Abstract

ABSTRACT Some aspects that can be a reference in identifying lemongrass wood include anatomical structure (macro and micro properties) based on the trunk (base, middle and end). The results of research identifying the anatomical properties of lemongrass wood on various parts of the trunk provide conclusions of anatomical structure for the macroscopic structure characteristics of lemongrass wood in general do not differ between the position of the base, middle and end and the terrace and sapwood, namely giving the heartwood color brown, has a striped pattern, a rather smooth texture, a smooth tactile effect, somewhat shiny, has a smell like lemongrass or telon oil, the hardness is rather hard and heavy. The microscopic structural characteristics of lemongrass medang wood in the position of lemongrass medang logs (base, middle and tip) show that in general wood fibers experience an increase in length from pith to leather. Based on testing the quality of wood fiber for pulp and paper use which includes fiber length, Runkle Ratio, Muhlstep Ratio (MR), Felting Power (FP), Flexibility Ratio (FR) and Coefficient of Rigidity (CR) that lemongrass wood fiber is included in quality class III. Quality class III is a class of wood fiber that has tear firmness, rupture resistance and low tensile firmness.   Keywords: macroscopic, microscopic, medang wood, position of the trunk   ABSTRAK Beberapa aspek yang dapat menjadi acuan dalam mengidentifikasi kayu medang sereh ini adalah meliputi struktur anatomi (sifat makro dan mikro) berdasarkan bagian batangnya (pangkal, tengah dan ujung). Hasil penelitian identifikasi sifat anatomi kayu medang sereh pada berbagai bagian batang memberikan kesimpulan struktur anatomi untuk ciri struktur makroskopis kayu medang sereh secara umum tidak berbeda antara posisi pangkal, tengah dan ujung dan bagian teras dan gubalnya yaitu memberikan warna kayu terasnya coklat, mempunyai corak bergaris-garis, tekstur agak halus, kesan raba halus, agak mengkilap, mempunyai bau seperti bau sereh atau minyak telon, kekerasan agak keras dan berat.  Ciri struktur mikroskopis kayu medang sereh secara pada posisi batang kayu medang sereh (pangkal, tengah dan ujung) menunjukkan bahwa secara umum serat kayu mengalami penambahan panjang dari empulur hingga menuju kulit. Berdasarkan pengujian kualitas serat kayu untuk penggunaan pulp dan kertas yang meliputi panjang serat, Runkle Ratio, Muhlstep Ratio (MR), Felting Power (FP), Flexibility Ratio (FR) dan Coeffisien of Rigidity (CR) bahwa serat kayu medang sereh masuk ke dalam kelas mutu III. Kelas mutu III merupakan kelas serat kayu yang memiliki keteguhan sobek, ketahanan pecah dan keteguhan tarik yang rendah.   Kata kunci: medang sereh, posisi batang, makroskopis, mikroskopis

Abstract

ABSTRACT The other properties of medang sereah (Litsea sp.) wood that need to be identified are the chemical properties of wood based on the part (terrace and sapwood) and the position of the trunk (base, middle, and end). The purpose of identifying the nature of this lemongrass medang wood will facilitate the introduction of lemongrass medang wood types with other types of medang wood. In addition, it will facilitate the process of working and the purpose of using these types of wood further according to their characteristics because the identification of wood properties is an initial process in determining the allocation of wood utilization. The levels of holocellulose, alpha-cellulose, hemicellulose in the core have relatively greater levels than the sapwood. The hemicellulose content at the base has a relatively higher value compared to the end and middle of the medang citronella log. The lignin content of the sapwood part has a lower tendency compared to the terrace. The results of the analysis also showed that the wood at the end of the trunk had a fairly high lignin content compared to the base of the trunk. Keywords: Litsea sp., wood position, wood chemical, terrace and sapwood   ABSTRAK Sifat kayu medang sereh lainnya yang perlu diidentifikasi yaitu sifat kimia kayu berdasarkan bagian (teras dan gubal) dan posisi batangnya (pangkal, tengah, dan ujung). Tujuan mengidentifikasi sifat kayu medang sereh ini, maka akan mempermudah dalam pengenalan jenis kayu medang sereh dengan jenis kayu medang lainnya. Selain itu, akan mempermudah proses pengerjaan dan tujuan penggunaan jenis kayu tersebut lebih lanjut sesuai karakteristiknya karena identifikasi sifat kayu merupakan suatu proses awal dalam menentukan alokasi pemanfaatan kayu. Pengujian komponen kimia mengacu pada standar ASTM. Kadar holoselulosa, alpha-selulosa, hemiselulosa bagian teras memiliki kadar relatif lebih besar dibandingkan bagian gubal. Kadar hemiselulosa pada bagian pangkal memiliki nilai yang relatif lebih tinggi daibandingkan bagian  ujung dan tengah batang kayu medang sereh. Kadar lignin bagian gubal memiliki kecenderungan lebih rendah dibandingkan dengan bagian teras. Hasil analisis juga menunjukkan bahwa kayu dibagian ujung batang memiliki kadar lignin yang cukup tinggi dibandingkan bagian pangkal batang.

Abstract

ABSTRACT The diversity of bird species in an area can reflect the integrity of the ecosystem and the biodiversity found within it. The existence of a bird in a habitat is very important in a forest ecosystem, for example, birds play an important role in the process of reproduction of vegetation types in the forest, namely in the process of seed dispersal and pollination. This research on identifying this bird species was carried out in the Bukit Sari Grand Forest Park, Jambi Province, which was carried out in two habitats, namely secondary forest and bushes. Bird observations were carried out using the point count method. The results of the research show that in the Bukit Sari Grand Forest Park there are 13 species of birds from 10 families. In the secondary forest there are 9 species of birds from 8 families, in the bush there are 9 species of birds from 7 families. The highest number of individuals was found in the bush habitat with a total of 81 birds, while in the secondary forest habitat there were 52 individuals. The diversity index value (H'), Margalef species richness (R) and species evenness (E) of birds around the Bukit Sari Grand Forest Park, Jambi Province, respectively are H' 2.3, R is 2.5 and E is 0 .9. There are five dominant bird species at each observation point, namely the alang-alang moth (Centropus bengalensis), gray bentet (Lanius schach), merbah cerucuk (Pycnonotus goiavier), finches (Pycnonotus aurigaster) and yellow-rumped woodpecker (Picus flavinucha). Keywords: bird, Bukit Sari Grand Forest Park, habitat   ABSTRAK Keanekaragaman spesies burung di suatu daerah dapat mencerminkan keutuhan ekosistem dan keanekaragaman hayati yang terdapat di dalamnya. Keberadaan suatu burung disuatu habitat sangat penting dalam ekosistem hutan salah satu contohnya sebagaimana burung berperan penting dalam proses perkembangbiakan spesies vegetasi di dalam hutan yakni dalam proses penyebaran biji dan penyerbukan. Penelitian tentang identifikasi spesies burung ini di laksanakan di Taman Hutan Raya Bukit Sari Provinsi Jambi, yang dilakukan pada dua habitat yaitu hutan sekunder dan semak belukar. Pengamatan burung dilakukan dengan menggunakan metode point count. Hasil penelitian menunjukkan bahwa pada kawasan Taman Hutan Raya Bukit Sari terdapat 13 species burung dari 10 famili.

Abstract

ABSTRACT Indonesia is an agrarian country with very large agricultural products. In addition, agricultural by-products are also produced that are largely unutilized, such as rubber fruit shells and cinnamon bark scrap waste. The two by-products have the potential to be used as alternative biomass fuels, one of which is charcoal briquettes. The use of charcoal briquettes tends to produce a pungent smell. Therefore, cinnamon bark powder can be used to reduce the pungent smell. This has the potential to change the aroma of conventional charcoal briquettes. But this related research is still very limited. Therefore, this research aims to analyze the influence of cinnamon bark powder composition on the characteristics of rubber seed shell charcoal briquettes. Charcoal briquettes from rubber seed shell charcoal material CK (100%) and added cinnamon bark powder CK:KM (80%:20%) were made with the addition of tapioca glue and prepared 5 times. Charcoal briquettes are then tested for their characteristics, including: 1. water content, 2. density, 3. ash content, 4. volatile matter content, 5. fixed carbon content, 6. caloric value, 7. compressive strength, and 8. burning rate. The analysis results show that CK (100%) charcoal briquettes have the characteristics of briquettes with low water content, high density, high ash content, high volatile matter content, low fixed carbon content, low calorific value, high compressive strength and high burning rate compared to CK:KM (80%:20%). Based on the values of these parameters, charcoal briquettes CK:KM (80%:20%) have better quality than CK (100%) on 4 parameters (ash content, volatile matter content, fixed carbon content, caloric value and burning rate).   Keywords: charcoal briquettes, rubber seed shell, characteristics, cinnamon bark powder   ABSTRAK Indonesia merupakan negara agraris dengan hasil pertanian sangat besar. Selain itu, juga dihasilkan produk samping pertanian yang sebagian besar belum dimanfaatkan, seperti cangkang buah karet dan limbah kerokan kayu manis. Dua buah produk samping tersebut, berpotensi dimanfaatkan sebagai bahan bakar alternatif biomassa salah satunya briket arang. Penggunaan briket arang cenderung menghasilkan bau yang menyengat. Oleh karena itu serbuk kayu manis mampu digunakan mengurangi bau menyengat tersebut. Hal ini sangat potensial mengubah aroma briket arang konvensional. Tetapi penelitian terkait ini masih sangat terbatas. Oleh karena itu, penelitian ini bertujuan menganalisis pengaruh komposisi serbuk kulit kayu manis terhadap karakteristik briket arang cangkang biji karet. Briket arang dari bahan arang cangkang biji karet CK (100%) dan tambahan serbuk kulit kayu manis CK:KM (80%:20%) dibuat dengan penambahan perekat tapioka dan disiapkan 5 ulangan. Briket arang kemudian diuji karakteristikya, diantaranya: 1. kadar air, 2. kerapatan, 3. kadar abu, 4. kadar zat menguap, 5. kadar karbon terikat, 6. kalor, 7. keteguhan tekan, dan 8. laju pembakaran. Hasil analisis menunjukkan briket arang CK (100%) memiliki karakter briket dengan kadar air rendah, kerapatan tinggi, kadar abu tinggi, kadar zat menguap tinggi, kadar karbon terikat rendah, kalor rendah, keteguhan tekan tinggi, dan laju pembakaran tinggi dibandingkan briket CK:KM (80%:20%). Berdasarkan nilai parameter-parameter tersebut briket arang CK:KM (80%:20%) memiliki kualitas lebih baik dibandingkan CK (100%) pada 4 parameter (kadar abu, kadar zat menguap, kadar karbon terikat, kalor dan laju pembakaran).   Kata kunci: briket arang, cangkang biji karet, karakteristik, serbuk kulit kayu manis

Abstract

ABSTRACT Land conversion due to human activities, such as clearing forest land for agricultural use, has led to a decline in land quality. This decline is characterized by a deterioration in the physical properties of the soil, reduced water absorption capacity, and increased surface runoff. Land use changes in highland areas generally involve slopes with gradients exceeding 15%. The village of Mukai Pintu is situated in the Siulak Mukai sub-district of Kerinci District. The area has undergone land use changes, where land on steeper slopes has a high potential for erosion and landslides. The objective of this study is to investigate changes in several physical properties of soil resulting from land conversion from forest to agricultural land on slopes with gradients of 25-40% and greater than 40% in Mukai Pintu Village. This study employed a survey method with a purposive sampling approach. The study focused on three land uses: forest, mixed gardens, and fields, as well as two slope classes: 25-40% and greater than 40%. The results of this study indicate that the conversion of forest land into agricultural land (mixed gardens and fields) causes changes in several physical properties of the soil, particularly on slopes with gradients of 25-40% and 40%, including a decrease in soil porosity, soil organic matter, percentage of formed aggregates, aggregate stability, soil permeability, and an increase in soil bulk density. Significant changes in soil physical properties occurred in fallow fields   Keywords: forest conversion, Kerinci, land use, soil physical properties   ABSTRAK Konversi lahan akibat aktivitas manusia dalam membuka lahan hutan menjadi lahan pertanian menyebabkan penurunan kualitas lahan. Penurunan kualitas lahan ditandai dengan penurunan kualitas dari sifat fisika tanah, kemampuan menyerap air, dan meningkatnya aliran permukaan. Perubahan penggunaan lahan pada kawasan dataran tinggi umumnya memiliki kemiringan lereng diatas 15%. Desa Mukai Pintu merupakan salah satu desa yang berada di Kecamatan Siulak Mukai, Kabupaten Kerinci. Daerah tersebut mengalami perubahan penggunaan, yang dimana lahan tersebut digunakan pada kemiringan lereng agak curam memiliki potensi erosi serta longsor yang tinggi. Tujuan penelitian ini adalah mempelajari perubahan beberapa sifat fisika tanah akibat konversi lahan hutan menjadi lahan pertanian pada kelerangan 25-40% dan >40% di Desa Mukai Pintu. Penelitian ini dilakukan dengan metode survey dengan pendekatan purposive sampling. Penelitian ini difokuskan pada tiga penggunaan lahan yaitu hutan, kebun campuran dan tegalan serta pada dua kelas kemiringan lereng yaitu lereng 25-40% dan >40%. Hasil penelitian ini menunjukkan bahwa konversi hutan menjadi lahan pertanian (kebun campuran dan tegalan) menyebabkan perubahan beberapa sifat fisika tanah khususnya pada kemiringan lereng 25-40% dan 40% yaitu penurunan porositas tanah, bahan organik tanah, persentase agregat terbentuk, kemantapan agregat, permeabilitas tanah dan peningkatan bobot volume tanah. Perubahan sifat fisika tanah yang signifikan terjadi pada lahan tegalan.   Kata kunci: Kerinci, konversi hutan, penggunaan lahan, sifat fisik tanah

Abstract

The aim of this research is to make an effort to utilize forestry waste, in the form of harvesting waste of acacia (Acacia mangiumWilld.) and coconut shells (Cocos nucifera L.) into particle boards by considering the evaluation of the value of particle board characteristics, both physical and mechanical characteristics in accordance with standards JIS A 5908-2003.This study used a factorial analysis where the first factor was the composition of the raw material for acacia: coconut (100: 0, 60:40, 50:50, 40:60 and 0:100). While the second factor is the provision of pretreatment on particles (cold soak, hot soak and without immersion).This analysis was carried out in a completely randomized design (CRD) with three repetitions.The results showed that the composition of the raw materials had a significant effect on the value of water content, water absorption, modulus of rupture and modulus of elasticity.The pretreatment had a significant effect on the thickness swelling, water absorption, modulus of rupture and modulus of elasticity. Meanwhile, the interaction of these two factors has a significant effect on the internal bond value, modulus of rupture and modulus of elasticity.Based on the results, it is known that only the density parameters that meet the JIS A 5908-2003 standard, the moisture content and thickness development parameters have not met the standards, while the mechanical characteristics of the particle board have not met the standards.Overall particle board with the composition of acacia raw material: young coconut 60:40 and heat soaking pre-treatment can produce good quality particle board.

Abstract

ABSTRACT Animal activity is an activity carried out by animals consisting of several behaviors. Behavior is animal movements that are influenced by the relationship between the animal and its environment that occurs repeatedly, so that it becomes a characteristic of the animal. During the rehabilitation period, animals experience changes in their habitat and other behavioral changes. This study aims to analyze the stereotypical activity of the Sumatran tiger (Panthera tigris sumatrae) during the rehabilitation period at the Sumatran Tiger Rehabilitation Center which is included in the Appendix I category in CITES with critically endangered status causing (Panthera tigris sumatrae) to be conserved ex-situ. Research on stereotypical activities of Sumatran tigers was conducted at the ARSARI Sumatran Tiger Rehabilitation Center (PR-HSD) in West Sumatra. The object of this research is a male tiger (Putra Singgulung) and a tigress (Ria). The method used is focal animal sampling. The results obtained in a study of the stereotypical activity of two Sumatran tigers in ex-situ habitat at PR-HSD were female Sumatran tigers (35.25%) and male Sumatran tigers (36.21%) (Putra singgulung). The most frequently seen activities were resting behavior (55.88%) in female Sumatran tigers (Ria) and (55.88%) in male Sumatran tigers (Putra singgulung). Research on stereotypical Sumatran tiger activities is expected to become basic data for the conservation management of the Sumatran tiger (Panthera tigris sumatrae) at the Dharmasraya Sumatran Tiger Rehabilitation Center (PR-HSD) ARSARI, West Sumatra.   Keywords: sumatran tiger (panthera tigris sumatae), ex-situ conservation, stereotyping activity   ABSTRAK Aktivitas satwa merupakan kegiatan yang dilakukan oleh satwa terdiri dari beberapa perilaku.
