Abstract

Penelitian ini bertujuan untuk mengetahui produktivitas alat destilasi tenaga surya jenis kolektor plat datar dalam menghasilkan air bersih dan garam. Indonesia yang terletak ditengah kepungan air laut, kekurangan air bersih dan garam banyak menimpa masyarakat yang tinggal di pesisir pantai. Oleh karena itu diperlukan teknologi untuk mengolah air laut menjadi air bersih dan garam. Energi surya yang tersedia sepanjang hari di Indonesia dapat dimanfaatkan sebagai sumber energi yang gratis untuk destilasi air laut. Destilasi surya merupakan salah satu cara untuk mengolah air laut dalam menghasilkan air bersih dan garam dengan cara pemanasan dan penguapan pada kolektor surya. Prinsip kerja alat yaitu radiasi surya masuk ke dalam kolektor melalui kaca penutup transparan menuju plat penyerap, pada plat penyerap radiasi surya dirubah menjadi panas. Air laut pada basin akan menjadi panas, air menguap dan menempel pada kaca penutup bagian dalam. Akibat adanya perbedaan temperatur antara di dalam basin dengan lingkungan terjadi kondensasi yang menempel pada kaca penutup akan mengalir ke bawah mengikuti kemiringan kaca penutup. Pengujian dilakukan secara terus menerus dari pagi hingga sore setiap hari sampai air laut dalam basin menguap atau menjadi kering. Hasil pengujian menunjukkan dengan luas kolektor 1,6 m2, volume air laut dalam basin 10.000 ml dan intesitas surya rata-rata 542 W/ 2m diperoleh air bersih rata-rata 1360 ml/hari serta garam sebanyak 642 gram pada hari ketujuh.

Abstract

Metode perencanaan telah dikembangkan untuk meningkatkan performa dari alat heat exchenger tipe shell and tube. Beberapa penelitian didesain hanya untuk tujuan khusus untuk memperoleh unjuk kerja yang baik dari heat exchenger itu sendiri. Tujuan dalam penelitian ini adalah mencari nilai laju perpindaha kalor, nilai koefesien perpindahan panas menyeluruh. Performa dari alat penukar panas akan dianalisa untuk temperatur masuk fluida panas tidak lebih dari 60 oC dengan kapasitas 70 liter, sedangkan untuk temperatur fluida dingin dilakukan pengujian dengan memvariasikan bukaan katup dengan variasi bukaan katup 1/4, 2/4, 3/4, 4/4. Setelah dilakukan pengujian dan analisa data di dapatkan nilai dimana untuk laju perpindahan kalor pada alat uji heat exchenger mengalami kenaikan nilai di setiap bukaan katup yang dilakukan di dapatkan nilai sebesar 20,937 watt untuk bukaan katup 1/4 sedangakan untuk bukaan katup 4/4 mendapatkan niai sebesar 23.395,55 watt, sedangkan untuk nilai laju perpindahan kalor menyeluruh juga mengalami kenaikan nilai pada setiap variasi bukaan katup yang di lakukan pada fluida dingin untuk bukaan katup 1/4, di dapatkan nilai 1549,615 W/m2.oC sedangkan untuk bukaan katup 4/4 di dapatkan nilai 14180,96 W/m2.oC. Dapat disimpulkan bahwa semakin besar bukaan katup yang dilakukan maka nilai laju perpindahan kalor akan meningkat sama seperti koefesien perpindahan panas menyeluruh.. Kata Kunci: perpindahan, kalor, katup, koefisien

Abstract

ABSTRACT Training on making paving blocks from plastic waste (colored and or clear bags) for cleaning services of campus 3 Universitas Bung has been conducted. The Community Service (PKM) aims to transfer knowledge and skills in the manufacture of paving blocks which have a higher selling value than plastic bag waste. The long-term goal of this program is to support the Padang City Government program to reduce the amount of waste to the Final Disposal Site and become a community business opportunity to increase sources of income. The methods used in this PKM are: 1) preparation of socialization activities, and 2) counseling and training. The campus cleaning service is enthusiastic about this activity and considers that the training adds to their insight in the utilization of plastic waste into paving blocks, which they never knew about that.

Abstract

Bulletproof material is used as a bulletproof vest material that functions to protect the human body from the threat of physical attack, especially attacks from firearms. Bulletproof material serves to reduce the kinetic energy of the projectile so it does not hit the bulletproof vest user. The main material in the manufacture of bulletproof material is steel with a high density so that the weight of the bulletproof material is high which causes the user to be unable to move freely. Composite is a material consisting of two or more elements that have good mechanical properties and low density so that it can be used as an alternative to steel for bulletproof materials. The bulletproof material used was reinforced with bamboo fiber with a matrix of epoxy resin/hardener mixture and the addition of 20, 25, and 30 ml ceramic granules, the composite material was tested for ballistics using a variation of the firing range parameter 2; 2.5; and 3 m. Based on the results of ballistic tests, all variations of the addition of ceramic granules were able to reduce the energy of the projectile with a penetration depth of < 1 mm where the kinetic energy of the projectile was 209.83 joule. Based on the macro photo analysis of projectile traces on the bulletproof material, the cracks that occur in the bulletproof material are ductile cracks due to the spread of the cracks to other areas on the surface of the bulletproof material.

Abstract

Kafa'ah is one of the important things in marriage, this is intended to produce harmony in the household so that it can be nurtured and the creation of a happy and harmonious household. Islam provides guidelines for choosing a partner based on four important criteria, namely religion, wealth, descent, and beauty. The different views were expressed by community leaders in Gampong Lada Village, namely expanding the meaning of kafa'ah in marriage by adding educational, position and job criteria in interpreting the meaning of kafa'ah. The problem in this thesis is how the meaning and criteria of kafa'ah in marriage and how the community leaders of Gampong Lada interpret kafa'ah and its criteria in marriage. The type of research used by the author in compiling this thesis is descriptive qualitative research. The results of this study indicate that the community leaders of Gampong Lada Village are very understanding about the meaning of kafa'ah in marriage, because the community leaders of Gampong Lada are very knowledgeable about religious knowledge. Gampong Lada community leaders interpret kafa'ah as equality, equivalence, and harmony between the prospective groom and the prospective bride when they want to get married. And the community leaders of Gampong Lada are of the view that for now the aspects of property, education, work, and position are very relevant in terms of kafa'ah, but even so, community leaders in Gampong Lada Village, Mutiara Timur District, and Pidie Regency do not rule out the religious aspect of the kafa issue. At this point, the community leaders of Gampong Pepper view that the religious aspect as the most important aspect of the meaning of kafa'ah in marriage.

Abstract

Coconut shells are a prevalent agricultural waste product in Indonesia. Currently, there is a trend toward developing heterogeneous catalysts for the esterification reaction of vegetable oils to produce biodiesel. These catalysts are made from biomass carbon. This research aims to investigate the effectiveness of using carbon precursors derived from coconut shells to create a heterogeneous acid catalyst for the esterification of waste cooking oil (WCO). Another objective is to identify the optimal esterification reaction conditions catalyzed by the developed sulfonated carbon catalyst, which exhibits the highest performance in converting free fatty acids (FFA). The coconut shells were carbonized using conventional methods and functionalized with concentrated sulfuric acid through dry impregnation. This process was conducted under various sulfonation conditions. The varied preparation parameters included the carbon-acid ratio (1:7.1, 1:10, 1:12.8, and 1:15.7% w/v), contact time (1 to 4 days), and calcination temperature (270C, 340C, and 450C). The charcoal and catalyst developed in this research were characterized through composition analysis using X-ray fluorescence (XRF) and crystal phase analysis using X-ray diffraction (XRD). The best catalyst preparation conditions were determined to be a carbon-acid ratio of 1:15.7% (w/v), a contact time of 3 days, and a calcination temperature of 340C. The optimal esterification reaction conditions were achieved using a mole ratio of methanol to WCO of 12:1, with a catalyst amount of 1.6%, for a duration of 1 hour at a temperature of 60C. This reaction resulted in a conversion rate of 84.6%.
