Turnover can also be defined as the movement of workers out of the organization. Turnover refers to the final reality faced by an organization in the form of the number of employees who leave the organization in a certain period, while the desire of employees to move (turnover intentions) refers to the results of individual evaluations regarding the continuation of relationships with the organization that have not been manifested in definite actions to leave the organization. This study aims to determine the effect of Financial Compensation on Turnover Intention, Knowing the effect of Non-Financial Compensation on Turnover Intention and Knowing the effect of Job Satisfaction on Turnover Intention. In this study, sample selection was carried out using purposive sampling method. The purposive sampling method is a sampling technique with certain considerations. The sample in the study was selected using purposive sampling and obtained 65 samples. Based on the research results, financial compensation has no significant positive effect on the dependent variable, namely Turnover intention (Y), non-financial compensation has no effect on the dependent variable, namely Turnover intention (Y) and Job Satisfaction has no effect on the dependent variable, namely Turnover intention.

Abstract : Orangutan is classified as an endangered species. Forest clearance for a variety of purposes and functions over the region led to the limited habitat for orangutans. Orangutans habitat is fragmented into several regions led to the survival of a population of a species depends on habitat conditions. Performing a nest survey is important to give a deeper understanding of the ecology and help determine the best protective management measures. We provide basic data of orangutan density and orangutan nesting characteristics in protected forest area Sibongkaras village. This study was conducted in April 2019 until June 2019 in protected forest area Sibongkaras village, Pakpak Bharat. Tracking begins with observed the presence of a nest based on a purposive sampling method. And data retrieval was done by line transect method. Data analyzed at Universitas Nahdlatul Ulama Sumatera Utara. Our result showed that the orangutan population density was 0.0072 individuals/km2 or 0.72 individuals/ha. The dominant position of the nest is in a position which is a position I nest close to the main stem of the tree with the nest number 13 (43.3%). Generally, the nest is found at an altitude of  >15 meters with a sum of 27 nests (90%).Abstrak : Orangutan diklasifikasikan sebagai spesies yang terancam punah. Penebangan hutan untuk berbagai tujuan dan fungsi di kawasan tersebut menyebabkan terbatasnya habitat orangutan. Habitat orangutan yang terfragmentasi menjadi beberapa wilayah menyebabkan kelangsungan hidup suatu populasi suatu spesies tergantung pada kondisi habitat. Melakukan survei sarang penting untuk memberikan pemahaman yang lebih dalam tentang ekologi dan membantu menentukan langkah-langkah manajemen perlindungan terbaik. Kami menyediakan data dasar kepadatan orangutan dan karakteristik sarang orangutan di kawasan hutan lindung Desa Sibongkaras. Penelitian ini dilakukan pada bulan April 2019 hingga Juni 2019 di kawasan hutan lindung Desa Sibongkaras, Pakpak Bharat. Pengamatan dimulai dengan mengamati keberadaan sarang berdasarkan metode purposive sampling. Dan pengambilan data dilakukan dengan metode transek garis. Data yang diperoleh di analisis di Universitas Nahdlatul Ulama Sumatera Utara. Hasil Penelitian kami menunjukkan kepadatan populasi orangutan di 0,0072 individuals/km2 atau 0,72 individu / ha. Posisi sarang yang dominan adalah pada posisi sarang yang berada di posisi paling dekat dengan batang utama, dengan jumlah sarang 13 (43,3%). Umumnya sarang ditemukan di ketinggian > 15 meter dengan jumlah 27 sarang (90%).

The human ativities of macroalgae utilization, land conversion, and sea transportation can cause of macroalgae biodiversity decline. The purpose of this study was to analyze the structure and distribution of macroalgae in seagrass ecosystems at South Tabukan District, Sangihe Islands Regency, North Sulawesi. The research locations were at three research stations, i.e. Karurung Beach - Salurang Village, Palareng Beach - Palareng Village and Galoghong Beach - Batuwingkung Village. The study was conducted in November-December 2018 with line transect method sampling and quadrate sampling technique. Macroalgae were 36 species consists of 25 species of Chlorophyta Division, nine (9) species of Rhodophyta Division and two (2) species of Phaeophyta Division. Macroalga Bornetella nitida had Importance Value Index 39.24% that dominated research locations. The Shannon-Wiener biodiversity Index (H’) of macroalgae species at Station I (H': 3.02) was classified as high while Station II (H': 2.86) and Station III (H ': 2.63) were moderate. Overall, macroalgae species diversity at Tabukan Selatang District was high (H’: 3.00).

Validity Testing

This is a report on validity testing of a novel telephone-sampling technique created as a less expensive and less time-consuming survey method. The technique also enables the sampling of both listed and unlisted telephone numbers. Validity coefficients were computed for door-to-door and telephone interview samples of the same population. Chi-square analyses showed that items of the two techniques were similar, suggesting that the telephone-sampling method is valid.
