Abstract

ABSTRACT Rubber wood is one of the wood species used as furniture raw material. Before processing it into furniture, it needs to be dried first until the moisture content meets the SNI requirements. In this study, drying data for rubber wood with different initial moisture content at several different thicknesses were taken from a furniture company in Central Java and then analyzed descriptively using Microsoft Excel. In the drying process, the company applies a cooling phase in between the heating phases. The results of the data analysis show that drying wood with a thickness of 30 mm takes longer than that with a thickness of 25 mm. On the other hand, in the same initial moisture content range, rubber wood with a thickness of 30 mm has a drying rate that is smaller than the drying rate for wood with a thickness of 25 mm. In the higher moisture content ranges the wood drying rate is greater than rubber wood with a low initial moisture content.   Keywords: cooling phase, drying, moisture content, rubber wood, thickness   ABSTRAK Salah satu jenis kayu yang digunakan sebagai bahan baku furnitur adalah kayu karet. Sebelum diolah menjadi furnitur kayu karet perlu dikeringkan terlebih dahulu sampai kadar airnya memenuhi persyaratan SNI tentang kayu untuk furnitur. Penelitian ini data pengeringan kayu karet dengan kadar air awal berbeda pada beberapa jenis ketebalan berbeda diambil dari perusahaan furnitur di Jawa Tengah dan kemudian diolah secara deskriptif menggunakan microsoft excel. Proses pengeringan di perusahaan tersebut menerapkan fase pendinginan di sela-sela fase pemanasan. Hasil pengolahan data menunjukkan bahwa pengeringan kayu ketebalan 30 mm membutuhkan waktu yang lebih lama dibandingkan ketebalan 25 mm. Sebaliknya, pada rentang kadar air awal yang sama kayu karet dengan ketebalan 30 mm memiliki laju pengeringan yang lebih kecil dibandingkan laju pengeringan kayu ketebalan 25 mm. Rentang kadar air yang lebih tinggi laju pengeringan kayu lebih besar dibandingkan kayu karet dengan kadar air awal yang rendah.   Kata kunci: fase pendinginan,kadar air, kayu karet, ketebalan,  pengeringan

Abstract

ABSTRACT Wood densification is a wood compaction process that aims to increase the density and strength of wood. The application of the densification method to low-quality wood is expected to provide added value to the wood so that it is used by the community. For example, in the type of pulai wood which is included in the IV–V strong class with an average specific gravity of 0.38 g/cm3. Wood densification is affected by wood plasticity, wood plasticization can be done with a softening technique before the wood is processed through pre-treatment such as steaming. The purpose of this study is to analyze the effect of steaming time on the physical and mechanical properties of densified pulai wood (A. scholaris). This study used a Complete Random Design of one factor of steaming time treatment with 5 levels of experiments, namely no treatment/control, steaming time of 30 minutes, 45 minutes, 60 minutes and 75 minutes. Physical and mechanical properties testing is carried out on test samples that have been densified. Physical property testing including moisture content and density refers to the standards JIS Z 2102 (1957) and JIS Z 2103 (1957). The mechanical properties tested are MOR and MOE referring to the JIS Z 2113 (1963) standard. The results showed that the steaming time had an effect on the value of moisture content, density, modulus of elasticity and modulus of rupture. The steaming 30-minute, 45-minute and 60-minute times provide results that are not noticeably different, but are markedly different from the 75-minute and control steaming times (without steaming).   Keywords: densification, pulai wood, steaming   ABSTRAK Densifikasi kayu merupakan suatu proses pemadatan kayu yang bertujuan untuk meningkatkan kerapatan dan kekuatan kayu. Penerapan metode densifikasi terhadap kayu-kayu berkualitas rendah diharapkan dapat memberikan nilai tambah pada kayu tersebut sehingga ragam penggunaannya oleh masyarakat. Misalnya pada jenis kayu pulai yang termasuk dalam kelas kuat IV–V dengan berat jenis rata-rata 0,38 g/cm3. Densifikasi kayu dipengaruhi oleh plastisitas kayu, plastisisasi kayu dapat dilakukan dengan teknik pelunakan sebelum kayu dikempa melalui perlakuan pendahuluan (pre-treatment) seperti pengukusan. Tujuan penelitian ini adalah menganalisis pengaruh waktu pengukusan terhadap sifat fisis dan mekanis kayu pulai (A. scholaris) yang didensifikasi. Penelitian ini menggunakan Rancangan Acak Lengkap satu faktor perlakuan waktu pengukusan dengan 5 taraf percobaan yaitu tanpa perlakuan/kontrol, waktu pengukusan 30 menit, 45 menit, 60 menit dan 75 menit. Pengujian sifat fisis dan mekanis dilakukan terhadap contoh uji yang telah didensifikasi. Pengujian sifat fisis meliputi kadar air dan kerapatan mengacu pada standar JIS Z 2102 (1957) dan JIS Z 2103 (1957). Sifat mekanis yang diuji adalah MOR dan MOE mengacu pada standar JIS Z 2113 (1963). Hasil penelitian menunjukkan waktu pengukusan memberikan pengaruh pada nilai kadar air, kerapatan, modulus of elasticity dan modulus of rupture. Waktu pengukusan 30, 45 dan 60 menit memberikan hasil yang tidak berbeda nyata, namun berbeda nyata dengan waktu pengukusan 75 menit dan kontrol (tanpa pengukusan). Kata kunci: densifikasi, pengukusan, kayu pulai

Abstract

ABSTRACT The plant diversity in Indonesia is often disrupted by the introduction of invasive alien species (IAS), which can have negative impacts on ecosystems and biodiversity. Invasive alien species possess the ability to grow rapidly and compete with native plants, threatening biodiversity in protected areas. This study aims to identify invasive plant species in the Durian Luncuk II Nature Reserve and analyze their impact on the local ecosystem. The research employs a combination of transect and plot line methods with a sampling rate of 2% of the total area. Data collected include plant species, individual counts, habitus, and vegetation analysis using relative density, relative frequency, and the Importance Value Index (IVI). The results show 16 invasive plant species, with Clidemia hirta having the highest IVI (44,21%), dominating nearly all observation plots. The distribution pattern of invasive species is predominantly clumped. These findings indicate that invasive species, particularly C. hirta, have the potential to threaten biodiversity and the integrity of ecosystems in the Durian Luncuk II Nature Reserve, necessitating control and rehabilitation measures to maintain ecosystem balance.   Keywords: Durian Luncuk II Nature Reserve, biodiversity, distribution pattern, invasive alien species   ABSTRAK Keanekaragaman tumbuhan di Indonesia sering terganggu oleh masuknya spesies tumbuhan asing invasif (IAS) yang dapat menyebabkan dampak negatif terhadap ekosistem dan keanekaragaman hayati.

Abstract

ABSTRACT This study aims to examine the variation in soil texture and organic matter content across different canopy density levels in Muhammad Sabki Urban Forest, Jambi City. A purposive sampling method was applied to determine three plots based on canopy density (dense, moderate, sparse). Soil texture was analyzed based on sand, silt, and clay fractions, and organic matter content was obtained from secondary data. The results show that soils in dense and moderate canopy plots were dominated by clay textures and had higher organic matter content, at 7,28% and 6,40% respectively. In contrast, sparse canopy plots exhibited more varied textures and lower organic matter content (5,05%). Higher canopy density tends to increase organic matter accumulation and influence finer soil textures.   Keywords: canopy density, Muhammad Sabki Urban Forest, organic matter, soil texture.   ABSTRAK Penelitian ini bertujuan untuk mengetahui variasi tekstur tanah dan kandungan bahan organik pada berbagai tingkat kerapatan tajuk di Hutan Kota Muhammad Sabki, Kota Jambi. Metode purposive sampling digunakan untuk menentukan tiga plot berdasarkan tingkat kerapatan tajuk (rapat, sedang, jarang). Analisis tekstur dilakukan pada fraksi pasir, debu, dan liat, serta bahan organik dianalisis menggunakan data sekunder. Hasil penelitian menunjukkan bahwa tanah pada kerapatan tajuk rapat dan sedang didominasi oleh tekstur lempung dan memiliki kandungan bahan organik lebih tinggi, masing-masing sebesar 7,28% dan 6,40%. Sementara itu, pada kerapatan tajuk jarang, tekstur tanah bervariasi dan kandungan bahan organik lebih rendah (5,05%). Kerapatan tajuk yang lebih tinggi cenderung meningkatkan akumulasi bahan organik dan mempengaruhi tekstur tanah yang lebih halus.   Kata kunci: bahan organik, Hutan Kota Muhammad Sabki, kerapatan tajuk, tekstur tanah.
