Bungkil Inti Sawit sebagai Media Biokonversi Produksi Massal Larva Maggot dan Uji Respon Pemberian pada Ikan Nila (Oreochromis niloticus)
The results of palm kernel extraction produce palm kernel oil (PKO) and by-products in the form of palm kernel meal (PKM). Utilization of PKM as a raw material for fish feed, another development of its utilization is as a medium for the bioconversion process in producing maggot, the larvae of Hermetia illucens known as the Black Soldier Fly (BSF) as fish feed. Bioconversion is a process that changes the shape of a product / material that is less valuable into a valuable product by using biological agents (living things: insects). Mass production of maggot larvae is carried out through the stage of BSF egg production in the cage. The eggs harvested are then stocked on fermented PKM media using probiotics mixed into water at different doses, namely: 0% (F0), 1% (F1), 2% (F2), 3% (F3), and 4% (F4), water + probiotics are mixed into PKM media weighed 1 kg each until the media becomes moist and left for 2 days. Then the petri dish is filled with eggs 1 gram each and placed on the PKM media. The bioconversion process takes place 7-10 days later maggot larvae can be harvested. The highest maggot biomass in 3% (F3) + probiotic water fermentation treatment is 805 grams / kg media, the highest percentage of maggot size is medium (1-1.5cm) 35-66% with the highest protein content of 50.58%, while the small size ( <1cm) 21-32% protein 48.67% and large size (> 1.5cm) 21-30% with protein 48.58%. Giving maggot larvae as fresh feed is very well responded by fish. Keywords: Palm Kernel Meal (PKM), Bioconversion, Biomasa Maggo
Rancang Model Implementasi Kebijakan Publik Melalui Pendekatan Nilai Budaya Lampung

Based on a study of the case study of the sambayan sakay value in Tulang Bawang Regency, which was included, included in the implementation of the Simultaneous Building Village (GSMK) Movement program. perceptions of leaders, that the process of formulation and approach to implementation is designed according to the direction of thought leaders towards the surrounding cultural environment Second, cultural values. Cultural values are the basic foundation used as guidelines for implementing implementation. A culture that is easy to understand and is universal in its manifestation with gambling is adopted in the implementation of the program. The habit of the community about the culture also supports the successful implementation of the program. You can imagine when the culture is not known by the local community, of course it cannot be embodied. Third, System, Strategy and Structure (3S). These three factors are the shield of how the results of the leader's perception of the environment make it a cultural value. Both those born from the leader's own perception or cultural values that already exist in the community. The two factors then gave birth to a formulation related to the program system that will be implemented, a strategy on how the cultural values will guide the implementation and formation of the policy implementation structure. Keywords: policy implementation, cultural approach, sakay sambayan value
Faktor yang Mempengaruhi Keputusan Petani Pisang di Lampung
Banana production in Lampung is currently the third largest in Indonesia after the Provinces of West Java and Central Java. Lampung Province accounts for 12.38 percent of total banana production in Indonesia (Agricultural Data and Information Center, 2014). Bananas are horticultural commodities that are easily cultivated and produce throughout the year. Banana production is sold in fresh and processed form. The availability of bananas as a raw material for making banana chips is still an obstacle. The decision of farmers in Lampung to produce bananas has not been directed at meeting the needs of the banana industry's raw material. Information about factors that influence farmers' decisions in banana farming is important to know in order to solve the problem of the availability of raw materials in the banana chips industry. The method used in this study is the survey method. Data were analyzed using factor analysis. These factors are: pests and diseases, selling prices, market access, and varieties. Each factor has a weight of 1081, 0.947, 0.956 and 1,184. Keywords: banana, factor analysis, farmer’s decisio

The feed has a high contribution of around 75% in production costs. The purpose of this Final Project Report is to understand the feed management of beef cattle at PT Indo Prima Beef. Data was collected using interviews, observation, and library methods. Feed planning is done 2 times, in the morning ± 06.00 to see the consumption of the night and during the day ± 13.00 to see the morning consumption. Feed distribution at PT Indo Prima Beef is divided into 2, the distribution of forage feed and the distribution of concentrate feed. PT Indo Prima Beef made 2 types of concentrates which named F8 and F9. F8 is a concentrate that has 20% protein content and 63% of energy (TDN). F8 concentrate was made for the grower period while F9 concentrate made for the finisher period. F9 has a higher energy content (TDN) of 69% and a lower protein content of 18%.  Keywords: beef cattle, feed, managemen
Pertumbuhan Vegetatif, Akar, dan Nodula Tanaman Kacang Hijau (Vigna radiata L.) Akibat Pemberian Kompos Azolla (Azolla pinnata) Bentuk Pellet dan Calsium Carbonate (CaCO3) Tanah Ultisols Masam
Ultisols are the most extensive land order, reaching 48.3 million hectares or 29.7% of the land area of Indonesia. Development of food crops and horticulture farming on this land will face many obstacles related to the nature of this land. Ultisols are soil that is sensitive to erosion, low fertility and reacts sourly to very acidic.Ultisols are generally low in soil fertility caused by high levels of acidity, low nutrient content of N, P, K, Ca, Mg, S and Mo and high levels of Al, Fe and Mn elements which often reach levels that are harmful to growth. . In addition, the high element Al, Fe da Mn in Ultisols can also bind P nutrients into insoluble and not available to plants. This study aims to obtain the composition of azolla (Azolla pinnata) form of pellets and calcium carbonate (CaCO3) which can provide the highest growth and yield of mungbean (Vigna radiata) plants in acidic Ultisols. The study was carried out in the Lampung State Polytechnic practice garden, from July 2018 to October 2018. The study was arranged in factorial in a randomized block design (RBD) with 16 treatment combinations and 3 replications, so that there were 48 experimental units. The treatment combination is as follows: The first factor is the dose of pelleted azolla compost (A) which consists of 4 levels, namely: a0 = without azolla compost, a1 = 10 tons ha-1, a2 = 20 tons ha-1, and a3 = 30 tons ha- 1. The second factor is the Dolomite dose (D) which consists of 4 levels, namely: c0 = without dolomite c1 = 1.5 tons Ha-1Dolomite, c2 = 3 tons Ha- 1Dolomite, and c3 = 4 tons Ha-1 Dolomite. The target to be achieved in this study is to find out the response of the variables observed, namely: (1) plant dry weight (g), (2) root dry weight and (3) number of root nodules (grains). Pelleted azolla compost increase the growth of root nodules, root dry weight and shoot dry weight of mung bean on the Taman Bogo Lampung Ultisols soil. Dolomite increases the number of root nodules but has no significant effect on the root dry weight and shoot dry weight of mungbean on the soil of Taman Bogo Lampung Ultisols. Compost azolla and dolomite lime work independently on the lands of the Bogo Lampung Taman Ultisols. Keywords: Ultisol, Pelleted Azolla Compost, Dolomite, Mung Bean (Vigna radiata L
Antisipasi Kerusakan Motor Listrik 3 Fasa pada Peralatan Laboratorium Pendidikan dan Unit Produksi Sabutret Menggunakan Pengaman Phase Failure Relay
