The Collaborative Work Lecture with BKS West PTN is one of the community service programs conducted by 20 state universities where the University of North Sumatra is the host of the program. In the KKN program, we realize one of the tri dharma of higher education namely community empowerment. The aim of this program is that students are expected to gain learning experience through involvement in the community who directly find, formulate, solve and overcome problems that are in the field. The Community Service Program that we carry out is devoted to the community in Haranggaol Village, Haraggaol Horison District, Simalungun Regency, North Sumatra Province with the program "Community Empowerment of the Haranggaol Village, Haranggaol Horison District, Simalungun Regency, North Sumatra Province in an Effort to Improve Local Wisdom and Ecotourism in the Region of North Sumatra. This program is expected to be able to contribute to the community in the form of helping improve basic facilities and infrastructure as well as increasing the human resources available in the Haranggaol Basin so that local wisdom and ecotourism are of higher quality and help local communities maintain natural resources so that they are sustainable

Kegiatan IbM Kelompok Tani Jagung dan Coklat ini bertujuan 1) memberi solusi kepada mitran Kelompok Tani Jagung Sejahtera dan Kelompok Tani Coklat Saroha untuk mengatasi kekuranganpupuk organik dengan memanfaatkan limbah tanaman jagung dan coklat yang cukup melimpahn dalam usaha meningkatkan produktivitas tanaman dan mensukseskan program pertanianorganik, 2) membuka peluang membuka usaha baru pupuk organik. Target khusus yang ingin dicapai adalah publikasi jurnal, laporan kegiatan, aspek produksi dan manajemen. Luaran kegiatan adalah produk pupuk organik limbah tanaman jagung dan coklat berkualitas (fisik dan kandungan unsur hara), desain alat perajang mekanik limbah pertanian dan rencana bisnis sederhana pupuk organik. Metode yang diterapkan adalah penyuluhan, rancang alat perajang mekanik limbah organik, pelatihan dan peraktek produksi serta penyuluhan perencanaan bisnis sederhana pupuk organik. Kegiatan melibatkan tiga orang dosen dan dua mahasiswa. Mitra kegiatan adalah kelompok tani jagung Sejahtera dan kelompok tani coklat Saroha. Hasil kegiatan menunjukkan bahwa 80 % kelompok tani kedua mitra mampu mengolah pupuk organik dari limbah kulit coklat dan limbah batang serta daun jagung dalam waktu 10 hari. Kualitas tekstur pupuk organic baik yaitu tidak berbau, tidak berair, gembur, tidak panas dan warnanya hitam. Kualitas unsur hara .masing-masing pupuk limbah jagung, coklat dan campuranlimbah jagung dan coklata dalah ratio C/N 8,4; 8,8 dan 9,0 yang sudah mendekati ratio C/N tanah, kadar KO 1,60 %; 1,52% dan 1,58% serta kadar P2O adalah 3,15%; 2,50% dan 3,00%. Hal ini menunjukkan bahwa zat organik limbah telah terurai menjadi unsur hara yang menyuburkan tanah dan mudah diserap 5 tanaman. Kelompok tani mitra mengembangkan pembuatan pupuk dengan menggunakan limbah tanaman/batang pisang yang ada di lokasi pada saat sebelum panen jagung. Kapasitas alat perajang mekanik yang digunakan dapat memotong 500 kg limbah pertanian/jam. Sebanyak 50% kelompok tani mitra berminat berwirausaha baru pupuk organik dan 50% lagi sementara hanya untuk memenuhi kebutuhan pupuk tanamannya. Kelompok tani mitra ini memerlukan pembinaan lanjutan baik dalam penyempurnaan produksi, pengemasan maupun pemasaran produksinya.

Food safety issues have become a global concern because hundreds of millions of people suffer from diseases due to contaminated food. Food poisoning cases in Indonesia continue to increase from year to year. In 2013, the POM reported that there were 48 outbreaks (KLB) of food poisoning from 34 provinces in Indonesia. In Tanjung Morawa Subdistrict, especially Mardisan Village, there are many food vendors, ranging from food for breakfast, various snacks during the day to night. In this area there are also many flower sellers, so the village is always busy with flower buyers. In addition to buying flowers, they generally also need food and drinks so that food vendors in this area are also growing. However, very often these food traders do not pay attention to food safety requirements because they are tempted by the maximum profit. For this reason, dedication is carried out to increase the knowledge and skills of traders in processing healthy and natural foods without using additives that are harmful to health. Training was carried out on increasing partners' knowledge in the use of additives permitted by the Minister of Health as an effort to reduce the use of additives that are harmful to health. The training was carried out by using the lecture method, discussion by giving lieaflead to food sellers. The food vendors are very enthusiastic about participating in the training with many questions from the participants about allowed and not allowed food substances. The traders promised to implement natural and healthy food processing methods without using additives that are harmful to health. The head of the food merchant group will monitor the food safety in this area so that natural and healthy food is still sold in Mardisan.

This study uses raw materials containing lignocellulose, namely empty fruit bunches of oil palm. Oil palm empty fruit bunches were isolated to produce cellulose, hydrolyzed into simple sugars, fermented, and distilled. From the isolation of cellulose obtained α-cellulose of 19.9612 grams (26.6149%). Then it was hydrolyzed using HCl with a concentration variation of 15%; 20%; 25%; 30%; and enzymatically hydrolyzed using cellulase to produce simple sugars which were tested qualitatively with Benedict's reagent and Tollens reagent, then quantitatively tested by the Luff Schroll method. The higher the concentration of acid used, the higher the sugar will be. The best bioethanol obtained from acid hydrolysis is using 30% HCl with ethanol content of 6.54% and enzymatic 7.32%.

The production of Ethanol has been utilized through the process of cellulose isolation from agricultural waste such as corn husk, rice straw and rice husk. Isolation of cellulose with pretreatment delignification using, NaOH 2% to produces cellulose of corn husk 16,6921 g (22,25%), rice straw 16,9021 g (22,53%) and rice husk 16,3691 g (21,85%) then analyzed the functional groups using FT-IR and SEM analysis. Cellulose as much as 2 g is hydrolyzed using HCl 30% and cellulase enzymes to obtain sugar that is qualitatively tested with Benedict and Tollens reagent and quantitatively tested with Luff Schoorl method and produces highest sugar content of rice husk 8,64% and 10,95%. The next stage sugar of hydrolysis will be fermented using yeast (Saccharomyces cerevisiae) with 6 days, and then distilled at a temperature of 78-80oC. Ethanol was calculated by the potassium dichromate oxidation method to gave highest result from agricultral waste of ethanol chemical 5,97% and enzymatic 6,89% is rice husk.

The fatty alcohols C8, C10, C16 and C18 were used as raw materials for the sulfation reaction using the SO3-DMF complex to study the ratio of carbon chains. The first step is to prepare the SO3-DMF complex, by reacting SO3 gas into DMF at a temperature of 0-4 0C with a reaction time of 3 hours, then sulfation is carried out at 100 0C for 5 hours on C8, C10, C16 and C18. Tests were carried out on the results of sulfation with an FT-IR Spectrophotometer. Surface tension, foam stability and yield calculations. From the sulfation results, the yield results were respectively 83%, 81%, 68% and 61% then the results from the surface tension analysis were 35.3, dyne/cm, 30.3 dyne/cm, 29.4 dyne/cm and 33.6 dyne/cm and foam stability analysis of 0.2 cm, 0.8 cm, 0.7 cm and 1 cm. Based on the surface tension reduction value, palmityl alcohol is the best raw material for making surfactants.
