Background:
Thin films of PbS were prepared onto glass substrates by using a
simple and cost-effective CBD method.

Methods:
The influence of deposition time on structural, morphology and optical properties
have been investigated systematically. The XRD analysis revealed that PbS films are polycrystalline
with preferred orientation in (200) direction. Enhancement in crystallinity and
PbS crystallite size has been observed with an increase in deposition time. The formation of
single-phase PbS thin films has been further confirmed by Raman spectroscopy. The surface
morphology analysis revealed the formation of prismatic and pebble-like PbS particles and
with an increase in deposition time, these PbS particles are separated from each other without
secondary growth. The data obtained from the EDX spectra show the formation of high-quality
but slightly sulfur-rich PbS thin films over the entire range of deposition time studied.

Results and Conclusion:
All films show an increase in absorption with an increase in deposition
time and strong absorption in the visible and sub-bandgap regime of the NIR range of
the spectrum with red-shift in band edge. The optical band gap shows a decreasing trend, as
deposition time increases but it is higher than the bandgap of bulk PbS.

Objective:
Herein, we report the effect of variation of hydrogen flow rate on the
properties of Si:H films synthesized using PE-CVD method. Raman spectroscopy analysis
show an increase in crystalline volume fraction and crystallite size implying that hydrogen
flow in PE-CVD promotes the growth of crystallinity in nc-Si:H films with an expense of a
reduction in deposition rate.

Methods:
FTIR spectroscopy analysis indicates that hydrogen content in the film increases
with an increase in hydrogen flow rate and hydrogen is predominantly incorporated in Si-H2
and (Si-H2)n bonding configuration. The optical band gap determined using E04 method and
Tauc method (ETauc) show an increasing trend with an increase in hydrogen flow rate and E04
is found higher than ETauc over the entire range of hydrogen flow rate studied.

Results and Conclusion:
We found that the defect density and Urbach energy increases with
an increase in hydrogen flow rate. Photosensitivity (σPhoto /σDark) decreases from ~103 to ~1
when hydrogen flow rate is increased from 30 sccm to 100 sccm and can be attributed to
amorphous-to-nanocrystallization transition in Si:H films. The results obtained from the present
study demonstrated that hydrogen flow rate is an important deposition parameter in PECVD
to synthesize nc-Si:H films.

Published: May 2020

Objective: Simple, sensitive, precise, reproducible, and validated visible spectrophotometric methods have been developed for the determination of leukotriene receptor antagonist drug, namely, montelukast (MNT) sodium in bulk and pharmaceutical preparations.
Methods: Three spectrophotometric methods are based on the formation of yellow-colored ion-pair complexes between MNT sodium and three dyes, bromocresol green, bromophenol blue, and methyl orange with absorption maxima at 420, 416, and 426 nm, respectively.
Results: The stoichiometric ratio of the formed ion-pair complexes was found to be 1:1 (drug:reagent) for all methods, as deduced by Job’s method of continuous variation. Several parameters such as pH, buffer type and volume, reagent volume, sequence of addition, and effect of extracting solvent were optimized to achieve high sensitivity, stability, low blank reading, and reproducible results. Under the optimum conditions, linear relationships with good correlation coefficients (0.9993–0.9999) were found over the concentration ranges of 1.0–10, 1.0–12, and 1.0–16 μg/mL with a limit of detection of 0.30, 0.29, and 0.27 μg/mL for bromocresol green, bromophenol blue, and methyl orange methods, respectively.
Conclusion: The proposed methods were validated in accordance with ICH guidelines and successfully applied to the analysis of MNT sodium in pharmaceutical formulations. Statistical comparison of the results obtained by applying the proposed methods with those of the reference method revealed good agreement and proved that there was no significant difference in the accuracy and precision between the results.

Objektifikasi QiṢās Dan Diyat: Sebuah Tawaran Pembaharuan KUHP
Authors: Sulaiman Akhmad , Ikhlas Nur 
Published: May 2020

The reporting media indicates that the killing ceses in Indonesia keep on rise. It means that applying killing criminal law that refers to KUHP is not effective. This condition requires KUHP reforming because the right of human life must be vouched by the government. The criminal law of Indonesia must punish a killer more forceful. The writers offer qiṣās and diyat to be applied in Indonesia but they have to pass through objectification. According to Kuntowijoyo, objectification is interpreting religion’s internal doctrines into objective categories in order to be able to be applied, actualized, and accepted by moslem and nonmoslem. It is research and development that strives for developing Kuntowijoyo’s objectification on KUHP reforming. With changing qiṣās term into die punishment, diyat into compensation for victim’s family, and adjusting with objective condition in Indonesia, qiṣās and diyat will be accepted by every national of Indonesia and become solution of criminal law of Indonesia that is not effective.

The Concept Of Adultery Post-Revision Of The Penal Code
Authors: Junaidi M. , Imansyah Resky Gustiandi Candra 
Published: May 2020

Zina is an act that is prohibited by religion as well as by the state. Adultery is arranged in two rules; in Indonesia it is regulated in the Criminal Code called KUHP. For the case of adultery, it uses offense complaint, which means that it will only be processed criminal law if there is one spouse who reported this legal event. While in Islam, zina’s actions are regulated in the Qur’an and Hadith. The problems appeared when the article that regulates zina in the existing criminal code law will be revised its offense from the offense complaint becomes a general offense. This research is under normative research. The type of data in this study is secondary data which were collected by the study method library. The data collected were analyzed by qualitative descriptive method. The result shows that in the Islamic context of adultery, the reporting and proofing process requires only 4 witnesses and it must be seen by firsthand. Whereas in the draft amendment of the criminal law, the adultery will be regulated by general offense resulting in the proof that should be studied not only from the sociological aspect but also the theological aspect.
Criminal Sanctions As an Eradication Strategy Of Corruption: A Critical Study from the Perspective of Islamic Criminal Law
Authors: Darudin Mohammad 
Published: May 2020

The spirit of anti-corruption movement has been a motion since reformation era in 1998 and the government has issued various policies. Firstly, the policy relating to the substance of the law, the government has passed various laws and ratified international conventions. Secondly, the regulations concerning law enforcement agencies, the government has established the Corruption Eradication Commission, Corruption Crime Court, the Center for Reporting and Analyzing Financial Transactions (PPATK), the Witness and Victim Protection Agency (LPSK), and the establishment of internal supervisory bodies. However, these efforts seemingly face failure. The facts show that corruption increases in the executive, legislative and judicial institutions, from the center to the region level. The failure of corruption eradication can be one of the reasons that indicates the formulation of criminal sanctions in Law No. 20/2001 for corruption is weak, not appropriate for the negative impacts of the crime. Consequently, the punishment imposed has no deterrent effect for either the perpetrators or others. It is contrast to the concept of sanctions in Islamic criminal law, sanctions imposed on the perpetrators must be comparable with their evil deeds (Qur'an Surah 42, verse 40), with the aim to benefit for human both individual and collective. According to the concept, this article will examine criminal sanctions based on Islamic criminal law as an eradication strategy of corruption. The results of this article can be a consideration for the revision of the framework in formulating criminal sanctions contained in Law No. 20 / 20011 concerning corruption.

Published: May 2020

This research was a comparative study on the effect of young age in the crime of murder between Islamic jurisprudence and Indonesian law. The presence of children around us needs attention, especially with regard to their behavior, which is out of control. the phenomenon of their deviation is one of the negative social phenomenon which required protection, guidance and education. According to previous studies, children who deviated and were not controlled would become a criminal when he reaches adulthood. Nowadays, the children's delinquency is widely spread, they are involved in committing crimes such as drugs, theft, fighting, and increased to murder. This research will focus on the murder committed by under age children, because murder is a very dangerous crime to the indivdual life and is one of the law violation againts the five principles of shariah (daruriyat al khamsah).

Authors: Hasanah Uswatun 
Published: May 2020

Technology development cause crime in the world that keep fluctuating and changing. Cyber crime is one of crime activities which takes place in the internet and develop fast globally, even faster than the conventional crime. Cyber crime is not only about computer-crime, cyber-terrrorist, cyber-narco-terrorist, but also capable to make impact toward state economy. This paper aims to understand the implementation of Islamic law or Islamic criminal law to see cyber crime. Islamic criminal law has been developed many years ago before arrival of information technology. This paper describes how Arab, Brunei Darussalam, and China reduce crime by adoption of islamic law. Islamic law what meant here is a law based on Islam, not a law made by Muslims then applied by Muslims. Islamic law can be practiced in every single country, although they don’t declare explicitly or they think that what have they done is not islamic law. Islamic law contains general principles to respon and develop efficient ways to overcome cyber-crime.
Menakar Progresivitas Hukum Wakaf dalam Pengembangan Wakaf Uang di Indonesia
Authors: Efendi Mansur 
Published: May 2020

This study explained the progressivity of waqf law in Indonesia, especially cash waqf development. The progressivity of waqf law is good enough to respond to global challenges or field needs. The progressivity of waqf law in Indonesia can be observed from the development of waqf’s act regulations from pre-independence era until the post-reformation era. In cash waqf, there is fundamental law progressivity. It marked by act No. 44 year 2004 about waqf. Those act described new paradigm must be built on waqf management in Indonesia. Furthermore, those act also gave a space for cash waqf as a part of waqf development in Indonesia. Another progressivity which appeared in those act is waqf treasure object. Act No. 44 year 2004 confirmed that waqf treasure object is not only immovable object, as public understanding, but also applied on the movable object. Furthermore, the progressivity of waqf law has reached on waqf management and its institutional aspect. At least, this progressivity described collective awareness on the strategic role of waqf in Indonesia’s economics.
