Abstract

Burflower (Neolamarckia cadamba Miq.) is a fast-growing wood species which has been planted in some community forest on Java Island in recent years. This study aims to examine the surface growth stress of 5-year-old burflower wood from a community forest in Sleman, Yogyakarta. In addition, the axial variation of the surface growth stress within the stem also studied. The strain gauges method was conducted to determine the surface-released strains (SRS) in the stem periphery. The results show that the mean value of longitudinal SRS was -241,58 μɛ (-239 "“ 1.141 μɛ), while tangential SRS was -208,89 μɛ (-564 "“ 18 μɛ). These SRS values were considered low (under 650 μɛ) therefore the burflower wood theoretically has no potential for processing defects. There is no significant difference in SRS value within stem in the axial direction. This result indicates that the SRS measurement for 5-year-old burflower wood can be carried out only in the breast high of standing trees. Keywords: Periphery, processing-defects, strain gauges, strains Abstrak Jabon (Neolamarckia cadamba Miq.) adalah spesies kayu cepat tumbuh yang banyak ditanam di hutan rakyat di Pulau Jawa dalam beberapa tahun terakhir. Penelitian ini bertujuan untuk mempelajari tegangan pertumbuhan permukaan kayu jabon yang berumur 5 tahun dari hutan rakyat di Kabupaten Sleman, Yogyakarta. Selain itu, variasi aksial dari tegangan pertumbuhan dalam satu batang pohon juga dipelajari. Metode strain gauges digunakan untuk menentukan pelepasan regangan permukaan (PRP) pada periferi batang pohon. Hasil penelitian menunjukkan nilai rerata PRP longitudinal yaitu 241,58 μɛ (-239 "“ 1.141 μɛ), sedangkan PRP tangensial sebesar -208,89 μɛ (-564 "“ 18 μɛ). Nilai PRP yang relatif rendah (di bawah 650 μɛ) menunjukkan bahwa kayu jabon secara teori tidak berpotensi mengalami cacat pengolahan. Tidak ditemukan adanya perbedaan signifikan nilai PRP dalam satu pohon pada arah aksial. Hasil ini mengindikasikan bahwa pengukuran PRP pada kayu jabon umur 5 tahun cukup dilakukan pada bagian setinggi dada saja pada saat pohon masih berdiri. Kata Kunci: Cacat pengolahan, periferi, regangan, strain gauges

Abstract

Termite infestations in buildings and plantations cause economic losses. Kirinyuh (Eupatorium odoratum) has the potential to be an insecticide for controlling subterranean termites (Coptotermes curvignathus). The objective of this study was to test the effectiveness of E. odoratum stem extract in inhibiting the activity of C. curvignathus termites and to analyze the optimal concentration of the extract for inhibition termites attack, with parameters termite mortality and test paper weight loss. The study employed a Completely Randomized Design (CRD) with a single treatment variable: extract concentration. E. odoratum stems weighing 150 grams were macerated with 96% ethanol at a 1:8 ratio, then five extract concentrations were prepared: 1%, 2%, 3%, 4%, and 5%. Filter paper was soaked in the extract solution and used as a food substrate for termites. Testing was conducted over a 21-day period, using 50 termites (45 worker termites and 5 soldier termites). The results showed that the yield of E. odoratum stem extract was 7.37%. The average termite mortality ranged from 14.67% to 75.33%, while the average test paper weight loss ranged from 39.88% to 89.48%. The calculated LD50 value at the 3% concentration was 1.733 × 10⁻ ² mg/kg body weight. Keywords : antitermites, biotermiticide, Coptotermes curvignathus, Eupatorium odoratum, lethal dose Abstrak Serangan rayap pada bangunan dan perkebunan menimbulkan kerugian ekonomi. Kirinyuh (Eupatorium odoratum) berpotensi sebagai insektisida pengendali rayap tanah (Coptotermes curvignathus). Tujuan dari penelitian adalah menguji ekstrak batang kirinyuh E. odoratum dalam menghambat aktivitas rayap C. curvignathus dan menganalisis konsentrasi ekstrak yang paling optimal dalam membunuh rayap dengan parameter kematian rayap dan kehilangan berat kertas uji. Penelitian menggunakan Racangan Acak Lengkap (RAL) dengan satu perlakuan yaitu konsentrasi ekstrak. Batang E. odoratum dengan berat 150 gr dimaserasi dengan etanol 96% dengan perbandingan 1:8, kemudian ekstrak dibuat menjadi lima konsentrasi yaitu 1%, 2%, 3%, 4% dan 5%. Kertas saring dicelupkan ke dalam larutan ekstrak dan digunakan untuk substrat makanan rayap. Pengujian dilakukan selama 21 hari dengan jumlah rayap sebanyak 50 ekor rayap (45 rayap pekerja dan 5 rayap prajurit). Hasil penelitian menunjukkan rendemen ekstrak batang E. odoratum sebanyak 7,37%. Nilai rerata kematian rayap sebesar 14.67% - 75.33%.dan rerata kehilangan berat kertas sebesar 39.88% - 89.48%.

Community Perception of Telok Berdiri Ecotourism is one form of public response to the functions and benefits of the mangrove ecosystem, including physical, biological, chemical, economic, and social aspects. One of the ecotourism attractions in Sungai Kupah is the mangrove forest. This study aims to examine the community's perception of Telok Berdiri Ecotourism in Sungai Kupah Village and to analyze the relationship between the level of knowledge, income, and cosmopolitanism with community perceptions in Sungai Kupah Village. This research uses a survey method and is analyzed using Pearson product-moment correlation and descriptive analysis. The community's perception of Telok Berdiri Ecotourism in Sungai Kupah Village tends to be positive, at 60.67%. The knowledge factor has a negative and insignificant relationship with a very weak correlation; the income factor has a positive and insignificant relationship with a very weak correlation; and the cosmopolitanism factor has a positive and significant relationship with a weak correlation. These perceptions can serve as a reference to further engage the community with the mangrove ecosystem.

Anura is one of the natural resources that needs to be preserved, and is a parameter for natural balance. Anura species diversity can be found in the Riam Angan Tembawang Nature Tourism area, Jelimpo District, Landak Regency, but the number of species is unknown. The purpose of this research is to collect data, describe and study various types of anura at that location. The data collection technique is the Visual Encounter Survey (VES) method combined with transect sampling on two types of habitat; aquatic and terrestrial. The data obtained were then analyzed, namely species index (H'), species evenness index (E), relative trapping index (Psi), species comfort index (IS), and analysis of habitat conditions. The results of the study obtained 12 species from 5 families with a total of 176 individuals. The species diversity index value H'=1.97. Evenness Index value for aquatic habitat E=0.77 and terrestrial habitat E=0.95.

Abstract

Birds are wild animals that can be found in almost all places on earth, including in the Dange Aji protected forest. The diversity of bird species in this location is not known with certainty, therefore it is important to carry out research on diurnal bird species in this location in order to obtain data regarding the diversity of diurnal bird species for bird conservation management efforts. The aim of this research is to examine the diversity of diurnal bird species in each land cover in the Protected Forest area in Dange Aji Village. This research was conducted using a survey method with data collection techniques using the point count method combined with line transects.The counting points were made at 6 (six) points in each land cover with a distance between points of 200 m. The data is analyzed and then used to calculate indices of dominance, diversity, similarity, richness and evenness. This research was conducted from July to August 2023. The results of observations carried out in Primary Forest, obtained a diversity index value of H'= 3,12, Agriculture and Shrubs H'= 2,72, Shrubs H'= 1,53 and Forest Secondary H'= 2,80. The diurnal bird species diversity index value in the Protected Forest in Dange Aji Village is H'= 3,30. Species diversity in each land cover is influenced by differences in different vegetation conditions, availability of feed and land cover.
