This study aims to determine the completeness of laboratory facilities and infrastructures, the implementation of the laboratorial practice, to measure the causal factors of laboratorial practice to run, and to be alert of laboratory infrastructure completeness and the implementation of the biology laboratorial practice. Data were collected by observation and questionnaires. The sample in this study were 11 high schools in Banda Aceh, with respondents 11 biology teachers who are responsible for teaching class XI and 99 students of class XI IPA. The data were analyzed using the proportion formula and the product moment answer formula. The study resulted in the findings that: 1) the proportion of completeness of facilities and infrastructure was 66.77% (good). 2) the proportion of laboratorial ptactice implementation was 62.81% (sufficiently implemented). 3) factors of laboratorial procurement, including, inadequate support, inadequate materials, insufficient time allocation, lack of readiness of laboratory assistants in preparing tools and materials, absence of laboratory assistants in several sample schools, and some biology / laboratory assistants in The sample school had never been trained to guide students or to use laboratory equipment. 4) the correlation between the laboratory facilities completeness and infrastructure with laboratorial practice implementation was 0.27 (low). Abstrak. Penelitian ini bertujuan untuk mengetahui kriteria kelengkapan sarana dan prasarana laboratorium, kriteria keterlaksanaan praktikum, mengumpulkan faktor kendala yang menyebabkan kurang berjalannya praktikum, dan untuk mengetahui korelasi antara kelengkapan sarana prasarana laboratorium dengan keterlaksanaan praktikum biologi. Pengumpulan data dilakukan dengan cara observasi dan angket. Sampel dalam penelitian ini adalah 11 SMA di Kota Banda Aceh, dengan responden 11 guru biologi yang mengajar kelas XI dan 99 peserta didik kelas XI IPA. Data dianalisis dengan menggunakan rumus persentase dan rumus korelasi Product moment. Hasil penelitian diketahui bahwa: 1) persentase kelengkapan sarana dan prasarana laboratorium sebesar 66,77% (baik). 2) persentase keterlaksanaan praktikum sebesar 62,81% (cukup terlaksana). 3) faktor kendala pelaksanaan praktikum diantaranya, fasilitas pendukung yang tidak memadai, minimnya kelengkapan bahan praktikum, alokasi waktu untuk praktikum tidak mencukupi, kurangnya kesiapan laboran dalam mempersiapkan alat dan bahan praktikum, tidak adanya laboran di beberapa sekolah sampel, dan sebagian guru biologi/laboran di sekolah sampel belum pernah mengikuti pelatihan mengenai praktikum atau penggunaan alat laboratorium. 4) korelasi antara kelengkapan sarana dan prasarana laboratorium dengan keterlaksanaan praktikum sebesar 0,27 (rendah).
The purpose of this study was to determine the habitat characteristics of the Sumatran Elephant in the Serbajadi District Forest. Data collection by looking at the use of habitat which is characterized by the distribution of faeces found in various habitat units in the home range of the Sumatran Elephant. The method used is observation with a track with a size of 3,600 m which is divided into 20 observation plots with a distance between plots of 100 m. The data obtained in the field were analyzed descriptively and presented in tabular form. The results of this study indicate that the Habitat Characteristics of the Sumatran Elephant in the Serbajadi District Forest chose habitat units with very dense canopy cover (>75%), moderate feed availability (26-50%), rare mineral source trees availability (< 3 trees/plot). availability of sparse scrubbing trees (<3 trees/plot), close to primary forest (0-500 m), low land elevation (0- 400 masl), gentle slope (0-20°), close to water sources (0-250m). Secondary forest/vegetation type and frequency of habitat use based on the findings of faeces that the Sumatran elephant most frequently visited was secondary forest than primary forest because the secondary forest was for feeding activities while the primary forest was used for resting and reproduction.
Burung merupakan satwa liar yang memiliki kemampuan hidup hampir semua tipe habitat, dan mempunyai mobilitas yang tinggi dengan kemampuan adaptasi terhadap berbagai tipe habitat yang luas. Penelitian ini bertujuan untuk menginventarisasi jenis burung yang terdapat di Pulau Tuangku Kecamatan Pulau Banyak Barat Kabupaten Aceh Singkil. Pengumpulan data dilakukan dengan metode observasi lapangan (field method) menggunakan teknik Line Transect. Lokasi penelitian terbagi menjadi tiga stasiun. Stasiun I (kawasan pemukiman), Stasiun II (kawasan pantai) dan Stasiun III (kawasan hutan) dengan masing-masing stasiun terdapat 5 garis transek. Data dianalisis secara deskriptif yang meliputi deskripsi burung, gambar dan hierarki taksonomi. Pengumpulan data lapangan dilakukan pada tanggal 11 sampai dengan 16 Oktober 2019. Berdasarkan hasil penelitian yang telah dilakukan, ditemukan sebanyak 24 jenis burung yang diklasifikasikan ke dalam 7 ordo dan 18 familia. Jumlah spesies burung yang diamati pada stasiun I (pemukiman) ditemukan 13 jenis burung dengan jumlah total 394 individu, pada stasiun II (pantai) ditemukan 14 jenis burung dengan jumlah total 1170 individu, dan stasiun III (hutan) ditemukan 17 jenis burung dengan jumlah total 432 individu. Jadi, jumlah burung secara keseluruhan yang ditemukan di Pulau Tuangku Kecamatan Pulau Banyak Barat Kabupaten Aceh Singkil adalah 1996
The increase of human activity around forest area causes noise anthropogenic effect to animals. This long-term effect can lead to decrease behavior and impact on species composition and inter-species interactions. Sumatran Elephants are classified as endangered animal. This study aims to determine the effect of noise on the Sumatran elephant’s anti-predator behavior and the difference in behavioral response based on the difference noise exposure time. The observation was conducted to Sumatran Elephants in Elephant Conservation Center Saree, Aceh Besar District. Observation method was animal focal sampling technique. The data was analyzed using the chi square test with a significant level of 5%. Based on the results of the chi-square test, the value of sig is 0.000 or smaller than 0.05, indicate that there is an effect of noise toward anti-predator behavior. The observed Sumatran elephants also look more responsive to the noise that is sounded in the morning. Noise can interfere with prey perceptions of predators and correlate with increased energy use.
