Abstract

Abstrak. Pembuatan es krim atau “es puter” yang dilakukan oleh pengusaha kecil selama ini adalah dengan cara memutar tabung secara manual (diputar dengan tangan) selama kurang lebih 1,5 jam. Dengan cara pembuatan seperti ini kurang efisien dan memberatkan pekerja. Tujuan pokok kegiatan ini adalah untuk membuat mesin pemutar es krim yang berisi empat tabung es krim yang mampu bekerja dengan hasil optimal serta mudah cara mengoperasikannya. Hasil kegiatan ini adalah mesin pemutar es krim empat tabung yang dapat berfungsi dengan baik. Produktivitas mesin pemutar adalah empat kali lipat (400%) lebih tinggi dibandingkan dengan alat pemuatar es sebelumnya (manual). Kualitas es krim yang dihasilkan dengan mesin pemutar sama baiknya dengan yang dihasilkan dengan cara manual. Kata kunci: mesin, es krim, produktivitas, efisiensi

Abstract

This article discusses the efforts of  intreprating local Islam manuscripts of Minangkabau, particularly the order of  Syattariyah in Minangkabau. The manuscripts are culturally important since they are related to the daily religious needs of the disciples of the order of Syattariyah in Minangkabau. This is related to the beliefs that to know about the guru, to posses the book, or to listen to the stories about the ulema, the guru  of the order of Syattariyah are essential. The ideolgical perspectives is influenced by the surau teaching system based on the doctrines and books of the teachers. By means of social context analyses of the texts, it is found that one way to reflect the disciples’ respect for the guru(-s) has been done through writing the biography of the respective teachers and understanding their teaching.  Because the guru is considered holy man, his story cannot be written in Latin texts, otherwise it will be considered blasphemy or harâm.Kata Kunci:    surau, Kaum Tua, Kaum Muda, manuscrip, Tarekat Syattariyah, Minangkabau, Islam.

Abstract

Surau is a traditional institution of education in Minangkabau which has important role in developing Islam. In Islamic local discourse, surau became a center of order (tarîkah), the center for excellenceand for defending to criticize the another untrue ideology of Islam. In this context, syaikh from each surau write the manuscript  to critisize the untruth ideology of Islam or social condition. There are four surau located in Padang and Padang Pariaman where many manuscripts can be found. The manuscripts are culturally important since they are related to the daily religious needs of the disciples of the order of Syattariyah in both places. This is related to the beliefs that to know about the guru, to posses the book, or to listen to the stories about the ulema, the guru  of the order of Syattariyah are essential. Besides, the manuscripts are written to criticize opinions of the other Islamic schools whichare not appropriate according to the writer’s Islamic perception.Kata Kunci: tradisi pernaskahan Islam, surau, tarekat Syattariyah, Minangkabau

Vocational education building and development must consider the needs of the industry and the demands of 21st-century skills graduates. For these two requirements, it is necessary to innovate the learning model to improve the students? learning experience and graduates? performance. This study aims to develop a production-based learning model that is integrated with 21st-century learning skills to improve skills in mechanical engineering. The study employed focus group discussion and experts? judgment. This study involved the mechanical engineering lecturers, the head of laboratory at the mechanical engineering department, the head of the department of mechanical engineering, the head of mechanical engineering vocational education, the head of the mechanical laboratory at the vocational schools, mechanical engineering teachers, vocational technology education experts, and curriculum specialists. The results show that the utility, feasibility, propriety, and accuracy of the production-based learning model integrated with 21st-century learning skills met the expected criteria and could be used to improve mechanical engineering skills.

The objective of the research was to study the effect of the used reclaim rubber from scrab rubber roll as a rubber substitution at rubber compounding for shoe sole production. The reclaime rubber was made by mixing between 100 part scrab rubber roll, 30 part reclaiming oil and 2 part reclaiming agent. The mixture was aged to swelling process for 24 hours and devulcanization was conducted at 1500C for 1.5 hours. Properties of the reclaim rubber were identified such as tension at break 46.55 kg/cm2, elongation at break 136.22%, hardness Shore A 52.8, acetone extract 30.4% and polymer contain 36.41%. The rubber compound was made by using special natural rubber of RSS I (Ribbed Smoke Sheet I) mixed with reclaim rubber at ratio of 100/0, 90/10, 80/20, 70/30, 60/40 and 50/50 phr (part hundred rubber) respectively and was also added additives. The mixing was conducted by using mixing mill at 400-600C for 50 minutes. The compound was concluded that the composition between new rubber RSS I and reclaim at the ratio 70/30 has obtained the most favorable physical properties, with respected testing result of tention at break 85.5 kg/cm2, elongation at break 195.3%, hardness 72.2 shore A, tear resistance 42 kg/cm2, permanent set at 50% elongation 0.27%, density 1.39 g/cm3, Grazelli abration resistance 4.05 mm3/kgm and flexing resistance at 150 kcs did not break. However, the physical properties of the compound was able to meet the SNI 12-0778-1989 class C except the abration resistance.  Keyword : reclaim, rubber roll, compound rubber, shoes sole   ABSTRAK Penelitian ini bertujuan untuk mempelajari pengaruh penggunaan karet riklim yang berasal dari skrap roll karet sebagai substitusi karet mentah pada pembuatan kompon karet untuk sol sepatu.

Abstract

Cashew nut shell liquid (CNSL) as a by product of cashew nut industry was not utilized. CNSL can be used to produce a rubber-like materials. The objectives of the research was to study the application of CNSL resin as substitute material for styrene butadiene rubber (SBR) in the carcass compound. CNSL was reacted with formaldehyde resulting a rubbery CNSL-formaldehyde resin. CNSL –formaldehyde resin was prepared by reaction of 100 parts of CNSL, 5 parts of a 37% aqeaus solution of formaldehyde and 2 parts of ammonium hydroxide for 60 minutes at 1500C. Ratio of SBR/CNSL formaldehyde in tyre carcass compunds were 50/0, 40/10, 30/20, 20/30, 10/40 and 50/0, respectively. The results show that substitution CNSL – formaldehyde resin for SBR was up to 10 phr. Increasing amount of CNSL-formaldehyde resins have increase physical properties such as hardness, peel test, and density, but decreased tensile strength,elongation at break, and abrasion resistance. A compound with ratio SBR/CNSL-formaldehyde resin 40/10 performed the best physical properties i.e:139.454 kg/cm2 tensile strength, 710.97% elongation at break, 62 Shore A hardness, 1.124 g/cm3density, 423.477 N/inchi peel test, and 3.214 mm3/kgm abrasion resistance, respectively.   Keywords : cashew nut shell liquid, CNSL-formaldehyde resin, tyre carcass compound.   ABSTRAK Minyak kulit biji jambu mete atau cashew nut shell liquid (CNSL) merupakan hasil samping industri kacang mete yang sampai sekarang belum dimanfaatkan secara optimum. Padahal CNSL dapat dibuat menjadi material yang menyerupai karet. Tujuan penelitian ini untuk mempelajari pengaruh penggunaan resin CNSL sebagai substitusi karet stirena butadiene (SBR) dalam kompon karkas. Resin CNSL terlebih dahulu direaksikan dengan formaldehid menjadi resin CNSL-formaldehid yang menyerupai karet. Resin CNSL-formaldehid dibuat dari resin CNSL 100 bagian, formalin 37% sebanyak 5 bagian, dan NH4OH sebanyak 2 bagian yang direaksikan selama 60 menit pada suhu 1500C. Perbandingan  jumlah karet SBR dengan resin CNSL-formaldehid yang diteliti dalam kompon karkas berturut-turut : 50/0, 40/10, 30/20, 20/30, 10/40 dan 50/0. Hasil penelitian menunjukkan bahwa penambahan resin CNSL-formaldehid dapat mensubstitsi  karet SBR sampai 10 phr. Makin banyak resin CNSL-formaldehid yang ditambahkan menaikkan, sifat kekerasan, daya rekat dan berat jenis namun menurunkan sifat tegangan putus, perpanjangan putus, dan ketahanan kikis. Kompon yang berisi perbandingan karet SBR/resin CNSL-formaldehid 40/10 menunjukkan sifat fisis terbaik yaitu berturut-turut : tegangan putus 139,454 kg/cm2; perpanjangan putus 710,97 %, kekerasan 62 Shore A, berat jenis 1,124 g/cm3, ketahanan kikis 3,214 mm3/kgm, dan daya rekat 423,477 N/inch. Kata kunci : minyak kulit biji jambu mete, resin CNSL-formaldehid, kompon karkas ban.
