Abstract

The imbalanced supply-demand of soybean is the main reason of soybean import in Indonesia. One of the efforts to increase of soybean production was expanding the planting area to acid soil with a low pH, high content of Aluminum, and low nutrient availability, through giving ameliorant, such as liming organic materials, and mineral fertilization.This study was aimed to obtain the best combination of fertilizer and amelioran for soybean production in acid soil. The study was conducted in experimental station of Tenjo, Bogor from November 2015 to March 2016. The experiment used a randomized complete block design with two factors. The first factor was combinations of fertilizer and amelioran, i.e., P0 (without fertilization); P1 {25 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) ha-1}; P2 {25 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) + 1,250 kg of manure ha-1}; P3 {50 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) + 2,500 kg of manure ha-1}; P4 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ¼ x Aldd (805 kg) + 2,500 kg of manure ha-1}; P5 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ½ x Aldd (1,610 kg) ha-1}; P6 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomites 1 x Aldd (3,220 kg) ha-1}. The second factor was soybean varieties of Tanggamus and Anjasmoro. The results showed that application of 75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ½ x Aldd (1,610 kg) produced the highest productivity (2.91 ton ha-1), but it was not different from reducing the dose of dolomite into ¼ x Aldd (805 kg) with the addition of 2,500  kg of manure.

Abstract

Salah satu varietas salak yang berpotensi besar untuk dikembangkan selain salak pondoh dan salak bali adalah salak sidimpuan. Salak sidimpuan belum mampu bersaing karena mutu buah salak yang masih beragam. Penelitian bertujuan untuk mengetahui perbedaan kandungan kimia pada buah salak sidimpuan yang manis dan asam. Penelitian dilaksanakan di kebun salak Desa Palopat Maria Kel Hutaimbaru kota Padangsidimpuan pada bulan Agustus 2020. Analisis kandungan kima yang diuji antara lain PTT, ATT, dan Vitamin C yang dilakukan di Laboratorium Balai Penelitian Tanaman Buah Tropika, Sumatera Barat. Metode yang digunakan dalam pengambilan sampel buah adalah dengan metode judgment sampling (purposive sampling). Jumlah buah salak yang diamati sebanyak 10 sampel untuk masing-masing salak yang manis dan asam. Hasil penelitian menunjukkan bahwa rata-rata nilai kandungan padatan terlarut total (PTT), asam tertitrasi total (ATT), rasio PTT.ATT-1, dan vitamin C buah salak sidimpuan manis : asam berturut-turut adalah 18,68 : 20,13 oBrix; 0,71 : 1,18 oBrix; 28,62 : 18,46; dan 51,73 : 48,32.

Abstract

Community service is important to do in order to develop the order and standard of living of the people in an area. One of them is in Nagari Sungai Kambut where many of the residents are not yet working or not working and some are only taking care of the household. In fact, when viewed from its natural potential, the Nagari Sungai Kambut region has quite a large potential for productive land, including the home yard. Therefore, dedication is carried out in the form of assistance in optimizing the use of the home yard for planting fruits. The hope is to increase the knowledge and improve the skills of the local population. The fruit produced can also be a source of income, apart from just for self-consumption. Service activities begin with socialization, counseling and followed by assistance in planting fruit trees. Farmers are guided and assisted by the team so that when there are problems they can be immediately resolved. During the socialization, the residents actively raised various questions, both from how to plant, maintain and even post-harvest. Seeing the enthusiastic response of the community shows that this service program has been able to increase knowledge about the importance of using the home yard, especially for planting fruits. Overall, a series of community empowerment activities through planting fruits in order to optimize the use of the home yard has given positive impact on the community. Appropriate cultivation techniques will provide benefits to society by increasing crop productivity. The product can be consumed or sold and participate in protecting the environment so that it remains sustainable. The enthusiasm of community was the evidence of their high curiosity and indicator of the successfulness of this activity.

Abstract

Produk turunan kelapa sawit yang harus dijaga selain CPO (crude palm oil) ialah KPO (kernel palm oil). Minyak kernel (KPO) yang baik tergantung dari hasil pengolahan biji sawit pada stasiun pengolahan biji, tepatnya pada stasiun pemecah biji oleh mesin nutcracker. Penelitian ini telah mengkaji kinerja 4 mesin nutcracker pada pabrik kelapa sawit PTPN VWXYZ sebanyak 3 ulangan per mesin nutcracker (200 g bahan untuk tiap ulangan) dengan tiga perlakuan kadar air (berdasarkan waktu pengambilan data di hari yang sama). Beberapa parameter yang dihitung adalah nilai persentase nilai biji utuh, biji pecah tidak sempurna, kernel pecah, dan efisiensi mesin nutcracker. Adapun tujuan penelitian ini untuk mengkaji tingkat efisiensi dari mesin nutcracker, sehingga akan dihasilkan kernel dengan kualitas yang baik dan apabila terjadi ketidak sesuaian dengan standar pabrik maka akan dapat dilakukan segera maintenance. Berdasarkan hasil penelitian yang telah dilakukan diperoleh nilai efisiensi mesin nutcracker sebesar 94% dan nilai kernel pecah pada rentang nilai 0.117-0.593%. Nilai kernel pecah sebagai inti dari pengolahan pada stasiun pengolahan biji di PTPN VWXYZ masih sesuai dengan parameter SNI 01-0002-1987 (maksimal 15%) dan standar pabrik (maksimal 12%). Artinya mesin yang bekerja pada saat pengamatan masih layak untuk beroperasi. Selanjutnya, tetap perlu dilakukan routine maintenance untuk menjaga kualitas pemecahan biji oleh nutcracker agar senantiasa sesuai dengan standar dan menjaga efisiensi kerja mesin tetap di atas 90%.

Abstract

Achievement level of input use efficiency will determine the success of farmers in achieving maximum production and income from farming and agro patchouli and can compete in the market. The research aimed to analyze system of patchouli agroindustry conducted from production technology, input using, cost, production, income and patchouli agroindustry efficiency and marketing sub-system conducted from channel, marketing organization, cost, profit and marketing efficiency in Guo Batu Village, Mandailing Natal Districk, North Sumatra Province. Census method used in this research with 30 farmers as sampling. The average of agroindustry sub-system production 116,70 kg of patchouli oil per production process, gross income Rp. 64,185,000 and net income Rp. 41,453,091.67. family income Rp. 45,185,076.53 and RCR 2,90. The conclusion is the marketing doesn’t have problem because the farmers sell the patchouli in oil directly to traders with the price Rp. 550,000/kg.

Abstract

Trees of sugar palm (Arenga pinnata Merr.) can grow at an altitude of 0-1400 m above sea level. The best growth of the trees is at an altitude of 500-700 m above sea level. Sugar palm trees also have a wide adaptability to various environmental conditions. The purpose of this research was to determine the morphological characteristicss of sugar palm plants grown at an altitude of 500, 650, and 900 m above sea level so that the kinship relationship can be known. This research was conducted at three altitudes in Lareh Sago Halaban District, Lima Puluh Kota Regency, West Sumatra, namely Nagari Labuah Gunung (altitude 900 m above sea level), Nagari Bukik Sikumpa (altitude 650 m above sea level), and Nagari Tanjung Gadang (altitude 500 m above sea level) from July to August 2023. The method used was a survey with a purposive sampling technique. Identification was carried out on 36 morphological characters, including stems, leaves, fibers, fruits, and seeds. The data obtained were analyzed for their diversity and similarity. The results of the identification and characterization of qualitative and quantitative morphological characters at three different altitudes showed a relatively narrow diversity value. The overall morphological characters of the sugar palm plants were divided into 2 large groups with a coefficient value of 0.72 or 72% similarity distance.
