    The calorific value is a parameter of palm biomass to determine its energy value. Extractives of wood is one of the factors that affect the calorific value. This study aimed to prove the positive effect of extractives on increasing calorific value by identifying the effect of adding extractives on low calorific value biomass. The study used three species wood energy, i.e., Calliandra calothyrsus, Gliricidia sepium, and Leucaena leucocephala. The soxhlet extraction was carried out to isolate extractives from sample. The calorific value sample and residue after extraction were analyzed to evaluate the changes of calorific value due to loss of extractives. The effect of extractives on the calorific value was confirmed by adding wood extractives to the palm biomass. The results showed that the extraction process reduced calorific value of residue ranging from 2.63 to 5.88%, and the bark it ranged from 5.52 to 6.70%. The addition of wood extractives to palm biomass increased the calorific value about 5.86-10.33%, while the addition of extractives from bark increase the calorific value by 6.45-9.05%. Based on the results of these studies prove that extractives have a positive effect on increasing the calorific value and can be used as an additive to increase the calorific value of biomass

    Characterization of Surface Active Shell Charcoal Nyamplung Seeds (Calophyllum inophyllum Linn). Chemical and physical activation of nyamplung shell with 0%, 5%, and 10% H3PO4 for 60 and 120 minutes has been carried out to prepare activated charcoal. The purpose of this experiment was to look into the characteristic of nyamplung shell activated charcoal surface. Nyamplung shell was carbonized into charcoal, then activated by immersion in H3PO4 solution using 0%, 5% and 10%, for 24 hours, and heated in retort at two temperatures (700 and 800 oC) and two duration (60 and 120 minutes). The material were characterized by fourier transform infra red (FTIR), scaning electron microscope (SEM) and X-ray diffraction (XRD). The FTIR spectrum show that activated charcoal has OH, C-H, C-O and C=C bonds. The bonds of OH and C-O indicated that the treatment was produced polar activated charcoal. The porous texture was influenced by H3PO4 concentration. The porous with dimension \u3c5 \u3eμ being predominant at low concentration of H3PO4 (0% and 5%) but larger amount of H3PO4 (10%) produced wide pore with dimension \u3e5 μ

Her fetus. The research method used in this work is a qualitative method, which belongs to the type of library research (library research).

An example in this case is how Islam strictly forbids adultery among its people, this is for the protection of Maqasid Sharia, one of which is to protect future generations. Also, the period of \u27iddah for a pregnant woman divorced from Qobla Dukhul is determined according to the Hanafi and Syafi\u27i schools, so in this case the two schools of thought differ in the meaning of Qobla Dukhul, which may have legal implications.

Adapun alasan penulis hanya mencukupkan perspektif mazhab Hanafi dan Syafi’i adalah karena hanya kedua mazhab inilah yang memandang bahwa wanita yang hamil karena sebab zina maka ia boleh dinikahi tanpa harus menunggu lahirnya janin yang ia kandung. Metode penelitian yang digunakan dalam skripsi ini adalah metode Kualitatif, dengan jenis penelitian kepustakaan (Library Research). Analisa penelitian menunjukkan bahwa Islam adalah agama yang sempurna, sehingga segala hal yang merupakan hal baik bagi seoang hamba menurut Allah telah diatur dengan sedemikian rupa. Sebagai contoh dalam hal ini adalah bagaimana Islam itu melarang keras ummatnya melakukan zina, hal ini untuk menjaga maqashid syari’ah yang mana salah satunya adalah untuk menjaga keturunan. Begitu pula tentang penentuan masa ‘iddah wanita hamil yang diceraikan qobla dukhul menurut mazhab Hanafi dan Syafi’i, maka dalam hal ini kedua mazhab tersebut berbeda pandangan dalam maksud dari qobla dukhul yang dapat berimplikasi hukum, sehingga dalam penentuannya ada sedikit perbedaan pandangan antara kedua mazhab tersebut.Kata kunci: Masa ‘Iddah; Qobla Dukhul; Hanafi; Syafi’
