Abstract

Influence of Solid Waste Degradation To Water Quality Observed from Change of Organic Compound and Nitrogen in Continual Reactor Scale of Laboratory. In river often there are garbage is problems of environment effect of garbage heaping in body irrigate and cause downhillly of him is quality of water, and also influencing at life of territorial water biota, therefore step by step in this research wish to study from early relation between garbage dekomposition which in body irrigate to change of quality irrigate with laboratory scale. Dekomposition is dynamic process and very influence by the existence of good dekomposer of him and amount of, while existence of dekomposer alone very determine by good environmental factors of chemical condition, biology and physics. Is seen from result measurement of value of C/N at garbage that is 14,56. This matter indicate that the the garbage quicker degradation by mikroorganism. At first sampling before passing garbage in earning value of konstanta reaerasi (kr) is 3,585 /day, while at sampling second that is in after passing garbage in earning value of konstanta reaerasi (kr) is 6,467 /day, this matter show the Existence of oxygen cause process oxidize aerobik can take place. Value of konstanta fast of decomposition of BOD5 is 0.7414 and for DO assess konstanta fast of reaction (k) equal to 0.8479. While for Nitrogen assess konstanta fast of reaction (k) equal to 0.5148 and also assess COD have value of konstanta fast of reaction (k) equal to 0.7076. Thus by physics garbage ravelled until day of to-12 that is garbage of terdegradasi become particle / an organic matter. And here in after an organic matter will oxidize with O2 which quite a lot dissolve in water (process aerob) becoming organic acid, further will ravelled to become CO2 and of H2O Abstract in Bahasa Indonesia:Di dalam badan air sering terdapat sampah yang merupakan permasalahan lingkungan akibat dari sampah yang menumpuk di badan air dan berakibat menurunnya kualitas air serta mempengaruhi pada kehidupan biota perairan, oleh karena itu secara bertahap dalam penelitian ini ingin mengkaji dari awal hubungan antara dekomposisi sampah yang ada di badan air terhadap perubahan kualitas air dengan skala laboratorium. Dekomposisi merupakan proses yang dinamis dan sangat dipengaruhi oleh keberadaan dekomposer baik jumlah maupun diversitasnya. Sedangkan keberadaan dekomposer sendiri sangat ditentukan oleh faktor-faktor lingkungan baik kondisi kimia, fisika maupun biologi. Dekomposisi bahan organik menghasilkan bahan organik terlarut yang diukur sebagai COD, BOD, amoniak dan nitrogen organik. Dilihat dari hasil pengukuran nilai C/N pada sampah yaitu 14,56. Hal ini menunjukkan bahwa sampah tersebut lebih cepat terdegradasi oleh mikroorganisme. Pada titik sampling pertama yaitu di titik sebelum melewati sampah di dapat nilai konstanta reaerasi (kr) adalah 3,585 /hari, sedangkan pada titik sampling ke-2 yaitu di titik setelah melewati sampah di dapat nilai konstanta reaerasi (kr) adalah 6,467 /hari, hal ini menunjukkan Adanya oksigen menyebabkan proses oksidasi aerobik dapat berlangsung. Nilai konstanta laju penguraian BOD5 adalah 0.7414 dan untuk DO nilai tetapan laju reaksi (k) sebesar 0.8479. Sedangkan untuk Nitrogen nilai tetapan laju reaksi (k) sebesar 0.5148 serta nilai COD memiliki nilai tetapan laju reaksi (k) sebesar 0.7076. Dari hasil pengamatan selama 24 hari terlihat bahwa sampah organik sudah habis terdegradasi pada hari ke-12 dan seterusnya sampai hari-hari terakhir larutan menjadi bening. Jadi secara fisik sampah terurai sampai hari ke-12 yaitu sampah terdegradasi menjadi partikel/zat organik. Dan selanjutnya zat organik akan dioksidasi dengan O2 yang cukup banyak terlarut dalam air (proses aerob) menjadi asam organik, seterusnya akan terurai menjadi CO2 dan H2O.

Abstract

ABSTRAK Penelitian ini bertujuan untuk mengkaji pengaruh suplementasi temulawak dan Zn- proteinat terhadap konsumsi dan produksi energi susu pada sapi perah laktasi. Materi yang digunakan dalam penelitian ini adalah 16 ekor sapi perah Frisian Holstein, pakan yang terdiri dari hijauan dan konsentrat, suplemen temulawak dan Zn proteinat. Rancangan percobaaan yang digunakan adalah rancangan acak kelompok dengan 4 perlakuan dan 4 ulangan. Pengelompokan dilakukan berdasarkan bulan laktasi dan produksi susu. Empat perlakuan yang diterapkan adalah: T0= Ransum kontrol tanpa penambahan temulawak dan Zn- proteinat, T1= Ransum+2% suplemen temulawak T2= Ransum+40 ppm seng proteinat, T3= Ransum+2%temulawak +40 ppm Zn- proteinat. Hasil penelitian menunjukkan bahawa suplementasi temulawak dan Zn proteinat tidak memberikan pengaruh nyata (P>0,05) terhadap konsumsi energi dan produksi energi susu. Rata-rata konsumsi energi per ekor per hari tiap perlakuan adalah T0=50,10 kkal, T1= 49,62 kkal, T2=48,76 kkal, T3=50,03 kkal. Rata-rata produksi energi susu yaitu T0=9,05 kkal, T1=7,96 kkal, T2=10,19 kkal, T3=9,88 kkal. Meskipun secara statistik tidak berbeda nyata terlihat bahwa suplementasi temulawak cenderung menurunkan produksi energi susu dibanding tanpa suplementasi temulawak (T1 vs T0 dan T3 vs T2), sedangkan suplementasi Zn proteinat berpengaruh meningkatkan produksi energi susu (T2 vs T0 dan T1). Berdasarkan hasil penelitian disimpulkan bahwa penambahan Zn proteinat menghasilkan produksi energi susu yang tertinggi.Kata kunci : temulawak, Zn-proteinat, konsumsi energi, produksi energi.ABSTRACKThis research was aimed to studythe effects of Zn proteinate and Curcuma xanthorrhiza suplementation on feed and energy production. This research used 16 dairy cows Fries Holland, concentrate feed and forages, C. xanthorhiza supplements, and Zn proteinate. Lactating dairy cows were arranged according to randomized block design with 4 treatments and 4 replications. Animal grouping was based on month of lactation and milk production. Four treatments were T0=Feed control without the addition of C. xanthoriza and Zn proteinate, T1= Feed+2% C. xanthorhiza suplement, T2=Feed+ 40 ppm Zn proteinate suplement, T3=Feed+2% C. xanthorhiza suplement+40 ppm Zn proteinate suplement. The results shows that the supplementation of C. xanthorhiza and Zn proteinat not give the real effect (P> 0.05) on energy consumption and energy production of milk. The average of energy consumption T0=50,10 kkal, T1= 49,62 kkal, T2=48,76 kkal, T3=50,03 kkal. The average of energy production T0=9,05 kkal, T1=7,96 kkal, T2=10,19 kkal, T3=9,88 kkal. Although not statistically significantly different look that C. xanthorhiza supplementation tended to reduce energy consumption and the production of milk (T1 vs T0 dan T3 vs T2), whereas Zn ptoteinate suplemention increased the energy production of milk (T2 vs T0 dan T1). It can be concluded that the addition of Zn proteinat produce the best milk energy productionKey word: Curcuma xanthorhiza, Zn proteinate, energy consumption, energy production.

Abstract

The number of sharia-approved companies in the Indonesia Stock Exchange is growing rapidly. It is important to see how the social performance of these companies, using Islamic Social Reporting Index (ISR Index). Financial Distress as an early sign of a company’s failure is also important to study. This study examines the relation between ISR Index and financial distress in list of sharia securities. The control variables apply in this research are SIZE, ROA, CR, WCTR, DER, and RETA. By using a sample of 129 companies from financial statements and annual reports (2014-2018), three models were built with the Modified Altmans Z-Score, Ohlson O-Score and Zmijewski Zm-Score as a proxy of financial distress. Based on ISR index calculation, the theme of products and services has the highest disclosure score. The lowest disclosure score is corporate governance theme. Panel data regression results show that ISR Index affects financial distress in the Modified Altman’s model. It means the higher the ISR index value, the greater the likelihood of companies run into financial distress. Whereas in Ohlson’s and Zmijewski’s model, ISR Index has no effect on financial distress.

Abstract

Crude Palm Oil (CPO) is a commodity in the agricultural sector with the largest contribution to the value of Indonesian exports. Moreover, since 2006, Indonesia has become the largest CPO producer in the world. Therefore, this research attempts to investigate determinants of In­donesia CPO export to main trading partners using Gravity model approach. This study is conducted to analyze the effect of Indonesia’s GDP, GDP of Indonesia’s four main trading partners, distance, the rupiah exchange rate against US dollar and domestic CPO consumption on Indonesian CPO exports. The analysis technique is used in this research is panel data regression using fixed-effect model. The results of this study indicate that not all variables have significant effect on Indonesian CPO exports. Variables such as Indonesia’s GDP and GDP of major trading partners have positive and significant effect, whereas rupiah exchange rate variable and domestic consumption have negative and significant effect on Indonesian CPO export. In addition, in line with Gravity model, variable of distance has negative and significant effect on Indonesian CPO exports.

Abstract : Food Demand Estimation and Alternative Measurement of Regional Poverty Line from Household Survey Data in Indonesia. The purpose of this paper is to analyze food demand behaviour of  Indonesian households and alternative measurement of regional poverty line using Linear Expenditure System (LES).  This paper uses cross section data about household’s expenditure from the 2007 Indonesian Life Family Survey (IFLS,2007), a nationwide survey conducted in 2007. The results show that the Indonesian households have the maximum marginal budget share on rice and the minimum one on fish. From this finding, Indonesian households could be called as “rice lovers” households. Furthermore, results also show that the highest poverty line is for Banten and the lowest poverty line is for  East Kalimantan; the minimum average household expenditure is for  Nusa Tenggara Barat and the maximum is for East Kalimantan.

Abstract

This study aims to analyze the effect of financial performance and macro-economic on Islamic banks' vulnerability in Indonesia from 2014 to 2020. Data were analyzed using the Autoregressive Distributed Lag since their several variables in the economy are dynamic. The results showed that exchange rates and financing are the dominant factors that affect the Islamic banks' vulnerability. Therefore, policymakers tend to identify financial instability and try to avoid the crisis if detected. The Z-score variable in the previous periods (VUL) is another factor that affects Islamic banks' vulnerability
