatan dan uji fisik berdasarkan standar yang ada. Hasil pengujian diperoleh komposit yang terbaik A-5 (5 L fly ash tanpa bottom ash ) dan A-7 (2,5 L fly ash dan 2,5 L bottom ash ) dengan nilai kuat tekan rata-rata (19,06 dan 19,15 kg/cm²) dan bobot isi (1160,19 kg/m³ dan 1242,65 kg/m³) serta penyerapan air (21,96 % dan 14,96 %). Nilai kuat tekan dan penyerapan air memenuhi persyaratan bata ringan untuk untuk konstruksi pasangan dinding bangunan rumah.Kata kunci: bata, batubara, beton-ringan, limbah                                                                          ABSTRACTResearch on the manufacture of lightweight concrete brick composites from fly ash and bottom ash coal waste vegetable oil company to replace sand agregate with Portland cement adhesive has been done with the aim to obtain lightweight concrete brick composites which use fly ash and b ottom ash from coal waste. Research begins with the taking of coal waste materials (fly ash and bottom ash) in the vegetable oil industry in Bitung city, then proceed with the preparation of other auxiliary materials and required equipment. The reward was carried out by making prototype (100 x 100 x 100) mm of the test object and the treatments were fly ash and bottom ash while the use of sand aggregate, cement and foam agent solution was constant. Prototype test object printed as much as 12 pieces each tre atment, carried out maintenance for 28 days then conducted observations and physical tests based on existing standards. From test result of prototype of test object, it turns out that some of the best composite treatment A - 5 (5 L fly ash and no bottom ash) and A - 7 (2,5 L fly ash and 2,5 L bottom ash) was obtained with a compressive strength value of (19,06 and 19,15) Kg/cm2 and weight of content (1160,19 Kg/m3 and 1242,65 Kg/m3) respectively with water absorption values (21,96% and 14,96%). Strength and abs orption values fulfill requirement of lightweight concrete for house building wall
