Abstract

This study aims to evaluate the quality of tempeh complementation from jackfruit seeds and saga.This research carried out experiments using Complete Randomized Design (CRD) to six treatment that is:NS0 (100% soy as a control); NS1 (90 jackfruit seeds : 10 saga); NS2 (80 jackfruit seeds : 20 saga); NS3(70 jackfruit seeds : 30 saga); NS4 (60 jackfruit seeds : 40 saga) and NS5 (50 jackfruit seeds : 50 saga).The results showed that the complementation of jackfruit seeds and saga significantly affect the moisturecontent, ash content, protein content, fat content, color, aroma, taste and overall assessment and theyhave been conformed tempeh ISO standards, except fat content. Jackfruit seeds and saga complementationNS4 (60 jackfruit seeds : 40 saga) will produce a better tempeh with moisture content 61.53%, ash content0.93%, protein content 28.87%, fat content 5.98%, white color, less-typical tempeh aroma, tastes a goodand overall assessment is less preferred by the panelists.Key words : Jackfruit seeds, saga, tempeh, fermentation, Rhizopus sp.

Abstract

Potensi hutan sebagai penghasil kayu semakin berkurang yang mengakibatkanberkurangnya pasokan kayu sebagai bahan baku. Untuk mengatasi hal tersebut perlu dicarisolusi dimana salah satunya adalah dengan memanfaatkan limbah-limbah yang dihasilkanoleh industri kayu yaitu limbah dari proses pengetaman (shaving) dan serbuk kayugergajian, yang dijadikan bahan baku papan partikel. Kurangnya peralatan dalam membuatproduk papan partikel, menjadi penghambat dalam pengembangan produk tersebut untukdijadikan industri rumah tangga. Penelitian ini mencoba membuat terobosan denganmembuat papan partikel dengan menggunakan peralatan sederhana atau konvensional.Hasil penelitian menunjukan bahwa sifat fisik papan partikel, yaitu kadar air, kerapatan,pengembangan tebal dan daya serap air berturut-turut sebesar 9,18%, 0,50, 22,76% dan39,76%. Sedangkan nilai kadar air, kerapatan, pengembangan tebal dan daya serap airberturut-turut untuk papan partikel dari bahan baku tipe serbuk kayu sebesar 12,14%,0,42, 29,22% dan 45,90%. Sifat keteguhan lentur statis yang meliputi keteguhan patah(MOR) dan kelenturan (MOE) untuk papan partikel dari bahan baku tipe shaving sebesar85,22 kg/cm2 dan 9.284,82 kg/cm2, sedangkan untuk papan partikel dari bahan baku tipeserbuk kayu sebesar 57,42 kg/cm2 dan 4993,14 kg/cm2.Keywords : papan partikel, limbah, kayu, sifat fisik, sifat mekanik

Abstract

ABSTRACT Wood vinegar is the result of condensation and combustion products directly or indirectly. One of the methodes to make wood vinegar is by condensing the smoke products of incomplete combustion (pyrolysis). Materials used for the manufacture of wood vinegar is mahang wood waste from the sawmill industry in the form of sawdust, shavings and slashes. This study aims to determine how much rendement, chemical constituents of  wood  vinegar (phenol, total acid and pH) as well as the colors of the various forms of raw materials. This experiment was carried out using a completely randomited design (CRD) consist of 3 treatments and 5 replications with parameters analyzed were rendement, chemical content and color wood vinegar produced. These results indicate that the form of raw materials affect rendement, chemical content, and color. Sawdust (C1) rendement yield of 14.66 %, phenol content of 15,48 mg/l, total acid of 5,08 %, pH of 2,1 and color of wood vinegar is yellow light brown. Chips (C2) rendement yield of 20,67 %, phenol content of 18,61 mg/l, total acid of 5,78 %, pH of 2,0 and color of wood vinegar is yellow brown. Slashes (C3) rendement yield of 38,98 %, phenol content of 18,80 mg/l, amount 7,72 % total acid, pH of 1,9 and color of wood vinegar is yellow dark brown. Recommended for more efficient utilization of wood waste mahang (Macaranga sp.). As materials are shaped blade of wood vinegar, because it has the highest rendement and good quality wood vinegar. Keywords: Wood Vinegar, Waste, Wood Mahang, Rendement.

Abstract

Pulai wood have economic value, while durable grade is V and powerful class is IV-V and it is low-grade durable, because of that it is needed preservation on Pulai wood. Many Preservation using chemicals that are harmful to environment and humans. In utilizing natural ingredients derived from plants as safer alternative preservatives for environment and humans, it can be renewable for preserving wood from invading organisms wood destroying, especially termites. Materials used as a preservative is liquid smoke empty fruit bunches of oil palm. The aims of this research are to determine termite mortality, retention, weight lose, and water content as well as know the effectiveness of the provision of liquid smoke on Pulai wood preservation against termite attack. The methods used in this research is (RAL), the concentration of liquid smoke oil palm empty fruit bunches of 0%, 10%, 20%, and 30% with 5 replications for three weeks is fed on termites. The results showed that using of preservatives smoke liquid at concentrations of 30% has a value of lose weight on Pulai wood of 0.00g/cm3 and 100% termite mortality. Key word: Liquid Smoke, TKKS, Preservative, Pulai Wood And Coptotermes Curvignathus   Holmgren.

Abstract

Since 2008, tourism department Kuantan Singingi district has let to the local community to manage the Guruh Gemurai waterfall in Desa Kasang Kecamatan Kuantan Mudik Kabupaten Kuantan Singingi. As long as, the local community in managing of the Guruh Gemurai waterfall is not run well. Because of that, the purpose of this research is to find out participation level among people in the community in manage Guruh Gemurai waterfall and to find out the relationship between the condition of economic, social, and culture of the people and participation level. The method of this reseach is Random Sampling. To know the level of participation is used Likert Scale and to know the correlation between participation with social economic and culture is used Chi Square analysis. The result of this study showed the level of community participation in handling Guruh Gemurai waterfall is middle level it is 67,5 %. This case couse, local community just handling in planning and running out. there was a conflict between the local community with tourism department, the characteristic of local community is farmer. Economic, social, and culture factor which have effect to participation level are action in group work tourism, side job and side income in the waterfall area. Social economic factor which dont have effect are education level, duration of recidence around location, number of family member, distance between home and tourism area, knowledge about history of the waterfall, participation in county management, potency of art and culture, main job and main income.
