Sweet potato starch has limited uses in food industry, but modification of its properties may make it more suitable for use especially for starch based food such as bihon type noodle. The objective of this research was to study the effect of heat moisture treated starch from 4 varieties of sweet potato on the quality of its bihon type noodle. Four different varieties of sweet potato i.e. white, yellow, orange and purple tuber were treated with heat moisture treatment (HMT). The HMT was performed by exposing the starch to high temperature (110°C for 3 hours) at a moisture content of 25%. The HMT modified sweet potato starch was then processed into bihon type noodle. As a control, a commercial bihon type noodle made from rice starch was used. Parameters evaluated were the modified starch and bihon properties. The results showed that the modification of starch with HMT could increase the peak viscosity, setback viscosity, final viscosity and gelatinization temperature but lower the value of the breakdown viscosity. The best bihon from the four varieties of sweet potatoes was that made from white sweet potato starch because it has low cooking losses, low fat, but has high color/brightness and is preferred by panelist.Keywords: bihon, heat moisture treatment, starch, sweet potatoes ABSTRAK Keterbatasan pemanfaatan pati alami di dalam industri pangan dapat diatasi dengan cara modifikasi pati sehingga dihasilkan pati dengan karakteristik yang diinginkan terutama pada produk pangan berbahan dasar pati seperti bihun instan.

Kabupaten Mandailing Natal merupakan daerah penghasil kopi di Sumatera Utara. Salah satu factor pembatas produksi kopi di kabupaten ini adalah adanya serangan penyakit karat daun yang disebabkan oleh Hemileia vastatrix. Namun informasi sebaran dan keparahan penyakit karat daun kopi di kabupaten ini belum ada.Padaha linformasi ini diperlukan untuk menentukan strategi pengendalian yang tepat. Penelitian ini bertujuan untuk mengetahui keparahan penyakit dan pemetaan sebaranpenyakit karat daun kopi pada perkebunan kopi rakyat di Kabupaten Mandailing Natal. Penelitian dilaksanakan dengan metode purposive random sampling (PRS) di tiga kecamatan masing-masing Kecamatan Pakantan, Puncak Sorik Marapi dan Ulu Pungkut dengan lokasi geografis 0° 10° – 1° 50° LU dan 98° 50° – 100° 10° BT dengan ketinggian tempatantara 861-1353 meter diatas permukaan laut. Hasil penelitian menunjukkan penyakit karat daun kopi telah tersebar pada letak geografis 0°10°-1°50°LU dan 98°50°-100°10°BT dengan keparahan penyakit karat daun kopi tertinggi yaitu 45% terdapat di Desa Huta Namale, Kecamatan Puncak Sorik Marapi, sebaliknya keparahan penyakit karat daun kopi yang terendah terdapatdi Desa Huta Julu, Kecamatan Pakantan yaitu sebesar1%. Faktor suhu, ketinggian tempat dan jarak tanam berkorelasi sangat rendah terhadap tingkat kejadian dan keparahan penyakit karat daun kopi. Mandailing Natal Regency is a coffee-producing area in North Sumatra. One of the limiting factors for coffee production in this district is the attack of coffee leaf rust disease caused by Hemileia vastatrix. The information on the distribution and severity of coffee leaf rust disease in this district is needed to determine its control strategy. This study aims to determine the severity of the disease and the mapping of the spread of coffee leaf rust disease on people's coffee plantations in Mandailing Natal District. The study was carried out by purposive random sampling (PRS) method in three sub-districts of Pakantan Subdistrict, Sorik Marapi and Ulu Pungkut Peak with a geographical location of 0 ° 10 ° - 1 ° 50 ° N and 98 ° 50 ° - 100 ° 10 ° with the altitude between 861-1353 meters above sea level. The results showed that the coffee leaf rust disease was spread over a geographical location of 0 ° 10 ° -1 ° 50 ° N and 98 ° 50 ° -100 ° 10 ° East with the highest severity of coffee leaf rust disease, 45% in Huta Namale Village, District Sorik Marapi Peak, on the contrary the lowest severity of coffee leaf rust disease is in Huta Julu Village, Pakantan District, which is equal to 1%. Temperature, altitude, and spacing factors are very low correlated with the incidence and severity of coffee leaf rust disease.

The aim of this study was to determine and analyze the relationship self eficacy and family social support with career maturity.

Islamic counseling guidance in this study focuses on the treatments done by applying the Al-Qur'an and Al-Hadith approach. This research has three goals; (1) to analyze the mental health care technique used by the Ustadz (teacher) in Pesantren Musthafawiyah ; (2) to analyze the aspects of the treatments given in Pesantren Musthafawiyah ; and (3) to analyze the nurturing mental efforts made by the Ustadz in Pesantren Musthafawiyah. The qualitative approach using three instruments of data collection, namely; observation, interview, and documentation was applied in this research. The findings of this research show that the Islamic counseling technique used by the Ustadz was done through group organization or group guidance approach, while Islamic approach was used as the aspect of the treatments given. The mental nurturing efforts are based on Islamic Pillars, the Six Articles of Faith, and Ihsan (perfection) with the major priority of akhlakul karimah (the practice of virtue, morality, and manners).
