HAYATI Journal of Biosciences , 2012,
Abstract: In previous studies, Zingiber officinale, Piper retrofractum, and the combination showed cytotoxic activity, induced apoptosis, and p53 expression of HeLa, T47D, and MCF-7 cell lines. This study was conducted to investigate the cytotoxic and apoptotic activity of Zingiber officinale (ZO), Piper retrofractum (PR), and the combination as well as their effect to p53 expression on Myeloma and WiDr cells. The powder of ZO, PR, and ZO + PR combination (1:1) were macerated with 96% ethanol for 3 x 24 hours. MTT cytotoxic assay was performed on Myeloma and WiDr cell lines. Apoptotic cells were stained with ethidium bromide and acridine orange. Imunohistochemical expression of p53 was examined on Myeloma and WiDr cell lines. Doxorubicin was used as positive control in all assays. Results showed that ZO, PR, and ZO + PR combination had cytotoxic activity on Myeloma cells with IC50 of 28, 36, and 55 mg/ml respectively and WiDr cell lines with IC50 of 74, 158, and 64 mg/ml respectively, induced apoptotic activity, and increased p53 expression on Myeloma and WiDr cells. These results suggest that ZO, PR, and their combination induced Myeloma and WiDr cells in apoptosis through p53 expression.

AL-MASRAF : JURNAL LEMBAGA KEUANGAN DAN PERBANKAN , 2016,
Abstract: This study uses data from the survey IFLS-4 (Indonesia Family Live Sur-veys-wave 4) to analyze the impact of competition between lenders on cli-ent behaviour. IFLS-4 contains data on self-reported habits of community residents (312 community) decision to access to Islamic Micro Finance Institu-tion (Islamic MFI), named Baitul Maal wat Tamwil (BMT). This data con-tains specific type of BMT’s location which could be accessed by commu-nity, with variously geographical distances. This data also is enriched by the presence of another type of conventional MFI. This study found that in-creased competition suggesting clients to change their behaviour. The pres-ence of conventional MFI and theirs proximity as indicator of competition, very instrumental in determining access to BMT. Interesting finding, for reli-gious type borrowers, they tend to sustain their access to BMT whose more far geographical distance, even conventional MFI presence inside their vil-lage. Thus, this study suggests that the expansion of financial inclusion stra-tegy of Islamic MFI should also be specifically determined by behaviour of and the BMT’s location among the community.
ULAMAS AND HIS INFLUENCE ON CONFLICT RESOLUTION : THE ROLE OF HETEROGENEITY IN COMMUNITIES STRUCTURE

MAQDIS : JURNAL KAJIAN EKONOMI ISLAM , 2016,
Abstract: This paper examines some concepts regarding religion and conflict, more specifically, the role of Islamic religious leaders in the conflict resolution. In many Muslim countries, Islamic religious leaders play significant roles, not only in the religious realm, but also in the social, cultural, and even political realm. In contrast, the social environment will also determine the level of quality of religious leader’s influence in the form of obedience from citizens over the handling of (resolution) social problems in general and specifically conflict. In the heterogeneous socio-economic structure community realizing those are becoming a major challenge. This article examines the relationship between socio-economic structure of the community with the conflict resolution through the role of the local informal leader, in this case religious leaders (ulama). Data analysis was performed using a combination of SUSENAS and PODES provided by BPS, the unit of analysis based communities around 70,000 villages which aggregated at about 480 districts/cities level of 33 provinces in Indonesia in 2011. At initial stage, we creating specific ulama’s quality measurement, named Indek Kualitas Pengaruh Ulama. Then, because of abundance of zero conflict cases and data overdispersion, we analyze this index relation with socio-economic communities structure through ZIP (Zero-Inflated Poisson) regression. This study found that "stable" socio-economic structure of the communities are determine the ulama’s quality. On the one hand, worsening community social cohesion represented by the high polarization index, tend to erode the ulama’s role (influence) especially in resolving conflict. Conversely, a low polarization index, boosted the confidence level (general trust) to the role of ulama.
SHARIAH FINANCING FOR FARMERS POVERTY REDUCTION
DAVY HENDRI
JEBI (JURNAL EKONOMI DAN BISNIS ISLAM) , 2016,
Abstract: The agricultural’s sector issues remains important, both from strategic and pragmatic sides. From the strategic side, the contribution to GDP and labor absorption in this sector is still significant. While at the pragmatic side, contrary to earlier, the poverty rate of economic actors at the sector did not experience significant improvement. Farmer’s poverty alleviation efforts, as if to see a thick wall. In the era of oil boom of the past, subsidies be the pa-radigm taken by government. However, because of government budget con-straints, and also the absence of the private sectors role, the efforts being failed. Shariah banking have a great obligation to face this huge potential demand. Because of poor farmers was a part of the largest Islamic commu-nity itself and the maqasid Shari'ah philosophy put the protection of man-kind from poverty and indigence as one of the main objectives. Nevertheless, major barriers to technical and economic, made sharia banking still not pre-sent in those efforts. Need a new paradigm which using a comprehensive ap-proach and involve actively participation of all parties to realize those goals. To that end, this paper will try to offer that new paradigm.

Abstract: This study highlights the characteristics of Small and Middle Entrepreneurs (SMEs) as a debtor of micro finance institution (MFI), whether as conventional or sharia type. The study was conducted by taking primary data including 30 debtors of conventional MFI and 29 debtors of Sharia MFI using a questionnaire. In the first stage, the study established several indices to measure the religiosity level using Principal Component Analysis. Additionally, game field experiments use in order to reveal the debtor’s risk preferences. At a later stage, the probit regression model used. This study found that debtors of sharia MFI is relatively more religious. There is also a fact that debtors from both types of MFI have the same risk preferences, risk lover. But debtors in sharia MFI have a relatively lower level one. So, in order to broaden the Sharia MFI inclution, the managers have to pay more attention to at least two other characteristics of SMEs; their age and the years of experience in business management.

Abstract: A study has been made to investigate provisions of water supply in areas where availability of potable water is scarce due to high organic matter, red and yellowish in colour and low in pH. The water quality was determined for surface and shallow ground water. Clean potable water was acquired by dugging a well with concrete casing in podsolic soil, provided with a shallow well hand pump with PVC casing in non-podsolic soil, and one provided with a shallow well hand pump with PVC casing connected to a small water treatment unit in podsolic soil. The study shows that a water treatment unit is urgently needed, to provide a proper water supply sys-tem. The best potable water supply can be provided through the installment of auger shallow well hand pumps with PVC casing and connected to a small water treatment unit. A well with concrete casing alone does not meet the requirement for acquiring potable water.
