Abstract

Milling is widely applied to process train components, especially for finishing wheel-set, boogie frames, and slotting shafts. The cutting forces of milling during operation is important to analyze because they affect on the final product. The analysis can be experimental data observation or simulation. This article presents simulation of cutting forces in up-milling with various input parameters using Octave open software. The simulation results showed that the exit angle (?e) was 80o and 60o for simulation 1 and simulation 2, respectively. The start angle (?s) was 0o for both simulation because it was up-milling process. Since the effective cutting angles were less than the interval angle of cutting edges (90o), only single cutting edge was involved in cutting. In addition, the cutting force was influenced by the cutting parameters, so that there were cutting force fluctuations during machining process. Differences in radial depth of cut, feed per tooth, and effective cutting angle affected in the differences of the cutting force quantity. In simulation 1, the resultant cutting force reached 400 N, while the cutting force Fx and Fy are 250 N and 325 N, respectively. In simulation 2, the resultant was 700 N, and 500 N and 420 N for Fx and Fy cutting forces, respectively. Spindle rotation speed did not affect on the quantity of cutting force but affects on the cutting time. In simulation 1 with a spindle speed of 7500 rpm, it took a cutting time of 0.008 seconds. While in simulation 2, the cutting time was slower, namely 0.012 seconds. This was because the spindle rotation speed reduced to 5000 rpm. The simulation also proved the characteristic frequency of milling process; tooth passing, and several harmonic frequencies.

Abstract

ABSTRAK Legalisasi perkawinan via penetapan hakim suatu pengadilan agama merupakan itsbat nikah. Itsbat nikah dilaksanakan pada berjenis-jenis alasan dan motif misalnya dikarenakan pernikahan yang dilaksanakan sebelumnya dilaksanakan secaran hukum Islam sahaja dan belum dicatat pada Kantor Urusan Agama (KUA) yang lazim disebut dengan nikah di bawah tangan atau nikah siri. Pemandangan perkawinan nikah siri terdapat banyak sekali ditemui pada berbagai wilayah di Indonesia khususnya di daerah Kota Tanjungbalai. Kata kunci: Pelaksanaan, Isbat, Nikah, Kota, Tanjungbalai. ABSTRACT The legalization of marriage through the ruling of a religious court judge is the basis of marriage. Marriage rituals are carried out for various reasons and motives, for example because the previous marriage was carried out under Islamic law only and has not been recorded at the Office of Religious Affairs (KUA) which is commonly referred to as an underhand marriage or unregistered marriage. There are many views of unmarried marriages found in various regions in Indonesia, especially in the Tanjungbalai City area.

Abstract

In the changing atmosphere of society today, families with Islamic cultural backgrounds often clash with the new values brought about by the new social system. The problem in educating teenagers is inevitable. In this case the need for certain knowledge in building effective family communication patterns so as to be able to deliver teenagers who have good emotional development. In this case parents are confronted between cultural values that are still maintained with new cultural values. His opinion quoted Friendly which explained that family communication is the readiness to speak openly to every thing in the family both pleasant andunpleasant, and also ready to solve problems in the family with conversations that are lived with patience and honesty and openness. From this, it can be understood that family communication can be established to provide something that can be given to every other family member, so that with this communication problems that occur between family members can be discussed by taking the best solution.

Abstract

Hyperpigmentation is a disorder of the gingiva caused by various factors including heredity, disease, drugs, smoking habits. This can occur because of the accumulation of melanin pigment in the basal gingival layer resulting in a brownish or blackish color on the surface of the gingiva which when viewed aesthetically is not good because it is not like the normal gingival color of coral pink. Objective: to get the gingival color back to normal, namely coral pink. Management in cases of pigmentation using the surgical method by scrapping using a scalpel No.15. In this study there were 3 cases, namely, case 1, a 20-year-old female patient had genetic or genetic hyperpigmentation. Case 2, a 27-year-old male patient had genetic or genetic hyperpigmentation. Case 3, a 24-year-old female patient had gingival pigmentation due to smoking habits. The results of surgical management in all three cases, namely the gingival depigmentation method by scrapping gave a good esetetic result, but for gingival hyperpigmentation in cases 1 and 2 it could recur later.

Ultrafiltrasi merupakan salah satu teknologi penjernihan yang dapat diterapkan untuk mengatasi rendahnya kualitas produk sari belimbing UKM Mulyasari. Tujuan dari penelitian ini ialah: 1) untuk menghasilkan rancangan mesin ultrafiltrasi yang praktis dan ekonomis; 2) untuk mengetahui performansi mesin ultrafiltrasi; 3) untuk mengetahui kesetimbangan massa  proses ultrafiltrasi; serta 4) untuk mengetahui pengaruh penggunaan mesin ultrafiltrasi terhadap kualitas produk, tingkat produksi, serta efektifitas dan efisiensi kerja. Uji performansi dilakukan menggunakan 4 perlakuan tekanan kerja, yaitu 0,5; 1,0; 1,5; dan 2 bar. Variabel tetap yang digunakan berupa volume sari buah masing-masing 15 L dan waktu filtrasi  5  menit. MORFIN (Modified Ultrafiltration Machine) merupakan mesin ultrafiltrasi yang dibuat  praktis setinggi 100 cm dengan biaya operasional Rp18.000,00/bulan. Hasil pengujian menunjukkan laju filtrasi terbesar  terjadi pada tekanan 2 bar,  yakni 111,6 L/jam. Di samping itu, rasio massa permeate-retentate mengalami peningkatan seiring dengan peningkatan tekanan kerja. Rasio massa permeate-retentate terbesar terjadi pada tekanan 2 bar yakni 8,089:5,44 (kg), atau dengan persentase 60,6:39,34 (%). Di lain hal, hasil pengujian menunjukkan permeate memiliki kualitas yang lebih baik. Ini berdampak pada peningkatan umur simpan produk dari 10 hari menjadi 60 hari. Pengaplikasian mesin ultrafiltrasi di UKM Mulyasari mampu meningkatkan kapasitas produksi hingga 4 kali lipat. Selain itu, kualitas produk serta efektifitas dan efisiensi kerja juga mengalami peningkatan.   Kata kunci: penjernihan, performansi, permeate, praktis, retentate

Abstract

South Tangerang City Government set it Situ (small lake) Kedaung as one of the conservation program, because of 9 there were 4 of which have been lost or switching functions, and 3 endangered missing, one of them is Situ Kedaung. For it is necessary to study the level of sustainable conservation to utilization Situ Kedaung. This study aims to analyze the index and status sustainability of 5 (five) dimensions of sustainability, using the data step Multi-Dimensional Scaling (MDS), and the results are expressed in the form of index and status of sustainability. To determine the attributes that are sensitive and affect the index and status sustainability and influence of Laverage and Montecarlo analysis. As for the scenarios increase the sustainability of the future status is a prospective analysis. The analysis showed that the ecological dimensions of sustainability are at less status (37.32), the economic dimension is the less sustainable status (26.05), the social dimension is the less sustainable status (40.28), the dimensions of the technology is fair sustainable status (57.20), and institutional dimensions are less sustainable (26.91). The results of the analysis of all the dimensions of sustainability for situ Kedaung is included in the category or status less sustainable with index value of 36.65. Of the 37 attributes that were analyzed, there were 14 attributes that need to be addressed as it is sensitive affect. Based on a prospective analysis, there are 5 critical attributes that must be managed in order to maintain sustainability. These five attributes include: water pollution, eco-tourism, conservation, community income, and local regulatory agencies, hereinafter referred to as key attributes. To improve the status of sustainability in the future (over the medium and long term), there are three scenarios : (1) Conservative-Pessimistic (survive the conditions that exist while holding make shift repairs), (2) moderate- Optimistic (make improvements but not optimal) and (3) Progressive- Optimistic (make comprehensive and integrated improvements).
