Abstract

The aim of this study was to find out the effect of Ethephon, an ethylene releasing compound, in a combination with sulfuric acid resin production Pinus merkusii. The tested stimulants were ETRAT; SR4; 20% sulfuric acid; 20% sulfuric acid - Ethephon 2%; 3.3% sulfuric acid – 4.1% Ethephon; and sulfuric acid – 8.3% Ethephon. Trees without stimulant spraying were the controls. The results showed that for daily production, the first-day observation gave the highest value but decreased drastically after second-day observation in a varied degree depent on the stimulants. On the basis of accumulated production, the addition of Ethephon in a high or low level of sulfuric acid concentration exhibited significantly higher resin production compared to that of ETRAT; SR4; and 20% sulfuric acid stimulants as well as control trees. It increased resin production by 98.0-150.6% compared to control trees in class age of VII and increased by 140.9-227.1% in class age of IV stands. Moderate significant correlations (r=0.65) were observed between the values of resin production and tree diameter (controls) as well as between the values of resin production and tree diameter of trees treated by sulfuric acid stimulants (r=0.65-0.82).Keywords : class age, ethylene, quarre, resin production, tree diameter

Abstract

Rayap adalah agen perusak kayu paling agresif dan menyebabkan banyak kerusakan pada perumahan. Pencegahan serangan rayap dapat dihindari dengan menggunakan  bahan pengawet alami berasal dari tumbuhan. Penelitian ini bertujuan (1) mendeteksi senyawa yang terkandung dalam ekstrak daun kumis kucing (Orthosiphon sp.), mengkudu ( Morinda sp.) dan pepaya (Carica sp.) juga menentukan rendemen ekstrak menggunakan pelarut yang berbeda (etanol- toluena, heksana, etil asetat, etanol dan air panas) (2) menguji dan menentukan aktifitas menolak (repellent) yang  diperoleh  dari  setiap  ekstrak  terhadap  serangan  rayap  kayu  kering  (Cryptotermes  sp.). Metabolit sekunder aktif dideteksi dengan reaksi kimia. Larutan ekstrak diteteskan pada kertas saring dan dikeringkan pada suhu 60°C selama 3 jam. Sampel diuji ke rayap selama 4 minggu. Hasil menunjukkan bahwa rendemen ekstrak tertinggi diperoleh dari ekstraksi dengan air panas kumis kucing, mengkudu dan pepaya yaitu : 27, 8%, 26,71% dan 34,06% secara berurutan. Rendemen ekstrak terendah diukur dalam ekstrak larut heksana (kumis kucing : 4,40% dan mengkudu : 4,81%). Dengan reaksi kimia, senyawa aktif dideteksi dalam semua tumbuhan kecuali alkaloid. Alkaloid dideteksi paling banyak dalam ekstrak pepaya. Ekstrak pepaya larut etil asetat menunjukkan  tingkat  kerusakan  terendah  sedangkan  tingkat  mortalitas  rayap  tertinggi  diamati dalam ekstrak mengkudu larut etanol. Ekstrak pepaya larut etil asetat menunjukkan konsistensi aktifitas yang bagus baik terhadap mortalitas rayap maupun pengurangan berat pada bahan yangdiuji sehingga dengan demikian dapat diaplikasikan pada penelitian berikutnya dengan konsentrasi yang lebih tinggi.

Abstract

Tree breeding program has been conducted in Indonesia in order to produce more productive teak trees. Recently, from this program, superior clones (clone source) of teak have been selected for the establishment of the wider plantations. These clones show a good performance on growth characteristics such as stem diameter and tree height. However, it is important to evaluate wood quality of selected superior teak. Physical (heartwood percentage, wood color, basic density, and shrinkage per 1% change in moisture content) and mechanical (static bending strength and compressive strength) properties were investigated for 10-year old of two sources type of teak (superior and conventional) planted in Randublatung, Central Java, Indonesia. There was not significant different between superior and conventional teak was found in all physical and mechanical properties of both teak wood, suggesting that wood properties of both teak are similar at the same age. All trees are in juvenile phase as show by increasing of basic density from pith to bark. Basic density has positively correlation with all mechanical properties measured. It can be said that basic density can be used to estimate mechanical properties.Keywords: conventional teak, mechanical properties, physical properties, superior teak

Abstract

Antitermite activities of leaf hexane extract of cat whiskers (Orthosiphon sp.) leaves, ethyl acetate, and ethanol- toluene extracts of pepaya (Carica sp.) leaves were investigated in several concentrations (1, 5, 10, and 15%, weight based) that be impregnated to filter papers againts the dry-wood termites Cryptotermes sp. After impregnation, filter papers were dried into oven at 60 °C for 3 hours, then were tested to termites for 4 weeks. The results showed that treatment concentration could obtain the highest termites mortality level, no weight loss and the lowest damage level. Ethyl acetate extract of papaya leaves exhibited the highest termites mortality (91.2%) at concentration of 10%. This concentration also showed the lowest weight loss (0%) and the highest antifeedant activity (antifeedant coefficient of 100%). Ethyl acetate extract of papaya leaves exhibited the lowest of LC50 value (7844.20 μg ml-1 ). Antitermitic activity showed a trend more repellent than toxic. Fatty acid such as hexadecanoic acid, linolenic acid, octadecanoic acid and steroid compounds that detected by GC-MS were estimated to play a role as antitermite agents. Thus, the application of ethyl acetate extract of papaya leaves at concentration of 10% was recommended to the next experiment by using solid wood impregnation.

Abstract

Pemberian pakan kambing dengan daun kaliandra menyisakan limbah ranting kaliandra yang belum banyak dimanfaatkan secara optimal. Penelitian ini bertujuan untuk mengetahui pemanfaatan limbah ranting kaliandra sebagai bahan baku pelet untuk energi terbarukan. Penelitian dirancang untuk mengetahui pengaruh berbagai ukuran partikel bahan baku pada kualitas pelet limbah ranting kaliandra (Calliandra calothyrsus). Ukuran partikel bahan yang digunakan adalah 20-40 mesh, 40-60 mesh, dan 60-80 mesh. Proses pembuatan pelet menggunakan tekanan kempa 70 kg/cm2. Kualitas pelet yang diamati adalah sebagai berikut: berat jenis dan sifat proksimat (kadar air, kadar abu, zat mudah menguap, dan karbon terikat) serta nilai kalor. Hasil penelitian menunjukkan pelet limbah ranting kaliandra terbaik dihasilkan dari ukuran partikel 60-80 mesh dengan pemberian tekanan kempa 70 kg/cm2. Pelet yang dihasilkan mempunyai spesifikasi kualitas sebagai berikut nilai berat jenis 1,086; kadar air 10,12%; kadar zat mudah menguap 82,50%; kadar abu 1,21%; karbon terikat 16,25%; dan nilai kalor 4617,20 kal/g. Hasil penelitian ini menunjukkan bahwa pelet limbah ranting kaliandra telah memenuhi standar kualitas pelet menurut SNI 8021-2014 dan DIN 51731. Penelitian ini dapat disimpulkan bahwa pengembangan limbah ranting kaliandra pada peternakan kambing bisa digunakan sebagai bahan baku pelet sebagai sumber energi terbarukan yang berkualitas.
