Abstract

Keuntungan pembuatan papan laminasi antara lain mampu mereduksi cacat-cacat kayu, efisiensi pemanfaatan bahan baku kayu, memiliki nilai estetika dan mudah dalam perawatan Penelitian ini bertujuan untuk mengetahui apakah terdapat kenaikan kelas kuat setelah kayu sengon dibuat menjadi papan laminasi dengan menguji sifat fisika dan mekanikanya. Metode yang digunakan metode eksperimen; Berat labur perekat tidak berpengaruh nyata pada semua pengujian sifat fisika dan mekanika papan laminasi kayu sengon kecuali pada pengujian kadar air dan kerapatan. Semua nilai pengujian sifat fisika papan laminasi kayu sengon telah memenuhi standar SNI 03-2105-2006 dan JAS 234-2007 (JSA 2007) kecuali pada pengujian penyusutan tebal. Sifat mekanika tidak memenuhi standar JAS 234-2007. Berdasarkan nilai berat jenis, MoE dan MoR maka papan laminasi kayu sengon masuk dalam kelas kuat IV. Berdasarkan hal tersebut maka dapat disimpulkan bahwa kayu sengon tidak mengalami peningkatan kekuatan kayu setelah dibuat papan laminasi sehingga hanya dapat digunakan untuk konstruksi bangunan ringan, kerajinan dan meubel.

Abstract

Lamination technology by making laminated boards is a form of increasing the variety of wood products and an effort to overcome the lack of supply of high-quality wood. Laminate board is a form of artificial board made from laminae that are glued together with the help of compression. The characteristics of laminated board are influenced by several factors, including the type of raw material and compression pressure. The aim of this research is to analyze the effect of variations in compression pressure, types of combination and their interactions on the physical and mechanical properties of laminated board products made from a combination of wood and non-wood. The characteristics of laminated board are influenced by several factors, including the type of raw material and felt pressure. Density test results show that the density value has no significant effect on felt pressure, the combination of types and their interactions. Water content testing shows that the type of combination and compression pressure have a significant effect but the interaction has no real effect. The thickness expansion test shows that the compression pressure has a real effect but the type of combination has no real effect. Thickness shrinkage shows that the type of combination has a real effect but compression pressure and interaction do not have a real effect. MoE testing shows that the type of combination has a real effect but the compression pressure and its interaction do not have a real effect. MoR testing shows that the type of combination has a real effect but the compression pressure and its interaction do not have a real effect. There was an increase in the strength class value after combining wood with non-wood from strength class IV to strength class III. All physics test results have met the standards for laminated boards but the mechanics tests have not met the standards

Abstract

The Mandalika Special Economic Zone was developed to encourage regional economic growth, especially Central Lombok Regency, where most of the area is dry land. However, the Human Development Index for this area remains the second lowest in NTB and the poor population remains high, mainly due to low productivity and income from dry land farming. The largest dry land is in Pujut District which is the seat of the Mandalika SEZ. This research aims to analyze the poverty level of food crop farmers in the buffer villages of Mandalika SEZ. The type of research was descriptive, data collection using survey techniques in Sengkol Village, Rembitan Village and Sukadana Village and 45 farmer respondents. The results of the study revealed that the per capita income of food crop farmers was IDR 4,592,057.14/capita/year; equivalent to 352.26 kg of rice/capita/year or equivalent to US$ 0.79/capita/day so that it is classified as poor based on the Sajogyo Poverty Criteria and the World Bank Criteria. The per capita income level is only 15% of the Central Lombok Regency Minimum Wage Standards .
