Candi Sirih merupakan tinggalan budaya dari masa Hindu-Buddha, yang masih cukup lengkap yang terbuat dari batuan tufa, sehingga dianggap sebagai candi yang tidak umum di Pulau Jawa karena menggunakan batuan yang bukan andesit. Hal inilah yang menjadi pokok permasalahan pada penelitian ini, yang mencakup bahan batuan candi dan kondisi geologi secara umum. Maksud dan tujuan penelitian ini adalah pemetaan geologi untuk mengetahui gambaran keadaan lingkungan alam yang mencakup morfologi, litologi, struktur geologi, dan menentukan lokasi pengambilan sumber bahan batuan untuk pembangunan candi. Metode penelitian diawali dengan kajian pustaka, survei, dan dilanjutkan dengan analisis petrologi, dan interpretasi data. Hasil pengamatan lingkungan memberikan informasi tentang bentang alam yang termasuk pada satuan morfologi dataran, dan satuan morfologi bergelombang lemah. Pola pengeringan permukaan dendritik, radial, dan rektangular, stadia sungai dewasa-tua, dan sungai periodik/permanen. Batuan penyusun adalah aluvial, dan satuan batuan tufa serta struktur geologi berupa sesar normal. Penentuan lokasi bahan batuan tufa (kasar. halus, berlapis) dan serpih untuk pembangungan Candi Sirih berasal dari lingkungan sekitarnya dalam radius 3,5 kilometer bujursangkar.   Sirih Temple is a cultural heritage from the Hindu-Buddhist era, which is still quite complete, made of tufa rock, so it is considered an unusual temple in Java because it uses non-andesite rocks. This is the main problem in this study, which includes the material of the temple rock and geological conditions in general. The purpose and objective of this research is geological mapping to determine the description of the state of the natural environment which includes morphology, lithology, geological structure, and determining the location of the source of rock material for the construction of the temple. The research method begins with a literature review, survey, and is followed by petrological analysis and data interpretation.

Pucang Village was consisted of eruption materials of Merapi Volcano. The relatively high coefficient of permeability of the materials consisting this area caused rainwater to directly infiltrate into the ground. Evaluation of engineering geological conditions was conducted for construction of a detention pond in this area, which had limited water supply for daily activities. The evaluation was conducted on results of a 1:10.000 scale of engineering geological mapping and analyses of 1:10.000 scale of geological disaster maps produced by previous researchers. The engineering geological mapping involved mapping of morphological condition and active geomorphic process, lithological condition, existence of geological structure, and water source location. The evaluation results showed that the proposed location met the land suitability criteria for detention pond construction based on the morphological condition and active geomorphic process, existence of geological structure, and water source location, but did not meet those based on the lithological and vulnerability to Merapi Volcano eruption disaster. Construction of impermeable layer to prevent water seepage into the ground and periodic removal of sediment in the base of the detention pond were suggested to be carried out to keep the detention pond functioning properly.

Development of settlement area in Sidosari area and the surroundings requires complete understanding of the engineering geological conditions, including susceptibility to landslides, to prevent damaged properties and loss of lives. Surface engineering geological mapping at a 1:25000 scale was conducted to develop a detailed landslide susceptibility map for spatial planning and to identify most controlling factor of landslides in the research area based on conditions of geomorphology, rock and soil, geological structure, groundwater seepage, and land use. The engineering geological mapping showed that landslides commonly occurred in the moderate slopes of the denudational hill landform having slope inclination ranging from 9 to 17°, in the areas covered by residual soils of the vitric tuff 2 unit, in the areas of no groundwater seepage, and in the settlement areas, including in Kranjang Lor area where soil creeping occurred. The high susceptibility zone covered 55.5 % of the research area and was characterized by having slope inclinations ranging from 9 to 35°, engineering geological units of vitric tuff 2 and tuff breccia, and land uses of rice and dry fields and settlement. The low cohesion and very high swelling potential of the residual soils of the vitric tuff 2 unit were considered to be the main controlling factor of landslides in the research area.

In the discipline of Islamic law research, strong proofing and clear Istinbat method are key pillars in the construction of Islamic law based on the application of the science of usul al-fiqh and maqasid al-shari'ah. However, what happens at the state of Johor’s fatwa institution is the opposite. The fatwa research methods applied by the Fatwa Committee of Johor in resolving current fatwa issues is not based on the right and true discipline of Islamic law research. In fact, current inputs related to fatwa issues are not explicitly stated in the method of determining the law either in the form of reality or scientifically verified. Therefore, this paper will discuss the fatwa procedures undertaken by the Fatwa Committee of Johor based on the methods applied in resolving current issues. The research methodology adopted is library and interview methods. This study shows that fatwa management and production in the state of Johor is placed under the jurisdiction of the Mufti of Johor’s Department. The methods adopted by the Fatwa Committee of Johor covers two methods, namely: internal research methods including literature review through the application of original source and proofs based on syarak. Second: field research method that includes an external review or going to the location of study such as conducting observation, questionnaires and interviews including referrals to specialists of different fields. Maslahah and mafsdah consideration are also implemented by the Fatwa Committee in every fatwa decision based on the standard that meets the interests of maqasid al-shari'ah. Keywords: Metode, fatwa, istinbat, usul al-fiqh, maqasid al-shari’ah ABSTRAK Dalam disiplin penyelidikan hukum Islam, kekuatan pendalilan dan kaedah istinbat yang jelas merupakan tunggak utama dalam pembinaan hukum Islam berasaskan kepada aplikasi ilmu usul al-fiqh dan maqasid al-shari’ah. Namun begitu, apa yang berlaku di institusi fatwa negeri Johor adalah sebaliknya. Kaedah penyelidikan fatwa yang diaplikasi oleh Jawatankuasa Fatwa Negeri Johor dalam menyelesaikan isu fatwa semasa tidak berasaskan kepada disiplin penyelidikan hukum Islam yang tepat dan sebenar. Malahan input-input semasa yang berkaitan dengan isu fatwa juga tidak dinyatakan secara jelas dalam kaedah penentuan hukum sama ada dalam bentuk realiti yang berlaku atau pembuktian secara saintifik. Justeru, kertas kerja ini akan membincangkan prosedur fatwa Jawatankuasa Fatwa Negeri Johor berdasarkan metode-metode yang diaplikasi dalam menyelesaikan isu-isu yang bersifat semasa. Metodologi kajian yang digunakan dalam kajian ini adalah melalui metode perpustakaan dan metode lapangan. Hasil kajian menunjukkan bahawa pengurusan dan pengeluaran fatwa di negeri Johor hanya terletak di bawah bidang kuasa Jabatan Mufti Johor. Metode fatwa yang diamalkan oleh Jawatankuasa Fatwa Negeri Johor merangkumi dua metode iaitu pertama, kaedah penyelidikan dalaman yang merangkumi kajian kepustakaan menerusi pengaplikasian dari sumber asas dan dalil-dalil syarak. Kedua, kaedah penyelidikan lapangan yang meliputi kajian luaran atau turun ke lokasi kajian seperti observasi, soal selidik dan temubual dan rujukan kepada pakar dalam bidang yang berlainan. Pertimbangan maslahah dan mafsdah juga dimplementasikan oleh Jawatankuasa Fatwa dalam setiap keputusan fatwanya berasaskan standard yang menepati kepentingan maqasid al-shari’ah. Kata kunci: Metode, fatwa, istinbat, usul al-fiqh, maqasid al-shari’ah

Abstract The study was set to examine the differences between religion and religiosity and to explore how communities can be protected against religious violence. The study also intended to investigate the motives and the effect that religious violence has had throughout history. The study employed the qualitative research method whereby the researcher carried out a meta-analysis synthesis of different research findings to make conclusions and implications that could answer the study questions. Using the literature review they conducted, the researchers carried out data collection. As such, the researcher employed the bottom-up approach to identify the problem and the questions along with the investigation framework of what they decided to explore. The findings of the study revealed that religious backgrounds should be the cornerstone to realize the diff erence between religion and religiosity. Religion is of divine origin whereas religiosity is specifically a humanistic approach and a behavioral model. The religious violence phenomenon is formed by interlocking factors such as the interpretation of religious texts which clearly adopt thoughts and heritage full of violence camouflaged by religion. It is recommended that governments use a strong strategy employing the educational system, summits and dialogs to successfully overcome religious violence. The summits on religion should result in starting a dialog that ensures acceptance of the different religions.
