Analisis Kelayakan Finansial Proyek Pltn Smr di Indonesia dengan Mempertimbangkan Variabel Ketidakpastian

ANALISIS KELAYAKAN FINANSIAL PROYEK PLTN SMR DI INDONESIA DENGAN MEMPERTIMBANGKAN VARIABEL KETIDAKPASTIAN. SMR merupakan salah satu alternatif mengatasi ketergantungan wilayah Luar Jawa Bali terhadap PLTD. Masalah yang sangat krusial dalam proyek PLTN (termasuk SMR) adalah finansial, terkait dengan sifat padat modal pada proyek ini. Selain itu, pada proyek PLTN SMR juga dimungkinkan terjadinya beberapa variabel ketidakpastian. Penelitian ini bertujuan untuk melakukan analisis kelayakan finansial proyek PLTN SMR dengan mengakomodasi kemungkinan terjadinya variabel ketidakpastian tersebut. Metodologi yang digunakan adalah analisis probabilistik yang dilakukan dengan teknik Monte Carlo. Teknik ini mensimulasikan keterkaitan antara variabel-variabel ketidakpastian dengan indikator kelayakan finansial proyek. Hasil penelitian menunjukkan bahwa pada pendekatan probabilistik proyek PLTN SMR dinilai layak pada “most probable value” harga jual listrik sebesar 15 cents/kWh, ditunjukkan dengan rata-rata NPV yang positif (US$ 135.324.004) dan rata-rata kedua nilai IRR yang lebih dari MARR (IRR proyek = 10,65%, IRR Equity = 14,29%, sementara MARR = 10%). Probabilitas ditolaknya proyek PLTN SMR adalah sekitar 20%. Tiga variabel utama yang paling berpengaruh dalam proyek adalah: harga jual listrik, biaya investasi dan tingkat inflasi

Pengaruh Konsentrasi Ekstrak Tanaman Meniran (Phillanthus Niruri L.) dalam Melarutkan Kalsium

Research on the solubility of calcium has been conducted using meniran (phillanthus niruri L.) plant extracts by varying concentrations. This research was conducted by laboratory experiments using meniran plant extracts as samples in dissolving calcium phosphate as a substitute for kidney stones. Meniran is a type of acidic herbal plant extract which contains flavonoids and potassium, so it can dissolve calcium. This study was conducted to determine the most effective concentration of meniran plant extracts from the variation concentration (2%, 4%, 6%, 8% and 10%) in dissolving calcium, and also to determine the effectiveness of this extract compared to Batugin Elixir and distilled water. Determination of the concentration of dissolved calcium in meniran plant extracts was done by a flame photometer. The results showed concentration of 10% of meniran plant extract was effective in dissolving calcium whichwas equal to 46.1 ppm. However, Batugin Elixir was more effective in dissolving calcium with a concentration equal to 58.2 ppm, while distilled water can dissolve the calcium only equal to 4.8 ppm

Ekstraksi Ubi Jalar Ungu (Ipomoea batatas L.) Menggunakan Variasi Pelarut Serta Pemanfaatannya Sebagai Indikator Asam-Basa

Purple sweet potato (ipomoea batatas L.) is one source of carbohydrate. Purple sweet potato contains vitamins and minerals that needed by humans such as vitamin A, vitamin C, calcium, and iron. The sweet potato with purple flesh is widely used as natural dyes which are called anthocyanins. The study aim was to determine a suitable solvent to extract the purple sweet potato. Variation of solvent used namely methanol, methanol acidified with HCl 1% and solvent fractionation (n-hexane, ethyl acetate, and methanol). The extraction phase was divided into two, for flesh and for the skin of the purple sweet potato. The extraction results were then compared with phenolphthalein indicator and a methyl orange on acid-base titration. The results showed that the methanol acidified with HCl 1% provided a more stable color changes in acid-base testing, and the testing of phosphate buffer pH 1-12. Purple sweet potato extracts can be used as an acid-base indicator because it gave similar results with comparative indicators, phenolphthalein, and methyl orange

Does designation as a UNESCO World Heritage Site influence tourist evaluation of a local destination?

The purpose of this study is to explore whether the UNESCO World Heritage Site (WHS) designation affects tourists’ evaluation of the local destination hosting the site, building on a large sample of about 0.8 million tourists who visited Italy over the period 1997-2015. We find that the inscription onto the UNESCO World Heritage List exerts surprisingly a negative effect on the overall evaluation of the destination and also on the evaluation of its artistic assets though the magnitude of the latter is lower. The effect is heterogeneous across visitors, depending on evaluation levels, as well as origin/destinations and demographics. Nonetheless, the presence of multiple WHSs in the same destination tends to increase evaluation suggesting that destination stakeholders with previous experience in dealing with WHS designations are better equipped to manage the complicated relationship between tourism and preservation. Managerial and policy-making implications are discussed
