Spectral analysis using Haar wavelet (original signal, denoised signal, residual signal) and source level (SL) for whistle sound of dolphin (Tursiops aduncus) in captivity

This study discussed about Haar wavelet with a view original signal, denoised signal, and residual signal with using fourth whistle sounds of dolphin (Tursiops aduncus). The study was conducted in Safari Park, Cisarua, Bogor Indonesia with 2 dolphins. The results showed differences in results Haar wavelet, this study proves that the Haar wavelet is suitable for the analysis of dolphin sounds, and its have frequency ranged 8-22 kHz. The highest value of the noised signal was smaller than residual signal. The highest of residual signal contained in the second whistle, while the lowest was whistle 1, it showed that the larger the signal denoised result residual signal generated using Haar wavelet. The frequency of source level value ranged 8500 Hz to 11800 Hz, with the highest SL value was 43.9 dB (brown cyrcle). The lowest of the frequency of Source Level (SL) value ranged between 15700 Hz to 17990 Hz, with the lowest SL value was 38.5 dB (brown cyrcle). Whistle 1, 2, 3, and 4 have a different value SL and every SL values obtained in 1,2,3, and 4 have differences noise, it shows the same target but SL value and the sound patterns remain distinct by looking at time duration of whistle sound. Beam pattern from an omni directional sound source (DI= 0 dB, cyan trace) and a directional source following the piston model (DI= 18 dB, black  trace) and beam pattern with 4 types signal have ranged value 70 º-180°, with highest intensity value was 60º

Efek Imunomodulator Ekstrak Etanol Spons Melophlus Sarasinorum Terhadap Aktivitas Fagositosis Sel Makrofag Pada Mencit Jantan Balb/C: Immunomodulatory Effects of Ethanol Extract of Melophlus Sarasinorum Sponge Against Phagocytosis Activity of Macrophage Cells on Balb/C Male Mice

Immunomodulator is an ingredient or drug that can modulate immune system functions and activities. This study was conducted to determine the effect of ethanol extract of Melophlus sarasinorum sponge on macrophage phagocytosis activity. Twenty four male mice balb/c were divided into six groups. The first group received 100 mg/kg of ethanol extract of Melophlus Sarasinorum sponge, the second group received 200 mg/kg of ethanol extract of Melophlus sarasinorum sponge, the third group received 300 mg/kg of ethanol extract of Melophlus Sarasinorum sponge and the fourth group received 400 mg/kg of ethanol extract of Melophlus Sarasinorum sponge. The positive control group received Phyllanthus niruri linn extract (Stimuno®) 0,13 mg/g and the negative control group received NaCMC 0,5%. The extract was orally administered from first day to seventh day. On the eighth day, each of the mice was injected Staphylococcus aureus bacteria (SA) 0.5 mL intraperitoneally. Macrophage cell activity is calculated from smears of peritoneal fluid of mice. Increased doses of ethanol extract of Melophlus sarasinorum sponge increase the amount of macrophage phagocytosis activity that are 25,25% (negative control), 61,5% (positive control), 55,75% (100 mg/kg), 60,75% (200 mg/kg), 62,25% (300 mg/kg) dan 66,25% (400 mg/kg). The results showed that the ethanol extract of Melophlus sarasinorum sponge has the potential as immunomodulator at a doses of 300 mg/kgBB and 400 mg/kg with no significantly different effectiveness with positive control in increasing macrophage cell phagocytosis activity based on the result of post-hoc statistical test of Tukey (sig.> 0,05). &nbsp

Analisis Pertumbuhan Investor Ritel Pada Masa Pandemi Dan Implikasi Pajak Penghasilan Final Atas Penjualan Saham Di Bursa

The Covid-19 pandemic has had a domino effect on the Indonesian economy and stock market. However, in the midst of a sluggish economy, there was a significant increase in the number of retail investors on the Indonesia Stock Exchange. This study aims to analyze the characteristics and level of tax compliance of retail investors who decide to invest in stocks during the pandemic, and to determine the impact of final income tax receipts on stock sales during the pandemic. The research method used is a qualitative method. The research was conducted using primary data and secondary data. Primary data used in the form of open questionnaire data to 120 retail investors. The secondary data used is data on final income tax receipts from the sale of shares from DJP, data on the volume and value of stock trading transactions from IDX, and investor demographic data from KSEI. The results showed that the majority of retail investors who decided to invest in stocks during the pandemic were under 30 years old, had a monthly income of less than IDR 4.8 million, and had a short-term investment type (trading). The level of tax compliance of retail investors who decide to invest in stocks during the pandemic has been formally good but still materially low. The Covid-19 pandemic had a positive impact on increasing final income tax receipts from the sale of shares on the stock exchange. This is due to a significant increase in the volume and value of stock trading transactions at the end of 2020 to early 2021 which shows a sense of investor optimism and is offset by an increase in the number of retail investors.Pandemi Covid-19 memiliki efek domino pada perekonomian dan pasar saham Indonesia. Namun, di tengah lesunya perekonomian, terjadi peningkatan signifikan jumlah investor ritel saham di Bursa Efek Indonesia. Penelitian ini bertujuan untuk menganalisis karakteristik dan tingkat kepatuhan pajak investor ritel yang memutuskan berinvestasi saham pada masa pandemi, serta mengetahui dampak penerimaan pajak penghasilan final atas penjualan saham pada masa pandemi. Metode penelitian yang digunakan adalah metode kualitatif. Penelitian dilakukan menggunakan data primer dan data sekunder. Data primer yang digunakan berupa data kuesioner terbuka terhadap 120 investor ritel. Adapun data sekunder yang digunakan adalah data penerimaan pajak penghasilan final atas penjualan saham dari DJP, data volume dan nilai transaksi perdagangan saham dari BEI, dan data demografi investor dari KSEI. Hasil penelitian menunjukkan bahwa mayoritas investor ritel yang memutuskan berinvestasi saham pada masa pandemi adalah berusia di bawah 30 tahun, memiliki penghasilan bulanan kurang dari Rp 4,8 juta, dan memiliki tipe investasi jangka pendek (trading). Adapun tingkat kepatuhan pajak investor ritel yang memutuskan berinvestasi saham pada masa pandemi sudah baik secara formal namun masih rendah secara material. Masa pandemi Covid-19 berdampak positif pada peningkatan penerimaan pajak penghasilan final atas penjualan saham di bursa. Hal ini disebabkan adanya lonjakan volume dan nilai transaksi perdagangan saham secara signifikan pada akhir tahun 2020 hingga awal 2021 yang menunjukkan rasa optimisme investor serta diimbangi peningkatan jumlah investor ritel.

The Local Innovation Perspective: Development of Mobile-Herbal Service for Indonesia's Mobile Cellular Market

This paper reports the local-innovation perspective for the Indonesian mobile cellular market. Under the local perspective, the innovation opportunity appears when it suit characteristics of the country and the behavior nature of its people such concept is built into realization by making an applications of mobile-herbal (m-herbal) services applications. The service is designed by following the proposed framework, starting from scanning the market demand, defining specific applications, defining the actors, exploration of tacit knowledge of the actors, engineering development, implantation innovation and concurrent innovative development. We used the results of previous market survey emphasizing a need of health-related service for Indonesian market. Herbal remedy was chosen as the focal point of health-related service development since it is well-known indigenous method of treatment by using Indonesian natural ingredients. The service is developed to run on the Android-based smartphone, connects to the database called Indonesian HerbalDB. It consists two main features, i.e. query of herbal remedies and self evaluation assessment. Users of the services may search the names of Indonesian traditional plantation, its local names, and the kind of disease which can be cured. Through the features of self evaluation assessment, users are encouraged to give their personal perception of the herbal remedies, and being the recommendation to other users afterward. Finally, our proposed framework signifies the importance of communications channel among the actors in the mobile cellular facilitating mutual interaction between the multiple actors involved in the mobile herbal development
