Abstract

Potensi pasir besi di Pantai Selatan Kabupaten Lumajang cukup besar tapi belum dikelola secara mendalam dan modern. Penelitian ini bertujuan untuk mengetahui kandungan mineral magnetik pasir besi yang ada di Pantai Selatan Kabupaten Lumajang agar dapat memberikan informasi dan bahan kajian dalam pengembangan pengolaan pasir besi ke depan. Metode yang digunakan adalah metode separasi magnetik menggunakan magnetik separator untuk memisahkan dan mendapatkan konsentrat pasir besi titanomagnetite yang merupakan senyawa mineral besi yang kaya kandungan titanium. Berdasarkan hasil analisa XRD diketahui bahwa kandungan minerak pasir besi Pantai Selatan Kabupaten Lumajang hasil separasi magnetik mengandung mineral magnetik 39,4% dan non magnetik 60,6% yang terdiri dari senyawa kelompok mineral besi magnetite, titanomagnetite, iron titanium oxide, augite serta pengotor berupa senyawa silika yakni bustamite, albite, dan anthophyllite. Untuk hasil analisa XRF menunjukkan kadar titanium dan besi meningkat setelah dilakukan separasi magnetik pada pasir besi Pantai Selatan Kabupaten Lumajang. Kadar titanium meningkat sebesar 3,42 % dan besi 49,6 %.

Abstract

Nowadays consumers tend to substitute their habits in consuming cow milk into soy milk since it has reliability on health issue, taste, and healthy lifestyle. Referencing to prior researches, health consciousness and main theory of planned behavior (TPB) factors including attitude, subjective norms, and perceived behavioral control significantly influence consumer purchase intention. Researchers aimed to analyze health consciousness influence toward consumer purchase intention to cow milk and soy milk and formulate managerial implications to escalate consumer purchase intention to cow milk and soy milk. This research was conducted in Jakarta, Bogor, Depok, Tangerang, and Bekasi (Jabodetabek) area from October 2023 until April 2024 with 300 respondents. Researchers used voluntary response sampling as sampling method. Analysis methods used by researchers were descriptive analysis, structural equation modelling-partial least square (SEM-PLS) analysis, and importance performance matrix (IPMA) analysis. Results showed that health consciousness doesn’t influence purchase intention to cow milk significantly yet influences purchase intention to soy milk significantly. Otherwise trust, attitude, subjective norms, and perceived behavioral control influence purchase intention to both milks significantly. Furthermore, consumer purchase intention toward cow milk and soy milk can be escalated through improving performances of trust and subjective norms. For trust, producer needs to promote producer reputation, keep up the production standards, and design informative and attractive packaging. For subjective norms, producer needs to conceptualize informative and attractive advertising, conducting sales promotion, public relation, personal selling, and direct marketing.

Abstract

Peningkatan aktivitas mengajar secara daring terlebih saat masa darurat penyebaran virus COVID – 19 melanda, membuat tenaga pendidik utamanya seorang guru sangat terbantu apabila memiliki kecakapan dalam penggunaan teknologi, untuk menjangkau para murid yang melaksanakan pembelajaran dari rumah. Oleh karena itu, perlu diadakannya peningkatan komptenesi guru dalam bidang digital education sesuai dengan era saat ini. Berdasarkan kendala yang dimiliki mitra yaitu kurangnya keterampilan SDM (guru) dalam mengolah media pembelajaran berbasis digital untuk meningkatkan minat belajar siswa, agar siswa dapat memahami pembelajaran meskipun menggunakan sistem belajar online utamanya di SMA Negeri 1 Bahodopi. Sesuai pelaksanaannya, Kegiatan peningkatan kompetensi guru di SMA Negeri 1 Bahadopi telah terlaksana dengan baik, namun ada beberapa kendala yang diharapi selama kegiatan ini berlangsung yaitu ketidaksesuaian waktu pelaksanaan, materi yang diberikan belum terperinci, serta keterbatasan perangkat pendukung pembuatan video. Sehingga, para peserta yang terdiri dari guru sekolah dan tim pelaksana menggunakan berbagai peralatan yang ada. Demi mendukung kegiatan tersebut berlangsung dengan baik.

Abstract

Dalam setiap siklus pemesinan, khususnya pada sistem pembubutan, tingkat kehalusan merupakan salah satu penanda untuk mencapai akurasi benda kerja. Dalam kondisi itu, sifat pahat sangat esensial dalam menciptakan benda kerja dengan tingkat kekasaran yang masuk kategori akurasi presisi. Maka dari itu kekerasan mata pahat sangat berpengaruh, sehingga penulis berupaya membuat mata pahat bubut karbida menjadi lebih keras dari standarnya dengan metode pack carburizing. Mata pahat karbida merupakan mata pahat potong yang memiliki nilai kekerasan HRc = 90–93. Pada penelitian ini juga bertujuan menghasilkan pahat bubut dengan memanfaatkan kikir bekas praktikum kerja bangku dengan metode pack carburizing. Sehingga dapat dibandingkan nilai kekerasan dan pengamatan mikro hasil pack carburizing dari pahat karbida dan mata pahat dari kikir bekas sebelum dikarburasi dengan yang sudah dikarburasi. Sehingga didapatkan hasil nilai kekerasan mata pahat karbida sebelum karburasi adalah 1615,37 HV dan setelah karburasi 1746,94 HV. Sedangkan mata pahat dari kikir bekas sebelum karburasi adalah 564,7 HV dan setelah karburasi didapatkan nilai kekerasan vickers adalah 666,18 HV.

Abstract

The purpose of this study is to determine the effect of power on marking quality, namely groove geometry and marking visibility and corrosion rate on AISI 304 stainless steel fiber laser marking material in corrosive seawater media. This is important because based on the results of the analysis report from the information department, the results of fork and spoon products experience corrosion, especially in the area of laser marking results. In this study, the surface of AISI 304 stainless steel material is given laser marking treatment with power variations, namely 20 and 60 W. The results of SEM testing will be carried out to obtain data on the results of groove geometry and visibility of the marking results. Furthermore, the AISI 304 stainless steel material from the marking is immersed in corrosive sea water media for a span of 60, 90 and 120 days to measure the corrosion rate that occurs. As a result, the AISI 304 stainless steel marking material is also subjected to SEM observation to determine the type of corrosion and surface morphology of the laser marking results due to the influence of corrosion that occurs. It is expected that the results of this study will be able to provide recommendations for work process parameters in laser marking that can be applied to spoon and fork products as optimal parameters for improving the quality of better marking results.

Abstract

Much research in the manufacturing industry has been conducted on variations in cutting force, temperature, and chip directly related to tool wear and cutting performance. Therefore, this research analyzed the cutting performance of cutting tools from the pack carburizing-used files against the results of turning facings. Then, the chisels were welded to ISO 6 tool holders after welding. The chisels were used to turn low carbon steel ST-37 with a diameter of 50.4 mm using a timeway CL-460 lathe with 0.2mm feeding and 400, 605, 910, and 1330 RPM variations. The test results indicated that the bit of carbide from the pack carburizing had a roughness value of 0.890 µm, belonging to class N6. Hence, the roughness value was lower (smoother) than turning facing using a file used from pack carburizing with a roughness value of 3.014 µm.
