Abstract

Particle board is one form of artificial board with the basic material of wood particles (sawdust) using auxiliary materials or adhesives, hot and cold pressed to form sheets that have a certain size according to their function and use. Optimally is to utilize wood waste in the form of sawdust into particleboard and the materials used in this study are rubber wood powder. The quality of the particle board for physical properties, namely the moisture content and density, meets the SNI 03-2105-2006 standard with a maximum value of 14% for moisture content, the results obtained are for A1 (12.17%), A2 (12.07%) , A3 (11.47%). And 0.4 to 0.9 for density standards. with the results obtained in treatment A1 (0.45 gr / cm3), A2 (0.42 gr / cm3), A3 (0.47 gr / cm3). The results on the mechanical properties differ from the physical properties, where the results obtained in the MoR fracture firmness test did not meet the standard with a value of 82 kgf / cm2 SNI 03-2105-2006 while the results obtained were far from the standard, namely the A1 treatment (12.95 Kgf / cm2), A2 (17.69 Kgf / cm2), and A3 (23.26 Kgf / cm2) as well as the flexural strength of MoE. This is caused by several factors, namely the sample in the pressing process is not evenly distributed, which affects the results on mechanical properties, and the test on the sample is too long, causing the temperature and humidity in the room to affect the value at the time of the testPapan partikel adalah salah satu bentuk papan buatan yang menggunakan bahan pembantu atau perekat dengan menggunakan partikel kayu (serbuk grgaji) sebagai bahan dasarnya, dan tekan panas dan dingin sesuai fungsi dan tujuanya untuk membentuk papan dengan ukuran tertentu.kekurangan papan serba kayu dan pemanfaatan kayu yang terbaik adalah dengan memanfaatkan serbuk gergaji berupa serpihan kayu menjadi papan partikel bahan yang digunakan dalam penelitian ini adalah serbuk kayu karet. Kualitas papan partikel dengan sifat fisik (kadar air dan densitas) memenuhi setandar BSN (2006), dan nilai maksimum 14% untuk kadar air hasil yang di dapatkan untuk A1 (12,17 %) , A2 (12,07 %), A3 (11,47 %). Dan 0,4 sampai 0,9 untuk setandar kerapatan. dengan hasil yang di dapatkan pada perlakuan A1 ( 0,45gr/cm3 ), A2 ( 0,42 gr/cm3), A3 ( 0,47 gr/cm3).Hasil pada sifat mekanis berbeda halnya adengan sifat fisis, dimana hasil yang di dapatkan pada uji keteguhan patah MoR tidak memenuhi setandar dengan nilai 82 kgf/cm2 BSN (2006), sedangkan hasil yang didapatkan jauh dari setandar yaitu pada perlakuan A1 ( 12.95 Kgf/cm2 ), A2( 17.69 Kgf/cm2 ), dan A3( 23.26 Kgf/cm2 ) begitu juga pada keteguhan lentur MoE. Ini disebabkan oleh beberapa faktor yaitu sampel dalam prosesi pengepresan kurang merata sehingga mempengaruhi hasil pada sifat mekanis, dan pengujian pada sempel terlalu lama sehingga menyebabkan suhu dan kelembaban pada ruang mempengaruhi nilai pada saat pengujian

Abstract

Tabanio Watershed which is one of 4 (four) large watersheds covering 7 (seven) of 11 (eleven) sub-districts in Tanah Laut Regency, has a very large role in providing water which is characterized by the function of the Tabanio river itself as a source of raw material for the PDAM. . In addition, 57.6% of the food comes from paddy fields and dry fields and 66.10% of the food comes from livestock, both cows and broilers, which support food supply in Tanah Laut Regency. Changes in land use over a period of time have reduced catchment areas and water bodies. The purpose of this study was to determine the environmental carrying capacity based on ecosystem services for water and food providers in the Tabanio watershed in 2010, 2015 and 2020 and to determine changes from 2010 to 2015 and from 2015 to 2020. The carrying capacity of the ecosystem services based on the ecosystem services of water and food providers in the Tabanio watershed in 2010, 2015 and 2020 is dominated by the medium classification and has a steady trend, but there is still a decline in ecosystem services from changes in land cover mainly due to the expansion of plantation land which reached 17,257.93 Ha and settlement expansion of 2,272.20 Ha. In addition, there was a decrease in the area of dry land agriculture which reached 20,200.15 Ha.

Abstract

Pineapple is a special plant that has a sweet and sour taste and has various benefits. Based on where the pineapple grows, the taste will vary. The aim of this research is to determine the protein content of pineapple based on where it grows. This research method is to determine Lowry protein levels using spectrophotometry. The results of this research were measurements of protein levels in peat areas, the protein concentration was 48.14 µg/mL. After conversion by dilution, the volume used resulted in a sample weight of 0.019 grams. When converted to a sampling weight of 80 grams, the sample weight in percent is 0.024%. Meanwhile, when measuring in a mountainous environment, a level of 40.99 µg/mL was obtained, this is equivalent to a sample weight of 0.016 grams, when divided by the sampling weight of 80 grams, a level of 0.021% w/w was obtained. When sampling was carried out in the lowlands, the protein level obtained was 45.39 µg/mL. So the protein obtained is 0.018 grams, when you calculate the % weight per weight you get a level of 0.022%. The conclusion of this research is that the highest protein content is pineapple that grows in a peat environment.
